Abstract

The invention relates to an electric screwdriver. The electric screwdriver comprises a shell, a main shaft, a screwdriver blade box and a control mechanism. The main shaft is provided with an annular groove. The control mechanism comprises a first sleeve, a second sleeve, spherical beads and a third sleeve. The first sleeve is connected to the main shaft in a sleeving mode. The second sleeve is connected between the main shaft and the first sleeve in a sleeving mode. The spherical beads are arranged between the main shaft and the second sleeve, and part of each spherical bead is pressed by the second sleeve in the annular groove. The third sleeve is arranged inside the shell and connected to the main shaft in a sleeving mode, a through hole is formed in the third sleeve, and the spherical beads are arranged inside the through hole. The first sleeve can drive the second sleeve to move in the axial direction of the main shaft, and the second sleeve selectively presses or loosens the spherical beads in the movement process, and can drive the main shaft to move after the spherical beads are loosened. The control mechanism of the electric screwdriver is compact in integral structure and small in size, and the problem that an existing electric screwdriver with a built-in screwdriver blade box is large in size is solved.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to an electric screwdriver. Background technique [0002] Screwdrivers are widely used to disassemble and assemble various workpieces. The currently used screwdrivers generally include manual screwdrivers, electric screwdrivers and pneumatic screwdrivers. Among them, the electric screwdriver uses an electric motor instead of manual drive to install and remove screws. The existing electric screwdrivers include electric screwdrivers with a built-in bit box. The built-in bit box can provide multiple types of bits, and users can conveniently choose a suitable bit from the built-in bit box according to actual needs. working. [0003] The electric screwdriver with a built-in bit box needs to be equipped with a corresponding control mechanism. Through the interaction relationship with the bit box, the control mechanism can make the bit box provide suitable bits. However, the current electr...
