[0023] like Figure 1-Figure 2 As shown, the clamping mechanism 3 includes a first clamping plate 301, a second clamping plate 302 and a clamp 303, and the clamp 303 is respectively fixed on the opposite sides of the first clamping plate 301 and the second clamping plate 302, and grooves are opened in the middle of the opposite sides of the two sets of clamps 303, so as to facilitate the clamps 303 to clamp and fix the workpiece through the first clamping plate 301 and the second clamping plate 302.

[0024] like Figure 1-Figure 2 As shown, the first clamping plate 301 and the second clamping plate 302 are both slidably connected to the support platform 2 , and the first clamping plate 301 and the second clamping plate 302 can be guided by the support platform 2 .

[0025] like Figure 1-Figure 2 As shown, linkage mechanisms 5 are installed on the outside of the first clamping plate 301 and the second clamping plate 302. The linkage mechanism 5 includes two groups of guide rods 501, a top plate 502 and two groups of return springs 503, which facilitate the first clamping plate 301 and the second clamping plate 302 to move synchronously through the linkage mechanism 5.

During use, the movement of the first clamp plate 301 will cause the return spring 503 to contract, and the second clamp plate 302 is pulled to move by the return spring 503.
