[0039] When in use, the fixed plate 101 is rotated to a suitable position and one end of the rotating plate 103d is pressed. At this time, the rotating plate 103d will rotate around the fixed axis 103c, which will drive the first clamping block 103f away from the second clamping slot 102c, releasing the fixation of the movable plate 102a. When the movable plate 102a is fixed, the first spring 102b is in a compressed state. After the fixation is released, the first spring 102b will push the movable plate 102a to move. At this time, the movable plate 102a will be inserted into the first placement slot 203b or the second placement slot 203c to fix the fixed plate 101. Due to the cooperation between the first pushing block 102d and the first through slot 101e, the moving distance of the movable plate 102a can be limited. When the fixed plate 101 is fixed, the firefighter can operate the wrench body 201 through the fixed plate 101.

[0040] Example 3

[0041] 4 to 6 , a third embodiment of the present invention is shown, which is based on the first two embodiments. This embodiment provides a fire hydrant wrench, comprising an external component 200. The external component 200 comprises a wrench body 201, a third groove 202 provided on one side of the wrench body 201, a placement piece 203 provided at one end of the wrench body 201, and a second fixing piece 204 installed in the wrench body 201. The third groove 202 is adapted to the fixing frame 103b, the placement piece 203 is connected to the first connecting plate 101c, and the fixing plate 101 can be fixed by the second fixing piece 204, which can prevent the fixing plate 101 from being fixed to a horizontal state when not in use, thereby saving the space occupied by the wrench body 201 and making it easy to carry.

[0042] Specifically, the placement piece 203 includes a fixed block 203a fixed to one end of the wrench body 201, a second fixed rod 203d fixed on both sides of the fixed block 203a, and a first placement groove 203b and a second placement groove 203c opened on the fixed block 203a. The first placement groove 203b and the second placement groove 203c are perpendicular to each other. The first placement groove 203b and the second placement groove 203c are adapted to the movable plate 102a. The second fixed rod 203d is rotatably connected to the fixed shaft 103c through a bearing. The rotation cooperation between the fixed shaft 103c and the second fixed rod 203d facilitates the rotation of the fixed plate 101.

[0043] Specifically, the second fixing member 204 includes a fourth groove 204a and a fifth groove 204b provided in the wrench body 201, a second spring 204c arranged in the fifth groove 204b, and a second clamping block 204d sliding in the fifth groove 204b. The fourth groove 204a and the fifth groove 204b are connected, and the two ends of the second spring 204c are respectively fixed to one side of the second clamping block 204d and the inner wall of the fifth groove 204b. The fifth groove 204b can push the second clamping block 204d, which will bring a thrust to the second clamping block 204d, so that it can be firmly fixed in the first clamping groove 101a, thereby fixing the fixing plate 101.

[0044] Specifically, a second push block 204e is slidably connected in the fourth groove 204a, and the second push block 204e is fixed to one side of the second card block 204d through the second connecting plate 204f. The second card block 204d cooperates with the first card slot 101a. By controlling the second push block 204e, the control of the fixed plate 101 can be released. At the same time, the setting of the second push block 204e also prevents the second push block 204e from being accidentally touched during carrying, which causes the fixed plate 101 to be released.

[0045] When in use, push the second pushing block 204e, and the movement of the second pushing block 204e can drive the second clamping block 204d to move through the second connecting plate 204f, and the second spring 204c will be compressed during the movement. When the second clamping block 204d moves to a suitable position, the fixing plate 101 can be released and the fixing plate 101 can be rotated. When use is finished, it is only necessary to rotate the fixing plate 101 to be level with the wrench body 201. During the rotation, the first clamping groove 101a contacts the second clamping block 204d, which will drive the second clamping block 204d to move. When the fixing plate 101 is rotated to the horizontal, the second clamping block 204d will move due to the thrust of the second spring 204c, thereby fixing the fixing plate 101.

[0046] In summary, when in use, the second pushing block 204e is pushed, and the movement of the second pushing block 204e can drive the second clamping block 204d to move through the second connecting plate 204f, and the second spring 204c will be compressed during the movement. When the second clamping block 204d moves to the appropriate position, the fixed plate 101 can be released and the fixed plate 101 can be rotated. When the fixed plate 101 is rotated to the appropriate position, one end of the rotating plate 103d is pressed. At this time, the rotating plate 103d will rotate around the fixed axis 103c, and it will drive the first clamping block 103f to move away from the second clamping slot 102c, releasing the fixation of the movable plate 102a. When the movable plate 102a is fixed, the first spring 102b is in a compressed state. After the fixation is released, the first spring 102b will push the movable plate 102a to move. At this time, the movable plate 102a will be inserted into the first placement slot 203b or the second placement slot 203c to fix the fixed plate 101 is fixed, and due to the cooperation of the first pushing block 102d and the first through groove 101e, the moving distance of the movable plate 102a can be limited. When the fixed plate 101 is fixed, the firefighter can operate the wrench body 201 through the fixed plate 101. After use, the first pushing block 102d is pulled, and the movement of the first pushing block 102d will drive the movable plate 102a to move, and at the same time, the first spring 102b will be squeezed. When the second slot 102c is engaged with the first clamping block 103f, the movable plate 102a can be fixed, and then the fixed plate 101 is rotated to be level with the wrench body 201. During the rotation process, the first clamping groove 101a contacts the second clamping block 204d, which will drive the second clamping block 204d to move. When the fixed plate 101 is rotated to the horizontal position, the second clamping block 204d will move due to the thrust of the second spring 204c, thereby fixing the fixed plate 101.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
