Technical Field

[0001] The utility model relates to the field of plastic product clamping equipment, in particular to a plastic product clamping tool. Background Art

[0002] The plastic product clamping tool is an auxiliary device used in the production and processing of plastic products to clamp and fix the shaped plastic products so that they can be better processed later. It has been widely used in the field of clamping tool technology and is easy to start to clamp and limit plastic products.
