Abstract

The utility model discloses multi-angle socket spanner which comprises a fitting sleeve (1), supporting rods (2), a socket tube (3) and an operating rod (4), wherein the fitting sleeve (1) is closed or forms a ring shape with an opening, and the outer side of the fitting sleeve (1) is fixedly connected with the supporting rods (2); the socket tube (3) is sheathed on the supporting rod (2), and the socket tube (3) is movably connected with the operating rod (4). Since the fitting sleeve (1) is fixed with a plurality of supporting rods (2), when the socket spanner works, the fitting sleeve (1) can unscrew or tighten a tube joint without changing position; simultaneously, the operating rod can extend and shrink and the head can be bent, and thus, the applicability is reinforced with labor saving and convenient operation.

Description

A kind of polygonal box spanner

Technical field

The utility model relates to a kind of spanner, and especially a kind of applicability is strong, flexibly the polygonal box spanner in labour-saving.

Background technology

At present, engineering is of a great variety with mechanical wrench, the scope of application is wide, the part but these spanners also come with some shortcomings in use, the first: if the joint bottom on its pipeline is positioned on the working face, or joint bottom and working face gap are when very little, open-end wrench will repeatedly be shifted one's position and be changed sleeve, just can unclamp or fastening, not too convenient during use, and relatively require great effort; It two is: if when the joint on its pipeline is positioned at the end and plays plugging action, open-end wrench or box spanner need repeatedly be shifted one's position when unclamping or tighten up and the transfer sleeve equally, and be also not too convenient during use, and effort relatively.

Technology contents

Use the problem that has inconvenience and relatively require great effort in some cases at above-mentioned spanner of the prior art, the utility model provides a kind of applicability strong, flexibly the polygonal box spanner in labour-saving.

The purpose of this utility model is to realize like this, it comprises fitting sleeve, pole, telescopic pipe, action bars, described fitting sleeve inner chamber can be hexagon, square or toothed circle, fitting sleeve can seal, it also can be the shape of opening, be fixedly connected with pole on its fitting sleeve lateral surface, telescopic pipe is inserted on the pole, and telescopic pipe and action bars are movably connected.

Between described telescopic pipe and the action bars with being threaded its action bars outer end bending.

The utility model is owing to be fixed with a plurality of poles on fitting sleeve, thereby when the time with this box spanner work, its fitting sleeve is not shifted one's position, just can unclamp easily or the fastener tube joint, this action bars can stretch simultaneously, and head is bending again, thereby applicability strengthens, use more laborsavingly, operation easily.

The specific embodiment

Embodiment 1

In Fig. 1, all be hexagon inside and outside the fitting sleeve 1 on this polygonal box spanner, insertedly on the outside of fitting sleeve 1 be welded with three poles 2, telescopic pipe 3 one ends have internal thread, the other end and pole 2 activities are connected, and action bars 4 one ends are bent into circular arc, and the other end has a spindle nose that diameter is less, it is movably connected than enlarged diameter section and telescopic pipe 3 usefulness screw threads, and reach is at the 150-300 millimeter.

Embodiment 2

In Fig. 2, fitting sleeve 1 inner chamber on this polygonal box spanner is the opening hexagon, the outside is the open circles annular, insertedly on the outer side of fitting sleeve 1 be welded with three poles 2, telescopic pipe 3 one ends have internal thread, and the other end and pole 2 activities are connected, action bars 4 one ends are bent into circular arc, the other end has a spindle nose that diameter is less, and it is movably connected than enlarged diameter section and telescopic pipe 3 usefulness screw threads, and reach is at the 150-300 millimeter.

Claims
