[0003] The following problems exist in the existing technology:
[0004] In the current technology, the reciprocating motion in automated production lines is mostly achieved by cylinders. The reciprocating motion structure driven by cylinders is not compact enough and the operation is not smooth and continuous. To address these issues, we propose a lightweight electric cylinder. Utility Model Content

A transmission rod is provided on the top of the rotating disk, and a first fixing ring is fixedly connected to one end of the transmission rod, while a second fixing ring is fixedly connected to the other end of the transmission rod.
[0008] Preferably, a drive shaft is fixedly connected to the top of the rotating disk, and the inside of the first fixing ring is rotatably connected to the surface of the drive shaft.
[0009] Preferably, a support plate is fixedly connected to the top of the motor, and a sliding frame is fixedly connected to the top of the support plate. The sliding frame has an I-shaped structure, and a sliding block is slidably connected to the surface of the sliding frame.
[0010] Preferably, a receiving plate is fixedly connected to the top of the sliding block, and a positioning shaft is fixedly connected to the top of the receiving plate. The surface of the positioning shaft is rotatably connected to the inside of the second fixing ring.
[0011] Preferably, a moving rod is provided on one side of the receiving plate, one end of the moving rod is fixedly connected to the receiving plate, and the other end of the moving rod passes through the inner wall of the mounting box and extends outward from the mounting box.
[0012] Preferably, the other end of the moving rod is provided with a reciprocating cylinder, and a docking block is fixedly connected to the side of the reciprocating cylinder facing the moving rod. Two docking blocks are provided.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0015] The motor of this invention can drive a rotating disk to rotate around its own axis. The rotation of the rotating disk drives a drive shaft to rotate synchronously around the axis of the rotating disk. The rotation of the drive shaft drives a first fixed ring to rotate synchronously around the axis of the rotating disk. The rotation of the first fixed ring drives a second fixed ring to rotate synchronously around the axis of the positioning shaft via a transmission rod. The rotation of the second fixed ring drives a sliding block to slide synchronously back and forth along the sliding frame. The receiving plate moves and drives a reciprocating cylinder to perform synchronous telescopic reciprocating motion via a motion rod. This design solves the shortcomings of the existing technology, abandoning the traditional method of using a cylinder to drive a reciprocating cylinder to perform telescopic reciprocating motion. This design is more continuous than cylinder motion, and has lower cost and quality, greatly reducing production costs. Attached Figure Description
