Compared with the method in the prior art that the fixing device needs to be replaced after the size of the simulated heart 800 changes, when the size of the simulated heart 800 changes, the position of the first adjustment part on the first adjustment component 500 is adjusted, and the position of the second adjustment part is correspondingly adjusted by the second adjustment component 600, so as to match the size of the simulated heart 800. Simulated hearts 800 of various sizes can be fixed, avoiding the trouble of replacing equipment.

[0036] In one embodiment, Figure 3 and Figure 4 As shown, the clamping mechanism 200 includes a mounting member 210 disposed on the support platform 100, a receiving groove 220 disposed on the mounting member 210 for receiving the first connecting tube 300, and a stopper 230 covering the mouth of the receiving groove 220 to limit the first connecting tube 300 in the receiving groove 220. Specifically, the mounting member 210 refers to a member with a certain volume, and the mounting member 210 can be a plate-shaped member with a relatively thin thickness, and the mounting member 210 is protruding from the surface of the support platform 100. The receiving groove 220 refers to a groove disposed on the mounting member 210, and the length direction of the receiving groove 220 runs through the thickness dimension of the entire mounting member 210, so that both ends of the receiving groove 220 are open structures, and the function of the receiving groove 220 is to receive the first connecting tube 300, and the depth of the receiving groove 220 matches the diameter of the first connecting tube 300. In order to ensure that the first connecting tube 300 is firmly fixed, the depth of the receiving groove 220 can be slightly smaller than the diameter of the first connecting tube 300. The stopper 230 refers to a block member, and the stopper 230 can be in any of the shapes of a block, a plate or a strip. When the first connecting tube 300 is fixed, the first connecting tube 300 is placed in the receiving groove 220, and the length direction of the first connecting tube 300 is parallel to the length direction of the receiving groove 220, and the first connecting tube 300 extends from the open structures at both ends of the receiving groove 220. Then, the stopper 230 is covered at the mouth of the receiving groove 220, and the first connecting tube 300 is surrounded in the middle by the bottom surface of the stopper 230 and the side wall of the receiving groove 220, so as to realize the compression and fixation of the first connecting tube 300.

[0037] In one embodiment, Figure 4 As shown, a disassembly structure is further provided between the stopper 230 and the mounting member 210, and the stopper 230 is detachably connected to the mounting member 210 through the disassembly structure. Specifically, the disassembly structure can facilitate the disassembly and installation of the stopper 230, and the first connecting tube 300 can be quickly fixed and removed during the experiment, which can make the fixing and removal of the simulated heart 800 faster and more convenient, thereby improving the efficiency of the experiment.

[0039] In one embodiment, Figure 4 As shown, the limiting member 230 is provided with a first plug-in portion 240, and the mounting member 210 is provided with a second plug-in portion 250 that plugs and cooperates with the first plug-in portion 240. The limiting member 230 is detachably connected to the mounting member 210 through the first plug-in portion 240 and the second plug-in portion 250. Specifically, the first plug-in portion 240 and the second plug-in portion 250 refer to components that can realize the mutual plug-in cooperation between the limiting member 230 and the mounting member 210, wherein the first plug-in portion 240 can be any one of a columnar member, a plate-shaped member or a block-shaped member, and the second plug-in portion 250 is a plug-in hole that matches the shape of the first plug-in portion 240, and the surface of the first plug-in portion 240 is connected to the plug-in hole; the second plug-in portion 250 can be any one of a columnar member, a plate-shaped member or a block-shaped member, and in this case, the first plug-in portion 240 is a plug-in hole that matches the shape of the second plug-in portion 250.

When the external force applied to the stopper 230 is greater than the friction force at the contact surface of the first plug-in part 240 and the second plug-in part 250, the first plug-in part 240 and the second plug-in part 250 will be disengaged. When the external force applied to the stopper 230 is greater than the friction force at the contact surface of the first plug-in part 240 and the second plug-in part 250 or when no force is applied to the stopper 230, the first plug-in part 240 and the second plug-in part 250 remain connected under the action of friction, making the installation and removal of the stopper 230 more convenient and also making the fixation of the first connecting pipe 300 more convenient.

[0041] In an optional embodiment, if Figure 4 As shown, there are two first plug-in parts 240 and two second plug-in parts 250. The two second plug-in parts 250 are located on both sides of the accommodating groove 220.

Specifically, the limiting portion 260 refers to a component with a certain volume, and the limiting portion 260 can be any one of a block component, a plate component, etc. The limiting groove on the first connecting pipe 300 refers to a groove arranged on the outer wall of the first connecting pipe 300 and arranged along the circumference of the first connecting pipe 300. The limiting groove can be directly recessed on the outer wall of the first connecting pipe 300, or two annular components can be arranged on the outer wall of the first connecting pipe 300 at intervals, and the limiting groove is formed between the two annular components. When the limiting member 230 is installed on the mounting member 210, at least a portion of the limiting portion 260 extends from the mouth of the receiving groove 220 into the receiving groove 220. When the first connecting tube 300 is located in the receiving groove 220 , the limiting portion 260 will be snapped into the limiting groove, which can prevent the first connecting tube 300 from sliding along its own axis to a certain extent, making the installation of the first connecting tube 300 in the receiving groove 220 more firmly and stably.

Specifically, the first adjustment frame 510 can be a single component or a complex shape composed of multiple components. The first connecting member 560 refers to a member that can be connected to the second connecting tube 400. The first connecting member 560 may be provided with a clamping structure for accommodating the second connecting tube 400, or the first connecting member 560 may be connected to the second connecting tube 400 by clamping, threading, or gluing. By sliding the first adjustment frame 510 along the first direction X and the first connecting member 560 along the second direction Y, the second connecting tube 400 can be adjusted in multiple dimensions, so that the adjustment range of the second connecting tube 400 is larger.
