Part 321 fits the connection. The structure and working principle of the indicator device of the present invention will be described in detail below in conjunction with FIG. 2 .

Fig. 2 is an exploded view of the structure of the indicator device of Embodiment 1 of the present utility model; Referring to Fig. 2, the indicator device includes a circuit board 600, a dome 500, a closed strip-shaped elastic body 200, a magnet 400, a rocker 300 and base 100. The circuit board 600 has a magnetic position sensor for detecting the moving direction and position of the magnet. The circuit board 600 includes a rigid printed circuit board, a flexible printed circuit board, and an adapter located at one end of the flexible circuit board, so that the indicator device of the present invention has good applicability. The base 100 is assembled on the rigid printed circuit board of the circuit board 600 through snap fit, which is convenient for disassembly and assembly. The dome 500 is located in the space formed by the base 100 and the circuit board 600 , and is facing the rocker 300 . The magnet 400 is located inside the rocker 300 . The base 100 has a base hole 111 and an elastic body stop mechanism 112 arranged around the base hole 111. The rocker 300 has a rocker detail 310, a rocker thick portion 320 located at the lower end of the rocker detail 310, and a rocker thick portion 320 disposed on the rocker thick The ear portion 321 on the peripheral wall of the portion 320. When assembling, first assemble the closed strip-shaped elastic body 200 on the elastic body limit mechanism 112 to form a polygon, and the inscribed circle of the polygon is the circumference of the rocker thick part 320 of the rocker 300; then the rocker The ear part 321 of 300 is fixed to the thick part 320 of the rocker, so that the strip-shaped elastic body passes through the through hole formed between the ear part 321 and the thick part 320 of the rocker; at this time, the thin part 310 of the rocker is exposed through the hole 111 of the base to the outside of the base 100; then assemble the magnet 400 from the bottom of the rocker 300 to the thick part 320 of the rocker; finally snap the base 100 and the circuit board 600 into place to form an indicator device. The utility model preferably further includes a cap, which is connected with the other end of the rocker detail 310 and covers the base hole 111 . the

When the indicator device of this embodiment is connected to the smart device, the user touches the cap with the finger, and the cap moves in the direction of the force of the finger. Since the cap is fixedly connected with the rocker 300, the rocker 300 produces the same movement as the cap, and then drives The magnet 400 also produces the same movement, and the magnetic position sensor located on the circuit board 600 detects the movement of the magnet 400, and transmits the signal to the processing unit through the circuit board 600, and the processing unit can obtain the operation instruction signal of the finger after processing. The movement of the rocker 300 will deform the strip-shaped elastic body 200 to generate a certain elastic force (a certain resistance relative to the finger), and when the force of the finger disappears, the elastic force will make the rocker 300 return to its original position. Since the strip-shaped elastic body 200 is connected with the elastic body limiting mechanism 112 and the rocker 300, it is ensured that the rocker 300 can move in any direction in the plane and then reset, that is, the universal navigation function is realized. When a click operation is required, press the cap with your hand, and then the rocker 300 will press the dome 500, and the dome 500 will move downward under force, causing deformation, and the strip elastic body 200 will also deform. The click signal is transmitted to the processing unit through the circuit board 600, and the processing unit can obtain the click operation instruction signal after processing. When the pressing force disappears, the rocker 300 will reset under the action of the elastic force. the
