Description

Special wrench for screw insurance cover

technical field

The utility model relates to a power tool device, in particular to a special wrench for a screw insurance cover.

Background technique

The screw-on safety cover cannot be tightened during installation because the threaded thread is too tight or the threaded thread has errors, resulting in poor contact and causing a fault, which needs to be replaced. Long-term operation causes heat and sticks or oxidizes and sticks, making it impossible to unscrew. When a failure occurs, it can only be destroyed. This not only wastes materials, but also wastes time, and it is necessary to open the distribution transformer to deal with power outages, which not only increases the workload and danger, but also affects the normal electricity consumption of many residents. Therefore, it is necessary to provide a new technical solution to Solve the above problems.

Invention content:

The purpose of the utility model is to provide a special wrench for the screw insurance cover which is convenient and fast, and can safely open and tighten the screw insurance cover.

The technical scheme that the utility model adopts is:

The special wrench for the screw insurance cover includes a handle and an annular iron ring. The side of the annular iron ring is uniformly provided with a plurality of holes along the circumference, and a tightening and fixing device is provided in the hole. An iron sheet is arranged, and the middle part of the iron sheet is fixedly connected with the handle.

The tightening and fixing device includes a nut and a screw fixed in the hole, and the nut is threadedly connected with the screw.

The number of the holes is 2-5.

The special wrench for the screw insurance cover of the utility model includes a handle and an annular iron ring. The side of the annular iron ring is uniformly provided with a plurality of holes along the circumference, and a tightening and fixing device is arranged in the hole. An iron piece is fixed on the end surface, and the middle part of the iron piece is fixedly connected with the handle. After adopting such a structure, by adjusting the length of the screw access hole and tightening the screw to fix the screw safety cover, the RT1---200A, RT1- --100A different types of screw safety, apply force through the wrench handle at the same time, the force is more uniform, save labor and will not cause damage to the screw safety cover, saving resources. The tightening and fixing device includes a nut and a screw fixed in the hole, and the nut is threadedly connected with the screw, so that the wrench can easily fix and loosen the screw safety cover by tightening and unscrewing the screw, so that simply applying force can The screw-on safety cover can be unscrewed and tightened. The number of the holes is 2-5, so that the fixing and unscrewing of the screw insurance cover can be easily completed by adjusting the screws evenly distributed on the side of the annular iron ring along the circumference.

The utility model has the advantages of safe operation, simple and convenient operation, not only saving resources, but also improving maintenance quality and work efficiency.
