No wiring is required inside the control unit, the wiring is simple and the integration is high. However, when the above equipment is in use, when the wiring is completed, the wires may become tangled or mixed together if they are not sorted out in time, which is not convenient for the second inspection and maintenance. Therefore, we propose an intelligent positive pressure controller. Utility Model Content

[0027] In the above structure, the outer wall of one end of the screw rod 602 is fixedly installed with the power output shaft of the motor 9. When the motor 9 starts working, it can drive the screw rod 602 to start rotating. The threads at both ends of the screw rod 602 through the ring 604 are reverse threads to each other, so that the screw rod 602 can drive the two groups of moving blocks 603 to rotate in the same direction, so that the two groups of moving blocks 603 can clamp the electronic component 7. When a problem occurs with the electronic component 7, the motor 9 drives the screw rod 602 to start rotating. At this time, the two groups of moving blocks 603 start rotating, so that the electronic component 7 can be removed and replaced.
[0028] In a preferred embodiment, the outer wall of one end of the support frame 10 away from the motor 9 is fixedly mounted on the inner wall of the housing 1 , and the motor 9 is electrically connected to the main control module 4 .

At this time, the fixed component 8 can be moved so that the fixed component 8 can be moved to a suitable position. The push rod 807 is manually lowered to make the square plate 804 rest against the outer wall of the rectangular block 5. At this time, the elastic member 805 is reset to avoid displacement of the fixed component 8. By clamping the cleaned wires to the inner wall of the clamping member 802 and the clamping of the clamping member 802, it can effectively prevent the wires from being tangled due to too many wires.

[0033] In the above structure, the outer wall of the round rod 803 is slidably connected to the inner wall of the rectangular groove one. When the round rod 803 slides in the rectangular groove one, the round rod 803 is fixed to the slider 801, so that the clamping member 802 can drive the slider 801 to move, so that the position of the fixed component 8 can be adjusted to adapt to wires of different lengths. The round rod 803 is slidably connected to the inner wall of the rectangular groove two.

When the motor 9 starts working, it can drive the screw rod 602 to start rotating. The threads at both ends of the screw rod 602 through the ring 604 are reverse threads to each other, so that the screw rod 602 can drive the two groups of moving blocks 603 to rotate in the same direction, so that the two groups of moving blocks 603 can clamp the electronic component 7. When there is a problem with the electronic component 7, the motor 9 drives the screw rod 602 to start rotating. At this time, the two groups of moving blocks 603 start to rotate, so that the electronic component 7 can be clamped. The sub-component 7 is removed and the electronic component 7 is replaced. After the replaced electronic component 7 is clamped again by the clamping assembly 6, the wires at the bottom of the electronic component 7 are clamped by the fixing assembly 8, and the push rod 807 is pulled so that the push rod 807 can drive the square plate 804 to rise on the outer wall of the round rod 803, so that the square plate 804 can compress the elastic member 805. At this time, the fixing assembly 8 can be moved so that the fixing assembly 8 can be moved to a suitable position, and the push rod 807 is manually lowered so that the square plate 804 is against the outer wall of the rectangular block 5. At this time, the elastic member 805 is reset to avoid displacement of the fixing assembly 8, and the wires after cleaning are clamped to the inner wall of the clamping member 802 and the clamping of the clamping member 802 can effectively prevent the wires from being tangled due to too many wires.
