[0023] In this embodiment, first, the motor one 201 of the first adjusting structure 2 drives the bidirectional screw one 202 to rotate in the middle groove 12, so that the two moving blocks one 203 move in the middle groove 12 in the same direction or opposite directions according to the size of the front subframe, thereby driving the two second adjusting structures 3 to move synchronously, then the second adjusting structure 3 is adjusted according to the size of the front subframe, and then the clamping mechanism 4 is clamped and fixed, thereby facilitating subsequent machining and processing of the front subframe.

[0024] In an optional embodiment, the second adjusting structure 3 comprises an adjusting frame 301 fixed on the upper end of the moving block 203, the adjusting frame 301 is arranged on the upper end of the clamp seat 1, and a motor 303 is arranged on the outer wall of one end of the adjusting frame 301, the output end of the motor 303 extends into the adjusting frame 301 and is fixedly connected with a bidirectional screw rod 304, the two ends of the bidirectional screw rod 304 are threadedly connected with a moving block 305, the moving block 305 is slidingly arranged in the adjusting frame 301, and the upper end of the moving block 305 is fixedly connected with a fixed block 306, the opposite ends of the two fixed blocks 306 are symmetrically provided with clamping grooves 307, and a clamping mechanism 4 is arranged in the clamping grooves 307.

[0025] It should be noted that the motor 303 of the second adjusting structure 3 drives the bidirectional screw rod 304 to rotate in the adjusting frame 301, so as to drive the moving block 305 to move in the adjusting frame 301 according to the size of the front subframe in a synchronous or opposite direction, and when the position adjustment is completed, the front subframe is clamped at the corner by the clamping mechanism 4 in the clamping groove 307, so as to fix the front subframe.
