Safety protection device for long handle pneumatic screwdriver

Abstract

The invention relates to a safety protection device for a long handle pneumatic screwdriver. A protective sleeve (3) is arranged outside the long handle pneumatic screwdriver, an internal hexahedron is arranged at the rear end of the protective sleeve and matched with an external hexahedron arranged of a screwdriver handle (4), so that axial movement of the screwdriver handle in the protective handle does not exist, an internal circular shape is arranged on a position where the front end of the protective sleeve (3) exceeds a screwdriver in length, the internal diameter of the internal circular shape equals to the external diameter of a screw (7), and the internal circular shape is sleeved on the screw. When the safety protection device is used for assembling a long handle screw, due to the fact that the protective sleeve is matched with the screw, the screwdriver can not slip off, on one hand, the safety of operators is protected, and on the other hand, production efficiency is further improved. The safety protection device for the long handle pneumatic screwdriver is reasonable in structural design, simple in manufacturing, and capable of improving work efficiency, eliminating potential safety hazards, improving product quality and reducing production cost, and wide in application range and favorable for popularization and application.

Description

technical field [0001] The invention relates to the field of safety precautions for pneumatic tools during actual operation, in particular to a safety protection device for long-handle pneumatic screwdrivers. Background technique [0002] With the development of large-scale industrial production, manual work is gradually replaced by mechanization and automation, especially electric and pneumatic tools are more and more widely used in our production activities. Taking pneumatic wrench as an example, a worker in the assembly workshop of an enterprise To screw thousands of screws, the pneumatic wrench improves the work efficiency several times for this simple and repetitive operation. However, since the screwdriver head and the concave surface of the screw need to be completely matched, when assembling, put the screwdriver head into the screw groove, and turn the screw by turning the screwdriver. The rotation speed is faster due to the use of an electric screwdriver, and becaus...

AI Technical Summary

Problems solved by technology

However, since the screwdriver head and the concave surface of the screw need to be completely matched, when assembling, put the screwdriver head into the screw groove, and turn the screw by turning the screwdriver. Because the electric screwdriver is used, the rotation speed is faster, and because the screw is too long, when turning If the screw head is centrifugal, the screwdriver head will slip out of the screw concave surface and cause a safety accident or need to re-fit the screwdriver head with the screw concave surface, which greatly reduces the efficiency
