The instrument body 01 and hinge 36 used in this application are products that can be purchased directly on the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here.

[0025] Includes: instrument body 01, dustproof component 02 installed at the heat dissipation hole position of instrument body 01, and auxiliary component 03 set at the screen position of instrument body 01;

[0026] The dustproof component 02 includes a base frame 21. A screw 22 passes through the interior of both sides of the middle of the base frame 21, allowing the screw to be screwed into the instrument body 01 to fix its position. Springs 23 are installed inside the four corners of the base frame 21, providing elasticity to ensure the dust filter 24 is tightly fitted against the limiting plate 25, facilitating the limiting of the dust filter 24. The outer surface of the base frame 21 is fitted with the dust filter 24, with the upper and lower outer surfaces of the dust filter 24 abutting against the limiting plate 25. The limiting plate 25 can rotate around the dust filter 24 to limit its position. A protruding rod 26 passes through one end of the limiting plate 25, and a fixing block 27 is fixedly installed at one end of the protruding rod 26.

[0027] Furthermore, the auxiliary component 03 includes a fixing rod 31, with a second screw 32 passing through one end of the fixing rod 31. The second screw 32 can be screwed into the instrument body 01 through the fixing rod 31 to fix the position of the fixing rod 31. A shaft 33 is fixedly connected to the inner side of the end of the fixing rod 31 away from the second screw 32. A first protective plate 34 is connected to the outer wall of the shaft 33. After the first protective plate 34 is rotated downward around the shaft 33, the end of the first protective plate 34 away from the shaft 33 rests against the lower surface of the instrument body 01. The second protective plate 35 is rotated via a hinge 36. The movement causes the second protective plate 35, the instrument body 01, and the desktop to form a triangular support, supporting the instrument body 01. The second protective plate 35 is set on the side of the first protective plate 34 away from the shaft 33. The second protective plate 35 is connected to the first protective plate 34 through a hinge 36.

One end of spring 23 is fixedly connected to the bottom frame 21 to ensure the firmness of the position of spring 23. Spring 23 provides elasticity so that dust filter 24 is tightly attached to limit plate 25, which facilitates the limiting of dust filter 24.

[0029] Furthermore, when the dust filter 24 is pressed against the surface of the bottom frame 21, the spring 23 is in a compressed state. The spring 23 provides elasticity, which makes the dust filter 24 press against the limiting plate 25, so as to limit the dust filter 24.

[0030] Furthermore, the limiting plate 25 is rotatably connected to the protruding rod 26, and the limiting plate 25 can rotate around the limiting plate 25 to the outer surface of the dust filter 24 to limit the dust filter 24. The fixing block 27 is fixedly connected to the instrument body 01 to ensure the firmness of the fixing block 27 position.

[0031] Furthermore, the second screw 32 is threadedly connected to the instrument body 01. The second screw 32 can be passed through the fixing rod 31 and screwed into the instrument body 01 to fix the position of the fixing rod 31. The first protective plate 34 is rotatably connected to the shaft 33. The first protective plate 34 can be rotated around the shaft 33 to facilitate position adjustment of the first protective plate 34.

[0032] Furthermore, the second protective plate 35 is rotatably connected to the first protective plate 34 via a hinge 36. After the first protective plate 34 is rotated downward around the shaft 33, the end of the first protective plate 34 away from the shaft 33 rests against the lower surface of the instrument body 01. The second protective plate 35 rotates via the hinge 36, so that the second protective plate 35, the instrument body 01, and the table form a triangular support to support the instrument body 01. The instrument body 01 has a slot corresponding to the size of the retaining ball 37, which can be inserted into the slot of the instrument body 01. The first protective plate 34 and the second protective plate 35 are located on the screen surface of the instrument body 01, which can protect the screen of the instrument body 01.

[0033] Working Principle: In use, first place the base frame 21 in the designated position, then screw the first screw 22 through the base frame 21 and into the instrument body 01. Press the dust filter 24 onto the outer surface of the base frame 21. Rotate the limiting plate 25 around the protruding rod 26 to the outer surface of the dust filter 24 to limit its position. During use, the first protective plate 34 can be rotated downwards around the shaft 33, so that the end of the first protective plate 34 away from the shaft 33 rests against the lower surface of the instrument body 01. The second protective plate 35 rotates via the hinge 36, forming a triangular support with the second protective plate 35, the instrument body 01, and the tabletop, thus supporting the instrument body 01. This is the complete working principle of this utility model.
