At this time, the bristles 18 will contact the surface of the detection needle 19, and the spring telescopic rod 11 will be in a compressed state. When the detection is completed, the spring telescopic rod 11 rebounds to reset the fixing frame 12, the first fixing rod 13, the second fixing rod 14, the fixing ring 15, the third fixing rod 16, the push rod 17, and the bristles 18. In this step, by arranging the spring telescopic rod 11, the fixing frame 12, the first fixing rod 13, the second fixing rod 14, the fixing ring 15, the third fixing rod 16, the push rod 17, and the bristles 18, the bristles 18 can be allowed to reciprocate and brush the surface of the detection needle 19 when detecting wood, thereby reducing dust and wood chips attached to the surface of the detection needle 19, and making the detection more accurate.

[0026] like Figure 4As shown, the side wall of the fixing frame 12 is fixedly connected to the first fixing frame 2; the side wall of the first fixing frame 2 is provided with a pair of slide grooves 22; the pair of slide grooves 22 are symmetrically arranged; the slide groove 22 is slidably connected to a slider 24; the side wall of the slider 24 is fixedly connected to the second fixing frame 21; a return spring 23 is provided in the middle of the slide groove 22; the two ends of the return spring 23 are respectively fixedly connected to the slider 24 and the first fixing frame 2; when working, when the detector body 1 is pushed close to the wood, the second fixing frame 21 will contact with the wood and slide on the surface of the first fixing frame 2 toward the top of the detector body 1, and this When the return spring 23 is in a compressed state, when the push rod 17 contacts the wood, the fixing frame 12 will move toward the top of the detector body 1. When the detection needle 19 contacts the wood, the return spring 23 will rebound to make the top of the second fixing frame 21 contact the wood. This step can make the detection needle 19 covered inside the second fixing frame 21 when detecting wood by setting the first fixing frame 2, the second fixing frame 21, the slide groove 22, the return spring 23, and the slider 24. When the air around the wood is relatively humid, the detection needle 19 is detected inside the second fixing frame 21, which can reduce the influence of external humidity on the detection.

[0027] like Figure 4 As shown, a plurality of rubber strips 3 are fixedly connected to the top of the second fixed frame 21; the plurality of rubber strips 3 are evenly distributed on the top of the second fixed frame 21; the rubber strips 3 are made of flexible material; during operation, when the detector body 1 is pushed close to the wood, the rubber strips 3 will contact the wood. In this step, the gap between the second fixed frame 21 and the wood is reduced by setting the rubber strips 3. When the surface of the wood is irregular and has dents, the rubber strips 3 can be inserted into the dents to reduce the gap between the surface of the wood and the second fixed frame 21, so that the detection needle 19 is more tightly covered by the second fixed frame 21.

[0028] like Figure 1 to Figure 2 As shown, the top of the detector body 1 is hinged with a top cover 4; the side wall of the top cover 4 is fixedly connected to a first magnet 41; the side wall of the detector body 1 is fixedly connected to a second magnet 42; the first magnet 41 and the second magnet 42 are arranged to attract each other; during operation, when it is necessary to detect the wood, the top cover 4 is rotated first, at this time the first magnet 41 and the second magnet 42 are separated, and when the use is over, the top cover 4 is rotated again to make the first magnet 41 and the second magnet 42 close to each other and attracted together. This step allows the detector body 1 to be opened and closed more easily than the plug-in top cover 4 during detection by arranging the top cover 4, the first magnet 41, and the second magnet 42, and can also reduce the wear on the detector body 1 caused by opening and closing the plug-in top cover 4.

[0029] like Figure 5As shown, the inner wall of the top cover 4 is fixedly connected to a third fixed frame 5; the bottom of the third fixed frame 5 is fixedly connected to a mesh plate 51; a plurality of circular holes 52 are opened in the middle of the mesh plate 51; during operation, a desiccant can be added to the inside of the third fixed frame 5, and the desiccant will absorb the moisture inside the top cover 4 from the circular holes 52. In this step, the desiccant can be stored in the third fixed frame 5 by setting the third fixed frame 5, the mesh plate 51, and the circular holes 52. When the detector body 1 is finished using, the top cover 4 is closed. At this time, the desiccant inside the third fixed frame 5 can absorb the moisture inside the top cover 4, so that the inside of the top cover 4 remains dry, thereby reducing the corrosion of water to various components.

[0030] like Figure 2 As shown, a slot 61 is provided on the side wall of the detector body 1; a support rod 6 is hinged on the side of the detector body 1; the support rod 6 and the slot 61 are rotatably matched; during operation, when the detector body 1 needs to be temporarily placed, the support rod 6 can be rotated so that there is a certain angle between the support rod 6 and the side wall of the detector body 1, and the support rod 6 is retracted into the slot 61 after the placement is completed. In this step, by setting the support rod 6 and the slot 61, when the detector body 1 needs to be temporarily placed after the detection of a piece of wood is completed, the support rod 6 can keep the detector body 1 in a standing state, thereby reducing the situation where soil and wood chips enter the top of the detector body 1 when the detector body 1 is placed flat, causing pollution to the various components on the top of the detector body 1.

[0031] like Figure 2 As shown, a protective cover 7 is fixedly connected to the bottom of the detector body 1; during operation, when the detector body 1 is placed, the protective cover 7 will contact the ground. In this step, by setting the protective cover 7, when the detector body 1 is placed in coordination with the support rod 6, the friction between the detector body 1 and the ground can be reduced, thereby reducing the wear of the detector body 1.

[0032] Working principle: During operation, when wood is detected, when the detector body 1 is pushed close to the wood, the push rod 17 will be pushed back by the wood to make the fixed frame 12 move toward the top of the detector body 1, which can drive the first fixed rod 13, the second fixed rod 14, the fixing ring 15, the third fixed rod 16, the push rod 17, and the bristles 18 to move toward the top of the detector body 1 at the same time. At this time, the bristles 18 will contact the surface of the detection needle 19, and the spring telescopic rod 11 will be in a compressed state. When the detection is completed, the spring telescopic rod 11 rebounds to reset the fixed frame 12, the first fixed rod 13, the second fixed rod 14, the fixing ring 15, the third fixed rod 16, the push rod 17, and the bristles 18. When the detector body 1 is pushed close to the wood, the second fixed frame 21 will contact the wood and slide toward the top of the detector body 1 on the surface of the first fixed frame 2. At this time, the reset spring 23 is in a compressed state. When 17 contacts with the wood, the fixing frame 12 will move toward the top of the detector body 1. When the detection needle 19 contacts with the wood, the reset spring 23 will rebound to make the top of the second fixing frame 21 contact with the wood. When the detector body 1 is pushed close to the wood, the rubber strip 3 will contact with the wood. When it is necessary to detect the wood, the top cover 4 is rotated first. At this time, the first magnet 41 and the second magnet 42 are separated. After use, the top cover 4 is rotated again to make the first magnet 41 and the second magnet 42 close and sucked together. Desiccant can be added to the inside of the third fixing frame 5. The desiccant will absorb the moisture inside the top cover 4 from the circular hole 52. When the detector body 1 needs to be temporarily placed, the support rod 6 can be rotated so that the support rod 6 has a certain angle with the side wall of the detector body 1. After placement, the support rod 6 is retracted into the slot 61. When the detector body 1 is placed, the protective cover 7 will contact the ground.
