[0026] An inner cavity 7 is defined inside the protective bottom bar 2 , and a first spring 8 is installed inside the inner cavity 7 .

[0027] The needle body 1 forms a telescopic structure with the protective bottom rod 2 through the first spring 8, and the needle body 1 forms a sliding structure with the protective bottom rod 2 through the limiting bolt 4, so that the needle body 1 can be installed inside the protective bottom rod 2, and then the position of the needle body 1 can be adjusted by the first spring 8 installed inside the protective bottom rod 2, so that the first spring 8 can be used to reduce the shock of the needle body 1 during use, so as to avoid damage caused by sudden touch during the detection process.

[0028] The protective outer ring 5 forms a detachable structure with the protective bottom rod 2 through the fixing bolts 6, and the sizes of the protective outer ring 5 and the protective bottom rod 2 match each other, so that the protective outer ring 5 can be installed through the fixing bolts 6. During installation, the position of the limiting groove 3 can be limited, which is convenient for adjusting the longest length of the needle body 1 inside the device and facilitating the use of the device.

[0029] Example 2
