[0030] Embodiment 1

[0031] Such as Figures 1 to 5As shown in the figure, this embodiment proposes an invisible headphone detector, which includes a device main body 1. A servo motor 15 is installed inside the device main body 1. The output end of the servo motor 15 is fixedly connected through a coupling to a coaxial rotating rod 11. A connecting rod 12 is rotatably installed inside the rotating rod 11. A slider 3 is fixedly sleeved on the outer peripheral surface of the connecting rod 12. The slider 3 is slidably sleeved inside the rotating rod 11. A scanning device 10 is installed on the outer peripheral surface of the connecting rod 12. A driven rod 18 is rotatably installed inside the device main body 1. A second bevel gear 20 is fixedly sleeved on the outer peripheral surface of the driven rod 18. A first bevel gear 17 is fixedly sleeved on the outer peripheral surface of the rotating rod 11. The second bevel gear 20 and the first bevel gear 17 are meshed and connected. A connecting rod 21 is rotatably installed inside the device main body. A synchronous belt 19 is sleeved on the outer peripheral surfaces of the connecting rod 21 and the driven rod 18 through a synchronous pulley. A rotating block 22 is fixedly sleeved on the outer peripheral surface of the connecting rod 21. One side of the rotating block 22 is fixedly connected by a screw to a convex block 16. A guiding block 14 is slidably assembled inside the device main body 1. The convex block 16 is slidably assembled inside the guiding block 14. The top of the guiding block 14 is fixedly connected by a screw to a connecting column 23. One side of the connecting column 23 is fixedly connected to a sleeve 24. A clamping block 25 is fixedly sleeved on the outer peripheral surface of the connecting rod 12. A clamping groove 26 is opened inside the sleeve 24. The clamping block 25 is slidably connected inside the clamping groove 26. A plurality of storage racks 9 are arranged in a rectangular array and evenly distributed inside the device main body 1. A pusher 2 is arranged on one side of the device main body 1. Two wheels 7 are installed at the bottom of the device main body 1 and are arranged in a rectangular array and evenly distributed.

[0032] As Figures 1 to 5 shown, a guiding groove 4 is opened inside the guiding block 14. The convex block 16 is slidably connected inside the guiding groove 4.
