Description
Technical field
The utility model relates to a kind of instrument, is specifically related to a kind of spanner.
Background technology
Spanner is a kind ofly to be used for fastening or to unscrew the instrument of bolt, nut or similar workpiece; Usually be shaped on the trepanning of fixed dimension and shape (like pentagon, hexagon, octagon etc.) in the one or both ends of its shank, in order to the nut or the bolt of twisting this size and dimension.But the workmen does not often know the size and dimension of nut, bolt in advance when carrying out operation, and this just need carry very inconvenient with the spanner of going up various sizes and shape trepanning.In addition, this spanner is when acting on bolt or the nut that is positioned at narrow and small or depression depths, space, and relatively difficulty operates also.
The utility model content
The utility model technical problem to be solved is the deficiency to above prior art, provides a kind of detachable, rotatable, easy to carry single head a spanner alive.
For addressing the above problem; The utility model provides a kind of single head a spanner alive; Comprise that an end is provided with the wrench body of ten jiaos of plum blossom trepannings, the other end of said wrench body is hinged with through alignment pin can be around the driving end of alignment pin rotation, and said alignment pin is connected with wrench body is removable.
Said driving end is the different driving ends of a plurality of cover hole dimensions.
The trepanning of said driving end is shaped as pentagon or hexagon or octagon or decagon or dodecagon.
Said driving end can rotate in 180 ° of scopes around alignment pin.
After adopting above structure; The utility model compared with prior art; Have the following advantages: an end of the wrench body of the utility model single head spanner alive is established ten jiaos of plum blossom trepannings, and the other end is hinged with driving end through alignment pin, and alignment pin is connected with wrench body is removable.When needing the driving end of specific dimensions and given shape trepanning; Alignment pin capable of using is pulled down unwanted driving end with the removable structure that is connected of wrench body, will need the driving end of size and dimension trepanning to be hinged on wrench body with alignment pin more then and just can.So the workmen is when going out to construct; Only need carry this single head spanner alive and just can satisfy the construction needs; Just can operate bolt, nut or the similar workpiece of multiple size, multiple shape trepanning; And driving end all diminishes aspect volume and weight for spanner greatly, gives to carry to bring convenience.In addition; Wrench body is hinged through alignment pin and driving end; Driving end can rotate around alignment pin; This structure can not only be operated this single head spanner of living to bolt, nut or the similar workpiece of general position, also is applicable to fastening or unscrews bolt or the nut that is positioned at narrow and small or depression depths, space.
Description of drawings
Shown in Figure 1 is the structural representation of a kind of single head of the utility model spanner alive;
Shown in Figure 2 is the A-A cross-sectional view of Fig. 1.
Wherein: 1, wrench body; 2, alignment pin; 3, driving end.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to detail.
Like Fig. 1, shown in Figure 2; A kind of single head of the utility model spanner alive comprises that an end is provided with the wrench body 1 of ten jiaos of plum blossom trepannings; The other end of wrench body 1 is hinged with through alignment pin 2 can be around the driving end 3 of alignment pin 2 rotations, said alignment pin 2 and 1 removable connection of wrench body.Wrench body 1 is the spanner of prior art, and promptly shank one end of spanner is shaped on fixed dimension, the cross section is the trepanning of ten jiaos of plum blossoms.
Said driving end 3 is the different driving ends of a plurality of cover hole dimensions.The trepanning of said driving end 3 is shaped as pentagon or hexagon or octagon or decagon or dodecagon.More than the shape of these trepannings be with the outer cross sectional shape coupling of bolt commonly used in the market or nut, certainly, the cover hole shape of driving end 3 also can for other shapes of need operation workpiece coupling.The trepanning of the driving end 3 that present embodiment adopts is shaped as pentagon, certainly, also can be hexagon or octagon or decagon or dodecagon, or meet other shapes of construction needs.Here the situation of the size and shape of the trepanning of driving end 3 comprises three kinds: 1. the cover hole dimension of driving end 3 is different, shape is identical; 2. the trepanning of driving end 3 is measure-alike, shape is different; 3. the cover hole dimension of driving end 3 is different, shape is also different.
Said driving end 3 can rotate in 180 ° of scopes around alignment pin 2, also can operate the bolt or the nut of narrow and small place, space or depression depths.The other end of wrench body 1 engages with the projecting block of driving end 3 bottoms and is provided with preset holes radially, and alignment pin 2 can be screw, is combined on the preset holes that is provided with internal thread, and alignment pin 2 also can be taper pin, tightly plugs together in preset holes.
Above embodiment be to the explanation of the utility model with explain that further rather than to the restriction of the utility model, any modification of in the interest field of the utility model, being done all falls into the protection domain of the utility model.
