[0047] Further, the fixing member 202 comprises a positioning column 202a, and a limiting groove 202b arranged in the outer wall of the positioning column 202a.

[0048] The positioning column 202a penetrates through the mounting frame 201 and is threadedly connected with the top of the mounting shell 101.

[0049] Further, the limiting frame 203 comprises a connecting plate 203a, and a limiting rod 203b and a stand column 203c arranged at the lower surface of the connecting plate 203a.

[0050] Further, the rotating block 301 comprises a fixed block 301a, and snap rings 301b arranged at the top and bottom of the fixed block 301a.

[0051] It should be noted that the mounting frame 201 comprises the mounting plates 201a, and the number of the mounting plates 201a is two, the two mounting plates 201a are “A type plates without horizontal bars”, and the two mounting plates 201a are fixed by the connecting columns 201b after being aligned, thereby constituting the mounting frame 201, and the inner side surface of each of the two mounting plates 201a is provided with the fixing groove 201c, the rotating block 301a is rotatably connected in the fixing groove 201c by embedding the snap rings 301b at both ends of the rotating block 301a into the fixing groove 201c, the fixing member 202 is mainly composed of the positioning column 202a, the bottom end of the positioning column 202a is provided with a threaded groove, the positioning column 202a is threadedly connected with the top of the mounting shell 101 through the threaded groove, the limiting groove 202b is arranged outside the main body of the positioning column 202a, the limiting frame 203 comprises the connecting plate 203a, the limiting rod 203b and the stand column 203c are fixedly connected at the lower surface of the connecting plate 203a, the limiting cap 303 slides on the outer wall of the limiting rod 203b, and the limiting rod 203b can prevent the threaded rod 302 from rotating.

The transmission belt 403 is sleeved on both the drive wheel 401 and the driven wheel 402.

[0054] In use, the mounting housing 101 is first securely installed in the working area using the connecting assembly 103. Next, the component to be pushed is connected to the threaded rod 302 using the connecting cap 304. Then, the reciprocating motor 104 is started, and its output end begins to rotate. This rotation is transmitted to the rotating block 301 through the transmission assembly 400, causing it to rotate synchronously.

[0055] It is worth noting that the rotating block 301 and the threaded rod 302 are connected by a thread, while the threaded rod 302 is fixed by the limiting bracket 203 and cannot rotate on its own.

[0057] Example 2

[0058] Reference Figures 1-5 In the second embodiment of the present invention, based on the first embodiment, a connecting component 103 is further provided. The connecting component 103 includes a second connecting plate, a horizontal plate disposed on the outer wall of one side of the second connecting plate, and a third connecting plate disposed at one end of the horizontal plate. Each inflection point of the third connecting plate is provided with a through hole.

[0059] It should be noted that the connecting assembly 103 consists of a second connecting plate, a horizontal plate, and a third connecting plate, and the three together form an "I-shaped part". The connection is achieved by bolts passing through the third connecting plate and tightening them in the installation area.

[0060] In use, the mounting shell 101 is fixed by passing the bottom end of the bolt through the through hole and tightening it in the mounting area, and the recessed area of ​​the "I-shaped part" allows the bolt to pass through the through hole easily.

[0061] It should be noted that the connecting component 103 is a structure composed of a second connecting plate, a cross plate, and a third connecting plate. These three are connected to each other and jointly form a component shaped like the Chinese character "工". During the actual installation process, we use bolts to pass through the through holes on the third connecting plate and firmly tighten them at the corresponding positions in the installation area, thus achieving the stable connection of the entire connecting component 103.

[0062] During use, simply pass the bottom end of the bolt through the through hole on the installation shell 101, and once again use the bolt to tightly connect it to the corresponding position in the installation area. In this process, the unique design of the "工-shaped part" plays a key role. Its recessed area provides sufficient space for the bolt, enabling the bolt to easily pass through the through hole, and thus achieving the quick and stable fixation of the installation shell 101.

[0063] In summary, through the combined use of the "工-shaped part" and the bolt, the installation shell 101 can achieve both quick and stable fixation effects, significantly improving the installation and disassembly efficiency of the equipment, making the entire process smoother and more efficient. The side of the "工-shaped part" is designed as a flat planar structure. This feature enables the propulsion mechanism to be easily and stably installed on any working area with a planar installation surface. Regardless of the specific shape and size of the working area, as long as its surface is flat, the "工-shaped part" can ensure that the propulsion mechanism fits tightly with it, achieving stable and reliable installation.

[0064] Embodiment 3[[ID=IO]]

[0065] Refer to Figures 1-5 , in the third embodiment of the present invention, based on Embodiment 1, this embodiment further provides a connecting component 103. The connecting component 103 includes a second vertical plate, an arc-shaped plate disposed on one side of the second vertical plate, connecting ears disposed at one ends of two adjacent arc-shaped plates, a connecting bolt passing through the connecting ears, and a nut disposed on the connecting bolt.

[0066] It should be particularly noted that two rotatable arc-shaped plates are disposed on one side of the second vertical plate. These two arc-shaped plates can be tightly closed after rotation and jointly form a complete circular collar. A connecting ear is firmly connected to the closed end of each arc-shaped plate, and a connecting bolt passes through these two connecting ears. By screwing a nut tightly on this connecting bolt, we can easily achieve the stable fixation of the installation shell 101 on the circular pipeline.

[0067] During use, we simply wrap the arc-shaped plates around the outer wall of the installation pipeline to ensure they fit tightly. Then, pass the connecting bolt through the two connecting ears and tighten the nut to easily complete the fixed installation of the installation shell 101 on the circular pipeline

[0068] In summary, by skillfully closing and fixing the two arc-shaped plates, the installation shell 101 exhibits both rapid and reliable fixing performance. This design greatly optimizes the installation and disassembly process of the equipment, making the entire process smoother and more efficient. The inner sides of the two arc-shaped plates are designed with curved surfaces, which can perfectly form a circular collar when they are tightly closed, thus easily and stably fixing the installation shell 101 on the circular pipeline. This innovative design not only improves the convenience of installation, but also ensures the stability and durability of the equipment.

[0080] By starting the reciprocating motor 104, the output end starts to rotate, is transmitted to the rotating block 301 through the transmission assembly 400, and is synchronously rotated, the rotating block 301 and the threaded rod 302 are connected in a threaded mode, and the threaded rod 302 is fixed by the limiting frame 203 and cannot rotate, therefore, when the rotating block 301 rotates, it drives the threaded rod 302 to generate linear displacement, the threaded rod 302 drives the piston 502 to slide in the piston barrel 501 through the connecting cap 304, and the reciprocating motor 104 is reversely rotated to realize the extraction and injection effect.

[0081] In summary, by driving the reciprocating motor 104, the precise movement of the threaded rod 302 along the linear track is ingeniously triggered, and the mechanism further drives the syringe to realize the automatic extraction and injection function, in the experimental process, after the experimenter accurately places the injection needle into the mouse, only needs to simply start the reciprocating motor 104, and the injection operation can be smoothly completed, and the cumbersome steps of traditional two-person cooperation are completely abandoned, so that the whole injection process becomes unprecedentedly convenient and efficient.
