Abstract
A telescopic wrench includes an outer tube, an outer sleeve, and an inner rod. The first hole of the outer sleeve ring is fitted onto the outer tube, and the second hole of the outer sleeve provides peripheral contact with the rod section of the inner rod. The outer sleeve forms an external auxiliary fitting structure with the inner rod and outer tube. The telescopic wrench provides an improvement over known structures that are prone to loosening and noise during use. The telescopic wrench enhances the structural strength when subjected to operating forces.
