Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0019] Such as figure 1 , figure 2 As shown, the present invention provides a pressure-sensitive dual-combination magnetized screwdriver, which includes a handle 1 and a screwdriver head 2 located at the top of the handle, and also includes a light emitting device, which includes a switch 3, a lamp group 4, and The battery 5 is arranged in the handle, the light set 4 is arranged on the top of the handle 1 around the screwdriver head 2, and the switch 3 is a photoresistor. A photoresistor is a resistor made of the photoelectric effect of a semiconductor whose resistance value changes with the intensity of the incident light; the incident light is strong, the resistance decreases, and the incident light is weak, the resistance increases. When the hand holds the handle 1 and c...

Abstract

The invention provides a pressure sensitive and light sensitive combined magnetized screwdriver. The problem that in the prior art, operation with a screwdriver is not convenient or has potential risk in a dark environment is solved. Meanwhile, an electromagnet is arranged in a screwdriver head to prevent magnetism of the screwdriver head from being reduced. The electromagnet, a first pressure sensor, a light-sensitive resistor and a battery are connected with a control module. When the first pressure sensor receives a hand gripping strength signal and the brightness received by the light-sensitive resistor is within the specified value, namely when a lamp set is turned on, the control module synchronously conducts power of the battery to the electromagnet so as to magnetize the screwdriver head, and the service life of the screwdriver is prolonged.

Description

technical field [0001] The invention relates to the field of screwdrivers, in particular to a pressure-sensitive double-combination magnetized screwdriver. Background technique [0002] A screwdriver is a tool that fixes or removes a screw by rotation. There are mainly two types: one word (minus sign) and cross (plus sign). Then start turning the handle to tighten the screw. Screwdrivers are widely used in industry, construction and other industries, but when people work in the dark or in a backlit environment, it is often difficult to see the position of the screw, which makes the operation difficult. In order to solve this problem, people often need to free up a hand to hold a flashlight for lighting, and carry out one-handed operation, which is particularly dangerous because there is no third hand to hold on to the stairs when at a high place. Contents of the invention [0003] The invention proposes a pressure-photosensitive double-combination magnetized screwdriver,...
