The fixed rack has a through hole. The movable rack is movably attached to the fixed rack. The hitching bracket has a striding portion for being disposed on a side rack of the bed frame, and an extended portion extended from the striding portion and having a groove. The fastener is inserted through the through hole of the fixed rack and the groove of the hitching bracket for connecting the hitching bracket with the fixed rack. As a result, the user has no need to throw away the normal bed existing at home and buy a whole new electric bed, and can enjoy the lifting and lowering effect like the electric bed on the existing normal bed. ## Claims ### Claim 1 An electric bed frame, which is adapted for connection with a bed frame having a head portion, a foot portion and two side racks, two ends of each of the side racks being connected with the head portion and the foot portion respectively, the electric bed frame comprising: a fixed rack having a through hole; a movable rack movably attached to the fixed rack; a hitching bracket having a striding portion for being disposed on the side rack of the bed frame, and an extended portion extended from the striding portion and having a groove; and a fastener inserted through the through hole of the fixed rack and the groove of the hitching bracket for connecting the hitching bracket with the fixed rack. ### Claim 2 (depends on 1) The electric bed frame as claimed in claim 1, wherein the groove of the hitching bracket is elongated-shaped. ### Claim 3 (depends on 2) The electric bed frame as claimed in claim 2, wherein the groove is elongated in a direction perpendicular to another direction, in which the side racks of the bed frame are elongated. ### Claim 4 (depends on 1) The electric bed frame as claimed in claim 1, wherein the striding portion of the hitching bracket is reverse-U-shaped. ### Claim 5 (depends on 4) The electric bed frame as claimed in claim 4, wherein the striding portion of the hitching bracket has a top wall for being abutted on a top side of the side rack, an outer wall extended downwardly from an outer side of the top wall, and an inner wall extended downwardly from an inner side of the top wall for sandwiching the side rack between the outer wall and the inner wall. ### Claim 6 (depends on 5) The electric bed frame as claimed in claim 5, wherein the inner wall has a threaded hole for being screwed with a tightening member to enable an end of the tightening member to be abutted against the side rack of the bed frame. ### Claim 7 (depends on 6) The electric bed frame as claimed in claim 6, wherein the tightening member is provided at the end thereof with an abutting plate for being abutted against the side rack of the bed frame. ### Claim 8 (depends on 1) The electric bed frame as claimed in claim 1, wherein the through hole of the fixed rack is elongated-shaped. ### Claim 9 (depends on 8) The electric bed frame as claimed in claim 8, wherein the through hole is elongated in a direction perpendicular to another direction, in which the side racks of the bed frame are elongated. ### Claim 10 (depends on 1) The electric bed frame as claimed in claim 1, wherein the fastener has a screw bolt and a screw nut, which are screwed with each other. ### Claim 11 An electric bed frame, which is adapted for connection with a bed frame having a head portion, a foot portion and two side racks, two ends of each of the side racks being connected with the head portion and the foot portion respectively, the electric bed frame comprising: a fixed rack; a movable rack movably attached to the fixed rack; and a hitching bracket having a striding portion for being disposed on the side rack of the bed frame, and an extended portion extended from the striding portion and adapted for the fixed rack to be placed thereon. ### Claim 12 (depends on 11) The electric bed frame as claimed in claim 11, wherein the striding portion of the hitching bracket is reverse-U-shaped. ### Claim 13 (depends on 12) The electric bed frame as claimed in claim 12, wherein the striding portion of the hitching bracket has a top wall for being abutted on a top side of the side rack, an outer wall extended downwardly from an outer side of the top wall, and an inner wall extended downwardly from an inner side of the top wall for sandwiching the side rack between the outer wall and the inner wall. ### Claim 14 (depends on 13) The electric bed frame as claimed in claim 13, wherein the inner wall has a threaded hole for being screwed with a tightening member to enable an end of the tightening member to be abutted against the side rack of the bed frame. ### Claim 15 (depends on 14) The electric bed frame as claimed in claim 14, wherein the tightening member is provided at the end thereof with an abutting plate for being abutted against the side rack of the bed frame.
