Description

Technical Field

[0001] The utility model relates to the technical field of screw fastening, in particular to a tool for fastening screws of a television shell. Background Art

[0002] A TV is a device that uses electronic technology to transmit moving images and audio signals based on the visual persistence characteristics and visual psychology of the human eye, that is, a TV receiver. It is also an important broadcasting and video communication tool. The basic system of a TV consists of three parts: camera, transmission and display. During the installation of a TV, it is usually necessary to tighten the screws with a screw tightening tool.

[0003] In the process of tightening the screws of the TV casing, there is usually no adjustment function because the internal space of the TV casing is limited. Therefore, it is difficult to tighten the screws inside, which will cause serious inconvenience to the work and reduce work efficiency. In addition, the screws are prone to tilt and fall during installation, which is labor-intensive. Therefore, we propose a TV casing screw tightening tool. Utility Model Content
