Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Referring now to fig. 1-4, a housing fastening system according to the present invention will now be described. The shell fastening system comprises a lower shell 21, an upper shell 11 detachably covered on the lower shell 21, and a handle 31 pivoted on the upper shell 11 through a pivot 5; a first fastening component for fixing the upper shell 11 on the lower shell 21 is arranged between the upper shell 11 and the lower shell 21; a second fastening member for fixing the handle 31 to the lower case 21 is provided between the handle 31 and the lower case 21.

In this manner, the user can conveniently open the upper case 11 by holding the handle 31; after the upper shell 11 and the lower shell 21 are closed, the upper shell 11 is fixed on the lower shell 21 through the first fastening assembly, so that the firmness between the upper shell 11 and the lower shell 21 is guaranteed; then, the handle 31 is fixed on the lower shell 21 through the second fastening component, so that the firmness of the handle 31 is guaranteed; and the upper shell 11 is fixed on the lower shell 21 through the handle 31, so that the firmness of connection between the upper shell 11 and the lower shell 21 is further improved.

Further, referring to fig. 1 to 4, as an embodiment of the shell fastening system provided by the present invention, the first fastening assembly includes a first sliding slot 311 formed on the handle 31 and a rod 6 disposed on the lower shell 21 and adapted to slide into the first sliding slot 311 and slide along the first sliding slot 311; one end of the first sliding slot 311 is an entrance 3111, and on a sliding path along which the rod 6 enters from the entrance 3111 of the first sliding slot 311 and slides along the first sliding slot 311, a distance from the pivot 5 is gradually reduced. Thus, after the upper housing 11 is covered on the lower housing 21, the rod 6 is first inserted into the inlet 3111 of the first sliding slot 311, and then the handle 31 is rotated around the pivot 5, so that the rod 6 can move along the first sliding slot 311; because on the body of rod 6 along the gliding sliding path of first spout 311, the distance of sliding path and pivot 5 reduces, has shortened the distance between pivot 5 and the body of rod 6 for body of rod 6 can compress tightly last casing 11 on lower casing 21 when sliding along first spout 311, has ensured the fastness between lower casing 21 and the last casing 11.

Further, referring to fig. 1 to 4, as an embodiment of the housing fastening system provided by the present invention, the first sliding slot 311 is a strip-shaped hole formed on the handle 31. So, the bar hole is easy to produce, and the body of rod 6 slides along the bar hole easily.

Further, referring to fig. 1 to 4, as an embodiment of the shell fastening system provided by the present invention, a concave portion protruding toward the pivot 5 and allowing the rod 6 to be clamped is provided on an inner wall of the first sliding slot 311. Therefore, when the rod body 6 is clamped into the concave part, the rod body 6 can be positioned in the concave part, and the rod body 6 is prevented from sliding out along the first sliding groove 311; in addition, when the rod body 6 is clamped into the concave part, the rod body 6 impacts the concave part to generate sound, and a user can judge whether the rod body 6 is clamped or not through the sound.

Further, in one embodiment, the sliding path is arcuate. Thus, the rod 6 slides more stably along the first sliding slot 311.

Further, in one embodiment, the number of the first sliding grooves 311 and the number of the rods 6 are two, and the two first sliding grooves 311 and the two rods 6 correspond to each other one by one. So, the cooperation of two body of rod 6 and two first spouts 311, handle 31 rotates more stably.

Further, in one embodiment, two rods 6 are located at opposite ends of the upper housing 11. In this way, the lever bodies 6 respectively located at the opposite ends of the upper case 11 can be more balanced when the handle 31 is rotated.

Further, in one embodiment, a reinforcement 3112 is disposed on the handle 31 outside the entrance 3111, and both ends of the reinforcement 3112 are respectively connected to the handle 31 on both sides of the first chute 311. Thus, the reinforcement 3112 can reduce deformation at the entrance 3111 of the first chute 311.
