Screwdriver convenient to use

Abstract

The invention discloses a screwdriver convenient to use. The screwdriver comprises a screwdriver handle, a screwdriver bar and a screwdriver head, the screwdriver handle is composed of a fixed portion and a rotary portion, the screwdriver bar is connected with the rotary portion, the screwdriver head is arranged at the end of the screwdriver bar in an integrated mode, and the screwdriver is characterized in that grooves are symmetrically formed in the two sides of the fixed portion, a rod body is arranged at one end of each groove in a hinged mode, and a support rod is arranged between each rod body and the corresponding groove. According to the screwdriver, the structure is simple, the design is reasonable, the rod bodies are symmetrically arranged at the two sides of the fixed portion, so that it is facilitated for a user to use the screwdriver in a labor-saving, portable and convenient mode, by arranging LED lamp beads, it is facilitated to use the screwdriver under the circumstance of poor light, the application range is enlarged, by arranging protruding points on the screwdriver head, the slipping phenomenon can be effectively prevented, thereby the working efficiency can be raised, and the service life of a product can be prolonged.

Description

Technical field [0001] The invention belongs to the technical field of hardware tools, and specifically relates to a convenient screwdriver. Background technique [0002] A screwdriver is a tool often used in daily life and production. It is a tool used to turn a screw to force it in place. The screw is fixed or taken out in a rotating manner. There are mainly flat-blade screwdrivers and Phillips screwdrivers. Screwdrivers do not have round heads, because round heads do not produce twists. The word head is to ensure that there are twists, and the cross head can make the force distribution more even. [0003] Existing screwdrivers usually connect the bit on the handle. The structure of the screwdriver of this structure is relatively simple, but its function is single and its use is subject to certain restrictions. The length of the handle cannot meet the needs of use in a narrow space. The technical problem is that a screwdriver with adjustable handle length appears, but the existi...

Problems solved by technology

[0003] Existing screwdrivers are usually connected with the cutter head on the handle. The screwdriver with this structure has a relatively simple structure, but its function is single, and its use is subject to certain restrictions. The length of the handle cannot be used in a long and narrow space. Technical problem, there have been screwdrivers with adjustable handle lengths, but the existing screwdrivers usually do not have lighting equipment and cannot be operated in a dark environment. At the same time, the existing screwdrivers are especially difficult to screw when used The screws need to use a lot of force, which is time-consuming and labor-intensive, and the efficiency is low. In addition, the existing screwdrivers usually have smooth blades, and the phenomenon of "slipping" of the screwdriver often occurs during use, especially when the screw is too tight. When the original screwdriver torque is too small, the "slipping" phenomenon is more likely to occur, which not only affects the strength and time of screw loading and unloading, but also easily destroys the shape of the screw notch, affecting the next loading and unloading of the screw, and shortening the life of the screw. service life
