A metal screwdriver with self-adaptive screw type of anti-skid wire

Abstract

The invention discloses a hardware screwdriver of self-adaptive screw type for non-slip wires, which comprises an self-adaptive mechanism for disassembling screws and a screw length compensation mechanism. The screw length compensation mechanism is arranged at the bottom of the self-adaptive mechanism; the self-adaptive mechanism It includes an extrusion sleeve for quick positioning, a limit ring, a disassembly disk, a central extrusion column, and a filling mechanism; the screw length compensation mechanism includes a compensation groove, a bearing sleeve, and a compensation spring. The self-adaptive screw of the anti-skid wire The hardware screwdriver of the model adopts the method of central positioning and filling around the screw to disassemble and install, on the one hand, it improves the scope of application of the screwdriver, that is, screws of different shapes can be disassembled and assembled by the same screwdriver, on the other hand, it is denser The filling can solve the problem that the screw cannot be disassembled caused by the slippery wire. At the same time, it can also use the spike to perform rust removal when it is in contact with the screw groove, sound wave filtering during disassembly, and prevent waste and falling objects from splashing around.

Description

technical field [0001] The invention relates to the technical field of hardware tools, in particular to a hardware screwdriver with an anti-slip thread self-adaptive screw type. Background technique [0002] Screw is a general term for fasteners, and it is also an indispensable industrial necessity in daily life. It can be seen everywhere in life and manufacturing, ranging from clocks and toys to aircraft bridges. Screws are mainly used for objects The physical and mathematical principles of the inclined plane circular rotation and friction force, a tool for step by step tightening the mechanism of the utensil. [0003] The installation and removal of screws is entirely dependent on the angular grooves or polygonal outer edges set at the ends, and is installed and removed with the use of a screwdriver, but the use of screws in daily life and industrial production The environment is different, some are hidden inside the equipment, and some ends are exposed in the external en...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a metal screwdriver with an adaptive screw type of anti-slip wire, which solves the problem that the screwdriver is severely restricted by the screw type when it is used, and the rusted screw is prone to slipping and cannot be disassembled. question
