Abstract:
An electric hair cutter head tooth pitch adjusting device. The device comprises a machine body (10), a guide rail (11), a lower cutter rest (12), and a cutter head (30); an adjusting device (20) is connected to one side of the lower cutter rest (12); the adjusting device (20) comprises a rocker (21), a rocker shaft sleeve (22), a rocker fixed wheel (23), a rocker movable wheel (24), a gear spring (25), a stop gasket (26), and a gear fixing screw (27); one end of the rocker shaft sleeve (22) penetrates through the top end of the rocker (21) to be connected to the guide rail (11), the rocker fixed wheel (23) and the rocker movable wheel (24) are matched and sleeved on the rocker shaft sleeve (22), one end of the gear spring (25) is connected to the rocker movable wheel (24), the other end of the gear spring is connected to the stop gasket (26) and sleeved on the rocker shaft sleeve (22), and the gear fixing screw (27) penetrates through the rocker shaft sleeve (22) to be connected to the guide rail (11). The adjusting device (20) can smoothly adjust the lower cutter rest (12) in a stepless mode without hindrance, and the adjusting device (20) can achieve multi-gear setting by means of cooperation of the fixed wheel (23) and the movable wheel (24) of the adjusting device (20); moreover, because an acting force does not pass through the gear fixing screw (27), the screw (27) would not loosen due to the length of time used; and the continuous restoring force of the spring keeps the force of adjusting the rocker (21) unchanged all the time.
