[0033] When in use, the barcode scanner is connected to the barcode scanner device via the connecting line 1505, and the protective shell 3 at the handle 1 is held to scan the barcode. When the handle 1 of the barcode scanner falls or collides, that is, the protective shell 3 is collided, the two U-shaped plates 4 arranged between the protective shell 3 and the handle 1 make the slide bar 8 displace inside the sleeve 7, that is, the sleeve 7 and the support block 10 move relative to each other in the vertical direction, and the limit ring 902 arranged at the bottom of the slide bar 8 can make the spring 901 The position of the barcode scanner 1 is deformed, and the position limiting plate 903 and the second spring 904 are combined to make the second spring 904 deformed, so as to provide a buffer and protection for the handle 1. At the same time, the relative movement of the sleeve 7 can make the support block 10 displace in the vertical direction. The rotation block 15, the second rotation block 11 and the spring telescopic rod 16 are combined to make the spring telescopic rod 16 deformed to a certain extent, so that it swings. The combination of the shock absorber 17 can provide a buffer and anti-fall effect for the handle 1 of the barcode scanner, thereby improving the anti-fall performance of the barcode scanner itself.

[0034] When the scanning terminal 2 of the barcode scanning gun collides or falls, the multiple anti-collision rings 13 and the multiple L-shaped anti-collision rods 14 are set to prevent the scanning terminal 2 from falling. At the same time, the arc plate 1501 collides, causing the multiple L-shaped anti-collision rods 14 to be displaced to a certain extent inside the anti-collision ring 13. Combined with the setting of the spring telescopic rod 1503 and the shock absorber 1502, it is convenient to buffer and prevent the scanning terminal 2 from falling again, thereby ensuring the normal use of the barcode scanning gun and having good anti-fall performance.
