A limiting seat 40 is provided on the top of the base 1. The height of the opening of the limiting seat 40 corresponds to the limiting rod 25. When starting to cut, the limiting rod 25 will move into the limiting seat 40. At this time, the limiting seat 40 can lock the limiting rod 25 to prevent the protective shell 24 from being accidentally opened during the moving process.

[0035] As Figure 10 shown, a groove 32 is formed on the connecting shaft 26. A convex block 33 is provided at the connection between the protective shell 24 and the connecting shaft 26. The convex block 33 fits with the groove 32. The groove 32 and the convex block 33 can limit the rotation angle of the protective shell 24.

[0036] As Figure 4As shown in the figure, it further includes a second threaded rod 15, a nut plate 151 and a turntable 16. The support frame 2 includes a fixed frame 201 and a movable frame 202. The top of the base 1 is provided with a fixed frame 201. The movable frame 202 is slidably connected inside the fixed frame 201. The bottom of the fixed frame 201 is provided with a nut plate 151. The second threaded rod 15 is threadedly connected inside the nut plate 151. The bottom of the movable frame 202 is provided with a shaft seat 42. The shaft seat 42 is sleeved outside the second threaded rod 15. The left side of the second threaded rod 15 is provided with a turntable 16. When it is necessary to adapt to pipes of different lengths, the turntable 16 can be rotated to drive the second threaded rod 15 to rotate, adjust the position of the movable frame 202, and thus adjust the overall length of the support frame 2.

[0037] As Figure 2 and Figure 3 shown in the figure, it further includes a fixed connection plate 111, a sliding plate 12, a rotary motor 121, a first threaded rod 13 and a guide rod 14. The bottom of the lifting plate 11 is provided with a fixed connection plate 111. The first threaded rod 13 is threadedly connected to the fixed connection plate 111. The sliding plate 12 is slidably connected to the lifting plate 11. The sliding plate 12 is an L-shaped plate, which can block the movement of the pipes located behind the sliding plate 12 when rising. The front side of the sliding plate 12 is provided with a rotary motor 121 and a guide rod 14. The output shaft of the rotary motor 121 is connected to the first threaded rod 13. The guide rod 14 penetrates the fixed connection plate 111. When it is necessary to adapt to pipes of different sizes, the rotary motor 121 can be used to drive the first threaded rod 13 to rotate to adjust the position of the sliding plate 12, thereby adjusting the width of the lifting plate 11 so that the lifting plate 11 can support pipes of different sizes.

[0038] As Figure 12 shown in the figure, it further includes a drawer 36 and a filtering inclined net 35. The drawer 36 is slidably connected to the inside of the collection box 34. The filtering inclined net 35 is provided inside the collection box 34. The mounting plate 23 is located above the collection box 34. After the pipes are cut, the pipes will move along the filtering inclined net 35 to the rear side of the collection box 34, and the debris on the pipes will fall from the filtering inclined net 35 into the drawer 36.

[0039] As Figure 8 shown in the figure, it further includes a rubber pad 41. The rubber pad 41 is provided on the front side of the mounting plate 23. The rubber pad 41 strengthens the fixing effect on the pipes by increasing the friction force.

[0040] In use, place the blood collection chair pipe into the hopper 37. The pipe will fall along the inclined plane of the hopper 37 into the support frame 2, and then slide to the rear of the limit block 3 through the inclined plane of the support frame 2. Place a pipe into the transport frame 5, and then start the electric guide rail 4. The electric guide rail 4 performs a reciprocating motion. First, the electric guide rail 4 drives the push rod 6 to move to the right to transport the pipe to the cutting mechanism, and then moves the push rod 6 back to its original position. When the moving part of the electric guide rail 4 moves to the left, it will drive the connecting piece 7 to move to the left at the same time. The inclined block on the connecting piece 7 will contact the lifting frame 8 and push the lifting frame 8 upward along the inclined plane. When the lifting frame 8 rises, it will lift the next pipe, making it exceed the limit block 3 and move along the inclined plane to the transport frame 5 to prepare for the next round of cutting.

[0041] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention.
