Benefits of technology

[0012]It is one object of the present invention to provide a socket adapter for a ratchet wrench or a torque wrench that the metal elastic wire thereof is stably positioned by not only fitting the groove of the hexahedral engaging portion but also clasping the aperture on the groove surface to avoid sliding along the groove so that the first and second bends thereof can be invariably retained at the preset positions to ensure the fastening effect.
[0013]It is another object of the present invention to provide a socket adapter that can be assembled or disassemble with a ratchet wrench or a torque wrench easily by reason of the elastic flexibility of the metal elastic wire thereon. Since the metal wire has its open end freely extendable while the hook portion at the other end clasping said aperture, the same is therefore flexible to facilitate assembling and disassembling works smooth and effort-saving.
[0014]It is still another object of the present invention to provide a socket adapter that can be safely fastened to a ratchet wrench or a torque wrench under the effect of a three-point fastening system regarding to the first bend, second bend and the edge of the hexahedral engaging portion where a relevant resultant forces acts on.
[0015]A further object of the present invention is to provide a socket adapter with the metal elastic wire being easily formalized. The accurate meas

Example

[0029]As shown in FIGS. 5 and 6, the socket adapter for a ratchet wrench or a torque wrench according to the present invention primarily comprises:

[0030]a hexahedral engaging portion 40, having six vertices 41 and six edges 42, and further comprising an annular groove 43 with an aperture 44 on the groove surface 431; wherein the aperture 44 is provided corresponding to one of the vertices 41 of the hexahedral engaging portion 40; and a socket 50 attached to the bottom of the hexahedral engaging portion 40, interiorly having a hexahedral hole 51, a retaining edge 52 around the top end of the hexahedral hole 51 and a round hole 45 inside the hexahedral engaging portion 40 led to said hexahedral hole 51; and

[0031]a metal elastic wire 60 accommodated in the groove 43 of said hexahedral engaging portion 40 which comprises a first elastic section 61 with an open end 62 and connected to a second elastic section 64 through a first bend 63 and the second elastic section 64 further connected to
