3. The polytetrafluoroethylene ultrafine fiber production device according to claim 2, characterized in that: The production method of the polytetrafluoroethylene ultrafine fiber production device comprises the following steps: S1. First, the polytetrafluoroethylene raw material is placed into the feed port (3), and the motor (41) drives the screw rod (42) to rotate and extrude the fiber. After the entire extrusion work is completed, the motor (41) is stopped, and the clamping rod (63) is pushed and clamped into the inside of the slide groove (64), and then the handle (86) is pushed, and the handle (86) drives the square block (84) on the surface of the telescopic rod (82) to clamp into the square groove opened in the rotating drum (85); S2, the motor (41) is then started again, the motor (41) drives the screw rod (42) to rotate, and when the screw rod (42) rotates, it drives the extrusion rod (65) at one end to rotate, and when the extrusion rod (65) rotates, it just squeezes the clamping rod (63) that is stuck in the inside of the slide groove (64), and the clamping rod (63) is squeezed to the upper end of the slide groove (64) and the two temporarily remain relatively still, and when the clamping rod (63) is squeezed, it drives the cross bar (62) to move upward, and the cross bar (62) moves upward When the connecting rod (61) is pulled, the connecting rod (61) is driven to rotate the arc plate (5) fixedly connected thereto relative to the frame (2) through the fan-shaped plate (66). The two arc plates (5) rotate in opposite directions, so that the lower part of the extrusion chamber is opened. When the arc plate (5) rotates, the conical plate (72) movably connected to the other end is driven to rotate and open in the same direction as the arc plate (5), so that the spiral blades on the spiral rod (42) and the extrusion port (7) are easily cleaned. S3. At the same time, when the spiral rod (42) rotates, it is connected to the rotating drum (85) through the transmission belt (43), and the rotating drum (85) rotates on the side of the frame (2), and drives the telescopic rod (82) stuck inside to rotate, and the telescopic rod (82) rotates inside the thread groove (81) and moves forward at the same time, and at the same time, the other end of the telescopic rod (82) slides in the inclined groove (87) opened in the cylinder (83), and squeezes the cylinder (83) through the inclined groove (87); S4, when the cylinder (83) slides into the inside of the frame (2), it drives the connecting rod (96) to slide inside the frame (2), and at the same time squeezes the two rotating rods (92) through the universal shaft (95), and the two rotating rods (92) are rotatably connected to each other, and when squeezed, they form a vertical state; S5, when the rotating rod (92) is squeezed, the slide rail (911) is squeezed at the same time. When the slide rail (911) is squeezed, it slides inside the annular slide groove (98) through the slide rods (99) on both sides. At the same time, when the slide rod (99) slides, the meshing gear (910) is driven to rotate, thereby supporting the entire slide rail (911) to slide upward and slide to the lower end of the spiral rod (42). At the same time, the two U-shaped scrapers (913) on the slider (912) at the upper end of the slide rail (911) are stuck on the spiral blade; S6. When the spiral rod (42) rotates, it drives the U-shaped scraper (913) to move forward through the slider (912). When the slider (912) moves, it drives the push rod (104) on the surface to move. The push rod (104) moves to the side of the spring rod (102) and squeezes the spring rod (102). When the spring rod (102) is squeezed, it drives the cleaning rod (103) to move at the same time. The cleaning rod (103) cleans the discharge hole of the conical cylinder (71).
