Problems solved by technology

[0002] The control system usually uses a micro switch as the actuator for key state signal collection and switching. In order to drive the micro switch for state switching, a mechanism that can convert rotary motion into linear motion is needed, and the micro switch roller is pressed to achieve it; In addition, it is also necessary for the mechanism to be simple and small, easy to manufacture, assemble, replace and maintain, low in production cost, stable in execution, high in execution accuracy, and high in service life. Since there is no corresponding mechanism that can meet the use requirements, Therefore, a redesign is required

Description

technical field [0001] The invention relates to the technical field of driving mechanism design, in particular to a rotation-driven telescopic mechanism. Background technique [0002] The control system usually uses a micro switch as the actuator for key state signal acquisition and switching. In order to drive the micro switch for state switching, a mechanism that can convert rotational motion into linear motion is needed, and the micro switch roller is pressed to achieve it; In addition, it is also necessary for the mechanism to be simple and small, easy to manufacture, assemble, replace and maintain, low in production cost, stable in execution, high in execution accuracy, and high in service life. Since there is no corresponding mechanism that can meet the use requirements, Therefore, a redesign is required. Contents of the invention [0003] In order to overcome the deficiencies in the background technology, the present invention discloses a rotation-driven telescopic...
