DETAILED DESCRIPTION

[0020] See also Figures 1 to 4The utility model includes an adjustable wrench handle 1, the front end of the movable wrench handle 1 is provided with an adjustable jaw, the end surface of the rear end is provided with a blind hole, an extended handle 7 is slidably installed inside the blind hole, a transverse horizontal liquid pipe 9 and a longitudinal horizontal liquid pipe 8 are installed on the side wall of the extended handle 7, one end of the extended handle 7 is provided with a U-shaped groove, and a wire cutter is installed inside the U-shaped groove, and pin holes connected with the blind hole are provided on the upper and lower sides of the movable wrench handle 1. A positioning pin 6 is movably installed in the pin hole, an outer stopper 603 is provided on the inner wall of the outer end of the pin hole, a pull disk is provided at one end of the positioning pin 6 located outside the pin hole, an inner stopper 602 is installed on the side wall of the positioning pin 6, and a compression spring 601 is provided in the pin hole, the compression spring 601 is sleeved on the positioning pin 6 and is elastically connected with the inner stopper 602 and the outer stopper 603, that is, the two ends of the compression spring 601 are respectively pressed against the inner stopper 602 and the outer stopper 603. A slot 10 matching the positioning pin 6 is provided on the extended handle 7 , and a rubber layer is installed inside the slot 10 .

[0021] When in use, you can hold the pull disk at the end of the positioning pin 6 with your hand, pull the positioning pin 6 outward (compressing the compression spring 601 at the same time), pull the positioning pin 6 out of the slot 10, disconnect the positioning pin 6 from the slot 10, and thus pull the extended handle 7 out of the blind hole at the end of the movable wrench handle 1, so that the total length of the movable wrench handle 1 and the extended handle 7 is increased. When the extended handle 7 is pulled out to a length that meets the use requirements, release the positioning pin 6. Under the action of the elastic restoring force of the compression spring 601, the positioning pin 6 is connected with the slot 10 at other positions outside the extended handle 7, thereby extending the power arm.

[0022] The adjustable jaws at the front end of the movable wrench handle 1 include an adjusting nut 2, a ring 3 and an adjusting rod 5. The ring 3 is fixedly connected to the movable wrench handle 1. A nut mounting groove is provided in the middle of the ring 3. The adjusting nut 2 is rotatably installed in the nut mounting groove. The adjusting rod 5 is parallel to the axis of the movable wrench handle 1 and the extended handle 7. The adjusting rod 5 passes through the ring 3 and the adjusting nut 2 and cooperates with the adjusting nut 2 through threads. The cross-section of the adjusting rod 5 is rectangular and can only move axially in the ring 3 but cannot rotate. A movable jaw 4 is provided at the front end of the adjusting rod 5, and a fixed jaw 101 corresponding to the movable jaw 4 is provided at the front end of the movable wrench handle 1.

[0023] The wire cutters include a first clamp arm 701 and a second clamp arm 702, which are connected to each other by an interlaced rotation shaft, one end of which is fixed to the extended handle 7, and clamp heads 704 are provided at the tops of the first clamp arm 701 and the second clamp arm 702, and a spring 705 is provided between the first clamp arm 701 and the second clamp arm 702. Limiting rotating blocks 703 for limiting the positions of the first clamp arm 701 and the second clamp arm 702 are installed on both side surfaces of the extended handle 7, and one end of the limiting rotating block 703 is rotationally connected to the extended handle 7 by a damping rotating shaft. During the installation of the lightning arrester, it is necessary to cut the wires. The limiting rotating block 703 is rotated to release the limiting of the first clamp arm 701 and the second clamp arm 702, so that the first clamp arm 701 and the second clamp arm 702 are unfolded under the elastic force of the spring 705, and the wires are cut by the clamp heads 704.

[0024] The working principle of the utility model is: when in use, the adjusting nut 2 is rotated to make the adjusting rod 5 slide in the collar 3, so that the distance between the movable jaw 4 and the fixed jaw 101 can be adjusted, so that the device as a whole can be suitable for screws of different sizes. At the same time, when in use, the positioning pin 6 can be pulled to disconnect the clamping connection between the positioning pin 6 and the card slot 10, so that the extended handle 7 can be pulled out from the blind hole at the end of the movable wrench handle 1, which plays the role of extending the power arm and facilitates the reinforcement and removal of the bolts. When it is necessary to observe the horizontality of the lightning arrester installation surface, the positioning pin 6 can be pulled to directly pull the extended handle 7 out from the inside of the movable wrench handle 1, and then the horizontality can be measured through the horizontal liquid pipe 9 or the vertical liquid pipe 8 on the side wall of the extended handle 7. When it is necessary to cut the wires during the installation of the lightning arrester, the limit on the first clamp arm 701 and the second clamp arm 702 is released by rotating the limit switch 703, so that the first clamp arm 701 and the second clamp arm 702 are unfolded, and then the first clamp arm 701 and the second clamp arm 702 are squeezed inward to cut the wires between the two clamp heads 704.

[0025] The utility model has the functions of tightening and loosening bolts, cutting cables and measuring horizontality. Only one tool is needed for installing and disassembling outdoor facilities such as lightning arresters. The utility model is very convenient to carry and operate and is not easy to lose, which well solves the problems existing in the background technology.
