[0025] Specifically, a limiting groove 35 is formed on the surface of the guide sleeve 36. The limiting groove 35 is located on both sides of the extractor 1. The limiting groove 35 can cooperate with the guide sleeve 36 to achieve the purpose of guiding the limiting block 31.
[0026] Specifically, a limiting block 31 is fixedly connected to one side of the slide bar 32, and the limiting block 31 is slidably connected to the inside of the limiting groove 35.
[0027] In this embodiment, the limiting block 31 can cooperate with the slider 32 to achieve the purpose of limiting the slider 32.
[0028] In this embodiment: a replacement device 4 is provided at one end of the slide bar 32. The replacement device 4 includes a tray 44. The tray 44 is fixedly connected to one end of the slide bar 32. The tray 44 is slidably connected to the surface of the needle 2. The tray 44 can cooperate with the slide bar 32 to achieve the purpose of supporting the tray 44.
[0029] Specifically, multiple limiting rods 43 are fixedly connected to the surface of the tray 44, the limiting rods 43 are located on one side of the extractor 1, and guide channels 46 are fixedly connected to the surface of the tray 44.
[0030] In this embodiment, the limiting rod 43 can cooperate with the tray 44 to support the limiting rod 43.
[0031] Specifically, one end of the sleeve 37 is fixedly connected to a placement plate 42, which is placed on the surface of the tray 44. The surface of the placement plate 42 has multiple sleeve holes 41, which are fitted onto the surface of the limiting rod 43.

The limiting block 31 slides inside the limiting groove 35, and the slide bar 32 slides inside the guide sleeve 36. The slide bar 32 pushes the sleeve 37. When the sleeve 37 is in close contact with the patient's skin, the trumpet-shaped sleeve 37 can open the patient's skin outward and tighten the patient's skin. The worker controls the discharge device, which adjusts the needle 2 to pierce the patient's body. By setting up the pressing device 3, the skin can be effectively tightened. The needle 2 is tightened around the patient's skin, preventing inaccurate positioning during puncture and reducing damage to the patient's skin tissue. Furthermore, the replacement device 4 allows the worker to rotate the adjusting rod 45 after extraction. The adjusting rod 45, via a thread, drives the slider 47, which slides inside the guide channel 46, disengaging from the placement tray 42. The worker then removes the sleeve 37, which in turn moves the placement tray 42 away from the limiting rod 43. The replacement device 4 effectively facilitates the replacement of the sleeve 37, preventing cross-infection of the patient by bacteria on the sleeve 37 and thus improving the hygiene of the discharge device.
