[0033] Refer to Figure 2 - Figure 4 For, a control groove 33 is opened on the inner wall of the left end of the mounting base 2. A starting block 34 is slidably connected to the inner wall of the control groove 33. The shape of the starting block 34 is approximately semi-circular. The shape of the starting block 34 fits the shape of the control groove 33. Through the shape setting of the starting block 34, it is ensured that the starting block 34 can contact the outer wall of the first adjusting rod 32 as much as possible without affecting the first rotating rod 31, so as to facilitate achieving the expected effect. The left end of the starting block 34 is rotatably connected with a screw 35. The diameter of the screw 35 is smaller than the thickness of the starting block 34. The outer wall of the screw 35 penetrates and is threadedly connected to the left inner wall of the mounting base 2.

[0034] Refer to Figure 2 - Figure 4, an installation groove 36 is provided on the inner wall of the first adjusting rod 32. A first control board 37 is slidably connected to the inner wall of the installation groove 36. A first pushing block 38 is fixedly connected to the right end of the first control board 37. The right end of the first pushing block 38 penetrates through the inner wall of the first adjusting rod 32. The left end of the first control board 37 is elastically connected to the inner wall of the installation groove 36 through a first spring 39. One end of the first spring 39 is fixedly connected to the left end of the first control board 37, and the other end of the first spring 39 is fixedly connected to the inner wall of the installation groove 36. A first clamping ring 310 is fixedly connected to the right inner wall of the mounting seat 2. The inner diameter of the first clamping ring 310 is larger than the outer diameter of the first pushing block 38. A first clamping groove 311 is provided on the outer wall of the first adjusting rod 32. The shape of the first clamping ring 310 fits the shape of the first clamping groove 311.

[0035] Refer to Figure 2 , Figure 3 and Figure 5 , a second rotating rod 312 is rotatably connected to the upper inner wall of the first adjusting rod 32. The second rotating rod 312 penetrates through the inner wall of the first control board 37. A second adjusting rod 313 is penetrated and slidably connected to the outer wall of the second rotating rod 312. The length of the second adjusting rod 313 is shorter than the length of the hollow position in the middle of the top end of the first adjusting rod 32. The middle of the end of the second adjusting rod 313 away from the first adjusting rod 32 is hollow. An installation groove 314 is provided at the left end of the second adjusting rod 313. A second control board 315 is slidably connected to the inner wall of the installation groove 314. The right end of the second control board 315 is elastically connected to the inner wall of the installation groove 314 through a second spring 317. One end of the second spring 317 is fixedly connected to the right end of the second control board 315, and the other end of the second spring 317 is fixedly connected to the inner wall of the installation groove 314.

[0036] Refer to Figure 2 , Figure 3 and Figure 5 , a third adjusting rod 322 is penetrated and slidably connected to the outer wall of the third rotating rod 321. The length of the third adjusting rod 322 is shorter than the length of the hollow position inside the second adjusting rod 313. By comparing the lengths with the hollow positions, it is ensured that the second adjusting rod 313 can be accommodated in the inner wall of the first adjusting rod 32, and the third adjusting rod 322 can be accommodated inside the second adjusting rod 313, achieving the effect of convenient storage. The left outer wall of the third adjusting rod 322 is rotatably connected to the right end of the second control board 315. A third clamping ring 323 is fixedly connected to the right inner wall of the second adjusting rod 313. A third clamping groove 324 is provided on the right outer wall of the third adjusting rod 322. A fixing device 4 is provided at the front end of the third adjusting rod 322. The fixing device 4 is used to fix the code reader, and this device is an existing technology and can be realized by those skilled in the art, so it will not be described in detail in this case.

[0037] Refer to Figure 1 Figure 1 , a collision prevention component 5 is provided below the mounting plate 1. The collision prevention component 5 includes a slide bar 51. The shape of the slide bar 51 is cylindrical. The outer wall of the slide bar 51 penetrates and is slidably connected to the inner wall of the mounting plate 1. A bottom plate 52 is fixedly connected to the bottom end of the slide bar 51. A device for connecting to a desktop or other object is provided at the lower end of the bottom plate 52, and this device is a prior art and can be implemented by those skilled in the art, so it will not be described in detail in this case. An elastic telescopic rod 53 is hinged to the top end of the bottom plate 52. One end of the elastic telescopic rod 53 away from the bottom plate 52 is hinged to the bottom end of the mounting plate 1. When the elastic telescopic rod 53 is in the initial state, the top end and the bottom end are not in the same vertical plane. Through the position setting of the elastic telescopic rod 53, it is ensured that the elastic telescopic rod 53 has a certain degree of inclination, so as to ensure that when the mounting plate 1 moves up and down under force, it will not be hindered greatly by the elastic telescopic rod 53.

[0038] Working principle: When in use, the staff first adjusts the positions of the first adjusting rod 32, the second adjusting rod 313, and the third adjusting rod 322 according to needs, so that the code reader can be adjusted to the required position. After the position adjustment is completed, the staff rotates the screw rod 35, so that the screw rod 35 moves to the right during rotation, thereby making the screw rod 35 push the starting block 34 to move to the right.

[0039] During the process of the starting block 34 moving to the right, the starting block 34 pushes the first adjusting rod 32 to move to the right, so that the inner wall of the first slot 311 contacts the first snap ring 310, so that the position of the first adjusting rod 32 is fixed, so that the first adjusting rod 32 cannot continue to rotate.

[0040] At the same time, during the process of the first adjusting rod 32 moving to the right, since the first push block 38 cannot move further after moving to contact the inner wall of the mounting seat 2, at this time, the first push block 38 moves to the left relative to the first adjusting rod 32 moving to the right, so that the first control board 37 moves to the left relative to the first adjusting rod 32, so the first control board 37 pushes the second adjusting rod 313 to move to the left.

[0041] After the second adjusting rod 313 moves leftward, the inner wall of the second card slot 319 moves to a position in contact with the outer wall of the second snap ring 318. Therefore, the second adjusting rod 313 cannot continue to rotate. At the same time, during the process of the second adjusting rod 313 moving leftward, since the second push block 320 cannot move further after moving into contact with the inner wall of the first adjusting rod 32, the second push block 320 moves rightward relative to the second adjusting rod 313 at this time. Therefore, the second control board 315 moves rightward relative to the second adjusting rod 313. Thus, the second adjusting rod 313 pushes the third adjusting rod 322, and makes the outer wall of the third snap ring 323 contact with the inner wall of the third card slot 324, so that the third adjusting rod 322 cannot continue to rotate. Therefore, during use, the position of the code reader can be fixed and will not produce a large displacement.

[0042] When an external force acts on the code reader, since the elastic telescopic rod 53 can bend, there is space for the code reader to move up and down. Therefore, the code reader will not cause the adjusting mechanism 3 to tip over, but will drive the mounting base 2 to move up and down through the adjusting mechanism 3. When the external force disappears, the code reader is automatically adjusted back to its original position under the drive of the elastic telescopic rod 53.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
