Abstract: The invention discloses a quick tee joint component and a drilling jig component specially for drilling. For installation of a quick tee joint, a drilling jig for quick tee joint is firstly installed on a pipe where a branch pipe is to be added. A bushing of the drilling jig is in threaded connection with the drilling jig, to achieve convenient replacement, and is made of a high-hardness metal material. Under the limiting action of the bushing, the position of a reamer is ensured not to deviate during the reaming process, thereby ensuring the reaming quality. The requirement for different sizes of holes drilled by the drilling jig can be met by simply changing the size of the bushing of the drilling jig. Once reaming is done, fastening bolts are unscrewed so as to remove the drilling jig and a quick tee joint body is installed. A lengthening part of the quick tee joint body guarantees the installation position accuracy of the quick tee joint.
