Claims

[Claims for Utility Model Registration] 1. Consisting of a hollow cylindrical socket receiver provided at one end of the handle, and a geared socket inserted into the socket receiver, the socket receiver is located on the inner periphery. A ring groove extending in the circumferential direction is recessed in the center of the surface, and at least one pair of upper and lower internal teeth are provided in a protruding position at a position separating the ring groove, so that the geared socket extends in the circumferential direction in the center of the outer peripheral surface. Along with providing a recessed ring support groove,
A plurality of pairs of upper and lower driving teeth that mesh with the upper and lower inner teeth are provided in protrusions at positions separating the ring support groove, and an elastic connecting member is inserted between the ring groove of the socket receiver and the ring support groove of the geared socket. An interlocking clutch type socket trench that rotates the socket receiver and the geared socket in two directions: the direction in which the axis is tilted in the circumferential direction, and the direction in which the socket is rotated in the forward and reverse directions. 2. The interlocking clutch type socket trench according to claim 1, wherein said elastic communication member is a highly elastic C-shaped ring. 3. The meshing clutch type socket trench according to claim 1, wherein the geared socket is formed such that its upper and lower end surfaces are shaped to effectively rotate an article to be tightened or loosened.
