[0025] In this embodiment, a through hole 5 is opened on the front of the sheath 2. One end of the connecting rod 16 passes through the inner wall of the sheath 2 through the through hole 5 and extends to the front of the sheath 2, facilitating the movement of the dust-proof net main body 7 by driving the dust-proof frame 4 through the connecting rod 16, thereby facilitating the adjustment of the height of the dust-proof net main body 7. Embodiment

[0026] Based on Embodiment 1, a preferred embodiment of the external dust-proof net device provided by the present utility model is as follows Figures 1 to 4 As shown: The inner bottom wall and inner top wall of the dust-proof frame 4 are respectively fixedly connected with a lower spring 6 and an upper spring 15, and one end of the lower spring 6 and one end of the upper spring 15 are respectively fixedly connected with a lower clamping plate 13 and an upper clamping plate 12, and grooves 11 are formed at the top of the lower clamping plate 13 and the bottom of the upper clamping plate 12, which is convenient for installing and disassembling the dust-proof net main body 7, so as to facilitate the replacement of the dust-proof net main body 7 when the dust-proof net needs to be replaced.

[0027] In this embodiment, the shape and size of the groove 11 are both mutually matched with the shape and size of the dust-proof net main body 7, and the outer wall of the dust-proof net main body 7 is movably connected with the inner wall of the groove 11, which is convenient for connecting the dust-proof net main body 7 with the upper clamping plate 12 and the lower clamping plate 13.
