[0030] Further, the first fastening component includes a first thread groove 9 and a first threaded post 10, the first thread groove 9 is opened on the first mounting plate 5 and the second mounting plate 8, and the first threaded post 10 is screwed through the first thread groove 9.
[0031] Further, the second fastening component includes a second threaded post 12 and a second thread groove 13, the second threaded post 12 is installed at one end of the push rod 11, the second thread groove 13 is opened on the main shaft body 7, and the second threaded post 12 and the second thread groove 13 are adapted to each other.
[0032] Further, one end of the push rod 11 away from the second threaded post 12 is connected with a mounting block 14, and an anti-slip groove 15 is opened on the outer wall of the mounting block 14.
[0033] Through the above technical solution:
[0034] During use, lay the equipment horizontally, align the first thread grooves 9 on the first mounting plate 5 and the second mounting plate 8, and screw the first threaded post 10. Through the interaction between the first thread groove 9 and the first threaded post 10, the first mounting plate 5 and the second mounting plate 8 are fastened, and then the hydraulic motor body 6 is installed. Then align the second threaded post 12 and the second thread groove 13, and drive the second threaded post 12 on the push rod 11 to be screwed into the second thread groove 13 by rotating the mounting block 14. The anti-slip groove 15 can increase the friction between the hand and the mounting block 14, facilitating the screwing operation.

After the installation is completed, start the hollow jack 1, the hollow jack 1 drives the push rod 11 to move, and the moving push rod 11 pulls out and disassembles the main shaft body 7 from the hydraulic motor body 6. The device that can easily disassemble the main shaft body 7 can improve the work efficiency and make the main shaft body 7 not easily damaged.
[0035] Please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 7As shown in the figure, a connecting column 16 is installed on the outer wall of the fixing plate 2. A hollow column 17 is provided below the connecting column 16, and a part of the connecting column 16 is located inside the hollow column 17. A support plate 18 is installed at the bottom end of the hollow column 17, and a limiting component is provided between the connecting column 16 and the hollow column 17.
[0036] Furthermore, a vertical spring 19 is installed between the connecting column 16 and the hollow column 17, and a soft pad 20 is installed at the bottom end of the support plate 18.
[0037] Furthermore, the limiting component includes a limiting groove 21 and a limiting block 22. The limiting groove 21 is opened on the inner wall of the hollow column 17, the limiting block 22 is installed on the outer wall of the connecting column 16, and the limiting groove 21 and the limiting block 22 are adapted to each other.
[0038] Through the above technical solutions:
[0039] When the device is laid horizontally, the side where the support plate 18 is installed contacts the ground, thus pressing the soft pad 20 to deform. The molecular structure inside the soft pad 20 is rearranged, converting the impact energy into heat energy or other forms of energy, thereby reducing the energy transmitted to the device. The connecting column 16 moves inside the hollow column 17, and the spring 19 expands and contracts. This telescopic action prolongs the action time of the impact force. A buffer system is provided through the combination of the soft pad 20 and the spring 19, and their combined action can effectively absorb and disperse the impact energy, thereby reducing the impact force when the device contacts the ground, protecting the device, and increasing the service life of the device. When the connecting column 16 moves, it drives the limiting block 22 to move inside the limiting groove 21, so that the connecting column 16 only moves up and down inside the hollow column 17, is not easy to sway left and right, and improves the stability of the device.
[0040] Furthermore, please refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown in the figure, a connecting block 23 is installed on the outer wall of the hollow plate 3. A third thread groove 24 is opened on the connecting block 23, and a roller assembly is connected to the connecting block 23.
[0041] Furthermore, the roller assembly includes a third threaded column 25 and a rolling wheel 26. The third threaded column 25 is screwed and installed in the third thread groove 24, and the rolling wheel 26 is installed at the bottom end of the third threaded column 25.
[0042] Specifically, when the device needs to be moved, the third threaded post 25 is screwed. Through the interaction between the third threaded post 25 and the third threaded groove 24, the rolling wheel 26 is installed. The detachable rolling wheel 26 enables the device to easily change from a stationary state to a movable state when it needs to be moved, which is especially convenient when moving large or heavy equipment. The detachable rolling wheel 26 can be installed or removed as needed, making the device more flexible to adapt to various ground conditions.
[0043] Further, please refer to Figure 1 、 Figure 2 and Figure 7 As shown, a handle 27 is installed on the outer wall of the hollow jack 1, and an anti-slip pad 28 is installed on the handle 27.
[0044] Specifically, the outer wall of the hollow jack 1 is smooth, making it inconvenient to carry the whole device. By installing the handle 27, a more stable grip can be provided. The anti-slip pad 28 increases the friction between the hand and the handle 27, reducing the risk of the device falling or sliding.
