Screw assembling and disassembling assistor

The screw assembling and disassembling assistor comprises a mounting base, a center gear and planetary gears, the center gear and the planetary gears are rotationally arranged in the mounting base, and the planetary gears are arranged in an array mode in the circumferential direction of the center gear and engaged with the center gear; a power input part used for driving the sun gear to rotate is arranged in the sun gear, a screwdriver blade coaxial with the planet gear is arranged in each planet gear, and the power output end of each screwdriver blade extends out of the mounting base. Synchronous assembly of the screws can be achieved, collision and abrasion of threads between the screws and the screw holes are avoided, and the connecting strength and the assembly efficiency are improved. 本发明公开了一种螺丝装卸辅助器，包括安装座，以及转动设置在所述安装座内的中心齿轮和行星齿轮，所述行星齿轮绕所述中心齿轮的周向阵列设置，且与所述中心齿轮啮合；所述中心齿轮内设有用于驱动其旋转的动力输入件，每个所述行星齿轮内设有与之同轴设置的螺丝刀头，所述螺丝刀头的动力输出端伸出所述安装座。本发明能够实现螺丝的同步装配，避免螺丝与螺孔之间螺牙的磕碰和磨损，提升连接强度与装配效率。
