[0030] Refer to Figure 2The adjusting mechanism 4 includes a moving block 42, one end of the moving block 42 is slidably fitted with one end of the support frame 2, and both sides of one end of the support frame 2 are rotated together and connected with a screw rod 41, the outer surface of the screw rod 41 is socketed with the inner wall of the moving block 42, and one end of the support frame 2 is fixedly installed with a guide rail 21, and the inner wall of one end of the moving block 42 is slidably fitted with the outer surface of the guide rail 21, and one end of the support frame 2 is fixedly installed with a first motor 47, and the output end of the first motor 47 is fixedly connected to one end of the screw rod 41, and the screw rod 41 can be driven to rotate by the output of the first motor 47. The rotating screw rod 41 drives the moving block 42 to perform horizontal threaded movement, and with the help of the guide rail 21, a relatively stable sliding support is provided for the movement of the moving block 42, thereby ensuring the smooth movement of the moving block 42.
