Furthermore, the inner wall of the slotted hole is provided with an internal thread matched with the lead screw. When the slotted hole is not provided with the threads, after the screw rod is downwards adjusted to the compression spring, an elastic space is formed between the upper groove and the lower groove, after the threads are arranged, a rigid space is formed between the upper groove and the lower groove, and the spring plays a role in limiting.
The utility model has the advantages that: the utility model discloses be equipped with adjustable cocoon presss from both sides the hole, combine to press from both sides the outstanding blade in hole upper portion, can cut the cocoon to unidimensional cocoon, improve the regularity of cutting cocoon back cocoon, through the outstanding length of control blade, can effectively avoid cutting the silkworm chrysalis, the utility model is simple in operation, can obviously improve and cut the cocoon speed, and eliminated the potential safety hazard when cutting the cocoon.
