Abstract
The utility model belongs to a mechanical tool, and relates to a fast opened wrench which comprises a single-combined fast opened wrench and a multi-combined fast opened wrench, wherein a zigzag step with a 60 DEG angle is arranged on the upper jaw surface or the lower jaw surface of the single-combined fast opened wrench, and one end of the zigzag step is connected with platforms at the front end of the upper jaw surface and the lower jaw surface; the other end of the zigzag step is connected to the circular arc part of the wrench, and the zigzag step is matched with the square corner of a screw. A plurality of zigzag steps with 60 DEG angles are arranged on the upper jaw surface or the lower jaw surface of the multi-combined fast opened wrench, and the zigzag steps are matched with the square corners of a plurality of screws with different specifications. The utility model has the advantages of tightness, high disassembling speed, high work efficiency, simple structure, low cost and high reliability.
Description
The utility model belongs to machine tool, relates to a kind of fast opening spanner.
Use at present tight or unload instrument that screw uses nothing more than being two kinds, be common open-end wrench, monkey wrench, common open spanner is hand-tight or when unloading screw, the opening of spanner is put into the side of screw, spanner is pulled 60 degree, from screw side spanner is taken out, spanner is got back to original position, tight like this or unload again busy soon not yet, waste many times, work efficiency is low, and it is narrow to add the common open-end wrench scope of application, has only two kind 14,17 specification.Monkey wrench is along with the specification difference of screw will be adjusted opening size at any time.
The purpose of this utility model is to address the above problem, and a kind of fast opening spanner with plurality of specifications is provided.
The purpose of this utility model is achieved in that a kind of fast opening spanner, it includes single group fast opening spanner, many combination fast opening spanners, the serration type step of angle 60 degree wherein is set on the upper shed face of the single group of a. fast opening spanner or the under shed face, the one end is connected going up or the lower front end platform of fast opening spanner, the other end is connected the circular arc portion of fast opening spanner, pass the rivet of symmetry at fast opening spanner both ends open front-back, serration type step and screw corner coincide: b. makes up the serration type step that a plurality of angle 60 degree are set on going up of fast opening spanner or the under shed face more, the one end is connected going up or the lower front end platform of fast opening spanner, its last group serration type step one end is connected the circular arc portion of fast opening spanner, and a plurality of angle 60 degree serration type steps a plurality of screw corners different with specification coincide.
The utility model has the advantages that (1) because fast opening spanner special geometric form, this side that spanner can break away from screw automatically slides in the next one side, screw can not reverse, and then positive direction is pulled spanner, spanner can produce torsion to screw again, screw rotates, spanner does not leave the continuous both forward and reverse directions of screw and pulls spanner like this, screw will rotate, so just can be fast tight screw, as when unloading screw, as long as it is just passable that spanner is turned out, quick-moving 3 times of fast opening spanners than common open spanner.(2) common open-end wrench has the combination (14,17) of two kinds of specifications, and the fast opening spanner can have the combination of five kinds of specifications, it is identical with the scope of application of monkey wrench that it is suitable for GB-51-76 nut all specifications below 22, and do not need the adjustment opening size resemble the monkey wrench; (3) simple in structure, manufacturing process is simple, and cost is low, work efficiency is high.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the utility model list group fast opening spanner structure schematic diagram
Fig. 2 is the utility model list group fast opening spanner A-A cutaway view
Fig. 3 makes up fast opening spanner structure schematic diagram for the utility model more
Fig. 4 is the structural representation of shooting property of the utility model fast opening spanner catch
Fig. 5 is the structural representation of the utility model elastic block piece
Below in conjunction with accompanying drawing the utility model is further described, as Fig. 1, shown in Figure 3, it includes single group fast opening spanner the utility model, many combination fast opening spanners, the serration type step 3 of angle 60 degree is set on the upper shed face 1 of a. single group fast opening spanner or the under shed face 2, the one end is connected last 4 or lower front end platform 5 of fast opening spanner, the other end is connected the circular arc portion 6 of fast opening spanner, as shown in Figure 2, pass the rivet 7 of symmetry at fast opening spanner both ends open front-back, serration type step 3a and screw corner coincide; The serration type step 3a of a plurality of angle 60 degree is set on the last 1a of b. many combination fast opening spanners or the under shed face 2a, the one end is connected the last 4a or the lower front end platform 5a of fast opening spanner, its last group serration type step 3a one end is connected the circular arc portion 6a of fast opening spanner, and a plurality of angle 60 degree serration type steps a plurality of screw corners different with specification coincide.As Fig. 4, shown in Figure 5, on fast opening spanner reverse side opening surface, coupling type elastic block piece 8 is set, its two ends, hook outside groove rivet 7 positioning and fixing.The fast opening spanner that elastic block piece can be installed can prevent that spanner from sliding up and down, and holding screw is faster, has improved work efficiency.
