Description

Device convenient for screwing screw

Technical Field

The utility model relates to a screw appurtenance technical field particularly, relates to a device of conveniently twisting screw.

Background

In the current production, a large number of parts are assembled, connected and fixed through screws. When screwing the screw, a screwdriver is generally used. The screwdriver is a tool for screwing a screw to force the screw into place, and the working principle of a wheel shaft is utilized when the screwdriver is used for screwing the screw

However, in the field of machining, for a large-scale device, the number of screws in the device can be thousands of, and the device is operated by manpower only by a common screwdriver, which wastes time and labor and has low working efficiency. In addition, the existing method for installing the screw is to hold the screw by one hand, screw the screwdriver by the other hand, and then screw the screw into the installation position with force without a tool for clamping the screw. There are the following disadvantages:

1. the self-tapping screw is not stable when being held by hands, is easy to slide from a gap between fingers, and is not easy to mount.

2. When the self-tapping screw is installed, the screwdriver is easy to be separated from the screw, and hurts a hand holding the self-tapping screw, so that the self-tapping screw is unsafe.

In view of the above, the present inventors have invented a device for facilitating the screwing of screws.
