[0023] The mounting bolt 13 and the bar code scanning PCB board body 7 cooperate with each other, and the bar code scanning PCB board body 7 is mounted at the rear end of the key bracket 9 through the mounting bolt 13 and the fixing hole 17;

[0024] Specifically, as shown in Figure 2 , Figure 3 , Figure 5 and Figure 6 , when installing the bar code scanning PCB board body 7, align the fixing holes 17 on the bar code scanning PCB board body 7 with the fixing holes 17 on the key bracket 9. After alignment, screw the mounting bolt 13 into the fixing hole 17 to install and fix the bar code scanning PCB board body 7. Using the mounting bolt 13 and the fixing hole 17 to install the bar code scanning PCB board body 7 does not require other parts for support, which can not only improve the installation efficiency, but also save costs. Directly installing the bar code scanning PCB board body 7 on the key bracket 9 can improve the applicability of the positioning posts 5 and reduce the space occupied by the installation of the bar code scanning PCB board body 7. The gasket 14 outside the mounting bolt 13 can prevent the mounting bolt 13 from accidentally disengaging from the inside of the fixing hole 17.

[0025] Control keys 3 are arranged at the edges on the left and right sides at the front end of the key bracket 9, a display screen 4 is installed inside the key bracket 9 and the front plate 2, positioning posts 5 are fixedly connected to both sides at the front end of the key bracket 9, guiding holes are formed on both sides inside the front plate 2, and the positioning posts 5 are embedded inside the guiding holes. The control keys 3 penetrate through both sides inside the front plate 2;
