The longer the length of the detent 24 extends, the more secure the latch is and the less susceptible to external physical factors. The unlocking is only performed by a longer pull-out length, and the operation difficulty is not increased. Meanwhile, in order to avoid the lost of the latch 24 after falling, the latch 24 and the lower lock shell 22 or the upper lock shell 21 may be connected by a rope 242.
While the application has been described in detail with reference to the examples, it will be apparent to those skilled in the art that the foregoing description of the preferred embodiments of the application may be modified or equivalents may be substituted for elements thereof, and that any modifications, equivalents, improvements or changes will fall within the spirit and principles of the application.
