a power mechanism is also arranged in the telescopic mechanism;

the power mechanism controls the telescopic mechanism to stretch and retract so as to drive the fork plate to move.

Furthermore, telescopic machanism includes the urceolus with fixing base fixed connection, the inside inner tube of urceolus is located to the cover.

Furthermore, one end of the inner cylinder is sleeved inside the outer cylinder, and the other end of the inner cylinder extends out of the outer cylinder and is fixedly connected with the fork plate.

Furthermore, the power mechanism comprises an air cylinder and an air cylinder rod arranged at the output end of the air cylinder, the air cylinder is fixedly connected with the inside of the outer cylinder, and the air cylinder rod is fixedly connected with the inside of the inner cylinder.

Furthermore, two first shaft holes are formed in two opposite side walls of the outer cylinder, a first connecting shaft is arranged between the two first shaft holes, and the bottom of the air cylinder is fixedly connected with the first connecting shaft.

Furthermore, two second shaft holes are formed in two opposite side walls of the inner cylinder, a second connecting shaft is arranged between the two second shaft holes, and the tail end of the air cylinder rod is fixedly connected with the second connecting shaft.

Furthermore, a reinforcing plate is arranged between the fixed seat and the outer barrel.

The utility model discloses telescopic wrecker drags and pulls device's useful part: the utility model solves the defect that the traditional dragging device can only drag by lifting and folding the supporting arm. The telescopic mechanism is arranged in the towing device, so that the fork plate on the upper part of the towing device can move up and down, and the towing device can approach the axle, the bumper and the plate spring of the trailer actively, thereby realizing towing operation. And because the upper plugboard can stretch and move, the utility model can drag vehicles with chassis of different heights.
