When in use, the position of the piston 7 can be adjusted to adjust the air pressure in the middle large circular groove at the bottom of the base 2, so that the device can be adsorbed and fixed through the base 2; two magnet plates 8 are slidably installed on the inner side of the top of the main shell 1. The mutual repulsion of the magnet plates 8 can make the two positioning rods 9 slide outward, so that one end of the positioning rod 9 can be embedded in the rectangular holes on both sides of the protective cover 4 to limit the protective cover 4; a positioning rod 9 is fixed on one side of the two magnet plates 8, and the positioning rod 9 is used to fix the protective cover 4 at the topmost position.
[0031] In the present disclosure, Figure 1-Figure 4As shown, when the piston 7 slides down to the bottom, the protective cover 4 will be wrapped around the outside of the identification module 3, and when the piston 7 slides up to the top, the protective cover 4 will be separated from the identification module 3. When the device needs to be fixed for use, the base 2 can be stepped on with the foot and the handle 5 can be held to pull the protective cover 4 upward. During the upward movement, the protective cover 4 will also drive the piston 7 to move up synchronously through the connecting plate 6, so that the air pressure in the cavity at the bottom of the piston 7 and the large circular groove in the middle of the bottom of the base 2 can be reduced, so that the base 2 can be adsorbed on the ground, and when the protective cover 4 moves up to the top, the identification module 3 will be completely exposed to the outside, so the identification module 3 can be used to identify the passive electronic tag, and when the device is not in use, the two magnet plates 8 can be squeezed toward the middle position, and the positioning rods 9 will shrink into the main shell 1 and separate from the rectangular holes on both sides of the protective cover 4, so the protective cover 4 and the piston 7 will slide down to the bottom again, and the base 2 will be separated from the ground, and the protective cover 4 will also slide to the outside of the identification module 3 to protect it.
[0032] In the present disclosure, Figure 1-Figure 5 As shown, the rear inner wall and the left and right inner walls of the protective cover 4 are tightly attached to the outer wall of the main shell 1, and a vertical empty groove is set in the inner front of the protective cover 4, and the identification module 3 can be embedded in this empty groove after the protective cover 4 moves down. Therefore, the protective cover 4 can slide up and down stably on the outside of the main shell 1 without shaking, and the protective cover 4 can protect the identification module 3 after sliding to the outside of the identification module 3.
[0033] In the present disclosure, Figure 6 and Figure 7 As shown, a plate protruding upward is provided on the top of each magnet plate 8, and the adjacent magnetic poles of the two magnet plates 8 are of the same polarity. When the piston 7 slides to the top, one end of the positioning rod 9 can be embedded in the rectangular holes on the left and right sides of the protective cover 4. When the magnet plate 8 slides to the middle position, the positioning rod 9 will completely slide to the inside of the main shell 1. The protruding plate on the top of the magnet plate 8 can easily squeeze and push it toward the middle position, and can make one end of the positioning rod 9 embedded in the rectangular holes on both sides of the protective cover 4 to limit the protective cover 4.
[0034] In the present disclosure, Figure 3 and Figure 4 As shown, a cylindrical groove with an inner diameter equal to the outer diameter of the piston 7 is provided on the inner side of the bottom of the main shell 1, and the piston 7 can slide up and down in this cylindrical groove. When the device needs to be fixed for use, the base 2 can be stepped on and the handle 5 can be held to pull the protective cover 4 upward. During the upward movement, the protective cover 4 will also drive the piston 7 to move upward synchronously through the connecting plate 6, so that the air pressure in the cavity at the bottom of the piston 7 and the large circular groove in the middle of the bottom of the base 2 can be reduced, so that the base 2 can be adsorbed on the ground.
[0035] In the present disclosure, Figure 2-Figure 4 As shown, a large circular groove is provided in the middle of the bottom of the base 2, and the large circular groove is connected with the cylindrical groove on the inner side of the bottom of the main shell 1. When fixing the device, the main shell 1 can be placed on a flat ground by supporting the base 2, and then the position of the piston 7 can be adjusted to adjust the air pressure in the large circular groove in the middle of the bottom of the base 2, so that the device can be adsorbed and fixed by the base 2.
[0036] Embodiment 2, based on embodiment 1, as Figure 1-Figure 7 As shown, a long strip opening is provided on both sides of the main shell 1 for the connecting plate 6 to slide up and down, and the height of the piston 7 is greater than the height of the two long strip openings. A layer of rubber is also attached to the bottom of the base 2. Therefore, when the piston 7 slides to the top, the cavity at the bottom of the piston 7 will not be connected to the outside through the long strip openings on the left and right sides of the main shell 1, thereby ensuring the negative pressure state of the cavity at the bottom of the piston 7. The rubber at the bottom of the base 2 can improve the sealing of the contact surface with the ground, thereby ensuring that the base 2 can be firmly adsorbed on the ground during installation.
[0037] The working principle of this embodiment is as follows: when the device needs to be fixed for use, the main shell 1 is first placed on a flat ground with the support of the base 2, and then the base 2 can be stepped on with the foot and the handle 5 can be held to pull the protective cover 4 upward. During the upward movement, the protective cover 4 will also drive the piston 7 to move upward synchronously through the connecting plate 6, so that the air pressure in the cavity at the bottom of the piston 7 and the large circular groove in the middle of the bottom of the base 2 can be reduced, so that the base 2 can be adsorbed on the ground. During this process, another person can squeeze the two magnet plates 8 toward the middle position by hand, and then the two positioning rods 9 will completely slide to the inside of the main shell 1, and then align the rectangular holes on the left and right sides of the protective cover 4 with the positioning rods 9, and then the two magnets can be fixed. When the iron plate 8 is loosened, the two magnet plates 8 will push the positioning rod 9 to slide outward and embed into the rectangular holes on both sides of the protective cover 4 due to magnetic repulsion, so that the protective cover 4 can be fixed at the top position, and when the protective cover 4 moves to the top, the identification module 3 will also be completely exposed outward, so the identification module 3 can be used to identify the passive electronic tag. When the device is not in use, the two magnet plates 8 are squeezed toward the middle position. At this time, the positioning rod 9 will shrink into the main shell 1 and disengage from the rectangular holes on both sides of the protective cover 4. Therefore, the protective cover 4 and the piston 7 will slide down to the bottom again. At this time, the base 2 will be separated from the ground, and the protective cover 4 will also slide to the outside of the identification module 3 to protect it.
