DETAILED DESCRIPTION

[0019] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used to explain the utility model and are not used to limit the scope of the utility model.

[0020] As Figs. 1-3 shown, a four-jaw joint structure includes detachably connected four-jaw joint 1 and top disc 2, the four-jaw joint 1 is symmetrically provided with slidingly connected sleeve pipe 3 on the outside of the included angle, and the sleeve pipe 3 is provided with pressing handle 4. Telescopic supporting rod 6 and pull rod 7 are connected with top disc 2, telescopic supporting rod 6 is used for adjusting height, pull rod 7 cooperates with telescopic supporting rod 6 to stretch out and draw back, the top end and the bottom end of telescopic supporting rod 6 are connected with top disc 2, the bottom end of top disc 2 is provided with adjusting supporting leg 5 below and is suitable for adjusting multiple heights, top disc 2 is used for the detachable connection of telescopic supporting rod 6 and pull rod 7 of telescopic operation platform, four-jaw joint 1 is detachably connected with top disc 2, pressing handle 4 can quickly install or disassemble the installation platform, save time and labor, and improve the production efficiency. Through the four-jaw joint 1, the top disc 2, the sleeve pipe 3 and the pressing handle 4, different operation heights and ranges can be adapted.

[0021] The four-jaw joint 1 comprises a body 11, the body 11 is provided with a sleeve 13 for sliding connection of the sleeve 3, the sleeve 13 is fixedly connected with the body 11 through a claw 12. The sleeve 13 on the outside of the symmetrical included angle is used for adjusting the position of the sleeve 3 on the pressing handle 4. When the claw 12 is upward, the connecting wood strip can be placed between the two claws 12 on the side, the height of the sleeve 13 and the claw 12 is consistent with the thickness of the connecting wood strip, the distance between the two claws 12 on the side is the width of the connecting wood strip, the free end surface (i.e. the top surface) of the sleeve 13 and the claw 12 and the top surface of the connecting wood strip are connected with the mounting platform, which is convenient for use in various application scenarios. When the claw 12 is downward, the connecting end surface of the body 11 and the sleeve 13 and the claw 12 is upward, and the connecting end surface is connected with the mounting platform.

[0022] The body 11 is provided with a plurality of bottom fixing holes 14, and the bottom fixing holes 14 are arranged in an annular array around the body 11. The bottom fixing hole 14 is used for fixing the top disc 2 or the mounting platform.
