[0002] A knob control is a mechanical or electronic control element that the user can rotate to change a parameter or select a different operating mode. The knob outputs an analog signal by changing the resistance value of the potentiometer. This signal is sent to the motor driver to adjust the speed of the motor, or it is connected to an encoder, which converts the rotation of the knob into digital signals. These signals are read by the microcontroller and converted into control instructions for the motor. Knob control devices are still important control elements in many fields because of their easy operation and durability.

The mounting block 103 is installed on the gear plate 801, and the knob adapter block 101 can be installed on the mounting block 103. Since a plurality of mounting holes 104 are provided on both sides of the top of the mounting block 103, the installation width between the knob adapter blocks 101 can be adjusted, so that the knob adapter block 101 can be installed and used in conjunction with various products with knobs to realize product control switching.

[0025] Among them, a blocking position 201 is set on the side of the fixed frame 2 close to the pushing member 4, and blocks 401 are set on both sides of the outer end of the pushing member 4. A sliding protrusion 301 is set on the motor rotating member 3, and a sliding lifting platform 402 is set on the top of the pushing member 4.
