Abstract: A returning device of a wrench tool contains a body including a tool segment disposed on at least one end portion thereof and having two jaws, an engaging face of at least one of the two jaws including a recessed section in which a receiving groove with a stop rim is formed, the stop rim including a slot fixed on an eccentric position thereof; an auxiliary retainer inserted in the receiving groove and having a retaining portion; a positioning shaft including a front end connected at an eccentric position of a rear end of the auxiliary retainer and including a rear end extending out of the slot and allowing to prevent the auxiliary retainer from disengagement from the receiving groove; a resilient element used to push the auxiliary retainer so that the retaining portion extends out of the recessed section of the at least one of the two jaws.

Abstract: A burglarproof tool fitting holder device is formed with a side latch to tightly fasten a tool fitting for the effects of hanging show and protection against burglars. The device includes a tool fitting holder body and a burglarproof fixture unit. When the tool fitting holder body combines with the tool fitting in one, the fixing pedestal combines with the fixing cover plate of fixture unit in one via the two sides of the tool fitting to fasten the tool fitting. Further, ribs added in the inner fringes of the fixing cover plate and fixing pedestal is exactly wedged into the groove on the side of tool fitting to secure the tool fitting between the fixing cover plate and the fixing pedestal for effective protection against burglars.

Abstract: A meshing gyration tool comprising: a socket base; a socket clearance hole inside the socket base and surrounded by three first gripping surfaces, three second gripping surfaces and six third gripping surfaces for development of edge planes around the socket clearance hole wherein the third gripping surface is located between the first gripping surface and the second gripping surface for circular permutation of first gripping surface, third gripping surface and second gripping surface. The first gripping surface is a cambered surface. The second gripping surface is an angled surface consisting of two adjoining planes which form an obtuse angle. As such, the tool facilitates not only normally driving a nut or a bolt head but also screwing or unscrewing the nut or the bolt head with edges or corners worn out or damaged and further promotes overall convenience, practicability and market competitiveness.

Abstract: A ratchet wrench applicable to multi-size workpieces comprises: a wrench with a handle and a head wherein the head has a hollow handle hole in which there are two neighboring surfaces along its inner edge, a first support surface and a second support surface, and an accommodating space embedded into the handle; a support portion with a ratchet part and a resilient member wherein the ratchet part allows one end to be pivoted in the accommodating space and is provided with an arc-convex portion, which is within the hollow handle hole for a first working space developed inside, and the resilient member always exerts a resilient resistance on the ratchet part. As such, the ratchet wrench depends on a simple mechanism and is applicable to continuous screw operation of various screw fastening elements for excellent convenience and swiftness.
