Description

Small screw disassembling tool

Technical Field

The invention relates to the technical field of hardware equipment, in particular to a small screw disassembling and assembling tool.

Background

A screwdriver is a tool used to turn a screw into place and typically has a thin wedge shaped head that is insertable into a slot or recess in the head of the screw. The Beijing Jilu jin and Shaanxi north and the North Henan are called as 'screwdrivers', more calls in the North Henan, the areas of Jiangxi, Anhui, Hubei, Henan of the yellow river, the Shanxi Guanzhong and the like are called as screwdrivers, the areas of the middle and the west are called as screwdrivers, the areas of the Long triangular region are called as chisels, and the cross screw and the cross screwdriver are invented by Henli Philips in the thirties of the last century. First used in the assembly line of an automobile. The phillips screw and phillips screwdriver are also called philips screw and phillips screwdriver. In order to apply a small torque to a straight-line screw, people think that a groove is formed in the head of the screw, and the screw can be conveniently screwed and loosened by using a corresponding straight-line screwdriver. Firstly, once the straight groove of the screw head is damaged, the screw cannot be screwed out. The longer the length of the linear groove, the more easily it is damaged during screwing.

However, the existing small screw dismounting tool has the following disadvantages in the using process:

1. when the existing small screw dismounting tool is used for dismounting and mounting small screws in narrow spaces, the screws are easy to drop, and the use is very inconvenient.

2. The current little screw tool of dismouting is in the use, when tearing open, adorning little screw in narrow and small space, circuit mainboard is touched easily to the hand, causes the fastener to burn out, and tears open, when adorning hard very much, uses inconvenience very.
