The present invention provides a massager comprising: a control mechanism including a housing, the housing being a hard shell having a wearing groove adapted to fit the user's patella, the opening of the wearing groove of the housing abutting the periphery of the patella; and a fixing mechanism connected to the housing and wrapped around the housing to be fixed to the user's knee region so that the user's patella is accommodated in the wearing groove, the fixing mechanism being provided with a massage airbag corresponding to the knee region. Because the opening of the wearing groove of the housing abuts the periphery of the patella and the housing being a hard shell, when the massage airbag inflates, the fixing mechanism inevitably applies a tensile force to both ends of the housing, and this tensile force is transmitted to the area around the patella. The housing does not directly squeeze the patella, nor does it affect the user's sitting or walking, thereby preventing improper squeezing of the patella and the resulting poor massage effect.
