Abstract

A screwdriver comprises a shaft barrel, a gear train installed in the shaft barrel, a shaft system installed on the gear train, a shifting ring installed outside the shaft barrel in a sleeving mode and a shell fixed outside the shaft barrel. A screwdriver rod body is driven to rotate through pressing, the rotation direction of the screwdriver rod body is controlled through shifting of a clutch spline shaft, screwing or unscrewing of a screw is achieved, rotation or stopping of the screwdriver rod body is achieved through shifting of a shifting ring and controlling of separation and reunion of a stopping claw and a stopping wheel, and the problem that large torque is needed when the screw is loosened and fastened is solved through fixing of the screwdriver rod body.

Description

technical field [0001] The invention relates to the field of mechanical tools, in particular to a screwdriver. Background technique [0002] Before the screw is tightened or after it is loosened, there is often a certain stroke. At this time, although the torque is not large, the screwdriver needs to be continuously rotated, which is inefficient and inconvenient to operate. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a screwdriver, which includes a shaft cylinder, a gear train installed in the shaft cylinder, a shaft system installed on the gear train, a dial ring sleeved outside the shaft cylinder, and a shaft fixed on the shaft. outer casing; [0004] By pressing, the shaft of the screwdriver is driven to rotate, by turning the clutch spline sleeve, the direction of rotation of the shaft of the screwdriver is controlled, and the screw is turned up or down, and by turning the ring, the clutch ...
