The limiting groove 4 is opened on the outside of the guide sleeve 6. The limiting block 5 is fixedly installed on the inner wall of the control sleeve 3, and the limiting groove 4 is adapted to the limiting block 5. The guide sleeve 6 is disposed on the inner side of the spacer sleeve 2. The guide ball 7 is fixedly disposed on the outside of the guide sleeve 6 and slides in the guide groove 8. The guide groove 8 is spirally opened on the inner wall of the spacer sleeve 2. The sliding plate 10 is fixedly connected to one side of the slider 9 and slides in the sliding groove 11. In the middle, the slide groove 11 is inclinedly opened in the spacer sleeve 2. A protective mechanism is provided on the outside of the spacer sleeve 2. The protective mechanism includes a reset hole 12, a reset groove 13, a reset plate 14, a linkage spring 15, a linkage rod 16, a linkage groove 17, a linkage sleeve 18, a fixing rod 19, and a reset rod 20. The reset hole 12 is opened at one end of the reset groove 13. The reset groove 13 is opened on the reset plate 14. The reset plate 14 is rotatably sleeved on the outside of the spacer sleeve 2. One end of the linkage rod 16 is connected to the outer wall of the control sleeve 3 through the linkage spring 15. The other end of the linkage rod 16 is inserted into the linkage groove 17. Multiple linkage grooves 17 are opened on the outside of the spacer sleeve 2. The reset rod 20 is connected to one side of the linkage sleeve 18 through the fixing rod 19. The linkage sleeve 18 is slidably sleeved on the outside of the spacer sleeve 2. One end of the spacer frame 1 is connected to an adjustment device.

[0032] The adjustment device includes a control sleeve 21, an adjustment rod 22 and an adjustment sleeve 23. The two adjustment rods 22 are respectively connected to the two sides of the adjustment sleeve 23 by threads, and the control sleeve 21 is fixedly installed on the outside of the adjustment sleeve 23.

[0033] One end of the adjusting rod 22 is connected to a grip sleeve 24.

[0034] A damper 25 is connected to the other end of the grip sleeve 24, and the other end of the damper 25 is connected to the spacer sleeve 2. A spring 26 is movably sleeved on the outside of the damper 25.

[0035] An adjusting sleeve 27 is movably provided on the outer side of the damper 25. The inner wall of the adjusting sleeve 27 is connected to the outer wall of the damper 25 by threads. One end of the spring 26 is in abutting relationship with the adjusting sleeve 27.

[0036] In this embodiment, when the interval length needs to be adjusted, first, hold the control sleeve 21 on the outside of the adjustment sleeve 23 with one hand, and then hold the grip sleeve 24 on one end of the corresponding adjustment rod 22 with the other hand. Then, rotate the grip sleeve 24 in the forward direction, so that the grip sleeve 24 drives the adjustment rod 22 to rotate, and drives the spacer frame 1 and other components on one side to rotate. Since the adjustment rod 22 and the adjustment sleeve 23 are connected by threads, the adjustment rod 22 will drive the spacer frame 1 and the spacer sleeve 2 to extend, thereby achieving the purpose of lengthening the interval length. The extension length of the adjustment rod 22 on the other end can also be adjusted according to actual usage needs. When it is necessary to shorten the distance between the two spacer sleeves 2, simply rotate the grip sleeve 24 in the reverse direction. The adjustment sleeves 27 on both sides can also be rotated according to the environment and cable characteristics, so that the adjustment sleeves 27 move along the threads on the outer wall of the damper 25. Then, the adjustment sleeves 27 will squeeze the spring 26 or move to the other side, so that the spring 26 slightly resets, thereby achieving the purpose of adjusting the reset speed and triggering force of the damper 25 after vibration.

[0037] Please see Figures 3-5 As a further implementation of the overall equipment: an adapter plate 28 is fixedly provided inside the spacer sleeve 2, an adapter spring 29 is connected to one side of the adapter plate 28, and the other end of the adapter spring 29 is connected to the slider 9.

[0038] A rubber strip 30 is fixedly provided on one side of the slider 9.

[0039] A reset spring 31 is movably sleeved on the outside of the fixed rod 19 and the reset rod 20. One end of the reset spring 31 is connected to the linkage sleeve 18, and the other end of the reset spring 31 is in contact with the reset plate 14.

[0040] More specifically, when a stable clamping of the cable is required, first adjust the spacing length according to actual needs, then rotate the reset plate 14 clockwise, causing the reset plate 14 to drive the reset groove 13 and reset hole 12 to rotate. When the reset hole 12 rotates to a position concentric with the reset rod 20, push the linkage sleeve 18, causing the linkage sleeve 18 to drive the reset rod 20 to gradually slide into the reset hole 12 through the fixing rod 19. The linkage sleeve 18 will cooperate with the reset plate 14 to compress the reset spring 31. When the reset spring 31 is compressed to its limit, the reset rod 20 just completely passes through the reset hole 12 and moves to the other side of the reset plate 14. Then rotate the reset plate 14 counterclockwise, causing the reset plate 14 to drive the reset hole 12 and reset groove 13 to rotate in the opposite direction. Then the fixing rod 19 enters the reset... In groove 13, the reset rod 20 and the fixing rod 19 cooperate to restrict the linkage sleeve 18 to one side of the reset plate 14, so that the linkage sleeve 18 no longer limits the linkage rod 16. Then, the control sleeve 3 rotates forward, and the control sleeve 3 drives the multiple linkage rods 16 sliding on the side wall to move. Then, the inner wall of the linkage groove 17 presses one end of the linkage rod 16. Due to the rounded corner design at the end of the linkage rod 16 and the edge of the linkage groove 17, one end of the linkage rod 16 slides out of the linkage groove 17, and the other end of the linkage rod 16 will drive the linkage spring 15 to stretch. At the same time, the control sleeve 3 will drive the limiting block 5 set on the inner wall to move. Then, the limiting block 5 will drive the guide sleeve 6 to rotate forward through the limiting groove 4. Then, the guide sleeve 6 will drive the guide ball 7 set on the outer side to slide along the guide groove 8. Due to the screw of the guide groove 8 The rotary structure design allows the guide sleeve 6 to slide along the guide ball 7, and the guide sleeve 6 drives the limiting groove 4 to slide along the limiting block 5. Then, the guide sleeve 6 releases the slider 9, and the adapter spring 29 connected to one side of the adapter plate 28 slowly resets, causing the adapter spring 29 to push the slider 9 to slide. The slider 9 then drives the slide plate 10 to slide along the slide groove 11, and the slider 9 also drives the rubber strip 30 set on one side to move. Due to the inclined structure design of the slide plate 10 and the slide groove 11, the slide plate 10 will drive the slider 9 to move outward while sliding along the slide groove 11. Then, the two cables pass through the spacer sleeve 2 respectively, and then the control sleeve 3 is rotated in the opposite direction, causing the control sleeve 3 to drive the linkage rod 16 and the linkage spring 15 to move again. The control sleeve 3 passes through the limiting block 5 and the limiting... The engagement of groove 4 causes guide sleeve 6 to reverse, then guide sleeve 6 causes outer guide ball 7 to move in the opposite direction, then guide ball 7 slides in the opposite direction along guide groove 8, then guide sleeve 6 causes limiting groove 4 and guide ball 7 to slide in the opposite direction along limiting block 5, then guide sleeve 6 pushes slider 9 to slide, then slider 9 causes slide plate 10 to slide along slide groove 11, then slide plate 10 causes slider 9 to converge inward to achieve sliding reset, then the rubber strip 30 set on the inner side of slider 9 first contacts the outer wall of the cable, then the control sleeve 3 continues to rotate, so that slider 9 fixes and clamps the cable through rubber strip 30, then the rotation of control sleeve 3 stops, then linkage spring 15 drives linkage rod 16 to slide into the corresponding linkage groove 17, then the reset plate 14 is rotated forward again.The reset plate 14 then moves the reset hole 12 and reset groove 13 again. When the reset hole 12 moves to a position concentric with the reset rod 20 and the fixed rod 19, the reset spring 31 pushes the linkage sleeve 18 to slide and reset. Then, the linkage sleeve 18 drives the fixed rod 19 and the reset rod 20 to slide and reset. After the reset spring 31 is fully reset, the reset plate 14 continues to rotate, causing the reset plate 14 to rotate the reset hole 12 and the reset groove 13 to a position that does not correspond to the reset rod 20 and the fixed rod 19. At this time, the fixed rod 19 and the reset rod 20, together with the reset plate 14, support the linkage sleeve 18. With the preload applied by the reset spring 31, the linkage sleeve 18 cannot easily slide. Then, the inner wall of the linkage sleeve 18 limits the outer end of the linkage rod 16. Then, the linkage rod 16 and the linkage groove 17 work together to lock the control sleeve 3, preventing the control sleeve 3 from moving. This ensures the structural stability after cable clamping and ensures stable use of the equipment.

[0041] In summary, when using or operating the overall equipment: First, hold the control sleeve 21 on the outside of the adjusting sleeve 23 with one hand, and then hold the grip sleeve 24 at one end of the corresponding adjusting rod 22 with the other hand. Rotate the grip sleeve 24 clockwise, causing the adjusting rod 22 to rotate, which in turn rotates the spacer 1 and other components on one side. Since the adjusting rod 22 and adjusting sleeve 23 are connected by threads, the adjusting rod 22 will extend the spacer 1 and spacer sleeve 2, thus lengthening the interval. The extension length of the adjusting rod 22 at the other end can also be adjusted according to actual usage needs. When the distance between the two spacer sleeves 2 needs to be shortened, simply rotate the grip sleeve 24 in the opposite direction. Furthermore, depending on the environment and cable characteristics, rotate the adjusting sleeves 27 on both sides, causing them to move along the threads on the outer wall of the damper 25. The adjusting sleeves 27 will then compress the spring 26 or move to the other side, causing the spring 26 to slightly reset, thus adjusting the reset speed and triggering force of the damper 25 after vibration.

[0042] When a stable clamping of the cable is required, first adjust the spacing length according to actual needs. Then, rotate the reset plate 14 clockwise, causing the reset plate 14 to drive the reset groove 13 and reset hole 12 to rotate. When the reset hole 12 rotates to a position concentric with the reset rod 20, push the linkage sleeve 18, causing the linkage sleeve 18 to drive the reset rod 20 to gradually slide into the reset hole 12 through the fixing rod 19. The linkage sleeve 18 will cooperate with the reset plate 14 to compress the reset spring 31. When the reset spring 31 is compressed to its limit, the reset rod 20 just completely passes through the reset hole 12 and moves to the other side of the reset plate 14. Then, rotate the reset plate 14 counterclockwise, causing the reset plate 14 to drive the reset hole 12 and reset groove 13 to rotate in the opposite direction. Then, the fixing rod 19 enters the reset groove 13. Then, the reset rod 20 and the fixing rod 19 cooperate to restrict the linkage sleeve 18 to one side of the reset plate 14, so that the linkage sleeve 18 no longer limits the linkage rod 16. Then, the control sleeve 3 rotates forward, and the control sleeve 3 drives the multiple linkage rods 16 sliding on the side wall to move. Then, the inner wall of the linkage groove 17 presses one end of the linkage rod 16. Due to the rounded corner design at the end of the linkage rod 16 and the edge of the linkage groove 17, one end of the linkage rod 16 slides out of the linkage groove 17, and the other end of the linkage rod 16 will drive the linkage spring 15 to stretch. At the same time, the control sleeve 3 will drive the limiting block 5 set on the inner wall to move. Then, the limiting block 5 will drive the guide sleeve 6 to rotate forward through the limiting groove 4. Then, the guide sleeve 6 will drive the guide ball 7 set on the outer side to slide along the guide groove 8. Due to the spiral structure of the guide groove 8, The design involves a guide sleeve 6 sliding along the guide ball 7, which in turn causes the limiting groove 4 to slide along the limiting block 5. The guide sleeve 6 then releases the slider 9, causing the adapter spring 29 connected to one side of the adapter plate 28 to slowly reset, pushing the slider 9 to slide. The slider 9 then causes the slide plate 10 to slide along the slide groove 11, and the slider 9 also causes the rubber strip 30 on one side to move. Due to the inclined structure of the slide plate 10 and the slide groove 11, the slide plate 10 slides along the slide groove 11 while simultaneously causing the slider 9 to move outwards. The two cables then pass through the spacer sleeve 2. The control sleeve 3 is then rotated in the opposite direction, causing the control sleeve 3 to again move the linkage rod 16 and the linkage spring 15. The control sleeve 3 then passes through the limiting block 5 and the limiting groove 4. The guide sleeve 6 rotates in reverse, causing the outer guide ball 7 to move in the opposite direction. The guide ball 7 then slides in the opposite direction along the guide groove 8. The guide sleeve 6 then causes the limiting groove 4 and the guide ball 7 to slide in the opposite direction along the limiting block 5. The guide sleeve 6 then pushes the slider 9 to slide, which in turn causes the slide plate 10 to slide along the slide groove 11. The slide plate 10 then causes the slider 9 to converge inwards, achieving a sliding reset. The rubber strip 30 on the inner side of the slider 9 first contacts the outer wall of the cable. Then, the control sleeve 3 continues to rotate, causing the slider 9 to clamp the cable securely through the rubber strip 30. The control sleeve 3 then stops rotating, and the linkage spring 15 causes the linkage rod 16 to slide into the corresponding linkage groove 17. Finally, the reset plate 14 rotates forward again.The reset plate 14 then moves the reset hole 12 and reset groove 13 again. When the reset hole 12 moves to a position concentric with the reset rod 20 and the fixed rod 19, the reset spring 31 pushes the linkage sleeve 18 to slide and reset. Then, the linkage sleeve 18 drives the fixed rod 19 and the reset rod 20 to slide and reset. After the reset spring 31 is fully reset, the reset plate 14 continues to rotate, causing the reset plate 14 to rotate the reset hole 12 and the reset groove 13 to a position that does not correspond to the reset rod 20 and the fixed rod 19. At this time, the fixed rod 19 and the reset rod 20, together with the reset plate 14, support the linkage sleeve 18. With the preload applied by the reset spring 31, the linkage sleeve 18 cannot easily slide. Then, the inner wall of the linkage sleeve 18 limits the outer end of the linkage rod 16. Then, the linkage rod 16 and the linkage groove 17 work together to lock the control sleeve 3, preventing the control sleeve 3 from moving. This ensures the structural stability after cable clamping and ensures stable use of the equipment.
