The arc-shaped tooth design of the rack 18 helps to distribute the load to a longer tooth surface, thereby improving the load capacity and being suitable for occasions that need to withstand a larger torque. The outer wall of the rotating inclined tube 9 is fixedly connected to a motor 2 10, and the driving end of the motor 2 10 is fixedly connected to a gear 2 11. The right outer wall of the rotating inclined tube 9 is a rotating rack 2 12, and the inner wall of the rack 2 12 is fixedly connected to a fixed tube 13. The fixed tube 13 prevents displacement or rupture due to external force or vibration, thereby ensuring the safe operation of the pipeline system. The outer wall of the fixed tube 13 is slidably connected to a disassembly component, and the disassembly component is used to quickly disassemble the nozzle.

[0024] Reference Figure 4 The disassembly component includes a sleeve 14, which can effectively reduce the risk of physical damage such as impact, friction and scratches to the device during daily use, thereby extending the service life of the device. The right outer wall of the fixed tube 13 is fixedly connected to a limit block 15. The limit block 15 can ensure the precise positioning of mechanical components and reduce processing errors or operational errors caused by position deviation. The right outer wall of the fixed tube 13 is provided with a spring 16. The right outer wall of the fixed tube 13 is provided with a plurality of circular grooves 17. The inner wall of the circular groove 17 is slidably connected to a ball 18. When subjected to compression force, the ball 18 exhibits high strength and elasticity and is not prone to plastic deformation. This makes the ball 18 suitable for application scenarios that withstand heavy pressure. The right inner wall of the fixed tube 13 is slidably connected to a notched tube 19.

[0025] Refer to the figure Figure 2 - Figure 4The outer wall of gear 1 (7) meshes with the outer wall of rack 1 (8). Rack 1 (8) evenly distributes force, reducing stress concentration and extending the service life of components. Excellent wear resistance and fatigue resistance also contribute to improved reliability of the entire transmission system. The right outer wall of the handheld cutter (4) contacts the left outer wall of the rotating inclined tube (9). The outer wall of gear 2 (11) meshes with the outer wall of rack 2 (12). Gear 2 (11) transmission achieves precise transmission ratios and ensures stable power transmission. The right outer wall of the rotating inclined tube (9) contacts the left outer wall of the fixed tube (13). The left outer wall of the stopper (15) contacts the left inner wall of the housing (14). The design of the stopper (15) is generally simple, facilitating manufacturing and maintenance while also reducing production costs. The inner wall of the housing (14) is slidably connected to the right outer wall of the fixed tube (13). A spring (16) is fixedly connected to the right outer wall of the stopper (15), while the outer wall of the ball (18) is slidably connected to the right inner wall of the fixed tube (13). The sphere 18 has less rolling resistance than objects of other shapes when rolling, which makes the sphere 18 very useful in transportation and mechanical design. The outer wall of the sphere 18 is slidably connected to the inner wall of the slotted tube 19 , and the outer wall of the sphere 18 is slidably connected to the right inner wall of the housing 14 .

[0026] Working principle: The output volume can be adjusted by rotating the regulating valve 2, and the medium will be transmitted from the hose 3 to the handheld cutter 4. When the angle adjustment is required, start the motor 6. The operation of the motor 6 will drive the gear 7 to rotate, and the rotation of the gear 7 will drive the rack 8 to rotate. The rotation of the rack 8 will drive the rotating inclined tube 9 to rotate. Start the motor 2 10. The rotation of the motor 2 10 will drive the gear 2 11 to rotate. The rotation of the gear 2 11 will then drive the rack 2 12 to rotate. The rotation of the rack 2 12 will drive the fixed tube 13 to rotate, thereby realizing the effect of angle adjustment, being able to quickly adjust the cutting angle, reducing the time for on-site repositioning and preparation, speeding up the rescue process, reducing the time spent on rescue personnel, and eliminating the need to use other tools to assist in completing the cutting task, so that the equipment can handle more diverse rescue tasks.

[0027] When the nozzle needs to be disassembled, the sleeve 14 is pulled. The sliding of the sleeve 14 will compress the spring 16 to contract. The contraction of the sleeve 14 will cause the top of the sphere 18 to have no force applied. At this time, the notched tube 19 is pulled. The pulling of the notched tube 19 will cause the notch of the notched tube 19 to press against the sphere 18, so that the sphere 18 rises upward and the notched tube 19 can be taken out to complete the disassembly. The quick disassembly design allows the operator to quickly replace or repair the nozzle, which can greatly reduce the maintenance time of the equipment, especially in emergency rescue or continuous production environments, and can resume cutting operations more quickly.
