As shown in fig. 1 to 6, the rfid handheld device of the present application includes a host 10, an antenna 20, and a limiting structure. One end of the antenna 20 is connected with the host 10, the antenna 20 can rotate relative to the host 10, the antenna 20 has a first working position and a second working position, and when the antenna 20 is switched from the first working position to the second working position, an included angle between the antenna 20 and the host 10 is reduced; the spacing structure is used to maintain the antenna 20 in the first and/or second operating positions.

When the rfid handheld device of the present application is used, since the antenna 20 can rotate relative to the host 10, and the antenna 20 has a first working position and a second working position relative to the host 10, the relative position between the antenna 20 and the host 10 can be adjusted according to different requirements. Therefore, when the rfid handheld device needs to be stored, the antenna 20 can be switched from the first working position to the second working position, so as to reduce the space occupied by the rfid handheld device, thereby facilitating storage. Moreover, since the rfid handheld device further has a limiting structure, the antenna 20 can be kept at the first working position or the second working position by the limiting structure, so as to ensure the stability of the rfid handheld device during use. Therefore, the radio frequency identification handheld device effectively solves the problem that the radio frequency identification handheld device in the prior art is poor in use performance.

It should be noted that, in the present application, the position of the antenna 20 relative to the host 10 is realized by the mechanical structure of the position limiting structure, that is, in the present application, no magnet or motor is needed to provide power during the process of switching the antenna 20 between the first operating position and the second operating position.

Optionally, when the antenna 20 is in the first operating position, an included angle between the antenna 20 and the host 10 is greater than or equal to 60 degrees and less than or equal to 90 degrees. That is, when the antenna 20 is in the first operating position, the antenna 20 is disposed at an angle with respect to the main body 10.

In one embodiment of the present application, when the antenna 20 is in the first operating position, the antenna 20 is perpendicular to the host 10; when the antenna 20 is in the second operating position, the antenna 20 is parallel to the host 10. Therefore, in the present embodiment, it is possible to reduce the included angle between the antenna 20 and the host computer 10 when the antenna 20 is switched from the first operating position to the second operating position. Moreover, in the present embodiment, when the antenna 20 is in the first operating position, the antenna 20 and the host 10 are perpendicular to each other. Therefore, when the antenna 20 is located at the first working position, the antenna 20 and the host 10 can be kept in a vertical state under the action of the limiting structure, so that the long-term use requirement of the radio frequency identification handheld device can be met. And, when the radio frequency identification handheld device is needed, only the antenna 20 needs to be switched to the second working position.

Optionally, the limiting structure includes a first limiting structure and a second limiting structure, and the first limiting structure is configured to keep the antenna 20 at the first working position; the second position limiting structure is used to maintain the antenna 20 in the second operating position. At least one of the first limiting structure and the second limiting structure is in limiting fit in a clamping groove 30 and a buckle 40 mode. It should be noted that, in the present application, the position limiting structure may be provided only on the main unit 10 and the antenna 20 has a structure cooperating with the position limiting structure, or may be provided only on the antenna 20 and the main unit 10 has a structure cooperating with the position limiting structure. Of course, it is also possible that one part of the position limiting structure is disposed on the main body 10, and the other part is disposed on the antenna 20. Therefore, the specific arrangement mode of the limiting structure can be designed according to the actual use condition. That is, in the present application, the first position-limiting structure may be separately disposed on the main unit 10 or the antenna 20, or may be disposed on both the main unit 10 and the antenna 20, and the arrangement position scheme of the second position-limiting structure is the same as that of the first structure. At least the other of the first and second position limiting structures has an operation element, and the operation element is used to maintain the position of the antenna 20 with respect to the host computer 10 and/or release the position of the antenna. It should be noted that, in the present application, the operating element may be a leg or may be a structure capable of being locked and unlocked.

Specifically, the host 10 has a limiting groove 11, at least one part of the second limiting structure is movably disposed inside the limiting groove 11, at least another part of the second limiting structure protrudes out of the host 10 and can slide relative to the host 10, the antenna 20 has a limiting protrusion 21 matched with the second limiting structure, the limiting protrusion 21 has a limiting hole 211, when the antenna 20 is located at the second working position, the limiting protrusion 21 extends into the limiting groove 11, and a limiting head of the second limiting structure extends into the limiting hole 211 and keeps the antenna 20 at the second working position. In one embodiment of the present application, the second limiting structure comprises a limiting block 50 and a spring 60. One end of the limiting block 50 is provided with a limiting head, and the other end of the limiting block 50 is used as an operating part and protrudes out of the host 10; one end of the spring 60 abuts against the limiting block 50, and the other end of the spring 60 abuts against the inner side wall of the host 10. In addition, in the present application, in the process that the antenna 20 is switched from the first working position to the second working position, the limiting protrusion 21 gradually extends into the limiting groove 11 and presses the limiting head, and after the antenna 20 is switched to the second working position, the limiting block 50 can move towards the limiting protrusion 21 under the action of the spring 60, and the limiting head can extend into the limiting hole 211, so as to limit the antenna 20, and the antenna 20 is kept at the second working position. When the antenna 20 needs to be switched from the second working position to the first working position, the limiting head can exit the limiting hole 211 only by pushing the operating element in a direction away from the antenna 20, so that the antenna 20 is unlocked, and the antenna 20 can be switched from the second working position to the first working position.

Specifically, the host 10 in the present application includes a body portion 12 and a mounting bracket 13. The mounting bracket 13 is detachably arranged on the body part 12, the antenna 20 is arranged on the mounting bracket 13, and the body part 12 or the mounting bracket 13 is provided with a limiting structure.

Alternatively, the body portion 12 has a mounting groove 121, the mounting bracket 13 is disposed inside the mounting groove 121, the groove bottom of the mounting groove 121 has a limiting groove 122, and the mounting bracket 13 has a limiting boss 131 engaged with the limiting groove 122. This arrangement prevents the mounting bracket 13 from being accidentally detached from the main body 12, thereby ensuring stability between the mounting bracket 13 and the main body 12. And, by so arranging, it is also possible to provide a positioning action for the mounting of the mounting bracket 13.

In one embodiment of the present application, the mounting bracket 13 has two mounting bosses 132, the antenna 20 has a hinge 22, and the host 10 further includes a latch 70 and a torsion spring 80.
