DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 1 , Figure 2 and Figure 6 , the utility model provides an embodiment: 1. A non-destructive shearing device for low-pressure hoses, comprising a support plate 2, a bottom plate 5 is fixedly connected to the bottom of the support plate 2, a top plate 3 is fixedly connected to the top of the support plate 2, an electric rod 4 is fixedly connected to the middle side of the top plate 3, a mounting block 6 is fixedly connected to the output end of the electric rod 4, two sliders 7 are slidably connected to the outside of the mounting block 6, a cutter 22 is fixedly connected to the bottom of the slider 7, a thin shell 15 is fixedly connected to the outside of the slider 7, a paddle rod 19 is slidably connected to the middle side of the inside of the thin shell 15, a baffle 17 is fixedly connected to one side of the outside of the paddle rod 19, a spring 18 is provided on the other side of the outside of the paddle rod 19, a thin shell 2 16 is fixedly connected to the upper part of the thin shell 15, a combination block 20 is provided on the top of the baffle 17, and a clamping assembly is provided on the inner sides of the two support plates 2.

[0035] Specifically, the electric rod 4 is started, and its precision motor starts to run, driving the mounting block 6 to move downward smoothly along the preset track. This action drives the precision cutter 22 on the slider 7 to descend synchronously, ensuring the accuracy and consistency of the cutting process. Before cutting the low-pressure hose, if it is necessary to adjust the position of the cutter 22, the operator will gently push the paddle lever 19 to move the baffle 17 outward. This action will cause the spring 18 to be compressed, so that the assembly block 20 is not subject to resistance, so that it enters the inside of the thin shell 15 and locks the position of the baffle 17 to prevent it from deviating due to operation. After confirming that the paddle lever 19 has been separated from the inside of the mounting block 6, the operator can carefully adjust it to the ideal cutting position, and then gently lift the assembly block 20 upward. With the natural rebound force of the spring 18, the baffle 17 will move inward accordingly, releasing the assembly block 20, so that the paddle lever 19 can smoothly return to the initial position.

[0036] Reference Figure 2 - Figure 4 The clamping assembly includes a connecting plate 1, which is fixedly connected to the outer side of the supporting plate 2, a fixed block 8 is fixedly connected to the outer side of the connecting plate 1, a worm 9 is rotatably connected to the left side of the fixed block 8, a worm wheel 10 is rotatably connected to the middle part of the connecting plate 1, the worm 9 and the worm wheel 10 are meshed, a plurality of connecting blocks 12 are rotatably connected to the outer side of the worm wheel 10, a fixing ring 14 is rotatably connected between the front sides of the plurality of connecting blocks 12, a rotating rod 13 is slidably connected inside the connecting block 12, an end of the rotating rod 13 away from the worm wheel 10 is fixedly connected to a connecting rod 21, and an end of the connecting rod 21 away from the rotating rod 13 is rotatably connected to the outer wall of the connecting plate 1.

[0037] Specifically, in the process of fixing the low-pressure hose, the workers first need to master the operation. They hold the handle, and when the workers twist the handle, the worm 9 inside it rotates clockwise or counterclockwise in the groove of the fixing block 8. This rotation action is not isolated, but is transmitted to the connected worm wheel 10 through a precise meshing mechanism. As the worm wheel 10 rotates, the connecting rod 11 is driven, and the fixing ring 14 is driven to start rotating synchronously, so that the connecting block 12 between the worm wheel 10 and the fixing ring 14 rotates, and then the rotating rod 13 slides and rotates inside the connecting block 12, thereby clamping the low-pressure hose.

[0038] Reference Figure 1 , Figure 4 and Figure 6 A plurality of slots are provided inside the mounting block 6, a paddle rod 19 penetrates the slider 7 and is inserted into the slots, an outer side of the baffle 17 is slidably connected to the inside of the thin shell 15, a plurality of connecting rods 11 are fixedly connected to the outside of the worm gear 10, one end of the connecting rod 11 away from the worm gear 10 is fixedly connected to the inside of the fixing ring 14, an upper side of the assembly block 20 is slidably connected to the inside of the thin shell 2 16, a lower side of the assembly block 20 is slidably connected to the inside of the thin shell 15, one end of the spring 18 is fixedly connected to the middle of the baffle 17, and the other end of the spring 18 is fixedly connected to the inner wall of the thin shell 15, and a handle is fixedly connected to the left side of the worm 9.

[0039] Specifically, there is a card slot inside the mounting block 6, which can flexibly accommodate the paddle rod 19. The paddle rod 19 runs through the slider 7 and is precisely embedded in the card slot, ensuring the accuracy and consistency of the action. The baffle 17 slides inside the thin shell 15. The baffle 17 is also connected to the spring 18. The function of the spring 18 is to balance and buffer. The connecting rod 11 provides a stable and reliable connection. The combination block 20 has a double-layer sliding connection. It can be embedded in the inside of the thin shell 16 and is closely connected to the inside of the thin shell 15. Its up and down movement can limit the inward movement of the baffle 17. The fixed points at both ends of the spring 18 are respectively in the middle of the baffle 17 and the inner wall of the thin shell 15. It is like an elastic fulcrum, which can provide the necessary pressure and ensure the release of tension when needed, thereby ensuring the dynamic balance and smooth operation of the entire system.

[0040] Working principle: When the worker fixes the low-pressure hose, he first twists the handle to drive the worm 9 to rotate in the fixing block 8, and then drives the worm wheel 10 meshing with it to rotate, and then drives the connecting rod 11 to rotate, thereby driving the fixing ring 14 to rotate, so that the connecting block 12 between the worm wheel 10 and the fixing ring 14 rotates, so that the rotating rod 13 slides inside the connecting block 12, and then the rotating rod 13 clamps the low-pressure hose, starts the electric rod 4, so that it pushes the mounting block 6 to move downward, and drives the cutter 22 on the slider 7 to descend together, cutting the low-pressure hose. If the position of the cutter 22 needs to be adjusted, the paddle rod 19 is pushed to move the baffle 17 outward, thereby compressing the spring 18, so that the assembly block 20 slides into the thin shell 15 to prevent the baffle 17 from moving inward. At this time, the paddle rod 19 is separated from the inside of the mounting block 6. At this time, it is only necessary to adjust it to a suitable position and pull the assembly block 20 upward. At this time, the assembly block 20 leaves the thin shell 15, and the baffle 17 moves inward under the push of the elastic force of the spring 18, and then the paddle rod 19 is reinserted into the mounting block 6. At this time, the required low-pressure hose cutting length is adjusted.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
