the utility model provides a machined part fastener, includes the brace table that location platform and side set up, the brace table top is equipped with the propelling movement component, propelling movement component push rod level is towards the location platform, the brace table rotates through the hinge and is equipped with the tight piece of clamp that corresponds with the location platform, press from both sides tight piece at the perpendicular to the hinge direction is equipped with the waist hole, waist hole slope sets up, and its front end is higher than the rear end, the waist hole matches the slip and is equipped with the slider, slider and propelling movement component's push rod is connected.

Furthermore, a pressure head structure protrudes from the bottom surface of the front end of the clamping block.

Furthermore, the clamping block is of a U-shaped structure and comprises a clamping portion and two connecting portions, wherein the clamping portion corresponds to the positioning table, the two connecting portions are arranged at the rear end of the clamping portion in an aligned mode, the two waist holes are symmetrically formed in the two connecting portions, and the sliding piece is of a shaft structure which is connected between the two waist holes in a sliding mode.

Further, the pushing element is a cylinder.

Compared with the prior art, a machined part fastener have following advantage:

the utility model discloses simple structure, it is with low costs, press from both sides tight piece through sliding in the waist hole slide the slider line connection cylinder push rod that sets up on, drive through the cylinder and press from both sides tight piece around its hinge upset, realize the quick clamp of work piece tight, improve work piece clamping efficiency.
