[0036] Furthermore, the limiting member 54 includes a limiting rod 541 for connecting the various components. A wedge block 542 is fixedly connected to the left side of the limiting rod 541, and its inclined surface is compatible with the semicircular block 536 and the inclined ring 535. A mounting groove 521 is provided in the middle of the fixed block 52 for cooperating with the connection of the mounting member 53. An auxiliary groove 522 is provided in the middle of the right side of the mounting groove 521 for cooperating with the contraction and movement of the wedge block 542, and the wedge block 542 is movably connected thereto. A control groove 523 is provided on the right side of the auxiliary groove 522 for cooperating with the connection of the No. 3 spring 543. The No. 3 spring 543 is fixedly connected between the control groove 523 and the wedge block 542. A limiting groove 524 is provided on the right side of the control groove 523 for cooperating with the movement of the limiting rod 541, and the limiting rod 541 is slidably connected thereto.

[0037] Working principle: When the shell 1 and the cover 2 need to be installed together, the cover 2 is inserted between the four positioning plates 4, and then pressed downward to insert the convex ring 21 into the groove 11. At the same time, when the cover 2 moves, it will drive the mounting block 51 connected thereto to move downward together, and the mounting piece 53 connected to the mounting block 51 will also move downward together, and its lower part will be inserted into the mounting groove 521. When the semicircular block 536 contacts the wedge block 542, it will push the wedge block 542 to move into the auxiliary groove 522. At the same time, the limiting rod 541 will slide into the limiting groove 524, and the wedge block 542 will squeeze the No. 3 spring 543. When the mounting block 51 contacts the fixing block 52, the semicircular block 536 will move down to the limit. At the same time, the wedge block 542 will lose the pressure exerted by the semicircular block 536. The No. 3 spring 543 will push the wedge block 542 to reset, so that it is stuck on the upper part of the semicircular block 536, so that it limits the mounting piece 53, connects the mounting block 51 with the fixing block 52, and then presses the left and right flaps 33 downward and inward. Since the flaps 33 have a certain deformation ability, they will undergo slight deformation. At the same time, the No. 2 convex strip 34 will be stuck on the inner side of the No. 1 convex strip 13, so that the flaps 33 are connected to the shell 1, so that the cover body 2 and the shell 1 are fixed.

[0038] When it is necessary to separate the shell 1 from the cover 2, the two latches 33 are pulled outward and upward to drive the second protrusion 34 to break away from the restriction of the first protrusion 13, and then the control rod 531 is pressed downward. The control rod 531 will drive the circular plate 532 connected thereto to move downward and squeeze the first spring 533. At the same time, the limit ring 534 connected thereto will also move downward and push the inclined ring 535 at its lower part to move downward. Since the inclined ring 535 has two inclined surfaces, the inclined surface at the lower part will push the wedge block 542 to move into the auxiliary groove 522 again. When the inclined ring 535 continues to move downward, the wedge block 542 will lose the thrust of the inclined ring 535, and the third spring 543 will push the wedge block 542 to reset. At this time, the wedge block 542 The upper part of the bevel ring 535 will be located, and then the cover body 2 will be pulled upward, and the cover body 2 will drive the mounting block 51 and the mounting member 53 connected thereto to move upward. When the mounting member 53 moves upward, the wedge block 542 will push the bevel ring 535 to move into the receiving groove 538, and the bevel ring 535 will squeeze the No. 2 spring 537. When the bevel ring 535 is completely pressed into the receiving groove 538, since the cover body 2 continues to move upward, the driven semicircular block 536 will drive the bevel ring 535 to move upward together, and the wedge block 542 will follow the upper bevel of the bevel ring 535 and retract into the auxiliary groove 522 again. The bevel ring 535 and the semicircular block 536 will lose the restriction of the wedge block 542, thereby breaking away from the mounting groove 521, so that the cover body 2 is separated from the shell 1.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
