Abstract

The utility model discloses an universal socket wrench, including the casing, the casing upper end is equipped with the power interface, and power interface and power device looks adaptation, casing lower extreme are equipped with the hexagon the core of the card, and the core of the card endotheca is equipped with at least two -layer sleeve, and sleeve from interior to exterior length reduces gradually, and there is L type turn -ups every telescopic upper end, and every layer of sleeve top all receives the decurrent pressure of spring, and under the pressure of every spring, the telescopic L type turn -ups of inlayer is taken on the telescopic turn -ups of skin, and the telescopic lower extreme of each layer keeps the parallel and level. The core of the card is the hexagon, with sleeve outline looks adaptation. Utilize an omnipotent sleeve to accompany and to integrate 4 5 well sleeve reaches multi -purpose function, reduces the user and need carry the box spanner of multiple specification, for the user provides convenience, has improved work efficiency.

Description

Universal socket wrench

Technical field

This utility model relates to installation tool technical field.

Background technology

Box spanner is by multiple band hexagon rings or the sleeve of 12 corner apertures and to be furnished with the multiple accessories group such as handle, extension bar Become, be particularly well-suited to twist that position is the narrowest and small or the bolt of depression very deep or a kind of instrument of nut.At the construction field (site), spiral shell Pig gauge lattice are more, will the spanner of band all size, more inconvenience when workman constructs.Inventor designs a kind of omnipotent sleeve barrel spanner Hands, as long as in the case of being not required to use high pulling torque bolt, can be at the nut adapting to all size.

Summary of the invention

Technical problem solved by the invention is to provide a kind of box spanner being applicable to all size nut.

The technical solution used in the present invention is a kind of universal socket wrench, and including housing, housing upper end is provided with power interface, Power interface is suitable with power set, and housing lower end is provided with hexagon the core of the card, is set with at least two-layer sleeve, sleeve in the core of the card Length is gradually reduced from the inside to the outside, and there is L-type flange the upper end of each sleeve, all by the pressure that a spring is downward above every layer of sleeve Power, under the pressure of each spring, the L-type flange of inner layer sleeve rides on the flange of outer layer sleeve, and the lower end of each layer sleeve is protected Maintain an equal level neat.

The core of the card is hexagon, suitable with sleeve outline.

The invention has the beneficial effects as follows that a Universal sleeves, with integrating 4-5 middle sleeve, reaches multi-purpose function, minimizing makes User needs to carry the box spanner of plurality of specifications, provides convenient for user, improves work efficiency.

Accompanying drawing explanation

Fig. 1 is this utility model structural representation.

Fig. 2 is the sectional view along A-A direction.

Fig. 3 is the sectional view along B-B direction.

Figure is labeled as: 1-spring, 2-stop nut, 3-the core of the card, 4-wrench adapter, 5-power interface.

Detailed description of the invention

The invention will be further described below in conjunction with the accompanying drawings.

As it is shown in figure 1, universal socket wrench of the present utility model, in the core of the card 3 of housing, devise multi-level sleeve, The bolt of the corresponding a kind of specification of each sublevel, every layer of sleeve can be with independent telescope, and every layer of sleeve has individual approximate dimensions the same The spring 1 of hexagonal configuration links, and spring 1 upper end is suppressed by the dividing plate on housing, and lower end applies downward power to the flange of sleeve, Realizing every layer of downward reset of sleeve, the actual l-shaped in upper end of every layer of sleeve, the flange of L-type rides over turning over of outer layer sleeve successively Bian Shang, its effect is to limit every layer of sleeve to reset at same position.The core of the card 3 is in hexagon, with hexagonal sleeve configuration phase Adaptive, it is simple to band moving sleeve rotates.

As in figure 2 it is shown, the housing of box spanner the most just designs a power interface, for box spanner and electric wrench Or manual wrench connects, and refers to the power interface schematic diagram suitable with adapting rod of Fig. 3

In view of practical application, at most can only be suitable for twisting the hex nut of 4-5 kind different size, be mainly in view of this Design dexterity.

Actually used explanation: the specification of such as box spanner is the general-purpose box spanner of M4, M6, M8, M10, M12 specification, The Hexagonal jacket of innermost layer is nut or the bolt of m4, sleeve is directed at nut or the nut of m4, pins downwards set Cylinder, the inner ring of innermost m4 layer is just m4 Bolt sizes, and such innermost layer sleeve is nested with bolt, twists box spanner Both left-right rotation can have been completed.If you need to twist the bolt of m6, bolt or nut are directed at second layer sleeve layers, firmly to Under pin sleeve, one layer of sleeve of the one layer of i.e. m4 of sleeve in the inside will by top up, after the sleeve of m4 moves up, after Second layer sleeve inner ring size is just the sleeve of the big stove bolt of m6, so blocks m6 nut, can twist left and right, class successively Push away.M8, m10, m12, bolt twisting actions can be completed.

This kind of design structure of this utility model can integrate 4-5 middle sleeve, thus can reach multi-purpose function, reduce user Need to carry the box spanner of plurality of specifications, provide convenient for user, improve work efficiency.

Claims

1. universal socket wrench, it is characterised in that: including that housing, housing upper end are provided with power interface, power interface fills with power Putting suitable, housing lower end is provided with hexagon the core of the card, is set with at least two-layer sleeve in the core of the card, and sleeve length from the inside to the outside is gradually Reducing, there is L-type flange the upper end of each sleeve, all by the pressure that a spring is downward above every layer of sleeve, at each spring Under pressure, the L-type flange of inner layer sleeve rides on the flange of outer layer sleeve, and the lower end of each layer sleeve keeps concordant.

2. universal socket wrench as claimed in claim 1, it is characterised in that: the core of the card is hexagon, fits mutually with sleeve outline Join.
