The multi-functional four-pongs

The multi-functional four-pongs adjustable directional movement clamp is called multi-functional training clamp, and in China it is called universal clamp. Thanks to the proprietary design of the top cable, this clamp can be attached directly to the iron rod of the tripod without a separate cross clamp. In the middle is the steering structure, which can be more convenient to set up and more flexible during the experiment. The clamp has a cork gasket inside. This design is more convenient and does not slip when clamping glassware, with too much force to break the glass tube is not easy.
