[0018] 1. By incorporating a handheld handle, a telescopic rod, a pin, and a locking hole, the device can be disengaged from the tilt block by rotating the clamping nut when it needs to be carried. This causes the connecting spring to support the tilt block, disengaging one end of the pin from the locking hole. The telescopic rod can then be moved to retract inside the handheld handle. Rotating the clamping nut again causes its inner wall to abut against the tilt block, allowing the pin to engage with the locking hole below and secure the telescopic rod. This shortens the overall length of the device, making it easier to carry using a carrying strap.

[0019] 2. By setting up a protective shell, drive shaft, bevel gear and first blade, the user can turn on the motor to drive the connecting shaft and second blade to rotate, so as to cut the weeds, which helps to quickly open up the road in the fire scene. When the second blade rotates, the spur gear will also drive the rotating shaft to rotate, and the rotating shaft will also drive the drive shaft and the first blade to rotate through the bevel gear, so as to cut the cut weeds again and prevent them from getting tangled.

[0020] 3. By setting up a mounting block, an arc-shaped baffle, and connecting screws, the user can fix the mounting block to the mounting plate using the connecting screws. The arc-shaped baffle is installed on one side of the second blade, thereby blocking the debris generated during cutting and preventing it from affecting the normal use of the device, facilitating long-term operation.

[0031] In this embodiment, a rotating shaft 12 is rotatably provided at the lower end of the mounting plate 10 and on both sides. A motor 13 is provided at the middle position of the two rotating shafts 12 and on the upper end surface of the mounting plate 10. A spur gear 14 is provided on both the output end of the motor 13 and the rotating shaft 12. Multiple spur gears 14 are meshed and installed. A transmission shaft 15 is rotatably provided on both sides of the inner wall of the protective shell 11. A bevel gear 16 is fixedly provided on both the transmission shaft 15 and the rotating shaft 12. Two bevel gears 16 are meshed and installed. A connecting shaft 17 is rotatably provided at the lower end surface of the protective shell 11 and in the middle position. The upper end of the connecting shaft 17 is fixedly connected to the output end of the motor 13. A first blade 18 is provided at one end of the transmission shaft 15, and a second blade 19 is provided at the lower end of the connecting shaft 17.

[0032] More specifically, when the device needs to be carried, the clamping nut 9 can be turned to disengage it from the tilting block 7. At this time, the connecting spring 8 will support the tilting block 7, allowing one end of the pin 6 to disengage from the locking hole 3. Then, the telescopic rod 2 can be moved to retract inside the hand handle 1. Then, the clamping nut 9 can be turned again to make its inner wall abut against the tilting block 7, so that the pin 6 enters the locking hole 3 located below to fix the telescopic rod 2. At this time, the overall length of the device will be shortened to facilitate carrying the device via the shoulder strap 26. The user can turn on the motor 13 to drive the connecting shaft 17 and the second blade 19 to rotate, so as to cut the weeds, thereby helping to quickly open up roads in the fire scene. When the second blade 19 rotates, the spur gear 14 will also drive the rotating shaft 12 to rotate. The rotating shaft 12 will also drive the transmission shaft 15 and the first blade 18 to rotate through the bevel gear 16, so as to cut the cut weeds again and prevent entanglement.

[0033] Please see Figure 1 , Figure 3 and Figure 5 As an implementation method for shielding the cut weeds: the lower end face of the mounting plate 10 is provided with a mounting block 20, and the lower end face of the mounting block 20 is fixedly provided with an arc-shaped baffle 21. The arc-shaped baffle 21 and the mounting block 20 are both located on one side of the second blade 19. The mounting block 20 and the outer wall of the mounting plate 10 are both provided with connecting holes 22, and the interior of the connecting holes 22 is provided with connecting screws 23.

[0034] Specifically, the user can use the connecting screws 23 to fix the mounting block 20 to the mounting plate 10 so that the arc-shaped baffle 21 can be installed on one side of the second blade 19, thereby blocking the debris generated during cutting and facilitating long-term use.

[0035] Please refer to Figure 1 As a further embodiment for carrying the device: a shoulder strap 26 is fixedly provided on the outer wall of the handheld rod 1.

[0036] Specifically, the user can carry the device using the shoulder strap 26.

[0037] In summary, when using the entire device: the user can turn on the motor 13 to drive the connecting shaft 17 and the second blade 19 to rotate, thus cutting weeds and facilitating the rapid clearing of paths in a fire. Simultaneously, as the second blade 19 rotates, the spur gear 14 drives the rotating shaft 12, which in turn drives the transmission shaft 15 and the first blade 18 via the bevel gear 16, further cutting the weeds and preventing entanglement. Before cutting, the mounting block 20 can be fixed to the mounting plate 10 using the connecting screws 23, allowing the arc-shaped baffle 21 to be installed. The second blade 19 is positioned on one side to block the debris produced during cutting, facilitating long-term use. When the device needs to be carried, the clamping nut 9 can be rotated to disengage it from the tilting block 7. At this time, the connecting spring 8 will support the tilting block 7, allowing one end of the pin 6 to disengage from the locking hole 3. Then, the telescopic rod 2 can be moved to retract inside the hand handle 1. The clamping nut 9 can then be rotated again to make its inner wall abut against the tilting block 7, allowing the pin 6 to enter the locking hole 3 located below, thus fixing the telescopic rod 2. At this time, the overall length of the device will be shortened, making it easier to carry the device via the shoulder strap 26.
