6. A method for using a biomass fuel compacting device with an anti-loosening structure according to any one of claims 1 to 5, characterized in that: The steps include: Step 1: Start the motor (4), the output end of the motor (4) drives the rotating shaft (6) to rotate, the rotating shaft (6) drives the crushing rod (3) to disperse the biomass fuel inside the box (1), and allows the biomass fuel to enter between the discharge port (22) and the extrusion frame (12), and at the same time, the rotating shaft (6) drives the rotating disk (16) to rotate, the rotating disk (16) drives the rotating rod (9) to rotate, under the action of the hinge, the rotating rod (9) drives the connecting rod (17) to swing, and the connecting rod (17) drives the push rod (15) to continuously extend and retract; Step 2: The push rod (15) pushes the fixed plate (13) to move toward the discharge port (22), the fixed plate (13) pushes the spring (20) to move, the spring (20) pushes the extrusion frame (12) to move toward the discharge port (22), the extrusion frame (12) pushes the biomass fuel into the conical guide cover (11), and then the extrusion frame (12) is blocked by the conical guide cover (11), the fixed plate (13) continues to move toward the conical guide cover (11), and compresses the spring (20), the fixed plate (13) pushes the compacting rod (21) to move into the discharge pipe (10), so that the compacting rod (21) compacts the biomass fuel in the discharge pipe (10); Step 3: The pressure sensor (28) monitors the pressure of the biomass fuel on the side wall of the discharge pipe (10) in real time. When the pressure measured by the pressure sensor (28) is greater than the internal set value of the pressure sensor (28), the pressure sensor (28) sends a signal to the controller (24). The controller (24) controls the first cylinder (25) and the second cylinder (32) to start. The output end of the first cylinder (25) drives the blocking plate (27) to move upward to open the output port of the discharge pipe (10). Then, the output end of the second cylinder (32) pushes the slide plate (26) to slide along the inner wall of the second slide groove (30). The slide plate (26) drives the moving cylinder (29) to move. The moving cylinder (29) pushes the compacted biomass fuel out of the discharge pipe (10). Then, the first cylinder (25) and the second cylinder (32) are started to reset the blocking plate (27) and the moving cylinder (29), so as to facilitate the compaction of the biomass fuel again.
