connecting axle (15) and Connection Block (17), B, again the male cone (strobilus masculinus) of cleat stanchion (2) (10) insert load bearing seat (1) Inner taper hole (12) in, under the effect of self gravitation, the male cone (strobilus masculinus) (10) of cleat stanchion (2) and the inner conical surface (11) of load bearing seat (1) are naturally fitted and fix, and larger from the gravity of cleat stanchion (2) pressure, it is closely and more more firm that inner conical surface (11) and male cone (strobilus masculinus) (10) are fitted, male cone (strobilus masculinus) (10) in cleat stanchion (2) inserts in the process of Inner taper hole (12), during inner conical surface (11) position that locking head enters into, inclined-plane on inner conical surface (11) oblique promotion locking head makes locking head compress thrust spring (8) and outside oblique yielding, when the male cone (strobilus masculinus) (10) of cleat stanchion (2) contacts firm with the inner conical surface (11) of the Inner taper hole (12) of load bearing seat (1), locking head just in time enters the position of annular lock groove (9) after slipping over the inner conical surface (11) above annular lock groove (9) smoothly, locking head enters in annular lock groove (9) under the powered of thrust spring (8), to coordinate with the inner conical surface of fitting (11) with the locking face of the annular lock groove of V-arrangement (9) and male cone (strobilus masculinus) (10) is locked can not retreat by facing directly of locking head, complete cleat stanchion (2) and the fixing of load bearing seat (1) and locking, C, point-blank whether the center line of vertical bar of observation gravity cone (19) and the parallel lines of the center line of cleat stanchion (2), time not point-blank, the upper end of moving the cleat stanchion (2) inserted on load bearing seat (1) makes the parallel lines of the center line of cleat stanchion (2) and gravity bore the center line of the vertical bar of (19) point-blank, the lock bolt (18) be rotationally connected again on seat (17) compresses the lower part of load bearing seat (1), load bearing seat (1) can not be rotated around connecting axle (15), holder (16) is allowed to remain unchanged with the angle of load bearing seat (1), guarantee is arranged on cleat stanchion (2) above load bearing seat (1) perpendicular to horizontal plane, time point-blank, the lock bolt (18) be just directly rotationally connected on seat (17) compresses the lower part of load bearing seat (1), load bearing seat (1) can not be rotated around connecting axle (15), allow holder (16) remain unchanged with the angle of load bearing seat (1), ensure that the cleat stanchion (2) be arranged on above load bearing seat (1) is perpendicular to horizontal plane, D, again the Inner taper hole (12) of joint pin is enclosed within the male cone (strobilus masculinus) (10) of the upper end of cleat stanchion (2), afterwards, again the male cone (strobilus masculinus) (10) of another root cleat stanchion (2) is inserted in the Inner taper hole (12) of connector (3) in the Inner taper hole (12) of joint pin again, under the effect of the gravity of self gravitation and carrying, the male cone (strobilus masculinus) (10) of cleat stanchion (2) and the inner conical surface (11) of connector (3) are naturally fitted and fix, and it is larger from the gravity of connector (3) or cleat stanchion (2) pressure, it is closely and more more firm that inner conical surface (11) and male cone (strobilus masculinus) (10) are fitted, male cone (strobilus masculinus) (10) in cleat stanchion (2) inserts in the process of Inner taper hole (12), during inner conical surface (11) position that locking head enters into, inclined-plane on inner conical surface (11) oblique promotion locking head makes locking head compress thrust spring (8) and outside oblique yielding, when the male cone (strobilus masculinus) (10) of cleat stanchion (2) contacts firm with the inner conical surface (11) of the Inner taper hole (12) of connector (3), locking head just in time enters the position of annular lock groove (9) after slipping over the inner conical surface (11) above annular lock groove (9) smoothly, locking head enters in annular lock groove (9) under the powered of thrust spring (8), to coordinate with the inner conical surface of fitting (11) with the locking face of the annular lock groove of V-arrangement (9) and male cone (strobilus masculinus) (10) is locked can not retreat by facing directly of locking head, when the cleat stanchion (2) of E, employing multilayer forms power equipment maintaining vertical ladder, it is upper or again inserted by the male cone (strobilus masculinus) (10) of cleat stanchion (2) in the Inner taper hole (12) of joint pin below that the inner conical surface (11) of joint pin can be enclosed within the male cone (strobilus masculinus) (10) of cleat stanchion (2) by step and method again that repeat D step, completes being connected and fixed and locking between cleat stanchion (2) and joint pin, cleat stanchion (2) is very convenient with the assembling of load bearing seat (1) and cleat stanchion (2) and connector (3), just can complete without any need for instrument,When the cleat stanchion (2) of dismountable is with joint pin, pull the pin handle of self-lock pin (6), after the locking head of self-lock pin (6) front end exits the annular lock groove (9) on inner conical surface (11), cleat stanchion (2) or connector (3) upwards one are drawn or one to be lifted, and the male cone (strobilus masculinus) (10) of cleat stanchion (2) will separate automatically with the Inner taper hole (12) of connector (3);

    Time dismounting load bearing seat (1) upper fixing cleat stanchion (2), pull the pin handle of self-lock pin (6), after the locking head of self-lock pin (6) front end exits the annular lock groove (9) on male cone (strobilus masculinus) (10), cleat stanchion (2) upwards one is drawn or one lifts and automatically will separate with the Inner taper hole (12) of load bearing seat (1), and cleat stanchion (2) will separate automatically with load bearing seat (1);

    Cleat stanchion (2) is very convenient with the dismounting of load bearing seat (1) and cleat stanchion (2) and connector (3), just can complete without any need for instrument;

    High-tension line maintenance personal is when examination and repair for high-pressure circuit, run into when having branch Distance High Voltage Electricity Transfer very near or line joint need maintenance time, first holder (16) is placed steadily on the ground, combining holder (16) again, Connection Block (17), the load bearing seat (1) of connecting axle (15) and load bearing seat (1) plug first cleat stanchion (2) above after, the cleat stanchion (2) and joint pin that need height are taken with oneself, pin steps down on the foot hold on cleat stanchion (2) and climbs up, one section of assembling one section can be climbed, when climbing to the top of ladder in the process of cat ladder, superincumbent male cone (strobilus masculinus) (10) puts after inserting a cleat stanchion (2) again in joint pin or superincumbent Inner taper hole (12) and climb up again, during descending stair, step down on foot hold and down climb, next section tears a cleat stanchion (2) or joint pin open, very convenient.
