When workers need to perform maintenance and polishing work on fire-fighting equipment using this device, they first pull the sliding rod according to their hand size. The sliding rod causes the pressure plate and toothed plate to move, disengaging the toothed plate from the outside of the positioning strip. Then, the worker rotates the rotating roller, which allows them to pull the positioning strip to a length suitable for their hand. After gripping the handle at the designated position, the worker pulls the positioning strip to ensure it fits snugly against the outside of their palm. Releasing the sliding rod allows the spring force to move it, moving the pressure plate and toothed plate to the designated position. This allows the toothed plate to press and position the adjusted positioning strip, preventing it from slipping. This ensures the device fits snugly against the user's hand, preventing accidental slippage and improving maintenance efficiency and safety. Attached Figure Description

[0030] The first connecting plate 14 is provided with a positioning bolt 15 inside. By rotating the positioning bolt 15, the positioning bolt 15 enters the interior of the first connecting plate 14 and the second connecting plate 16, thereby allowing the first protective cover 3 and the second protective cover 11 to be tightly connected. At the same time, the inner ring of the sealing ring 12 can be tightly fitted with the outer side of the motor 9. There are two first connecting plates 14. The outer side of the first protective cover 3 is fixedly connected to the second connecting plate 16. The second connecting plate 16 is provided with a positioning hole 17 inside. By providing the positioning hole 17, the positioning bolt 15 can enter its interior, thereby allowing the two protective covers to be tightly connected. At the same time, it is convenient for the user to disassemble and clean the two protective covers. There are two second connecting plates 16.

[0031] Working principle: When workers use this device to grind and repair fire-fighting equipment, they first adjust the length of the positioning belt 2 according to the size of their hand, and pull the sliding rod 403. Under the action of the sliding rod 403, the pressure plate 404 and the toothed plate 6 can be moved, thereby causing the toothed plate 6 to disengage from the outside of the rotating roller 402. Then, the user pulls the positioning belt 2 so that its length can fit the user's palm. Then, the user places their palm on the outside of the friction sleeve 7, bends their five fingers, and grips the handle 1. Then, the rotating roller 402 is rotated. The positioning belt 2 is wound up by the lower drive. After the positioning belt 2 is tightly pressed against the outside of the palm on one side, the sliding rod 403 is released. Under the elastic force of the spring 5, the toothed plate 6 can be moved by the pressure plate 404. Then, under the action of multiple toothed plates 6, the positioning belt 2 on the outside of the rotating roller 402 is pressed tightly, so that the positioning belt 2 will not fall off. The positioning belt 2 presses tightly against the user's palm, so that the device will not easily separate from the user's palm, thereby improving the safety of the device during use and preventing the device from slipping out of the hand and causing harm to the surrounding people.
