This application relates to a hoisting tool for small-sized seedlings, belonging to the field of seedling hoisting. The device includes two symmetrical connecting rods, which are rotatably connected to a rotating rod via a pivot. The surfaces of the two rotating rods are rotatably connected via the pivot. A chain is provided on the rear side of each rotating rod, and a fixing block is provided at the top of the rear rotating rod. A slidable sliding pin is provided through the right side of the surface of the fixing block. One end of the chain is fitted onto the surface of the sliding pin. Circular columns are fixedly connected to both the front and rear sides of the sliding pin, and a circular block is fixedly connected to the bottom of the sliding pin. This application allows the connecting rods, rotating rods, and arc-shaped clamps to work together, enabling the two arc-shaped clamps to directly clamp small soil balls, wrap the chain around the surface of the tree trunk, and then, through the cooperation of hooks, sliding pins, and circular columns, the two ends of the chain are hooked onto the surfaces of the hooks and circular columns, thus securing the chain.

The present invention relates to a micelle complex and a drug carrier. By supporting hydrophobic manganese oxide particles in the micelles, the complex is stably protected in vivo and easily delivered to a tumor site. Further, the micelles have a hydrophilic portion and a hydrophobic portion bound by a reactive oxygen species (ROS) cleavable linker in order to be degraded in response to a reactive oxygen species of a target site, and thus can efficiently release the hydrophobic manganese oxide particles. The released hydrophobic manganese oxide particles generate oxygen and changes the microenvironment of the target site, and thus may enhance the therapeutic effect of a drug carried on the micelles.
