A first positioning column 1513 is disposed on a surface of the positioning disk 151 close to the second housing 119, and is used for connecting the positioning disk 151 with the turntable 155, so that the elastic member 153 can be reliably accommodated between the positioning disk 151 and the turntable 155, and the elastic member 153 can perform stable elastic rotation motion. The elastic restoring force of the elastic member 153 can make the turntable 155 rotate clockwise around the second fixing post 1191 of the second housing 119.

4. By sliding the limiting member 133 from between the second transition rail 167 and the third transition rail 169 through the third transition rail 169 and into the first rail 161, the external force applied can be removed, so that the connection line slides along the clockwise rotating turntable 155 at the first rail 161 under the elastic restoring force of the elastic member 153, and is accommodated between the first shell 117 and the second shell 119.

5. Through with the track of carousel 155 sets up to the height that the level is different and gradually the gradual transition, has strengthened the gliding adaptability of locating part 133 on the track surface of spacing subassembly 13, the locating part 133 of being convenient for is in the carousel 155 surface can be more smooth and easy slip.

6. Because the surface height of the turntable 155 is different, the limiting member 133 can make a sound when contacting the turntable 155, and can be used for prompting that the stretching of the single-stretching connecting wire 1 is close to the position of the gear, so that the user can judge and select the stretching degree conveniently.

The above is only a preferred embodiment of the present invention, and should not be limited to the present invention, and any modifications, equivalent replacements, and improvements made within the principle of the present invention should be included in the protection scope of the present invention.
