Abstract: Title: PORTABLE NAIL PULLING DEVICE WITH LEAD SCREW ACTUATION The titled invention discloses a cordless nail plucking device for extracting embedded 5 nails from wooden and similar work surfaces with reduced manual effort. The device comprises a holding block (1), a drive cabin (2), a direct current motor (3), a worm wheel (4), a worm gear (5), a lead screw (6), a puller hub (7), a wall butting tip (8), a nail holding slot (9), a nail plucking tool (10), and a power switch (11). The direct current motor (3) drives the worm gear (5), which rotates the worm wheel (4) and the 10 _lead screw (6) to convert rotary motion into controlled linear movement. The puller hub (7) moves the nail plucking tool (10) while the nail holding slot (9) securely engages the embedded nail. The wall butting tip (8) stabilizes the device against the work surface during extraction. The arrangement enables substantially axial nail removal with improved control, reduced surface damage, and enhanced operational efficiency. 15 The invention is suitable for woodworking, furniture repair, construction, renovation, and maintenance applications.
