Abstract

The utility model relates to a multifunctional spanner which is composed of a spanner and two sets of accessories. The accessory 1 is a set of serial inner hexagon spanner heads with different size specifications, and the accessory 2 is a set of serial screwdriver bars with different size specifications. One end of the spanner is provided with a plurality of pentagon grooves with different sizes in a circumferential direction to be used as outer hexagon spanner heads, and the other end is provided with a plurality of trilateral grooves with different sizes in a circumferential direction to be used as outer square spanner heads. Each middle part is provided with a shaped orifice which can be matched with the inner hexagon spanner head of the accessory 1. Both ends of the spanner are connected into a whole by an S-shaped plate. The middle part of the S-shaped plate is provided with two rectangular shaped orifices which can be matched with the screwdriver bars of the accessory 2 to be used as screwdrivers. The utility model has the advantages of multifunction, wide use, easy production and low price.

Description

Multifunctional spanner

The utility model belongs to be tightened or general hand tools during securing member such as demounting bolt, nut, screw, wood screw.

Similar tools commonly used at present has single, double head (staying) spanner, monkey wrench, double offset ring spanner, box spanner and various screwdrivers etc.These instruments all purposes are single, cut both ways.Tighter as fork spanner and bolt (mother) interlock, be difficult for skidding, but it is like that flexible adjustable to be not so good as monkey wrench.And the gap that monkey wrench is regulated between parts often makes spanner and workpiece interlock not firm, particularly when need turn with high pulling torque, easily skids, and is dangerous, finally even can't use.In addition, the fork spanner specification is various.The complex structure of other types, the cost height causes a lot of wastes and difficulty for manufacturing and use.

For solving the above-mentioned shortcoming of spanner class instrument, the utility model integrates all regular size spanners, in the hope of reaching a thing at hand, multi-functional economical and practical purpose through screening.

One end of the utility model spanner circumferentially has several pentagon type grooves that varies in size, and the middle part of this transverse plane has a hexagon type hole; The other end of spanner circumferentially has several triangle type grooves that varies in size, and has a quadrangle type hole in the middle part of this transverse plane.The spanner two ends are by the S shape platysome spanner integral body that is formed by connecting.Have two rectangular type holes in the middle part of S shape platysome.S shape platysome and junction, spanner two ends respectively have a hook-type type groove.

Concrete structure of the present utility model is provided by following example and accompanying drawing.

Fig. 1 is an embodiment of the present utility model;

Fig. 2 is the schematic diagram of hexagonal wrench in one group of series that varies in size of the present utility model; (annex one)

Fig. 3 is one group of serial screwdriver rod schematic diagram that varies in size of the present utility model.(annex two)

Below in conjunction with description of drawings concrete structure of the present utility model and purposes.

Hexagonal wrench (Fig. 2), two groups of annexes of screwdriver rod (Fig. 3) were formed in the utility model was reached by spanner (Fig. 1).(Fig. 2) a kind of interior hexagonal wrench only is shown, in fact this group annex is the interior hexagonal wrench of series commonly used that size specification has nothing in common with each other; (Fig. 3) two kinds of screwdriver rods only are shown, in fact this group annex is different serial yi word pattern screwdriver rod and the cross screwdriver rod commonly used of size specification.

Spanner left end 1 plane circumferentially have a pentagon type groove that several vary in size, can be used as serial outer-hexagonal wrench commonly used; Spanner right-hand member 2 planes circumferentially have a triangle type groove that several vary in size, can be used as the outer cubic wrench of series commonly used.

The type hole 2 of the middle part of 1 transverse plane both can be used as the outer-hexagonal wrench, the socket of hexagonal wrench in can be used as again.When an end 8 insertions 2 holes of the interior hexagonal wrench shown in (Fig. 2), hexagonal wrench in promptly can be used as; The type hole 6 of the middle part of 2 transverse planes both can be used as outer cubic wrench, the socket of hexagonal wrench in also can be used as.

Shown in (Fig. 1), 3 and 4 is bicycle hook-type wrench.S shape platysome between 3 and 4 is the handle of multifunctional wrench.This handle and 3,4 forms two bicycle hook spanners.Be used for loading and unloading the securing members such as nut on the bicycle.Handle forms serial outer-hexagonal spanner and inner hexagon spanner with 1 end; Handle forms outer cubic spanner of series and inner hexagon spanner with 2 ends.Pinch bar also can be used as the handle of screwdriver.

The utility model compared with prior art, its remarkable advantage is: collect inside and outside hexagonal, the multiple regular size spanner such as outer four directions and screwdriver be in one, is simple and easy to do, and both can save lot of materials, reduce cost, and be again easy to use. It is the desirable general hand tools of common mechanical engineering, household electrical appliance, traffic apparatus.

Claims
