The utility model relates to a compact type tensioning mechanism. The fixed seat is fixed on the rack around the tensioned transmission belt or transmission chain; the large end of the tensioning arm and the disc-shaped tensioning shell are coaxially arranged and connected through a fixing threaded sleeve, a torsion spring containing cavity is formed between the large end of the tensioning arm and the disc-shaped tensioning shell, the tensioning torsion spring is arranged in the torsion spring containing cavity, and a torsion arm at one end of the tensioning torsion spring is connected with a clamping spring groove formed in the disc-shaped tensioning shell in an inserted mode. The torsion arm at the other end is connected with a clamp spring hole formed in the large end of the tensioning arm in an inserting manner, so that the disc-shaped tensioning shell is connected with the large end of the tensioning arm in a relatively rotating manner; a screw is connected to the center of the fixed seat and the center
