[0036] In one embodiment, the handheld measuring device further comprises an external antenna 5 installed on the handheld measuring device body 10.
[0037] The external antenna 5 is added to enhance wireless signal transmission and play a signal enhancement role.
[0038] In one embodiment, handheld point positions are symmetrically arranged on two sides of the handheld measuring device.
[0039] The two sides of the handheld measuring device are used for handheld, and the handheld point positions can be symmetrically arranged on the two symmetric sides.
[0040] In one embodiment, the distance between the handheld point position and the rear end of the handheld measuring device body 10 is less than or equal to the preset point distance, and the preset point distance is the average value of the distance from the tip of the thumb to the center point of the empty fist when the human hand holds the empty fist.
[0041] In order to facilitate single-handed operation, the distance between the handheld point and the rear end of the handheld measuring device body 10 is less than or equal to the point preset distance, and the point preset distance is the average value of the distance from the tip of the thumb to the center point of the empty fist when an adult holds the empty fist.
[0042] In one of the embodiments, the distance between the center point of the touch-sensitive key module 3 and the rear end of the handheld measuring device body 10 is less than or equal to the touch preset distance, and the touch preset distance is the average value of the distance from the tip of the index finger to the center point of the empty fist when an adult holds the empty fist.
[0043] In order to facilitate single-handed operation, the distance between the center point of the touch-sensitive key module 3 and the rear end of the handheld measuring device body 10 is less than or equal to the touch preset distance, and the touch preset distance is the average value of the distance from the tip of the index finger to the center point of the empty fist when an adult holds the empty fist.
[0044] In one of the embodiments, the touch-sensitive key module 3 is embedded and installed on the surface of the handheld measuring device body 10 and is in a horizontal plane with the surface of the handheld measuring device body 10.

At this time, if the operator cannot press the touch-sensitive key module 3, a key that replaces the touch-sensitive key module 3 can be arranged on the telescopic rod, and the function of taking pictures can be realized through this key. At the same time, the lengthening function of the telescopic rod also makes it convenient for operators to pass the handheld measuring device.
[0050] In one of the embodiments, the display module 4 is a liquid crystal display module.
[0051] The liquid crystal display module is integrated at the front end or top of the handheld measuring device body 10, and displays the captured image and measurement results in real time. The liquid crystal display module is designed with a high refresh rate, and is particularly suitable for use in high-altitude or narrow spaces that are difficult to reach. During the measurement process, the operator can view the real-time image through the liquid crystal display module while observing the entire measured area, without needing to significantly adjust the line of sight direction, thereby ensuring accurate alignment of the crack position during measurement.

First, the operator determines the crack position to be measured by visual observation, and then positions the front end of the handheld measuring device 1 to the measured crack position. Since the display module 4 is located at the front end, the operator can directly view the real-time image and measurement results through the display module 4, ensuring accurate alignment of the crack, without needing to separately view the picture display of the external handheld display device 2. This design is particularly suitable for high-altitude work and work in narrow spaces, avoiding the inconvenience and danger caused by frequent head lowering to view the external screen.
[0055] When the operator confirms the crack position through the display module 4 and views the crack width data in real time, if the measurement data meets the expectation, the operator can trigger the photographing by lightly pressing the long-pressing touch-sensitive key module 3. The design of the touch-sensitive key module 3 effectively avoids the change of the probe position that may be caused by the traditional physical key when triggering the photographing, thereby avoiding image blur and measurement error.
[0056] The setting of the handheld display device 2 enables another operator to view the real-time data away from the handheld measuring device 1.
