When the fitting 2 is unfolded, an external force is applied to the first bearing member 21, the first bearing member 21 is separated from the second bearing member 22 under the action of the external force, and the first bearing member 21 and the second bearing member 22 are in an included angle state. The first bearing member 21 drives the supporting radial arm 13 to rotate relative to the second bearing member 22 through the hinge structure 1, so that the free end 1312 of the supporting radial arm 13 is far away from the second bearing member 22. The free end 1312 extends away from the second carrier 22 to provide a supporting force for the second carrier 22, so as to avoid the phenomenon of toppling when the device body 3 is placed on the first carrier 21 and/or the second carrier 22, and improve the overall stability of the fitting 2.

When the fitting 2 is folded, a force opposite to the above external force is applied to the first carrier 21, so that the first carrier 21 approaches the second carrier 22 to assume a stacked state. The first bearing piece 21 drives the supporting radial arm 13 to rotate relative to the second bearing piece 22 through the hinge structure 1, so that the free end 1312 of the supporting radial arm 13 is close to the second bearing piece 22, the recovery of the supporting radial arm 13 is realized, and the user can conveniently store the accessory 2.

And the first shaft body 222 is formed with a relief portion 2224 communicating with the first receiving groove 2223, the relief portion 2224 being configured to relieve the fourth connection portion 132 supporting the radial arm 13.

In this embodiment, as shown in fig. 9-12, the second carrier 22 further includes at least one second receiving groove 2225, where the second receiving groove 2225 is disposed on the second carrier body 221. The second accommodation groove 2225 is located at the edge of the lower side surface of the second bearing body 221, and in the folded state of the fitting 2, the radial arm body 131 supporting the radial arm 13 can be accommodated in the second accommodation groove 2225, so that the accommodating effect of supporting the radial arm 13 is further achieved.

The number of the second receiving grooves 2225 is related to the number of the supporting radial arms 13, and is based on the design number of the supporting radial arms 13.

In the present embodiment, as shown in fig. 9 and 13, the first carrier 21 includes a first carrier body 211 and at least one second shaft body 212, and the hinge structure 1 is connected to the first carrier body 211 through the corresponding second shaft body 212. The second shaft bodies 212 may be two, for example, symmetrically disposed on two sides of the first bearing body 211, and integrally formed with the first bearing body 211. The first shaft body 222 is located between the two second shaft bodies 212, and the first shaft body 222 is connected with the second shaft bodies 212 through the hinge structure 1.

In this embodiment, as shown in fig. 9 and 13, the first carrier 21 further includes a magnetic attraction body (not shown in the drawings) disposed in the first carrier body 211. When the equipment body 3 is placed on the first bearing body 211, the equipment body 3 can be connected with the first bearing body 211 through the magnetic attraction body, so that stability of the equipment body 3 in use is improved, and dislocation or movement of the equipment body is avoided.

When the accessory is unfolded or folded, the first bearing piece drives the supporting radial arm to rotate through the hinge structure, so that linkage between the first bearing piece and the supporting radial arm is realized, redundant complicated steps are simplified, and the grade of the accessory is improved.

When the accessory is fully unfolded, the free end part of the supporting radial arm extends out of the second bearing body, the free end part extends out of position, a supporting point is provided for the accessory, and the overall stability of the accessory is improved. When the electronic equipment is placed on the second bearing piece and/or the first bearing piece, the gravity center of the accessory is not shifted, so that the accessory is prevented from overturning.

In the unfolding or folding process of the accessory, the damping mechanism in the hinge structure provides damping force for the first bearing piece, so that the first bearing piece can be stopped at any time, and the requirement of a user on the angle of the first bearing piece is met.

In the unfolding process of the accessory, the locking mechanism in the hinge structure prevents the first bearing piece from further moving, when the first bearing piece rotates to a preset angle relative to the second bearing piece, the maximum opening and closing angle of the accessory is reached, and the locking effect of the maximum angle of the accessory is achieved.
