Problems solved by technology

Screws often fall to the ground. Since there are outlets for cables and wire trenches everywhere in the switchboard, most of the screws that fall on the ground fall into the exits of the cable trenches and cannot be picked up again, which brings many obstacles to the maintenance personnel.
During the maintenance of mechanical equipment, screws will fall into narrow gaps or inside the mechanical equipment if they are not careful, which will bring safety hazards to the operation of mechanical equipment in serious cases

Embodiment Construction

[0033] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0034] The invention discloses a screwdriver, which is a hardware tool. The screwdriver has the function of preventing the screw from dropping after improving the existing screwdriver.

[0035] Screwdriver of the present invention, as figure 1 , figure 2 , image 3 As shown, it is an improved design of a screwdriver with a handle part 1 and a cutter body part 2, and a sleeve assembly with a cutter head sleeve 3 and a sliding sleeve 4 is arranged on the cutter body part 2 of the screwdriver. Wherein, the sliding sleeve 4 is fixedly connected to the lower end of the handle portion 1 at the top, and the cutter head sleeve 3 is sleeved under the sliding sleeve 4 . The sliding sleeve 4 is used to drive the screwdriver to move back and forth to install and disassemble the screw, and the lower end of the bit sleeve 3 can clamp and support the screw...

Abstract

The invention relates to a screw driver, and belongs to the technical field of hardware. The screw driver comprises a screw driver body with a handle part and a screw driver body part, a sleeve assembly with a screw driver bit sleeve and a sliding sleeve is further included, one end of the screw driver bit sleeve is a screw in-out end, the other end of the screw driver bit sleeve is a sleeve end provided with a first clamping part protruding outwards from the surface, the screw in-out end of the screw driver bit sleeve is a conic shell provided with a screw in-out opening in the side face, oneend of the sliding sleeve and the lower end of the handle part are fixed, the other end of the sliding sleeve is provided with a second clamping part protruding inwards, and a first compressed springis arranged in the sliding sleeve; and the sleeve end of the screw driver bit sleeve is connected into the sliding sleeve in a sleeved manner, and the first clamping part is located on the inner sideof the second clamping part of the sliding sleeve. The screw driver is reasonable in structural design, and the problem about time and force waste generated by installing and demounting due to frequent falling of screw spikes when a worker installs and demounts the screw spikes can be effectively solved. By means of the screw driver, operation time can be saved, the working efficiency is improved, and the very good using performance is achieved.

Description

technical field [0001] The invention relates to a screwdriver and belongs to the technical field of hardware tools. Background technique [0002] The screwdriver is one of the most frequently used tools in the daily equipment maintenance and installation process. Whether it is mechanical equipment or electronic power equipment, there are often a large number of screws that need to be disassembled or installed with a screwdriver. [0003] There are many problems with screwdrivers in regular use, and every maintenance personnel has experienced the situation of dropping screws or installing screws in a narrow place that is time-consuming and labor-intensive. For example, when disassembling the relays, voltmeters, signal lamps, resistors and other terminal strips of the equipment or disassembling them. Due to frequent disassembly, installation, unscrewing, screw tightening or disassembly and measurement of terminal screws due to maintenance. Screws often fall to the ground, be...
