The locking device of the support of the embodiment is very simple to operate, and can realize quick locking and unlocking.

[0053] Of course, when the matching inclined surface 211 is arranged on the inner wall of the receiving cavity 111, the blocking strip 112 is arranged on the rotating piece 2, and the blocking strip 112 slides along the matching inclined surface 211 and rotates with the rotating piece 2.

[0054] Reference Figure 5 With Figure 6The first shell 1 comprises a top cover 10 and a middle cylinder 11 connected to the top cover 10, and a containing cavity 111 arranged in the middle cylinder 11.

[0055] The containing cavity 111 is arranged along the axial direction of the middle cylinder 11 and is a circular cavity, and the rotating member 2 can move axially in the containing cavity 111 or rotate in the containing cavity 111. One end of the containing cavity 111 penetrates the end surface of the middle cylinder 11, and the other end is located in the interior of the middle cylinder 11. Two blocking strips 112 are further arranged on the side wall of the containing cavity 111, and the two blocking strips 112 are respectively located at the two radial ends of the containing cavity 111. In the embodiment, the blocking strips 112 are cylindrical, and the axial direction of the blocking strips 112 is perpendicular to the axial direction of the containing cavity 111.

[0056] The containing cavity 111 is used for containing the rotating member 2, and the rotating member 2 comprises a first block 20 and a second block 21. The upper end surface of the first block 20 and the lower end surface of the second block 21 are connected and located on the same axial direction. The first block 20 and the second block 21 are both cylindrical in shape, so as to be matched with the circular containing cavity 111.

[0057] The upper end surface of the first block 20 is provided with a limiting groove 201, which is located at the middle part of the first block 20 and is arranged along the axial direction of the first block 20. One end of the elastic member 3 is inserted into the limiting groove 201, and the other end of the elastic member 3 is connected with the bottom wall of the containing cavity 111. When an external force pushes the first block 20 to move to the side of the bottom wall of the containing cavity 111, the elastic member 3 is compressed. When the external force is removed, the elastic force of the elastic member 3 pushes the first block 20 to move away from the bottom wall of the containing cavity 111, so as to reset the first block 20. The elastic member 3 can be a spring or other elastic component.

[0058] Continuing to refer to Figure 4 In the embodiment, a blocking ring 202 is further arranged on the circumferential outer wall of the first block 20.

The blocking ring 202 protrudes from the outer wall of the first block 20, and the lower part of the blocking ring 202 is provided with a circular and inclined arc surface, which extends along the axial direction of the circumferential outer wall of the first block 20, so as to clamp the blocking strips 112. In the embodiment, the number of the inclined arc surfaces is four, and the four inclined arc surfaces are sequentially connected in a head-to-tail manner.

[0059] The outer wall of the second block 21 is provided with four matching inclined surfaces 211, which are sequentially connected end to end, surround one circumference of the second block 21, extend axially along the outer wall of the second block 21, are opposite to the inclined arc surfaces of the first block 20, are staggered with the inclined arc surfaces, one inclined arc surface is opposite to two matching inclined surfaces 211, and the extending directions of the matching inclined surfaces 211 and the inclined arc surfaces are opposite, so that the rotation direction of the blocking strip 112 driving the first block 20 is consistent with the rotation direction of the second block 21.

[0060] When the blocking strip 112 is separated from the first inclined arc surface by using external force, the blocking strip 112 is connected with and slides on the matching inclined surface 211 below the first inclined arc surface, the blocking strip 112 drives the second block 21 to rotate 90°, when the external force is removed, the elastic member 3 pushes the first block 20 to move downward to reset, the blocking strip 112 is separated from the matching inclined surface 211 and is connected with the end of the second inclined arc surface again, the blocking strip 112 slides to the locking position of the second inclined arc surface, and the blocking strip 112 drives the second block 21 to rotate 90°; repeating the process can unlock or lock the buckle block 212 with the buckle groove 412. It should be noted that the junctions of the four matching inclined surfaces 211 can be smoothly and continuously connected in an arc surface.

[0061] The lower part of the second block 21 is provided with a buckle block 212 for buckling with the buckle groove 412, and the moving direction of the buckle block 212 is in the same straight line as the elastic force direction of the elastic member 3.
