[0028] It should be noted that the glass plate A2 can shield the camera in the scanning opening 11, when the surface of the glass plate A2 is attached with a large amount of dust and the scanning work of the gun body 1 is affected, the glass plate B21 is manually rotated, the limiting plate 23 is clamped into the limiting groove 24, and the glass plate B21 is rotated to the parallel state with the glass plate A2, the maximum rotating angle of the glass plate A2 and the glass plate B21 can be limited through the cooperation of the limiting plate 23 and the limiting groove 24, and in the rotating process of the glass plate A2 and the glass plate B21, the torsion spring 22 is compressed and starts to tighten, then pushes the glass plate B21, and the glass plate B21 is pushed into the scanning opening 11 through the limiting opening 12, at this time, the scanning opening 11 is shielded by the clean glass plate B21, and after the glass plate A2 is pushed out through the scanning opening 11, the torsion spring 22 starts to rebound and drives the glass plate A2 to rotate towards the gun body 1 until the glass plate A2 is attached to the sponge pad 31 on the gun body 1.
[0029] In the embodiment of the utility model, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 The mounting frame 3 is fixedly connected with a plurality of uniformly distributed sponge pads 31, the sponge pads 31 are attached to the surface of the gun body 1, the glass plate B21 is located in the mounting frame 3 on the same side, the two sides of the glass plate B21 are attached to the sponge pads 31 and the cotton strips 42 on the same side, respectively, a sliding groove is arranged in the inner wall of the mounting frame 3, the baffle 4 is slidably connected between the sliding grooves in the inner wall of the mounting frame 3, the side of the baffle 4 close to the gun body 1 is fixedly connected with a limiting frame 41, and the limiting frame 41 is embedded with a cotton strip 42.
[0030] It should be noted that after the glass plate A2 is attached to the sponge pad 31, the glass plate A2 can be blocked by the sponge pad 31 to avoid collision between the glass plate A2 and the surface of the gun body 1, thereby preventing damage to the glass plate A2. The baffle 4 is pushed into the sliding groove of the mounting frame 3. In this process, the cotton strip 42 on the baffle 4 can wipe the surface dust of the glass plate A2, and after wiping is completed, the baffle 4 is used to shield and protect the glass plate A2. When the subsequent glass plate B21 has dust attached thereto, the baffle 4 shielding the glass plate A2 can be removed from the mounting frame 3. Then, the glass plate A2 is manually rotated to be parallel to the glass plate B21. Then, the clean glass plate A2 is pushed into the scanning port 11. Finally, the cotton strip 42 on the limiting frame 41 is replaced periodically.
[0031] The working principle of the handheld scanning gun provided by the utility model is as follows:
[0032] In the normal state, the glass plate B21 is located in the mounting frame 3 and is shielded by the baffle 4. At this time, the scanning port 11 is shielded by the glass plate A2.
[0033] When using the scanning gun, the data line is connected with the computer, the handheld handle 14 is held, and the gun body 1 is controlled through the control button. Then, the scanning port 11 is aligned with the goods code, and the goods information can be scanned through the scanning port 11 and recorded in the computer.
[0034] When the surface of the glass plate A2 has a lot of dust attached thereto, the baffle 4 shielding the glass plate B21 is removed. Then, the glass plate B21 is manually rotated so that the limiting plate 23 is clamped into the limiting groove 24, and the glass plate B21 is rotated to be parallel to the glass plate A2. The maximum rotation angle of the glass plate A2 and the glass plate B21 can be limited through cooperation between the limiting plate 23 and the limiting groove 24. In the process of rotating the glass plate A2 and the glass plate B21, the torsional spring 22 is compressed and starts to tighten. Then, the glass plate B21 is pushed into the scanning port 11 through the limiting port 12. At this time, the scanning port 11 is shielded by the clean glass plate B21, and after the glass plate A2 is pushed out of the scanning port 11, the torsional spring 22 starts to rebound and drives the glass plate A2 to rotate towards the gun body 1 until the glass plate A2 is attached to the sponge pad 31 on the gun body 1.
[0035] After the glass plate A2 is attached to the sponge pad 31, the glass plate A2 can be blocked by the sponge pad 31 to avoid collision between the glass plate A2 and the surface of the gun body 1, thereby preventing damage to the glass plate A2. The baffle 4 is pushed into the sliding groove of the mounting frame 3. In this process, the cotton strip 42 on the baffle 4 can wipe the surface dust of the glass plate A2, and after wiping is completed, the baffle 4 is used to shield and protect the glass plate A2. Finally, the cotton strip 42 on the limiting frame 41 is replaced periodically.
