The toothbrush comprises a toothbrush head (1), a toothbrush handle (2), a spiral pushing rod (3), a rotary cover cap (4) and a pushing sheet (5). The toothbrush head (1) consists of bristles (11) and a toothbrush head bar (12). The rotary cover cap (4) is fixedly connected to a rear end of the spiral pushing rod (3). Internal portions of both the toothbrush head bar (12) and the toothbrush handle (2) are round cavities. The rotary cover cap (4) fits a rear end of the toothbrush handle (2) in a movable mode. An inner wall of the rotary cover cap (4) is provided with 1-4 protruding points (41) matching a circle of grooves (21) on an outer wall of the rear end of the toothbrush handle (2). A front section of the spiral pushing rod (3) is a toothpaste outlet switch (31), and a middle section is a connecting section (32), and a back section comprises a vane section (33) and a threaded rod section (34). The front section and the middle section of the spiral pushing rod (3) are mounted in the cavity of the toothbrush head bar (12), and the back section of the spiral pushing rod (3) is mounted in the cavity of the toothbrush handle (2). The pushing sheet (5) has a screw-thread fit with the threaded rod section (34) of the spiral pushing rod (3). The simple design structure enables squeezing a fixed amount of toothpaste each time, thus preventing unused toothpaste in the toothbrush handle from being polluted, and being convenient for the disabled with a single hand and the blind to use.
