Description

An oversized bolt fastening tool

technical field

The utility model relates to the technical field of bolt fastening tools, in particular to a super large bolt fastening tool.

Background technique

There are a small number of oversized nuts that need to be tightened during the daily maintenance of the equipment. The oversized adjustable wrench used is large in size and heavy in weight, and cannot be carried by maintenance personnel during daily work. It is necessary to take a special trip to take the wrench and return it before tightening, which is not conducive to eliminating hidden dangers in the first place and increases the risk of personnel safety.

Therefore, a more portable oversized bolt fastening tool is urgently needed to solve the problem that the existing oversized adjustable wrench is inconvenient to carry.

Utility model content

The purpose of this utility model is to provide a super large bolt fastening tool to solve the problems raised in the above-mentioned background technology.

In order to achieve the above object, the utility model provides the following technical solutions:

An oversized bolt fastening tool comprises a square frame, a nut is welded at the center of one side of the square frame, and a screw rod is threadedly connected to the nut.

Further, a handle is welded to the end of the screw rod away from the square frame.

Further, the screw is an elongated screw.

Compared with the prior art, the beneficial effects of the utility model are:

1. When using the utility model, first complete the assembly and screw the screw into the nut, then clamp the square frame to the head of the oversized bolt, and twist the screw so that its end is against the head of the oversized bolt, then hold the end of the screw with your hand and Rotate to realize fastening or dismounting of oversized bolts. When not in use, unscrew the screw from the nut for easy portability;

2. In this embodiment, hold the end of the screw rod tightly when the handle is convenient to use;

3. In this embodiment, the screw rod adopts an extended screw rod to increase the torque and save labor.

To sum up, the utility model effectively solves the problem of inconvenient portability of the existing oversized adjustable wrench, and is light and easy to carry, easy to use, simple in structure and easy to manufacture.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Embodiment 1: Please refer to FIGS. 1-4 , an oversized bolt fastening tool includes a square frame 1 , a nut 2 is welded at the center of one side of the square frame 1 , and a screw rod 3 is threaded on the nut 2 .

When the utility model is in use, first complete the assembly and screw the screw rod 3 into the nut 2, then clamp the square frame 1 to the head of the oversized bolt, and twist the screw rod 3 so that its end is against the head of the oversized bolt, and then hold the screw rod by hand 3 ends and rotate to achieve fastening or disassembly of oversized bolts. When not in use, the screw rod 3 is unscrewed from the nut 2, which is convenient for carrying.

Embodiment 2: Please refer to FIG. 1 , an oversized bolt fastening tool, the difference from Embodiment 1 is that a handle 4 is welded on the end of the screw rod 3 away from the square frame 1 .

In this embodiment, the handle 4 is convenient for holding the end of the screw rod 3 when in use.

Embodiment 3: please refer to FIG. 1 , a super large bolt fastening tool, the difference from Embodiment 1 is that the screw 3 is an elongated screw.

In this embodiment, the screw rod 3 adopts a lengthened screw rod to increase the torque and save labor.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. The equivalent replacement or change of the new technical solution and the concept of the utility model shall be covered by the protection scope of the utility model.
