[0002] There are many mechanical equipments used in logging projects, including logging engineering vehicles. When logging projects are carried out, wood can be sawed from the bottom and cut into equal lengths. Such engineering vehicles can also be used for high-altitude logging operations in cities. The existing logging blade arm structure of logging engineering vehicles is controlled by a mechanical arm, and the trunk is fixed by a clamp, and then the saw blade is pushed toward the trunk to move, so as to saw the trunk and obtain wood. However, such logging blade arms are only suitable for thinner trunks. For trunks with a diameter greater than 1m, such saw blades are very large, and the radius must exceed 1m, so a larger device for pushing the saw blade is required, and the existing clamps cannot be adjusted in size, and cannot be completely closed and fixed for trunks with larger diameters.
