It has been widely used in different production fields. In my country, the integration of measurement and processing is increasingly used in the manufacturing field, and the requirements for matching clamping are getting higher and higher. There are existing devices that use flat-nose pliers and magnetic clamping tools to clamp CMM, but flat-nose pliers clamping cannot achieve the expected effect when there are special direction requirements during repeated positioning and product testing.

[0021] like Figure 2 As shown, in the present disclosure, the flat-nose pliers assembly 1 includes a base 11, a fixed clamp 12, a mounting plate 13, a rotating rod 14, a threaded rod 15, a sliding clamp 16, a sliding rod 17 and a handle 18, wherein the fixed clamp 12 is fixedly connected to the top of one side of the base 11, the mounting plate 13 is fixedly connected to the top of the other side of the base 11, the rotating rod 14 is rotatably sleeved on the inner side of the mounting plate 13 and passes through the mounting plate 13, one end of the threaded rod 15 is fixedly connected to the rotating rod 14 and the other end is rotatably connected to the fixed clamp 12 through a bearing, the sliding clamp 16 is threadedly sleeved on the outside of the threaded rod 15, the sliding rod 17 is fixedly connected between the mounting plate 13 and the fixed clamp 12 and is located below the threaded rod 15, and the handle 18 is fixedly connected to the outside of the rotating rod 14.

[0022] Therefore, the operator first places the clamping mechanism 2 between the fixed clamping plate 12 and the sliding clamping plate 16, and then rotates the handle 18. The rotation of the handle 18 drives the rotating rod 14 to rotate. The rotation of the rotating rod 14 drives the threaded rod 15 to rotate. The rotation of the threaded rod 15 drives the sliding clamping plate 16 to slide on the sliding rod 17 until the fixed clamping plate 12 and the sliding clamping plate 16 are in contact with the surface of the clamping mechanism 2 and are stably clamped.

[0023] like Figure 3As shown, in a preferred embodiment, the clamping mechanism 2 includes an assembly chuck 21, a flat-jaw clamping force block 22, an elastic yielding groove 23, a chuck hook 24, a replaceable chuck 25, a hook groove 26 and a product clamping groove 27, wherein the flat-jaw clamping force block 22 is fixedly connected to the outer side of the assembly chuck 21, the elastic yielding groove 23 is opened on the surface of the assembly chuck 21 and passes through the assembly chuck 21, the chuck hook 24 is fixedly connected to the top of the assembly chuck 21, the hook groove 26 is opened on the surface of the replaceable chuck 25 and passes through the replaceable chuck 25, the replaceable chuck 25 is clamped on the top of the chuck hook 24 through the hook groove 26, and the product clamping groove 27 is opened on the top of the replaceable chuck 25 and passes through the replaceable chuck 25.

[0025] Therefore, the operator clamps the flat-nose pliers clamping force block 22 with flat-nose pliers and then installs the replaceable chuck 25 above the chuck hook 24 through the hook slot 26, and then places the product component 3 above the product clamping slot 27 through the product clamping slot 27, and connects the product body 31 with the replaceable chuck 25 through the product flange 32. At this time, the operator turns the handle 18 again, and through the fixed clamp 12 and the sliding clamp 16, the elastic yielding slot 23 is squeezed to stably clamp the product body 31 above the replaceable chuck 25, and then subsequent inspection operations can be carried out.
