In the present embodiment, the sliding opening 211 is oriented in the same direction as the telescopic hole 12. The inner diameter of the telescopic hole 12 is larger than the caliber of the sliding opening 211. The sliding opening 211 is adjacent to the telescoping bore 12. When the sliding member 31 extends out of the telescopic cavity 21 through the sliding opening 211, the sliding member 31 extends out of the telescopic hole 12 relative to the base 10. When the sliding member 31 is partially retracted into the telescopic cavity 21 through the sliding opening 211, a portion of the sliding member 31 exposed from the telescopic cavity 21 covers the telescopic hole 12. Two opposite side walls of the telescopic cavity 21 extend in parallel with the telescopic hole 12, so that the telescopic cavity 21 guides the sliding member 31 in a sliding manner. The slider guide 21 includes a first end 212 near the telescopic hole 12 and a second end 213 opposite to the first end 212. The sliding opening 211 is disposed at the first end 212.

One end of the plurality of steel wires 43, which is far away from the winding shaft 41, is still accommodated in the telescopic cavity 21, so that the plurality of steel wires 43 can be smoothly filled in the telescopic cavity 21 after the winding shaft 41 releases the plurality of steel wires 43 for expansion next time.

Further, referring to fig. 7 and 8, the functional assembly 100 further includes a first elastic member 44, wherein the first elastic member 44 is elastically connected to the sliding member 31 and the sliding guide member 21, and is used for providing an elastic restoring force for the sliding member 31 to contract in the telescopic cavity 21 when the sliding member 31 extends relative to the base 10. The elastic restoring force of the first elastic member 44 is smaller than the urging force of the plurality of wires 43 against the slider 31.

In this embodiment, the peripheral sidewall of the slider 31 is provided with a first hook 314 that exposes the telescopic cavity 21. The outer side wall of the slide guide member 21 is provided with a second hook 315 opposite to the first hook 314 in a direction parallel to the sliding direction of the slide member 31. The second hook 315 is located at an end of the slide guide 21 away from the slide opening 211. One end of the first elastic member 44 is fixedly connected to the first hook 314, and the other end is fixedly connected to the second hook 315. The first elastic member 44 provides an elastic force for the first hook 314 and the second hook 315 to move together. The first hook 314 is disposed on a peripheral side wall of the first sliding end 311. The first hook 314 passes through the inner side wall of the telescopic cavity 11. The sliding member 31 is provided with the first hooks 314 on two opposite side walls. The slide guide member 21 is provided with two second hooks 315 respectively opposite to the first hooks 314. The functional assembly 100 includes two of the first elastic members 44. The two first elastic members 44 exert a tightening force on the sliding member 31 contracting relative to the slide guide member 21, so that the sliding member 31 slides in balance relative to the slide guide member 21. The first elastic member 44 is a rectangular spring. The first elastic member 44 is located outside the flexible cavity 11 to ensure that the first elastic member 44 is independent from the plurality of steel wires 43, so that the plurality of steel wires 43 can be smoothly filled in the flexible cavity 11, and the first elastic member 44 can continuously apply the elastic tension force.

In this embodiment, the second sliding end 312 is exposed to the telescopic cavity 11. The second sliding end 312 is provided with a limiting portion 312 a. The stopper 312a is a flange. When the first elastic element 44 pulls the sliding element 31 to contract in the telescopic cavity 11, the limiting portion 312a abuts against the outside of the sliding opening 211 of the sliding guide member 21. The stopper 312a covers the slide opening 211. A receiving gap 311a exists between the first sliding end 311 and the end of the telescopic cavity 211 far from the sliding opening 311, and the receiving gap 311a is used for receiving a plurality of steel wires 43 and extending out of one end of the winding shaft 41. After the plurality of steel wires 43 are gradually expanded in the receiving gap 311a, the slider 31 is slid in a direction extending out of the expansion chamber 21, and the expansion chamber 21 is gradually filled with the plurality of steel wires 43.

When the first elastic element 44 drives the sliding element 31 to contract in the telescopic cavity 21, the limiting portion 312a slides towards the cushion pad 214 and applies an impact force to the cushion pad 214. The cushion pad 214 has elastic deformation performance, so that the cushion pad 214 can deform under the sliding impact action of the limiting portion 312a, and further absorb the sliding impact of the limiting portion 311 a. The cushion pad 214 can reduce the rigid impact of the limiting portion 312a on the slide guide 21, avoid the slide member 31 from being damaged, and avoid the camera module 32 from vibrating due to the rigid impact, thereby improving the safety.
