The sliding assembly 202 includes a sliding shell 2021. The interior of the sliding shell 2021 is provided with a second baffle 2032 that is adapted to the internal size of the oil pressure tank 2031. A baffle 2026 is provided on one side of the first baffle 2026. Two first elastic members 2024 are provided on the middle of the two first elastic members 2024. The mounting shafts provided at the middle of the two first elastic members 2024 slide through the first baffle 2026 and extend into the positioning arm 201. Two second conduits 2028 are provided at the bottom of the sliding housing 2021. The two second conduits 2028 communicate with the sliding housing 2021 and the oil pressure tank 2031. The side of the sliding housing 2021 close to the oil pressure tank 2031 is connected to the first conduit 2027. The first conduit 2027 communicates with the sliding housing 2021. 021 and the oil pressure cabin 2031, the protective component 204 includes a first mounting plate 2041 fixedly connected to the positioning arm 201, and two first sliding rods 2044 sliding through the first mounting plate 2041 are installed on the first mounting plate 2041, and the other ends of the two first sliding rods 2044 are fixedly installed with a second mounting plate 2042, and the outer walls of the two first sliding rods 2044 are respectively provided with a second elastic member 2043, and the two ends of the second elastic member 2043 are fixedly connected to one side of the first mounting plate 2041 and one side of the second mounting plate 2042.

[0034] When the device is working, the user first places the frame seat board to be welded on the top of the table structure 1, and steps on one of the footrests 302 to make it slide in the connecting groove 303. The footrest 302 drives the locking head 2033 to move. When the locking head 2033 moves, it drives the second baffle 2032 connected thereto to move. The movement of the second baffle 2032 pushes the hydraulic oil at the bottom of the oil pressure tank 2031 into the interior of the sliding housing 2021 through the two second conduits 2028. As the hydraulic oil As the pressure increases, the first baffle 2026 is pushed to move. The first baffle 2026 moves to compress the first elastic member 2024.

[0039] When the user needs to continue to fix, the user steps on the footboard 302 hard, so that the footboard 302 drives the locking head 2033 to continue to descend. When the locking head 2033 descends to the inside of the locking shell 3011, the locking head 2033 cooperates with the locking block 3013 to achieve locking. The locking block 3013 is stuck in the annular groove opened in the middle of the locking head 2033. The positioning structure 2 is always in a clamping state.
