AI Technical Summary
As the operating time of existing heating pipe networks increases, the resistance to opening or closing control valves increases, and ordinary wrenches cannot provide the necessary adjustment assistance, making high-altitude operations inconvenient and increasing the risk.
A power-assisted wrench for thermal maintenance has been designed, including a slot, a built-in guide rail, and a slide plate. The length of the power-assisted rod and the movement of the slide plate can be adjusted by adjusting the bolts to achieve convenient operation of the valve.
This technology enables convenient valve operation under varying resistance levels, reduces the risks of working at heights, and improves the ease of use and operational efficiency of the tools.

[0006] In particular, the utility model provides a heat power overhaul power wrench, which comprises a clamping groove, a fixed hole penetrating the middle part of the clamping groove, an inner guide rail and an inner sliding plate arranged in the fixed hole, and the inner guide rail and the inner sliding plate are slidingly connected.
[0007] A power lever is symmetrically arranged around the clamping groove.
[0008] An adjusting bolt is arranged on one side of the clamping groove, and the adjusting bolt is movably connected with the inner sliding plate through the clamping groove.
[0009] Further, the inner sliding plate comprises a notch, and the inner sliding plate is mounted on the inner guide rail through the notch.
[0010] Further, the power lever comprises an inner rod and an outer rod, one end of the inner rod is fixedly connected with the clamping groove, the other end of the inner rod is sleeved with one end of the outer rod, and the inner diameter of the outer rod is greater than the outer diameter of the inner rod.
[0011] Further, the inner sliding plate is provided with a perforation corresponding to the insertion end of the adjusting bolt.
[0012] Further, the inner guide rail is in a strip shape, and a preset distance is arranged between the inner guide rail and the upper opening of the clamping groove.
[0013] The technical effects and advantages of the utility model are as follows:
[0014] The utility model discloses a flexible force arm length can be adjusted, and the valve of different resistance is opened, and the utility model discloses a valve rotating part is first aligned with the need adjusting in use, then the outer rod is pulled out from the inner rod, and the extension is carried out to make the force arm lengthen, and the adjusting bolt is rotated simultaneously, and the adjusting bolt is rotated to push the built -in slide to move to make the built -in slide clamping fixed different valve rotation, and the utility model discloses convenient and fast, and the power is adjusted conveniently.
