[0023] For an example, please refer to... Figure 1-4 This utility model provides a technical solution:

[0024] An ultra-high pressure split hydraulic jack includes a jack body 1, a top support rod 2 connected to the jack body 1, and a quick-fixing structure 3 connected to the inner cavity of the top support rod 2;

[0025] In this embodiment, reference Figure 1 , Figure 2 , Figure 3 and Figure 4The quick-fixing structure 3 includes a movable push rod 301 connected to the inner cavity of the top support rod 2. A movable connecting plate 302 is connected to the bottom of the movable push rod 301 within the inner cavity of the top support rod 2. Multiple sets of connecting rods 303 are connected to the movable connecting plate 302. A rotating connecting rod 304 is connected to the side wall of the connecting rod 303. A fixed connecting plate 305 is connected to the bottom of the rotating connecting rod 304 and is located at the bottom of the inner cavity of the top support rod 2. A return spring 306 is connected between the movable connecting plate 302 and the fixed connecting plate 305. A connecting block 307 is connected to the end face of the rotating connecting rod 304. A connecting hole is provided at the center of the top support rod 2, corresponding to the movable push rod 301. The movable push rod 301 is slidably connected to the connecting hole using a tool. Press down on the moving push rod 301, causing it to move downwards, which in turn moves the moving connecting plate 302 downwards. A sliding groove is provided on the moving connecting plate 302, corresponding to the connecting rod 303. The connecting rod 303 is slidably connected to the sliding groove. The connecting rod 303 is fixedly connected to the rotating connecting rod 304, with an included angle of 45 degrees between them. The rotating connecting rod 304 is connected to the fixed connecting plate 305 via a rotating shaft. Under the condition that the rotating connecting rod 304 is rotatably connected to the rotating shaft, multiple sets of rotating connecting rods 304 are rotated inwards, which in turn rotates the connecting block 307, causing the connecting block 307 to separate from the connecting groove. At this point, the top support rod 2 can be removed to complete the disassembly of the hydraulic jack.

[0026] Furthermore, a connecting hole is provided at the center of the top support rod 2, corresponding to the movable push rod 301. The movable push rod 301 is slidably connected to the connecting hole. A sliding groove is provided on the movable connecting plate 302, corresponding to the connecting rod 303. The connecting rod 303 is slidably connected to the sliding groove. The connecting rod 303 is fixedly connected to the rotating connecting rod 304, with an included angle of 45 degrees between them. The rotating connecting rod 304 is connected to the fixed connecting plate 305 via a rotating shaft, with the rotating connecting rod 304 being rotatably connected to the rotating shaft. A connecting slot is provided on the jack body 1, corresponding to the connecting block 307. The connecting block 307 and the connecting slot are clearance-fitted. A guide surface is provided on the side wall of the connecting block 307. Through the interaction between the various components in the quick-fixing structure 3, the quick-fixing structure 3 can operate smoothly during use.

[0027] The working process of this utility model is as follows: When using the ultra-high pressure split hydraulic jack, a connecting slot is first opened on the jack body 1 and corresponding to the connecting slot 307. The connecting slot 307 and the connecting slot are fitted with a clearance fit. With the connecting slot 307 having a guide surface on its side wall, the connecting slot 307 is aligned with the connecting slot and pressed down. Under the action of the return spring 306, the connecting slot 307 and the connecting slot are connected to each other, thereby completing the installation of the hydraulic jack.

[0028] When disassembly is required after use, a connecting hole is provided at the center of the top support rod 2, corresponding to the movable push rod 301. The movable push rod 301 is slidably connected to the connecting hole. Using a tool, the movable push rod 301 is pressed downwards, causing it to move downwards, which in turn moves the movable connecting plate 302 downwards. A sliding groove is provided on the movable connecting plate 302, corresponding to the connecting rod 303. The connecting rod 303 is slidably connected to the sliding groove. The connecting rod 303 is fixedly connected to the rotating connecting rod 304, wherein the included angle between the connecting rod 303 and the rotating connecting rod 304 is 45 degrees. The rotating connecting rod 304 is connected to the fixed connecting plate 305 through a rotating shaft. Under the condition that the rotating connecting rod 304 and the rotating shaft are connected by rotation, multiple sets of rotating connecting rods 304 are driven to rotate inward, which in turn drives the connecting block 307 to rotate, so that the connecting block 307 is separated from the connecting slot. At this time, the top support rod 2 can be removed to complete the disassembly of the hydraulic jack.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
