1. the treadmill with limited block and draw ring, comprise base (4), and the accommodation storehouse (5) be arranged in base (4), and be arranged on the treadmill body (3) at base (4) top, and be connected to the operation panel support bar (8) for being connected with operator'"'"'s operation panel (80) at left end place of base (4), described support bar (8) comprises and is provided separately thus is positioned at two support arms (81 of described base (4) both sides with the longitudinal axis of described support bar with being symmetrical arranged, 82) and be fixedly connected on described two support arms (81,82) the cydariform connecting axle (810) between, described support bar (8) is hinged with the connection sliding block (9) that can slide in described accommodation storehouse (5) by described cydariform connecting axle (810), described connection sliding block (9) right side is provided with stay cord (6), described base (4) the right is provided with the perforation (41) be connected with described accommodation storehouse (5) and passes with for the stay cord (6) being arranged on connection sliding block (9) right side, described stay cord (6) right side is provided with draw ring (61), described base (4) right flank is also provided with the rack (7) for placing described stay cord (6) and draw ring (61), the setting of described stay cord (6) and draw ring (61) is in order to be drawn in described accommodation storehouse (5) by described connection sliding block (9), the right in described accommodation storehouse (5) be provided with limited block (100) in order to the motion of described connection sliding block (9) is carried out spacing thus prevent described connection sliding block (9) from sliding in accommodation storehouse (5) time and described base (4) collide, be provided with cavity (92) in described connection sliding block (9) separate symmetrically arranged two circular orientation slide blocks (923) with the perpendicular held about described longitudinal axis place and allow described two circular orientation slide blocks (923) to slide on the axis direction of described cydariform connecting axle (810), described cydariform connecting axle (810) is provided with two symmetrical conical section (921) with respectively with bellmouth (9230) frictional fit in two circular orientation slide blocks (923) to position relative to relatively rotating of described connection sliding block (9) described cydariform connecting axle (810), described two circular orientation slide blocks (923) are each is all fixedly installed two catch bars (9232) setting up and down that can stretch out in and be retracted to described connection sliding block (9), described two support arms (81,82) inner side is provided with the lug (812) of vertical raised line (811) and horizontal direction distribution, thus when described support bar (8) vertically location time described vertical raised line (811) can coordinate with the wedge surface junction surface (9231) of described catch bar (9232) end thus described two circular orientation slide blocks (923) inwardly be pushed resist and be arranged at Compress Spring (922) between described circular orientation slide block (923) and described connection sliding block (9) accordingly to make described bellmouth (9230) friction fit taper part (921), when described when described support bar (8) horizontal location time described horizontal direction distribution lug (812) can described two circular orientation slide blocks (923) inwardly push to realize described frictional fit equally, described in when the lug (812) that described vertical raised line (811) distributes with described horizontal direction does not all engage wedge surface junction surface (9231) of described circular orientation slide block (923), two circular orientation slide blocks (923) make described bellmouth (9230) and described conical section (921) throw off under the effect of corresponding Compress Spring (922).
