The adjusting button 53 can slide up and down along the through slot 31 of the housing 3 and the through hole 411 of the support 41 on the base 4. When the adjustment button 53 is located at the top, the adjustment button 53 abuts against the top fixing groove 544 of the adjustment block 54, i.e. the top end of the chute. The adjusting button 53 presses the adjusting block 54, the adjusting block 54 is connected and fixed with the movable member 52 through self-tapping screws, and the two springs 55 are pressed through the movable member 52. At this time, the first limiting block 541 on the adjusting block 54 is clamped in the first limiting groove 91 on the fixing pin 9 of the bottom 2, and the second limiting block 542 is clamped in the second limiting groove 92. The top part 1 can be rotated, but because the first limit groove 92 has a length of only half the circumference of the fixing pin 9, the top part 1 can be rotated 180 ° from the bottom part 2.

When the adjustment knob 53 is slid down to the middle, the adjustment knob 53 now abuts against a middle fixing groove 544 on the adjustment block 54, i.e. the middle of the chute. Under the action of the elastic forces of the two springs 55, the movable element 52 is biased outwards, and at the same time, the adjusting block 54 is driven to be biased outwards. At this time, the first limiting block 541 on the adjusting block 54 is not clamped in the first limiting groove 91 on the fixing pin 9 of the bottom 2, and the second limiting block 542 is clamped in the second limiting groove 92. The top part 1 can rotate, and because the length of the second limiting groove 92 is equal to the circumference of the fixing pin 9, the top part 1 and the bottom part 2 can rotate 360 degrees.

When the adjustment button 53 is slid down to the lowermost position, the adjustment button 53 now abuts against the lower fixing groove 544 on the adjustment block 54, i.e. the lowermost end of the chute. Under the elastic force of the two springs 55, the movable element 52 deflects outward, and at the same time, drives the adjusting block 54 to deflect outward. At this time, the first limiting block 541 on the adjusting block 54 is not clamped in the first limiting groove 91 on the fixing pin 9 of the bottom 2, and the second limiting block 542 is not clamped in the second limiting groove 92. The connection limit between the top part 1 and the bottom part 2 is released, and the top part 1 and the bottom part 2 are separated.

When the device is installed, the position of the nut 562 on the shaft 561 is adjusted, so that the tightness between the cylinder 563 and the shaft 561 is adjusted. When the nut 562 rotates downwards and is loosened, the cylinder 563 can rotate around the shaft 561, and the bottom can rotate in a corresponding angle. When the nut 562 rotates upwards to press the axle 561 and the cylinder 563, the cylinder 563 cannot rotate freely; because the positioning rod 93 on the fixing pin 9 on the bottom 2 is clamped in the arc-shaped groove 564 on the cylinder 563, the bottom 2 cannot rotate freely in a corresponding angle, and the angle is fixed. When the rotation angle is required, the cylinder 563 and thus the bottom 2 can be loosened by adjusting the nut 562, thereby achieving the rotation adjustment.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
