The rotary steering engine 76 rotates the partition plate 73 by 90 degrees through the dividing plate, the clamping plate electromagnetic valve 75 is electrified to execute repeated actions, and one throwing task can be single throwing or continuous throwing, and at most four throwing tasks can be performed continuously.
Folding principle of the arm 2: when the machine body 1 is unfolded after the task is executed, the machine arm 2 is lifted upwards until the locking rod 45 is hooked by the buckle 46 to complete locking. When the arm 2 is lowered after the task is completed, the pressing pin 44 is pressed downward, the locking lever 45 is released from contact with the buckle 46, the arm 2 is lowered, and the pressing pin 44 and the locking lever 45 are reset under the action of the locking reset spring 47.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
