Abstract

This utility model discloses a novel electric screwdriver with a modular design, including a screwdriver body and a handle mechanism. The screwdriver body includes a main body shell, a screwdriver head, and a drive assembly. The rear end of the main body shell has a T-shaped or dovetail-shaped locking groove, within which a conductive groove electrically connected to the drive assembly is embedded. The handle mechanism includes a handle housing containing a battery module and a control module. The housing has a slide rail boss that matches the locking groove, and a conductive plate on the boss. When inserted into the locking groove, the plate forms an interference contact with the conductive groove, achieving stable power supply. The contact surface between the conductive groove and the conductive plate is plated with a silver-nickel alloy layer to enhance oxidation resistance. The side of the locking groove has a positioning hole for fixed connection via a limit screw. This utility model has advantages such as convenient assembly and disassembly, stable conductivity, and strong vibration resistance, solving the problems of inconvenient maintenance, limited battery life, and poor versatility of traditional electric screwdrivers. It is suitable for various scenarios such as electronic assembly and mechanical repair.
