[0028] The wire stripping assembly 1 includes a rotating column 101, the surface of which is rotatably connected to an upper clamp body 102 and a lower clamp body 103 through bearings, and arc grooves 104 are formed on the surface of the upper clamp body 102 and the surface of the lower clamp body 103, and return springs 105 are provided inside the two arc grooves 104;

[0029] The top of the upper caliper body 102 and the bottom of the lower caliper body 103 are both provided with grooves 106 connected to the arc groove 104, and the inner wall of the bottom end of one groove 106 and the inner wall of the top end of the other groove 106 are fixed with a cross plate 108 by screws 107, and one side of the two cross plates 108 is fixed with an arc slider 109 that slides with the arc groove 104, and the top of the two arc sliders 109 is slidably connected to the bottom end of one of the cover plates 204, and the bottom of the two arc sliders 109 is slidably connected to the top of the other cover plate 204, and the reset spring 105 is fixedly arranged between the two arc sliders 109. The screws 107 are removed, and the cross plate 108 is slid out along the groove 106, and the arc slider 109 and the reset spring 105 can be removed, so as to facilitate the inspection and replacement of the reset spring 105;

[0030] The bottom end of the upper clamp body 102 is fixedly provided with an arc frame 110, and the arc frame 110 and the upper clamp body 102 are set as an integrated structure. The bottom end of the arc frame 110 is slidably connected with the top end of the lower clamp body 103, and the front of the upper clamp body 102 and the front of the lower clamp body 103 are fixedly provided with a pressing handle 111, and the surface of the two pressing handles 111 is fixedly provided with an anti-slip sleeve 112, and the contact parts of the upper clamp body 102 and two of the guide boxes 301 are fixedly connected, and the contact parts of the lower clamp body 103 and the other two guide boxes 301 are fixedly connected. The arc frame 110 is sleeved on the outside of the reset spring 105 to cover the gap between the upper clamp body 102 and the lower clamp body 103, so as to protect the reset spring 105. By holding the two pressing handles 111 tightly, the upper clamp body 102 and the lower clamp body 103 are prompted to clamp the optical fiber head, and then the pressing handle 111 is moved to peel through the jaws of the upper clamp body 102 and the lower clamp body 103;

[0031] Specifically, hold the two pressure handles 111 tightly, and the two pressure handles 111 drive the upper jaw body 102 and the lower jaw body 103 to rotate, and the upper jaw body 102 and the lower jaw body 103 rotate with the rotating column 101 as the center.

By pushing the lifting blocks 206, the cover plates 204 slide in the vertical direction, thereby separating the cover plates 204 and the positioning seat 201.

[0035] Specifically, the cover plate 204 is moved and slides along the inner walls of the two adjacent positioning grooves 202 until the cover plate 204 is supported by the upper clamp body 102 or the lower clamp body 103, and then the cover plate 204 is fixed by the fixing component 3. The cover plate 204 will cover the arc groove 104, thereby protecting the reset spring 105 inside the arc groove 104, avoiding the reset spring 105 from being damaged due to being exposed to the outside of the optical fiber stripping pliers, which is beneficial to extending the service life of the optical fiber stripping pliers.

[0039] One end of the four compression springs 305 is fixedly connected to the inner wall of one side of the four guide boxes 301, respectively. The four compression springs 305 are respectively sleeved on the outside of the four slide tubes 304. The surfaces of the four guide boxes 301 are provided with slide grooves 309 that slide with the surface of the push plate 302.

[0040] Specifically, the cover plate 204 slides along the positioning groove 202, and the cover plate 204 will push the block 303 through the inclined surface 306, causing the block 303 to retract into the interior of the through groove 203, and the block 303 will compress the compression spring 305, and then the cover plate 204 is supported by the upper clamp body 102 or the lower clamp body 103, and the groove 205 is aligned with the block 303, and the compression spring 305 will stretch and push the block 303 to be stuck in the interior of the groove 205, completing the fixation of the cover plate 204, without using bolts, and it is convenient to fix the cover plate 204, push the push plate 302, and the push plate 302 drives the block 303 to disengage from the groove 205, so that the fixation can be released, which is convenient for the inspection and maintenance of the reset spring 105.

[0041] When in use, the cover plate 204 slides along the positioning groove 202, and the cover plate 204 pushes the block 303 through the inclined surface 306, causing the block 303 to retract into the interior of the through groove 203, and the block 303 compresses the clamping spring 305, and then the cover plate 204 is resisted by the upper clamp body 102 or the lower clamp body 103, and the clamping groove 205 is aligned with the block 303, and the clamping spring 305 stretches and pushes the block 303 to be clamped into the interior of the clamping groove 205, completing the fixing of the cover plate 204, without using bolts, and facilitating the fixing of the cover plate 204, and the cover plate 204 covers the arc groove 104, thereby protecting the reset spring 105 inside the arc groove 104, and preventing the reset spring 105 from being damaged due to being exposed to the outside of the optical fiber stripping pliers, which is beneficial to prolonging the service life of the optical fiber stripping pliers;

[0042] When it is necessary to strip the optical fiber, the two pressing handles 111 are held tightly, and the two pressing handles 111 drive the upper clamp body 102 and the lower clamp body 103 to rotate, and the upper clamp body 102 and the lower clamp body 103 rotate with the rotating column 101 as the center of the circle, and at the same time, the upper clamp body 102 and the lower clamp body 103 drive the corresponding arc-shaped sliders 109 to slide along the arc groove 104, and the distance between the two arc-shaped sliders 109 is shortened and the reset spring 105 is compressed, and the jaws of the upper clamp body 102 and the lower clamp body 103 will clamp the optical fiber head, and then the pressing handle 111 is moved to strip the fiber;

[0043] When the reset spring 105 needs to be replaced, first push the push plate 302, which drives the card block 303 to disengage from the card slot 205, thereby releasing the fixation of the cover plate 204. Then push the auxiliary lifting block 206, which drives the cover plate 204 to move, causing the cover plate 204 to separate from the positioning seat 201. After that, remove the two screws 107, remove the cross plate 108 and the reset spring 105, and then fix the cross plate 108 at both ends of the new reset spring 105 with two screws 107 to complete the replacement of the reset spring 105, which is very convenient.
