Feature: 1. Multiple specifications of clamping ports correspond to motherboards of different thicknesses, and the clamping is firm, ensuring that the motherboard does not deviate during use. 2. The chuck is designed to rotate and fix the motherboard at the desired angle through an elastic knob. 3. Adjustable opening distance, suitable for clamping various sizes of motherboards. 4. Removable soldering iron holder, suitable for placing soldering iron pens, made of high-temperature resistant materials to prevents accidental contact and scalding. Removable design, convenient in use. 5. The surface of the clamping port is flat and free of burrs, which is not easy to damage the motherboard/circuit board. 6. Bottom antiskid rubber pad, stable and not easy to move.
