The two sides of the inner wall of the U-shaped frame 202 are symmetrically provided with limit slots. The two sides of the strip lifting block 203 are symmetrically fixedly connected with the limit sliders 208. The outer walls of the two limit sliders 208 are slidably sleeved with the inner cavity of the limit slot corresponding to the position. The limit slot and the limit slider 208 are used to ensure that the strip lifting block 203 can move smoothly in the vertical direction. The back of the strip lifting block 203 is provided with a connecting block 204, and the connecting block 204 is fixedly connected to the back of the strip lifting block 203.

[0024] Working principle of this utility model:

[0025] When assembling the three-way gear set 1 into the three-way valve motor, first install the double gear 102 located at the bottom, adjust the distance between the circular plate 205 and the double gear 102 according to the installation height of the double gear 102, and rotate the threaded rod 206 counterclockwise through the force ball 210. The threaded rod 206 rotating counterclockwise in the T-shaped hole will drive the locking block 207 to disengage from the locking hole. When the locking block 207 is completely out of the locking hole, the bar lifting block 203 is driven to move in the vertical direction through the force ball 210. When it is determined that the distance between the circular plate 205 and the double gear 102 meets the installation height of the double gear 102, the threaded rod 206 is rotated clockwise through the force ball 210. The threaded rod 206 rotating clockwise in the T-shaped hole will drive the locking block 207 to disengage from the locking hole. Block 207 enters the locking hole. When the locking block 207 enters the locking hole to complete the positioning of the bar lifting block 203, the connecting block 204 and the circular strap 205, the double gear 102 is sleeved on the rotating shaft 101 until the bottom of the circular strap 205 is tightly fitted with the top of the rotating shaft 101. Finally, glue is dripped into the gap between the double gear 102 and the rotating shaft 101. When the two double gears 102 located at the top are operated according to the above steps and the glue is solidified, the assembly of the three-way gear set 1 is completed. When installing the three-way gear set 1, there is no need to wait until the glue at the lower double gear 102 is solidified before installing the upper double gear 102, which shortens the installation time of the three-way gear set 1 and improves the installation efficiency of the polyester three-way gear.
