Description
Technical field
The invention relates to a kind of " the buckle fixture constructions of spanner ", and espespecially one kind can be to the assembly parts card such as sleeve
Detain fixed ratchet spanner.
Background technique
The ratchet spanner being currently known mostly is equipped with a driving head and a ratchet block, driving head in the head end of wrench body
Periphery is simultaneously equipped with outer circular tooth part, and ratchet block can be engaged by the lasting pushing tow of a positioning member with the generation of outer circular tooth part, cooperates
One commutation toggle stopper ratchet block carries out blocking with the different teeth portion in two sides and outer circular tooth part periphery, will complete commutation clip
Operation.
So, there are still have following problems in practical application for known structure as described above: its using when be to drive
The polygonal holes of dynamic head provide the assembly parts such as sleeve and are inserted in, but the simple set pulls and do not have the function of positioning, therefore are using
When often need on the other hand buttress the assembly parts such as sleeve, the other hand holds spanner, is just avoided that assembly parts arbitrarily drop out again, bright in operation
Aobvious inconvenience.
Therefore the present inventor be in view of this, be think and creation idea, designed then with the experience of many years, visited in many ways
Sampling test is begged for and studied, and repeatedly amendment improvement, is releasing the present invention.
Summary of the invention
The technical issues of to be solved point:
Known ratchet spanner using when be to provide the assembly parts such as sleeve with the polygonal holes of driving head to be inserted in, but this is simple
Set, which is pulled, does not have the function of positioning simultaneously, this is to be solved the technical issues of point.
The technical characterstic solved the problems, such as:
