Problems solved by technology

[0004] In addition, the existing screwdrivers require the operator to provide rotational force when screwing in and out of the fastener, and it often happens that the operator cannot screw out the fastener
Some fasteners are required for strength, the length is very long, and the number of turns to be screwed in and out is quite a lot, and the operator also needs to rotate the screwdriver for the same number of turns, which is laborious and laborious

Embodiment

[0017] Example: such as figure 1 As shown, a convenient screwdriver of the present invention includes a handle 1, and a power chamber is arranged inside the handle 1 near its head end, which is convenient for providing power for the positive and negative motor 5; the bottom end of the power chamber is fixed with a support plate 3 , it is convenient to fix the No. 1 storage battery 4 on the support plate 3; the No. 1 storage battery 4 is fixed on the support plate 3, and the No. 1 storage battery 4 can provide power for the positive and negative motor 5; The positive and negative motor 5 can drive the connecting rod 2 to rotate, and then drive the magnetic chamber 6 and the screwdriver head 9 to rotate, so that the screwdriver head 9 drives the screw to rotate, so as to realize screwing in and out of the screw; the output shaft of the positive and negative motor 5 passes through The coupling is connected to one end of the connecting rod 2 on the outside of the handle 1, and the...

Abstract

The invention discloses a screw driver convenient to use. The screw driver convenient to use comprises a grab handle, a connecting rod, a supporting plate, a first storage battery, a positive and negative motor, a magnetic chamber, a second storage battery, an electrification coil and a screw driver head. Because the positive and negative motor is arranged inside the grab handle. The connecting rod can be driven to rotate by the positive and negative motor so as to drive the magnetic chamber and the screw driver head to rotate, and then the screw driver heads drives a screw to rotate to achieve that the screw is screwed in or out. Then, the electrification coil is arranged in the magnetic chamber, and a small head end of the electrification coil is arranged inside the screw driver head; when the screw driver head needs to generate magnetic force, it is only needed that the electrification coil is electrified, the electrification coil can generate magnetic force and then can get attached to the screw driver head through the magnetic force, and the screw driver head is enabled to generate magnetic force therewith; and when no magnetic force is needed, electrification of the electrification coil is ended, the magnetic force of the electrification coil disappears, the screw driver head does not have magnetic force then, and usage is convenient.

Description

technical field [0001] The invention relates to a rounder machine, in particular to a convenient-to-use screwdriver. Background technique [0002] Screwdriver is a mechanical tool that is often used in daily life, and it is mainly used for the installation and removal of screws. The head shapes of common screwdrivers are mainly one-shaped, cross-shaped and Po-shaped. [0003] At present, the guide rods of many screwdrivers on the market have weak magnetism. In this way, the head of the screwdriver can absorb the screw during use, which not only facilitates the installation of the screw, but also prevents the screw from being unscrewed and dropped, and avoids the loss of the screw. However, for some special occasions, such as screw installation of precision electronic components, the use of a magnetic screwdriver sometimes has a certain impact on the performance of electronic components. Therefore, if the screwdriver can be designed to facilitate magnetization and demagne...
