If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0024] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0025] See also Figure 1-5The utility model provides a technical solution: a motor vibrator with adjustable amplitude and frequency, comprising an electric motor 1, a rotating shaft 3, an adjusting sliding block 12, a motor rear shell 16 and a vibrator cam 2, wherein the motor rear shell 16 is fixedly connected to one side of the electric motor 1, the rotating shaft 3 is installed on the side of the electric motor 1 away from the motor rear shell 16, an embedding groove 11 is provided on the side of the adjusting sliding block 12 close to the electric motor 1, an end of the rotating shaft 3 away from the electric motor 1 is fixed in the embedding groove 11, a sliding groove 9 is provided on the side of the vibrator cam 2 close to the electric motor 1, the adjusting sliding block 12 is slidably connected in the sliding groove 9, a distance sensor 13 is fixedly connected to the bottom of the adjusting sliding block 12, an amplitude adjustment structure is arranged on the vibrator cam 2, and the amplitude adjustment structure comprises two electric telescopic rods 5 and two mounting seats 10, the two electric telescopic rods 5 are fixedly connected to the bottom of the adjusting sliding block 12, and the two mounting seats 10 are fixedly connected to the inner bottom wall of the sliding groove 9.

[0026] A positioning groove 15 is provided on the top of the two mounting seats 10, and a pulling groove 14 connected to the positioning groove 15 is provided on both sides of the two mounting seats 10. A mounting groove 4 is provided at the bottom end of the two electric telescopic rods 5. The two pulling grooves 14 on the two mounting seats 10 are slidably connected with a limit rod 6, and the two limit rods 6 are fixedly connected with a pull plate 8 at one end away from the corresponding mounting seat 10. The outer surfaces of the two limit rods 6 are sleeved with springs 7, one end of the two springs 7 is fixedly connected to the corresponding mounting seat 10, and the two ends of the two springs 7 away from the corresponding mounting seat 10 are fixedly connected to the pull plate 8. The two limit rods 6 are slidably connected to the corresponding mounting groove 4, and the bottom ends of the two electric telescopic rods 5 are slidably connected to the corresponding positioning groove 15.

[0027] Furthermore, when using the device, the two electric telescopic rods 5 are started by connecting an external power source. The two electric telescopic rods 5 are contracted and drive the vibrator cam 2 to move upward through the corresponding mounting seat 10, so that the center position of the vibrator cam 2 changes accordingly, so as to adjust the distance from the center of the vibrator cam 2 to the rotating shaft 3, and the distance sensor 13 will automatically sense the distance between the vibrator cam 2 and the adjusting sliding block 12. The closer the center of the vibrator cam 2 is to the rotating shaft 3, the smaller the amplitude of the electric motor 1. At the same time, the farther the center of the vibrator cam 2 is from the rotating shaft 3, the larger the amplitude of the electric motor 1. When the vibrator cam 2 needs to be removed, the user pulls the pull plate 8, and the pull plate 8 drives the two limit rods 6 to disengage from the corresponding electric telescopic rods 5. When the two limit rods 6 are disengaged from the corresponding electric telescopic rods 5, the corresponding springs 7 are stretched, so that the bottom ends of the two electric telescopic rods 5 can be disengaged from the corresponding mounting seats 10, thereby facilitating the removal of the vibrator cam 2.

[0029] Through the cooperation of two mounting seats 10, two limit rods 6, two springs 7 and a pull plate 8, the two limit rods 6 can fix the two electric telescopic rods 5 under the action of the corresponding springs 7, thereby facilitating the removal of the vibrator cam 2 and further facilitating the replacement of the vibrator cam 2, making the removal of the vibrator cam 2 more convenient.

[0030] Working principle: by connecting an external power supply to start the two electric telescopic rods 5, the two electric telescopic rods 5 shrink and drive the vibrator cam 2 to move upward through the corresponding mounting seat 10, so that the center position of the vibrator cam 2 changes accordingly, so as to adjust the distance from the center of the vibrator cam 2 to the rotating shaft 3, and the distance sensor 13 will automatically sense the distance between the vibrator cam 2 and the adjusting sliding block 12, and the closer the center of the vibrator cam 2 is to the rotating shaft 3, the smaller the amplitude of the electric motor 1, and at the same time, the farther the center of the vibrator cam 2 is from the rotating shaft 3, the larger the amplitude of the electric motor 1, when the vibrator cam 2 needs to be removed, the user pulls the pull plate 8, and the pull plate 8 drives the two limit rods 6 to disengage from the corresponding electric telescopic rods 5, so that the bottom ends of the two electric telescopic rods 5 can be disengaged from the corresponding mounting seat 10, thereby facilitating the removal of the vibrator cam 2.

[0031] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
