[0023] See also Figure 2-3 The buffer component 3 in this embodiment includes two protective sleeves 301 arranged on the outer surface of the handle 2, and the protective sleeves 301 are in a semi-ring shape. The buffer component 3 also includes a plurality of abutment blocks 302 abutting against the left and right ends of the outer surface of the handle 2. A pressure plate 303 is fixed on the opposite side of the left and right groups of abutment blocks 302. A support rod 304 is slidably connected inside the pressure plate 303. A baffle 305 is fixed on the opposite ends of the left and right groups of support rods 304. A buffer spring 306 is sleeved on the outer surface of the support rod 304. A plurality of grooves 307 are provided on the inner sides of the two protective sleeves 301.

[0024] Among them, the rear sides of the two protective sleeves 301 are hingedly connected, the two support rods 304 of the same group are located inside the groove 307 and fixed thereto, and the abutment block 302 is located inside the groove 307, and the abutment block 302 and the groove 307 are slidably connected, so that the abutment block 302 can be moved into or into the protective sleeve 301, which can reserve sufficient space for vibration buffering of the handle 2.

[0025] In addition, two through holes are provided on opposite sides of the left and right pressure plates 303 , and the support rod 304 passes through the outside of the through holes and is slidably connected thereto, so that the pressure plates 303 can slide on the support rod 304 so as to squeeze the buffer spring 306 .

[0026] See also Figure 4 The disassembly and assembly component 4 in this embodiment includes a block 401 hingedly connected to the front end of the left protective sleeve 301, and the disassembly and assembly component 4 also includes a concave plate 402 fixed to the front end of the right protective sleeve 301. A plug rod 403 is inserted into the interior of the block 401, and the plug rod 403 is T-shaped. The outer surface of the plug rod 403 is slidably connected to the first horizontal plate 404 and the second horizontal plate 406 respectively. Connecting holes are provided on the opposite sides of the first horizontal plate 404 and the second horizontal plate 406 to facilitate the plug rod 403 to slide in the first horizontal plate 404 and the second horizontal plate 406. A return spring 405 is sleeved on the outer surface of the plug rod 403.

[0027] Secondly, a limiting hole is opened on the top of the block 401, and the insertion rod 403 passes through the outside of the limiting hole and is plugged into it, so that the block 401 can be fixed in the concave plate 402, thereby facilitating the fixing of the two protective sleeves 301 on the handle 2.

[0028] In addition, the upper and lower ends of the inner side of the concave plate 402 are respectively provided with a plug hole and a slot, and the plug rod 403 passes through the plug hole to the inside of the slot and is plugged therein, so that the plug rod 403 can pass through the inner side of the concave plate 402.

[0029] At the same time, the first transverse plate 404 is located inside the socket and fixed thereto, and sliding grooves are provided at both left and right ends of the inner cavity of the socket. The left and right ends of the second transverse plate 406 are located inside the sliding grooves and are slidably connected thereto, so that the second transverse plate 406 can slide in the socket. When the insertion rod 403 moves upward, it can drive the second transverse plate 406 to slide in the socket, so that the first transverse plate 404 and the second transverse plate 406 cooperate with each other to squeeze the reset spring 405.

[0030] The working principle of the above embodiment is:

[0031] When the tool is in use, the vibration of the tool head body 1 is transmitted to the handle 2, so that the handle 2 presses the abutment block 302, so that the abutment block 302 can push the pressure plate 303 to move, so that the pressure plate 303 can slide on the support rod 304, and the pressure plate 303 can press the buffer spring 306, so as to reduce the vibration sense transmitted to the hand of the staff by the handle 2, which can effectively prevent the staff from getting numb in the hand due to the impact of the vibration when holding the tool handle, and improve the comfort of the staff when using it; and when When the two protective covers 301 need to be removed from the device for replacement (or cleaning), pull the insertion rod 403 upward to move the insertion rod 403 out of the slot of the concave plate 402 and the limiting hole of the block 401, so that when the insertion rod 403 moves, it can drive the second cross plate 406 to move upward, and the first cross plate 404 can cooperate with the second cross plate 406 to squeeze the reset spring 405, so that the block 401 can be flipped out of the concave plate 402, so that the two protective covers 301 can be removed from the device for replacement and cleaning.
