Problems solved by technology

[0002] Screwdrivers commonly used in real life have the problems of simple structure and single function
When the screw is near the vertical intersection line between the fixed surface and the wall, the screwdriver is hindered by the wall and cannot be disassembled
Also at night or in the dark, the screwdriver cannot locate the screw
The combined screwdriver can meet this situation, but it is inconvenient to carry and has the disadvantages of low utilization efficiency

Embodiment Construction

[0009] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0010] The present invention is: as figure 1 As shown, the flashlight power supply 10, the test pen neon tube 17, and the current limiting resistor 18 are located inside the handle, and are isolated by an insulating plate 20. One end of the working rod 22 forms a rotating pair with the working rod 1 through a hinge 23, and the sliding sleeve 2 is used for fixing the hinge. The other end of the working rod 22 is fixedly connected to the handle head 21 through the gasket 5 and the screw 6. The four LED lights 3 are located in the handle head 21, and the handle head 21 is fixedly connected to the handle sleeve through the screw 4. The end of the handle is connected to the handle head 21. The metal nut 14 is connected by threads.

[0011] During use, press the button switch 7, the internal return spring 9 is squeezed, the contacts 8 at both ends are connected to the wir...

Abstract

The invention relates to a detachable screwdriver flashlight circuit part and the electric test pen part which are detachable, easy to install, convenient to carry, integrate multiple functions, and can realize the functions of turning head, lighting and electric test pen. , The power supply part and the LED light part in the handle realize the lighting function, which ensures that the tool can be operated in a bright environment. The working rod is hinged, which can realize the 180-degree rotation of the cutter head, and has a wide range of applications. According to actual requirements, the hexagonal rod can be added to realize the length of the knife body, and it can also be matched with different types of knife heads. It has the function of electroscope pen to reduce the trouble of changing the tool, and the magnetic device is set in the hexagonal groove of the working rod to prevent the tool head from falling off during use.

Description

(1) Technical field [0001] The invention relates to a novel multifunctional screwdriver, in particular to a multifunctional screwdriver capable of turning heads, illuminating and measuring electricity. (2) Technical background [0002] Use the screwdriver ubiquitous structure simple in real life, the problem of single function. When the screw is near the vertical intersection of the fixing surface and the wall, the screwdriver is hindered by the wall and cannot be disassembled. In addition, at night or in the dark, the screwdriver cannot locate the screw. Combined screwdrivers can satisfy this situation, but they are inconvenient to carry and have the disadvantages of low utilization efficiency. (3) Contents of the invention [0003] The purpose of the present invention is to provide a detachable screwdriver which is easy to install, convenient to carry, integrates multiple functions, and can realize the functions of head turning, lighting and electroscope pen. [0004]...
