The inner wall of the guide rail 3 is fixedly connected with a limit block 1 through a bolt. By arranging two groups of limit blocks 1 on both sides of the inner wall of the guide rail 3, when the guide rail 3 moves along the outer wall of the slider 6, the situation of falling off will not occur. There are two groups of limit blocks 1, and the two groups of limit blocks 1 are symmetrically distributed at both ends of the inner wall of the guide rail 3, achieving the effect of limiting the guide rail 3. The outer wall of one group of limit blocks 1 is threadedly connected with a fastening bolt, and the outer wall of the fastening bolt is slidably connected with an adjustment block 4, so that the adjustment block 4 can move horizontally along the outer wall of the limit block 1, achieving the effect of secondarily adjusting the position of the infrared emitter 7, and cooperating with the inward rotation of the fastening bolt to fit and fix. The outer wall of the adjustment block 4 is fixedly connected with an infrared emitter 7. The infrared emitter 7 can emit a pair of tubes to form a scanning grid in the horizontal and vertical directions, forming a scanning plane network. When an object that can block infrared light blocks a certain pair of horizontal and vertical infrared scanning lines in the grid, the X and Y coordinates can be determined through the positions of the blocked horizontal and vertical infrared rays, realizing the positioning of the coordinates. And the infrared emitter 7 is a prior art, and the specific model is: E18-D80NK.
[0034] Refer to Figure 2 - Figure 3 , a jerky mechanism 9 is arranged on the guide rail 3. The jerky mechanism 9 includes a guide rod 901, the bottom of the guide rod 901 is fixedly connected with the top of the guide rail 3, so that the guide rail 3 provides a supporting and fixing effect for the guide rod 901. The outer wall of the guide rod 901 is slidably connected with a plate body 902, so that the stability of the plate body 902 during vertical movement is maintained by the cooperation of the guide rod 901 and the T-shaped rod 903. The inner wall of the plate body 902 is slidably connected with a two-way wedge block 904, so that the two-way wedge block 904 moves vertically along the inner wall of the plate body 902. The outer wall of the two-way wedge block 904 is fixedly connected with one end of a spring A905, and the other end of the spring A905 is fixedly connected with the inner wall of the plate body 902, and the two-way wedge block 904 is driven to move downward by the force of the spring A905, so that the two-way wedge block 904 maintains the plugging and fixing effect with the card slot.
[0035] Refer to Figure 1 - Figure 3, a concave frame 906 is fixedly connected to the top of the slider 6, so that the slider 6 provides a supporting and fixing effect for the concave frame 906. A clamping groove is formed in the top of the concave frame 906, and the inner wall of the clamping groove is inserted into the inner wall of the two-way wedge block 904. The concave frame 906 is fixed to the guide rail 3 by means of insertion. A T-shaped rod 903 is fixedly connected to the top of the guide rail 3, so that the guide rail 3 provides a supporting and fixing effect for the T-shaped rod 903. The outer wall of the T-shaped rod 903 is slidably connected to the inner wall of the plate body 902 to maintain the stability of the plate body 902 during movement. A handle is fixedly connected to the outer wall of the plate body 902. The plate body 902 is vertically moved by moving the handle. A pull rod 908 is slidably connected to the inner wall of the handle, so that the pull rod 908 moves horizontally along the inner wall of the handle. A limiting rod 907 is fixedly connected to the outer wall of the pull rod 908, so that the limiting rod 907 moves simultaneously when the pull rod 908 moves horizontally. Fixing holes 910 are formed in the outer wall of the guide rod 901, and two groups of fixing holes 910 are provided. The two groups of fixing holes 910 respectively correspond to two situations where the straight surface of the two-way wedge block 904 is inserted into the clamping groove and the inclined surface of the two-way wedge block 904 is inserted into the clamping groove. The outer end of the limiting rod 907 is inserted into the inner wall of the fixing hole 910 to achieve the effect of fixing the vertical position of the plate body 902. One end of the pull rod 908 is fixedly connected to one end of the spring B909, and the other end of the spring B909 is fixedly connected to the inner wall of the plate body 902. The limiting rod 907 is driven to move inwards by the force of the spring B909, so that the limiting rod 907 maintains the insertion and fixing effect with the fixing hole 910. The outer wall of the limiting rod 907 is slidably connected to the inner wall of the plate body 902 to maintain the stability of the limiting rod 907 during horizontal movement.
[0036] Working principle: When positioning is required, hold the handle and pull the pull rod 908 arranged on the inner wall of the handle, so that the pull rod 908 drives the limiting rod 907 to move outwards, separating the limiting rod 907 from the inner wall of the fixing hole 910, thereby releasing the fixing effect on the plate body 902, and vertically moving the handle, so that the handle drives the plate body 902 to move vertically, thereby achieving the effect of changing the height of the plate body 902. At the same time, the two-way wedge block 904 arranged on the plate body 902 also moves upwards, separating the straight surface at the top of the two-way wedge block 904 from the clamping groove at the top of the concave frame 906, and bringing the inclined surface of the two-way wedge block 904 into contact with the clamping groove, achieving the purpose of releasing the fixing effect on the guide rail 3 and the concave frame 906.
[0037] Then, push the guide rail 3 to move laterally, so that the guide rail 3 maintains lateral movement along the outer wall of the slider 6, thereby driving the change of the lateral position of the infrared emitter 7 arranged on the inner wall of the guide rail 3, aligning and positioning the position of the infrared emitter 7 with the center of the specimen. At the same time, during the lateral movement of the guide rail 3, the inclined surface at the bottom of the two-way wedge 904 will be squeezed and collided with the card slot, thereby achieving a jerky effect. When the staff moves the guide rail 3 to the designated position, they will receive a prompt that the two-way wedge 904 is inserted into the card slot, thus ensuring the accuracy during the process of adjusting the position of the guide rail 3. Then, by moving the plate body 902 downward, the plate body 902 drives the top straight surface of the two-way wedge 904 to fully fit and insert into the card slot, achieving the effect of fixing the position of the guide rail 3.

The inner wall of the guide rail 3 is fixedly connected with a limiting block 1 by bolts. There are two groups of limiting blocks 1, and the two groups of limiting blocks 1 are symmetrically distributed at both ends of the guide rail 3. The outer wall of one group of limiting blocks 1 is threadedly connected with a fastening bolt. The outer wall of the fastening bolt is slidably connected with an adjusting block 4. The outer wall of the adjusting block 4 is fixedly connected with an infrared emitter 7. A limiting hole 8 is formed on the outer wall of the guide rail 3. A through hole is formed on the outer wall of the aluminum connecting plate 2. A magnetic attraction positioning block 5 penetrates through the inner wall of the limiting hole 8. The outer end of the magnetic attraction positioning block 5 is inserted into and magnetically connected with the inner wall of the through hole. By opening the limiting hole 8 on the outer wall of the guide rail 3 and cooperating with the magnetic attraction positioning block 5 to penetrate through the limiting hole 8 and be inserted and fixed with the aluminum connecting plate 2, the effect of connecting and fixing the guide rail 3 and the slider 6 is achieved.
[0040] Working principle: By pulling out the magnetic attraction positioning block 5 outward, the fixing effect between the guide rail 3 and the aluminum connecting plate 2 is released, and the guide rail 3 is moved laterally, so that the guide rail 3 moves laterally along the outer wall of the slider 6 and drives the infrared emitter 7 to move laterally at the same time. After moving to the designated position, the magnetic attraction positioning block 5 penetrates through the limiting hole 8 and is inserted into the inner wall of the through hole, achieving the purpose of fixing the guide rail 3 and the aluminum connecting plate 2, fixing the lateral position of the infrared emitter 7, and at the same time, the lateral position of the infrared emitter 7 can be secondarily adjusted by rotating the fastening bolt, improving the accuracy of the device during positioning.
