[0052] It should be noted that the outer side of the nut 135 is hexagonal, which is more convenient for workers to exert force to remove the nut 135, and improves the efficiency of workers in disassembling the nut 135.

[0053] It can be understood that the distance between the first horizontal plate 1311 and the second horizontal plate 221 matches the diameter of the threaded rod 133, so that the threaded rod 133 is clamped between the first horizontal plate 1311 and the second horizontal plate 221, improving the reliability of the fastening part 130 clamping the radio frequency card reader 200.

[0054] In a possible implementation, the fastening part 130 further comprises:

[0055] The first stopper 137 is arranged at one end of the threaded segment away from the smooth surface segment, and the nut 135 and the pressing plate 136 are located between the annular block 134 and the first stopper 137.

[0056] The first stopper 137 is arranged at one end of the threaded segment away from the smooth surface segment, and the nut 135 and the pressing plate 136 are located between the annular block 134 and the first stopper 137.

[0057] It can be understood that when installing, the bolt 135 and the pressing plate 136 are located at one end close to the first stopper 137, and the first vertical plate 1312 and the second vertical plate 222 are aligned to form an accommodation space, the height of the accommodation space matches the outer diameter of the threaded rod 133, so that the accommodation space clamps the threaded rod 133, and the annular block 134 of the threaded rod 133 abuts against the first vertical plate 1312 and the second vertical plate 222. At this time, the fixing pin 132 penetrates the first horizontal plate 1311, the annular block 134 and the second horizontal plate 221, and the setting of the fixing pin 132 can avoid the swing of the threaded rod 133 in the accommodation space, improving the stability of the threaded rod 133.

[0059] The fastening part 130 can include two threaded rods 133, three threaded rods 133, or more threaded rods 133. The more threaded rods 133, the more stable the fixing of the video card reader 200, but more threaded rods 133 affect the disassembly efficiency, and thus affect the replacement and maintenance efficiency of the video card reader 200. Therefore, two threaded rods 133 or three threaded rods 133 can be considered comprehensively. In this embodiment, two threaded rods 133 are taken as an example for description, which is only an example.

[0060] It should be noted that when two threaded rods 133 are provided, the axes of the two threaded rods 133 are arranged in parallel, and a third vertical plate 1313 is arranged between the two threaded rods 133.

[0063] The first vertical plate 1312 is provided with a groove on the side facing the second vertical plate 222, and the second vertical plate 222 is provided with a protruding block on the side facing the first vertical plate 1312. The arrangement of the groove and the protruding block can directly position the radio frequency card reader 200, and the fixing bolt 132 can directly pass through the first horizontal plate 1311 and the second horizontal plate 221, thereby realizing the stable connection between the fastening part 130 and the radio frequency card reader 200 and improving the reliability and simplicity of the connection of the fixing bolt 132.

[0064] Similarly, the first vertical plate 1312 can also be provided with a protruding block on the side facing the second vertical plate 222, and the second vertical plate 222 is provided with a groove on the side facing the first vertical plate 1312 to achieve such positioning. It can be understood that the first vertical plate 1312 can also be provided with a protruding block and a groove on the side facing the second vertical plate 222, and correspondingly, the second vertical plate 222 is provided with a groove and a protruding block on the side facing the first vertical plate 1312, and the positioning of the connecting plate 220 and the first fixing block 131 is realized by the groove and the protruding block, which is more convenient for the fixing bolt 132 to directly connect the first horizontal plate 1311 and the second horizontal plate 221.

[0065] Figure 3 A schematic view of a support portion according to an embodiment of the application.

[0066] In a possible implementation manner, as shown in Figure 3 The middle section of the support portion 110 is provided with a sliding rail 111, which is located on the side of the support portion 110 away from the radio frequency card reader 200. Two rows of barriers are arranged oppositely in the sliding rail 111, and the two rows of barriers are located on both sides of the width direction of the sliding rail 111. The barriers include a plurality of second blocking blocks 112, and a gap 113 is arranged between adjacent two second blocking blocks 112. The connecting portion 120 moves in the sliding rail 111, and the connecting portion 120 is used for clamping in the gap 113.

[0067] The sliding rail 111 can facilitate the connecting portion 120 to drive the fastening portion 130 to move on the sliding rail 111, improve the use flexibility of the fixing and adjusting device 100, and flexibly adjust the height of the scanning head of the radio frequency card reader, that is, different positions, so that the application range is wider, and the device is suitable for use by different workers and is more convenient to use. It can be understood that the mechanical structure of the application can reduce the cost of the fixing and adjusting device 100, thereby improving the economy of the fixing and adjusting device 100; at the same time, the structure is simple, and it is not necessary to additionally set up a supplementary power supply, and it is not necessary to frequently overhaul and maintain, thereby reducing the overhaul and maintenance cost.

[0068] It needs to be explained that a rectangular groove is arranged in the middle section of the support part 110, and the groove is the slide rail 111. The slide rail 111 is provided with a shielding object at both ends in the width direction, each column of shielding objects includes a plurality of second blocks 112, that is, the second blocks 112 form a plurality of rows and two columns of arrangement forms, and the two columns of second blocks 112 are arranged opposite to each other, and the gap 113 is formed between the adjacent two rows of second blocks 112. It can be understood that when the height of the radio frequency card reader 200 needs to be adjusted, the elements in the compression connecting part 120 move between the two columns of second blocks 112, and when reaching the required position, the elements in the compression connecting part 120 are loosened, so that the elements can be clamped in the gap 113 formed by the two rows of second blocks 112, and the two rows of second blocks 112 play a clamping and fixing role on the compression connecting part 120.

[0069] In the embodiment, four second blocks 112 are included in each column of shielding objects, and three, five, six or the like second blocks 112 can also be arranged in each column of shielding objects, which can be selected as required, and will not be described in detail.

[0070] Figure 4 It is an internal schematic view of the connecting part according to an embodiment of the utility model; Figure 5 It is a connecting schematic view of the first driving block and the second driving block according to an embodiment of the utility model.

[0071] In a feasible implementation manner, as shown in Figure 4 and Figure 5 , the connecting part 120 includes:

[0072] The sliding block 121 is sleeved on the support part 110;

[0073] The pair of first driving blocks 122 are oppositely arranged on the outer side of the sliding block 121;

[0074] The pair of second driving blocks 123 are connected with the first driving blocks 122, and at least part of the second driving blocks 123 are located in the sliding block 121;

[0075] The telescopic rod 124 is arranged between the pair of second driving blocks 123.

[0076] Among them, the connecting part 120 includes the sliding block 121, the sliding block 121 is fixedly connected with the fastening part 130, the sliding block 121 is provided with a first through hole matched with the support part 110, and the size of the first through hole is slightly larger than the size of the support part 110, that is, the first through hole is in clearance fit with the support part 110, so that the sliding block 121 can smoothly reciprocate on the slide rail 111 of the support part 110.

[0077] It should be noted that the slider 121 is further provided with a second through hole, and the diameter of the second through hole is substantially perpendicular to the diameter of the first through hole. A pair of first driving blocks 122 are located on the outer side of the slider 121, and the pair of first driving blocks 122 are oppositely arranged. The second driving block 123 is fixedly connected with the first driving block 122. The size of the first driving block 122 is larger than the size of the second through hole. The second driving block 123 is in clearance fit with the second through hole, so as to facilitate the staff to press the pair of first driving blocks 122, and then drive the second driving block 123 to compress the telescopic rod 124. After compression, it can move between the two rows of second stop blocks 112 to reach the required position. When the pair of first driving blocks 122 are released, the pair of second driving blocks 123 can be clamped in the gap 113 between the two rows of second stop blocks 112 under the action of the reverse force of the telescopic rod 124, so as to realize the fixation of the slider 121, and then realize the fixation of the radio frequency card reader 200 at different height positions. As can be seen from the above, the width of the second driving block 123 matches the gap 113, and the second driving block 123 can be clamped between the two rows of second stop blocks 112. At the same time, the side of the first driving block 122 away from the second driving block 123 can be provided with anti-skid lines or anti-skid rubber, so as to facilitate the staff to press, and avoid hand slipping.

[0078] It can be understood that the parallel and perpendicular mentioned in the present application can also have a certain error, which is the processing common sense known in the art, and therefore will not be repeated.

[0079] In a possible implementation, the connecting part 120 further comprises:

[0080] The clamping block 125 is arranged at the end of the second driving block 123 away from the first driving block 122. The clamping block 125 is L-shaped, and the clamping block 125 and the second driving block 123 form a bending part 126. The bending part 126 abuts against the second stop block 112 or is clamped in the gap 113.

The bending part 126 abuts against the second stop block 112 or is clamped in the gap 113.

[0082] It can be understood that when the telescopic rod 124 is compressed, the distance between the two bending parts 126 is not greater than the distance between the two rows of second stop blocks 112, so that the connecting part 120 can move smoothly between the two rows of second stop blocks 112; and when the telescopic rod 124 is not compressed, the distance between the two bending parts 126 matches the width of the slide rail 111, which can enable the clamping block 125 to be clamped in the gap 113 and ensure the stability of the connecting part 120, thereby avoiding shaking of the connecting part 120.
