[0030] The embodiment of the present invention discloses a mechanism that facilitates linear lifting and rotation, such as Figure 1 As shown, it includes: a fixed bracket 1 for fixing, a mobile bracket 2 for free lifting and rotation, a stepper motor 3, a reduction mechanism 4 and a straight-axis guide rod 5. The stepper motor 3 and the reduction mechanism 4 are installed on the fixed bracket 1, and the straight-axis guide rod 5 passes through the mobile bracket 2 and is positioned and installed on the fixed bracket 1. The fixed bracket 1 is provided with a thrust arm 6 for pushing the mobile bracket 2 to move, and the thrust arm 6 is connected to the mobile bracket 2.

[0031] It should be noted that, through the driving action of the motor, the movement of the thrust arm 6 drives the mobile bracket 2 to rise and fall, the movement of the pull rod 24 drives the rotating shaft 23 to rotate, and then the mobile bracket 2 is rotated, thereby providing a mechanism that is convenient for linear lifting and rotation, which is easy to assemble and has superior cost.
