For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The utility model provides the following technical solutions:

[0029] Embodiment 1

[0030] Combination Figures 1 to 5 A portable fire hydrant wrench comprises a wrench 1, an adjusting mechanism 3 is arranged on the right side of the wrench 1, a wrench 2 is arranged on the right side of the adjusting mechanism 3, and a positioning mechanism 4 is arranged on the front side of the wrench 2;

[0031] The adjusting mechanism 3 comprises a threaded barrel 31, which is arranged inside the wrench 2, a threaded rod 32 is threadedly connected to the inner wall of the threaded barrel 31, a torque sleeve 33 is fixedly connected to the outer wall of the threaded barrel 31, a long groove 34 is opened inside the wrench 1, a rectangular plate 36 is slidably connected inside the long groove 34, and a long block 35 is fixedly connected to the right side of the rectangular plate 36.

[0032] Furthermore, the side of the long block 35 away from the rectangular plate 36 is fixedly connected to the left side of the wrench 2, and the threaded rod 32 is fixedly connected to the right side of the wrench 1, so that the wrench 1 can move stably.

[0033] Furthermore, a moving opening is opened on the right side of the wrench 1, and the long block 35 passes through the moving opening and moves, so that the long block 35 can move through the moving opening.

[0034] Furthermore, a rotating hole is provided inside the wrench 2, and the threaded barrel 31 is rotatably connected to the inner wall of the rotating hole, so as to provide stable support for the threaded barrel 31.

[0035] Embodiment 2

[0036] See also Figures 1 to 5 On the basis of the first embodiment, the positioning mechanism 4 further comprises a fixed box 41, the fixed box 41 is fixedly connected to the front of the wrench 2, a spring 42 is fixedly connected to the inner wall of the fixed box 41, a moving plate 43 is fixedly connected to the left end of the spring 42, a clamping shaft 45 is fixedly connected to the left side of the moving plate 43, and a push block 44 is fixedly connected to the front of the moving plate 43, so as to further improve the stability of the adjustment.

[0037] Furthermore, the movable plate 43 is slidably connected to the inner wall of the fixed box 41 , a clamping hole is opened on the right side of the torsion sleeve 33 , and the clamping shaft 45 is movably connected to the inner wall of the clamping hole to limit the torsion sleeve 33 .

[0038] Furthermore, a rectangular opening is opened on the front side of the fixed box 41, and the push block 44 passes through the rectangular opening, so that the push block 44 can move through the rectangular opening.

[0039] In actual operation, when this device is used, when the overall length of the device needs to be adjusted, the push block 44 can be pushed so that the push block 44 can drive the movable plate 43 to move and compress the spring 42. At the same time, the push block 44 will also drive the clamping shaft 45 to disengage from the inner wall of the clamping hole opened by the torque sleeve 33 through the movable plate 43, thereby canceling the limit on the clamping hole. At this time, the torque sleeve 33 can be in a rotatable state, which is convenient for further adjustment of the length. At the same time, under the elastic action of the spring 42 and the limit action of the clamping shaft 45, the stability of the adjustment can be guaranteed, and deviation and shaking will not easily occur, thereby ensuring normal operation.

[0040] When the limit on the torque sleeve 33 is cancelled, the torque sleeve 33 can be rotated so that the torque sleeve 33 can drive the threaded barrel 31 to rotate. Since the threaded rod 32 is threadedly connected to the inner wall of the threaded barrel 31, the rotation of the threaded barrel 31 will drive the threaded rod 32 to move out from the inside of the threaded barrel 31, and the threaded rod 32 can push the wrench 1 to move. At the same time, the long block 35 can drive the rectangular plate 36 to slide and limit on the inner wall of the long groove 34, so that the wrench 1 can move stably, so that the device has the function of adjusting the length, can adapt to fire hydrants of different types and heights, and enhance the flexibility of the device.

[0041] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
