the fixed blade ( 1 ) is supported by edges on both the left and the right sides of the fixed blade support ( 2 );

the fixed blade ( 1 ) having left and right ends, each of the left and right ends are bent downwardly around the respective edges on the left and right sides of the fixed blade support ( 2 ) and tensioned downwardly along a respective outer side of each of the left and right sides of the fixed blade support ( 2 ) to lie flat against the respective outer side of the fixed blade support ( 2 ), and the fixed blade ( 1 ) is tightly fixed to the outer sides of the fixed blade support ( 2 ) by welding or riveting the left and right ends of the fixed blade ( 1 ) to the respective outer side of the fixed blade support ( 2 ) to provide the downward tension;

the fixed blade ( 1 ) is provided with hair entrance holes ( 11 ) for body hair to enter, and an inner side of the fixed blade ( 1 ) is provided with a movable blade ( 3 ), wherein the movable blade is movable backward and forward in a reciprocating manner relative to the fixed blade to cut off the body hair that extends through the hair entrance holes ( 11 );

the reciprocating electric razor head further comprises a transmission component ( 4 ) for connecting the movable blade ( 3 ) with a power device of an electric shaver;

wherein the transmission component ( 4 ) comprises a movable blade support ( 41 ) fixedly connected to the movable blade ( 3 ) and a driving mount ( 42 ) for connecting with the power device of the electric shaver; and

wherein an elongated movable blade pressing member ( 5 ) that extends along a length of the movable blade ( 3 ) and presses the movable blade ( 3 ) against the fixed blade ( 1 ) is provided between the movable blade ( 3 ) and the fixed blade support ( 2 ).

2. The reciprocating electric razor head of claim 1 , wherein the fixed blade ( 1 ) has a thickness of h, which satisfies 0<h≤0.08 mm.

3. The reciprocating electric razor head of claim 1 , wherein the hair entrance holes ( 11 ) are equally arranged on a left side and/or a right side of the fixed blade ( 1 ).

4. The reciprocating electric razor head of claim 3 , wherein hair entrance slots ( 21 ) for the body hair to enter are provided at positions on the fixed blade support ( 2 ) corresponding to the hair entrance holes ( 11 ), and the movable blade ( 3 ) is provided with cutting teeth ( 31 ) corresponding to the hair entrance holes ( 11 ) and used for cutting the body hair.

5. The reciprocating electric razor head of claim 1 , wherein the movable blade pressing member ( 5 ) comprises a body ( 51 ), wherein a middle portion of the body ( 51 ) is provided with a strip-shaped hole ( 52 ) such that the movable blade support ( 41 ) passes therethrough and slides therein, and both sides of the body ( 51 ) are provided respectively with elastic pressing plates ( 53 ) to press the movable blade ( 3 ) against the fixed blade ( 1 ).

6. The reciprocating electric razor head of claim 1 , wherein the movable blade pressing member ( 5 ) comprises a supporting portion ( 54 ) supported on the fixed blade support ( 2 ) and an elastic arm ( 55 ) for pushing the movable blade ( 3 ) upward, and the elastic arm ( 55 ) is provided with a curved portion ( 551 ) for pushing the movable blade ( 3 ) upward to press the movable blade ( 3 ) against the fixed blade ( 1 ).

7. The reciprocating electric razor head of claim 6 , wherein the fixed blade support ( 2 ) is provided with a limit block ( 6 ), wherein the limit block ( 6 ) is provided with a strip-shaped slot ( 61 ) that mates with the movable blade support ( 41 ) for restricting the movable blade support ( 41 ) from moving horizontally.

8. The reciprocating electric razor head of claim 1 , wherein a through-hole ( 32 ) is provided in a middle of the movable blade ( 3 ), and the movable blade is provided with movable blade connecting portions ( 33 ) projecting beyond a body of the movable blade ( 3 ), and the movable blade support ( 41 ) is provided with movable blade support connecting portions ( 411 ) that respectively mate with the movable blade connecting portions ( 33 ) to connect the movable blade ( 3 ) with the movable blade support ( 41 ).
