The limiting block 6 pushes the locking block 8 and the blocking block 9 to the left, so that the locking block 8 rotates downward around the pin. At the same time, the reverse ratchet structure on the locking block 8 disengages from the ratchet box 7. At this time, the telescopic gate can be released, so that the telescopic gate can continue to extend and retract. The telescopic gate can be locked by reversing the above operation steps, so as to achieve the effect of easy operation.

[0032] In summary, this telescopic gate, by setting up gate 1, lock box 2, box cover 3, moving block 4, pressing block 5, limiting block 6, ratchet box 7, locking block 8, and blocking block 9, solves the problems of the traditional telescopic gate lock box 2 structure having complicated operation steps, excessive operation time, and inability to quickly switch between locked and unlocked states, thus increasing the time required to operate the telescopic gate.
