Through holes 8 are provided at the upper and lower ends of the right side of sleeve 2 7. The through holes 8 are provided to provide a driving source for driving sleeve 2 7 and to limit the telescopic distance of sleeve 2 7. The top of the inside of sleeve 2 7 is fixedly connected with a motor 9. Motor 9 is fixed at the right end of the inner wall of sleeve 2 7. The driving end of motor 9 is fixedly connected with a main gear 10. When motor 9 is started, it drives the main gear 10 to rotate. The inner wall of the through hole 8 at the bottom is rotatably connected with a slave gear 11. After the main gear 10 rotates, sleeve 2 7 will slide, thereby indirectly driving the slave gear 11 to rotate.

[0026] The inner wall of the sleeve 7 is slidably connected with a detection head 12, and the right side of the detection head 12 is fixedly connected with a limit assembly. The detection head 12 is the part for detecting data, and the length of the detection head 12 can be further increased by extending and retracting the limit assembly to reduce the distance between the instrument body 1 and the material to be measured. Compared with the above documents, the length of the detection head 12 is increased on the original basis, allowing the user to adjust the distance between the detection head 12 and the target object as needed to obtain more accurate detection results.

[0027] refer to Figure 2 , Figure 3 A handle 17 is fixedly connected to the right side of the top of the instrument body 1, and the handle 17 is fixed to the top of the instrument body 1, which is convenient for users to pick up the equipment. A display screen 18 is set in the middle of the top of the instrument body 1, and the display screen 18 displays the detection data, which is convenient for users to observe in real time. A protective shell 19 is fixedly connected to the left side of the top of the instrument body 1, and the protective shell 19 is fixed to the outside of the display screen 18 to protect the display screen 18 and prevent the display screen 18 from being hit. The rear end of the main gear 10 is rotatably connected to the rear side of the inner wall of the through hole 8, thereby realizing the stable rotation of the main gear 10. The external teeth of the main gear 10 are meshed with the external teeth of the top rack plate 6, and the external teeth of the slave gear 11 are meshed with the external teeth of the bottom rack plate 6. The main gear 10 is meshed with the rack plate 6 and synchronously drives the sleeve 2 7 to slide to the left with the slave gear 11.

[0028] refer to Figure 3-Figure 5 The limit assembly includes a tooth plate 13 and a limit block 14. The left end of the tooth plate 13 is fixedly connected to the right end of the detection head 12, and the right end of the tooth plate 13 is fixedly connected to the left end of the limit block 14. The detection head 12 is connected to the tooth plate 13. The top teeth of the tooth plate 13 are meshed with the external teeth of the main gear 10, and the bottom teeth of the tooth plate 13 are meshed with the external teeth of the slave gear 11. The external teeth of the main gear 10 and the slave gear 11 will mesh and drive the tooth plate 13 to extend and retract to the left between the main gear 10 and the slave gear 11.

[0029] The upper and lower sides of the limit block 14 are slidably connected to the inner wall of the sleeve 4, and the limit block 14 limits the sliding distance of the detection head 12. The right rear end of the detection head 12 is fixedly connected with a protective cover 15, and the right side of the detection head 12 is fixedly connected with a transmission line 16. The protective cover 15 is sleeved on the outside of the transmission line 16. The detection head 12 fixes the protective cover 15 so that the protective cover 15 protects the transmission line 16, so that the transmission line 16 does not interfere with the movement of other components. The right side of the transmission line 16 is connected to the instrument body 1 by an electric wire. The transmission line 16 connects the detection head 12 and the instrument body 1, so that the data is transmitted to the instrument body 1 for analysis and then displayed on the display screen 18.

[0030] Working principle: When the user needs to increase the contact area and distance between the detection head 12 and the detected object, the control system inside the instrument body 1 can control the motor 9 fixed on the inner wall of the sleeve 2 7 to start. The motor 9 starts to drive the main gear 10 to rotate, and the rotation of the main gear 10 drives the slave gear 11 to rotate synchronously and mesh on the teeth of the rack plate 6, so that the sleeve 2 7 can be extended to the left. When the sleeve 2 7 is extended to the left, the outer teeth of the main gear 10 and the slave gear 11 will mesh and drive the tooth plate 13 to extend to the left between the main gear 10 and the slave gear 11. The tooth plate 13 will synchronously drive the fixedly connected detection head 12 to extend to the left, thereby realizing the extension and expansion of the entire sleeve 1 4, sleeve 2 7 and detection head 12, so that the contact area of ​​the detection head 12 with the detected object is increased, and the distance to the detected object is reduced to obtain more accurate detection results.
