[0003] The device can be used in the production of handheld radio frequency identification devices, and can be quickly connected to the host to form an integrated device with reading and writing functions. However, the fixing structure strength of the device for identifying the sub-machine is low, and once it falls, it is easy for the sub-machine to fall off, so improvements are proposed.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-6 A handheld radio frequency identification device comprises an identification host 1, a support plate 101 is fixedly connected to the lower end surface of the identification host 1, an identification sub-machine 3 is movably plugged into the support plate 101, and the identification sub-machine 3 is fixedly connected to the support plate 101 through the cooperation of a limit assembly;

[0025] The limiting component includes a moving groove 104 opened in the middle of the supporting plate 101, and two groups of sliding blocks 7 are slidably connected inside the moving groove 104. The moving groove 104 is rotatably connected inside with a bidirectional screw rod 4 that penetrates the sliding block 7. The two groups of sliding blocks 7 are respectively sleeved on the two end threads of the bidirectional screw rod 4. A locking groove 301 is opened on the inner end surface of the identification sub-machine 3, and the outer end surfaces of the two groups of sliding blocks 7 are fixedly connected with locking blocks 701. The locking blocks 701 are slidably inserted into the locking groove 301. The movement of the sliding block 7 and the locking block 701 is driven by the rotation of the bidirectional screw rod 4. When the identification sub-machine 3 is engaged and fixed with the supporting plate 101, the locking block 701 is moved and inserted into the locking groove 301, so that the identification sub-machine 3 is fixed. The connection strength between the main machine and the sub-machine is high. When the protection device falls at a certain height, the identification sub-machine 3 will not be separated from the identification host 1, thereby maintaining the stability of the device and having good safety.

[0026] A slide groove 105 is provided inside the support plate 101, and one end of the bidirectional screw rod 4 is fixedly connected to a driving rod 401 extending into the slide groove 105, and a slide rod 5 is slidably connected inside the slide groove 105. An inner end of the slide rod 5 is fixedly connected to a contact plate 501, and an inner end face of the contact plate 501 is fixedly connected to a driving plug-in 502. A driving card slot 402 that cooperates with the driving plug-in 502 is provided on the outer end face of the driving rod 401, and the driving plug-in 502 is movably inserted into the inside of the driving card slot 402. When the driving plug-in 502 is inserted into the driving card slot 402, the rotation of the slide rod 5 will drive the rotation of the driving rod 401, thereby driving the bidirectional screw rod 4 to rotate.

[0027] A tension spring 6 is sleeved on the outer end surface of the slide rod 5, an inner end of the tension spring 6 is fixedly connected to the abutment sheet 501, and an outer end of the tension spring 6 is fixedly connected to the support plate 101. The drive plug-in 502 is disengaged from the drive slot 402 by the action of the tension spring 6, thereby preventing accidental touch.

[0028] One outer end of the slide rod 5 extends to the outside of the support plate 101 and is fixedly connected to an external knob 503. A groove is provided on the outer end face of the support plate 101 to fix the external knob 503 so that it cannot move outward. The external knob 503 is narrow in the middle and wide in the inside. The groove can limit the wide part of the external knob 503 from passing through. In this way, the external knob 503 is fixed so that it will not pop out under the action of the tension spring 6, and at the same time will not affect the inward movement of the external knob 503.

[0029] The inner end surface of the support plate 101 is provided with a connecting piece 103 electrically connected to the identification host 1, and the inner end surface of the identification sub-machine 3 is provided with a connecting groove 302 that cooperates with the connecting piece 103. The connecting piece 103 is movably inserted into the inside of the connecting groove 302. The identification host 1 and the identification sub-machine 3 are electrically connected through the cooperation of the connecting groove 302 and the connecting piece 103, so there is no need to add a separate Bluetooth or wireless communication module.

[0030] The lower end surface of the identification host 1 is fixedly connected with a hand grip 2 , and the lower end surface of the hand grip 2 is provided with a charging port 201 . The hand grip 2 is provided to facilitate the use of the device, and the device can be charged through the charging port 201 .

[0031] A reinforcing rib 102 is fixedly connected to the lower end surface of the identification host 1, and one end of the reinforcing rib 102 is fixedly connected to the support plate 101. The connection strength of the support plate 101 is increased by providing the reinforcing rib 102, which has better safety.

[0032] Working method: When working, insert the identification sub-machine 3 into the support plate 101, and through the cooperation of the connecting piece 103 and the connecting groove 302, the identification host 1 and the identification sub-machine 3 are connected to each other, and there is no need to add a Bluetooth or wireless communication module separately. At this time, press the external knob 503 inward to insert the drive plug-in 502 into the driving card slot 402. By rotating the external knob 503, the rotation of the two-way screw rod 4 can be driven. The rotation of the two-way screw rod 4 can drive the two groups of sliding blocks 7 and the locking block 701 to move in opposite directions, insert and engage in the locking groove 301. The fixing of the two groups of sliding blocks 7 and the locking block 701 greatly improves the fixing strength of the identification sub-machine 3. When the protection device falls from a certain height, the identification sub-machine 3 will not be separated from the identification host 1, thereby maintaining the stability of the device and having good safety.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
