[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] This utility model embodiment provides a hand-held tool for carrying air cylinders of breathing apparatus. Please refer to [link / reference]. Figures 1-6 As shown, it includes a handle 1, a hook 2, a gas cylinder 5, and an adjustment device 3. The two sides of the handle 1 are connected to the hook 2, which is attached to the neck of the gas cylinder, through the adjustment device 3. The hook 2 is attached to the neck of the gas cylinder 5. The adjustment device 3 is located on one side of the handle 1.

[0023] The specific settings and functions of the adjustment device 3 and the disassembly device 4 will be explained in detail below.

[0024] In this embodiment: the adjustment device 3 includes a slide bar 35, which is connected to the grip 1 by a return spring 34. A pin 33 is fixedly connected to the lower side of the slide bar 35. Connecting blocks 37 are rotatably connected to both sides of the grip 1 by connecting rods 38. A hook 2 is fixedly provided at the other end of the connecting block 37. A storage block 31 is fixedly connected to one side of the connecting block 37. The other end of the connecting rods 38 on both sides of the grip 1 is located between the storage block 31 and the connecting block 37. Several storage slots 32 are formed on the outer surface of the storage block 31, and the pin 33 is inserted into the storage slots 32 for connection. A rubber layer is installed on the surface of the grip 1 and the inner side of the hook 2, which is beneficial for anti-slip, sweat absorption, or comfort.

[0025] In this embodiment, support blocks 36 are fixedly connected to both ends of the grip 1, and return springs 34 are fixedly connected between the support blocks 36 on both sides and the slider 35. The return springs 34 are used to push the slider 35 away from the grip 1.

[0026] When it is necessary to move the air cylinder of the self-contained breathing apparatus, the operator places the hook 2 horizontally on the neck of the air cylinder 5, with the upper surface of the air cylinder 5 supporting the hook 2. Holding the handle 1, the operator pulls the slider 35 towards the handle 1, causing the slider 35 to disengage the pin 33 from the storage slot 32. Then, the operator rotates the handle 1 upwards by 90 degrees. When the handle 1 is perpendicular to the hook 2, the operator releases the slider 35, and the return spring 34 pushes the slider 35 back to its original position. The slider 35 then pushes the pin 33 into the storage slot 32. At this point, the operator lifts the handle 1, which, through the connecting block 37, moves the hook 2, lifting the air cylinder. The neck of the air cylinder rests on the hook 2. The rubber layer on the inner surface of the hook 2, the neck of the air cylinder, and the rubber layer on the surface of the handle 1 help protect the equipment and the operator's hands.

[0027] In this embodiment, a disassembly device 4 is provided below the handle 1 between the connecting block 37 and the hook 2. The disassembly device 4 includes a slot 43 opened on one side of the handle 1. The slot 43 is opened on the side of the connecting block 37. The placement block 44 is connected to the hook 2 and is disposed inside the slot 43. The slot 43 houses the placement block 44.

[0028] The connecting block 37 is internally threaded with a threaded rod 42, and the slot 43 is internally fixedly connected with a stabilizing rod 41. The threaded rod 42 and the stabilizing rod 41 are respectively connected to the insertion hole 46 and the sleeve hole 45 opened on the placement block 44. The internal insertion of the threaded rod 42 into the insertion hole 46 effectively restricts the sliding of the placement block 44, and the sleeve hole 45 is sleeved on the outer surface of the stabilizing rod 41 to effectively accommodate the threaded rod 42.

[0029] The disassembly device 4 is provided so that when a worn hook 2 needs to be replaced, the threaded rod 42 can be rotated with an auxiliary tool until it disengages. The threaded rod 42 can be removed, and the hook 2 can be pushed to disengage the placement block 44 from the stabilizing rod 41 and the slot 43. Then, the new hook 2 can be installed. The disassembly device 4 facilitates the quick replacement of worn hooks 2, allows operators to maintain tools quickly, and eliminates the time-consuming and laborious situation of replacing damaged hooks.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
