[0025] Specifically, a fixing seat 441 is disposed on one side of the sealing cover 44 , a fixing rod 442 is disposed inside the fixing seat 441 , a fixing slider 443 is disposed below the fixing rod 442 , and a fixing spring 444 is disposed on one side of the fixing slider 443 .

[0026] By adopting the above technical solution, when the filter 43 needs to be cleaned or replaced, the fixing rod 442 is pulled, and the fixing rod 442 drives the fixing slider 443 to move and compress the fixing spring 444, so that the fixing rod 442 is disengaged from the fixing hole, and then the sealing cover 44 can be removed, thereby taking out the filter 43 for cleaning or replacement.

[0027] Specifically, one end of the fixed slider 443 is slidably connected to a stabilizing slider rod, and one side of the sealing cover 44 is provided with a fixing hole that matches the fixing rod 442 .

Then the sealing cover 44 can be removed, thereby taking out the filter screen 43 for cleaning or replacement. When the device is in use, it is convenient to filter the oil entering the oil inlet end of the rotating cylinder body 3, thereby improving the practicality of use.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that: specifically, the convenient disassembly and assembly component 6 includes a disassembly and assembly seat 61, a square connecting block 62, a sealing gasket 63, a clamping rod 64, a clamping slider 65 and a clamping spring 66, wherein a disassembly and assembly seat 61 is provided at one end of the oil inlet pipe 5, a square connecting block 62 is inserted into one side of the disassembly and assembly seat 61, a sealing gasket 63 is provided at the connection between the disassembly and assembly seat 61 and the square connecting block 62, a clamping rod 64 is provided above the square connecting block 62, a clamping slider 65 is provided on one side of the clamping rod 64, and a clamping spring 66 is provided above the clamping slider 65.

[0032] By adopting the above technical scheme, the square connecting block 62 is inserted into the disassembly and assembly seat 61. When the square connecting block 62 moves and abuts the clamping rod 64, under the action of the guide slide, the clamping rod 64 is driven to move up, and the clamping rod 64 moves up to drive the clamping slider 65 to move up and compress the clamping spring 66 until the square connecting block 62 moves to coincide with the clamping rod 64 and the clamping hole. The clamping spring 66 is reset, driving the clamping rod 64 to insert the clamping hole to fix the square connecting block 62, thereby completing the installation of the oil pipeline 7. When the oil pipeline 7 needs to be replaced after long-term use, the clamping rod 64 is pulled to disengage from the clamping hole, so that the oil pipeline 7 can be removed and replaced, so that the device can be conveniently used to connect and fix the external oil pipeline 7 with the oil inlet pipe 5 and the oil outlet pipe 8 of the rotating cylinder body 3. At the same time, it is also convenient to quickly replace the oil pipeline 7 when it is damaged after long-term use.

[0033] Specifically, a guide slot is provided at one end of the clamping rod 64 , and a clamping hole matching the clamping rod 64 is provided above the square connecting block 62 .

[0034] By adopting the above technical solution, the guide slide makes it easy for the square connecting block 62 to abut against the clamping rod 64 when it is installed, and can drive the clamping rod 64 to move upward. The clamping hole makes it easy for the clamping rod 64 to be inserted to fix the square connecting block 62.

[0035] When the present embodiment is in use, the square connecting block 62 is inserted into the disassembly and assembly seat 61. When the square connecting block 62 moves and abuts against the clamping rod 64, the clamping rod 64 is driven to move up under the action of the guide slide. The clamping rod 64 moves up and drives the clamping slider 65 to move up and compress the clamping spring 66 until the square connecting block 62 moves to coincide with the clamping rod 64 and the clamping hole. The clamping spring 66 is reset, driving the clamping rod 64 to insert into the clamping hole, fixing the square connecting block 62, thereby completing the installation of the oil pipeline 7. When the oil pipeline 7 needs to be replaced after long-term use, the clamping rod 64 is pulled to disengage from the clamping hole, so that the oil pipeline 7 can be removed and replaced. When the device is in use, it is convenient to connect and fix the external oil pipeline 7 to the oil inlet pipe 5 and the oil outlet pipe 8 of the rotating cylinder body 3. At the same time, it is also convenient to quickly replace the oil pipeline 7 when it is damaged after long-term use.

[0036] Working principle and use process of the utility model: when the utility model is in use, the angle of the center leg body 2 can be rotated and adjusted by rotating the oil cylinder body 3, so that when the center leg is restricted, the angle can be adjusted. When the rotating oil cylinder body 3 is in use, the hydraulic oil that can enter is filtered through the filter component 4 to prevent impurities from entering. The oil delivery pipe 7 can be quickly connected and fixed through the convenient disassembly and assembly component 6. When the filter component 4 is in use, the hydraulic oil enters the filter seat 41, is filtered through the filter screen 43, and then the inside of the rotating oil cylinder body 3 is rotated. When the filter screen 43 needs to be cleaned or replaced, the fixing rod 442 is pulled, and the fixing rod 442 drives the fixing slider 443 to move and compress the fixing spring 444, so that the fixing rod 442 is disengaged from the fixing hole, and then the sealing cover 44 can be removed, thereby taking out the filter screen 43 for cleaning or replacement, so that the device is convenient for the oil inlet end of the rotating oil cylinder body 3 when in use. The oil that enters is filtered, which improves the practicality and convenience of use. When the disassembly and assembly component 6 is in use, the square connecting block 62 is inserted into the disassembly and assembly seat 61. When the square connecting block 62 moves and abuts against the clamping rod 64, the clamping rod 64 is driven to move up under the action of the guide slide. The clamping rod 64 moves up and drives the clamping slider 65 to move up and compress the clamping spring 66 until the square connecting block 62 moves to the clamping rod 64 and the clamping hole overlap. The clamping spring 66 is reset, driving the clamping rod 64 to insert the clamping hole to fix the square connecting block 62, thereby completing the installation of the oil pipeline 7. When the oil pipeline 7 needs to be replaced after long-term use, the clamping rod 64 is pulled to disengage from the clamping hole, so that the oil pipeline 7 can be removed and replaced. When the device is in use, it is convenient to connect and fix the external oil pipeline 7 with the oil inlet pipe 5 and the oil outlet pipe 8 of the rotating cylinder body 3. At the same time, it is also convenient for the oil pipeline 7 to be quickly replaced when it is damaged after long-term use.
