Its special feature is that the movable gripper is equipped with a threaded rod, which can be freely plugged into the hole of the fixed gripper, and the movable wrench can be fixed on the fixed wrench by tightening the nut, so that different types of hexagonal The nut is locked. The fixed gripper is equipped with a steering joint through the positioning shaft, and the connecting shaft and the hollow connecting shaft are connected through the steering joint. The connecting shaft and the hollow connecting shaft can be infinitely connected through an elbow, so that the handle of the wrench can be extended to a suitable working position , easy to operate. The wrench has the characteristics of simple structure, purely mechanical operation, small space occupation, and can be applied to various narrow spaces.

Description

A new type of universal wrench

Technical field:

The utility model relates to a novel universal wrench, which is suitable for pinching nuts in various narrow spaces.

Background technique:

At present, the general open end wrench has a flexible opening, and a wrench can be adapted to various screws and nuts of different sizes. This kind of wrench has a history of hundreds of years, but under certain occasions, especially in a narrow space, the wrench is difficult to put in, or it is very inconvenient to operate after putting it in. Due to space constraints, only a small angle can be pinched each time, or the force cannot be well received, and it is difficult to complete normal operations, resulting in laborious, time-consuming, and laborious work, which seriously affects work efficiency.

Invention content:

The purpose of this utility model is to provide a new type of universal wrench, which can not only adapt to screws and nuts of different sizes, but also realize fast, convenient, time-saving and labor-saving rotation of nuts in a narrow space, which can be extremely Greatly improve work efficiency.

The technical scheme that the utility model adopts when solving its technical problem is:

A new type of universal wrench, including a fixed gripper, a movable gripper arranged on the fixed gripper, a nut for locking the movable gripper, a steering joint arranged on the fixed gripper through a positioning shaft, and a There are threads, and the steering joint and the hollow connecting shaft are connected by a connecting shaft. An elbow is arranged on the hollow connecting shaft, and a thread is arranged inside the elbow. Its special feature is that the movable gripper is equipped with a threaded rod, which can be freely plugged into the through hole of the fixed gripper, and at the same time, the movable gripper can be fixed on the fixed gripper by tightening the nut, so that different Model hex nuts for locking. The fixed gripper is equipped with a steering joint through the positioning shaft. The steering joint can rotate a certain angle around the positioning shaft according to the work needs. The connecting shaft and the hollow connecting shaft are connected through the steering joint. The connecting shaft and the hollow connecting shaft can be infinitely adjusted through the elbow. connection, so that the handle of the wrench is extended to a suitable working position for easy operation. The wrench has the characteristics of simple structure, small space occupation, and can be applied to various narrow and small spaces.

detailed description:

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to Figure 1, a new type of universal wrench includes a fixed gripper 3, a movable gripper 1 arranged on the fixed gripper 3, a nut 2 for locking the movable gripper 1, and a positioning shaft 4 arranged on the fixed gripper 3 on the steering joint 5, the steering joint 5 is provided with threads, the steering joint 5 and the hollow connecting shaft 8 are connected by the connecting shaft 6, the hollow connecting shaft 8 is provided with an elbow 9, and the elbow 9 is provided with threads, the hollow The connecting shaft 8 is provided with a positioning pin 7 .

Referring to Figure 1 and Figure 2, the movable gripper 1 is provided with a threaded rod, which can be freely plugged into the through hole provided on the fixed gripper 3, and the movable gripper 1 can be fixed on the fixed gripper by tightening the nut 2 Hand 3, so that the clamping distance between the fixed gripper and the movable gripper 1 can be freely set for locking different types of hex nuts.

Referring to Fig. 1 and Fig. 3 and Fig. 4, a steering joint 5 is installed on the fixed gripper 3 through a positioning shaft 4. According to the requirements of the working space, the steering joint 5 can be rotated around the positioning shaft 4 by a certain angle, and then locked by a nut. Be provided with thread in the steering joint 5, be used for installing connecting shaft 6.

Referring to Fig. 1, Fig. 4 and Fig. 5, the threaded end of the connecting shaft 6 can be connected with the steering joint 5; the non-threaded end of the connecting shaft 6 can be freely plugged into the non-threaded end of the hollow connecting shaft 8, and the length can be adjusted according to the length required by the work. Then lock by the positioning pin 7; the threaded end of the connecting shaft 6 and the threaded end of the hollow connecting shaft 8 can be connected by an elbow 9.

When the wrench works in a narrow space, the angle of the steering joint 5 can be rotated, and the distance between the threadless end of the telescopic connecting shaft 6 and the threadless end of the hollow connecting shaft 8 can be used to thread the connecting shaft 6 infinitely through the elbow 9. The end is connected with the hollow connecting shaft 8, so that the handle of the wrench is extended to a suitable working position for easy operation.
