[0037] When using, Figure 3As shown, the workpiece to be clamped is inserted into the positioning block 2; through the inclined slope of the push-pull block 6 and the inclined platforms of the left and right pressure blocks 4 and 5, they are squeezed against each other under the action of thrust, thereby achieving the clamping and positioning of the workpiece to be clamped.

[0038] like Figure 6 The structure diagram of the positioning block, Figure a is a left view, Figure b is a main view, Figure c is a top view, and Figure d is a three-dimensional structure diagram; the positioning block 2 is installed on the bottom plate 1 by screws, and the periphery of the positioning block 2 is provided with screw holes for screws; the positioning block 2 is a concave structure, and a characteristic groove for positioning the workpiece to be clamped is processed on the positioning block 2, and the clamped workpiece is inserted in the characteristic groove, and the contour structure of the characteristic groove matches the contour structure of the clamped workpiece; the characteristic groove can be adjusted to the most suitable structure according to the specific shape of the workpiece to be used, and the utility model does not make any special limitation on the structure of the characteristic groove;

[0039] The positioning block 2 is also processed with a square groove for positioning the left pressing block 4 and the right pressing block 5, and the left pressing block 4 and the right pressing block 5 can slide up and down in this groove; the inner contour shape of the square groove matches the contour structure of the left pressing block 4 and the right pressing block 5, and is symmetrically arranged on both sides of the positioning block 2. In a preferred embodiment, the characteristic groove is located in the middle part of the positioning block 2, and the square grooves are located on both sides of the characteristic groove, which is convenient for positioning the clamped workpiece;

[0040] like Figure 1 As shown, the base plate 1 is located directly below the left pressure block 4 and the right pressure block 5 and is processed with two mounting holes for placing the compression spring 3. The compression spring 3 is used to push the left pressure block 4 and the right pressure block 5 upward when loosened; the connecting block 8 is installed on the base plate 1 by screws, and the connecting block 8 is processed with a threaded hole matching the pull rod 7, and the free end of the pull rod 7 is installed with a handle 10; the handle 10 is fixedly connected to the pull rod 7 by a cylindrical pin 9.

[0041] like Figure 7 As shown, the push-pull block 6 has two branches, and the front end of the lower surface of each branch is processed with a slope, which cooperates with the inclined platform at the lower end of the left pressing block 4 and the right pressing block 5 to achieve alignment.
