If unlocking is necessary, the fixture block 361 can be compressed externally to exit the second through hole 42 to release the lock between the connecting piece 4 and the connecting seat 34, and when the fixture block 361 is forced to exit the first through hole 342, the lock between the connecting seat 34 and the first support rod 31 can be released.

[0030] Specifically, a sleeve 43 with a top opening and a bottom opening is provided on one side of the connecting piece 4 close to the pivot connection side, a slot 200 is provided on the upper part of the pivot connection side for the flexible bottom-up insertion of upper end of the sleeve 43, and an insertion column 201 that can extend into the sleeve 43 is provided in the slot 200, the end of the insertion column 201 is connected to a limit seat 202, and a step 431 that is pressed against the limit seat 202 is formed above the limit seat 202 corresponding to the inner wall of the sleeve 43, the door railing body 1 can perform vertical reciprocating motion relative to the connecting piece 4 to make the limit seat 202 contact or move away from the step 431.

[0033] Specifically, V-shaped first limit position 432 and a second limit position 433 are annularly spaced on the upper end of the sleeve 43, the depth of the second limit position 433 is less than that of the first limit position 432, and the inner wall of the slot 200 is provided with a latch 205 that fits the first limit position 432, the latch 205 can, with the swing of the door barrier body 1, move between the position where it is aligned with the first limit position 432 and the position where it is aligned with the second limit position 433, and can snap into or exit the first limit position 432 or partially snap into or exit the second limit position 433 along with the vertical reciprocating motion of door railing body 1, and a first top spring 206 is also provided and is sleeved on the insertion column 201, and the two ends of the first top spring 206 are elastically pressed against the step 431 and limit seat 202, and the first top spring 206 can apply downward force to the door railing body 1. When the latch 205 is located at the first limit position 432, the door railing body 1 is in the closed position and, during the process of door opening, it is necessary to first release the lock mechanism 2, lift the door railing body 1, and then swing the door railing body 1, for example, swing the door railing body 1 90 to align the latch 205 with the second limit position 433, and release the door railing body 1 to let it fall, so that the latch 205 can partially engage with the second limit position 433 for limit purpose, maintaining the door railing body 1 at open position for a long time. For door closing, due to the shallow depth of the second limit position 433, the door railing body 1 can be directly swung to move upwards through the fitness between the latch 205 and the V-shaped structure of second limit position 433, causing the latch 205 to detach from the second limit position 433 and then, the elastic force applied by the first top spring 206, in combination with the latch 205 and the V-shaped structure of the first card position 432, can make the latch 205 quickly engage in the first limit position 432, so that the operator can allow the door railing body 1 automatically swing to close the door by slightly swinging the door railing body 1.
