Abstract

The invention relates to a universal joint which comprises a rod body, an adapter and an intervening part, wherein the bottom of the rod body is provided with a block body, and the top of the rod body is provided with a first driving part; the top of the adapter is provided with an accommodating groove, a second driven part is arranged on the bottom of the adapter, the peripheral wall surface of the upper section of the accommodating groove on the adapter is provided with a ring groove, a limited ring is arranged in the ring groove, and the block body is accommodated in the accommodating groove; the surface of the block body is provided with at least one groove, the surface of one side of the block body extends from top to bottom so as to form the groove; the peripheral wall surface of the accommodating groove on the adapter is provided with at least one corresponding groove, when the block body is placed in the corresponding groove, and the corresponding groove corresponds to the groove of the surface of the block body surface; and the at least one intermediate part is connected with the corresponding groove and the groove and positioned between the block body and the adapter, therefore, the effect of smooth operation is achieved by virtue of the intermediate part connected between the corresponding groove and the groove.

Description

technical field [0001] The present invention relates to hand tools, in particular to a universal joint used in hand tools. Background technique [0002] Most of the existing universal joints are formed by assembling two components. For example, US Patent Early Publication No. 2009 / 0288523 (the corresponding patent in Taiwan, China is M340894), which discloses a universal joint. This case discloses a first rod body and a second rod body, one end of the first rod body is a polygonal sphere, and one end of the second rod body is an accommodating groove for the polygonal sphere to be accommodated, and the accommodating The holding groove and the polygonal sphere are clamped face to face; the opening end of the containing groove is provided with a groove for a limiting member to be fastened and fixed, so that the polygonal sphere can be limited in the containing groove. [0003] When the above-mentioned existing universal joint is in use, the clamping relationship between the re...
