DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1 - Figure 2As shown, the utility model provides a tension sensor with a retractable end, including a tension sensor body 1 and a wire 2, the end of the wire 2 is fixedly connected to the end body 3, the bottom of the tension sensor body 1 is fixedly connected to a cable reel 4, the cable reel 4 includes a shell 401, the shell 401 is fixedly installed at the bottom of the tension sensor body 1, a coil spring 402 is installed inside the shell 401, the center position of the shell 401 is rotatably connected to a rotating shaft 403, one end of the coil spring 402 is fixedly installed on the rotating shaft 403, the other end of the coil spring 402 is fixedly installed on the shell 401, the wire 2 is coiled on the rotating shaft 403, at least one group of brushes 404 is installed in the rotating shaft 403, and the wire 2 is electrically connected to the tension sensor body 1 through the brushes 404. According to the shape of the original tension sensor body 1, a cable reel 4 is integrated, and the coil spring 402 inside the cable reel 4 can be used to make the rotating shaft 403 generate a steering force. The wire 2 is electrically connected to the tension sensor body 1 using a brush 404, so the wire 2 can be coiled. Therefore, a longer wire 2 can be set to be coiled in the cable reel 4, and the end body 3 can be pulled out. The length of use can be adjusted by pulling out and can be pulled out to a suitable length.

[0017] A mounting bracket 5 is fixedly mounted on the bottom of the cable reel 4, and a mounting hole 6 is provided on the mounting bracket 5. The mounting hole 6 is provided on the mounting bracket 5 to facilitate installation.

[0018] An opening 7 is provided on one side of the housing 401, and a limiting assembly 8 is provided on one side of the housing 401 located at the opening 7. The wire 2 can be drawn out from the opening 7, and the limiting assembly 8 can be used to limit the wire 2.

A rubber layer 805 is arranged on the rotating member 802. The wire groove 804 on the wire plate 801 can facilitate the sliding of the wire 2. When the wire 2 is pulled out of the housing 401, the wire 2 follows the direction of the rotating member 802, which can facilitate the pulling. When the wire 2 is loosened, the wire 2 is stuck on the rotating member 802, and the rubber layer 805 increases the resistance and prevents the wire 2 from being damaged, and can prevent the wire 2 from being automatically pulled back.

[0020] Working principle: When in use, by pulling the wire 2, the wire 2 can be rotated with the rotating shaft 403, and then the wire 2 can be pulled to a suitable length for use. When the wire 2 is pulled out of the housing 401, the wire 2 follows the direction of the rotating member 802, which can be easily pulled. When the wire 2 is loose, the wire 2 is stuck on the rotating member 802, which can prevent the wire 2 from being automatically pulled back. When the wire 2 needs to be coiled, the rotating member 802 can be pressed to coil the wire 2. Therefore, the wire 2 can be coiled, so that a longer wire 2 can be set to be coiled in the wire reel 4, and the length of use can be adjusted by pulling, and can be pulled to a suitable length.
