What should I do if the steel wire of the anti-theft pull box doesn't spring back or springs back weakly?

If the steel wire of the anti-theft pull box does not spring back or springs back weakly after being pulled out, you can troubleshoot and handle the problem using the following steps:

Check the wire winding: First, open the pull box and check if the internal steel wire is neatly wound. Sometimes, tangled or twisted wire can cause the pull box to not spring back effectively.

Lubricate the pulleys and mechanical parts: If there is friction in the pulleys or other mechanical parts inside the pull box, try using a lubricant to reduce friction.

Check the spring: The pull box usually has an internal spring responsible for the return force. If the spring is old or damaged, it needs to be replaced. You can open the pull box to check if the spring is working properly.

Clean dust and debris: Dust or debris inside may affect the normal operation of the pull cable, so it can be cleaned.

Check the connecting parts: Ensure that all connecting parts are not loose or detached, and may need to be re-secured.

Replace parts: If the problem persists after the above steps, consider replacing the damaged parts or the entire pull box.

If the steel wire of the anti-theft pull box does not spring back or lacks strength, the core reasons are fatigue breakage of the internal spring, corrosion and jamming of the steel wire rope, or obstruction by foreign objects. It is recommended to seek professional help to avoid further damage.
