Compared with the existing method of adjusting the position of the screw by starting and stopping the motor 1, the present method is more accurate and faster.

[0027] The support 2 is fixedly connected to the top of the transmission box 4, and the motor 1 is connected to the top end of the support 2 through bolts.

[0028] The support assembly comprises a support disc 14, a sleeve 13, a guide rod 3, a spring 10 and a connecting block 11.

[0029] The support disc 14 is arranged in the interior of the support 2, the connecting block 11 is fixedly connected to the outer ring surface of the support disc 14, and the connecting block 11 is slidably connected to the support 2.
