In this embodiment, when the connecting seat 232 is located at the first position, the arm 20 is located at the unfolding state, and when the connecting seat 232 is located at the second position, the arm 20 is located at the folding state.

The cam structure of the clutch part is matched with the first elastic element 234, so that when the horn 20 rotates to the first position and the second position, the horn moves to the first position or the second position automatically through the elastic force of the first elastic element 234, the folding or unfolding efficiency is high, and the experience effect of a user is improved.

Optionally, a cam structure is arranged on one side of the first clutch part 235, which is engaged with the second clutch part 236, and includes a first protrusion 2351 and a first recess 2352 which are arranged on the first clutch part 235, and a cam structure is also arranged on one side of the second clutch part 236, which is engaged with the first clutch part 235, and includes a second protrusion 2361 and a second recess 2362 which are arranged on the second clutch part 236, and when the connecting seat 232 is located at the first position or the second position, the first protrusion 2351 is engaged with the second recess 2362, and the second protrusion 2361 is engaged with the first recess 2352; when the contact point of the first clutch portion 235 and the second clutch portion 236 reaches the highest point of the cam structure, the first protrusion 2351 abuts against the second protrusion 2361. Cam structures are arranged on the two clutch parts, so that the rotation of the connecting seat 232 (namely the rotation of the machine arm 20) is more stable and smooth.

Specifically, the first protrusion 2351 is matched in shape with the second recess 2362 so that the first protrusion 2351 can be just accommodated in the second recess 2362, the second protrusion 2361 is matched in shape with the first recess 2352 so that the second protrusion 2361 can be just accommodated in the first recess 2352, so that the first clutch part 235 is engaged with the second clutch part 236 under the action of the first elastic element 234 and is stationary relative to the second clutch part 236, and the connecting seat 232 is located at the first position or the second position at rest, namely, the machine arm 20 is located at the unfolded state or the folded state so as to limit the machine arm 20, and the machine arm 20 is locked at the unfolded state or the folded state.

When the arm 20 is rotated relative to the body 10, an external force is applied to the arm 20 to rotate the arm 20 by the external force, the two second clutch portions 236 are driven by the arm 20 to rotate synchronously, and the two first clutch portions 235 are defined in the pivot portion 2312, so that the two second clutch portions 236 rotate relative to the first clutch portions 235 under the driving of the rotational force of the arm 20, the first protrusions 2351 are disengaged from the second recesses 2362 and slide to the second protrusions 2361 slowly, and thus the two first clutch portions 235 move in the pivot hole 2310 along the axial direction to continue to compress the first elastic element 234. When the first protrusion 2351 of the first clutch part 235 rotates to the highest point of the second protrusion 2361, the first elastic element 234 is compressed to an extreme position, and the first clutch part 235 continues to rotate relative to the second clutch part 236, at this time, the external force applied to the arm 20 is removed, and the arm 20 can be automatically folded or unfolded to another position under the elastic force of the first elastic element 234.
