The utility model provides a locking device 16 is including moving locking structure and fixed knot structure, it is in to move locking structure setting on the protection casing part 14 that opens and shuts, fixed knot constructs the setting and is in on the protection casing fixed part 13, it accomplishes to move locking structure and fixed knot structure mutually supporting the locking of protection casing.

The dynamic locking structure comprises an upper base plate 1 fixed on the protective cover opening and closing part 14 through a rivet 15, two mounting plates 3 with the same structure and symmetry and a handle 7, wherein the two mounting plates 3 are symmetrically arranged on the upper base plate 1 by taking the center line of the upper base plate 1 as a symmetry axis. The opposite surfaces of the two mounting plates 3 are provided with spring balls 10, the spring balls 10 contract when pressed, and the spring balls 10 rebound rapidly after being loosened.

Handle 7 is "U" style of calligraphy, two support arm top inboard of handle 7 all is provided with arc breach, two the arc breach is the same circle, two support arm top of handle 7 all is provided with the circular slab. The circle centers of the circular plates are provided with pin holes 9, the pin holes 9 are matched with the pins 4 arranged at the centers of the mounting plates 3, and the handles 7 can rotate by taking the pins 4 as axes.

The contact surfaces of the two circular plates and the mounting plate 3 are both provided with inwards-sunken closed spherical clamping grooves 11 and opened spherical clamping grooves 12, the closed spherical clamping grooves 11 of the two circular plates are coaxial, and the opened spherical clamping grooves 12 of the two circular plates are coaxial; the closed spherical clamping groove 11 and the opened spherical clamping groove 12 are matched with the spring ball 10. In a locking state, the handle 7 is vertical, and the spring ball 10 is embedded into the closed spherical clamping groove 11; in the open state, the handle 7 is horizontal, and the spring ball 10 is inserted into the unlocking ball slot 12.

In the embodiment of the present invention, the upper plate 1 is a rectangular plate.

The fixing structure comprises a lower bottom plate 2 fixed on the protective cover fixing part 13 through rivets 15, J-shaped supporting rib plates 8 arranged on the lower bottom plate 2 and spherical fixing devices 5 matched with the arc-shaped gaps, wherein the lower bottom plate 2 corresponds to the upper bottom plate 1 one by one.
