[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] See also Figure 1-5 The utility model provides a technical solution: a portable reader / writer, comprising a positioning frame 1, an operation panel 11 is installed in the positioning frame 1, a radio frequency reader 12 is fixedly installed on the front end surface of the positioning frame 1, a scanner 13 is fixedly installed on the front end surface of the radio frequency reader 12, and the radio frequency reader 12 and the scanner 13 are distributed at right angles, a through cavity 22 and a positioning cavity 21 that match each other are respectively opened on the lower end surface of the positioning frame 1 and the lower end surface of the operation panel 11, a positioning card plate 23 that is plugged into the positioning cavity 21 is rotatably installed in the through cavity 22, and the positioning cavity 21 and the positioning card plate 23 are arranged in a sector shape that matches each other, and a handle 2 that contacts the positioning card plate 23 is slidably installed on the lower end surface of the positioning frame 1.

[0026] Working principle: The radio frequency reader 12 and the scanner 13 are set to read the IC card and the bar code respectively, and the operation panel 11 is set to control the radio frequency reader 12 and the scanner 13, and to display and operate the information read by the radio frequency reader 12 and the scanner 13;

[0027] When the operation panel 11 is inserted and installed in the positioning frame 1, the handle 2 can be pulled backward at the lower end of the positioning frame 1 so that the handle 2 contacts the positioning card plate 23. Through the contact effect between the two, the positioning card plate 23 can be driven to rotate in the through cavity 22, so that the positioning card plate 23 is inserted into the positioning cavity 21, thereby achieving the effect of positioning the operation panel 11 in the positioning frame 1, so that the operation panel 11 can be inspected and replaced in the positioning frame 1.

[0028] Example 2

[0029] A first limit block 24 and a second limit slider 25 that match each other in position are fixedly installed on the lower side of the outer end of the through cavity 22 and the upper side of the outer periphery of the positioning card plate 23, respectively. A positioning cavity 26 and a positioning hole 27 that match each other in position are provided at the joint between the handle 2 and the positioning frame 1. A latch 28 that is plugged into the positioning hole 27 is provided in the positioning cavity 26, and a spring 281 is fixedly installed between the latch 28 and the positioning cavity 26. A plug rod 29 that is plugged into the lower end of the latch 28 is fixedly installed in the positioning cavity 26, and the spring 281 is sleeved on the outer periphery of the plug rod 29. The outer end of the positioning cavity 26 is communicated with the outside world, and a dial plate 282 is fixedly installed on the outer periphery of the plug rod 29.

[0030] Through the contact effect between the first limiting block 24 and the second limiting slider 25, the rotation range of the positioning card plate 23 can be controlled in the through cavity 22 to avoid interference between the positioning card plate 23 and the handle 2, thereby ensuring that the handle 2 can drive the positioning card plate 23 to rotate;

[0031] When the handle 2 needs to be slid, the lever 29 is pressed downward by the lever plate 282, so that the lever 29 and the positioning hole 27 are separated from each other, and the connection between the handle 2 and the positioning frame 1 is released, so that the handle 2 can be slid forward at the lower end of the positioning frame 1;

[0032] When the handle 2 is slid backward and the positioning cavity 26 and the positioning hole 27 are aligned with each other, the spring 281 can restore its deformation and drive the latch 28 to return to its original position, so that the latch 28 is plugged into the positioning hole 27, thereby achieving the effect of positioning the connection between the handle 2 and the positioning frame 1.

[0033] Example 3

[0034] A first limit rotating seat 3 is fixedly installed on the front end surface of the positioning frame 1, and second limit rotating seats 31 that are rotatably matched with both sides of the first limit rotating seat 3 are fixedly installed on both sides of the rear end of the radio frequency reader 12. A first positioning tooth hole 32 and a second limit tooth hole 33 are respectively opened at the joint of the first limit rotating seat 3 and the second limit rotating seat 31. A positioning gear rod 34 is inserted and installed in the first positioning gear hole 32 and the second position limiting gear hole 33. A motor 35 is fixedly installed in the first limit rotating seat 3, and a threaded rod 36 that is threadably matched with the positioning gear rod 34 is fixedly installed on the outer end of the motor 35 through its output shaft.

[0035] Through the rotational cooperation between the first position-limiting rotating seat 3 and the second position-limiting rotating seat 31, the RF reader 12 can be rotated at the front end of the positioning frame 1 to achieve the effect of contracting and expanding the device;

[0036] After the angle of the RF reader 12 is adjusted, the motor 35 is started through the operation panel 11. The motor 35 drives the threaded rod 36 to rotate through its output shaft. The first positioning tooth hole 32 is plugged in with the positioning gear rod 34 to limit the movement direction of the positioning gear rod 34. The rotating threaded rod 36 can drive the positioning gear rod 34 to move through the threaded cooperation between the positioning gear rod 34, so that the positioning gear rod 34 is plugged in with the first positioning tooth hole 32 and the second limiting tooth hole 33, so as to achieve the effect of positioning the connection between the first limiting rotating seat 3 and the second limiting rotating seat 31.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
