Abstract

The invention provides a screwdriver. The screwdriver comprises a screwdriver main body and an auxiliary structure, wherein the screwdriver main body can be matched with a screw to remove the screw; and the auxiliary structure is in gear connection with the screwdriver main body, and when the screwdriver main body is rotated to move in the first direction, the auxiliary structure can be controlledto move in the second direction opposite to the first direction through a gear, so that when the screwdriver main body disassembles the screw, the auxiliary structure can abut against the surface wherein a screw seat is positioned to enable the screwdriver main body to move stably. According to the screwdriver, the problem that the screw seat in the prior art is easy to damage during disassemblyis effectively solved.

Description

technical field [0001] The invention relates to the technical field of assembly and disassembly tools, in particular to a screwdriver. Background technique [0002] Such as figure 1 As shown, most of the models currently on the market need to use plastic screw seats to install and fix plastic parts due to the needs of scheme design or the structure of the body itself (such as the inconvenient fixing of nuts in some parts). In order to install the corresponding plastic parts on the vehicle body, the plastic screw seat can be fixed on the corresponding position on the vehicle body, and then the plastic parts can be installed on the corresponding position with the screw 1. Due to its material properties, the plastic screw seat is not as good as ordinary metal nuts in terms of torque and strength. If the torque is too large, the teeth may slip or the head may break. During long-term use or damage, the plastic parts should be disassembled from the vehicle body, which may cause ...
