Description

Technical Field

[0001] This application belongs to the field of Y-type puncture needle technology, and more specifically, relates to an anti-reverse valve incision device in a Y-type puncture needle. Background Technology

[0002] Y-type puncture needles are single-use hospital products primarily used for puncturing blood vessels and guiding guidewires into the bloodstream. One end of the Y-type puncture needle inserts the guidewire, while the other end connects to a syringe. During clinical use, after the Y-type puncture needle enters the blood vessel, blood may seep out. A reverse flow valve is a widely used medical consumable in the medical field, primarily used in Y-type puncture needles, to prevent blood backflow. The reverse flow valve is typically made of silicone, is circular in shape, and has an opening in the center with a film inside the opening. When backflow occurs, the film seals the opening, preventing blood backflow and ensuring that the medication flows only on one side, thus guaranteeing the safety and effectiveness of the infusion.

[0003] Currently, the opening in the middle of the anti-reverse valve is usually cut manually, which results in low cutting precision and low efficiency. Summary of the Invention

[0004] The purpose of this application is to provide an anti-reverse valve cutting device to solve the technical problems of low cutting accuracy and low efficiency caused by manually cutting the opening of the anti-reverse valve in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A backflow preventer valve cutting device is provided for cutting the backflow preventer valve. The backflow preventer valve cutting device includes a positioning component, a horizontal moving mechanism, a cutting component, and a vertical moving mechanism. The cutting component is installed at the output end of the vertical moving mechanism, and the positioning component is installed at the output end of the horizontal moving mechanism. The positioning component is used to position the backflow preventer valve. The horizontal moving mechanism is used to drive the positioning component to move horizontally to directly below the cutting component. The vertical moving mechanism is used to drive the cutting component to descend to cut the backflow preventer valve.

[0006] In one embodiment, the anti-reverse valve cutting device further includes a starting valve, a first sequence valve, and a second sequence valve. The first sequence valve is pneumatically connected to the horizontal moving mechanism, and the second sequence valve is pneumatically connected to the vertical moving mechanism. A first delay valve for delaying the start of the second sequence valve is connected between the starting valve and the first sequence valve, and a second delay valve for delaying the reset of the first sequence valve is connected between the starting valve and the second sequence valve.

[0007] In one embodiment, the anti-reverse valve cutting device further includes a first start button and a second start button, which are connected in series and then electrically connected to the start valve to start the start valve.

[0008] In one embodiment, the positioning assembly includes a mounting base mounted on the horizontal moving mechanism and a plurality of positioning pins disposed on the mounting base, each positioning pin being used to position one of the anti-reverse valves; the cutting assembly includes a plurality of blades, each blade corresponding to one of the positioning pins.

[0009] In one embodiment, the mounting base is provided with a needle seat, and the needle seat has a plurality of vertically penetrating needle holes. Each positioning needle is respectively inserted into each of the needle holes, the bottom end of the positioning needle abuts against the mounting base, and the top end of the positioning needle is used to sleeve the anti-reverse valve.

[0010] In one embodiment, the mounting base is provided with a material-receiving plate, the material-receiving plate having a plurality of through holes, the tip of the positioning pin passing through the through holes and extending out of the through holes to engage the anti-reverse valve; the material-receiving plate is used to support each of the anti-reverse valves and to move upward relative to the mounting base to remove each of the anti-reverse valves.

[0011] In one embodiment, a mounting groove is formed on the mounting base, the material picker plate is received in the mounting groove, the mounting groove has limiting surfaces spaced apart along a first direction for guiding the material picker plate to move up and down; at least one end of the material picker plate extends out of the mounting groove along a second direction.

[0012] In one embodiment, the cutter assembly includes a cutter, the cutter including a connecting piece mounted on the vertical moving mechanism and a plurality of blades spaced apart on the connecting piece, each blade being integrally connected to the connecting piece.

[0013] In one embodiment, the blade has a tip at one end away from the connecting piece, and the tip is formed by a triangular face extending straight along a second direction.

[0014] In one embodiment, the cutter assembly further includes a cutter holder and a pressure plate. The cutter holder is mounted on the output end of the vertical moving mechanism, the pressure plate is mounted on the cutter holder, and the cutter is locked between the cutter holder and the pressure plate.

[0015] The beneficial effects of the anti-backflow valve cutting device provided in this application are as follows: The anti-backflow valve cutting device provided in this application, through the arrangement of a positioning component, a horizontal moving mechanism, a cutting component, and a vertical moving mechanism, can, on the one hand, drive the positioning component to move via the horizontal moving mechanism, allowing the positioning component and the anti-backflow valve to move directly below the cutting component. On the other hand, the vertical moving mechanism drives the cutting component vertically downwards to perform a cutting operation on the anti-backflow valve. This vertical cutting operation results in higher accuracy, depth, and verticality of the opening. Simultaneously, the horizontal moving mechanism can move the positioning component away from directly below the cutting component, facilitating the installation of the anti-backflow valve and ensuring operational safety, preventing accidental injury. Furthermore, this application achieves automatic cutting operation of the anti-backflow valve through the joint use of the positioning component, horizontal moving mechanism, cutting component, and vertical moving mechanism, improving the cutting accuracy and efficiency of the anti-backflow valve and saving labor costs.

Detailed Implementation

[0028] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0029] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0030] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] Please see Figures 1 to 5 The backflow prevention valve incision device provided in the embodiments of this application will now be described. This backflow prevention valve incision device is used to perform an incision operation on the backflow prevention valve 2000, specifically to perform an incision operation on the backflow prevention valve 2000 on the Y-shaped puncture needle, so as to form an opening 2100 on the backflow prevention valve 2000.

[0033] The anti-backflow valve cutting device includes a positioning component 300, a horizontal moving mechanism 200, a cutting component 500, and a vertical moving mechanism 400. The cutting component 500 is installed at the output end of the vertical moving mechanism 400, and the positioning component 300 is installed at the output end of the horizontal moving mechanism 200. The positioning component 300 is used to position the anti-backflow valve 2000. The horizontal moving mechanism 200 is used to drive the positioning component 300 to move horizontally to directly below the cutting component 500. The vertical moving mechanism 400 is used to drive the cutting component 500 to descend in order to cut the anti-backflow valve 2000.

[0034] The positioning component 300 has a first position and a second position. When the positioning component 300 is in the first position, it can avoid the cutter component 500, that is, the positioning component 300 is not below the cutter component 500. This makes it easier for the operator to install the anti-backflow valve 2000 on the positioning component 300 and avoid being accidentally injured by the cutter component 500. When the positioning component 300 is in the second position, the positioning component 300 is located directly below the cutter component 500, so that the anti-backflow valve 2000 is located directly below the cutter component 500, which makes it easier for the cutter component 500 to cut the anti-backflow valve 2000.

[0035] The cutter assembly 500 has an initial position and an end position. When the cutter assembly 500 is in the initial position, it is at the top and avoids the positioning assembly 300, which facilitates the horizontal movement of the positioning assembly 300 and the installation of the anti-backflow valve 2000. When the cutter assembly 500 is in the end position, the cutter assembly 500 performs a cutting operation on the anti-backflow valve 2000.

[0036] The anti-backflow valve cutting device in this embodiment, through the arrangement of a positioning component 300, a horizontal moving mechanism 200, a cutting component 500, and a vertical moving mechanism 400, allows the positioning component 300 to move via the horizontal moving mechanism 200, enabling it and the anti-backflow valve 2000 to move directly below the cutting component 500. The vertical moving mechanism 400 then drives the cutting component 500 vertically downwards to cut the anti-backflow valve 2000. This vertical cutting operation results in higher accuracy, depth, and verticality of the opening 2100. Simultaneously, the horizontal moving mechanism 200 allows the positioning component 300 to avoid being directly below the cutting component 500, facilitating the installation of the anti-backflow valve 2000 while ensuring operational safety and preventing accidental injury. In addition, this application achieves automatic cutting operation of the anti-backflow valve 2000 through the positioning component 300, the horizontal moving mechanism 200, the cutting component 500, and the vertical moving mechanism 400, thereby improving the cutting accuracy and efficiency of the anti-backflow valve 2000 and saving labor costs.

[0037] In one embodiment, see Figure 1 and Figure 9 The anti-reverse valve cutting device also includes a solenoid valve assembly 700; the solenoid valve assembly 700 includes a starting valve 730, a first sequence valve 710 and a second sequence valve 720, the first sequence valve 710 is pneumatically connected to the horizontal moving mechanism 200, the second sequence valve 720 is pneumatically connected to the vertical moving mechanism 400, a first delay valve 740 for delaying the starting of the second sequence valve 720 is connected between the starting valve 730 and the second sequence valve 720, and a second delay valve 750 for delaying the reset of the first sequence valve 710 is connected between the starting valve 730 and the first sequence valve 710. When the starting valve 730 is activated, due to the setting of the first delay valve 740, the first sequence valve 710 first connects the horizontal moving mechanism 200 and the starting valve 730. The horizontal moving mechanism 200 drives the positioning component 300 and the anti-reverse valve 2000 to move together to directly below the cutter assembly 500. Then, the second sequence valve 720 connects the vertical moving mechanism 400 and the starting valve 730. The vertical moving mechanism 400 drives the cutter assembly 500 to descend to perform a cutting operation on the anti-reverse valve 2000. After the cutting operation is completed, the starting valve 730 is stopped. Due to the setting of the second delay valve 750, the vertical moving mechanism 400 first drives the cutter assembly 500 to rise and reset, and then the horizontal moving mechanism 200 drives the positioning component 300 and the anti-reverse valve 2000 to reset horizontally. In this embodiment, the setting of the starting valve 730, the first sequence valve 710, and the second sequence valve 720 enables the horizontal moving mechanism 200 and the vertical moving mechanism 400 to move in tandem, improving the effect.

[0038] In one embodiment, both the first delay valve 740 and the second delay valve 750 are one-way throttle valves. The first delay valve 740 is a one-way throttle valve in the direction from the start valve 730 to the second sequence valve 720, and the second delay valve 750 is a one-way throttle valve in the direction from the first sequence valve 710 to the start valve 730. In this embodiment, the sequential activation of the first sequence valve 710 and the second sequence valve 720 is delayed by throttling. It is understood that in other embodiments of this application, the first delay valve 740 and the second delay valve 750 may also be on / off valves, such as directly opening or directly closing the channel; this is not a unique limitation.

[0039] In one embodiment, see Figure 1 The anti-reverse valve cutting device also includes a first start button 800 and a second start button 900. The first start button 800 and the second start button 900 are connected in series and electrically connected to the start valve 730 for starting the start valve 730. In this embodiment, by connecting the first start button 800 and the second start button 900 in series, both the first start button 800 and the second start button 900 need to be pressed simultaneously to start the start valve 730, thereby reducing the risk of accidental injury to workers due to accidentally pressing the start button.

[0040] For details, please refer to Figure 1 The first start button 800 and the second start button 900 are respectively located on opposite sides of the anti-reverse valve cut-off device, meaning they are spaced a considerable distance apart to prevent accidental activation by personnel. However, the distance between the first start button 800 and the second start button 900 should not be too large, ensuring that a single operator can press both buttons simultaneously.

[0041] Taking the horizontal moving mechanism 200 moving in the front and back direction as an example, the first start button 800 and the second start button 900 are respectively located on the front side of the anti-reverse valve cutting device and close to the left and right edges, which facilitates operation by the staff.

[0042] In one embodiment, see Figure 4The positioning component 300 includes a mounting base 310 and multiple positioning pins 320. The mounting base 310 is mounted on the horizontal moving mechanism 200, and the multiple positioning pins 320 are mounted on the mounting base 310. Each positioning pin 320 is used to position one anti-backflow valve 2000. The cutting component 500 includes multiple blades 511, each blade 511 corresponding to one of the positioning pins 320. This arrangement allows multiple anti-backflow valves 2000 to be installed on the mounting base 310 simultaneously. Specifically, the anti-backflow valve 2000 is fitted onto the top of the positioning pin 320, and the multiple blades 511 are used to cut multiple anti-backflow valves 2000. In other words, this anti-backflow valve cutting device can be used to cut multiple anti-backflow valves 2000 simultaneously, improving the cutting efficiency of the anti-backflow valves 2000 and reducing labor costs.

[0043] In one embodiment, see Figure 1 and Figure 2 The horizontal moving mechanism 200 can drive the mounting base 310 to move along the first direction X, and the positioning pins 320 are arranged at intervals along the second direction Y. The first direction X and the second direction Y are perpendicular to each other and both are perpendicular to the vertical direction. Specifically, the first direction X is the front-to-back direction, and the second direction Y is the left-to-right direction. The above arrangement makes the entire anti-reverse valve cutting device compact and reduces the space occupied along the first direction X. Alternatively, in other embodiments of this application, the horizontal moving mechanism 200 can also drive the mounting base 310 to move along the first direction X, and the positioning pins 320 can also be arranged at intervals along the first direction X. This is not a unique limitation.

[0044] In one embodiment, see Figure 5 A notch 321 is formed at the center of the tip of the positioning pin 320. Specifically, since the blade 511 needs to cut the cap of the anti-reverse valve 2000, the blade 511 needs to extend downward into the positioning pin 320. The notch 321 is designed to avoid interference and collision between the blade 511 and the positioning pin 320, thus preventing the blade 511 from affecting its service life.

[0045] Please see Figure 4 Each anti-reverse valve 2000 is distributed sequentially at intervals along the second direction Y on the mounting base 310. The opening 2100 on the anti-reverse valve 2000 extends along the second direction Y. The notch 321 on the positioning pin 320 penetrates through the opposite sides of the positioning pin 320 along the second direction Y. This makes the top of the positioning pin 320 elastic, so that the anti-reverse valve 2000 can be easily fitted onto the top of the positioning pin 320, and achieves an interference fit between the anti-reverse valve 2000 and the positioning pin 320.

[0046] In one embodiment, see Figure 2 , Figure 4 and Figure 5The mounting base 310 is provided with a needle seat 330, on which multiple vertically penetrating needle holes are formed. Each positioning needle 320 is inserted into a needle hole, with the bottom end of the positioning needle 320 abutting against the mounting base 310 and the top end of the positioning needle 320 used to fit the anti-backflow valve 2000. Since the positioning needle 320 has a small diameter and a long length, it would be difficult to process directly by forming blind holes for mounting and limiting the positioning needle 320 on the mounting base 310. In this embodiment, a needle seat 330 is additionally provided on the mounting base 310, with vertically penetrating needle holes formed on it. The bottom end of the positioning needle 320 abuts against the mounting base 310 to form an axial limit for the positioning needle 320. Thus, only the needle holes that are easier to process need to be formed on the needle seat 330, reducing the processing difficulty of the needle holes.

[0047] For details, please refer to Figure 4 and Figure 5 The mounting base 310 has a receiving groove 311 at its center, and the needle holder 330 is housed in the receiving groove 311. The needle holder 330 is locked and fixed to the mounting base 310 by a first fastener. With this configuration, if the needle holder 330 or the positioning needle 320 is damaged, the needle holder 330 and the positioning needle 320 can be disassembled and replaced without replacing the entire mounting base 310.

[0048] Please see Figure 5 Each positioning pin 320 has a mounting hole 331 for each positioning pin 330. A positioning element (not shown) is installed in the mounting hole 331. The positioning element is used to abut against the surface of the positioning pin 320 to limit the positioning pin 320. Specifically, the positioning element can be a pin or a glass ball screw.

[0049] In one embodiment, see Figures 3 to 5 The mounting base 310 is provided with a material taking plate 340, which has multiple through holes. The top end of the positioning pin 320 passes through the through holes and extends out to engage with the anti-backflow valve 2000. The material taking plate 340 is used to support each anti-backflow valve 2000 and to move upward relative to the mounting base 310 to remove each anti-backflow valve 2000.

[0050] During installation, first, the material-receiving plate 340 is fitted onto the top of each positioning pin 320, with the top of each positioning pin 320 extending beyond the upper surface of the material-receiving plate 340. Then, each anti-backflow valve 2000 is fitted onto the top of each positioning pin 320, with each anti-backflow valve 2000 supported on the material-receiving plate 340. After the cutter assembly 500 completes the cutting operation on each anti-backflow valve 2000, the material-receiving plate 340 is pushed upward relative to the mounting base 310, which will disengage each anti-backflow valve 2000 from the positioning pin 320 along with the material-receiving plate 340.

[0051] In this embodiment, because the anti-backflow valve 2000 is made of silicone material and has an interference fit with the positioning pin 320, it is difficult to remove the anti-backflow valve 2000 from the positioning pin 320. However, the material handling plate 340 not only allows the anti-backflow valve 2000 to be easily removed from the positioning pin 320, but also allows multiple anti-backflow valves 2000 to be removed at the same time, simplifying the operation and improving the material handling efficiency of the anti-backflow valve 2000.

[0052] In one embodiment, see Figures 3 to 5 The material taking plate 340 is supported above the needle seat 330. The bottom side of the material taking plate 340 is fitted to the top side of the needle seat 330. The positioning needle 320 is respectively installed through the needle seat 330 and the material taking plate 340. The bottom end of the positioning needle 320 abuts against the bottom wall of the receiving groove 311 of the mounting base 310. The top end of the positioning needle 320 extends beyond the material taking plate 340 for the anti-backflow valve 2000 to be sleeved.

[0053] In one embodiment, see Figure 5 The mounting base 310 has a mounting groove 312, in which the material-taking plate 340 is housed. The mounting groove 312 has a limiting surface 313 spaced along the first direction X for guiding the material-taking plate 340 to move up and down. At least one end of the material-taking plate 340 extends out of the mounting groove 312 along the second direction Y. The limiting surface 313 serves two purposes: firstly, it limits the material-taking plate 340 within the mounting groove 312; secondly, it guides the material-taking plate 340 when it is moved upwards, ensuring stable material taking. Furthermore, the design of at least one end of the material-taking plate 340 extending out of the mounting groove 312 along the second direction Y allows the end of the material-taking plate 340 to be manually pushed from outside the mounting base 310, thereby disengaging the material-taking plate 340 and each anti-reverse valve 2000 from the positioning pin 320, making operation convenient and labor-saving.

[0054] Optionally, please refer to Figure 2 The receiving groove 311 extends through the opposite sides of the mounting base 310 along the second direction Y, and the opposite ends of the picking plate 340 extend beyond the mounting groove 312. This arrangement allows the opposite ends of the picking plate 340 to be pushed by both hands during material picking, thereby enabling the picking plate 340 and the anti-backflow valve 2000 to be quickly and smoothly removed from the positioning pin 320.

[0055] In this application, please refer to Figure 4The anti-backflow valve 2000 is manufactured in batches. Therefore, multiple anti-backflow valves 2000 are connected together during the cutting operation. Adjacent anti-backflow valves 2000 are connected by a connecting ring 3000. Since the anti-backflow valves 2000 are connected in a row along the second direction Y, and the positioning pins 320 are arranged at intervals along the second direction Y, and the opening 2100 of the anti-backflow valve 2000 extends in the second direction Y, when a row of anti-backflow valves 2000 connected in the second direction Y is fitted onto the positioning pins 320, the installation direction of each anti-backflow valve 2000 is exactly correct. That is, there is no need to set a positioning structure on the mounting base 310 to position the anti-backflow valve 2000, which can ensure the accurate positioning direction of the anti-backflow valve 2000.

[0056] In one embodiment, see Figure 1 and Figure 2 The anti-reverse valve cutting device also includes a base 100, a horizontal moving mechanism 200 mounted on the base 100, and a vertical moving mechanism 400 mounted on the base 100 via a bracket 600.

[0057] In one embodiment, see Figure 2 The horizontal moving mechanism 200 is a first cylinder, which includes a first body 210 and a first output end 220. The first output end 220 can move relative to the first body 210 along a first direction X. The first body 210 is mounted on the base 100, and the mounting seat 310 is mounted on the first output end 220. The first body 210 is located directly below the cutter assembly 500. The first output end 220 can move away from the first body 210 to avoid being directly below the cutter assembly 500, and the first output end 220 can also move towards the first body 210 to be directly below the cutter assembly 500. In this embodiment, by arranging the first body 210 and the first output end 220 in the above-mentioned positions, the space occupied by the entire horizontal moving mechanism 200 along the first direction X can be reduced. Understandably, in other embodiments of this application, the positions of the first body 210 and the first output terminal 220 may be interchanged. In this case, when the first output terminal 220 moves away from the first body 210, it will move directly below the cutter assembly 500, while when the first output terminal 220 moves towards the first body 210, it will move away from the cutter assembly 500. This is not a unique limitation.

[0058] In one embodiment, see Figures 6 to 8The cutting assembly 500 includes a cutting blade 510, which includes a connecting piece 512 mounted on the output end of the vertical moving mechanism 400 and a plurality of blades 511 spaced apart on the connecting piece 512. The connecting piece 512 is integrally connected to each blade 511. In this embodiment, the blades 511 are connected as a whole by the connecting piece 512, thereby simplifying the manufacturing process of each cutting blade 510 and reducing the assembly cost of each cutting blade 510.

[0059] In one embodiment, see Figure 8 The connecting piece 512 is an elongated piece extending along the second direction Y. Each blade 511 is sequentially and spaced apart below the connecting piece 512 along the second direction Y, and the blades 511 at both ends are respectively connected to the two ends of the connecting piece 512.

[0060] In one embodiment, see Figure 8 The blade 511 has a pointed tip 5111 at the end opposite to the connecting piece 512. The pointed tip 5111 is formed by a triangular facet extending along the second direction Y. The pointed tip 5111 makes the blade 511 sufficiently sharp to cut the anti-reverse valve 2000. The pointed tip 5111 is formed by a triangular facet extending along the second direction Y, so that the pointed tip 5111 is evenly distributed along the second direction Y, thereby making the force exerted by the pointed tip 5111 on the anti-reverse valve 2000 along the second direction Y evenly distributed, and thus making the opening 2100 evenly distributed along the second direction Y.

[0061] In one embodiment, see Figure 6 and Figure 7 The cutter assembly 500 also includes a cutter holder 520 and a pressure plate 530. The cutter holder 520 is installed at the output end of the vertical moving mechanism 400. The cutter 510 abuts against the cutter holder 520 and the pressure plate 530. The pressure plate 530 is locked to the cutter holder 520. That is, the cutter 510 is fixed by the clamping force of the pressure plate 530 and the cutter holder 520, avoiding the need to machine a locking hole on the cutter 510. At the same time, the setting of the pressure plate 530 can make the cutter 510 press smoothly between the cutter holder 520 and the pressure plate 530, and will not deform due to force, thereby ensuring the cutting operation of the cutter 510 on the anti-reverse valve 2000.

[0062] In one embodiment, see Figure 7 The cutter holder 520 has a recessed groove 521 on one side, in which the cutter 510 is housed. The pressure plate 530 is also housed in the groove 521 and presses against the cutter 510. The groove 521 enhances the secure mounting of the cutter 510 and the pressure plate 530 on the cutter holder 520.

[0063] In one embodiment, the pressure plate 530 is locked to the tool holder 520 by a plurality of second fasteners, each of which passes through the gap between adjacent blades 511 to lock the pressure plate 530 and the tool holder 520.

[0064] In one embodiment, see Figure 2 The bracket 600 includes a vertical part 610 and a horizontal part 620. The vertical part 610 is vertically mounted on the base 100. The horizontal part 620 is connected to the top of the vertical part 610. The horizontal part 620 and the base 100 are spaced apart in the vertical direction. The horizontal moving mechanism 200 and the mounting base 310 are located between the horizontal part 620 and the base 100.

[0065] In one embodiment, see Figure 1 and Figure 2 The vertical moving mechanism 400 is a second cylinder, which is mounted on the horizontal part 620, and the mounting base 310 is mounted on the output end of the second cylinder.

[0066] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
