Abstract

A socket spanner comprises a telescopic outer pipe and a telescopic inner pipe. The telescopic outer pipe is a long cylindrical pipe fitting. One end of the telescopic inner pipe is connected to the telescopic outer pipe. The other end of the telescopic inner pipe is of a corner structure with a right-angle elbow pipe. One end of the right-angle elbow pipe is connected with a transverse telescopic pipe in a sleeved mode. One end of the transverse telescopic pipe is connected to the right-angle elbow pipe. The other end of the transverse telescopic pipe is provided with a rotating head. The rotating head is in a rod shape or a cylindrical shape. The rotating head and the transverse telescopic pipe are connected through a hinge pin. The other end of the rotating head is provided with a sleeve. The telescopic outer pipe and the telescopic inner pipe can be adjusted so that the socket spanner can be adjusted in the vertical direction; the transverse telescopic pipe is arranged at the end of the right-angle elbow pipe in the sleeved mode so that the transverse telescopic pipe and the telescopic outer pipe can be perpendicularly adjusted in the transverse direction; meanwhile, the rotating head and the transverse telescopic pipe are connected through the hinge pin, and therefore the rotating head and the transverse telescopic pipe can be rotated by 180 degrees, and therefore the socket spanner can adapt to corner work in narrow space.

Description

A kind of box spanner
Technical field
The utility model belongs to aid field, is specifically related to a kind of convenience and turns at narrow space the box spanner of operation.
Background technology
Box spanner is commonly referred to as sleeve: it is by multiple sleeves with hexagon ring or 12 jiaos of holes and be furnished with the multiple accessories such as handle, extension bar and form, and is specially adapted to twist status very narrow and small or cave in very bolt or the nut of depths.Box spanner generally all has the collet head of a set of all size and the handle of waving, extension bar, universal joint, revolve tool joint, elbow handle etc. is used for being inserted in hexagonal (hexagon)nut.The collet head of box spanner is a recessed hexagonal cylinder; For nut end or bolt end, completely lower than being connected face, and the diameter of shrinkage pool can not be used for open-end wrench or monkey wrench and double offset ring spanner,, with box spanner, is exactly just bolt part spatial limitation in addition, also can only use box spanner.
Existing box spanner technology is applicable to twist status very narrow and small or cave in very bolt or the nut of depths.For being suitable for various operating environments, kind pattern is various, but under some special operation environmental requirements, as the corner operation of narrow space, situation as shown in Figure 1, wherein A and B represent to hinder the neighbouring device parts of maintenance, and existing box spanner technology still cannot solve.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of box spanner, and reasonable in design is flexible to operation, can realize corner operation at small space.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of box spanner, comprise outer telescopic tube and flexible inner tube, outer telescopic tube is long tubular pipe fitting, one end of flexible inner tube is connected to outer telescopic tube, the other end is the corner structure with elbow bend, the end of elbow bend is socketed with the lateral extensometer draw, lateral extensometer draw one end is connected to elbow bend, the other end is provided with swivel head, described swivel head is shaft-like or cylindric, and described swivel head is that bearing pin is connected with lateral extensometer draw junction, swivel head other end installing sleeve.
The end of described outer telescopic tube is provided with two catch, and catch and outer telescopic tube at right angle setting conveniently manipulate sleeve, time saving and energy saving.
Between described outer telescopic tube and flexible inner tube, elbow bend and the lateral extensometer draw, be all connected by card bead and chute, be convenient to regulate relative size and clamp.
The utility model, owing to adopting said structure, can regulate between outer telescopic tube and flexible inner tube, realizes vertically adjustablely, and the end of elbow bend is socketed with the lateral extensometer draw, realizes vertical with outer telescopic tube laterally adjustable; Simultaneously swivel head is that bearing pin is connected with lateral extensometer draw junction, swivel head can and the lateral extensometer draw between can realize 180 degree and rotate, make the utility model can adapt to the corner operation of narrow space.
Due to the utility model due to vertically, laterally all adjustable, and between sleeve and flexible outward appearance, can form arbitrarily angled in 0-180 degree, adapt to the working environment of various complexity, reduce workload, increase work efficiency.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is the state diagram that need carry out at narrow space corner operation described in background technology.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is working state figure of the present utility model.
Detailed description of the invention
As Figure 2-3, the utility model comprises outer telescopic tube 1 and flexible inner tube 2, outer telescopic tube 1 is long tubular pipe fitting, one end of flexible inner tube 2 is connected to outer telescopic tube 1, the other end is the corner structure with elbow bend 3, the end of elbow bend 3 is socketed with the lateral extensometer draw 4, the lateral extensometer draw 4 one end are connected to elbow bend 3, the other end is provided with swivel head 5, described swivel head 5 is shaft-like or cylindric, described swivel head 5 is that bearing pin is connected with the lateral extensometer draw 4 junctions, swivel head 5 other end installing sleeves 7.
The end of described outer telescopic tube 1 is provided with two catch 6, catch 6 and outer telescopic tube 1 at right angle setting.
Between described outer telescopic tube and flexible inner tube, elbow bend and the lateral extensometer draw, all use chrome-vanadium steel manufacture and be connected by card bead, chute and groove, be convenient to regulate relative size and clamp.
Concrete, the inner side of outer telescopic tube 1 is provided with the symmetrical projection card bead of many groups, and card bead is arranged on outer tube wall inside, has part projection to be exposed at outer tube inner side, between card bead and tube wall, has shell fragment, has ensured that exposed parts is by certain decrement; Flexible inner tube 2 outsides are provided with many symmetrical chutes, and chute is for the sliding trace of fixing card bead, on chute, is symmetrical arranged 3 grooves every a segment distance, and card bead be impaction state on chute, when card bead during in groove location change play fixing position-limiting action.
The stretch mode of elbow bend 3 and the lateral extensometer draw 4 is identical with the structure of outer telescopic tube 1 and flexible inner tube 2.
When the utility model uses, first suitable sleeve is arranged on swivel head 5, adjust as required the position relationship between swivel head 5 and the lateral extensometer draw 4, make it form needed angle, then adjust the length of vertical and horizontal telescoping tube, meet job requirements, then hand is acted on to catch 6, start operation.
