[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] This embodiment provides an auxiliary device for a handheld reader / writer, such as Figure 1-5As shown, the auxiliary device includes an arm frame 1, the end surface of the arm frame 1 is installed with a quick-release structure 2, and the reader body 3 is fixedly installed on the quick-release structure 2;

[0024] The quick-release structure 2 includes a fixed box 21 fixedly installed on the end face of the arm frame 1, and a mounting frame 22 is symmetrically installed on the front and rear sides of the bottom of the inner cavity of the fixed box 21. A limiting slide 23 is slidably installed on the mounting frame 22, and springs 24 connected to the sliding part 231 are installed on both sides of the inner cavity side wall of the mounting frame 22. A driving rod 25 is installed on the side wall of the limiting slide 23, and a T-shaped block 26 is slidably installed in the inner cavity of the fixed box 21. Two hooks 27 are installed on the front and rear sides of the T-shaped block 26.

[0025] When in use, the two driving rods 25 are pressed synchronously in the direction close to the T-shaped block 26. The two driving rods 25 drive the corresponding limiting slides 23 to move, and the limiting slides 23 slide in the slide grooves 221 with the sliding parts 231 on the left and right sides. The limiting slide 23 moves with the two triangular clamping blocks 232 close to the spring 24 and separates from the corresponding hooks 27. The triangular clamping blocks 232 no longer clamp the hooks 27. The handheld part 31 can be held and moved upward with the T-shaped block 26. The T-shaped block 26 moves with the hook 27, and the reader body 3 can be quickly removed. This avoids the problem that the existing auxiliary device uses a U-shaped mounting block and mounting bolts to install the reader body on the auxiliary device. This installation method is inconvenient for later disassembly. When the user needs to hold the reader 3 by hand for use, the reader 3 can be quickly removed from the auxiliary device, thereby improving the flexibility of use of the auxiliary device.

[0026] In this embodiment, a through hole 211 is formed on the fixing box 21 and corresponds to the driving rod 25. The fixing box 21 is slidably connected to the driving rod 25 through the through hole 211. Sliding portions 231 are provided on the left and right sides of the limiting slide 23. Triangular clamping blocks 232 are installed on the side walls of the limiting slide 23 and correspond to the hooks 27. A sliding groove 221 is formed on the inner side wall of the mounting frame 22 and is slidably connected to the triangular clamping blocks 232.

[0027] The inner side wall of the mounting frame 22 is provided with a slide groove 221 slidably connected to the triangular clamping block 232, which can limit the range of motion of the limiting slide 23 so that it can only move forward and backward, and the triangular clamping block 232 is engaged or separated with the hook 27, thereby realizing the rapid disassembly and assembly of the arm frame 1;

[0028] In this embodiment, a handheld portion 31 fixedly connected to the end face of the T-shaped block 26 is installed at the bottom of the reader body 3, and straps 10 are installed at the lower end of the arm frame 1 and on the front and rear sides. The movable ends of the front and rear straps 10 are connected by Velcro.

[0029] Example 2

[0030] Unlike Example 1, the arm frame of the existing auxiliary device does not have a heat dissipation function. When the auxiliary device is used in hot weather, the arm frame and the sponge block will be very hot when tied to the arm. Therefore, a fixing cylinder 4 is installed on the left and right sides of the end surface of the arm frame 1, and a mounting frame 41 is installed on the inner wall of the fixing cylinder 4. A fan 5 is installed at the bottom center of the mounting frame 41. A switch 6 is hidden on the end surface of the arm frame 1, and a battery 7 is installed on the arm frame 1 through a groove 13;

[0031] When in use, the battery 7 provides power to the fan 5, and the user activates the fan 5 through the switch 6. The fan 5 blows external air through the fixed tube 4 and the air inlet 12 to the user's arm, accelerating the air flow at the arm and achieving heat dissipation of the arm. This avoids the problem that the arm frame of the existing auxiliary device does not have a heat dissipation function and the arm frame and the sponge block will be very hot when the auxiliary device is used in hot weather, thereby improving the comfort of use of the auxiliary device.

[0032] In this embodiment, an air duct 11 is provided on the inner wall of the arm frame 1, an air inlet 12 is provided on the arm frame 1 and corresponds to the fixing tube 4, and a protective plate 14 is installed on the arm frame 1 through a groove 13; rubber pads 8 are installed on the inner wall of the arm frame 1 and at the front and back, and a plurality of heat dissipation holes 9 are provided on the arm frame 1 and the rubber pads 8 respectively;

[0033] Among them, a number of heat dissipation holes 9 are correspondingly opened on the arm frame 1 and the rubber pad 8, so that the arm is ventilated with the outside, the air permeability of the arc-shaped part of the arm frame 1 is increased, the heat dissipation capacity of the arm frame 1 is improved, and the auxiliary device is comfortable to use even in hot weather.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and concept of the present invention, which should be covered by the protection scope of the present invention.
