Abstract

A self-rotating tool includes an inner tube, an outer tube and a spinning mechanism. The outer tube is sleeved on the inner tube so as to be movable between a compressed position and an uncompressed position along an axial direction of the inner tube. The spinning mechanism includes a screw rod, a screw seat, and a one-way bearing. One end of the screw rod is connected to the outer tube and the other end is inserted into the inner tube. An outer periphery of the screw rod is provided with a helical portion, and an inner periphery of the screw seat is provided with an abutting portion. The screw seat is sleeved on the screw rod so that the abutting portion is movable along the contour of the helical portion. The one-way bearing is sleeved on the screw seat and has an outer periphery connected to the inner periphery of the inner tube. When the outer tube moves to the compressed position, the inner tube can rotate relative to the outer tube. When the outer tube moves to the uncompressed position, the inner tube dos not rotate relative to the outer tube. Thus the tool can be used by the user to generate a rotation action by pushing.

Description

Tools with spin function

The present invention mainly discloses a tool, especially a tool with a spin function.

Please refer to the "Impact Spin Hand Tool" patent case of my country Patent No. I561346, which is an impact spin hand tool, including a hollow body, a first rod and a first elastic member. The hollow body includes a first limiting structure, and the first rod includes a spinning structure and a force-applying end housed in the hollow body, and a driving end exposed outside the hollow body, and the force-applying end has a second limiting structure. The first elastic member is located in the hollow body, and its two ends are respectively against the force-applying end and the first limiting structure. The second limiting structure is detachably limited by the first limiting structure. When the hollow body is connected to the first rod, the first rod is in the first position and compresses the first elastic member to store the elastic restoring force, and When the second limiting structure breaks away from the first limiting structure, the elastic restoring force drives the first rod to move to the second position, and the second position allows the spin structure to perform an impact spin action.

However, after the above-mentioned spinning action of the hand tool is completed, if you want to perform the spinning action again or use the normal mode to operate, you need to pause the operation and push the first rod back to the first position, which is inconvenient to use.
