Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-4 The present invention provides a technical solution: an intervention trolley cantilever fixing structure, characterized in that it includes: a cantilever 1, a clamping rail 2, which is fixedly connected to the bottom of the cantilever 1, a trolley slide groove 3 is slidably connected inside the clamping rail 2, a slide groove connecting block 4 is fixedly connected to the right side of the trolley slide groove 3, and a longitudinal pressing structure for fixing the trolley slide groove 3 is provided on the left side of the clamping rail 2.

[0029] Please see Figure 3 The intervention trolley cantilever fixing structure and longitudinal clamping structure also include:

[0030] A Torx screw fixing block 5 is fixedly connected to the left side of the clamping rail 2. A Torx handle screw 6 is provided on the left side of the Torx screw fixing block 5. A acetal block 7 located on the left side of the trolley slide 3 is provided inside the clamping rail 2. The right end of the Torx handle screw 6 passes through the Torx screw fixing block 5 and extends into the interior of the acetal block 7. A hexagonal nut 8 located on the left side of the Torx screw fixing block 5 is threadedly connected to the surface of the Torx handle screw 6. The hexagonal nut 8 is fixedly connected to the Torx screw fixing block 5. A tensioning block 9 sleeved on the surface of the Torx handle screw 6 is fixedly connected to the surface of the Torx handle screw 6. A thin nut 10 located inside the acetal block 7 is fixedly connected to the surface of the Torx handle screw 6. By setting the Torx screw fixing block 5, Torx handle screw 6, and acetal block 7, pressure can be used to squeeze and fix the trolley slide 3 to prevent it from sliding. The clamping rail 2 also includes: a connecting sheet metal 11, which is fixedly connected to the left side of the clamping rail 2. The top of the connecting sheet metal 11 is connected to the suspension. The bottom of arm 1 is fixedly connected. By setting the connecting sheet metal 11, the contact area between the clamping rail 2 and the cantilever 1 can be increased, further improving the installation stability of the clamping rail 2. The clamping rail 2 also includes: a acetal gasket 12, which is installed inside the clamping rail 2. The acetal gasket 12 is located at the top of the trolley slide 3. By setting the acetal gasket 12, the trolley slide 3 can be limited to prevent the trolley slide 3 from shaking up and down. The clamping rail 2 also includes: a guide block 13, which is fixedly connected to the front and back of the clamping rail 2. The inner surface of the guide block 13 is set to be inclined inward.

Both ends of the acetal gasket 12 extend to the outside of the trolley slide 3 and are detachably connected to the trolley slide 3 by bolts.

[0031] Working principle: For this type of interventional trolley cantilever fixing structure, firstly, the slide rail connecting block 4 is fixed to the external trolley, and the trolley slide rail 3 is fixed to the slide rail connecting block 4 with screws. After passing through the guide block 13, it slides into the clamping rail 2. Inside the clamping rail 2, a acetal washer 12 is installed to limit the vertical position. When the trolley slide rail 3 is connected, firstly, a hexagonal nut 8 and a acetal screw fixing block 5 are installed on the surface of the acetal screw 6. The thin nut 10 is glued to the acetal screw 6 with thread adhesive. Then, the tensioning block 9 and the acetal block 7 with internal space are connected with screws. Finally, the entire assembly is connected to the clamping rail 2. When the trolley slide rail 3 slides into the clamping rail 2, the acetal screw 6 is rotated, causing the thin nut 10 at the top of the acetal screw 6 to move to the right, thereby driving the acetal block 7 to press the trolley slide rail 3 to the right to achieve a stable effect.
