Supporting rod on be arranged with compressed spring, the upper end of the compressed spring is fixedly connected with the pressing plate, lower end and the pedestal
It is fixedly connected, the upper end of the supporting rod is rotatably connected to cam, and the lug boss of the cam has vertical plane and cambered surface, described
Vertical plane is located at the direction that rotates counterclockwise of the cam, and the cambered surface is located at the direction that rotates clockwise of the cam, described
Fixed block is equipped with the groove with the raised portion fits of the cam, and the left end of the pressing plate is equipped with to push against supporting for workpiece
Block, the right end of the pressing plate are equipped with the axis pin vertical with the pressing plate, set by the axis pin and corresponding position on the pedestal
Block offsets, and what the block was located at the axis pin rotates clockwise direction.
Further, in above-mentioned technical proposal, the cam is equipped with handle.
Further, step of the opening towards the axis pin is set in above-mentioned technical proposal, on the block.
Further, in above-mentioned technical proposal, the top of the supporting rod is equipped with nut, the nut and the cam
Upper surface is rotatably assorted.
Advantageous effect possessed by the utility model：Since the upper end of supporting rod is rotatably connected to cam, the protrusion of cam
Portion has vertical plane and cambered surface, and cambered surface is located at the direction that rotates clockwise of cam, and fixed block is equipped with matches with the lug boss of cam
The groove of conjunction, by rotating clockwise for cam, the lug boss on cam gradually removes groove set on fixed block, and cam turns
A degree of rotating clockwise with regard to pressing plate can be driven while dynamic, until set on the axis pin and pedestal set by pressing plate right end
Block offset, pressing plate is in the position for clamping workpiece, and at this time without exerting a force to cam, cam is kept and the abutting shape of fixed block
State has the characteristics that clamping effect is good and self-locking performance is strong；When cam rotates backward, since vertical plane is located at the counterclockwise of cam
Rotation direction, the lug boss stent on cam sticks into the groove on fixed block and the counter motion with dynamic pressure plate, realizes simultaneously
The rising of pressing plate and counter-clockwise swing realize the separation of pressing plate and workpiece, have the characteristics that dismounting is convenient.
