Through the movable plate 16 drives the fastening plate 17 to move forwards, the front end of the fastening plate 17 is used for tightening the fastening belt 11, and the situation that the movable plate 16 cannot excessively move forwards to tighten the fastening belt 11 due to the length limitation of the guide groove 23 is avoided, and finally the plugging effect is influenced.

Specifically, elastic connection piece 13 is hollow round platform form, elastic connection piece 13 is fixed cup joint the lower extreme outside of casing 1, elastic connection piece 13's the outside is equipped with annular groove 18, elastic connection piece 6 passes through annular groove 18 and the last cable outlet hole joint of cubical switchboard. The plugging device is pressed in the cable outlet hole, so that the elastic connecting piece 13 deforms, the inner side edge of the cable outlet hole in the switch cabinet is extruded into the annular groove 18 to be clamped, and the plugging device and the switch cabinet are connected and mounted. The side face of the elastic connecting piece 13 is obliquely arranged, so that the installation convenience is enhanced. But the clamping position is a horizontal clamping surface, so that the edge of the cable outlet hole can be separated from the annular groove 18 only by applying a larger acting force, and the situation that the plugging device is pushed and arched open by small animals such as rats can be effectively avoided.

Concrete, still including recording play device 19, megaphone 20, infrared sensor 21, megaphone 20 recording play device 19 is located on hold the inside of chamber 3, infrared sensor 21 is located hold the inside of chamber 4 down, recording play device 19 with megaphone 20 electricity is connected, controlling means respectively with recording play device 19, infrared sensor 21 electricity are connected. The infrared sensor 21 detects conditions in the lower accommodating cavity 4, and if a mouse is detected to approach, signals can be transmitted to the controller 7, the controller 7 controls the recording and playing device 19 to be started, the prestored cat sound or mouse sound is played, and the sound is amplified through the loudspeaker 20, so that the deterrent effect on the mouse is further enhanced, and the mouse is prevented from approaching.

Specifically, a person skilled in the art may select common models of the controller 7, the micro motor 8, the pressure sensor 15, and the infrared sensor 21 to implement the present embodiment, and the corresponding connection manner is also a connection manner commonly used by the person skilled in the art, and is not specifically described in the present embodiment.
