[0030] In this embodiment, when using the three-way connector body 3, it can be positioned and installed according to the usage position. Pulling the limit slider 235 compresses the limit spring 234, and the positioning tooth 232 separates from the positioning gear 231. At this time, the positioning gear 231 is no longer blocked.

[0031] The operator can rotate the drive shaft 24 to drive the bevel gear 28 to rotate. The bevel gear 27 connected to both sides of the bevel gear 28 rotates and drives the threaded rod 26 to rotate. At this time, the movable frame 22 on the surface of the threaded rod 26 moves inside the guide frame 25 and pushes the positioning frame 21 away from each other. The positioning frame 21 abuts against the bracket or the two ends of the well to support the body 3 of the tee. The positioning frame 21 is set with a U-shaped structure so that it can be stuck on the surface of the bracket, improving the applicability of the equipment, ensuring the stability of the working of the body 3 of the tee, and improving the installation quality.

[0032] After the adjustment is completed, release the limit slider 235 to reset the limit spring 234. At this time, the positioning tooth 232 is re-inserted into the positioning gear 231 to limit it, preventing the drive shaft 24 from rotating and loosening, and ensuring the positioning strength of the three-way body 3.
