Further, the pulling mechanism is a pull rod 21. The length of the pull rod 21 is unchanged, and when the oil cylinder 11 is extended or shortened, the pull rod 21 forms a pulling radius, so that the oil cylinder 11 rotates around the pull rod 21 in an arc shape. When the oil cylinder 11 is in a vertical state, the oil cylinder 11 is vertically arranged with the ground, the pear plate 31 is contacted with the ground level, at the moment, the object presses the oil cylinder 11, the distance between the object and the ground is shortest, and the acting force is the most stable.
