The main feature of plastic clamps is a hand twisted design, which can be used without the need for additional tools. They use a
simple and effective mechanism to tighten items by rotating and twisting. Users only need to place the clamp in the desired
position with their fingers or palms, and then rotate the hand twisted part to tighten and lock it. These clamps typically have
adjustable lengths to accommodate items of different sizes. Their design allows users to adjust the tightening force as needed to
ensure that the items are securely fixed together. In addition, plastic clamps also have the characteristic of being reused,
allowing users to loosen and tighten them multiple times for easy adjustment or reuse.
