The rear end side of the arm 1 is rotationally connected with the fixed plate 10. The buckle seat 2 is fixedly arranged on the fixed plate 10. The rear end side of the arm 1 is rotationally connected with the fixed plate 10 through a shaft 11. Rotating the arm 1 can make the other side of the rear end of the arm 1 approach or move away from the buckle seat 2. When approaching the buckle seat 2, the locking part 4 can be buckled on the buckle seat 2 through the buckle part 3 to realize the unfolding and fixing of the arm 1. When moving away from the buckle seat 2, the folding and storage of the arm 1 are realized.

[0027] For details Figure 3 And 4, the locking piece 4, the buckle adjusting pivot 5 and the bolt 6 are arranged on the buckle piece 3, one end of the buckle adjusting rod 8 is perpendicularly and threadedly connected with the buckle adjusting pivot 5, the other end is perpendicularly connected with the buckle pivot 7, the buckle pivot 7 is also rotationally arranged on the arm 1, when the other side of the rear end of the arm 1 approaches the buckle seat 2, the buckle piece 3 is moved to make the locking piece 4 buckled in the buckle seat 2, since one end of the buckle adjusting rod 8 is perpendicularly and threadedly connected with the buckle adjusting pivot 5, the distance between the locking piece 4 and the buckle seat 2 can be lengthened or shortened by adjusting the depth of the thread connection of the buckle adjusting rod 8, thereby the connection tightness of the arm 1 and the buckle seat 2 is changed, the arm 1 is more tightly connected without gap, and the rigidity of the arm 1 is greatly improved. Meanwhile, the buckle piece 3 is pressed, the buckle piece 3 rotates around the locking piece 4, the arm 1 is close to the buckle seat 2, and the bolt 6 can be inserted into the arm 1 through the insertion slot 101 on the arm 1, and the locking and fixing of the arm 1 and the buckle seat 2 are completed through the insertion of the bolt 6 into the arm 1.

[0028] In the embodiment, the buckle seat 2 is of C-shaped structure, the locking piece 4 is a locking pin shaft, and fastening connection is realized by clamping the locking pin shaft in the C-shaped slot of the buckle seat 2. The bolt 6 is a spring self-locking bolt, and can automatically pop out and be inserted into the insertion slot 101 after being aligned with the insertion slot 101. The buckle piece 3 is provided with a buckle handle 301, and the buckle piece 3 is convenient to move.

[0029] Working principle:

[0030] When the arm 1 is unfolded, the arm 1 is rotated to make the other side of the rear end approach the buckle seat 2, then the buckle piece 3 is moved to make the locking piece 4 buckled in the buckle seat 2, then the buckle handle 301 is pressed to make the buckle piece 3 rotate around the locking piece 4, the arm 1 is close to the buckle seat 2, and the bolt 6 is inserted into the arm 1 through the insertion slot 101 on the arm 1.

[0031] When the arm 1 is folded, the bolt 6 is pulled out from the insertion slot 101 on the arm 1, then the buckle handle 301 is pulled to make the buckle piece 3 rotate around the locking piece 4, until the locking piece 4 is separated from the buckle seat 2, finally the arm 1 is rotated to make the other side of the rear end away from the buckle seat 2, and the folding is completed.

[0032] The above is only a specific implementation manner of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
