Electric screwdriver with tool bits capable of being replaced rapidly

Abstract

The invention provides an electric screwdriver with tool bits capable of being replaced rapidly. The electric screwdriver with the tool bits capable of being replaced rapidly comprises a screwdriver body and a tool bit part arranged at the front end of the screwdriver body. The tool bit part comprises a plurality of secondary output shafts which are matched with a primary output shaft of the screwdriver body through a transmission gear set so that the primary output shaft can drive the secondary output shafts to rotate. The tool bit part further comprises a plurality of tool bit connecting rods which can move between a work position and a non-work position. When the tool bit connecting rods move to the work position, the tool bit connecting rods are matched with the secondary output shafts, and meanwhile the tool bits at the front ends of the tool bit connecting rods extend out of a shell. At the time, the tool bits can be used for screwing screws. When the tool bit connecting rods move to the non-work position, the tool bit connecting rods are separated from the secondary output shafts, and meanwhile the tool bits draw back into the shell.

Description

technical field [0001] The invention relates to the field of electric screwdrivers, in particular to an electric screwdriver capable of quickly replacing the cutter head. Background technique [0002] A power screwdriver is a power tool used for tightening and loosening screws, either in place or out of place on a tooling. However, since the screws have various specifications, the cutter head of the electric screwdriver also needs to be equipped with multiple replaceable cutter heads correspondingly to meet various needs during use. However, the replacement of the cutter head of the traditional electric screwdriver is cumbersome, and the replaced cutter head needs to be placed elsewhere, so that the electric screwdriver is separated from the cutter head, and the cutter head is easily lost. In addition, the length of the cutter head of the traditional electric screwdriver is fixed. If a cutter head of a different length is required, only another cutter head can be used, whic...

Problems solved by technology

However, the replacement of the cutter head of the traditional electric screwdriver is cumbersome, and the replaced cutter head needs to be placed elsewhere, so that the electric screwdriver is separated from the cutter head, and the cutter head is easily lost

In addition, the length of the cutter head of the traditional electric screwdriver is fixed. If a cutter head with a different length is required, only another cutter head can be used, which not only increases the production cost, but also brings a lot of inconvenience when using it.

[0003] In addition, when the traditional electric screwdriver clamps the bit, it mainly uses a three-jaw chuck for clamping. It takes a long time to replace the bit clamped in this way, which affects the work efficiency of the user.
