[0029] In order to facilitate control, a middle adjustment groove 9 is opened on the outer side of the main column 1 between the upper top angle adjustment groove 2 and the lower top angle adjustment groove 3, and an external hexagonal control block 10 is coaxially sleeved on the outer side of the internal adjustment screw 4 at the position of the middle adjustment groove 9.

[0030] In order to limit and close the top end of the internal adjustment screw 4, an inner guide groove 11 is opened on the inner top surface of the upper top angle adjustment groove 2 and the inner bottom surface of the lower top angle adjustment groove 3, and an internal thread top guide block 12 is slidably assembled in the inner guide groove 11.

[0031] People change the lifting and lowering of the lateral sliding frame 6 by rotating the internal adjusting screw 4, and then put the internal thread top guide block 12 on the top of the internal adjusting screw 4. While changing the height of the lateral sliding frame 6, the internal thread top guide block 12 is threadedly connected to the top of the internal adjusting screw 4, thereby closing the openings of the upper top angle adjustment groove 2 and the lower top angle adjustment groove 3, maintaining the stability of the internal adjusting screw 4 and the stability of the lifting and lowering adjustment. The position of the lateral sliding frame 6 inside the upper top angle adjustment groove 2 and the lower top angle adjustment groove 3 can be determined according to the time difference of the threaded connection during assembly.
