[0023] Further, one end of the reinforcing rib 12 is fixedly connected to one side of the support plate 11, and the other end of the reinforcing rib 12 is fixedly connected to the top of the workbench 1. The supportability of the support plate 11 is strengthened through the reinforcing rib 12, so that the stability of the support plate 11 is improved.

[0024] Further, the motor 22 is fixedly connected to the top of the fixed seat 21 through the fixed bolt 23, and the driving shaft of the motor 22 is fixedly connected to the rotating shaft 24. When the motor 22 is turned on, the motor 22 drives the rotating shaft 24 to rotate, the rotating shaft 24 drives the fixed plate 25 to rotate, and the angle of the clamping plate 5 changes.

[0025] Further, the upper and lower sides of the support rod one 41 are provided with sliding grooves 42, and the upper and lower sides of the support rod two 45 are fixedly connected with sliding rods 46 which slide left and right in the sliding grooves 42.
