The output shaft on the motor drives the shaft I3 to synchronously rotate, the rotating disc 4 rotates along with the shaft, and the motor is a power output motor in the electric toothbrush; and a second shaft 7 is used for providing support for the rotation of the brush head test piece 6. Due to the fact that the first deflector rod 5 is arranged on the rotary table 4 in an eccentric mode, after the first deflector rod 5 rotates continuously along with the rotary table 4, the whole brush head testing piece 6 swings by taking the vertical central axis of the second shaft 7 as a rotation center under the cooperation of the guide through groove 8, and in the actual use process, the brush heads of different manufacturers are different in swing driving modes, but the brush head testing piece 6 can swing at a high frequency; the amount of the oscillation is the amount of the main vibration offset of the brush head test piece 6. The brush head test piece 6 drives the marking pen 71 to swing, and when the bottom of the marking pen 71 is in contact with the upper surface of the red PH test paper 2, a trace can be left on the upper surface of the red PH test paper 2; the repeated swinging can leave obvious traces on the red PH test paper 2, the traces penetrate through the red PH test paper 2 at a overlooking angle, and the traces of the marker pens 71 left in the front and back directions of the red PH test paper 2 are the main vibration offset of the brush head test piece 6. Secondly, through moving the second device of transporting and moving the device one, under the quick swing of brush head test piece 6, can simulate the condition that the foam on the brush head was sprayed in the use, can further assist the main vibration offset of judging brush head test piece 6 through the vestige that alkaline soap liquid left on red PH test paper 2. When the first moving device and the second moving device and the like mechanism operate, mechanical energy is consumed when the brush head testing piece 6 swings rapidly, so that the swing amplitude of the brush head testing piece 6 is reduced, and the resistance of the lip teeth to the brush head during operation is simulated in the actual use process, so that the main vibration offset of the brush head testing piece 6 in the test process is close to the main vibration offset of the brush head in the actual use process, and the test result is more accurate. The first poking piece 9 and the second poking piece 10 on the brush head testing part 6 are driven to synchronously swing through the swinging of the brush head testing part, the second poking rod 14 on the main rotating wheel 13 is pushed through the matching of the first poking piece 9 and the second poking piece 10 in the swinging process, and the second poking rod 14 arranged on the main rotating wheel 13 is pushed through connection, so that the one-way rotation of the main rotating wheel 13 and the third shaft 12 on the U-shaped box body 11 is finally realized. The third shaft 12 drives the stirring blades 15 to rotate in the U-shaped box body 11, so that the alkaline soap liquid in the U-shaped box body 11 is repeatedly stirred, the alkaline soap liquid is easier to foam, and the toothbrush head is convenient to rapidly swing to drive toothpaste foam on the toothbrush head to splash in the subsequent process of simulating tooth brushing; meanwhile, the alkaline soap liquid is arranged and can be in contact with the red PH test paper 2, so that the color of the red PH test paper 2 is changed, the red PH test paper 2 becomes blue after encountering the alkaline soap liquid in the U-shaped box body 11, and the alkaline soap liquid is formed into tiny liquid drops on the brush hair part 61 due to rapid swinging, traces of the small liquid drops are left on the red PH test paper 2, the main vibration offset of the brush head test piece 6 can be simulated, and the main vibration offset of the brush head test piece 6 can be visually displayed.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
