In another case of the present embodiment, the first wrench 21 and the second wrench head 22 can be a box wrench head, and the third wrench head can be a box wrench head, a movable wrench head, a socket wrench head, or other types of wrench heads, so that the composite wrench of the present embodiment has a variety of uses.

In one embodiment, the compound wrench further comprises a spacer plate positioned between the first opening 211 and the second opening 221 to separate the first opening 211 and the second opening 221. The spacer separates the first opening 211 and the second opening 221, and when the spacer abuts against the top of the screw to be tightened by a worker who performs a tightening operation using the first wrench head 21 or the second wrench head 22, the tightened position on the outer wall of the screw is engaged with the corresponding opening, and the spacer performs a positioning function, so that the convenience of use of the compound wrench of the present embodiment is improved, the time required for the worker to perform alignment is reduced, and the work efficiency is further improved.

In one embodiment, the first wrench head 21, the second wrench head 22 and the third wrench head 31 are welded to the grip 1, and the first wrench head 21 and the second wrench head 22 are connected by welding. First spanner head 21 and second spanner head 22 pass through welded connection, do not have the clearance between the two, no matter be when first spanner head 21 carries out the screwing up operation or when second spanner head 22 carries out the screwing up operation, another spanner head of not operation also can bear torsion together, consequently reduced the work damage of spanner head, the life of part has been improved, the cost is reduced to a certain extent, make the instrument cost of vehicle chassis screwing up the station reduce to 10 yuan monthly.

In an embodiment, the grip 1 includes a first connecting section 11, a holding section 12, and a second connecting section 13 connected in sequence, where an end of the first connecting section 11 away from the holding section 12 is connected to the first tightening structure 2, and an end of the second connecting section 13 away from the holding section 12 is connected to the second tightening structure 3.

In this embodiment, the first connection section 11 is integrated with the first tightening structure 2, and the second connection section 13 is integrated with the second tightening structure 3. In-process of screwing up the operation is carried out at compound spanner, first structure 2 of screwing up, the junction of second structure 3 and the handle of gripping 1 is weakest, and the design of this embodiment has strengthened first structure 2 of screwing up, the intensity of second structure 3 and the junction of the handle of gripping 1 of screwing up, compound spanner's in this embodiment life has not only been prolonged, and still can reduce first structure 2 of screwing up, the second structure of screwing up 3 and the probability of breaking takes place in the junction of the handle of gripping 1, reduce the safety risk in the operation process, the safety in utilization performance of the compound spanner of this embodiment has been strengthened to a certain extent.

Furthermore, a holding ring 15 is arranged on the holding section 12, and the holding ring 15 is formed by protruding outwards from the outer wall of the holding section 12. As shown in fig. 1, the grip ring 15 protrudes from the outer surface of the grip 1, in the prior art, the grip 1 of the wrench is generally small, which affects the use feeling of the operator, and the design of the grip ring 15 in this embodiment not only meets the requirement of the hand feeling of the operator, but also does not need to increase the thickness of the entire grip 1, thereby saving the material cost.

In the process of using the composite wrench of the present embodiment, the operator grasps the grip ring 15 to control the entire composite wrench, rotates the grip ring 15 to tighten the screw when the wrench head is engaged with the outer wall of the screw, and turns the grip ring 15 to change the wrench head when the wrench head is not of the proper size. Simple structure and convenient use.

Furthermore, the outer wall of the holding ring 15 is provided with anti-slip threads, so that when an operator holds the holding ring 15, the anti-slip threads can increase friction force, reduce the possibility that the composite wrench falls off from the hand of the operator, prevent safety accidents, and further improve the use safety performance of the composite wrench of the embodiment. In another embodiment, the outer wall of the grip ring 15 is provided with a grip groove, which is a profile design structure that the operator can match with fingers when gripping the grip ring 15, so as to improve the use feeling and to grip the grip ring 15 more firmly.

In one embodiment, the gripping section 12 and the gripping ring 15 are made of stainless steel. The grip ring 15 and the grip section 12 are the most contacted parts of the composite wrench by the operator, so that the two parts are most easily corroded by salt and sweat on hands, and the corrosion degree can be reduced and the rusting can be prevented by using the stainless steel material. The remaining parts of the composite wrench except the grip 12 and the grip ring 15 are made of alloy steel having a density greater than that of stainless steel, so that the quality of the entire composite wrench can be reduced by making the grip 12 and the grip ring 15 of stainless steel, the burden on the operator can be reduced, and the efficiency of the operator can be improved to a certain extent.

In an embodiment, compound spanner is integrated into one piece finished piece, has improved compound spanner's bulk rigidity, has improved compound spanner and has resisted the ability of warping, has promoted the life of compound spanner of this embodiment, has reduced the required cost of changing compound spanner.

In one embodiment, the grip 1 is provided with a weight-reducing slot 14 therethrough, and the weight-reducing slot 14 is arranged along the length direction of the grip 1. As shown in fig. 1, in this embodiment, the grip 1 is provided with lightening slots 14, the lightening slots 14 are narrow, and the grip ring 15 is located outside the lightening slots 14. In another case of this embodiment, the grip ring 15 is not provided on the grip 1, and the weight-reducing grooves 14 are longer in length and reduce more weight. Both of the above two situations are to adjust the quality of the composite wrench, so that the quality of the composite wrench does not affect the operation of the operator due to too heavy weight, and has a certain quality to assist the operation of the operator. Thus, the design of the lightening slots 14 ensures the rational mass of the compound wrench of the present embodiment.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the technical solutions of the present invention, which are made by using the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
