The sliding member is slidably connected to the assembly and its sliding direction is parallel to the direction of movement of the load slide. The sliding member is connected to the handle in the syringe so that the sliding of the sliding member can pull or push the handle. The driving assembly is used to drive the sliding member to slide. The support member is connected to the mounting base and is used to connect to a PP bottle. The rotation of the connector allows the needle in the syringe to align with the opening of the PP bottle.
[0005] In one possible implementation, the clamping member is elastic and has an arc-shaped clamping portion for accommodating and clamping the outer jacket.
[0006] In one possible implementation, the clamping member further has an arc-shaped limiting portion for cooperating with the clamping portion to clamp the rolled edge of the outer jacket.
[0007] In one possible implementation, the number of clamping parts is two.
[0008] In one possible implementation, the slider has a first fitting portion and a second fitting portion, which slide and fit against the hand from both sides.
[0009] In one possible implementation, the push-pull fixture for the syringe further includes a slide rail and a slider. The slide rail is disposed along the sliding direction of the slider and is fixedly connected to the assembly. The slider is slidably connected to the slide rail and is fixedly connected to the slider.
[0010] In one possible implementation, the support member is provided with a first notch for the bottle neck of the PP bottle to slide into or out of, and the first notch is provided with a U-shaped limiting groove for the annular protrusion on the bottle neck of the PP bottle to slide into or out of.
[0011] In one possible implementation, the drive assembly includes a power component and a fixing member. The power component is fixed to the assembly and has a piston rod capable of extending and retracting along the sliding direction of the slider.

[0012] In one possible implementation, the first power source assembly further includes a first drive motor. The body of the first drive motor is fixedly connected to the mounting base, and the output shaft of the first drive motor is fixedly connected to the connecting member.
[0013] In one possible implementation, the connector has a circular surface coaxially aligned with its rotation axis. The push-pull fixture for the syringe further includes a docking component, a second drive motor, a converter, and a crank. The docking component is rotatably fitted over the circular surface and is fixedly connected to the support component. The body of the second drive motor is fixedly connected to the mounting base, and the output shaft of the second drive motor is parallel to the output shaft of the first drive motor. The converter has a first connecting portion and a second connecting portion with an axial structure, the first connecting portion and the second connecting portion being parallel, and the first connecting portion being coaxially fixedly connected to the output shaft of the second drive motor. One end of the crank is rotatably fitted over the second connecting portion, and the other end of the crank is rotatably connected to the docking component with its rotation axis parallel to the second connecting portion.
[0014] In this embodiment, the syringe jacket is connected to the clamping member, the syringe handle is connected to the sliding member, and the PP bottle containing sodium chloride injection solution is connected to the support member. Then, the connector in the first power source assembly rotates until the syringe needle is aligned with the opening of the PP bottle.

[0035] Please refer to the following: Figures 1 to 6The present invention provides a push-pull fixture for a syringe. The push-pull fixture for a syringe includes a mounting base 1, a first power source assembly 2, a second power source assembly 3, an assembly 4, a clamping member 5, a sliding member 6, a drive assembly 7, and a support member 8. The first power source assembly 2 is mounted on the mounting base 1 and includes a connecting member 21 capable of rotating about a horizontal axis. The second power source assembly 3 is fixedly mounted on the connecting member 21 and has a load slide 31 capable of reciprocating linear motion, the direction of motion of the load slide 31 being perpendicular to the rotation axis of the connecting member 21. The assembly 4 is fixedly connected to the load slide 31. The clamping member 5 is fixedly connected to the assembly 4 and is used to connect to the outer casing 91 of the syringe 9. The sliding member 6 is slidably connected to the assembly 4, and its sliding direction is parallel to the moving direction of the load slide 31. The sliding member 6 is connected to the handle 92 in the syringe 9, so that the sliding of the sliding member 6 can pull or push the handle 92. The driving assembly 7 is used to drive the sliding member 6 to slide. The support member 8 is connected to the mounting base 1, and the support member 8 is used to connect to the PP bottle 120. The rotation of the connecting member 21 can align the needle 94 in the syringe 9 with the bottle mouth of the PP bottle 120.
[0036] The push-pull fixture for syringes provided by this utility model, compared with the prior art, connects the outer casing 91 of syringe 9 to clamping member 5, connects the handle 92 of syringe 9 to sliding member 6, and connects the PP bottle 120 containing sodium chloride injection solution to support member 8. Then, the connecting member 21 in the first power source assembly 2 rotates until the needle 94 of syringe 9 is aligned with the bottle opening of PP bottle 120. Subsequently, the load slide 31 in the second power source assembly 3 slides, allowing the needle 94 to penetrate into PP bottle 120. Then, the drive assembly 7 drives the sliding member 6 to slide, thereby pulling the handle 92 in syringe 9 and drawing out the sodium chloride injection solution from PP bottle 120. In this way, the problem of medical personnel being potentially injured by the needle 94 on syringe 9 when using syringe 9 to draw out sodium chloride injection solution from PP bottle 120 is avoided.
[0037] In this embodiment, after the PP bottle 120 is connected to the support member 8, the bottle opening of the PP bottle 120 can face the rotation axis of the connector 21. The second power source assembly 3 can be a folding servo actuator, specifically an RM-RLA folding servo actuator.
[0038] In some embodiments, see Figure 2 and Figure 12The clamping member 5 is elastic and has an arc-shaped clamping part 51 for accommodating and clamping the outer jacket 91. When the outer jacket 91 is inserted into the clamping part 51, the clamping part 51 clamps the outer jacket 91 through elastic deformation, thereby connecting the outer jacket 91 to the clamping member 5.
[0039] In some embodiments, see Figure 2 and Figure 12 The clamping member 5 also has an arc-shaped limiting part 52, which cooperates with the clamping part 51 to clamp the rolled edge 911 of the outer casing 91. Thus, during the pushing and pulling of the sliding member 6 and the push handle 92, the limiting part 52 and the clamping part 51 can limit the outer casing 91. When the outer casing 91 is removed from the clamping part 51, the rolled edge 911 also exits from between the clamping part 51 and the limiting part 52. In this embodiment, the limiting part 52 is located between the rolled edge 911 and the push handle 92 and is sleeved on the outside of the core rod 93 in the syringe 9.
[0040] In some embodiments, see Figure 12 The number of clamping parts 51 is two, thereby ensuring the reliability of the connection between the clamping member 5 and the outer jacket 91. The limiting part 52 cooperates with one of the clamping parts 51 to clamp the rolled edge 911.
[0041] In some embodiments, see Figure 2 and Figure 13 The slider 6 has a first fitting portion 61 and a second fitting portion 62, which slide against the handle 92 from both sides. Thus, when the outer sleeve 91 is inserted into the clamping portion 51, the handle 92 simultaneously slides between the first fitting portion 61 and the second fitting portion 62, thereby slidably connecting the handle 92 and the slider 6 together. In this embodiment, the second fitting portion 62 is located between the outer sleeve 91 and the handle 92 and has a second notch 621 for the core rod 93 to pass through.
[0042] In some embodiments, see Figure 2 and Figure 6 The push-pull fixture for the syringe further includes a slide rail 10 and a slider 110. The slide rail 10 is arranged along the sliding direction of the slider 6 and is fixedly connected to the assembly 4. The slider 110 is slidably connected to the slide rail 10 and is fixedly connected to the slider 6. The sliding connection between the slider 6 and the assembly 4 can be achieved through the sliding engagement of the slider 110 and the slide rail 10. In this embodiment, two sets of slide rails 10 and sliders 110 can be provided.
[0043] In some embodiments, see Figure 1 , Figure 3 and Figure 8In the prior art, the PP bottle 120 has an annular protrusion 1201 on its neck. The support member 8 is provided with a first notch 81 for the neck of the PP bottle 120 to slide into or out of the first notch 81. The first notch 81 is provided with a U-shaped limiting groove 82 for the annular protrusion 1201 on the neck of the PP bottle 120 to slide into or out of the first notch 81. When the neck of the PP bottle 120 is slidably inserted into the first notch 81, the annular protrusion 1201 on the neck of the PP bottle 120 simultaneously slides into the U-shaped limiting groove 82, thereby slidably connecting the PP bottle 120 and the support member 8 together. At this time, the body of the PP bottle 120 can be in an inclined state with the neck tilted upward, while the support member 8 is in a state of supporting the PP bottle 120. By limiting the annular protrusion 1201 on the neck of the PP bottle 120 through the U-shaped limiting groove 82, the needle 94 can be smoothly inserted into the PP bottle 120.
[0044] In some embodiments, see Figure 1 , Figure 5 , Figure 6 and Figure 11 The drive assembly 7 includes a power assembly 71 and a fixing member 72. The power assembly 71 is fixedly mounted on the assembly 4 and has a piston rod capable of extending and retracting along the sliding direction of the sliding member 6. The fixing member 72 is fixedly connected to both the piston rod of the power assembly 71 and the sliding member 6. The extension and retraction of the piston rod of the power assembly 71 drives the sliding member 6 to slide via the fixing member 72. In this embodiment, the power assembly 71 can be one of an electric push rod, a pneumatic cylinder, or a hydraulic cylinder.
[0045] In some embodiments, see Figure 1 and Figure 4 The first power source assembly 2 further includes a first drive motor 22. The body of the first drive motor 22 is fixedly connected to the mounting base 1, and the output shaft of the first drive motor 22 is fixedly connected to the connecting member 21. The output shaft of the first drive motor 22 can drive the connecting member 21 to rotate.
[0046] As one way to connect the output shaft of the first drive motor 22 to the connector 21, the connector 21 can be directly and fixedly connected to the output shaft of the first drive motor 22. Alternatively, the connector 21 has a shaft-shaped portion 212, which is fixedly connected to the output shaft of the drive motor via a coupling.
[0047] In some embodiments, see Figure 1 , Figure 4 , Figure 7 , Figure 9 and Figure 10The connector 21 has a circular surface 211 coaxially arranged with the rotation axis of the connector 21. The push-pull fixture for the syringe also includes a docking part 130, a second drive motor 140, a converter 150, and a crank 160. The docking part 130 is rotatably sleeved on the circular surface 211 and is fixedly connected to the support 8. The body of the second drive motor 140 is fixedly connected to the mounting base 1, and the output shaft of the second drive motor 140 is parallel to the output shaft of the first drive motor 22. The converter 150 has a first connecting part 1501 and a second connecting part 1502 with an axial structure. The first connecting part 1501 and the second connecting part 1502 are parallel, and the first connecting part 1501 is coaxially fixedly connected to the output shaft of the second drive motor 140. One end of the crank 160 is rotatably sleeved on the second connecting part 1502, and the other end of the crank 160 is rotatably connected to the docking part 130 with the axis of rotation parallel to the second connecting part 1502. Thus, a linkage transmission structure as in the prior art can be formed. The rotation of the output shaft of the second drive motor 140 can be converted into the swinging of the docking member 130 within a certain angle range through the conversion member 150 and the crank 160. When the needle 94 is aligned with the bottle mouth of the PP bottle 120 by the rotation of the connecting member 21, the output shaft of the second drive motor 140 drives the docking member 130 to swing, thereby causing the bottle mouth of the PP bottle 120 to move in the direction of alignment with the needle 94, thus enabling the needle 94 and the bottle mouth of the PP bottle 120 to be aligned as quickly as possible, improving efficiency. In this embodiment, in order to reduce friction, a bearing 170 can be provided between the circular surface 211 and the docking member 130. The outer ring of the bearing 170 is locked inside the docking member 130, and the docking member 130 is sleeved on the outside of the circular surface 211 through the bearing 170. The support member 8 indirectly realizes the connection with the mounting base 1.
[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
