As a further solution of the present invention: the elastic force of the spring 19 presses the contact block 6 downward, so that the contact block 6 always fits the displacement surface, causing the sensor 22 on the first telescopic rod 7 to move downward simultaneously, and the receiving panel 23 The received information is transmitted to the internal equipment of the work box 17. When the data is too large, the alarm light 4 on the upper surface of the housing 3 lights up and alarms. When the displacement is sideways, the contact block 6 is displaced synchronously, driving the first telescopic rod 7 Move synchronously, so that the guide rod 18 drives the slider 20 to slide in the first chute 21. The first telescopic rod 7 slides on the surface of the rotating rod 14 through the second chute 24. Similarly, the sensor 22 moves synchronously. In the same way, the receiving panel 23 receives the displacement information and transmits it to the equipment on the inner wall of the work box 17. If the data is too large, the alarm light 4 lights up. When lateral displacement occurs, the contact block 6 rotates, causing the first telescopic rod 7 to rotate, causing the rotating rod 14 to rotate. Sliding and rotating on the annular slide rod 16 through the inner hole 15 causes the sensor 22 to rotate around the first telescopic rod 7 so that the receiving panel 23 receives information for transmission. When the length of the second chute 24 needs to be adjusted, remove the second telescopic rod. 9. Replace the second telescopic rod 9 with the required length, clamp the first limiting block 10 at the lower end of the second telescopic rod 9 into the first limiting groove 8, and then clamp the second limiting block 13 into the first limiting groove 8.

Working principle: The lower surface of the contact block 6 fits the displacement surface. The contact block 6 is connected to the thread 1 at the lower end of the first telescopic rod 7 through the internal thread, and then locked by the lock nut 2. When the displacement shrinks, the contact block 6 receives The elastic force of the spring 19 presses the contact block 6 downward, so that the contact block 6 always fits the displacement surface, causing the sensor 22 on the first telescopic rod 7 to move downward synchronously, and the receiving panel 23 receives the information and transmits it to the work box 17 Internal equipment, when the data is too large, the alarm light 4 on the upper surface of the housing 3 lights up and gives an alarm. When it is displaced laterally, the contact block 6 is displaced synchronously, driving the first telescopic rod 7 to move synchronously, causing the guide rod 18 to drive the slider. The block 20 slides in the first chute 21, and the first telescopic rod 7 slides on the surface of the rotating rod 14 through the second chute 24. In the same way, the sensor 22 moves synchronously. In the same way, the receiving panel 23 receives the displacement information and passes it to the work box. 17 Inner wall equipment, if the data is too large, the alarm light 4 will light up. When the displacement is distorted, the contact block 6 will rotate, causing the first telescopic rod 7 to rotate, so that the rotating rod 14 passes through the inner hole 15 and is on the annular sliding rod 16 The sliding rotation causes the sensor 22 to rotate around the first telescopic rod 7 so that the receiving panel 23 receives the information and transmits it. When the length of the second chute 24 needs to be adjusted, remove the second telescopic rod 9 and replace it with the second telescopic rod 9 of the required length. Use the second telescopic rod 9 to clamp the first limiting block 10 at the lower end of the second telescopic rod 9 into the first limiting groove 8, and then clamp the second limiting block 13 into the second limiting groove 11.
