Problems solved by technology

[0002] A wrench is a common tool for screwing screws. Usually, a wrench is composed of a fixed pliers and a moving pliers. The wrench is driven by a screw to clamp or loosen the two pliers. The current wrench is composed of a very long wrench. It is composed of a handle and a wrench head. When using it, the screw at the end of the wrench needs to be tightened or loosened by hand. This is extremely inconvenient or even unsuitable for some narrow spaces, especially in narrow spaces with a certain height. It is impossible for human hands to reach into the corresponding position to adjust the gap between the two clamps to achieve clamping, which brings great trouble to the daily installation work of the majority of engineers.

Embodiment Construction

[0019] The embodiments of the present invention are described below by specific embodiments, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0020] Below in conjunction with accompanying drawing and embodiment, the present invention will be further described:

[0021] like figure 1 As shown, a body 1 comprising a strip and plate shape, the width of the upper part 101 of the body 1 is smaller than the width of the lower part 102, so that the upper part can be used as a working part more easily to work in a narrow space, while the lower part is set larger Easy to hold when necessary.

[0022] The top of the upper part 101 of the main body 1 is integrally provided with a fixing forceps 2 which is perpendicular to the length direction of the body 1 . A groove 3 is opened in the length direction, and a lead screw 4 is arranged in the groove 3 along its length direction. T...

Abstract

The invention discloses a wrench. The wrench comprises a strip-shaped and plate-shaped body. The upper width of the body is smaller than the width of the lower portion of the body. A fixed clamp perpendicular to the length direction of the body is integrally arranged at the top end of the upper portion of the body, the fixed clamp protrudes out of the side surface of the upper portion of the body,and a lead screw is arranged in a groove in the upper portion in the length direction of the groove; and a movable clamp parallel to the fixed clamp are screwed to the lead screw. The shaft neck sections of the two ends of the lead screw are correspondingly located in the side walls of the two ends of the groove. A transmission cavity is formed inside the lower part of the body. A worm gear mechanism is arranged in the transmission cavity. A worm is coaxially connected with one end of the lead screw, a shaft of a worm wheel is connected with one end of an adjustment rod, and the other end ofthe adjustment rod penetrates out of the end face of the lower portion of the body and can freely rotate in the body. The penetrating-out end of the adjustment rod is connected with one end of an L-shaped connecting rod, and a rocking handle is arranged at the other end of the connecting rod. The wrench can be used in a narrow space and is extremely high in adaptability.

Description

technical field [0001] The invention belongs to the technical field of wrenches, and in particular relates to a wrench which is convenient to be used in a narrow space. Background technique [0002] A wrench is a common tool for screwing screws. Usually, the wrench is composed of a fixed pliers and a movable pliers. The wrench is driven by a screw to realize the clamping or loosening of the two pliers. At present, the wrench is composed of a very long wrench. The handle is composed of a wrench head, and the screw at the end of the wrench needs to be tightened or loosened by hand. This is extremely inconvenient or even unsuitable for some narrow spaces, especially narrow spaces with a certain height. It is impossible for the human hand to reach the corresponding position to adjust the gap between the two clamps to achieve clamping, which brings great trouble to the daily installation work of the majority of engineers. SUMMARY OF THE INVENTION [0003] The purpose of the pr...
