Abstract

The utility model relates to a convenient wrench with a magnetic connection wrench head, which comprises a wrench handle and a wrench head, wherein the wrench head is inserted on the wrench handle, and an elastic clamping piece is arranged between the wrench handle and the wrench head. The utility model has the advantages that the spanner and the sub-spanner with different specifications can be conveniently replaced by adopting one spanner handle, the screw nuts with different specifications can be pulled and screwed, the volume is small during storage, the weight is light, and the consumption of raw materials is less.

Description

Magnetic connects the convenient wrench of spanner

The utility model belongs to a kind of hand-operated tools, the particularly a kind of convenient wrench that can change the different size spanner.

Existing manual wrench all is that spanner and trigger piece are one, therefore an end has the screw-nut that can only pull a specification of spanner, and there is the screw-nut of also pulling two specifications at most of spanner at two ends, and the spanner of the more complete complete sale of specification is all about ten, big, the Heavy Weight of volume during keeping, and raw material expend many.

The purpose of this utility model provides the convenient wrench that a kind of magnetic connects spanner, adopts a trigger piece can be convenient for changing the spanner and the sub-spanner of different size, screw-nut that can the twisting different size, and volume is little, in light weight in the time of certainly, and it is few to expend raw material.

The purpose of this utility model is achieved in that it comprises trigger piece and spanner, and the spanner of pegging graft on the trigger piece is equipped with the elasticity Fastener between the two, and its technical characterictic is: spanner pull a mouthful interior magnetic connexon spanner.

The utility model has the advantages that: adopt a trigger piece, can be convenient for changing the spanner and the sub-spanner of different size, the screw-nut of energy twisting different size, volume is little, in light weight during keeping, and it is few to expend raw material.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 7 is the utility model embodiment 4 structural representations.

Fig. 8 is the sub-spanner schematic diagram of band slot.

See Fig. 1,2, embodiment 1 structure: the trigger piece 1 end grafting spanner 2 of crank shape, assembling makes the card pearl 4 and the spring 3 of spanner 2 location on the trigger piece 1.Can the inside and outside polygonal sub-spanner 5a of plug-in mounting band in interior polygonal (Nei Sijiao, the interior hexagonal etc.) of spanner 2 are pulled mouthful, but the plug-in mounting spanner 5a of small dimension more also in the sub-spanner 5a.Spanner 2 and sub-spanner 5a have magnetic, perhaps both one of have magnetic.When being used in combination, spanner 2 and sub-spanner 5a be pulled together.The utlity model has a trigger piece 1, dispose two above spanners 2, the screw-nut of pulling a specification of mouth energy twisting of each spanner 2,1 to 3 sub-spanner that each spanner 2 configuration is pegged graft, the screw-nut of a specification of each sub-spanner energy twisting.See Fig. 3, sub-spanner 5b is Wai Sijiao, outer-hexagonal, outer anistree solid construction, to adapt to the needs that turn interior polygonal (Nei Sijiao, interior hexagonal, interior anise etc.) bolt.

See Fig. 4, embodiment 2 structures; Pull shape trigger piece 1 two ends grafting spanner 2, the mouth of pulling that band is pulled the spanner 2 of mouth is through-hole structure, the sub-spanner 5a of the spanner grafting hollow-core construction of this structure, and when the twisting nut, bolt end can pass spanner; For polygonal (Nei Sijiao, interior hexagonal, interior anise) bolt in the sub-spanner 5b energy of the solid construction twisting.Spanner 2 can be taked jump ring 6 location draw bails with trigger piece 1, also can adopt the location draw bail of embodiment 1 described card pearl 4 and spring 3.

See Fig. 5, embodiment 3 structures: trigger piece 1 is a T font structure, and the draw bail of spanner 2 and trigger piece 1 is with embodiment 1.See Fig. 6, the draw bail of spanner 2 and trigger piece 1 can be as follows: trigger piece 1 has jack, and spanner 2 is plugged in the jack, location structure can adopt jump ring or card pearl any.

See Fig. 7, embodiment 4 structures: an end of trigger piece 1 has jack, and spanner 2 is inserted in the jack, by locator card pearl and spring location, spanner 2 pull mouthful sub-spanner of interior plug-in mounting, sub-spanner has two kinds of structures, a kind of is the sub-spanner 5c that slot is arranged as shown in Figure 8, prevents play behind the plug-in mounting; The hollow sub-spanner 5a that also has a kind of embodiment of being 1.

The magnetic draw bail of spanner and sub-spanner is with embodiment 1 among the embodiment 2-4.

Claims

1, a kind of magnetic connects the convenient wrench of spanner, comprises trigger piece and spanner, and the spanner of pegging graft on the trigger piece is equipped with the elasticity Fastener between the two, it is characterized in that: spanner pull a mouthful interior magnetic connexon spanner.
