The corresponding pry bar can drive the worm to rotate conveniently and smoothly after being inserted into the pry bar hole.
In the worm drive type clamp, the first connecting plate and the second connecting plate can be kept in surface contact.
In the worm drive type hoop, the second body is provided with a concave locking hole, and two ends of the pry bar can be embedded in the locking hole and the pry bar hole respectively.
After the two ends of the pry bar are respectively embedded in the locking hole and the pry bar hole, the worm can be locked, and the first body and the second body are stably locked.
Compared with the prior art, the worm transmission type clamp has the advantages that the first body and the second body are stably buckled together after the worm is rotated through the pry bar, and therefore the clamp is convenient to assemble and disassemble.
Meanwhile, the two ends of the prying bar are respectively connected to the worm and the second body, so that the first body and the second body are stably locked, the stability is high, the structure is compact, and the prying bar has high practical value.
