DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Embodiment 1, by Figure 1-Figure 5The utility model comprises a first shell 1 and a second shell 2 which are butted against each other, the first shell 1 and the second shell 2 are connected by bolts 3, one side of the first shell 1 and the second shell 2 is clamped with an end cover 4, the first shell 1 and the second shell 2 are internally slidably connected with a lock tongue 5, one end of the lock tongue 5 is provided with a card interface 6, and the side of the lock tongue 5 away from the card interface 6 is provided with a toggle groove 7;

[0025] A rotating rod 8 is inserted into one end of the first housing 1, a knob 9 is fixedly connected to one end of the rotating rod 8, a rotating block 10 is connected to the other end of the rotating rod 8, a lever 11 is penetrated and connected to one end of the rotating block 10, and the lever 11 is located in the toggle slot 7;

[0026] The first housing 1 has four internal corners connected to positioning columns 12, the second housing 2 has four internal corners connected to connecting columns 13, and the bolts 3 pass through the positioning columns 12 and are connected to the connecting columns 13;

[0027] Slide plates 14 are connected to the upper and lower sides of the first shell 1 and the second shell 2, and slide grooves 15 are provided on the upper and lower sides of the lock tongue 5, and the slide grooves 15 are slidably connected to the slide plates 14;

[0028] Buckles 16 are connected to both ends of the upper and lower parts of the inner side of the end cover 4, and slots 17 are provided at the upper and lower parts of the inner walls of the first shell 1 and the second shell 2 near the edge, and the buckles 16 are engaged with the slots 17;
