The PLC frequency converter body 3 is placed on the two second mounting plates 2. Between them, the second mounting plate 2 provides limited support to the PLC frequency converter body 3. There are bumps 4 fixed on both sides of the PLC frequency converter body 3. The two first mounting plates 1 are provided with threaded rods 5 on one side. Two threaded rods 5 are threadedly connected to the bumps 4 respectively. The threaded force generated between the rotation of the threaded rods 5 and the bumps 4 drives the PLC frequency converter body 3 to gradually move toward the first mounting plate 1 to fit the first mounting plate 1, and where The outer surface of a threaded rod 5 is fixed with a driving gear 7. The outer surface of the driving gear 7 is meshed with a driven gear 8. A rotating shaft 9 is fixed in the middle of the driven gear 8. The rotating shaft 9 rotates, so that the driven gear 8 rotates, and the driven gear 8 rotates. The meshing force generated between the rotation of gear 8 and the driving gear 7 drives the rotation of the driving gear 7, and then one of the threaded rods 5 rotates;

Please refer to Figure 4. One end of the rotating shaft 9 extends to the outside of the first mounting plate 1 and is fixedly connected with a knob 10. Rotating the knob 10 drives the rotating shaft 9 to rotate, which is convenient for driving the rotating shaft 9 to rotate;

Please refer to Figure 3-4. One end of the threaded rod 5 extends to the inside of the first mounting plate 1 and the fixed sleeve is equipped with a transmission assembly 6. The transmission assembly 6 allows the two threaded rods 5 to rotate simultaneously. The transmission assembly 6 includes fixed sleeves respectively installed on both sides. There is a driving pulley 61 and a driven pulley 62 on the outer surface of the threaded rod 5. The outer surfaces of the driving pulley 61 and the driven pulley 62 are connected with a belt 63. The rotation of the driving pulley 61 drives the belt 63 to drive, and the belt 63 drives the driven pulley 62 to rotate. , and then the two threaded rods 5 rotate simultaneously;
