In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a but anchor clamps for quick location, includes the base, fixed surface is provided with two bases on the base, trapezoidal spout has been seted up to the base upper surface, slidable mounting has the slider in the spout, the rectangle mounting groove has been seted up to the relative one side of slider, but install the substitution anchor clamps through the bolt in the rectangle mounting groove, but be provided with circular workstation between the substitution anchor clamps, the work piece has been placed on the workstation, and slider one side is provided with the cam, the cam is installed on the base through the pivot, and one side of cam is provided with the horizontal pole, two through-holes have been seted up to the symmetry on the horizontal pole, and the slider both sides are provided with the boss, install the telescopic link in the boss, the telescopic link runs through boss and horizontal pole, the spring has been cup jointed to the horizontal pole outside.

Furthermore, a handle is arranged on one side of the cam, and the handle plays a role of facilitating operation of a person.

Furthermore, a layer of rubber sleeve is sleeved at the tail end of the grip and plays a role in increasing friction force.

Furthermore, the cam is positioned between the sliding block and the cross rod, and two sides of the cam are respectively contacted with the sliding block and the cross rod.

Furthermore, the middle of the workbench is marked with a central point through paint.

Furthermore, the rectangular mounting groove is L-shaped, and the clamp can be detached and replaced according to different workpieces, so that the device is suitable for workpieces in various shapes, and the application range of the device is expanded.

The utility model has the advantages that: through the cam that this scheme provided, mutually support between slider and the telescopic link, the cam comprises two identical semicircles, consequently, the gliding distance of two sliders is the same, the slider is at last in workstation center department and assembles, the slider removes the in-process and promotes the work piece and remove to the center, it only possesses clamping function to have solved ordinary anchor clamps, can not fix a position work piece center, still need artifical adjustment work piece position to aim at the problem of central point sometimes, this device simple structure, and convenient for operation can realize central locate function at the centre gripping in-process, the artifical once more location has been avoided, and the machining efficiency is greatly improved.
