This is a 3-hole 3-blade dual-mode wire stripping machine. Its core function is to strip the insulation from wires and extract the inner copper core. It is a commonly used tool for scrap recycling and electrical work.

1. Structure and Core Components
Main Body: All-metal (galvanized steel / stainless steel) structure, sturdy and durable, suitable for high-frequency use.
Adjustment Screw: Two hex bolts on top for adjusting the gap between the upper and lower rollers/blades, accommodating wires of different thicknesses and preventing copper cores from being cut.
Gear Transmission System: Multiple sets of internal gears and rollers that feed the wire while the blades strip the insulation.
Drill Interface: Transmission shaft protruding from the right side can connect directly to a handheld drill, upgrading the manual tool to electric and greatly improving efficiency.
Fixed Base: Metal base plate with mounting holes at the bottom for securing the machine to a workbench for more stable operation.

2. Core Functions and Features
Dual-Mode Drive
Manual Mode: Equipped with a hand crank, suitable for small batches and outdoor situations without electricity, flexible and portable.
Electric Mode: Connecting a handheld drill enables semi-automatic operation, with efficiency dozens of times higher than manual, suitable for large-scale cable processing.
Wide Compatibility: Can handle wires/cables of various diameters, from thin household wires to thick industrial cables.
Durable Structure: All-metal gears and rollers, low wear, long lifespan, easy maintenance, blades replaceable.
Easy Operation: Simply insert the wire into the rollers and rotate the drive to automatically strip the insulation; even beginners can quickly operate it.

3. Usage Scenarios and Advantages
Applicable Scenario | Core Advantage
Scrap wire/cable recycling | Efficiently strips insulation, quickly extracts copper cores, improves recycling efficiency
Renovation, electrical work | Handles wires in bulk, replaces manual stripping, reduces labor intensity
Small factories, repair workshops | Prepares cables, strips in bulk, accommodates multiple wire specifications

4. Usage Precautions
When adjusting the screws, control the roller/blade gap to only cut the insulation layer to prevent cutting the copper core and reducing recycling value.
When using a drill, control the speed to avoid wire jamming or equipment damage.
Regularly lubricate gears and shafts, replace blades promptly after wear to extend lifespan.
Always adjust the gap according to wire diameter to prevent stripping failure or tool damage.
