Abstract: A torsional force structure of a ratchet device which includes a body having a head portion at an end of the body. The head portion has a space which is composed of a first recess and a second recess. A socket member is fitted in the first recess and having a plurality of teeth. A ratchet member is fitted in the second recess and provided at two ends thereof with two wedge portions configured to be fitted in an angular region between the inner wall of the space and the socket member. When the triggering rod is first adjusted to move the ratchet member to make one of the wedge portions of the ratchet member fit in the angular region and the the socket member is rotated, the wedge portion of the ratchet member will be forced to be tightly fitted in the angular region thereby enabling the socket member to provide a positive rotating force.

Abstract: A ratchet wrench is disclosed. The ratchet wrench is characterized in that the head portion has a tool connector cavity, and has a ratchet cavity adjacent to one side of the handle for communication with the tool connector, the ratchet block is positioned within the ratchet block cavity which can automatically move forward, the top face of the head portion corresponding to the top edge of the ratchet cavity is a notch for engaging with a covering plate; the middle section of the external edge is a tool connector is formed into a position-limiting circular slot, and the ratchet block having a ratchet wall with ratchet teeth is provided with position-limiting block which can correspondingly engage with the circular slot, and the top face of the ratchet block is protruded with a trigger rod passed through the covering plate, and the center of the covering plate is a corresponding T-shaped trigger recess, thereby a ratchet wrench is obtained.

Abstract: An improved structure of a ratchet wrench is disclosed. The ratchet wrench comprises a handle and a sleeve module at one end thereof, characterized in that the sleeve module is formed as a circular mount at the end portion of the handle, and the inner diameter of the circular mount is protruded with an urging edge, and the urging edge is provided with a sleeve having a ratchet face at the external circumferential edge, the handle, corresponding to the circular mount, is provided with an inter-communication crescent-shaped slot and the rear side of the crescent-shaped slot is extended with a cavity, a crescent-shaped ratchet block is located within the crescent slot, and the teeth and curvature of the crescent-shaped ratchet block and the ratchet face are corresponding to each other, a spring having restoration force is located between the crescent ratchet block and the cavity, thereby an improved ratchet wrench with a greater torque is obtained.

Abstract: An improved structure of the wrench is disclosed. The wrench relates generally to the end of the handle which is mounted with an open jaw module. The open jaw module has an end protrusion of the handle relatively provided with a smaller path of an insert lever, wherein and an open jaw is mounted. The end of the open jaw is formed into an insert recess of the inset lever. In accordance with the above mentioned specific structure design, the user will may change the size of the open jaw according to his/her size requirements.
