Problems solved by technology

[0002] The opening width of the traditional adjustable wrench can be adjusted within a certain range. It is used to tighten and loosen nuts and bolts of different specifications. However, due to the large head of the adjustable wrench, when working in a narrow space, the adjustable wrench takes up more space Large, hard to tighten or loosen screws
Although the fixed-size ring wrench or open-end wrench can handle the work in a small area, the size of the ring wrench or open-end wrench is fixed. When working on multiple nuts or bolts of different sizes in the same area, it needs to be carried according to different nuts or bolts. Corresponding wrench, poor versatility
The traditional adjustable wrench, fixed-size ring wrench or open-end wrench cannot take into account the versatility and portability at the same time, and it is difficult to meet the operation needs of specific scenarios in the power industry

Embodiment 1

[0016] figure 1 A structural schematic diagram of an integrated multifunctional wrench provided for this embodiment, as shown in the figure, the integrated multifunctional wrench includes an opening part 1 and a handle part 2 connected to the opening part 1, and the handle part 2 A plum blossom garland 3 is arranged on it; the opening part 1 includes a movable plate lip 6 and a rigid lip 5 , and also includes an adjustable wrench worm wheel 4 .

[0017] Wherein, the number of the plum blossom garlands 3 is five; the movable lip 6 and the rigid lip 5 are respectively provided with anti-slip grooves.

[0018] When using an adjustable wrench to tighten the bolts and nuts, the operator holds the handle part 2 in the figure with his hand to perform operations. When turning a large nut, a larger torque is often used, and the hand should be held near the end of the handle; when turning a small nut, the torque used is not large, but the nut is too small and easy to slip, so the hand ...

Abstract

The invention relates to an integrated multifunctional wrench. The integrated multifunctional wrench comprises an open part and a handle part connected with the open part. Plum blossom rings are arranged on the handle part, and the number of the plum blossom rings is one or more. The open part comprises a movable plate lip and a fixed plate lip and further comprises a movable wrench worm wheel. Antiskid grooves are formed in the movable plate lip and the fixed plate lip correspondingly. Compared with a traditional wrench, the integrated multifunctional wrench has universality and portability at the same time, and the operation requirement for efficient tightness of nuts and bolts of multiple sizes in the same operation area can be met. When a movable handle is needed for carrying out tightness operation on the nuts or bolts of multiple sizes in a specific area, inconvenience of carrying multiple solid wrenches can be omitted by carrying the integrated multifunctional wrench, and the loads of operation personnel can be relieved; and during aerial operation, the hitting risk generated by object falling from high altitudes when the wrench is replaced many times can be effectively reduced.
