Embodiment Construction
[0035] The application will be described in further detail below in conjunction with the accompanying drawings.
[0036] refer to figure 1 The present application provides a device for preventing nuts from falling off for an electric wrench. The electric wrench 1 includes a body 11 and a rotating head 12 arranged on one side of the body 11. The outer contour of the rotating head 12 is circular, and the inner contour is a regular hexagon. The length of the swivel head 12 is greater than the thickness of the nut, and there are multiple groups of anti-dropping devices 2 along the axis direction of the swivel head 12, and the distance between two adjacent sets of letting go devices is equal to the thickness of the nut. When the electric wrench 1 is working, the rotating head 12 is set on the nut to be loosened or tightened, and the body 11 can drive the nut to rotate through the rotating head 12. When the nut is loosened, the anti-falling device 2 inside the rotating head 12 can ...

The application relates to the field of wrenches, in particular to a device for preventing nuts from falling off for an electric wrench. The electric wrench includes a body and a rotating head arranged on the body to cooperate with the nut. The length of the rotating head is greater than the thickness of the nut. The anti-falling device includes The installation head is evenly arranged inside the side wall of the rotation head along the circumference of the rotation head. The distance between the side of the installation head away from the body and the end surface of the rotation head is less than the thickness of the nut. The end of the installation head close to the central axis of the rotation head is provided with a section The shape of the tenon is a right-angled triangle. One right-angled surface of the tenon is fixedly connected with the installation head. The slope of the tenon is set away from the body. The side of the installation head away from the axis of the rotating head is provided with a device that can drive the installation head to move in a direction close to the central axis of the rotating head. The elastic member has the advantages of reducing the pollution to the environment and reducing the possibility of people being injured by nuts.
Description
technical field [0001] The present application relates to the field of wrenches, in particular to a nut drop prevention device for an electric wrench. Background technique [0002] At present, an electric wrench is a wrench powered by a power supply or a battery, and is used to screw in or loosen nuts. [0003] In the related art, the electric wrench includes a body and a rotating head arranged on the body that can rotate around its own axis, and the rotating head is adapted to the nut; after the nut is loosened by using the electric wrench, the loosened nut will follow the movement of the electric wrench. The swivel head is disengaged from the mounting position of the nut together, thus completing the process of loosening the nut. [0004] In view of the above related technical solutions, the inventor found that after using the electric wrench to loosen the nut, people will involuntarily swing the rotation of the electric wrench downward, so that the nut inside the rotatin...
