As shown in Fig. 2, safety pole 50 has limit recess portion 51, by making the lock core 42 of lock body component 40 in its own weight Power effect under protrude into limit recess portion 51 in and with limit 51 limit stops of recess portion, be in the lock state lock body component 40.In this way, Above-mentioned setting improves the reliability of the limit stops between safety pole 50 and lock core 42, guarantees that safety pole 50 can sufficiently be locked It is fixed.

As shown in Fig. 2, limit recess portion 51 be it is multiple, multiple limit recess portions 51 are set along the extending direction interval of safety pole 50 It sets.

It can be seen from the above description that the above embodiments of the present invention realized the following chievements:

When staff surprisingly pulls open door body, door body drives adjustment structure motion, so that first connecting rod is along its height side It is detached from cooperation to decline and with lock core, so that lock core is protruded into via hole under its own gravity to stop with safety pole limit Gear, lock body component are switched to lock state by unlocked state, and safety pole is locked, then staff can not carry out safety pole Operation, the mode transfer template connecting with safety pole are also at lock state, then clamping can not continue to run, and avoid clapper die spotting press Structure crushes staff, and then solves the problems, such as that there are security risks due to safety is poor for clamping in the prior art. When door body is closed, door body drives adjustment structure motion, so that first connecting rod rises along its short transverse and carries out to lock core Jacking, so that lock core is exited to outside via hole, lock body component is switched to unlocked state by lock state, and safety pole can continue to transport Row, so that clamping being capable of normal use.
