Abstract

The invention discloses a screw driver capable of receiving falling screws. The screw driver comprises a handle, a driver bar and a driver bit integrally formed. The screw driver is mainly characterized in that a circular truncated cone is arranged at the part, close to the upper end of the handle, of the lower part of the driver bar, a circular truncated cone-shaped cavity with the same axis as the circular truncated cone is arranged at the upper end of the circular truncated cone, a round through hole with the same axis as the circular truncated cone-shaped cavity is formed in the wall thickness part of the bottom end of the circular truncated cone-shaped cavity, and the circular truncated cone-shaped is arranged at the outer diameter end of the driver bar in a sleeving mode through the round through hole; a round rubber soft magnetic sheet ring matched with the circular truncated cone-shaped cavity is arranged on the bottom in the circular truncated cone-shaped cavity and is arranged at the outer diameter end of the driver bar in a sleeving mode, and the magnetism of the round rubber soft magnetic sheet ring faces upwards; the circular truncated cone is made of transparent organic glass or transparent rigid plastic. According to the screw driver, the screws falling accidentally can be received when screwed upwards, and the problem that finding of the screws falling accidentally is difficult can be solved. In the climbing work, the screw driver has the function of storing the standby screws.

Description

technical field [0001] The invention relates to the field of screwdriver manufacturing, more specifically to a screwdriver capable of catching dropped screws. Background technique [0002] A common screwdriver includes a handle, a knife shaft and an integrally formed knife head. When the screw is turned upward, it is easy to cause the screw to fall off, making it difficult to find. When working at heights, it is very troublesome to hold spare screws in the palm of your hand. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the prior art and provide a screwdriver capable of catching the accidentally dropped screw when the screw is turned upwards, so as to overcome the problem that it is difficult to find. When working at heights, it also has the function of storing spare screws. [0004] The technical solution of the present invention is to design and manufacture a screwdriver capable of catching dropped screws, incl...
