The purpose of the utility model is realized like this:

the utility model provides a push rod, the push rod includes the shell body, be provided with elevating system along its length direction in the shell body, be provided with an at least guide way on the lateral wall of shell body, the outer slip cover of shell body is equipped with a backing ring, and the one end of the connecting rod that passes the guide way links to each other with elevating system, and the other end is connected with the backing ring.

The utility model relates to a push rod, elevating system includes the screw rod that sets up along outer casing length direction, is provided with the screw on the spiral shell piece, and on the screw rod was arranged in soon to the spiral shell piece, the one end fixed connection of above-mentioned connecting rod in the shell was on the spiral shell piece.

The utility model relates to a push rod, elevating system includes along screw rod and the guide rail that shell length direction set up, and on the screw rod was arranged in soon to the spiral shell piece, and the lateral wall of spiral shell piece slides and sets up on the guide rail, and the one end fixed connection that above-mentioned connecting rod is located the shell is on the spiral shell piece.

The utility model relates to a push rod, the cover is equipped with the direction bearing on the connecting rod, and the direction bearing inlays and arranges in the guide way.

The utility model relates to a push rod, the screw rod is by motor drive.

The utility model relates to a push rod, the shell body is drum or square tube.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model contacts the cylindrical material through the outer shell, and the lifting mechanism is arranged in the outer shell, thereby leading the appearance to be more beautiful and the structure to be more concise; meanwhile, after the lifting mechanism is arranged in the device, no matter what power driving and structure type of the lifting mechanism is adopted, the lifting mechanism cannot be in contact with the cylindrical material, so that the device is suitable for the cylindrical structures with different specifications, and the application range of the device is greatly improved.
