In this embodiment, when the rotating handle 532 drives the rotating shaft 150 to rotate forward, the screwed part of the rotating shaft 150 and the screw sleeve 160 will decrease, that is, the vacant area of the rotating shaft 150 will increase. Therefore, the third elastic member 531 can drive the second gear disk 520 to slide on the rotating shaft 150 to move away from the first gear disk 510 to achieve unlocking. At this time, the angle of the connecting head 200 can be adjusted. When the rotating handle 532 drives the rotating shaft 150 to rotate reversely, the screwed part of the rotating shaft 150 and the screw sleeve 160 will increase, that is, the vacant area of the rotating shaft 150 will decrease. Therefore, the second gear disk 520 slides on the rotating shaft 150 under the push of the rotating handle 532 to move close to the first gear disk 510 to achieve meshing and locking.
