First, it should be noted that, during the measurement of the surface to be measured, since the probe 10, the actuator, the chip 30 and the memory 40 are all continuously operated to continuously generate the measurement values, the current measurement values are continuously changed, and the maximum measurement values and the minimum measurement values may be changed. For example, at the time of measurement to the 5 th second, the current measurement value is 1, the maximum measurement value is 3, and the minimum measurement value is-2, and at the time of measurement to the 10 th second, the current measurement value is 2, the maximum measurement value is 5, and the minimum measurement value is-4.
Secondly, in the above embodiment, the first measurement value converted by the chip 30 according to the electrical signal is stored, and the measurement value may be stored in the memory 40 or other storage units, which is not limited by the present invention.
In one embodiment, the chip 30 may compare the converted measurement values with the first measurement value to generate a maximum measurement value and a minimum measurement value based on the first measurement value, and transmit the maximum measurement value and the minimum measurement value to the memory 40 for recording, and the measurement values between the maximum measurement value and the minimum measurement value are not required to be recorded.

In the above embodiment, since the current measurement value, the maximum measurement value, and the minimum measurement value are generated by the chip 30, the display 50 may be configured to capture the current measurement value, the maximum measurement value, and the minimum measurement value directly from the chip 30 for display. Of course, the display 50 may be configured to capture only the current measurement value from the chip 30 for display, and capture the maximum measurement value and the minimum measurement value from the memory 40 for display.

It should be understood that the driving mechanism may be designed in various forms as long as it can convert the distance moved by the probe 10 into an electrical signal and transmit the electrical signal to the chip 30. For example, the driving mechanism may include a monitoring unit and a sensor, the sensor is disposed on the probe 10 and can move along with the probe 10, and the monitoring sensor can monitor the moving distance of the sensor in real time, so that the moving distance of the sensor is converted into a measurement value and transmitted to the chip 30.

When the probe 10 reciprocates along its own axis, since the position of the first contact pin 21 is always unchanged and the contact piece 22 changes in position along with the movement of the probe 10, the resistance in the first circuit also changes at this time, resulting in a change in voltage, so that the chip 30 can calculate how much distance the probe 10 has moved according to the related voltage and resistance, that is, convert the electrical signal into a measurement value.
In order to make the probe 10 move back and forth along its axis easily and conveniently, in one embodiment of the present invention, the transmission mechanism includes a first fixed seat 23 and a first spring 24; the first fixing seat 23 is fixedly arranged and provided with a through hole, and one end of the probe 10 penetrates through the through hole; the two ends of the first spring 24 are respectively connected with the first fixed seat 23 and the contact piece 22.

The zeroing operation may be automatic or manual, for example, the chip 30 may be configured to set the current position of the probe 10 as an initial position upon receiving a prompt signal, so as to implement an automatic zeroing operation, or of course, the chip 30 may be controlled to implement a zeroing operation by manually pressing a key.
It will be appreciated that the alert mechanism may take a variety of forms so long as it is capable of emitting an alert signal when in contact with the probe 10. For example, the notification mechanism may include the second contact pin 61, the notification lamp 62, and the second circuit; the second contact pin 61, the indicator light 62 and the probe 10 are respectively connected in series with the second circuit; the second contact pin 61 is disposed so as to be movable in the axial direction of the probe 10 so as not to affect the movement operation of the probe 10; the second circuit is configured to be able to form a closed loop when the probe pin 10 contacts the second contact pin 61 and to be able to be opened when the probe pin 10 is detached from the second contact pin 61.
Specifically, the prompting mechanism further comprises a second fixed seat 63 and a second spring 64; the second fixing seat 63 is fixedly arranged, and two ends of the second spring 64 are respectively connected with the second fixing seat 63 and the second contact pin 61. That is, when the probe 10 moves away from the surface to be measured, the probe 10 can push the second contact pin 61 to move together, at this time, the second contact pin 61 presses the second spring 64, and when the probe 10 moves toward the surface to be measured, the second contact pin 61 can return to the initial position by the elastic force of the second spring 64. The prompting mechanism of the embodiment has the advantages of simple structure, easiness in maintenance and low manufacturing cost.
