A screwdriver for all-material screws with a magazine

Abstract

The invention discloses a screwdriver with a nail storage box and suitable for screws of all materials. The screwdriver comprises a tightening unit, a nail storage unit and a connecting line. The tightening unit comprises a screwdriver body; the screwdriver body comprises a handle, a connecting part and a tightening rod; an elastic clamp plate is arranged on each of the front side and the rear side of the tightening rod; a stepped hole is formed in the screwdriver body; and a mandrel is arranged in the stepped hole. A first spring is arranged between the mandrel and the handle; and a cylindrical pin which is matched with first sliding grooves in the tightening rod and second sliding grooves in the elastic clamp plates is arranged at the left end of a third shaft. The nail storage unit comprises a plurality of nail storage cylinders; an inserting block is arranged on the rear side of each nail storage cylinder; an inserting groove is formed in the front side of each nail storage cylinder; and a groove opening is formed in each of the left side and the right side of each nail storage cylinder. The screwdriver can clamp the screws of all materials, can finish the whole process from clamping to tightening by a single hand, and is very suitable for the working condition of small space.

Description

technical field [0001] The invention relates to a screwdriver, in particular to a screwdriver with a nail storage box suitable for screws made of all materials. Background technique [0002] In the process of daily electric power construction, screwdrivers are frequently used tools. In order to facilitate installation and tightening, current screwdrivers are generally magnetic. But even so, in the actual construction process, the screw does not conduct magnetism. At this time, only one hand can hold the screw, and the other hand can fasten it with a screwdriver. However, in the process of electric power construction, the general installation space is relatively narrow, which brings inconvenience to the construction. [0003] In response to this problem, the patent No. 201610369413.6 discloses a screwdriver that can hold screws of any material. Although the screwdriver can hold screws of any material, it is not necessary to hold the screw with one hand during the fastening p...

AI Technical Summary

Problems solved by technology

But even so, in the actual construction process, the screw is not magnetically conductive.

At this time, you can only hold the screw with one hand and tighten it with a screwdriver with the other hand. However, during the electric power construction, the general installation space is relatively narrow, which brings inconvenience to the construction.

[0003] In response to this problem, the patent No. 201610369413.6 discloses a screwdriver that can hold screws of any material. Although the screwdriver can hold screws of any material, it is not necessary to hold the screw with one hand during the fastening process. But still there is the problem of inconvenient operation, this is because the jacket needs to be lifted in the process of use to clamp the screw, so in the process of tightening the screw, the jacket needs to be lifted all the time, especially the screw In the first few turns of fastening (the screws are not connected reliably at this time), it is inconvenient for construction personnel to operate while holding the jacket and turning the screwdriver

[0004] In addition, in the process of daily construction, there is also the problem of inconvenient storage of screws. Generally, screws of different specifications are required during construction, and these screws are generally placed in a storage box in a concentrated manner. Need to choose different specifications of screws according to the needs

For experienced old employees, sometimes it can be judged by naked eyes, but it is more difficult for new employees

Even if bolts of different specifications are placed in different categories, for screws that cannot conduct magnetism, even if a screwdriver that can hold screws of any material disclosed in Patent No. 201610369413. The process also requires two hands to complete, it cannot be done with one hand, and the efficiency is low
