Abstract

A socket spanner comprises a handle, at least one socket unit 101 and means for drivingly and detachably connecting the handle and the socket unit, and is characterised in that the socket unit is in the form of a tubular sleeve having multi-facetted sockets 102, 103 extending inwardly from the ends of the sleeve, for receiving differently sized multi-faced nuts, and in that the said means comprises a non-circular shaft 105 supported by the handle and a correspondingly shaped non-circular hole 104 formed in the tubular sleeve and opening into each multi-facetted socket. <IMAGE>

Description

SPECIFICATION Two-terminal sleeving BACKGROUND OF THE INVENTION: Subject design lies in the provision of multifaced sunk-in texture, differing in specifications, on both ends of the sleeving, with a square hole provided between the two multifaced sunk-in texture, to facilitate coupling with the sleeving spanner, so that a particular specification is rendered and matched by directional commutation in use.

SUMMARY OF THE INVENTION: The structure of an conventional sleeving usually takes the form of a cylinder, with one end structured to yield multiple sunk-inconfi- guration to facilitate accommodation of coupling nuts or screwheads, the other end complete with square holes to facilitate coupling with sleeving spanner, these sleevings, differing in size and specifications together will form a sleeving set, for use, each sleeving set as such requiring much materials and production costs, in addition to inconvenience of taking, so the subject design provides instead to have a sleeving processed to yield multifaced sunk-in textures, differing in specification, on both ends thereof, with a section of square holes for sleeve spanner driving provided in middle to facilitate coupling with the square head drive head of the sleeving spanner, characterised in reduction of weight, of production costs and convenience of application.

BRIEF DESCRIPTION OF THE DRA WINGS: Figure 1 is a three-dimensional perspective of the subject two-terminai sleeving.

Figure 1-1 is a cross-section view of one embodiment of the subject two-terminal sleeving.

Figure 1-2 is an Illustrative view of the relay rod incorporated in the subject two-terminal sleeving, and Figure 1-3 is an Illustration of one embodiment of the two-terminal sleeving structured hereunder.

DETAILED DESCRIPTION OF THE INVENTION: Sleeving spanner sets have long been appreciated particularly because of its reliability and convenience features, as is well know, a sleeving spanner set has to be composed of specifications differing in stair scale dimensions, so that as a rule the sleevings in a sleeving spanner set will have each processed independently and for selection before they are put together for use.

We proceed with description of the subject invention by referring in particular to a nonlimiting embodiment as follows: The subject design provides for a multifaced sunk-in textures, differing in specifications, on both ends of the sleeving, with a square hole reserved inmiddle to accommodate coupling with the sleeving spanner drive rod, meat for joint transmission, as would be better seen in embodiments depicted in Fig. 1 and Fig. 1-1 respectively, in structure it is composed of a hollow-set, cylindrical structure 101, characterised in:: -the provision of muti-faced sinking texture 102, 103, of different specifications, inside both ends of the cylinder, each face parallel with each other, said difference including specificational differences between metric and imperial units as regards screw nut sets, both ends can be of the same sustem, or one of one system, the other of the other system, metric or imperial.

-the provision of middle section of which the projection of its area is enclosed in the multi-faced square hole, for coupling with the square shaped terminal of the sleeving spanner drive rod.

In further applications, to increase its convenience feature, an extension rod like that shown in Fig. 1-2 may be incorporated, having a square internal texture 107 on one end.

to accommodate coupling with the square shaped terminal 108 of the sleeving spanner drive rod.

An example of application of the subject sleeving is as shown in Fig. 1-3, the materials as used permits one-piece embodiment owing to the common employment of a square shaped drive section, thereby saving of materials and the weight of the assembly, this will allow for increased production speed accordingly, as approximate sizes can be integrated in use, it permits selective use where both metric and imperial systems are involved in the size, and further, both ends processed to the size pertiment in special applications such as of machimery.

Accordingly, the convenience and economy possible through the present invention is beyond doubt, a new idea in substance, it merits being deemed an invention and honored as such, we suppose.

CLAIMS:

1. A socket spanner comprising a handle, at least one socket unit and means for drivingly and detachably connecting the handle and the socket unit, characterised in that each socket unit is in the form of a tubular sleeve having a multi-facetted socket extending inwardly from each end of the sleeve, for receiving differently sized multi-faced nuts, and in that the said means comprises a non-circular shaft supported by the handle and a correspondingly shaped non-circular hole formed in the tubular sleeve and opening into each multifacetted socket.

2. A socket spanner characterised in that the non-circular shaft and corresponding hole are square.
