[0047] When the present invention is in use, by fixing the two housings 10 to the left and right ends of the energy-saving permanent magnet speed regulator body 9, and then snapping the four clamping seats 13 to the two housings 10 in sequence, the two housings 10 can compress the two sets of telescopic rods 222 equipped with the first connecting springs 14. When the clamping seats 13 are snapped into place, the telescopic rods 222 with elastic force can automatically extend and snap into the slots 100 of the two housings 10, which are used to snap and position the clamping seats 13. In this way, the four clamping seats 13 can preliminarily fix the housing 10 of the energy-saving permanent magnet speed regulator, and the two housings 10 are snapped to fix the heat sink 11, so that the heat sink 11 fits the permanent magnet speed regulator body. In order to quickly dissipate heat, the card plate 15 is then inserted into the card seat 13, so that the card seat 13 will drive the two U-shaped seats 16 to be carded onto the shell 10, which is conducive to further assembling the shell 10 of the energy-saving permanent magnet speed regulator. In this way, the card connection method can not only facilitate the loading and unloading of the permanent magnet speed regulator, but also save time and effort in operation, and can also conveniently disassemble the shell 10 to realize rapid maintenance of the energy-saving permanent magnet speed regulator, thereby improving the maintenance efficiency of the energy-saving permanent magnet speed regulator.

[0048] By placing the energy-saving permanent magnet speed regulator body 9 between the two positioning plates 7 and then rotating the first hand wheel 18, the first hand wheel 18 can drive the first double-headed screw 6 to rotate, so that the two positioning plates 7 on the first double-headed screw 6 can move toward each other, so that the energy-saving permanent magnet speed regulator body 9 can be installed on the bearings 8 of the two positioning plates 7, and then rotating the second hand wheel 32, the second hand wheel 32 can drive the second double-headed screw 30 to rotate, so that the two movable plates 33 on the second double-headed screw 30 can move toward each other, so that the first protective cover 34 and the second protective cover 35 can move to surround the energy-saving permanent magnet speed regulator body 9, increase the safety of the energy-saving permanent magnet speed regulator when in use, and avoid accidental contact by others. At the same time, the servo motor 39 can drive the fan shaft 38 to rotate and blow air continuously so that the heat generated by the energy-saving permanent magnet speed regulator can be quickly dissipated, and the lower inclined grooves 40 and the heat dissipation holes 41 on the first protective cover 34 and the second protective cover 35 can make the heat dissipation effect of the energy-saving permanent magnet speed regulator better and improve its heat dissipation effect;

[0049] By using the energy-saving permanent magnet speed regulator main body 9, a certain vibration force can be generated, and the vibration force can be transmitted to the top plate 3 at this time, so that the four gear rods 23 can be rotated and adjusted at the four racks 22 to buffer and weaken the vibration force. Subsequently, the first rubber seat 26 equipped with the second connecting spring 24 will also squeeze the second rubber seat 27 equipped with the third connecting spring 28, so that the elastic force of the connecting spring is utilized and the two rubber seats provide buffering protection for the entire permanent magnet speed regulator, and the damper 2 can also absorb the vibration force so that the vibration energy can be weakened, thereby improving the buffering effect of the energy-saving permanent magnet speed regulator and extending its service life. At the same time, the limit block 5 can be used to move up and down at the vertical plate 4, so that the energy-saving permanent magnet speed regulator main body 9 at the top plate 3 can smoothly and reliably buffer the vibration force, thereby achieving the effect of shock absorption.

[0050] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
