[0002] At present, segmented garden machines such as high-branch shears and high-branch saws adopt a two-stage combination method, that is, the aluminum tube combination of the front cutting head part and the aluminum tube combination of the rear engine part to form garden machines for different purposes. There is no extension between the two sections of equipment. Functional connection structure, due to its limited working length range, when trimming garden crops with a wide area and high height, it is necessary to use some auxiliary tools such as height-increasing tools, which not only brings inconvenience to the actual operation, but also low operating efficiency , the operation effect is poor, and it also increases the safety hazards during the pruning operation. Therefore, there is an urgent need for a garden operation that can perform pruning operations on garden crops with a wide area and high height, high operation efficiency, good operation effect, and good safety. mechanical
