[0052] In combination with Figures 1-3 , referring to Figure 7 , the main function of the turnover pressing and cutting mechanism is to press the hose 20 to prevent the hose 20 from arching during cutting, and to cut the hose 20 vertically. The turnover pressing and cutting mechanism comprises a rotating shaft 29, a cover plate 39, a blade fixing block 40, a torsion spring 31, a medical blade 41, a handle fixing block 42, a handle 4, a reset torsion spring 38, a rotating support seat 28, a connecting block 32, a rotating bearing 27, a pressing block 37, a turnover limiting block 30, a positioning pin 26, a guide shaft 33, a linear bearing 34, and a limiting sleeve 35.

[0053] The cover plate 39 is rotatably mounted on the panel 13 through the rotating shaft 29. Specifically, the front and rear rotating support seats 28 are mounted on the panel 13 through the vertically arranged positioning pins 26 and are located on the side of the fixed carrier plate 19 away from the movable carrier plate 18. The bottom of the cover plate 39 is provided with the front and rear connecting blocks 32, the rotating shaft 29 penetrates the connecting blocks 32 and is mounted on the rotating support seats 28 through the rotating bearing 27. The rotating shaft 29 extends along the first direction and is located on the side of the fixed carrier plate 19 away from the movable carrier plate 18. The reset torsion spring 38 is arranged on the rotating shaft 29 to provide the torsion force for resetting the cover plate 39. The overturning limiting block 30 is fixed on the panel 13 and is located on the side of the rotating support seat 28 away from the fixed carrier plate 19. The side of the overturning limiting block 30 facing the cover plate 39 is provided with an inclined surface. When the cover plate 39 is overturned upward, it cannot continue to be overturned after colliding with the inclined surface. Therefore, the overturning limiting block 30 can limit the angle of the cover plate 39 when it is opened.

[0054] The medical blade 41 is arranged on the end of the cover plate 39 close to the hose winding belt 47. Specifically, the rear end of the cover plate 39 is mounted on the blade fixing block 40 through screws or the like. The blade fixing block 40 is perpendicular to the cover plate 39. The medical blade 41 is embedded in the blade fixing block 40. In order to ensure safety, the medical blade 41 is as little exposed as possible. The blade fixing block 40 is provided with an opening matching the shape of the hose. The medical blade 41 is completely embedded in the blade fixing block 40. The medical blade 41 is only exposed in the opening of the blade fixing block 40 for cutting.

[0055] The handle fixing block 42 is fixed on the top of the cover plate 39 through a pin or a screw or the like and is close to the side of the cover plate 39 opposite to the rotating shaft 29. The handle 43 is connected to the handle fixing block 42. The handle 43 extends along the width direction of the cover plate 39. The operator can operate the handle 43 downward when cutting the hose.

[0056] The pressing block 37 is floatingly connected to the bottom center of the cover plate 39 through the cooperation of the guide shaft 33, the linear bearing 34 and the limiting sleeve 35. The purpose of the floating connection is to buffer and to tightly press the hoses with different thicknesses. Specifically, the linear bearing 34 is vertically embedded in the cover plate 39. The guide shaft 33 vertically penetrates the pressing block 37 and the linear bearing 34. The linear bearing 34 is externally provided with the limiting sleeve 35 from the exposed part of the top of the cover plate 39. In this way, the pressing block 37 can slightly shake and will not be deviated. The force is uniformly applied.

[0057] The length of the pressing block 37 is consistent with the length of the cover plate 39, and the width of the pressing block 37 is equivalent to the distance between the top step of the moving carrier plate 18 and the top step of the fixed carrier plate 19. The bottom of the cover plate 39 is provided with a guide column 36, and the panel 13 is fixed with a guide bushing 25 located on the side of the moving carrier plate 18 away from the fixed carrier plate 19. When the cover plate 39 is flipped to the direction close to the fixed carrier plate 19 and the guide column 36 is inserted into the guide bushing 25, the pressing block 37 falls onto the bottom step of the moving carrier plate 18 and the bottom step of the fixed carrier plate 19 and is located between the top step of the moving carrier plate 18 and the top step of the fixed carrier plate 19. The bottom of the pressing block 37 is in contact with the hose 20 to press the hose 20, thereby straightening the hose 20 and preventing the hose from shaking and bending to cause poor consistency of the cutting size of the hose 20. At the same time, the medical blade 41 vertically cuts and cuts the hose 20, and the return torsional spring 38 provides torsional force to flip the cover plate 39 upward to the open state.

[0058] The process of cutting the hose 20 in this embodiment is as follows: the head of the medical hose 20 is pulled out from the hose roll 47, passes through the gap between the hose pressing seat 24 and the hose pressing bearing 22, and is tightly fixed to the hose fixing head of the hose fixing block 11 until the medical hose 20 is straightened and tightly fixed to the fixed carrier plate 19. The moving carrier plate 18 is adjusted to move close to the fixed carrier plate 19 along the carrier positioning pin 17 until the medical hose 20 is well positioned and fixed in the horizontal plane, and then the moving carrier plate 18 is locked by a screw. The hand screw 7 on the sliding adjustment mechanism is manually twisted, and under the sliding action of the sliding rail 4 and the sliding block 3, the cutting length of the medical hose 20 is adjusted, and then the hand screw 7 is tightened to prevent the cutting length from deviating due to accidental contact of the hand screw 7 by the sliding adjustment mechanism. The size alignment block 12 is adjusted to align the size alignment pointer 12 with the size scale on the metal scale 16, and the cutting size of the hose is accurately adjusted. Then the handle 43 of the flip pressing and cutting mechanism is pulled, and at this time the flip pressing and cutting mechanism tightly presses the medical hose 20 through the pressing block 37 under the precise cooperation of the guide column 36 and the guide bushing 25, to prevent the medical hose 20 from arching during cutting. When the handle 43 is pressed downward under the inertia of force, the blade 41 vertically cuts the medical hose 20 under the cooperation of the guide shaft 33 and the linear bearing 34 and the floating action of the spring 38, and at the same time the flip pressing and cutting mechanism is quickly reset under the counterforce of the torsional spring 31, thereby realizing the cutting operation of the medical hose 20.

[0059] The embodiments of the present application are described above with reference to the accompanying drawings, but the present application is not limited to the above-described specific embodiments, and the above-described specific embodiments are merely illustrative, but not restrictive, and a person of ordinary skill in the art can make many forms under the inspiration of the present application without departing from the purpose of the present application and the scope protected by the claims, and these all belong to the protection of the present application.
