Detailed Description

The following description of the preferred embodiments of the present invention will be provided with reference to the accompanying drawings, so that the advantages and features of the present invention can be easily understood by those skilled in the art, and the scope of the present invention can be clearly and clearly defined.

The embodiment of the utility model provides an include:

example 1

As shown in fig. 1, a double-connection wrench 1 comprises a first handle 11 and a second handle 12, wherein one end of the first handle 11 is vertically connected with one end of the second handle 12, the other end of the first handle 11 and the other end of the second handle 12 are both provided with an inner hexagonal sleeve 13, and the inner hexagonal sleeve 13 is a standard component. The first handle 11 and the second handle 12 are an integral connecting structure, and 2 hexagon socket caps 13 are fixedly connected to the ends of the first handle 11 and the second handle 12 in a hot heading forming mode. The double-connection-head wheel wrench 1 is simple in overall structure and practical.

Specifically, the first handle 11 is a short arm, and the second handle 12 is a long arm, that is, the length of the first handle 11 is less than that of the second handle 12, and the length of the first handle 11 is 1/3 of the length of the second handle 12.

Through the length of the first handle 11 and the second handle 12 and the design that the first handle 11 and the second handle 12 are provided with the inner hexagonal sleeves 13, the double-connection wheel wrench 1 achieves the following effects during operation: when the vehicle screw nut needs to be disassembled or the wheel nut needs to be further fastened, the force arm is increased by utilizing the characteristic of the long arm section and the arm length of the inner hexagonal sleeve 13 at the tail end of the first handle 11 to be matched with the wheel nut 2, so that the aim of saving labor is fulfilled;

when the wheel nut is just mounted or is unscrewed, and the force required by rotation is small, the inner hexagonal sleeve 13 at the tail end of the second handle 12 is matched with the wheel nut 2, and the wheel nut is quickly screwed or dismounted by utilizing the characteristic of small rotation radius of the short arm section, so that the operation radius of the wheel wrench can be reduced, the operation is convenient for a user, the operation efficiency is improved, and the time is saved, as shown in fig. 2.

Example 2

As shown in fig. 3, a combination wrench, includes above-mentioned double connection head wheel spanner 1 and adapter 3, double connection head wheel spanner 1's structure is with embodiment 1, adapter 3 is shaft-like structure, and its one end is outer hexagonal joint 31, can with double connection head wheel spanner 1's interior hexagonal head plug-in cooperation, and its other end has interior hexagonal cover 32, also is the standard component, can cooperate with wheel nut 2 or other instruments. The outer hexagonal connector 31 of the adapter 3 is connected with the inner hexagonal sleeve 13 on the second handle 12 of the double-connection wheel wrench 1 in a plug-pull manner to form a detachable combined wrench.

The use method of the combined wrench comprises the following steps:

when the car nut or further fastening wheel nut were dismantled to needs, utilize the terminal interior hexagonal cover 13 of first handle 11 and the cooperation of wheel nut 2, the 13 plug-in connections of interior hexagonal cover on adapter 3 and the second handle 12, adapter 3 plays the effect of extension bar, can effectively increase the arm of force to play laborsaving purpose, as shown in fig. 4.

When the wheel nut is installed or loosened, the force required by rotation is small, the adapter 3 can be detached, the inner hexagonal sleeve 13 at the tail end of the second handle 12 is matched with the wheel nut 2, the adapter can not be detached, the inner hexagonal sleeve 32 of the adapter 3 is directly matched with the wheel nut 2, the wheel nut can be screwed or detached quickly, the operation radius of the wheel wrench can be reduced, the operation of a user is facilitated, the operation efficiency is improved, and the time is saved.
