[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1-3This utility model provides an embodiment of a scanner that is easy to adjust and fix, including a base 1. An anti-slip pad 18 is fixedly connected to the bottom of the base 1. By setting the anti-slip pad 18, the friction between the base 1 and the placement surface can be increased, improving the stability of the base 1. A scanning bracket 2 is fixedly connected to the top of the base 1. A grooved sleeve plate 3 is fixedly connected to the front right side of the scanning bracket 2. A movable sleeve plate 4 is slidably connected inside the grooved sleeve plate 3. A scanning head 5 is fixedly installed on the right side of the bottom of the movable sleeve plate 4. Slots 6 are provided on both the front and rear sides of the top of the grooved sleeve plate 3. A trapezoidal sleeve plate 7 is fixedly connected to the left side of the top of the movable sleeve plate 4 via a connecting block. A concave limiting plate 20 is fixedly connected to the top of the trapezoidal sleeve plate 7. By setting the concave limiting plate 20, the pulling distance of the pull sleeve plate 9 can be limited, and the comfort of the user when pulling the pull sleeve plate 9 can be increased. A sealing ring 22 is fixedly connected to the top of the trapezoidal sleeve plate 7. The inner side of 2 contacts the surface of the I-shaped pull plate 8. By setting the sealing ring 22, dust can be reduced from entering the interior of the trapezoidal sliding sleeve 12, and dust can be prevented from accumulating inside the trapezoidal sliding sleeve 12. The trapezoidal sleeve 7 is provided with an I-shaped pull plate 8 inside. The top of the I-shaped pull plate 8 extends through to the top of the trapezoidal sleeve 7 and is fixedly connected to the pull plate 9. The surface of the pull plate 9 is covered with a rubber sleeve 21. By setting the rubber sleeve 21, the hand slippage can be prevented, improving the convenience and efficiency of operation. The front and rear sides of the interior of the I-shaped pull plate 8 are fixedly connected to the slide rod 10. The front and rear sides of the inner wall of the trapezoidal sleeve 7 are movably connected to the rotating rod 11. The surface of the rotating rod 11 is slidably connected to the sliding sleeve 12. The surface of the slide rod 10 is slidably connected to the interior of the sliding sleeve 12. The left and right sides of the sliding sleeve 12 away from the I-shaped pull plate 8 are fixedly connected to the arc-shaped clamping plate 13. The arc-shaped clamping plate 13 extends through to the bottom of the trapezoidal sleeve 7 and extends into the interior of the clamping groove 6.

[0033] Reference Figure 1-3 The base 1 has a load-bearing component on its surface, which includes a load-bearing plate 14. The load-bearing plate 14 is located on the front and rear sides of the base 1. A rotating rod 15 is fixedly connected to the left side of the load-bearing plate 14. Support blocks 16 are slidably sleeved on the top and bottom of the rotating rod 15. The side of the support block 16 closest to the base 1 is fixedly connected to the surface of the base 1. By setting up the load-bearing component, the stability of the base 1 can be improved, and the base 1 can be prevented from shaking when the scanning head 5 moves to the right, which would prevent the scanning head 5 from scanning the drawing clearly. Magnet pieces 19 are fixedly connected to the front and rear sides of the top of the base 1. The bottom of the magnet pieces 19 is attracted to the top of the load-bearing plate 14. By setting up the magnet pieces 19, the load-bearing plate 14 can be attracted and fixed, preventing the load-bearing plate 14 from shifting when it is not in use.

[0034] Reference Figure 1-3The surface of the sliding sleeve 12 is provided with a reset component, which includes a tension spring 17. The tension spring 17 is fixedly connected to the bottom of the sliding sleeve 12, and the bottom of the tension spring 17 is fixedly connected to the bottom of the inner wall of the trapezoidal sleeve plate 7. By setting the tension spring 17, it is easy for the staff to quickly reset the sliding sleeve 12, thereby driving the arc-shaped card plate 13 to be inserted into the inside of the card slot 6.

[0035] Working principle: When adjusting the scanning range of the scanning head 5, the operator first pulls the pull sleeve plate 9 upwards. The pull sleeve plate 9 drives the I-shaped pull plate 8 upwards, and the I-shaped pull plate 8 drives the slide rod 10 to slide upwards inside the slide sleeve 12. At this time, the two slide sleeves 12 rotate around the rotating rod 11 and move closer to each other. The tension spring 17 at the bottom of the slide sleeve 12 will be stretched. When the top of the pull sleeve plate 9 is pulled and contacts the bottom of the concave limiting plate 20, the slide sleeve 12 can drive the arc-shaped clamping plate 13 to rotate around the rotating rod 11 and disengage from the inside of the clamping slot 6. Then, the operator moves the concave limiting plate 20 to the right to adjust the scanning range of the scanning head 5. When the appropriate position is reached, the operator releases the pull sleeve plate 9, and the tension spring 17 at the bottom of the slide sleeve 12 will pull the slide sleeve 12, the I-shaped pull plate 8 and the pull sleeve plate 9 downwards, and re-clamp the arc-shaped clamping plate 13 into the inside of the clamping slot 6 for fixation. Then, the drawing is scanned.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
