Abstract
The utility model relates to a multi-purpose quick automatic spanner belongs to a hand tool, and it is by the handle, and the lock is female, activity locking piece, and the axis of rotation is constituteed. The method is characterized in that: the inner ring of the lock nut is polygonal, the handle and the movable lock block are fixedly connected or integrated with each other, and the rotation center of the handle is connected with the lock nut through a rotation shaft. The wrench has the advantages of simple, compact and reasonable structure, no ratchet wheel or screw adjusting nut, low manufacturing cost and convenient use, and can be suitable for bolts with different specifications and sizes in a certain size range.
Description
The utility model relates to a kind ofly uses fast automatic spanner more, belongs to a kind of hand-operated tools.
Disclosed spanner has two kinds usually in the prior art, and a kind of is automatic spanner, has ratchet; For a kind of be manual spanner, have the adjustable diameter and screw adjusting mother, preceding a kind of spanner high efficiency, but the nut of each size all needs corresponding a kind of spanner, so its range of application is narrow, the back is a kind of widely applicable, but inefficiency.
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of simple in structure, and wide and easy to use slightly of use face use fast automatic spanner more.
Of the present utility model many with fast automatic spanner by handle, locknut, movable lock dog, turning cylinder is formed, it is characterized in that: the locknut inner ring is a polygon, and handle and movable lock dog are mutually permanently connected or make one, and the center of rotation of handle is connected with locknut by turning cylinder.
Many fast automatic spanners of use of the present utility model, simple in structure, compact, reasonable, not only there is not ratchet but also do not have the adjustable diameter and screw adjusting mother, low cost of manufacture, easy to use, can be suitable for the bolt of the different specification size of certain size scope.
Of the present utility model use fast automatic spanner for introducing in detail more, be elaborated below in conjunction with accompanying drawing:
Fig. 1 is the plan structure schematic diagram of spanner of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view.
Referring to accompanying drawing, because it is relatively simple for structure, so only describe in conjunction with illustrating with two figure, of the present utility model many with fast automatic spanner by handle 3, locknut 1, movable lock dog 4, turning cylinder 2 is formed, it is characterized in that: locknut 1 inner ring is a polygon, and handle 3 is mutually permanently connected with movable lock dog 4 or makes one, and the center of rotation of handle 3 is connected with locknut 1 by turning cylinder 2.
Above-mentioned locknut 1 is a C shape ring body, it promptly not the closed loop circle, but about about 3/4 open loop annulus, it constitutes the closed loop circle with movable lock dog 4, another kind of scheme is that above-mentioned locknut is an O shape ring body, movable lock dog 4 is in going up or/and the bottom of ring body, better structure is to have the breach that holds movable lock dog on the ring body, can mill down one at the thickness direction of ring body and fan ring formation breach, particularly preferably be illustrated breach and open structure at the middle part of the thickness direction of described ring body, force structure is reasonable like this.
Generally be shaped on anti-slop serrations on the inner side edge of movable lock dog, prevent during use that nut is loosening therein, also make this spanner be applicable to the nut of the different size of a bigger size range.
On the movable lock dog of this automatic spanner back-moving spring 5 is housed preferably, when off working state, this back-moving spring can make the moving axis 2 that rotates between locknut 1 and the movable lock dog 4 separate convenient the use, this spring can install around in turning cylinder, also can open to be contained between movable lock dog and the locknut.
When this product used operation, as long as the locknut of annular is entangled nut or bolt, turning handle got final product then, when exerting all one's strength, linked to each other with handle or the movable lock dog of making one is tightly embraced nut or bolt, so stubborn more tight more or stubborn more loose more.
Owing to adopted above structure, spanner generally is suitable for the nut or the bolt of two to four even wider adjacent dimensions, and for example, illustrated spanner is really accomplished one-object-many-purposes applicable to nut or the bolt of M8～M20.
Claims (7)
1, a kind ofly use fast automatic spanner more, by handle, locknut, movable lock dog, turning cylinder is formed, and it is characterized in that: the locknut inner ring is a polygon, handle and movable lock dog are mutually permanently connected or make one, and the center of rotation of handle is connected with locknut by turning cylinder.
2, according to claim 1 use fast automatic spanner more, it is characterized in that above-mentioned locknut is a C shape ring body.
