Detailed Description
the utility model is shown in figures 1-4 and comprises a spanner body 1, a connecting body 2 and a plurality of spanner columns 3;
A containing cavity matched with the nut or bolt 4 is formed among the pull columns 3 and is uniformly and fixedly arranged on the connecting body 2;
the inner side surface of the connecting body 2 is matched with a nut or a bolt 4;
A pulling hole is formed in the pulling body 1, and a plurality of arc-shaped grooves 11 matched with the pulling columns 3 are formed in the pulling hole;
The number of the arc-shaped grooves 11 is equal to that of the pull columns 3, and the arc-shaped grooves correspond to the pull columns one by one.
The scheme adopts six pull columns 3, and is fixed on a connecting body 2 made of plastic materials through an injection molding method, a plurality of arc-shaped grooves 11 are processed on the inner side of a wrench head, a combination body formed by the connecting body 2 and the pull columns 3 is placed in a pull hole, a containing cavity matched with a nut or a bolt 4 is formed between the pull columns 3, the nut is placed in the wrench through slight stress applied by elastic deformation of the connecting body 2, and the nut is clamped by the plate columns through the elasticity of the connecting body 2.
As shown in fig. 2, when the bolt 4 is wrenched, the angle of the bolt 4 is not damaged; meanwhile, if the bolt 4 is damaged when meeting the angle of the bolt 4, the bolt 4 can be used as shown in figure 4;
when the bolt 4 is screwed by a traditional double offset ring spanner, the double offset ring angle of the spanner contacts with the bolt 4, and the hardness of the spanner is higher than that of the bolt 4, so that the angle of the bolt 4 is easily damaged when the bolt 4 is screwed. When the wrench is used, the working surface of the wrench column 33 is in contact with the middle part of the surface of the bolt 4, so that the corner of the bolt 4 is not damaged, as shown in fig. 3;
similarly, if the bolt 4 with damaged bolt 4 corner is encountered, the operation cannot be performed by using the traditional ring spanner, and the operation can be continued by using the spanner, as shown in fig. 4.
The two ends of the pulling column 3 are respectively provided with a leading-in edge 31. The convenient leading-in appearance intracavity of bolt 4 or nut of being convenient for improves the availability factor of spanner.
the connecting body 2 is an elastic body and is made of plastics.
The number of the pulling columns 3 is six. The six wrench columns 3 are made of high-strength alloy steel respectively, so that the service life of the wrench is prolonged. Because the high-strength alloy steel is expensive, the processing cost is high, the whole wrench cannot be used, the wrench column 3 of the wrench is small in size, the cost of using the high-strength alloy steel is not greatly increased, and the manufacturing cost of the wrench is reduced.
the number of the arc-shaped grooves 11 is six.
The side of the pulling columns 3 facing the nuts or bolts 4 is a plane. Facilitating the stable clamping of the bolt 4 or nut. Further optimize, be equipped with a plurality of recesses on the plane, be equipped with the rubber arch in the recess, the rubber arch slightly is followed the recess and is protruded, improves the stability of centre gripping nut. The nut can be clamped to be sent into the bolt 4 to work or can be taken away from a working space along with the wrench after the nut is loosened, and the nut is suitable for the situation that the space is narrow.
