A constant velocity universal joint includes outer and inner joint members that transmit torque while allowing angular displacement via balls, a power transmission shaft connected to the inner joint member in a torque transmittable manner, and a detachable mechanism between the inner joint member and the power transmission shaft to detach the power transmission shaft from the inner joint member. The detachable mechanism includes a cylindrical member externally fit onto the power transmission shaft, spheres movable in a radial direction in the cylindrical member, and an annular member movable in an axial direction on an outer periphery of the cylindrical member. Locking claws are provided at an end of an inner joint member side of the annular member, and a locking groove is provided at an end of an annular member side of the inner joint member. The locking claws are fitted into the locking groove.

A driving tool with universal rotating structure includes a first drive joint member and a second drive joint member. The first drive joint member defines a compartment and at least one slot. The first end of the at least one slot includes is in communication with the compartment. The at least one slot extends through an outer periphery of the first drive joint member. The at least one slot includes a retaining member movably disposed therein. The outer periphery of the first drive joint member includes an enclosing ring disposed thereon. The enclosing ring is elastic and includes an inner periphery abutting against a side of the retaining member. The second drive joint member includes a head rotatably coupled to the first drive joint member. The head is disposed in the compartment. The head extends from a first end to a second end concavely along a second axis.

A universal joint includes a first joining structure and a second joining structure movably coupled to each other. The first and the second joining structures are movable relative to each other to an aligned position and an inclined position. The first and the second joining structures include a resilient member disposed therebetween. The resilient member has a first end retained on the first joining structure and a second end retained on the second joining structure.

Quick release mechanisms for auger type cleanout tools are described. The mechanisms enable engagement and disengagement of a handle to an auger without the use of separate retainers or fasteners. Also described are auger type tools and related methods of use utilizing the quick release mechanisms.
