The invention discloses a folder which comprises a first connecting shell, a second connecting shell, a first locking safety mechanism and a second locking safety mechanism. The first connecting shell and the second connecting shell are hinged to each other; the second locking safety mechanism comprises a locking handle and a second locking assembly arranged on the locking handle. The locking handle is hinged to the first connecting shell. The folder has the beneficial effects that under the normal condition, the locking handle is located at the first position, the two locking safety mechanisms can play a role, when the second locking safety mechanism cannot play a role accidentally, the locking handle is loosened, namely the locking handle is located at the second position, the first locking safety mechanism can still play a role, and when the folding device needs to be opened, the locking handle is located at the third position, the two locking safety mechanisms are unlocked.

    本发明公开了一种折叠器,包括:第一连接壳体、第二连接壳体、第一锁止保险机构和第二锁止保险机构;所述第一连接壳体和所述第二连接壳体两者互相铰接;所述第二锁止保险机构包括锁紧手柄和设置在所述锁紧手柄上的第二锁定组件;所述锁紧手柄和所述第一连接壳体铰接。本发明的有益效果:通常情况下,锁紧手柄处于第一位置,两个锁止保险机构都能发挥作用,当不小心第二锁止保险机构不能发挥作用,锁紧手柄松动即锁紧手柄处于第二位置,第一锁止保险机构还能发挥作用,当需要打开折叠器时,锁紧手柄处于第三位置,两个锁止保险机构都解锁。
