Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present invention, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

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

In this way, the user can conveniently open the upper housing 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 a first fastening assembly, so that the firmness between the upper shell 11 and the lower shell 21 is ensured; the handle 31 is fixed on the lower shell 21 through the second fastening component, so that the firmness of the handle 31 is ensured; and the upper housing 11 is fixed on the lower housing 21 through the handle 31, so that the connection firmness between the upper housing 11 and the lower housing 21 is further improved.

Further, referring to fig. 1 to 4, as an embodiment of the housing 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 body 6 provided on the lower housing 21 for sliding into the first sliding slot 311 and sliding along the first sliding slot 311; one end of the first chute 311 is an inlet 3111, and on a sliding path along which the rod 6 enters from the inlet 3111 of the first chute 311 and slides along the first chute 311, a distance of the sliding path from the pivot 5 gradually decreases. Thus, after the upper housing 11 is covered on the lower housing 21, the rod 6 is first snapped into the inlet 3111 of the first chute 311, and then the handle 31 is turned around the pivot 5, so that the rod 6 can move along the first chute 311; because on the sliding path of the rod body 6 sliding along the first sliding groove 311, the distance between the sliding path and the pivot 5 is reduced, and the distance between the pivot 5 and the rod body 6 is shortened, so that the upper shell 11 can be pressed on the lower shell 21 when the rod body 6 slides along the first sliding groove 311, and the firmness between the lower shell 21 and the upper shell 11 is ensured.

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

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

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

Further, in one embodiment, the number of the first sliding grooves 311 and the rods 6 is two, and the two first sliding grooves 311 and the two rods 6 are in one-to-one correspondence. In this way, the handle 31 rotates more stably due to the cooperation of the two rod bodies 6 and the two first sliding grooves 311.

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

Further, in one embodiment, a reinforcing member 3112 is provided on the handle 31 outside the inlet 3111, and both ends of the reinforcing member 3112 are connected to the handle 31 on both sides of the first chute 311, respectively.
