[0027] This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1-4 The dehumidification component 5 includes a fixed frame 51 fixedly installed at the middle part on the top of the controller body 3 and a sealing plug 52 attached to the upper part of the inner cavity of the fixed frame 51. The fixed frame 51 is communicated with the inner cavity of the controller body 3. Fixing rods 53 are respectively fixedly installed at the bottom of the sealing plug 52 near the left and right sides. The lower ends of the fixing rods 53 are jointly fixedly installed with a net plate 54. The outer side of the net plate 54 is attached to the inner wall of the inner cavity of the fixed frame 51. And a desiccant 55 is attached to the middle part of the top of the net plate 54. Flat plates 56 are respectively fixedly installed at the top of the opposite sides of the fixed frame 51.

And clamping rods 59 are respectively slidably penetrated and installed on the clamping plates 58. The opposite ends of the clamping rods 59 are respectively fixedly installed on the adjacent slide plates 57, which plays a role in dehumidifying the humid air in the controller body 3, and can also replace the desiccant 55 regularly to avoid poor dehumidification effect after long-term use.

[0028] A handle 521 is fixedly installed at the middle of the top of the sealing plug 52, which is conducive to driving the sealing plug 52 to move upward through the handle 521.

[0029] Side plates 571 are respectively arranged on the opposite sides of the sliding plate 57, and the bottoms of the side plates 571 are respectively fixedly installed on the adjacent flat plates 56. Threaded rods 572 are respectively installed through the side plates 571 in a penetrating manner. The opposite ends of the threaded rods 572 are respectively movably installed on the adjacent sliding plates 57, and the opposite ends of the threaded rods 572 are respectively fixedly installed with hand wheels 573, which is conducive to the development of the disassembly work.

[0030] In this embodiment: The setting of the desiccant 55 plays a role in dehumidifying and drying the humid air in the controller body 3, and it can also be disassembled and replaced regularly. By rotating the hand wheels 573 on both sides, when the hand wheels 573 rotate, they will drive the adjacent threaded rods 572 to rotate. When the threaded rods 572 rotate, they will drive the adjacent sliding plates 57 to move in opposite directions. When the sliding plates 57 move in opposite directions, they will drive the adjacent clamping rods 59 to move in opposite directions. When the clamping rods 59 move in opposite directions, they will move away from the adjacent clamping plates 58. At this time, the clamping and fixing of the sealing plug 52 can be released. Then, pulling up the handle 521 can drive the sealing plug 52 to move upward. When the sealing plug 52 moves upward, it will drive the desiccant 55 to move upward to the outside of the fixed frame 51 through the fixing rod 53 and the mesh plate 54, which is conducive to replacing the desiccant 55. After the replacement is completed, the reverse operation can be performed to restore the sealing plug 52.

[0031] Working principle: When in use, the controller body 3 can be placed on the bearing plate 2. The positioning block 31 is provided to guide and position the controller body 3 during placement. After placement, the servo motor 41 can be operated. When the servo motor 41 operates, it drives the driving bevel gear 42 to rotate. When the driving bevel gear 42 rotates, it drives the driven bevel gears 43 on both sides to rotate. When the driven bevel gears 43 rotate, they drive the adjacent worm gears 44 to rotate. When the worm gears 44 rotate, they drive the adjacent worm wheels 45 to rotate. When the worm wheels 45 rotate, they drive the cam 46 to rotate through the adjacent movable rod. When the cam 46 rotates to contact the push plate 47, it drives the push plate 47 to move relatively synchronously. When the push plate 47 moves relatively, it drives the moving rods 48 on both sides to move relatively through the guide rod 472, and at the same time, it also squeezes the adjacent return spring 473. When the moving rods 48 move relatively, they drive the adjacent positioning plates 49 to move relatively, so as to realize the clamping and positioning of the controller body 3. In addition, the desiccant 55 is provided to dehumidify and dry the humid air in the controller body 3, and it can also be disassembled and replaced regularly. By rotating the handwheels 573 on both sides, when the handwheels 573 rotate, they drive the adjacent threaded rods 572 to rotate. When the threaded rods 572 rotate, they drive the adjacent sliding plates 57 to move in opposite directions. When the sliding plates 57 move in opposite directions, they drive the adjacent clamping rods 59 to move in opposite directions. When the clamping rods 59 move in opposite directions, they move away from the adjacent clamping plates 58. At this time, the clamping and fixing of the sealing plug 52 can be released. Then, pulling up the handle 521 can drive the sealing plug 52 to move upward. When the sealing plug 52 moves upward, it drives the desiccant 55 to move upward to the outside of the fixing frame 51 through the fixing rod 53 and the mesh plate 54, which is beneficial to replacing the desiccant 55. After replacement, reverse operation can restore the sealing plug 52 to its original state.
