The first locking assembly penetrates through the top end surface of the rotary housing 101, and a part of the first locking assembly can move to the position of the fixed tube 106 and finally abuts against the top of the fixed tube 106.
In this embodiment, the first locking assembly includes a first locking knob 103 and a top block 104, the top block 104 is located inside the rotary housing 101, a part of the first locking knob 103 is located outside the rotary housing 101, and another part of the first locking knob 103 is connected to the top block 104 after penetrating through a center position of a top end surface of the rotary housing 101.
After the first locking knob 103 is connected with the top block 104, the top block 104 can be driven to move to a position close to the fixed pipe 106 or a position far from the fixed pipe 106 by rotating the first locking knob 103 clockwise or anticlockwise. When the top block 104 abuts against the fixed tube 106, the fixed tube 106 can be locked in the rotary case 101, and at this time, the fixed tube 106 cannot be moved. When the top block 104 is moved to a position away from the fixed tube 106, the fixed tube 106 is changed from the locked state to the active state, and the fixed tube 106 can be rotated inside the rotary case 101.
The fixed pipe 106 is sleeved outside the limiting shaft 105, the fixed pipe 106 and the limiting shaft 105 are coaxially arranged, and the axis of the fixed pipe 106 is coincident with the axis of the limiting shaft 105.
