The lower connecting frame 24 slides in the second clamping groove 35, so that the connecting frame can adjust the length in time and stabilize the supporting leg when the connecting frame keeps the limit of the supporting leg to prevent the supporting leg from sideways. By rotating the pedal rod 37, the pedal rod 37 is kept perpendicular to the supporting chassis 9, and is supported by the bottom of the supporting chassis 9, so that the pedal rod 37 passes through the bottom of the supporting chassis 9 and the second mounting block 23. The position limit is convenient for the staff to apply pressure on the pedal rod 37, and then it is convenient for the support bottom cone 10 to be pierced into the supported ground, so as to quickly and flexibly adjust the support of the support legs, and quickly and flexibly level the support plate 1 , by passing the middle of the double-ended spring rod 39 through the limit hole 44 of the support chassis 7 and the support bottom cone 10, then move the C-shaped limit frame 40 to both sides at the same time, and rotate the C-shaped limit frame 40 until the C-shaped limit The limit frame 40 is vertical, and then the C-shaped limit frame 40 is moved downward to make the limit post 43 abut the upper end of the limit chute 41, so that the C-shaped limit frame 40 is kept in contact with the support chassis 7 , so that the positioning member 33 maintains the connection between the supporting chassis 7 and the supporting bottom cone 10. When supporting on a smooth ground is required, the supporting chassis 7 is moved downward so that the lower end of the supporting bottom cone 10 does not contact the ground. The frictional force on the surface makes the support legs sway stably. When it needs to be supported in the mud, the support chassis 7 is moved up, and the lower end tip of the support bottom cone 10 leaks out, so that the lower end of the support bottom cone 10 is used as the pile foundation. And through the support chassis 7 for double support, so as to ensure stability, and can be quickly disassembled and assembled to improve the use efficiency.
