[0024] in:

[0025] like Figure 2-3As shown, the upper shell 10 is a one-piece molded structure. A clearance part 11 is formed at the front of the upper shell 10 to avoid the scroll wheel 30. The clearance part 11 runs through the front of the upper shell 10 along the center line of the mouse and forms two symmetrically arranged pressing parts 12 on its left and right sides. Each pressing part 12 has a trigger part 13, a limit buckle 14 and a reinforcing part 15 extending toward the lower shell 20 on its inner wall. The two ends of each reinforcing part 15 are respectively connected to a trigger part 13 and a limit buckle 14. A U-shaped connecting buckle 16 is provided in the middle of the two pressing parts 12. The connecting buckle 16 is mounted below the end of the clearance part 11 and its two opposite side walls are respectively connected to a pressing part 12.

[0026] like Figure 3 As shown, in this embodiment, each reinforcing part 15 includes several ribs 1 disposed on and connected to the inner wall of a pressing part 12. Two ribs 1 are connected to the two ends of a limiting buckle 14, and the other two ribs 1 are connected to the two ends of a trigger part 13. Each limiting buckle 14 is a U-shaped structure, and a limiting plate 21 can be accommodated between its two opposite side walls. Its two side walls are arranged parallel to each other and extend to the inner wall of a pressing part 12. Each limiting plate 12 has a reinforcing plate 2 at its upper end. The upper shell 10 is provided with an upper guide part, which includes a first protrusion 17 and a... A plurality of second protrusions 18 are provided, and a first protrusion 17 is provided on the contour edge of the lower end of the upper shell 10 and extends along its contour. Each second protrusion 18 is provided on the inner wall of the rear part of the upper shell 10 and extends vertically toward the lower shell 20. A lower guide portion is provided on the lower shell 20, which includes a third protrusion 22 and a plurality of fourth protrusions 23. The third protrusion 22 is provided on the contour edge of the upper end of the lower shell 20 and is matched and provided on the inner side directly below the first protrusion 17. Each fourth protrusion 23 is vertically provided on the inner wall of the lower shell 10 and is adapted to a second protrusion 18.

[0027] like Figure 4 As shown, two horizontally arranged limiting plates 21 are provided on the inner wall of the side wall of the lower shell 20, and each limiting plate 21 is located directly below a limiting buckle 14.

[0028] like Figure 4 As shown, in this embodiment, a support portion is provided on the inner wall of the lower shell 20. The support portion includes several fifth protrusions 24 for supporting and fixing the rollers 30 and the circuit board 40. A battery cover 50 is detachably fixed on the outer wall of the lower shell 20. Several clearance slots 25 are provided on the side of the battery cover 50. Each clearance slot 25 penetrates the lower shell 20 and is located below an electronic component on the circuit board 40.

[0029] In this embodiment, both the lower shell 10 and the battery cover 50 are provided with one or more foot pads 60 at their bottom ends.

[0030] During assembly, first fix the circuit board 40, roller 30 and other components onto the fifth protrusion 24 of the lower shell 20, then fasten the upper shell 10, so that each second protrusion 18 on the upper shell 10 matches and engages with a fourth protrusion 23 on the lower shell 20. Then, put the two connecting buckles 16 on the upper shell 10 on the outside of the two limiting plates 21, and fasten the first protrusion 17 on the outer edge of the bottom contour of the upper shell 10 on the outside of the third protrusion 22 on the lower shell 20. At this time, the two trigger parts 13 on the upper shell 10 extend to the top of the two switching components on the circuit board 40. Finally, insert the battery into the lower shell 20 from the bottom end, and close the cover plate 60.

[0031] In this invention, both the upper shell 10 and the lower shell 20 are integrally molded plastic shells. They can be positioned by fastening with a first protrusion 17 and a third protrusion 23, several matching second protrusions 18 and fourth protrusions 23, and matching two limiting buckles 14 and limiting plates 21 located at their front, middle, and rear parts, making assembly convenient. By providing a clearance part 11 on the upper shell 10 and a connecting buckle 16 therebetween, the front part of the upper shell 10 can be transformed into left and right buttons that can move relatively within a certain range. Furthermore, by providing a trigger part 13 on each clearance part 11 that can extend above the switch on the circuit board 20, and by using limiting buckles 14 and limiting plates 21 on the upper and lower shells to limit the maximum travel of the buttons, the normal use of the left and right buttons can be ensured. The overall structure of the mouse is simple, and the manufacturing and assembly costs are relatively low.

[0032] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
