One of the first and second pipe sections 1, 2 is connected to the locking mechanism 3 and cannot rotate relatively, and the other can be locked or separated from the locking mechanism 3. When the locking mechanism 3 is locked with the first pipe section 1 or the second pipe section 2, the first pipe section 1 and the second pipe section 2 are relatively fixed, and when the locking mechanism 3 is separated from the first pipe section 1 or the second pipe section 2, the first pipe section 1 and the second pipe section 2 can relatively rotate.

Fig. 1 to 5 show a schematic structural view of the locking mechanism 3 locked and separated with the second pipe section 2. Of course, it is obvious to those skilled in the art that the locking mechanism 3 can be locked and separated with the first pipe section 1 to achieve substantially the same function.

The fixed seat 31 is connected with the first pipe section 1, and the first pipe section 1 is provided with a guide structure which limits the fixed seat 31 to move only along the axial direction of the rotating shaft mechanism 5, but can not rotate in the radial direction, that is, when the first pipe section 1 and the second pipe section 2 rotate relatively, the fixed seat 31 is kept static relative to the first pipe section 1.

In some embodiments, the guiding structure may be a sliding groove extending along the axial direction of the rotating shaft mechanism 5 and a sliding block fitted in the sliding groove, or a guiding hole opened along the axial direction of the rotating shaft mechanism 5 and a guiding column fitted in the guiding hole, or other conventional guiding structures that can be thought of by those skilled in the art. Taking the example that the fixed seat 31 is connected with the first pipe section 1, if the guiding mechanism is a sliding chute and a sliding block, one of the sliding chute and the sliding block is arranged on the fixed seat 31, and the other is arranged on the first pipe section 1; if the guiding mechanism is a guiding post in a guiding hole, one of the guiding hole and the guiding post is arranged on the fixed seat 31, and the other is arranged on the first pipe section 1.

The locking teeth 311 are uniformly distributed along the axial direction of the fixing seat 31, and the positions of the tooth slots 201 and the locking teeth 311 are arranged correspondingly.

As shown in fig. 3 to 5, the locking mechanism 3 further comprises a first elastic device 32, by means of which first elastic device 32 the locking tooth 311 can be preloaded in the tooth slot 201. The first elastic device 32 may be a spring sheet or a compression spring, and one end of the first elastic device 32 is connected to or abutted against the fixing seat 31, and the other end is connected to the rotating shaft mechanism 5, and applies an elastic pressure to the fixing seat 31 in the direction of the tooth slot 201 to preload the locking tooth 311 in the tooth slot 201.

It will be appreciated by those skilled in the art that a plurality of locking teeth 311 may be disposed at the end of the first pipe segment 1 or the end of the second pipe segment 2, and a plurality of tooth slots 201 may be disposed at the fixing seat 31, so that the fixing seat 31 can be locked with the first pipe segment 1 or the second pipe segment 2, and will not be expanded in detail herein.

In the present embodiment, the number of the locking teeth 311 and the tooth grooves 201 is eight, and the eight locking teeth 311 and the tooth grooves 201 are uniformly distributed in the circumferential direction. In principle, the first pipe section and the second pipe section can rotate in the circumferential direction of 360 degrees, and in a practical application scenario, a limiting mechanism is arranged between the first pipe section and the second pipe section to prevent the first pipe section and the second pipe section from rotating in a transition mode. As shown in fig. 7 to 11, the locking angles of the first pipe section 1 and the second pipe section 2 include 90 °, 135 °, 180 °, 225 °, and 270 °.

The release mechanism 4 comprises a release lever 41, which release lever 41 can be arranged on the first pipe section 1 and is movable in the axial direction of the first pipe section 1. When the release mechanism 4 is in the first position, the release rod 41 is disengaged from the fixed seat 31; when the release mechanism 4 moves to the second position under the action of an external force, the release lever 41 extends into the fixed seat 31 and between the first pipe segment 1 and the second pipe segment 2 locked with the fixed seat 31, and applies a pushing force to the fixed seat 31, so that the fixed seat overcomes the elastic force of the first elastic device 32 to move along the axial direction of the rotating shaft mechanism 5, and the locking of the fixed seat on the second pipe segment 2 is released.
