In the embodiment shown in fig. 1, the first fastening holes 22 of the case cover 2 mounted on the upper portion of the middle case 1 and the first fastening holes 22 of the case cover 2 mounted on the lower portion of the middle case 1 are oppositely arranged, and when assembling, the case cover 2 is pre-positioned on the upper portion and the lower portion of the middle case 1 by the cooperation of the first concave-convex limiting part 11 and the second concave-convex limiting part 21, and then the case cover 2 can be fastened on the upper portion and the lower portion of the middle case 1 by passing screws through the two oppositely arranged first fastening holes 22. The shell cover 2 can be prevented from being loosened due to offset in the vertical direction and the horizontal direction relative to the middle shell 1 through the matching of the first concave-convex limiting part 11 and the second concave-convex limiting part 21 and the matching of the two first fastening holes 22. In the embodiment shown in fig. 2 and 3, the circumferential side wall of the middle housing 1 is provided with a first mounting hole 12, and the first fastening hole 22 faces the first mounting hole 12, when assembling, firstly, the housing cover 2 is pre-positioned at the upper part and the lower part of the middle housing 1 respectively by the cooperation of the first concave-convex limiting part 11 and the second concave-convex limiting part 21, and then the housing cover 2 can be locked at the upper part and the lower part of the middle housing 1 respectively by a screw passing through the first fastening hole 22 and the first mounting hole 12.

In the embodiment shown in fig. 2, the upper mounting portion 131 and the first concave-convex limiting piece 11 are alternately disposed on the upper portion of the circumferential sidewall of the middle housing 1, so that the fixing force formed between the upper mounting portion 131 and the first fastening hole 22 of the housing cover 2 and the fixing force formed between the first concave-convex limiting piece 11 and the second concave-convex limiting piece 21 can be staggered with each other, so that the two fixing forces can be uniformly distributed; the lower mounting portion 132 and the first concave-convex limiting piece 11 are alternately arranged at the lower part of the circumferential side wall of the middle case 1, so that the fixing force formed between the lower mounting portion 132 and the first fastening hole 22 of the case cover 2 and the fixing force formed between the first concave-convex limiting piece 11 and the second concave-convex limiting piece 21 can be mutually staggered, and the two fixing forces can be uniformly distributed; the first concave-convex limiting part 11 arranged on the upper part of the circumferential side wall of the middle case 1 and the first concave-convex limiting part 11 arranged on the lower part of the circumferential side wall of the middle case 1 are arranged in a staggered manner, so that the fixing force between the first concave-convex limiting part 11 arranged on the upper part of the circumferential side wall of the middle case 1 and the corresponding second concave-convex limiting part 21 and the fixing force between the first concave-convex limiting part 11 arranged on the lower part of the circumferential side wall of the middle case 1 and the corresponding second concave-convex limiting part 21 can be staggered with each other, and the two fixing forces can be uniformly distributed; the upper mounting part 131 and the lower mounting part 132 are arranged in a staggered manner, so that the fixing force formed between the upper mounting part 131 and the corresponding first fastening hole 22 of the shell cover 2 and the fixing force formed between the lower mounting part 132 and the corresponding first fastening hole 22 of the shell cover 2 can be staggered, so that the two fixing forces can be uniformly distributed, and the shell cover 2 and the middle shell 1 can be mounted more stably.
Specifically, the number of the upper mounting portions 131 and the number of the lower mounting portions 132 are four, and when the number of the upper mounting portions 131 or the number of the lower mounting portions 132 is less than four, the fixing force of the housing cover 2 between the middle housing 1 is not enough to fix the housing cover 2 to the middle housing 1, so that the housing cover 2 is easy to be loosened and even fall off cheaply during use; when the number of the upper mounting parts 131 or the number of the lower mounting parts 132 is more than four, more material is required to mold the upper mounting parts 131 or the lower mounting parts 132, thereby increasing the production cost.
Preferably, the first fastening holes 22 are formed in a circumferential side surface 24 of the housing cover 2, the first fastening holes 22 vertically penetrate the circumferential side surface 24 of the housing cover 2, and the first mounting holes 12 vertically penetrate a circumferential side wall of the middle cabinet 1.
