DETAILED DESCRIPTION

[0025] See also Figure 1-6 The utility model provides a technical solution: a high-precision sensor structure triggered in six directions, including a main body, wherein the main body includes a circuit board 10, a fixed positioning cover 20 and a movable claw 4, the circuit board 10 is fixedly mounted on the top of the main body, the fixed positioning cover 20 is fixedly mounted on the bottom of the main body, the movable claw 4 is slidably mounted on the central axis of the fixed positioning cover 20, three groups of positioning components are arranged between the fixed positioning cover 20 and the movable claw 4, each group of positioning components and the circuit board 10 form a feedback power supply circuit, each group of positioning components includes two positioning conductive balls 44, a positioning conductive rod 41, two cover conductive rods 23 and two conductive probes 11, the conductive probe 11 is vertically fixed on the bottom of the circuit board 10, the positioning conductive rod 41 is fixed to the side wall of the movable claw 4, and the outer end of the positioning conductive rod 41 is slidably supported on the fixed positioning cover 20. At the top of the fixed positioning cover 20, the two cover conductive rods 23 are slidably clamped on the top of the fixed positioning cover 20 and located on both sides of the positioning conductive rod 41, the conductive probe 11 is located directly above the cover conductive rod 23 and the bottom of the conductive probe 11 is conductively and slidably connected with the cover conductive rod 23 at the corresponding position, the top of the movable claw 4 is provided with a movable positioning ring seat 42, the top of the movable claw 4 and the inner bottom of the movable positioning ring seat 42 are respectively provided with magnets that attract each other, and a magnetic sensor for detecting the attraction force of the magnet is provided at the magnet position, the movable positioning ring seat 42 is pressed on the top of the movable claw 4 by a spring 46, and a pressure sensor is provided on the top of the spring 46, the positioning conductive ball 44 is slidably clamped on the bottom of the movable positioning ring seat 42, and the two positioning conductive balls 44 are respectively provided on the left and right sides of the positioning conductive rod 41;

[0026] During operation, when the movable claw 4 is not pushed by external force, Figure 5As shown, the bottom of the conductive probe 11 on one side of a set of positioning components is in conductive contact with the cover conductive rod 23, the cover conductive rod 23 is in conductive contact with the positioning conductive rod 41 through the positioning conductive ball 44, and the positioning conductive rod 41 is in conductive contact with the conductive probe 11 on the other side through the cover conductive rod 23 on the other side. Then, the tops of the two conductive probes 11 are connected on the circuit board 10, forming a feedback power loop. When the movable claw 4 is subjected to force, the positioning conductive rod 41 on the force-bearing side is lifted up, and the positioning conductive balls 44 on both sides of the positioning conductive rod 41 are no longer connected with the cover conductive rod 23, and the feedback power loop is de-energized. Therefore, when the XY direction is triggered, the movable claw 4 will trigger the positioning component to change, and the feedback power circuit of the corresponding position will change, thereby realizing the feedback of the contact signal.

[0033] The bottom of the fixed positioning cover 20 is covered with a bottom cover plate 24. The axis of the fixed positioning cover 20 and the bottom cover plate 24 are both provided with a penetration opening for slidingly passing the movable claw 4.
