Electric spanner

Abstract

The electric spanner has reducing motor set below the adjusting nut, the first gear connected to the rotation shaft of the reducing motor, the second gear connected to the adjusting nut and meshed to the first one, and rechargeable battery inside the handle cavity and connected to the charge circuit and connected to motor via DPDT switch. As the improvement of available spanner, the present invention may be used to replace available spanner and has its jaw adjusted via depressing the forward button or backward button slightly. It has simple structure and is practical, especially in oily condition and narrow space.

Description

technical field [0001] The invention relates to an electric wrench, which belongs to the technical field of hardware tools. Background technique [0002] The adjustable wrench currently on the market is one of the necessary tools for repairmen. When in use, the distance between the jaws of the wrench is adjusted by manually adjusting the adjusting nut of the wrench, so as to correspond to nuts of various specifications. In actual use, when repairing some For machines with a lot of oil pollution (such as motorcycles) or the space available for maintenance is too small, it becomes very inconvenient to adjust the nut. Sometimes, due to the misalignment of the gap between the tiger's jaws, some very important nuts are screwed down when they are pulled hard. Scrap, bring very big trouble and economic loss to the user. Contents of the invention [0003] The purpose of the present invention is to provide an easy-to-adjust distance between the jaws of the existing traditional wre...

Problems solved by technology

[0003] The purpose of the present invention is to provide an easy-to-adjust distance between the jaws of the existing traditional wrench, which is often inaccurate due to the difficulty in adjusting the distance between the jaws of the wrench when it is used in some specific situations, thereby easily causing related nuts to be screwed. An electric wrench that is easy to operate and the nut is not screwed

[0005] The present invention is an improvement to the structure of the existing movable wrench. It is composed of a rechargeable battery, a simple control circuit, a charging circuit, an economical and reliable decelerating motor and a transmission system on the relevant parts of the wrench. Using it to screw the nut can effectively solve the problem of the tiger's mouth. In order to prevent the nut from being screwed, when using this wrench, you only need to press the forward button or the reverse button lightly, and the motor that can rotate forward and reverse will drive the adjusting nut to rotate and adjust the distance between the wrench's mouth. It becomes very convenient if the space is large and the space is too small. The present invention has simple structure and strong practicability
