| titleOfInvention | Safety hammer |
| abstract | The invention provides a safety hammer, which comprises a hammer head and a grab handle; the hammer head comprises a metal column block, and an axial slide way with an axial slide column arranged inside is arranged in the hammer head; the lower end of the axial sliding column extends to the lower part of the metal column block and then is connected with the hard round block; a supporting pressure spring is connected between the metal column block and the hard round block; metal stripes are distributed on the lower bottom surface of the hard round block at equal intervals; a battery and an electromagnet which form a series circuit are arranged in the axial sliding column; after each adjacent metal stripe is electrically lapped, the battery and the electromagnet form a series circuit; the middle section of the axial sliding column is provided with a row of ring grooves, and the inner wall of the axial sliding way is provided with a row of transverse pore channels internally provided with transverse sliding blocks; when the electromagnet is electrified, each transverse sliding block is sucked into the annular groove to axially lock the axial sliding column; when the electromagnet is powered off, the hemispherical end of the transverse slide block is forced to retract into the transverse hole. The safety hammer has higher safety in the process of knocking the nail. |
