Abstract

The invention discloses a multi-size screwdriver bit. At least two layers of screwdriver bit rods are sleeved with each other, and the screwdriver bit rods with different sizes correspond to screws with different specifications; the screwdriver bit rod located on the inner layer can slide in the axial direction; the connecting end of the screwdriver bit rod on the outermost layer is fixedly connected to a power rod; limiting holes are correspondingly formed in the side walls of all layers of screwdriver bit rods in a penetrating mode; when the limiting holes are aligned, limiting rods can be axially inserted, and the axial limiting effect on all layers of screwdriver bit rods is achieved; according to different insertion depths of the limiting rods, the screwdriver bit rods with different sizes can be moved out in the axial direction, and the screwdriver bit rods closer to the outer side can be moved out when the lengths of the limiting rods pulled out outwards are longer; and when the screwdriver bit rods with proper sizes are moved out, all layers of screwdriver bit rods synchronously rotate in the circumferential direction and are matched with screw heads for screwing operation. The multi-size screwdriver bit can be applied to screws with different specifications, and the size application range of the screwdriver bit is widened.

Description

technical field [0001] The invention relates to the technical field of hardware tools, and further relates to a multi-size screwdriver. Background technique [0002] At present, most of the connection methods between parts rely on screw locking. Depending on the material and size of the parts, the depth of the groove of the screw head is also different. At this time, when assembling large parts, different screws need to be matched, and the types of screws involved are relatively large. many. [0003] The bit is a screwdriver head that is installed on a hand drill or an electric hammer to screw the screw. When locking, it is necessary to change the type of the bit frequently, which brings inconvenience to the operation and reduces the efficiency. [0004] For those skilled in the art, how to improve the applicable range of the size of the bit is a technical problem to be solved at present. Contents of the invention [0005] The invention provides a multi-size screwdriver,...
