发明名称 Post pulling mechanism
摘要 A manual post puller mechanism having a lever extendable for increasing the amount of leverage applied for pulling the post from the ground, the lever being securable within a base and serving as a handle graspable by the operator for carrying the mechanism between locations. A chain extends downwardly from a chain engaging front portion of the lever which includes slots that allow the position of the chain to be adjusted so as to vary the amount of leverage applied to the post. A post holder mechanism carried at the bottom of the chain engages the post and defines an enclosed generally rectangular opening that receives the post. A pair of pivot plates coupled with the lever generally hinder an operator's fingers from being pinched during post pulling operations.
