[0022] Reference Figures 1 to 3 The embodiments of the present utility model are further described.

[0023] The specific structure of this embodiment includes a casing 1, a suction cup 2, a vibration motor 3, a pressure handle 4 and a power unit 5. The pressure handle 4 is connected to the suction cup 2 through a keel 41. The suction cup 2 is placed at the bottom of the casing 1. The vibration motor 3 is placed in the inner cavity of the casing 1. The casing 1 is provided with a main handle 6 and a sub-handle 7.

[0024] A control switch 8 for controlling the driving of the vibration motor 3 is provided on the housing 1. The control switch 8 is associated with the power unit 5 and the vibration motor 3. The control switch 8 controls the vibration motor 3 through a drive circuit so that the drive circuit converts the signal of the control switch 8 into an appropriate voltage, current or frequency to control the operation of the vibration motor 3.

[0025] The driving circuit includes a signal processing module and an execution module. The control switch 8 inputs the control signal to the signal processing module. The signal processing module controls the execution module through a PWM pulse signal. The execution module adjusts the vibration frequency of the motor. It specifically includes an Arduino Uno and an L298N H-bridge driver module, wherein the Arduino Uno is used to receive the signal of the control switch 8, and then converts the signal of the control switch 8 into a PWM signal by writing an Arduino code. The L298N H-bridge driver module is used to receive the PWM signal generated by the Arduino and convert it into an appropriate voltage and current to control the vibration motor 3. The power supply unit is a detachable battery.

[0026] The specific control process is as follows: the user sends a command through the control switch 8;

[0027] After receiving the instruction, Arduino generates the corresponding PWM signal according to the program code;

[0028] The PWM signal is converted into appropriate voltage and current through the L298N H-bridge driver module;

[0029] The current is transmitted to the vibration motor 3 to control the vibration frequency;

[0030] The vibration motor 3 vibrates accordingly according to the change of the PWM signal, thereby realizing the stepless speed change function.

[0031] One end of the auxiliary handle 7 has a tongue 71 movably connected to the housing 1, and an inner cavity 70 is formed in the auxiliary handle 7.

[0032] The housing 1 has a docking portion 10 for connecting with the tongue 71, and the docking portion 10 has an active chamber 100 for the tongue 71 to extend into. A spring piece 9 is provided in the active chamber 100, and the spring piece 9 is sleeved on the outside of the tongue 71. The spring piece 9 is U-shaped, and the length of one pin is greater than that of the other pin. The long pin extends into the inner cavity 70 of the auxiliary handle 7, and the short pin is placed in the active cavity. The inner wall of the active cavity has a supporting portion for contacting with the spring piece 9. The installation of the spring piece 9 can reduce the impact of vibration on the auxiliary handle 7.

[0033] The auxiliary handle 7 is provided with an opening 701 for the spring 9 to extend into, and the diameter of the opening 701 is larger than the thickness of the spring 9, so as to form a movable path for the auxiliary handle 7 to rotate relative to the housing 1. The inner wall of the inner cavity 70 of the auxiliary handle 7 is provided with a protrusion for the spring 9 to resist.

[0034] When the paving machine is working, the operator holds the main handle 6 with one hand and the auxiliary handle 7 with the other hand. During this period, the auxiliary handle 7 is pressed downward, so that the spring piece 9 will elastically deform downward. When the paving machine vibrates, the spring piece 9 will absorb the vibration of this part and reduce the vibration force on the hand. The spring piece 9 is made of elastic material. In addition, the installation method of the spring piece 9 can reduce the possibility of shaking of the auxiliary handle 7.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
