[0028] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0029] Reference Figure 1-Figure 6 As shown, a wire clamp includes a main board 1, a lower jaw 2 is arranged at the bottom of the main board 1, a pull rod 3 is inserted on the main board 1, one end of the pull rod 3 is rotatably connected to a connecting plate 4 through a first rotating shaft, one side of the connecting plate 4 is rotatably connected to the main board 1 through a second rotating shaft, and the side of the connecting plate 4 away from the second rotating shaft is rotatably connected to an upper jaw 5 through a third rotating shaft, wherein a screw groove is provided at a position where the upper jaw 5 is opposite to the lower jaw 2, mainly for increasing friction and fixing and clamping the line; and further includes:

[0030] A recycling component, installed on the main board 1, used for recycling the cable holder;

[0031] The wire take-up device 7 is detachably mounted on the support plate 70. When in use, the wire take-up device 7 can be removed from the support plate 70, and the staff always holds the wire take-up device 7;

[0032] A self-locking component 8 is installed on a side of the main board 1 away from the connecting plate 4, and the self-locking component 8 is connected to the second rotating shaft, and is used to lock the upper jaw 5 and the lower jaw 2;

[0033] After the line is clamped, the pull rod 3 is pulled to keep the upper jaw 5 and the lower jaw 2 close to each other. When the upper jaw 5 and the lower jaw 2 are released, the self-locking component 8 locks the upper jaw 5 and the lower jaw 2 to prevent them from falling off.

[0034] The driving assembly 9 is mounted on the top plate 6, the first cable 71 passes through the bottom of the driving assembly 9, and one side of the driving assembly 9 is connected to the self-locking assembly 8 through the second cable 80;

[0035] It is mainly used to allow the driving component 9 to open the self-locking component 8 through the second cable 80 when retrieving the wire clamp, and then the upper jaw 5 and the lower jaw 2 can be moved away from each other to release the line;

[0036] In one embodiment, the recovery assembly includes a top plate 6 mounted on the top of the main plate 1;

[0037] A wire take-up device 7, both ends of which are mounted on the top plate 6 via a support plate 70, a first cable 71 is wound inside the wire take-up device 7, and one end of the first cable 71 away from the wire take-up device 7 is connected to a first rotating shaft;

[0038] The wire take-up device 7 may adopt a tape measure structure design, and a clockwork spring may be provided inside, and the first cable 71 is wound around the clockwork spring, so that when it is recovered, the first cable 71 can be automatically recovered and wound into the wire take-up device 7.

[0039] In one embodiment, a mounting frame 72 is sleeved on the first rotating shaft, a connecting block 73 is arranged on the mounting frame 72, a first guide roller 74 and a second guide roller 75 are arranged on the top plate 6 in sequence, and the first cable 71 passes through the driving assembly 9, the first guide roller 74, the second guide roller 75 in sequence and is connected to the connecting block 73;

[0040] When retrieving the wire gripper, it is necessary to separate the upper jaw 5 from the lower jaw 2. This can be done by pulling the first cable 71. The first cable 71 pulls the second shaft upward through the mounting bracket 72, thereby driving the connecting plate 4 to deflect along the first shaft, thereby driving the upper jaw 5 to move upward.

[0041] In one embodiment, a hook 76 is provided on the side of the cable take-up device 7 away from the first cable 71. After the staff takes it down, it can be hung around the waist or other places. Fixed shafts 77 are also provided at both ends of the cable take-up device 7. A telescopic button 78 is slidably provided on the fixed shaft 77. The fixed shaft 77 is inserted into the support plate 70 through the telescopic button 78. The telescopic button 78 itself has a certain elasticity. When taking it down, the telescopic button 78 can be pressed inward to shrink it inward and detach it from the support plate 70, so that it can be directly taken down.

[0042] In one embodiment, the self-locking assembly 8 includes a ratchet 81 connected to the second rotating shaft, a ratchet bar 82 rotatably connected to the main board 1 is disposed on one side of the ratchet 81, a first baffle 83 is disposed on one side of the ratchet bar 82, a second baffle 84 is disposed on the other side of the ratchet bar 82, a return spring 85 is disposed between the ratchet bar 82 and the second baffle 84, an L-shaped plate 821 is welded on the side of the ratchet bar 82 away from the ratchet 81, and an end of the second cable 80 away from the driving assembly 9 is connected to the L-shaped plate 821;

[0043] By setting the ratchet 81 and the ratchet bar 82, the connecting plate 4 can only deflect downward along the second rotating shaft, that is, the upper jaw 5 can only move downward to prevent accidental loosening and cause the line to fall off. When the wire clamp needs to be opened, it is necessary to first stir the ratchet bar 82 to make the ratchet bar 82 disengage from the ratchet wheel 81. In this way, the second rotating shaft can be reversed to allow the upper jaw 5 to move away from the lower jaw 2.

[0044] In one embodiment, a ring 86 is sleeved on the L-shaped plate 821, and a first pull ring 87 is hinged on the ring 86. A second pull ring 88 engaged with the first pull ring 87 is provided at one end of the second cable 80 away from the driving assembly 9. When the first cable 71 is pulled, the first cable 71 will first drive the second cable 80 to move upward through the driving assembly 9, and the second cable 80 will pull the L-shaped plate 821, so that the ratchet 82 rotates, disengages from the ratchet 81, and opens the self-locking assembly 8.

[0045] In one embodiment, the driving assembly 9 includes two first vertical plates 91 installed on the top plate 6, a first lifting plate 93 is arranged between the two first vertical plates 91, a pressure roller 94 is arranged at the bottom of the first vertical plate 91, the first cable 71 passes through the bottom of the pressure roller 94, a compression spring 95 is arranged in the first vertical plate 91, the first lifting plate 93 is slidably connected to the first vertical plate 91 through the compression spring 95, and a driven assembly for pulling the second cable 80 is arranged on the top of the first lifting plate 93;

[0046] When the first cable 71 is pulled, the first cable 71 is tightened to push the first lifting plate 93 upward, and the first lifting plate 93 moves upward to push the driven component, so that the driven component pulls the second cable 80 to move.

[0047] In one embodiment, the driven assembly includes a second vertical plate 92 fixed on the first vertical plate 91, a second lifting plate 98 is slidably connected between the two second vertical plates 92, a protrusion 99 is provided at one end of the second lifting plate 98, an end of the second cable 80 away from the self-locking assembly 8 is sleeved on the protrusion 99, a bracket 96 is provided on the first lifting plate 93, a top block 97 for driving the second lifting plate 98 to move up and down is welded on the bracket 96, and there is a certain gap between the top block 97 and the second lifting plate 98 at the beginning;

[0048] When the first lifting plate 93 moves upward, the top block 97 can push the second lifting plate 98 to move upward. The second lifting plate 98 moves upward and pulls the second cable 80 through the protrusion 99, so that the ratchet bar 82 moves away from the ratchet wheel 81. At this time, the restraint of the second rotating shaft disappears, and the first cable 71 continues to be pulled. The first cable 71 will pull the mounting frame 72, thereby driving the connecting plate 4 to deflect upward, so that the upper jaw 5 moves away from the lower jaw 2.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
