Problems solved by technology

The company's production mode adopts the assembly line mode, which involves more than 100 commonly used models that need plugging. Among them, the operation time for installing the plugging screw station is too long, which seriously affects the production efficiency of the entire line
During the assembly process, there are mainly the following problems: 1. The plugging screw is a slotted slot that cannot be effectively matched with the screwdriver and is small in size and easy to fall off; 2. When tightening the plugging screw, the screwdriver head and the screw groove tend to be eccentric, making it difficult to fasten ; 3. The slow speed of manual screw installation affects production efficiency

Abstract

The invention provides a telescopic screwdriver head. A hole blocking screw is directly installed inside a telescopic sleeve. When working, the screwdriver can automatically rotate to be aligned with the hole blocking screw in the telescopic sleeve, and due to the fact that the hole blocking screw is located in the telescopic sleeve, the eccentric phenomenon of the screwdriver head and a straight-line-shaped groove of the screw is not caused. During screw fastening, the telescopic sleeve can stretch and shrink according to the installation depth of the screw, installation of the hole blocking screw is not affected, and the telescopic sleeve can achieve the stable effect before the screw is aligned with an installation hole.

Description

technical field [0001] The invention relates to a telescopic electric screwdriver. Background technique [0002] At present, in the repeater products produced by our company, in order to consider the versatility of the chassis, the heat sink of the chassis will reserve holes for mounting parts. In order to ensure good waterproof sealing of the equipment, plugging screws must be used for sealing and waterproofing. The company's production mode adopts the flow operation mode, involving more than 100 commonly used models that need plugging. Among them, the operation time for installing the plugging screw station is too long, which seriously affects the production efficiency of the entire line. During the assembly process, there are mainly the following problems: 1. The plugging screw is a slotted slot that cannot be effectively matched with the screwdriver and is small and easy to fall off; 2. When tightening the plugging screw, the screwdriver head and the screw groove are ea...
