[0022] See also Figure 1-2 The utility model provides a technical solution: a clamping tool for repairing electrical equipment, comprising a block 1 and a counterweight seat 6, with support tubes 61 vertically fixed on both sides of the counterweight seat 6, and a support rod 11 connected to the top of the support tube 61. The bottom of the support rod 11 is inserted into the interior of the support tube 61 in a slidable manner, so that the support rod 11 can adjust the height of the support for the block 1 when it is placed in the support tube 61 and raised and lowered, and a locking bolt 611 is connected to the top of the side of the support tube 61 by a screw connection. When the locking bolt 611 is tightened, its end penetrates into the interior of the support tube 61 and contacts the surface of the support rod 11, thereby locking the support rod 11 and the height of the block 1.

[0023] The block 1 is fixed on the top of the support rod 11 on both sides, and the first clamping block 2 and the second clamping block 3 are respectively provided on both sides of the block 1. The block 1 is parallel to the surface of the counterweight seat 6. The two side surfaces of the side of the first clamping block 2 are installed with a first electric push rod 21 extending through the other side. The end of the extended end of the first electric push rod 21 is fixed to the side surface of the block 1, and the inner surface of the first clamping block 2 and the surface of the block 1 opposite to it are provided with a groove 4, and an air bag 41 is fixed in the groove 4. The air bag 41 and the groove 4 is provided with a rubber sheet, which is pasted between the groove 4 and the air bag 41. The outer side of the air bag 41 leaks out to the outside of the groove 4. Cables of different thicknesses can be placed between the first clamping block 2 and the block 1. The first electric push rod 21 is controlled to be retracted, which can drive the first clamping block 2 to move closer to the block 1. Since the air bag 41 has the ability to be deformed, cables of different thicknesses can be clamped between the first clamping block 2 and the block 1 by the air bag 41, which is convenient for subsequent stripping or terminal connection operations.

[0024] The second electric push rod 31 extending through the other side is installed on both side surfaces of the second clamping block 3. The end of the extended end of the second electric push rod 31 is fixed to the surface of the other side of the block 1. The inner surface of the second clamping block 3 and the surface of the block 1 opposite to it are provided with clamping grooves 5 aligned with each other. There are three groups of clamping grooves 5 of different sizes between the second clamping block 3 and the block 1. When the clamped cable is thick and heavy, the airbag 41 may not be able to lock the cable tightly. At this time, the thick cable can be placed between the second clamping block 3 and the second clamping block 3. , and placed in the appropriate clamping groove 5 between the second clamping block 3 and the resisting block 1 according to its thickness. The second electric push rod 31 is controlled to be retracted, which can drive the second clamping block 3 to move closer to the resisting block 1. The clamping groove 5 is used to cooperate with the rubber pad 51 on its inner surface to clamp and lock the cable, which is also convenient for subsequent stripping or terminal connection operations. A rubber pad 51 is also fixed on the inner surface of the clamping groove 5. The rubber pad 51 is fixed to the inner surface of the clamping groove 5 by fitting. The clamping groove 5 is pressed against the outer surface of the cable through the rubber pad 51 to obtain a more anti-slip clamping and locking effect.

[0025] When in use, the device is supported as a whole by the counterweight seat 6 and placed next to the electrical equipment to be repaired or the distribution cabinet, so that the first electric push rod 21 and the second electric push rod 31 are connected to their controllers and powered on. Before use, the locking bolt 611 located on the side of the support tube 61 can be loosened so that its ends no longer contact the outer surface of the support rod 11. The support rod 11 can slide up and down in the support tube 61 to change the support height of the upper block 1, and then tighten the locking bolt 611 to lock the supported height of the block 1. When repairing electrical equipment, the cables are removed and the cables are operated. When clamping some lighter cables, the cables are placed vertically between the block 1 and the first clamping block 2, and then controlled to make The first electric push rod 21 is retracted, which can drive the first clamping block 2 to approach the block 1. Since the air bag 41 has the ability to be deformed, cables of different thicknesses can be clamped between the first clamping block 2 and the block 1 by the air bag 41, which is convenient for subsequent operations such as stripping or connecting terminals. When the removed cable is a relatively thick and heavy cable, it can be placed in a suitable clamping groove 5 between the second clamping block 3 and the block 1 according to its thickness. The second electric push rod 31 is controlled to be retracted, which can drive the second clamping block 3 to approach the block 1. The clamping groove 5 is used in conjunction with the rubber pad 51 on its inner surface to clamp and lock the cable, which is also convenient for subsequent operations such as stripping or connecting terminals. Even if there is no need to perform processing such as stripping on the cable, the device can be used as a cable locking tool to avoid the cable being placed on the ground and inconvenient to pick up and connect to electrical equipment again.
