Abstract
The utility model relates to a maintaining tool for the field of power construction, in particular to a fastening tool of a transformer tapping switch. The technical scheme is as follows: the fastening tool comprises a movable wrench and is characterized in that the head part and a handle of the movable wrench are rotatablely connected by a pin. The fastening tool has the effects of: connecting the handle and the head part of the movable wrench by the pin in a segment way, being disassembled for use at any angle, reducing the planar rotating area, avoiding a transformer sleeve, adopting a sliding module and an adjusting screw to adjust the size of the head part of the wrench, being convenient in operation, saving time and labor, arranging an internal hexagonal wrench matched and used with the adjusting screw into the movable wrench, having convenient carry and being not easy to be lost.
Description
Technical field
The utility model relates to the maintenance tool of using in a kind of power equipment construction field, specifically is a kind of sub-connecting switch of transformer fastened tools.
Background technology
Because tapping switch for electric power transformer is in outdoor work environment for a long time, and be subjected to the influence throughout the year of spring, summer, autumn, winter, the shunting switch rubber blanket can produce aging phenomenon, and produce different contractions and distortion, and simultaneously can with ooze, oil leakage phenomenon takes place, instrument commonly used is a monkey wrench when maintenance, but because of sub-connecting switch of transformer is installed in the middle of the bushing shell for transformer, the handle of existing monkey wrench with fixedly connected, be not suitable between bushing shell for transformer, rotating, and regulate the openings of sizes inconvenience of monkey wrench, not only effort is also time-consuming.
Summary of the invention
The purpose of this utility model is exactly at existing situation, and a kind of easy to use and time saving and energy saving sub-connecting switch of transformer fastened tools is provided.
Its technical scheme is: comprise monkey wrench, it is characterized in that: the head and the handle of monkey wrench are rotationally connected by pin.
Also can be improved to: two grip blocks of monkey wrench head are fixedlyed connected with head, are provided with sliding block in the middle of two grip blocks, sliding block by screw thread be arranged on an adjustment screw on the grip block and be connected.
Also can be improved to: the middle part of described sliding block is connected with adjustment screw by screw thread, and both sides also are provided with the reinforcing screw.
Also can be improved to: the head at monkey wrench also is provided with the inner hexagon spanner cavity.
Also can be improved to: the spring stop piece that is fixed with anti-inner hexagon spanner slippage at the opening part of inner hexagon spanner cavity.
Effect of the present utility model is: the handle of monkey wrench is connected with head segmentation pin, can be folded into arbitrarily angled use, the reduced plan slewing area, avoid bushing shell for transformer, and adopt sliding block and adjustment screw to regulate spanner beginning size, easy to operate, time saving and energy saving, to be arranged in the spanner with the matching used inner hexagon spanner of adjustment screw, easy to carry and be difficult for losing.
Description of drawings
Accompanying drawing is the structural representation of present embodiment.
The specific embodiment:
With reference to accompanying drawing, present embodiment is that monkey wrench head 2 and handle 1 are rotationally connected by pin 3, two grip blocks of monkey wrench head 2 are fixedlyed connected with head, in the middle of two grip blocks, be provided with sliding block 4, sliding block 4 middle parts by screw thread be arranged on an adjustment screw 6 on the grip block and be connected, both sides also are provided with two and reinforce screw 5, also be provided with inner hexagon spanner 8 cavitys at monkey wrench head 2, be fixed with the spring stop piece 7 of anti-inner hexagon spanner 8 slippages at the opening part of inner hexagon spanner 8 cavitys.
