Abstract

A device for smooth sliding of a positioning rod of a sawing device platform is disclosed. The device includes a support platform or a lateral side of an auxiliary platform with a calibration rod and a gap is formed between the calibration rod. A support platform or the lateral side of the auxiliary platform. The support platform or the auxiliary platform is flatly mounted with the positioning rod which slides between the support platform and the auxiliary platform. A bottom face of one end of the positioning rod, closer to an operator is provided with an inverted L-shaped corner plate perpendicular to the positioning rod, the end face at the same end of the positioning rod is provided with two parallel wing plates having a distance apart, the top section between the two wing plates is pivotally mounted with a swing plate, whereby when the eccentric wheel and the calibration are urged with each other, the screw nuts of the two auxiliary plates dislocate the urging of the calibration rod thereby enabling the positioning rod to be smoothly moved without forming an eccentric movement.

Claims

1. A device for smooth sliding of a positioning rod of a sawing device platform, characterized in that the support platform or the lateral side of the auxiliary platform is provided with a calibration rod and a gap is formed between the calibration rod and the support platform or the lateral side of the auxiliary platform, the support platform or the auxiliary platform is flatly mounted with the positioning rod which can slide between the support platform and the auxiliary platform, a bottom face of one end of the positioning rod, closer to an operator is provided with an inverted L-shaped corner plate perpendicular to the positioning rod, an end face at the same end of the positioning rod is provided with two parallel wing plates having a distance apart, the bottom face of the positioning rod on the other end is provided with a frictional plate, a top section between the two parallel wing plates is pivotally mounted with a swing plate, the swing plate corresponding to an inner side of the end face of the positioning rod and is urged by a spring connected to the positioning rod, the swing plate is urged by the spring to swing eccentrically outward, a lower section between the two parallel wing plates are pivotally mounted with a control rod, the control rod is mounted with an eccentric wheel, the other end of the control rod is provided with a handle and the eccentric wheel and a lower end of the swing plates are urged together, an external lateral face of the two parallel wing plates are provided with an auxiliary plate having screw holes allowing for insertion of screws, a vertical lateral side of the inverted L-shaped corner plate is inserted into the gap, a horizontal side of the inverted L-shaped corner plate is provided with holes allowing for insertion of screws, a metal plate is welded to the lateral edge of the vertical lateral plate of the corner side corresponding, to a lateral side of the calibration rod and a welding point of the metal plate is located at a middle position thereof, two ends of the metal plate are provided with frictional plates, and the two parallel wing plates of the positioning rod are located on the other lateral side of the calibration rod adjacent to the auxiliary plates, and when the two lateral sides of the calibration rod at the eccentric wheel of the control rod are dislocated, the frictional plate and the screws of the auxiliary plate urge slightly the calibration rod, and when the eccentric wheel and the calibration rod are urged with each other, the screws of the auxiliary plate dislocate urging of the calibration rod.

2. The device of claim 1, wherein the frictional plate of the bottom face of the positioning rod, the frictional plates of the metal plate, the screws on the horizontal side of the corner plate and the screws of the auxiliary plate are made from plastic material.

3. The device of claim 1, wherein a lateral side of the swing plate corresponding to the end face of the positioning rod is provided with a sunken hole at a lower section of the end face of the positioning rod, the spring is inserted into the sunken hole, wherein a screw is inserted into an inner hole of the spring to hold the spring in place.
