[0026] Working principle: insert the crystal head 25 into the cavity 2, the top of the crystal head 25 contacts the gear bar 3 and drives the gear bar 3 to move upwards, the gear bar 3 drives the gear 4 to rotate during the movement, and the gear 4 rotates to drive the winding group 5 rotates, and the winding group 5 rotates to drive the winding rope sleeve 6 to rotate through the connecting wire, the winding rope sleeve 6 rotates and pulls the sliding block 7, and the sliding block 7 is pulled by the connecting rod 8 to drive the fixed plate 9 to move towards the direction of the cavity 2, and the fixed The movement of the plate 9 drives the stop block 14 to move towards the cavity 2, so that the stop block 14 fixes the crystal head 25, and at the same time, the push block 15 is driven by the force of the crystal head 25 to drive the connecting rod 16 to rotate, thereby making the contact 17 contact , contact 17 makes the driving end of rotating pin 11 energized, rotating pin 11 begins to rotate to drive rotating rod 10 to rotate, rotating rod 10 rotates to drive speed limiting block 12 to move to the direction of winding rope cover 6, so that winding rope covering 6 stops rotating, Prevent continuing to increase the fixing strength of the crystal head 25 and cause the crystal head 25 to be damaged, turn on the power supply 19, the power supply 19 makes the guide rod 20 energized, the drive guide rod 20 rotates, the guide rod 20 rotates and rubs with the rubber block 21, in the electric field Under the action, the negative charge moves to the electrified guide rod 20, so that the two ends of the electrified guide rod 20 have different charges, and then an electrostatic field is generated on the surface of the electrified guide rod 20, and the dust is adsorbed under the action of static electricity. At this time, the motor is turned on , the motor drives the transmission rod connected to the transmission to rotate, and the transmission rod drives the negative pressure fan 24 to rotate, and the negative pressure fan 24 rotates to absorb the dust in the electrostatic field, so that the dust is adsorbed into the inside of the collection chamber 22, preventing the dust from accumulating and causing the heat dissipation of the exchanger equipment reduction in effect.
[0027] To sum up, the connection cable is stable and prevents poor heat dissipation. By inserting the crystal head 25 into the cavity 2, the top of the crystal head 25 contacts the rack bar 3 and drives the rack bar 3 to move upward. The rack bar 3 In the process of moving, the gear 4 is driven to rotate, the rotation of the gear 4 drives the winding group 5 to rotate, the winding group 5 rotates through the connecting wire to drive the winding rope sleeve 6 to rotate, the winding rope sleeve 6 rotates and pulls the sliding block 7, and the sliding block 7 is pulled through The connecting rod 8 drives the fixed plate 9 to move towards the direction of the cavity 2, and the movement of the fixed plate 9 drives the limit block 14 to move towards the cavity 2, so that the limit block 14 fixes the crystal head 25, and the push block 15 is received by the crystal head at the same time. The active force of 25 drives the connecting rod 16 to rotate, and then makes the contact 17 contact, and the contact of the contact 17 makes the driving end of the rotating pin 11 energized, and the rotating pin 11 starts to rotate to drive the rotating rod 10 to rotate, and the rotating rod 10 rotates to drive the speed limit block 12 Move to the winding rope cover 6 direction, make the winding rope cover 6 stop rotating, prevent from continuing to increase the fixing dynamics to the crystal head 25 and cause the crystal head 25 to be damaged.
[0028]Moreover, the connecting network cable is stable and prevents poor heat dissipation of the switch. By turning on the power supply 19, the power supply 19 energizes the guide rod 20, drives the guide rod 20 to rotate, and the guide rod 20 rotates and rubs against the rubber block 21. The lower negative charge moves to the conductive rod 20, so that the two ends of the conductive rod 20 have different charges, and then an electrostatic field is generated on the surface of the conductive rod 20, and the dust is adsorbed under the action of static electricity. At this time, the motor is turned on. The motor drives the transmission rod connected to the transmission to rotate, and the transmission rod drives the negative pressure fan 24 to rotate, and the negative pressure fan 24 rotates to absorb the dust in the electrostatic field, so that the dust is adsorbed into the interior of the collection chamber 22, preventing the dust from accumulating and causing the heat dissipation effect of the exchanger equipment decrease.
