The piston and the elastic member are accommodated inside the accommodating cavity. One end of the elastic member faces the piston. The power adjusting assembly includes: an adjusting nut; a bevel gear; an adjusting shaft; and a power adjusting rod. The adjusting nut, the bevel gear, and the adjusting shaft are accommodated inside the accommodating cavity. One end of the adjusting nut faces an other end of the elastic member opposite to the piston. The bevel gear faces the other end of the adjusting nut opposite to the elastic member. One end of the adjusting shaft is inserted through the bevel gear and the adjusting nut. One end of the power adjusting rod is inserted through the first accommodating hole and leaning on the bevel gear. The other end of the power adjusting rod is extended outside the main body through the first accommodating hole. The end cap and the tail cap are formed to seal two opening ends of the accommodating cavity respectively. One end of the piston opposite to the elastic member faces the tail cap. The other end of the adjusting shaft faces the end cap. The floor closer is capable of adjusting power to close a door.</p> |
