The knob 6 is a spherical knob.

[0019] The base 3 is a "T"-shaped block, and its upper part is parallel to the protruding surface of the screw 1 and connected to the pointer 21.

The cross section of one end of the first stepped shaft 18 is larger than the through hole, and the other end is threadedly connected with the first adjustment handle 9. The first adjustment handle 9 is rotated to loosen the rotating block 8 and the shaft support 7, so that the rotating block 8 rotates around the first stepped shaft 18, and the first adjustment handle 9 is tightened to fasten the rotating block 8 to the shaft support 7.
