[0028] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it is worth explaining in detail that the limit assembly 5 includes a plurality of symmetrically distributed elastic sheets 51 fixed to the side wall of one side of the top cover 4, and a plurality of symmetrically distributed brackets 52 fixed to the outer side wall of the shell 1, the elastic sheet 51 is located inside the bracket 52, and a limit groove 53 is provided on the side wall of one side of the bracket 52, and one side of the elastic sheet 51 is engaged with the limit groove 53, and a connecting plate 54 is fixed between every two adjacent elastic sheets 51. Through the setting of the limit assembly 5, the effect of tightly limiting the top cover 4 is achieved, which not only has a better limiting effect after the installation of the top cover 4, but also facilitates the disassembly and release of the limit of the top cover 4. The device realizes the installation limit work of the top cover 4 at a lower cost, has a simple structure but good reliability, is easier to operate for the staff, and effectively saves the complicated unlocking and limiting work processes.

[0029] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, it is worth specifically explaining that the protection assembly 7 includes a protection cover 71 provided on the top side wall of the top cover 4, the protection cover 71 is rotatably connected to the top cover 4 through two symmetrically distributed hinges 72, the control switch 6 is located directly below the protection cover 71, a mounting seat 73 is fixed to the top side wall of the top cover 4, one side wall of the mounting seat 73 slides through a limiting rod 74, one end of the limiting rod 74 is fixed with a pull ring 75, the outer surface of the limiting rod 74 is sleeved with a spring 76, one end of the spring 76 is fixed to the side wall of one side of the mounting seat 73, and the other end of the spring 76 is fixed to the side wall of one side of the mounting seat 73. The end is fixed to the side wall of one side of the pull ring 75, and a limiting hole 77 is provided on the side wall of one side of the protective cover 71. The limiting rod 74 is adapted to the limiting hole 77. Through the setting of the protection component 7, it can effectively avoid the situation of accidentally touching the control switch 6, thereby effectively preventing the loss caused by accidental touching, and can also form a good protection effect for the control switch 6, further improve the service life of the control switch 6, and can also realize the automatic limiting function when the flip protective cover 71 contacts the top cover 4, which is highly practical and has high structural flexibility.

[0030] This solution has the following working process: when the device needs to be used, the pull ring 75 is pulled to make the limit rod 74 move synchronously. At this time, the spring 76 is in a stretched state until the limit rod 74 is separated from the limit hole 77, thereby releasing the limiting effect on the protective top cover 4, and the handle 8 can be pulled to flip the protective top cover 4, and the control switch 6 can be operated accordingly.

[0031] According to the above working process, it can be known that: through the setting of the limit component 5, the top cover 4 can be tightly limited.

The device can achieve the installation limit work of the top cover 4 at a lower cost. The structure is simple but the reliability is good. It is easier to operate for the staff, and the complicated unlocking and limiting work process is effectively saved. Through the setting of the protection component 7, it can effectively avoid the situation of accidentally touching the control switch 6, thereby effectively preventing the loss caused by accidental touching.

[0035] Further as Figure 3 As shown, it is worth explaining in detail that a loading plate a9 is fixed on the outside of the shell 1, and two symmetrically distributed loading plates b10 are fixed on the outer side wall of the shell 1.

Through the arrangement of the rubber limit columns 12 and the rubber sleeves 13, not only can the mounting plate 2 be effectively supported and positioned, but the rubber limit columns 12 and the rubber sleeves 13 themselves have a certain soft effect, thereby achieving the purpose of shock absorbing for the mounting plate 2 and providing protection for the control structure.
