AI Technical Summary
The existing method of fixing the telescopic rod of the paint roller is prone to loosening, which leads to the risk of retraction. Paint can easily flow and come into contact with the skin of construction workers, affecting work efficiency and causing injury.
A telescopic rod structure including a handle, first and second telescopic rods, and a connector is designed. The rod body is locked by a detachable connecting sleeve, a pressing rod, and a return spring. A protective device is provided on the second connector to prevent paint from dripping.
It achieves stable adjustment of the telescopic pole and effective protection of the coating, improving work efficiency and protecting construction workers by preventing the coating from coming into contact with their skin.
