[0002] Tool wrenches, which are widely used in the machinery manufacturing and maintenance industries, have long been the only choice for the modern machinery manufacturing industry because of their ease of use and labor-saving.

[0003] There are many types of existing wrenches, which mainly include a handle and a head. Most of them have only one fixed wrench head with a single function and can only achieve the tightening and loosening of a certain type of bolt or pipe fitting. Most of the existing wrenches have only two clamping blocks on the wrench head, which are put on the workpiece in an open form to tighten or loosen the workpiece without reinforcement, which can easily cause the workpiece to loosen and run idle.

[0004] A wrench is proposed in the patent document with publication number CN215968476U. The device includes a handle and a first wrench head located at one end of the handle. The first wrench head includes a first fixed part fixedly connected to the handle and a first movable part movably connected to the first fixed part. The first fixed part and the first movable part form a first opening part with an adjustable size. The first fixed part is axially fixed and circumferentially rotatably provided with an adjusting screw. The first movable part is fixedly connected with an adjusting thread. The adjusting thread and the adjusting screw are meshed and transmitted. A second wrench head for locking the pipe connection is provided at the other end of the handle. The second wrench head includes a through hole adapted to the pipe fitting and adjustable in size, a second fixed part fixedly connected to the handle, and a second movable part hingedly connected to the second fixed part. The adjusting rod passes through the second movable part and the second fixed part. The insertion and extraction length of the adjusting rod determines the tightness of the pipe fitting in the wrench. Grooves are provided on both the fixed wrench head and the movable wrench head, and the grooves have an anti-slip effect.
