[0019] The following is in conjunction with the appendix Figures 1-5The present invention will be described in further detail below.

[0020] Example 1: This example provides a torsion spring clamping and limiting device, such as... Figures 1-5 As shown, it includes a base 1, a limiting component 2 connected to the top of the base 1, a bottom component 3 connected to the limiting component 2, the limiting component 2 is used to limit and fix the bottom component 3, a lifting component 4 connected to the top of the base 1, a cover component 5 connected to the lifting component 4, the lifting component 4 is used to drive the cover component 5 to rotate accurately.

[0021] The limiting component 2 includes a support groove 201 located at the center of the top of the base 1. A limiting through groove 202 is provided inside the support groove 201. A symmetrical sliding through groove 203 is provided through the base 1. A sliding column 204 is slidably connected to the inner wall of the sliding through groove 203. A sliding member 205 is connected to the top of the sliding column 204. The bottom of the sliding member 205 is slidably connected to the top of the base 1. A threaded bracket 207 is connected to the top of the base 1. A threaded rod 206 is threadedly connected to the threaded bracket 207. The threaded rod 206 is rotatably connected to the side of the sliding member 205. An arc-shaped limiting component 208 is connected to the other side of the sliding member 205 away from the threaded rod 206. The arc-shaped limiting component 208 clamps and fixes the outer arc surface of the bottom shell 301, thereby achieving the limiting and fixing effect of this device.

[0022] The bottom component 3 includes a bottom housing 301 that contacts the bottom of the inner wall of the support groove 201. The bottom of the inner wall of the bottom housing 301 has a through hole. A torsion spring 302 is provided inside the bottom housing 301. One end of the torsion spring 302 passes through the through hole at the bottom of the inner wall of the bottom housing 301 and through the interior of the limiting through groove 202. A connecting ring 303 is connected to the outer arc surface at the top of the bottom housing 301. The connecting ring 303 has an arc-shaped through groove 304. A limiting post 305 is slidably connected to the inner wall of the arc-shaped through groove 304. A threaded knob 306 is threadedly connected to the top and bottom of the limiting post 305. The combination of the connecting ring 303 and the docking ring 503 can improve the stability of the relative rotation between the top and bottom of the device.

[0023] The specific working principle is as follows: This device can wrap the torsion spring 302 with a shell structure, while realizing the elastic rotation effect of the upper and lower shell structures relative to each other. Compared with the traditional device, this device can accurately dock and fix one end of the torsion spring 302, thereby driving the torsion spring 302 to rotate through the through groove, and storing the elastic rotational potential energy inside the torsion spring 302, thereby adjusting the rotational resistance between the cover shell 501 and the bottom shell 301.

[0024] Example 2: This example provides a torsion spring clamping and limiting device, such as... Figures 1-5As shown, the lifting component 4 includes an electric lifting telescopic rod 401 connected to the top of the base 1. The top telescopic end of the electric lifting telescopic rod 401 is connected to a lifting plate 402. The top of the lifting plate 402 is rotatably connected to a rotating electric telescopic rod 403. The telescopic end of the rotating electric telescopic rod 403 is rotatably connected to a rotating connector 404. The lifting plate 402 is vertically rotatably connected to a connecting shaft. The top of the connecting shaft is connected to a rotating rod 405. The end of the rotating rod 405 away from the connecting shaft is rotatably connected to the rotating connector 404. The bottom of the connecting shaft is connected to a transmission housing 406. The inner arc surface of the transmission housing 406 is provided with a transmission groove 407.

[0025] The cover component 5 includes a cover housing 501 disposed inside the transmission housing 406. The outer arc surface of the cover housing 501 is provided with a transmission protrusion 502. The outer side of the transmission protrusion 502 is provided with a damping layer. The transmission protrusion 502 is connected to the transmission groove 407. The top of the inner wall of the cover housing 501 is provided with a through docking groove 505. The bottom outer arc surface of the cover housing 501 is connected with a docking ring 503. The docking ring 503 is provided with a connecting groove 504.

[0026] The specific working principle is as follows: This device can wrap the torsion spring 302 with the shell, thereby ensuring the stability of the elastic rotation of the torsion spring 302 during actual use. Using this device avoids the need for manual twisting of the torsion spring 302, thereby ensuring accurate installation of the device. When this device is in use, the structure of the support groove 201 can limit the bottom shell 301. At this time, by rotating the two threaded rods 206, the sliding member 205 can be driven to slide, thereby making the arc-shaped limiting member 208 close to the outer arc surface of the bottom shell 301. Thus, the device can clamp and fix the bottom shell 301 through the symmetrical clamping structure.

[0027] After the bottom housing 301 is clamped and fixed, the torsion spring 302 is installed inside the bottom housing 301. One end of the torsion spring 302 passes through the through hole of the bottom housing 301 and the limiting through groove 202 of the base 1, thereby fixing one end of the torsion spring 302.

[0028] After the torsion spring 302 is fixed at the bottom, the cover housing 501 is installed inside the transmission housing 406. At this time, the transmission protrusion 502 is aligned with the transmission groove 407, and the damping layer on the outer side of the transmission protrusion 502 prevents the cover housing 501 from accidentally falling off when installed inside the transmission housing 406. The combination of the transmission protrusion 502 and the transmission groove 407 enables the cover housing 501 to rotate via the transmission housing 406. At this time, the electric lifting telescopic rod 401 drives the lifting plate 402 to descend, causing one top end of the torsion spring 302 to contact the inside of the connecting through groove 505, thereby limiting the top of the torsion spring 302. At this time, rotating the electric telescopic rod 403 drives the rotating rod 405 to rotate, thereby achieving the effect of horizontal rotation of the cover housing 501. The rotation of the cover housing 501 can drive the torsion spring 302 to rotate. When the cover housing 501 rotates to the point where the docking slot 504 and the arc-shaped slot 304 are vertically docked, the limiting post 305 passes through the interior of both the docking slot 504 and the arc-shaped slot 304. Then, the threaded knob 306 is connected to the top of the limiting post 305 and the top thread, so that the threaded knob 306 slides into contact with the side of the connecting ring 303 and the docking ring 503, thereby achieving the effect of the cover housing 501 and the bottom housing 301 being combined and docked and rotating relatively elastically.

[0029] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
