Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description.

The specific implementation manner of the utility model is as follows: as shown in fig. 1-6, a multipurpose tightening tool comprises a torque wrench 1, a wrench socket 2 is detachably disposed on the torque wrench 1, and an open wrench 3 perpendicular to the axial line of the wrench socket 2 is disposed on one side of the wrench socket 2. In the multipurpose screwing tool, a section of open-ended wrench 3 is welded on a wrench sleeve 2, so that two flywheel housing fixing bolts 7 can be screwed under the condition that only one tool is used during assembling of the flywheel housing, other tools do not need to be replaced, the production efficiency is improved, the labor load of workers is reduced, and the consistency of the torque used for screwing the flywheel housing fixing bolts 7 is ensured; the tool has the characteristics of low cost, reliable technology, convenient and quick use and simple operation.

In this embodiment, the open-end wrench 3 is fixed on the wrench socket 2 at an end close to the torque wrench 1, that is, the plane where the force point of the wrench socket 2 when receiving the torque force is coplanar with the plane where the force point of the open-end wrench 3 when receiving the torque force, so as to avoid the torque error caused by the difference of the force directions of the operators.

In the present embodiment, the open end wrench 3 includes a connecting rod 31 extending outward in the radial direction of the wrench socket 2 and a bayonet 32 provided at an end of the connecting rod 31. The open end wrench 3 is perpendicular to the wrench socket 2, so that the central axis of the bayonet 32 is parallel to the central axis of the wrench socket 2.

In this embodiment, the torque wrench 1 includes a handle 11 and a connecting disc 12 disposed at one end of the handle 11, the wrench socket 2 is installed at the center of the connecting disc 12, the center line of the handle 11 is collinear with the center of the connecting disc 12, and the connecting rod 31 is parallel to the center line of the handle 11.

In this embodiment, the connecting rod 31 is provided with weld seams on the top and bottom surfaces thereof for connecting to the outer wall of the wrench socket 2. The welding seam is positioned on the end of the wrench socket 2 close to the torque wrench 1, so that the interference with the normal function of the wrench socket 2 is avoided; the welding point has enough strength and cannot damage the strength and the appearance of the original sleeve and the original wrench.
