Description

Technical Field

[0001] The utility model belongs to the technical field of fastener disassembly, and in particular relates to a threaded fastener disassembly tool. Background Art

[0002] There are many kinds of tools for removing threaded fasteners. Different tools can be selected according to the specific type, size and removal environment of the fastener. The screwdriver is one of the most common thread assembly and removal tools, also known as a screwdriver. It is often used to remove screws. The cross screwdriver is a common type. During the removal process, the blade of the screwdriver should be completely consistent with the groove of the screw to avoid damaging the screw thread or the screwdriver head.

[0003] The threaded fastener removal tools currently on the market have the following problems when used:

[0004] 1. In the actual use of traditional threaded fastener removal tools, screwdrivers are usually used to remove screws. Screwdrivers are divided into one-piece structures and magnetic-bit structures. Although the one-piece structure has higher strength, it is not convenient to repair when the bit is damaged. Although the magnetic structure is convenient for repair, its connection strength is weak. Therefore, when using a magnetic detachable screwdriver, it is easy to break the bit if the force is too strong, which is inconvenient to use.

[0005] 2. When using most threaded fastener removal tools, workers are often required to hold the handle for removal. Holding the handle for a long time makes it inconvenient to apply force, and the handle cannot be held well to apply force during use. Utility Model Content
