The handle can be opened under the locking condition, and is operated through the button structure 402a and the rotating member 403a, and the rotating member is adjusted to the opening position at the locking symbol position, namely, the blocking piece structure 403b below the rotating member is loosened, and then the button structure 402a is pressed down, so that the handle can be automatically sprung open to 90 degrees (as shown in fig. 5).

The lock body handle can be sprung open, because the bottom is provided with a long spring, one end of the spring is pressed on the plug 502, the other end of the spring is pressed on the rack (the driving main body 301) to form a double-end press, the plug slides in during the installation of the lock body, and the spring is pressed outwards; when the handle is unlocked, the spring pushes the rack movement mechanism to press inwards, so that a bidirectional force effect is achieved, and the dual-purpose function of the spring is skillfully realized by the application.

According to the utility model, the plug is installed in a buckle manner, two ends are clamped into a section groove and clamped on a section, then the locking and opening of the rotating piece 403a are performed to control the action of a button (button structure 402 a), and when the button is pressed down, the handle automatically bounces to 90 degrees and automatically drives the lock tongue to retract to 90 degrees; i.e. open, whereas the opposite locking tab is locked.

The technical scheme of this application mainly shows following technical advantage and effect:

1. compared with the prior art, under the handle locking state, the spring bolt of this application can carry out direct switching-over through stirring 180 degrees clockwise, and it is convenient to adjust, solves the inconvenient problem of loose screw switching-over re-tightening screw.

2. Compared with the prior art, the spring realizes the bidirectional force action through the spring, realizes the action of the linkage force to the handle, the driving main body 301, the transmission gear 14, the lock tongue and the plug, installs the thrust action on the plug), and utilizes the spring double-purpose to reasonably use the space on the product.

3. Compared with the prior art, the mounting mode of the utility model adopts a buckle mode, which simplifies the mounting and dismounting, saves the mounting time, etc

4. Compared with the prior art, the rotating piece of the child lock plays a role in the child lock.
