1. An animal tail-wagging simulation device comprising:
a housing; a circuit board mounted in the housing and provided with a driving coil; a swinging arm mounted in the housing, the swinging arm being provided with a U-shaped portion at an upper end thereof, the swinging arm being pivotably coupled with the housing through a first shaft, the position where the swinging arm is pivotably coupled with the housing is located below the U-shaped portion, the driving coil being disposed in a middle of the U-shaped portion, two sides of the U-shaped portion being provided respectively with two permanent magnets that associate with the driving coil, whereby when the driving coil is energized, electromagnetic field is generated and interacts with the permanent magnets to thereby drive the swinging arm to swing; a first swinging unit provided at a lower end of the swinging arm, the first swinging unit comprising a first swinging plate pivotably coupled with the swinging arm through a second shaft, and an adjustable first counterweight member provided at an upper end of the first swinging plate, the first counterweight member being in the form of one or more metal plates; and a second swinging unit provided at a lower end of the first swinging unit, the second swinging unit comprising a second swinging plate pivotably coupled with the first swinging plate through a third shaft, and an adjustable second counterweight member provided at an upper end of the second swinging plate, the second counterweight member being in the form of one or more metal plates. |
