The invention relates to a manufacturing apparatus of a prefabricated component reinforcing steel bar sleeve slurry anchor connection specimen having an assembly type structure. The manufacturing apparatus comprises vertical columns providing a support effect, cross beams providing a support effect, a plurality of special clampers providing a specimen fixation effect, a plurality of reinforcing steel bars for connecting the special clampers and the cross beams, and a plurality of bolts with a fastening nut, wherein sizes of clamping grooves for fixing the same specimen on the cross beams are the same, and the clamping grooves are positioned in the same vertical direction. The manufacturing apparatus has characteristics of simple structure, low manufacturing cost and strong versatility. With the manufacturing apparatus of the prefabricated component reinforcing steel bar sleeve slurry anchor connection specimen, the high quality reinforcing steel bar sleeve slurry anchor connection specimen can be manufactured, the specimen manufacturing speed can be improved, grouting material waste can be avoided, a lot of cost and times are saved, deviation on test detection results due to the non-raw material factor influence is reduced, and the test accuracy coefficient is improved.
