Problems solved by technology

Because the electric wrench is dangerous, once the parents do not notice that the child is playing with the electric wrench and give the child enough help, if the electric wrench can be opened by the child at will, it will cause harm to the child. The electric wrench is a safety hazard for children
In addition, due to the relatively high cost of the electric wrench, it is necessary to improve the versatility of the electric wrench to make the electric wrench more popular.

Abstract

A detachable electric wrench, which includes a handle device and an operating device, the operating device is detachably installed on the handle device, wherein the user can operate a fastening device by means of the operating device through the handle device means to install or remove said fastening means. Users can install the operating device of different specifications on the handle device to improve the versatility of the detachable electric wrench. For example, the operating device can have a hexagonal structure or a notch structure to use the detachable electric wrench. An electric wrench can be used to install or remove the fastening devices of different specifications, so as to reduce the cost of using the detachable electric device.

Description

technical field [0001] The invention relates to a mechanical tool, in particular to a novel electric wrench. Background technique [0002] A wrench is a common installation and removal tool in which the wrench utilizes the principle of leverage to enable the user to turn bolts, screws, nuts, and other threaded fastening devices with relative ease. In the past, wrenches were all manual tools with a relatively simple structure. When using them, users need to apply force to turn the fastening device with the help of a wrench. In order to reduce the workload of users and improve work efficiency, electric wrenches have been developed and popular now. Compared with the manual wrench, the electric wrench uses a motor to drive the fastening device to rotate. Because the electric wrench is dangerous, once the parents do not notice that the child is playing with the electric wrench and give the child enough help, if the electric wrench can be opened by the child at will, it will caus...
