Locking structure between conveying line bodies

The locking structure comprises a clamping mechanism arranged on a first conveying line body and a butt joint mechanism arranged on a second conveying line body, the clamping mechanism and the butt joint mechanism are oppositely arranged on a lower end cross beam at the butt joint position of the first conveying line body and the second conveying line body, and the clamping mechanism and the butt joint mechanism can be in butt joint in a clamped mode. The automatic locking and stopping device has the advantages that locking and butt joint of the clamping mechanism and the butt joint mechanism can be controlled through pulling, the mechanism is simple, butt joint is accurate, the clamping state can be conveniently switched at any time, and the automatic locking and stopping device is convenient to use and high in practicability. Upper-layer space is not occupied, automatic releasing and stopping are completed through a mechanical mechanism, and cost is saved. 本申请公开了一种输送线体间锁定结构，包括设置于第一输送线体的卡和机构和设置于第二输送线体的对接机构，卡
