A tool for accurately controlling the installation angle and height of a pipe joint comprises a fixing base and an installation positioning plate, the fixing base is fixed to a vehicle accessory, thetop of the fixing base is fixedly connected with one end of the installation positioning plate, a positioning protruding block is arranged at the other end of the installation positioning plate, and the top face of the positioning protruding block is a height attaching face. The side face of the positioning protruding block is an angle attaching face, and a thrust line for the pipe joint is formedat the connected position of the top face and the side face. During use, an initial screwing-in angle is calculated firstly, then the fixing base is fixed to the vehicle accessory, and the pipe jointstarts to be screwed from the initial screwing-in angle till the intersecting line of the center face of the pipe joint and the bottom of the pipe joint coincides with the thrust line, and finally, apipe joint locking nut is s
