[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0036] Example 1: An RFID reader / writer that is easy to fix, see [link to example]. Figures 1 to 4 It includes the RFID reader / writer body 1 and the suction cup 2;

[0037] Four suction cups 2 are arranged in a rectangular array on the bottom side of the outer shell of the RFID reader body 1; wherein, the suction cups 2 are connected to the bottom side of the outer shell of the RFID reader body 1 through a connecting structure 3.

[0038] This utility model, by setting up a suction cup 2 and a connecting structure 3, has the advantage of positioning the RFID reader / writer body 1 by adhering it to the desktop through the suction cup 2, thus ensuring the stable use of the RFID reader / writer body 1. It solves the problem that the RFID reader / writer is not securely attached to the desktop and is easily pulled to other positions, affecting its use.

[0039] Specifically, the connection structure 3 includes a sleeve 301 and a plug 302; the sleeve 301 is fixed to the bottom side of the outer shell of the RFID reader body 1; the plug 302 is fixedly connected to the suction cup 2; wherein, the plug 302 is inserted into the sleeve 301; wherein, the plug 302 and the sleeve 301 are positioned and engaged by the positioning component 303.

[0040] The positioning assembly 303 includes a positioning rod 3031, a pull block 3032, and a spring 3033. The positioning rod 3031 passes through a hole on the side of the sleeve 301. The inner end of the positioning rod 3031 is inserted into a hole on the side of the insertion post 302. The pull block 3032 is fixed to the outer end of the positioning rod 3031. The spring 3033 is sleeved on the positioning rod 3031 between the pull block 3032 and the outer wall of the sleeve 301. The two ends of the spring 3033 are fixedly connected to the pull block 3032 and the outer wall of the sleeve 301, respectively. The elastic coefficient of the spring 3033 shall be selected and used by the technical personnel in this field according to the actual situation.

[0041] This utility model, by setting up a sleeve 301, an insertion post 302, a positioning rod 3031, a pull block 3032, and a spring 3033, has the advantages of quick positioning after the sleeve 301 and the insertion post 302 are inserted, and convenient disassembly, so that the suction cup 2 can be installed or removed at any time, making it easy to use.

[0042] Furthermore, two guide bars 305 are symmetrically fixed on the outer ring wall of the insert post 302, and two guide grooves 3011 are symmetrically opened on the inner ring wall of the sleeve 301. The guide bars 305 and the guide grooves 3011 are inserted and cooperate.

[0043] This utility model, by setting guide strip 305 and guide groove 3011, has the advantage that the hole on the side of sleeve 301 and the hole on the side of insertion post 302 correspond through the guiding docking of guide strip 305 and guide groove 3011, which facilitates the insertion and positioning of positioning rod 3031.

[0044] Furthermore, the insertion end of the guide bar 305 is designed as a bevel 3051, which facilitates the insertion end of the guide bar 305 into the guide groove 3011.
