The pin shaft can be provided with fixing holes at two ends, and the two sides are connected with the ladder stand body 11 and the supporting seat 12 through the clamping pieces, so that the pin shaft is prevented from being clamped in the round hole 1211 when the ladder stand body 11 and the supporting seat 12 are disassembled. The same pin shaft and the same supporting seat 12 are arranged at the corresponding position of the vertical rod 111 at the other side.

As a specific solution, the limit stop 15 is disposed on the supporting base 12, and the limit stop 15 is fixedly connected between the two upright plates 121. The limit stop 15 includes a flat plate portion 151 and a bending portion 152, wherein both sides of the flat plate portion 151 are fixedly connected with the two vertical plates 121, and the bending portion 152 is fixedly connected with one end of the flat plate portion 151 close to the circular hole 1211. Two sides of the flat plate portion 151 are fixedly connected to the two vertical plates 121, wherein the fixed connection is welding, and one end of the flat plate portion 151 is fixedly connected to the bending portion 152.
