Multifunctional rotary screwdriver

Abstract

The invention relates to a multifunctional rotary screwdriver. The multifunctional rotary screwdriver comprises a handle and a screwdriver rod body, wherein the inner end of the handle is fixedly connected with the inner end of the screwdriver rod body, the handle comprises a base and a rotary bearing arranged inside a cavity of the handle, a groove is formed in the rotary bearing, a protrusion matched with the groove is arranged on the upper end face of the base, the screwdriver rod body is sleeved with a fixing sleeve, at least one notch is formed in the outer side of the fixing sleeve in the circumferential direction, an LED lamp bead is arranged at the joint between the inner end of the handle and the inner end of the screwdriver rod body, a power supply of the LED lamp bead is arranged inside the cavity of the handle, and a switch for controlling the LED lamp bead is further arranged on the handle. According to the multifunctional rotary screwdriver, the screwdriver rod body madeof a transparent light guide material is arranged, and the effect that light is accurately irradiated to a screw is similar to an optical fiber principle so that the working efficiency can be greatlyimproved; and the multifunctional rotary screwdriver has the advantages of being simple in structure, reasonable in design, convenient to use and capable of saving labor and saving time during screw tightening.

[0002] At present, there are two main types of screwdrivers for daily use in the market, depending on the source of power: one is manual screwdrivers, which are cheap and easy to carry, but they rely entirely on the wrist when used. Long-term use will cause wrist soreness and arm weakness, which will affect the work. continue; although the electric screwdriver is easy to use and saves physical strength, its use is limited; and when the light is dark or the screw is in a deep hole, it generally requires the other hand to hold an additional lighting tool to work accurately and normally. It greatly affects the production efficiency, and sometimes even brings certain safety hazards

Although some screwdrivers with self-luminous lighting devices have been invented, their light sources are mostly placed on the handle of the screwdriver, and they still cannot provide effective lighting in some deep hole environments.
