[0036] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0037] refer to Figures 1-8 , including a main rod 1 and a secondary rod 2, the secondary rod 2 is slidably sleeved above the main rod 1, a pulley base 3 is fixed at the bottom of the main rod 1 for overall movement, and a bottle hanging rack 4 is fixed at the top of the secondary rod 2;

[0038] A sub-control mechanism 5 is arranged between the auxiliary rod 2 and the bottle hanging rack 4, and an extension mechanism 6 is swung on both sides of the auxiliary rod 2 through the sub-control mechanism 5. The extension mechanism 6 includes a first clamping rod 61 and a second clamping rod 62. The second clamping rod 62 is movably arranged on the surface of the first clamping rod 61 through an L-shaped rod 64 on one side of the first clamping rod 61. Four groups of L-shaped rods 64 are fixed on the surface of the second clamping rod 62. A wire clamping groove 65 is arranged on the surface of the L-shaped rod 64. A wire setting groove 63 is arranged on the surface of the first clamping rod 61. The wire clamping groove 65 and the wire setting groove 63 are aligned with each other through an adjusting bolt 66 to firmly clamp the catheter of the hanging liquid bottle at the bottom of the bottle hanging rack 4.

[0039] The sub-control mechanism 5 includes an inner frame 51 and a handle 52. A meshing tooth 53 is fixed on one side of the handle 52. A first mating tooth 57 and a second mating tooth 58 are provided on the side of the inner frame 51. The meshing tooth 53 can be meshed with the first mating tooth 57 and the second mating tooth 58 respectively. The first mating tooth 57 is connected to the extension mechanism 6 by transmission, and the second mating tooth 58 is connected to the side extension mechanism 7 by transmission.

[0040] The side expansion mechanism 7 is arranged at the bottom of the auxiliary rod 2. The side expansion mechanism 7 includes two groups of wire rods 71 ​​and a transmission assembly 76. The two groups of wire rods 71 ​​can be horizontally rotated in the slides 74 on both sides of the auxiliary rod 2 through the sliding rods 73 fixed at the bottom of the rotating seat 72, and the wire rods 71 ​​and the rotating seat 72 can be longitudinally rotated.

[0041] In this embodiment, the liquid medicine bottle is hung on the bottle hanging rack 4, which is supported by the auxiliary rod 2 and the main rod 1, and the pulley base 3 provides the ability of portable movement. The main rod 1, the auxiliary rod 2, the pulley base 3 and the bottle hanging rack 4 constitute a traditional liquid hanging rack;

[0042] The extension mechanism 6 arranged on both sides of the auxiliary rod 2 includes a first clamping rod 61 and a second clamping rod 62. The first clamping rod 61 and the second clamping rod 62 can be adjusted in position by adjusting the bolt 66, so that the clamping groove 65 and the wire placement groove 63 can position the infusion line at the bottom of the medicine bottle to prevent the infusion tubes from being entangled due to being too close to each other. The extension mechanism 6 can be controlled by the sub-control mechanism 5 to swing longitudinally. When not in use, the sub-control mechanism 5 can be used to control the two sets of the first clamping rod 61 and the second clamping rod 62 to swing relative to each other, so as to achieve storage.

[0043] The sub-control mechanism 5 includes an inner frame 51 and a handle 52. After rotating the handle 52, it can directly drive the meshing teeth 53 to rotate. The meshing teeth 53 can mesh with the first docking teeth 57 and the second docking teeth 58 respectively. When the first docking teeth 57 rotate, the two sets of abduction mechanisms 6 swing. After the second docking teeth 58 rotate, they can control the operation of the side expansion mechanism 7. When the side expansion mechanism 7 operates, it can drive the two sets of wire rods 71 to swing, so that they rotate to different vector directions from the first clamping rod 61 and the second clamping rod 62 and comb the electric wires, thus achieving the classification effect and preventing the problem of mutual entanglement and knotting caused by the same direction of the two lines.

[0044] Reference Figures 1-7 , a number of groups of wire wheels 78 are fixed on the surface of the wire rod 71. The wire wheels 78 are used to comb the electric wires. One side of the rotating seat 72 is longitudinally rotatably connected to the wire rod 71 through a fixed hinge shaft. A contact pin 79 is also fixed at the position of the wire rod 71 close to the rotating seat 72. The wire rod 71 is in contact support with the rotating seat 72 through the contact pin 79. A frame-shaped pull rod 75 is slidably arranged below the sliding rod 73. Two sets of contact springs 77 are fixed on the surface of the frame-shaped pull rod 75. The sliding rod 73 penetrates through the sliding table 74 on the side of the auxiliary rod 2. One end of the contact spring 77 at the top of the frame-shaped pull rod 75 is elastically in contact with the bottom of the sliding table 74, and one end of the contact spring 77 at the bottom of the frame-shaped pull rod 75 is in contact with the convex ring at the bottom of the sliding rod 73. The transmission component 76 includes a rib plate 761 and two sets of arc-shaped meshing teeth 762. The two sets of arc-shaped meshing teeth 762 are respectively fixed at one end of the hinge shaft at the connection of the two sets of wire rods 71 and the rotating seat 72. The arc-shaped meshing teeth 762 are meshed and connected with the side surface of the rib plate 761. A meshing rod 763 is fixedly connected to the top of the rib plate 761. One side of the meshing rod 763 meshes with a transmission gear 764. The transmission gear 764 is movably arranged on the surface of the auxiliary rod 2 through a limiting shaft. A pulley assembly 765 is fixed on one side of the transmission gear 764. A driven gear 766 is fixed at the top of the pulley assembly 765 through a pulley. The driven gear 766 is movably connected to the limiting shaft at the bottom of the inner frame 51. The driven gear 766 meshes with the bottom of the second docking teeth 58. The handle 52 is movably arranged on one side of the side plate 54 through a bearing. The other side of the side plate 54 away from the handle 52 is rotatably arranged on the convex shaft on the surface of the inner frame 51. A positioning hole 55 is opened on the surface of the side plate 54. A positioning pin 56 is inserted into the positioning hole 55. The positioning pin 56 is inserted into the hole groove opened on the surface of the inner frame 51. The axial center positions of the first docking teeth 57 and the second docking teeth 58 are at the same distance from the rotation center position between the side plate 54 and the inner frame 51.

[0045] In this embodiment, an electric wire is passed through a wire wheel 78 on the surface of a wire rod 71. The wire wheel 78 provides a separating and combing effect. The connection position between the wire rod 71 and the rotating seat 72 is rotationally connected through a hinge shaft. This rotation direction is the same as the rotation direction of the abduction mechanism 6, both being longitudinal rotations. A slide rod 73 is fixed to the bottom of the rotating seat 72. The slide rod 73 passes through a slide table 74 and is movable within the slide table 74. In this way, the rotating seat 72 can also rotate within the slide table 74 through the slide rod 73, driving the wire rod 71 and the wire wheel 78 to rotate in another direction. At this time, the orientation of the wire rod 71 and the orientation of the abduction mechanism 6 form a 90-degree angle in the plane. In this way, the two wires will be separated from each other, and even if the wires come into contact with each other, they will not get entangled and knotted;

[0046] A frame-shaped pull rod 75 slidably arranged at the bottom of the slide rod 73 contacts the convex ring at the bottom of the slide rod 73 and the bottom surface of the slide table 74 through two sets of abutting springs 77 respectively. Under normal circumstances, the elastic abutting effect of the two sets of abutting springs 77 will keep the slide rod 73 stable within the slide table 74. When the frame-shaped pull rod 75 is pulled downward, at this time, the abutting spring 77 between the lower part of the frame-shaped pull rod 75 and the slide rod 73 is compressed and deformed, and the abutting spring 77 between the top of the frame-shaped pull rod 75 and the slide table 74 will be separated from the slide table 74. At this time, if the frame-shaped pull rod 75 is rotated, it will drive the slide rod 73, the rotating seat 72, and the wire rod 71 as a whole to rotate within the slide table 74 under the action of elastic torsional force, so as to achieve the movement effect. On the contrary, after the frame-shaped pull rod 75 is released, under the elastic abutting force of the abutting spring 77, the slide rod 73 is positioned with the slide table 74 again, thus realizing the positioning of the wire rod 71;

[0047] The hinge shaft connecting the rotating seat 72 and the wire rod 71 is fixed to the wire rod 71. At the same time, an arc-shaped tooth 762 is fixed to one side of the hinge shaft. Two wire rods 71 correspond to two arc-shaped teeth 762. The rib plate 761 between the two arc-shaped teeth 762 is slidably arranged on the side of the auxiliary rod 2. When the rotating seat 72 rotates a certain angle within the slide table 74 through the slide rod 73, the arc-shaped tooth 762 can be arc-shapedly engaged with the side surface of the rib plate 761. This engagement effect will enable the arc-shaped tooth 762 to drive the wire rod 71 to swing longitudinally within the rotating seat 72 when the rib plate 761 descends or ascends, so as to cooperate with the abduction mechanism 6 to achieve storage;

[0048] The ratchet rod 763 fixed to the top of the rib plate 761 directly meshes with the transmission gear 764. One side of the transmission gear 764 is fixed to the pulley at the bottom of the pulley assembly 765. The pulley at the top of the pulley assembly 765 is fixed with the driven gear 766. The driven gear 766 directly meshes with the second docking tooth 58. And the second docking tooth 58 and the meshing tooth 53 can achieve docking and meshing. In this case, only by turning the handle 52, the side plate 54 will swing. The distance from the swing center to the first docking tooth 57 and the second docking tooth 58 is the same, so that the meshing tooth 53 can be driven to mesh with the first docking tooth 57 and the second docking tooth 58 respectively. When the meshing tooth 53 meshes with the second docking tooth 58, by pushing the positioning pin 56 inside the positioning hole 55, it is inserted and positioned with the hole groove on the surface of the auxiliary rod 2. At this time, turning the handle 52 again drives the meshing tooth 53 to rotate. The meshing effect between the meshing tooth 53 and the second docking tooth 58 will drive the driven gear 766 to rotate, thereby realizing the up and down movement of the rib plate 761.

[0049] Reference Figure 6 and Figure 7 On one side of the first clamping rod 61, the auxiliary turbine 67 is fixed through a coupling shaft. The coupling shaft is movably arranged at the bottom of the inner frame 51 through a support seat. The auxiliary turbine 67 meshes with one side of the triple worm rod 68. The triple worm rod 68 is rotatably arranged inside the inner frame 51 through a limit seat. The middle position of the triple worm rod 68 meshes with the main turbine 69. The main turbine 69 is fixed with a bevel gear set 610 at the top. The bevel gear set 610 is composed of two bevel gears that mesh at a right angle with each other. One side of the bevel gear set 610 is fixedly connected to the first docking tooth 57.

[0050] In this implementation scheme, when the first docking tooth 57 is driven to rotate by the meshing tooth 53, at this time, the first docking tooth 57 will directly drive the main turbine 69 to rotate inside the inner frame 51 through the bevel gear set 610. The triple worm rod 68 meshing with one side of the main turbine 69 is forced to rotate. The two ends of the triple worm rod 68 mesh with the auxiliary turbine 67, so that the auxiliary turbine 67 is forced to rotate. And the auxiliary turbine 67 is fixed to the first clamping rod 61. The first clamping rod 61 is forced to rotate, and thus the flipping and storage of the first clamping rod 61 and the second clamping rod 62 can be realized.

[0051] Reference Figure 3 and Figure 8 Between the bottom of the auxiliary rod 2 and the main rod 1, an adjusting mechanism 8 is further provided. The adjusting mechanism 8 includes a pressure rod 81 and a plurality of groups of jacks 84. The pressure rod 81 is angled. And both sides of the pressure rod 81 are rotatably connected to the side surface of the auxiliary rod 2 through convex shafts. One end of the pressure rod 81 is elastically connected to the auxiliary rod 2 through a pressure spring 83. A plug protrusion 82 is fixed at the end of the pressure rod 81 far from the pressure spring 83. The jacks 84 are arranged in an equidistant straight line on the surface of the main rod 1. A through groove is opened at the position of the auxiliary rod 2 close to the plug protrusion 82. The plug protrusion 82 is clamped with the jacks 84.

[0052] In this embodiment, the telescopic effect between the secondary rod 2 and the main rod 1 can achieve height adjustment. Specifically, by pressing the pressure rod 81 on the side of the secondary rod 2, one end of it squeezes the pressure spring 83, and the other end drives the insertion protrusion 82 to withdraw from the insertion hole 84 on the surface of the main rod 1. At this time, the telescopic secondary rod 2 and the main rod 1 are extended or retracted, and then the pressure rod 81 is released. Under the elastic force of the pressure spring 83, the insertion protrusion 82 is inserted and fixed with the new insertion hole 84, so as to realize the height positioning of the secondary rod 2 and the main rod 1.

[0053] Working principle: First, pull the positioning pin 56 on the surface of the side plate 54, so that it slides in the positioning hole 55 and separates from the hole groove on the surface of the secondary rod 2. Then grab the handle 52 and lift the side plate 54 and the meshing teeth 53 upward, so that the meshing teeth 53 mesh with the bottom of the first docking tooth 57. Then insert the positioning pin 56 for position fixing. At this time, rotate the handle 52, and the meshing teeth 53 rotate to drive the first docking tooth 57 to rotate. One side of the first docking tooth 57 directly drives the main turbine 69 to rotate under the transmission effect of the bevel gear group 610 inside the inner frame 51. One side of the main turbine 69 engages with the triple worm 68, and both sides of the triple worm 68 engage with the secondary turbines 67 respectively. After the secondary turbines 67 rotate, they drive the first clamping rod 61 and the second clamping rod 62 to rotate, so that the first clamping rod 61 and the second clamping rod 62 are flush with the bottom of the hanging bottle rack 4. Then, by rotating the adjusting bolt 66 at one end of the first clamping rod 61, the second clamping rod 62 is forced to move. Here, the movement refers to the movement of threaded connection. Then, the L-shaped rod 64 on the surface of the second clamping rod 62 drives the wire clamping groove 65 to approach the wire placement groove 63 on the surface of the first clamping rod 61. Under the mutual approach of the wire clamping groove 65 and the wire placement groove 63, the infusion tube is positioned and separated;

[0054] Subsequently, drive the meshing teeth 53 to engage with the second docking tooth 58 again. At this time, after rotating the meshing teeth 53, the second docking tooth 58 drives the driven tooth 766 to rotate. The driven tooth 766 directly drives the transmission tooth 764 to rotate through the pulley assembly 765. One side of the transmission tooth 764 engages with the rod 763. The rod 763 is forced to drive the rib plate 761 to move downward. The arc-shaped meshing teeth 762 on both sides of the rib plate 761 are forced to rotate, and the arc-shaped meshing teeth 762 drive the wire rod 71 to swing through the hinge shaft until the contact pin 79 on the surface of the wire rod 71 contacts the rotating seat 72. At this time, the basic unfolding effect is completed. On the contrary, the storage is realized. Then, pull the frame-shaped pull rod 75 on the surface of the sliding rod 73 at the bottom of the rotating seat 72, so that the top of the frame-shaped pull rod 75 contacts the spring 77 and separates from the bottom of the sliding table 74, and rotate the frame-shaped pull rod 75. Under the contact force between the bottom of the frame-shaped pull rod 75 contacting the spring 77 and the sliding rod 73, the sliding rod 73 is driven to rotate inside the sliding table 74, so that the whole rotating seat 72 is forced to drive the wire rod 71 to rotate horizontally. In this way, the direction of the wire rod 71 is staggered from the direction of the first clamping rod 61. Then, insert the electric wire through the wire wheel 78 on the surface of the wire rod 71 to realize the combing of the electric wire;

[0055] Finally, press the pressure lever 81 on the surface of the secondary rod 2, squeezing the pressure spring 83 to deform. At the same time, the insertion protrusion 82 is withdrawn from the insertion hole 84 on the surface of the main rod 1, extending the main rod 1 and the secondary rod 2.
