[0027] The working principle of the manual clutch device of the reduction motor provided by the present invention is as follows: 1. The linkage between the reduction motor and the reciprocating screw 4 Start the reduction motor: the reduction motor body 2 is fixed to one end of the bracket 1 and starts running; The reciprocating screw rod 4 rotates: the output end of the reduction motor body 2 drives the reciprocating screw rod 4 to rotate; 2. Pumping mechanism of piston 13 and connecting tank 3 The piston 13 reciprocates: the rotation of the reciprocating screw 4 drives the L-shaped driving rod 14 and the piston 13 to reciprocate inside the connecting tank 3; Pumping process: When the piston 13 moves in one direction, the space of an air chamber inside the connecting tank 3 increases, and air is sucked in through the air inlet hole 15. At this time, the sealing spring 16 opens due to the change in air pressure, allowing air to enter; When the piston 13 moves in the opposite direction, the space of the pumping chamber is reduced, and the sealing spring 16 is pressed against the air inlet 15 due to the increase of air pressure to prevent air backflow, and the gas in the pumping chamber is compressed at the same time; Gas output: The compressed gas passes through the pipeline, the through hole 10, the air guide seat 11 and the ventilation hole 9, and blows directly to the mounting groove 17 of the driven clutch plate 7; 3. Operation of the clutch plate and guide plate 8 Clutch plate cooling: The directly blown gas cools the mounting groove 17 of the driven clutch plate 7, part of the gas blows the active clutch plate 5 through the expansion groove 18 and the chamfer, and the other part of the gas is dispersed through the guide plate 8 to achieve multi-angle cooling; Deformation of guide piece 8: The lever 29 is manually pushed, and the lever 29 squeezes the lever 26 through the lever ring 28, and the lever 26 overcomes the resistance of the resistance spring 27, driving the push rod 22 to move; The active rack 23 on the push rod 22 drives the driven rack 24 through the transmission gear 25, thereby rotating the spread rack 21, and the spread rack 21 meshes with the sector gear 19, driving the guide piece 8 to change from a cylindrical shape to a conical shape; 4. Braking and releasing of connecting shaft 6 Braking process: The lever 29 continues to move, driving the extrusion plate 32 to move through the pull rod 34, and the slope 33 of the extrusion plate 32 squeezes the plurality of clamping blocks 31, so that the clamping blocks 31 gather together and tightly hold the connecting shaft 6, thereby forming a braking effect; As the pull rod 34 continues to move, the extrusion plate 32 stops moving, compressing the buffer spring 35; Release process: When the lever 29 stops moving and resets, the extrusion plate 32 is reset under the action of the buffer spring 35, and the plurality of clamping blocks 31 move away from each other under the action of the annular spring sheet 30, thereby releasing the connecting shaft 6; 5. Safety Locking Mechanism When the lever 29 is moved to a certain position, the latch 38 can be inserted to prevent the lever 29 from resetting, thereby ensuring that the connecting shaft 6 is in a stable braking state; 6. Other details Engine model 12: Although the engine model 12 is connected to the connecting shaft 6 through a spline transmission, during the working process of the clutch device, the engine model 12 does not directly participate in the clutch operation and is used for simulation purposes; The retaining ring 36 and the compression spring 37: The compression spring 37 between the retaining ring 36 and the bracket 1 ensures that the connecting shaft 6 maintains a certain position stability when not subjected to external forces.
