[0029] The limiting structure 2 includes a fixing seat 21 and a limiting block 23, and the lower end surface of the fixing seat 21 is fixedly connected to a corner of the lower end surface of the main cabinet 15. The limiting structure 2 also includes a threaded rod 22, and the threaded rod 22 is threadedly connected to the inside of the fixing seat 21, and one end of the threaded rod 22 is fixedly connected to the limiting block 23.

[0030] Embodiment 2 like Figure 7 and Fig.10 As shown, the present embodiment further proposes: an adjustment structure 5, the adjustment structure 5 is provided with multiple groups, and the adjustment structure 5 includes a lower sliding seat 51 and a limiting column 56, and the surface inside the lower sliding seat 51 is in contact with the surface of the lower end of the adjustment seat 17, the adjustment structure 5 also includes a first connecting seat 52, and the first connecting seat 52 is provided with two groups, and the two groups of first connecting seats 52 are respectively fixedly connected to the surfaces on both sides of the upper end of the lower sliding seat 51, and the two groups of first connecting seats 52 are inserted with balls 53 inside, and the surfaces of the upper ends of the two groups of first connecting seats 52 are fixedly connected with the upper sliding seats 54, and the sizes of the two groups of balls 53 are consistent with the inner surface of one end of the adjustment seat 17. The sizes of the parts are adapted, and the two groups of balls 53 can slide inside the two groups of first connecting seats 52. The outer surfaces of the two groups of balls 53 fit the inner surface of one end of the adjusting seat 17. Since the contact area between the two groups of balls 53 and the inner surface of one end of the adjusting seat 17 is small, the resistance of the adjusting structure 5 when sliding on the outer surface of one end of the adjusting seat 17 can be reduced, so that the position of the adjusting structure 5 can be adjusted more easily, and through the arrangement of the lower sliding seat 51 and the upper sliding seat 54, the shaking of the adjusting structure 5 when moving on the outer surface of one end of the adjusting seat 17 can be avoided, thereby improving the stability of the adjusting structure 5 when in use.

[0031] The surface of the lower end of the lower sliding seat 51 is fixedly connected with a second connecting seat 55, and a limiting column 56 is inserted into the interior of one end of the second connecting seat 55, and one end of the limiting column 56 is fixedly connected to a connecting rod 57, a spring 58 is sleeved on the outer surface of the connecting rod 57, and one end of the connecting rod 57 is fixedly connected to an adjusting block 59, and the surface of the other end of the limiting column 56 is against the lower surface of one end of the adjusting seat 17. Due to the elastic force of the spring 58 itself, the limiting column 56 and the adjusting seat 17 can be pressed tightly, which can increase the friction between the limiting column 56 and the adjusting seat 17, thereby preventing the adjusting structure 5 from moving on the outer surface of one end of the adjusting seat 17, fixing the position of the adjusting structure 5, and dialing The adjusting block 59 is rotated ninety degrees, and one end of the adjusting block 59 is pressed against the outer surface of one end of the second connecting seat 55, pulling the limiting column 56 and the connecting rod 57 to move inside the second connecting seat 55, and the spring 58 is pressed to contract, and the surface of the other end of the limiting column 56 is separated from the lower surface of one end of the adjusting seat 17, so that the adjusting structure 5 can move on the outer surface of one end of the adjusting seat 17, and the adjusting block 59 is rotated to reset it. The spring 58 can use its own elastic force to push the limiting column 56 and the connecting rod 57 to reset, so that the surface of the other end of the limiting column 56 is pressed against the lower surface of the other end of the adjusting seat 17, thereby preventing the adjusting structure 5 from moving.

[0032] The fixed structure 6 is provided with multiple groups, and the fixed structure 6 includes a connecting plate 61 and a fixing block 66, and one end of the connecting plate 61 is fixedly connected to the surface of one end of the lower sliding seat 51, and the fixed structure 6 also includes a protective plate 62, and the protective plate 62 is provided with two groups, and the surfaces on the opposite sides of the lower ends of the two groups of protective plates 62 are respectively fixedly connected to the surfaces on both sides of the connecting plate 61, and the two groups of protective plates 62 are provided with heat dissipation holes 63 inside, and the upper surface of the connecting plate 61 is provided with a monitoring module 64, and the surfaces on the opposite sides of the upper ends of the two groups of protective plates 62 are fixedly connected with a fixing plate 65. When the adjustment structure 5 is moved, the fixed structure 6 can be driven to move as a whole, and the other end of the connecting plate 61 is inserted into the inside of the other end of the adjustment seat 17. This design can improve the fixing structure. The surface of the two sets of heat dissipation holes 63 on the opposite side of the monitoring module 64 is attached to the surfaces on both sides of the monitoring module 64. This design can improve the stability of the monitoring module 64 and protect the monitoring module 64. The two sets of heat dissipation holes 63 can promote air circulation and increase the air exchange on the surfaces on both sides of the monitoring module 64, which is helpful to improve the internal temperature of the monitoring module 64 and improve the working efficiency of the monitoring module 64. Good ventilation and heat dissipation can extend the service life of the monitoring module 64 and reduce the failure rate of the monitoring module 64. The lower surface of the fixing plate 65 is attached to the upper surface of the monitoring module 64, so that the fixing plate 65 can prevent the monitoring module 64 from moving, further improving the stability of the monitoring module 64 when in use. A fixing block 66 is inserted into the interior of one end of the fixing plate 65, and the surface of one side of the lower end of the fixing block 66 is in contact with the surface of one end of the monitoring module 64. The size of the fixing block 66 is matched with the size of the interior of one end of the fixing plate 65, so that the fixing block 66 can move up and down inside one end of the fixing plate 65 without shaking and will not separate from the interior of the fixing plate 65. The lower end surface of the fixing block 66 is in contact with the surface of the lower end of the fixing plate 65 by its own gravity, and the surface of one side of the lower end of the fixing block 66 is in contact with the surface of one end of the monitoring module 64, which can prevent the monitoring module 64 from moving outward, thereby fixing the position of the monitoring module 64. Lifting the fixing block 66 upward can separate the surface of one side of the lower end of the fixing block 66 from the surface of one end of the monitoring module 64, and the monitoring module 64 can be pulled out at this time. This design allows the monitoring module 64 to be freely replaced according to usage, further improving the flexibility of the equipment when used.

[0033] Working principle: When the device is in use, the threaded rod 22 is rotated to drive the limit block 23 to move, so that the limit block 23 is disengaged from the inside of a group of fixing holes, and then the main cabinet 15 is pulled outward from the inside of the extended cabinet 11, and then the threaded rod 22 is rotated to drive the limit block 23 to move and insert it into the inside of another group of fixing holes, so that the position between the extended cabinet 11 and the main cabinet 15 is fixed. At this time, the space inside the extended cabinet 11 is expanded, increasing the usable space inside the device. At this time, additional functional modules can be installed inside the extended cabinet 11, and then the first protective door 14 is sleeved on the outer surface of the first connecting shaft 13, so that the first protective door 14 and the second protective door 110 can respectively protect the interior of the extended cabinet 11 and the main cabinet 15, and provide a power source for the cooling fan 3 through an external power supply, and start the cooling fan 3 to dissipate heat from the inside of the main structure 1; Then, the adjusting block 59 is toggled to drive the connecting rod 57 and the limiting column 56 to move and the spring 58 to contract, so that the surface of the other end of the limiting column 56 is separated from the lower surface of one end of the adjusting seat 17, and then the adjusting structure 5 is pulled to move on the outer surface of the adjusting seat 17 to move the fixed structure 6 to a suitable position, and then the adjusting block 59 is toggled to reset, and the spring 58 resets the connecting rod 57 and the limiting column 56 through its own elastic force, so that the surface of the other end of the limiting column 56 is again pressed against the lower surface of one end of the adjusting seat 17, thereby fixing the position of the adjusting structure 5 and the fixed structure 6; Pull the fixing block 66 upward so that the surface on one side of the lower end of the fixing block 66 is separated from the surface at one end of the monitoring module 64. At this time, the monitoring module 64 can be pulled out and replaced according to the usage. Then the replaced monitoring module 64 is pushed into the interior of the connecting plate 61. The surface at the other end of the monitoring module 64 pushes the fixing block 66 to move upward. When the upper surface of the monitoring module 64 is separated from the surface at the lower end of the fixing block 66, the fixing block 66 falls due to its own gravity, so that the surface on one side of the lower end of the fixing block 66 pushes against the surface at one end of the monitoring module 64, thereby fixing the position of the monitoring module 64. The above is the entire working principle of the present invention.
