Description

Technical Field

[0001] This utility model relates to the field of terminal block processing technology, specifically a terminal block screw tightening device. Background Technology

[0002] Terminal blocks are commonly used components in electrical connections, using screws to securely connect wires to terminals. During the installation, maintenance, and circuit troubleshooting of terminal blocks, it is necessary to frequently tighten or loosen the terminal block screws.

[0003] Currently, the tightening and loosening of terminal block screws is mostly done manually with a traditional screwdriver. When operating manually, it is difficult for the operator to accurately control the force applied. If the force is too small, the screw may not be tightened properly, resulting in poor circuit contact and affecting the normal operation of electrical equipment. If the force is too large, the screw may be stripped or the terminal block may be damaged, increasing maintenance costs and wasting a lot of time, which affects work efficiency.

[0004] Therefore, we urgently need to provide a terminal block screw tightening / loosening device. Utility Model Content
