[0039] Specifically, both ends of the arc-shaped base plate 201 are provided with buffer arc plates 202, one end of the buffer arc plate 202 is provided with a buffer pad 203, the inside of the arc-shaped base plate 201 is provided with a plurality of reinforcing arc plates 207, the outer wall of the buffer pad 203 is provided with an elastic clamping plate 204, and one end of the elastic clamping plate 204 is provided with a guide arc plate 206.

[0040] Specifically, both ends of the buffer pad 203 are provided with elastic push plates 205. One end of the elastic push plate 205 is connected to one end of the guide arc plate 206. The elastic clamping plate 204 and the elastic push plate 205 are arranged in an alternating manner at one end of the guide arc plate 206.

[0041] Specifically, both ends of the arc-shaped base plate 201 are provided with elastic connecting plates 209, one end of the elastic connecting plate 209 is provided with a fixed base plate 210, one end of the fixed base plate 210 is provided with a clamping pad 211, and the fixed clamping seat 104 is provided with a limiting slot 108.

[0047] Example 1

[0048] In this embodiment, to address the issue of force during rapid cable rebound, the technical solution is as follows (refer to...). Figures 1 to 5 The buffer arc plate 202 is C-shaped and is located on both sides of the arc-shaped base plate 201, exhibiting a mirror-symmetrical structure. The reinforcing arc plate 207 is also C-shaped and is located on the inner wall of the arc-shaped base plate 201, exhibiting a mirror-symmetrical structure. The reinforcing arc plate 207 is positioned between the arc-shaped base plate 201 and the buffer pad 203. When the cable suddenly loosens and rebounds rapidly, the cable comes into contact with the buffer pad 203. Under the action of the buffer arc plate 202 and the reinforcing arc plate 207, the rebound force of the cable is reduced, preventing the rapidly rebounding cable from impacting the fixing device and causing damage to the cable and the fixing device. On the other hand, it can restrict the position of the cable when adjusting the tension, preventing the position of the cable from shifting during tension adjustment and affecting the cable tension adjustment process.

[0049] It should be noted that the guide arc plate 206 is C-shaped and is located on both sides of the buffer pad 203 in a mirror symmetrical structure. The guide arc plate 206 is connected to the buffer pad 203 through the elastic clamp 204. When the cable rebounds rapidly, the guide arc plate 206 guides the cable to make precise contact with the buffer pad 203, which can reduce the rebound force of the cable and prevent the rapidly rebounding cable from impacting the fixing device and causing damage to the cable and the fixing device.

[0050] As a further limitation of this technical solution, the fixing plate 208 has an arc-shaped curved surface structure. The fixing plate 208 is set on both sides of the arc-shaped base plate 201 and has a mirror symmetrical structure. The shape of the fixing plate 208 is adapted to the shape of the fixing slot 109. In use, by installing the fixing plate 208 into the fixing slot 109, it is convenient to install the buffer mechanism 2 onto the adjusting push plate 106, which can reduce the rebound force of the cable.

[0051] Example 2

[0052] In this embodiment, to address the issue of potential positional shifts in the cable during tension adjustment and rebound, the technical solution is as follows (refer to...). Figures 1 to 5 The elastic clamp 204 has an arc-shaped elastic curved surface structure, and the elastic push plate 205 has an arc-shaped curved surface structure. The elastic clamp 204 and the elastic push plate 205 are arranged in a linear staggered array outside the buffer pad 203. One end of the elastic clamp 204 is connected to one end of the guide arc plate 206. When adjusting the tension of the cable, the cable is placed on the outer wall of the buffer pad 203. During the adjustment process, the buffer pad 203 is squeezed and the elastic push plate 205 is pushed, which in turn squeezes the elastic clamp 204 towards the center. With the help of the elastic clamp 204, the position of the cable can be restricted, so as to avoid the position of the cable shifting when adjusting the tension and affecting the cable tension adjustment process. Moreover, when the cable rebounds quickly, under the action of the guide arc plate 206, the cable can accurately contact the buffer pad 203, so as to avoid the position of the cable shifting when rebounding and affecting the cable buffering effect.

[0053] Example 3

[0054] In this embodiment, to solve the problem of the inconvenience of fixing the buffer mechanism 2, the technical solution of this implementation is as follows, for reference. Figures 1 to 5 The positioning plate 213 has an arc-shaped elastic curved surface structure. The positioning plate 213 is set on both sides of the limiting block 212 and has a mirror symmetrical structure. The shape of the positioning plate 213 is adapted to the shape of the positioning slot 107. The positioning plate 213 is set at both ends of the fixed support plate 214 and has a mirror symmetrical structure. The clamping pad 211 is set outside the fixed base plate 210 and between the fixed clamping seats 104. The shape of the limiting block 212 is adapted to the shape of the limiting slot 108. When clamping the cable, the clamping pad 211 further clamps the cable and squeezes the fixed support plate 214. When the fixed support plate 214 deforms, it pushes the positioning plate 213, so that the positioning plate 213 is fixed inside the positioning slot 107, which can ensure the firmness of the fixed base plate 210 in the fixed clamping seat 104.

[0055] Based on the above embodiments, it can be concluded that during use, by installing the limiting block 212 into the limiting slot 108, and then fixing the positioning plate 213 into the positioning slot 107, while fixing the plate 208 into the fixing slot 109, and installing the buffer mechanism 2 onto the outside of the adjusting push plate 106, when the tension of the cable is adjusted and the cable rebounds rapidly, the cable comes into contact with the buffer pad 203. Under the action of the buffer arc plate 202 and the reinforcing arc plate 207, the rebound force of the cable is reduced, thus preventing the rapidly rebounding cable from impacting the fixing device and causing damage to the cable and the fixing device.
