Novel wrench

Abstract

The invention discloses a novel wrench. The novel wrench comprises a screwing head, wherein a clamping head is fixedly connected to an inner cavity of the screwing head; the outer surface of the clamping head is rotationally connected with the inner wall of the screwing head; the top end of the clamping head penetrates through the outer surface of the screwing head and extends to the outside of the screwing head; a safety device is rotationally connected to the left side of a grip; and the right end of the safety device penetrates through an inner cavity of the grip and is rotationally connected with the right side of the inner wall of the grip. When a user uses the device to fasten a nut, the clamping head can rotate in the process of anticlockwise screwing the nut, after the nut fastening strength reaches the standard, the wrench is rotated, the clamping head can slip, the situation that the nut is broken due to the fact that the nut is excessively screwed is eliminated, the user does not need to manually rotate the nut, the process of rotating the nut by the wrench is extremely short, when the workload of the user is large, the wrench can save a large amount of manpower, and the working efficiency of the user is improved.

Description

technical field [0001] The invention relates to the technical field of hardware tools, in particular to a novel wrench. Background technique [0002] Because of the wrench's simple design, portability, and easy mass production, people usually use wrenches to tighten nuts in daily life. If the nuts to be tightened are bigger and the nuts are tighter, people need to use better wrenches. However, the wrench also has many shortcomings when screwing the nut. When the nut is just put on the screw, it is very inconvenient to tighten the nut with a wrench, so it is necessary to turn the nut by hand for a period of time. For fastening, the process of manually rotating the nut takes a long time. When the workload is heavy, manually rotating the nut also consumes a lot of manpower, which is very inconvenient. Contents of the invention [0003] The purpose of the present invention is to provide a new type of wrench to solve the problems raised in the above-mentioned background techno...
