The reading pen body 1 recognizes the OID code through the infrared light sensor head 6, and after the microcontroller unit analyzes it, it finds the corresponding index number. The program of the reading pen body 1 will perform the corresponding operation according to the index number. A threaded ring 8 is installed at the bottom of the reading pen body 1. An insertion groove 16 is opened in the middle of the pen head body 2, and a threaded groove 15 is opened on the upper side of the inner wall of the insertion groove 16. The left and right sides of the top of the pen head body 2 are provided. There are card columns 11 inserted on both sides, and card slots 5 are provided on the left and right sides of the bottom of the reading pen body 1. An anti-collision ring 10 is installed at the bottom end of the pen body 2, and an anti-slip groove 3 is provided on the outside of the pen body 2; the infrared light sensor head 6 is inserted into the inner wall of the insertion groove 16, and the outer side of the threaded ring 8 is threadedly connected to the inner wall of the threaded groove 15, so that the pen body 2 can be easily disassembled for maintenance of its internal components. The top of the card column 11 passes through the pen body 2 and is inserted into the inner wall of the card slot 5, so that the assembly between the card column 11 and the card slot 5 is utilized to increase the stability of the assembly between the pen body 2 and the reading pen body 1, thereby improving its use effect.

[0023] First, hold the anti-slip groove 3 and rotate the pen body 2, so that the top of the clamping column 11 slides along the inner wall of the auxiliary groove 9 and gradually separates from the reading pen body 1. As the pen body 2 gradually separates from the outer side of the threaded ring 8, the clamping column 11 will separate from the bottom of the reading pen body 1, so that the pen body 2 can be removed downward and the infrared light sensor head 6 can be separated from the insertion groove 16. Then the infrared light sensor head 6 can be maintained. After completion, the pen body 2 is placed on the infrared light sensor head. 6, and gradually moves upward by utilizing the cooperation between the threaded groove 15 and the threaded ring 8. At this time, the infrared light sensor head 6 is gradually installed downward to the bottom of the insertion groove 16, and the card column 11 will gradually approach the auxiliary groove 9, and the card column 11 will be pushed and retracted to the inner wall of the movable groove 13. When the pen body 2 and the threaded ring 8 are fully assembled, the top of the card column 11 is always kept connected with the card slot 5, thereby increasing the stability of the reading pen body 1 and the pen body 2 after assembly.

[0024] Embodiment 2: On the basis of embodiment 1, in order to push the card column 11 to always be fitted between the card slot 5, movable grooves 13 are provided on the left and right sides of the upper part of the pen body 2, and a limit plate 12 is installed on the inner wall of the movable groove 13, and an elastic member 14 is installed on the bottom of the limit plate 12. Auxiliary grooves 9 are provided on the left and right sides of the bottom of the reading pen body 1; the bottom end of the elastic member 14 is installed at the bottom of the inner wall of the movable groove 13, so that the elastic force of the elastic member 14 is used to push the top of the card column 11 to always remain plugged in between the card slot 5, thereby improving the assembly stability of the pen body 2, and the limit plate 12 is installed between the top and the card column 11, so that the setting of the limit plate 12 is used to prevent the card column 11 from separating from the pen body 2, and the auxiliary groove 9 is connected with the card slot 5, so that the auxiliary groove 9 is used to guide the card column 11 to facilitate its insertion into the inner wall of the card slot 5 and facilitate the subsequent unscrewing of the pen body 2.

[0025] First, rotate the pen body 2, thereby driving the top of the clamping column 11 to slide along the inner wall of the auxiliary groove 9 and gradually separate from the reading pen body 1. As the pen body 2 gradually separates from the outside of the threaded ring 8, the clamping column 11 will separate from the bottom of the reading pen body 1, so that the pen body 2 can be removed downward, and the infrared light sensor head 6 can be separated from the insertion groove 16. At the same time, the rubber pad 7 can be separated from the fitting groove 4. Then the infrared light sensor head 6 can be maintained. After completion, the pen body 2 is placed on the outside of the infrared light sensor head 6 and the threaded ring 8 is used to remove the infrared light sensor head 6. The groove 15 cooperates with the threaded ring 8 and gradually moves upward. At this time, the infrared light sensor head 6 is gradually installed downward to the bottom of the insertion groove 16, and the card column 11 will gradually approach the auxiliary groove 9, and the card column 11 is pushed to the inner wall of the movable groove 13. When the pen body 2 and the threaded ring 8 are fully assembled, at this time, the elastic force of the elastic member 14 is used to push the limit plate 12 upward, and drive the top of the card column 11 to always remain plugged in between the card slot 5, thereby increasing the stability between the reading pen body 1 and the pen body 2 after assembly.

[0026] Example 3: On the basis of Example 2, in order to increase the sealing of the pen tip body 2 after assembly and improve the stability of the infrared light sensor head 6 inside it, a fitting groove 4 is opened at the bottom of the reading pen body 1, a rubber pad 7 is installed on the top of the pen tip body 2, and a rubber ring 17 is installed on the lower part of the inner wall of the insertion groove 16; the rubber pad 7 is inserted into the inner wall of the fitting groove 4, and the rubber pad 7 is in an extruded deformation state, thereby increasing the sealing between the pen tip body 2 and the reading pen body 1 when assembled between the two, preventing water from entering, and thereby improving its use effect and service life; the rubber ring 17 is sleeved on the outside of the infrared light sensor head 6, and is squeezed and pushed into a deformed state, thereby increasing the friction between the infrared light sensor head 6 and the pen tip body 2, thereby improving its stability after insertion.

[0027] The pen tip body 2 is placed on the outside of the infrared light sensing head 6, and is gradually moved upward by utilizing the cooperation between the threaded groove 15 and the threaded ring 8. At this time, the infrared light sensing head 6 is gradually installed downward to the bottom of the insertion groove 16, and pushes the rubber ring 17 to make it deformed, thereby utilizing the rubber ring 17 to increase the stability between the infrared light sensing head 6 and the pen tip body 2. When the pen tip body 2 and the threaded ring 8 are fully assembled, the rubber pad 7 will be inserted into the inner wall of the fitting groove 4, thereby increasing the sealing between the reading pen body 1 and the pen tip body 2, preventing water from entering, and thereby increasing the service life of the internal components of the reading pen body 1.

[0028] During actual use, first hold the anti-slip groove 3 and rotate the pen body 2, thereby driving the top of the clamping column 11 to slide along the inner wall of the auxiliary groove 9 and gradually separate from the reading pen body 1. As the pen body 2 gradually separates from the outside of the threaded ring 8, the clamping column 11 will separate from the bottom of the reading pen body 1, so that the pen body 2 can be removed downward, and the infrared light sensor head 6 can be separated from the insertion groove 16. At the same time, the rubber pad 7 can be separated from the fitting groove 4. Then the infrared light sensor head 6 can be maintained. After completion, the pen body 2 is placed on the outside of the infrared light sensor head 6, and the threaded groove 15 and the threaded ring 8 are used to gradually move upward. At this time, the infrared light sensor head 6 is gradually installed downward to the bottom of the insertion groove 16 and pushes the rubber pad 7 against the fitting groove 4. The rubber ring 17 is deformed to increase the stability between the infrared light sensing head 6 and the pen tip body 2. The card column 11 will gradually approach the auxiliary groove 9, and the card column 11 will be pushed to the inner wall of the movable groove 13. When the pen tip body 2 and the threaded ring 8 are fully assembled, the elastic force of the elastic member 14 is used to push the limit plate 12 upward, and drive the top of the card column 11 to always remain plugged in between the card slot 5, thereby increasing the stability between the reading pen body 1 and the pen tip body 2 after assembly. At the same time, the rubber pad 7 will be inserted into the inner wall of the fitting groove 4, thereby increasing the sealing between the reading pen body 1 and the pen tip body 2, preventing water from entering, and thereby improving the service life of the internal components of the reading pen body 1.
