[0013] Furthermore, a reflective sheet is included, and each air pump is fixedly connected with the reflective sheet.

[0014] Furthermore, a method for using an auxiliary insulating tool for cable repair is provided, and the specific steps are as follows: Step 1: first, move the merging block to the lower side of the cable, and then start the micro motor connected to the merging block through the control button, and then drive the two merging blocks to rotate toward opposite sides and merge through the micro motor, and then use the air pump to pump nitrogen in the storage into the air bag, so that the air bag expands to clamp and fix the cable located in the middle of the two merging blocks;

[0015] Step 2: After the cable is clamped and fixed, the worker shakes the first rotating handle up and down to drive the second wedge block to swing up and down, thereby driving the first connecting rod, the first linkage rod and the extension rod to move downward, thereby driving the wire cutters to rotate to the opposite side to cut the cable;

[0017] The beneficial effects are as follows: the cable is limited in position within the two merging blocks by the merging block, and then the gas in the storage is extracted into the air bag by the air pump, and then the cable is clamped and fixed by the expansion of the air bag. At this time, the cable is clamped in the middle of the two merging blocks, just in the wire cutters, which is convenient for workers to align the wire cutters with the cable; it is easy to use and does not require the assistance of others, which greatly improves work efficiency; and the gas in the storage is nitrogen. When the cable is cut and there is flashing discharge, the worker can quickly open the electric valve through the control button to release the nitrogen in the air bag to extinguish the arc, thereby avoiding damage to the tool and avoiding more dangerous accidents;

[0018] When the sliding ring moves downward to cut the cable, the sliding ring drives the second linkage rod to move downward and generate adaptive rotation, thereby driving the left fixed frame to move downward. At this time, the left fixed frame rotates counterclockwise around the rotation point of the fixed block, thereby pulling the clamped cable, straightening the bent cable, and pulling it into the wire cutter, thereby tightening and correcting the cable in the wire cutter during the cutting process, so as to facilitate the cutting of the cable;

[0019] When encountering a situation where cables are hanging and space is limited, workers can rotate the fixing frame and merging block on the right side to the back of the wire cutters by rotating the assembly; and then perform the cutting operation, which makes it easier for workers to perform wire cutting operations in limited space, greatly improving the practicality of the equipment.

[0038] The airbag 105 is made of nitrile rubber and has good insulation and wear resistance.

[0039] An anti-slip cover 1001 is provided on the handheld device at the lower side of the insulating rod 1, and the anti-slip cover 1001 is made of sponge material.

[0040] It also includes a fixing block 101 and a second linkage rod 110 ; the fixing block 101 is fixedly connected to the upper side of the insulating rod 1 , and the fixing block 101 is rotatably connected to the fixing frame 103 on the left; the second linkage rod 110 is rotatably connected between the fixing frame 103 on the left and the sliding ring 3 .

[0041] The working principle of the above embodiment is as follows:

[0042] First, Figure 1 The first connecting rod 5 is the front side. Before cutting the wire, the worker will cut off the power supply. Figure 2 As shown, at this time, the wire cutter 2 is in an open state, and the merging block 104 is also in an open state; first, the worker holds the insulating rod 1 and lifts the insulating rod 1 upward to make the wire cutter 2 close to the cable 555 to be cut; in this process, the worker does not need to align the wire cutter 2 with the cable 555, but only needs to move the opened merging block 104 to the lower side of the cable 555, and then the worker starts the micro motor connected to the merging block 104 through the control button, and then drives the two merging blocks 104 to rotate and merge to the opposite sides through the micro motor, and then as shown in Figure 3 and Figure 4 As shown: at this time, the cable 555 is located in the middle of the two merged blocks 104; then the worker starts the air pump 107 through the control button, and then the air pump 107 draws external air into the air bag 105, and then the air bag 105 expands to clamp and fix the cable 555 located in the middle of the two merged blocks 104, and at this time, the cable 555 is clamped in the middle of the two merged blocks 104, just located in the wire cutter 2, and the operation is simple; then as shown Figure 2-Figure 6As shown: the worker shakes the first rotating handle 6 up and down to drive the second wedge block 203 to swing up and down. When the second wedge block 203 moves upward, the first connecting rod 5 is stuck by the second limiting block 204 and cannot move upward. At this time, the second wedge block 203 is contacted and squeezed by the wedge groove 5002, and the second spring 20301 is compressed and contracted. The second wedge block 203 moves forward and then crosses the corresponding wedge groove 5002. When the second wedge block 203 moves downward, the second wedge block 203 is stuck in the wedge groove. The first connecting rod 5 moves downwards, and the second limit block 204 is squeezed and moves forwards. The third spring 20401 is compressed and contracts, and the wedge-shaped groove 5002 passes over the second limit block 204, and the first connecting rod 5 moves downwards smoothly; and then the sliding ring 3 and the first linkage rod 2002 move downwards. At this time, the first linkage rod 2002 rotates adaptively and drives the extension rod 2001 to move downwards, and then drives the wire cutter 2 to rotate to the opposite side through the extension rod 2001 to tighten the cable 5. 55 for shearing; after the shearing is completed, the worker only needs to rotate the rotating rod 5001 to rotate the wedge-shaped groove 5002 to the right, so that the second wedge block 203 is disengaged from the wedge groove 5002, and the second wedge block 203 and the second limit block 204 are squeezed by the first connecting rod 5, so that the second wedge block 203 and the second limit block 204 move forward, and then push the first connecting rod 5 upward. At this time, the second wedge block 203 and the second limit block 204 will not hinder the upward movement of the first connecting rod 5, and the second wedge block 203 and the second limit block 204 will not hinder the upward movement of the first connecting rod 5. The sliding ring 3, the extension rod 2001, the first linkage rod 2002 and the wire cutters 2 are smoothly moved and reset; then the worker controls the air pump 107 through the control button to release part of the gas in the airbag 105, thereby releasing the clamping of the airbag 105 on the cable 555, and then removes the insulating rod 1, and then the worker pulls out the first limit block 108, and rotates the merged merging block 104 to the opposite side to reset it for subsequent use; it is easy to use, does not require the assistance of others, and greatly improves work efficiency.

[0043] Furthermore, during the inflation of the airbag 105, the airbag 105 will squeeze the merging block 104, causing the merging block 104 to rotate and open to the opposite sides, causing the cable 555 to fall off. Therefore, when the two merging blocks 104 on the fixing frame 103 are merged, the first wedge block 109 enters the corresponding second fixing groove 10401. During this process, the first wedge block 109 will squeeze the first limit block 108 upward. At this time, the first spring 10801 is compressed and contracts, and the first limit block 108 moves upward over the front end of the first wedge block 109 and enters the limit groove 10901, and then the first wedge block 109 is clamped into the second fixing groove 10401 through the first limit block 108, thereby fixing the two merged merging blocks 104 to prevent the airbag 105 from squeezing the merging blocks 104 to open to the opposite sides after inflation, causing the cable 555 to be squeezed out, affecting the clamping effect of the airbag 105 on the cable 555.

[0044] Furthermore, when encountering a loose cable 555, after the cable 555 is clamped by the merging block 104 and the airbag 105, the cable 555 in the wire cutter 2 is not in a taut state, which affects the cutting of the cable 555 by the wire cutter 2. If the cable 555 in the wire cutter 2 is not in a taut state, the cable 555 may not be completely inserted into the wire cutter 2. Therefore, in the process of rotating the first rotating handle 6 to drive the sliding ring 3 to move downward, the second linkage rod 110 moves downward and generates an adaptive rotation, and drives the left fixing frame 103 to move downward. At this time, Figure 2 As shown: based on the view from the front to the back, the left fixing frame 103 will rotate counterclockwise around the rotation point of the fixing block 101, thereby pulling the clamped cable 555, straightening the bent cable 555, and pulling it into the wire cutter 2, thereby tightening and correcting the cable 555 in the wire cutter 2 during the cutting process, so as to facilitate cutting of the cable 555.

[0045] Furthermore, after the cable 555 is cut, one end of the cable 555 is fixed on the eaves or the pole, and the other end hangs down on the ground. At this time, the worker needs to cut off the excess cable 555 hanging on the ground; at this time, the fixed end of the cable 555 on the eaves or the pole hangs down, and the space available for clamping is limited; therefore, Figure 6 and Figure 7As shown in the figure: in the initial state, the second rotating handle 202 is located in the first fixed groove 4002 at the front end of the slide groove 4001. At this time, the second connecting rod 201 and the second rotating handle 202 are limited by the first fixed groove 4002 and cannot move, so the rotating block 102 and the fixing frame 103 on the right side cannot move; when the cable 555 is hanging down and the space is limited, the worker can turn the second rotating handle 202 upward into the slide groove 4001, and then, based on the view from top to bottom, the worker drives the second connecting rod 201 in the slide groove 4001 through the second rotating handle 202. 001 rotates counterclockwise, thereby driving the rotating block 102 and the fixing frame 103 on the right to rotate counterclockwise, and rotating the fixing frame 103 on the right and the merging block 104 to the rear of the wire cutter 2, and then the worker rotates the second rotating handle 202 to the first fixing groove 4002 on the rear side to fix the second connecting rod 201 and the second rotating handle 202; then the worker moves the merging block 104 on the left to the lower side of the cable 555, and then performs the cutting operation, which is convenient for the workers to perform wire cutting operations under limited space, greatly improving the practicability of the equipment.

[0046] On the basis of the above technical effects, the present invention also has the following advantages:

[0047] The airbag 105 is made of nitrile rubber and has good insulation and wear resistance;

[0048] An anti-slip cover 1001 is provided on the lower side of the insulating rod 1. The anti-slip cover 1001 is made of sponge material, which is convenient for workers to hold the insulating rod 1 for maintenance work.

[0049] Example 2

[0050] On the basis of Example 1, Figure 7 As shown, it also includes a memory 106 and an electric valve 206; each merging block 104 is fixedly connected to two memory cells 106, and each memory cell 106 stores nitrogen; each memory cell 106 is connected to a corresponding air pump 107; each air bag 105 is fixedly connected to four electric valves 206 on one side close to the wire cutters 2, and the electric valves 206 are electrically connected to the control button.

[0051] A reflective sheet 205 is also included, and each air pump 107 is fixedly connected with the reflective sheet 205 .

[0052] A method for using an auxiliary insulating tool for cable 555 repair, the specific steps are as follows:

[0053] Step 1: First, move the merging block 104 to the lower side of the cable 555, and then start the micro motor connected to the merging block 104 through the control button, and then drive the two merging blocks 104 to rotate and merge toward the opposite sides through the micro motor, and then pump the nitrogen in the storage 106 into the air bag 105 through the air pump 107, so that the air bag 105 expands to clamp and fix the cable 555 located in the middle of the two merging blocks 104;

[0054] Step 2: After the cable 555 is clamped and fixed, the worker shakes the first rotating handle 6 up and down to drive the second wedge block 203 to swing up and down, thereby driving the first connecting rod 5, the first linkage rod 2002 and the extension rod 2001 to move downward, thereby driving the wire cutters 2 to rotate to the opposite side to cut the cable 555;

[0055] Step 3: After the cutting is completed, the worker only needs to rotate the rotating rod 5001 to rotate the wedge groove 5002 to the right, thereby disengaging the second wedge block 203 from the wedge groove 5002, and then push the first connecting rod 5 upward, thereby moving the sliding ring 3, the extension rod 2001 and the first linkage rod 2002 upward to reset, thereby driving the wire cutters 2 to rotate to the opposite side to reset; then pull out the first limit block 108, and then rotate the merged merging block 104 to the opposite side to reset for subsequent use.

[0056] When encountering some aging lines or power controller damage, and the power supply is not turned off, the cable 555 will often encounter flash discharge after being cut short, causing damage to the motor of the equipment, resulting in damage to the equipment workpiece, and even causing greater dangerous accidents; therefore, nitrogen is stored in each storage 106. During normal operation, the nitrogen in the storage 106 is pumped into the airbag 105 through the air pump 107, so that the airbag 105 expands to clamp the cable 555. When the cable 555 is cut and flashes, the worker can quickly open the electric valve 206 through the control button to release the nitrogen in the airbag 105 to extinguish the arc, thereby avoiding damage to the tools and greater dangerous accidents; and when performing maintenance work at night, the reflective sheet 205 reflects light to warn passing vehicles and workers, thereby improving the safety of maintenance work.

[0057] Step 3: After the cutting is completed, the worker only needs to rotate the rotating rod 5001 to rotate the wedge groove 5002 to the right, thereby disengaging the second wedge block 203 from the wedge groove 5002, and then push the first connecting rod 5 upward, thereby moving the sliding ring 3, the extension rod 2001 and the first linkage rod 2002 upward to reset, thereby driving the wire cutters 2 to rotate to the opposite side to reset; then pull out the first limit block 108, and then rotate the merged merging block 104 to the opposite side to reset for subsequent use.
