Three sewing machines with one motor

The invention relates to three sewing machines integrated with one motor, in particular to three sewing machines which are provided with an operation interface module and a control module in a sewing machine casing to realize the integration of the motor.

According to the conventional sewing machine, a motor is usually disposed under the working platform of the sewing machine, and a control box is connected to the motor, and the control box has a control button and a pedal, and during the implementation, the user The speed of the motor can be controlled by pressing the control button to switch the operation and by pedaling the pedal. However, in order to prevent the user from accidentally touching the motor, the motor is mostly disposed on the side of the working platform away from the user, and the control box is away from the user along with the position of the motor, so that the user needs When you bend over to the work platform, you can press the control button to switch, which will cause inconvenience in use.

In view of the above, the Republic of China Patent Publication No. M373931 discloses a sewing machine and a sewing machine motor used in the sewing machine. The sewing machine motor includes a control box and a fixing seat, and the control box is provided with a touch device for pressing by a user. And a motor and a speed control device are disposed on the fixed seat, and the speed control device is connected with a pedal, wherein when the sewing machine motor is assembled to the sewing machine, the motor and the control box can be separated from each other.
