The invention discloses a twisted pipe and end plate installing and adjusting tool. The twisted pipe and end plate installing and adjusting tool comprises a fixing base, a fixed positioning base, a movable positioning base and a track. The fixed positioning base and the movable positioning base are used for positioning the relative position of an end plate and a twisted pipe. The fixed positioning base and the track are arranged at the upper portion of the fixing base. The fixed positioning base and the movable positioning base are located at the two ends of a guide rail correspondingly. The movable positioning base comprises a movable push base and a push rod, wherein the push rod is connected to the fixing base, the end portion of a telescopic rod of the push rod is connected to the movable push base, and the movable push base is arranged on the track. By means of the twisted pipe and end plate installing and adjusting tool, the end plate and the twisted pipe can be accurately positioned, and the situation that the heat collector unit installing precision does not meet the using requirement is avoided.
