  "title": "Combination tool having a hammer",
  "abstract": "A combination tool includes a hammer having a head, a handle portion and a neck part, an accessory tool for attachment to the head, and an attachment part connected to the accessory tool and including a socket to receive a hammering end of the head, two retaining walls extending respectively on two sides of the socket to retain therebetween at least the neck part, and a clamping part for pressing the neck part against the socket, thereby retaining removably the accessory tool on the hammer.",
  "claims": [
    "1. A combination tool comprising: a hammer having a head, a handle portion and a neck part between said head and said handle portion; an accessory tool for attachment to said head; and an attachment part connected to said accessory tool and including a socket disposed adjacent to said accessory tool to receive a hammering end of said head, two opposite retaining walls extending respectively from two sides of said socket in a direction away from said accessory tool, and a clamping part for pressing said neck part against said socket, said clamping part being disposed between said retaining walls opposite to said socket.",
    "2. The combination tool as claimed in claim 1, wherein said handle portion of said hammer includes a pair of lever handles pivotally connected together, said head having two jaw-like components respectively connected to said lever handles, said hammering end being integral with one of said components.",
    "3. The combination tool as claimed in claim 2, wherein the other one of said components is formed with a claw.",
    "4. The combination tool as claimed in claim 3, wherein said accessory tool is an axe.",
    "5. The combination tool as claimed in claim 1, wherein said attachment part further includes a cross piece disposed across said retaining walls to abut against said neck part opposite to said clamping part.",
    "6. The combination tool as claimed in claim 5, wherein said cross piece is a rod penetrating through said retaining walls.",
    "7. The combination tool as claimed in claim 1, wherein said attachment part further includes a transverse wall interconnecting said retaining walls opposite to said socket, said clamping part including a press block mounted movably on said transverse wall and having a press face to press against said neck part, said press block being movable between said retaining walls toward and away from said transverse wall, said retaining walls preventing said press block from rotation.",
    "8. The combination tool as claimed in claim 6, wherein said attachment part further includes a locking screw threadedly extending through said transverse wall and having one end fixed to said press block.",
    "9. The combination tool as claimed in claim 7, wherein said attachment part further includes a coiled spring, said locking screw having a screw head extending outwardly of said transverse wall, said coiled spring being sleeved around said locking screw between said screw head and said transverse wall, said transverse wall having a recess receiving said coiled spring.",
    "10. The combination tool as claimed in claim 1, further comprising a holder attached to one of said retaining walls, said one of said retaining walls having an outer face formed with an indented part to receive and retain said holder.",
    "11. A device for combination with a hammer having ahead, a handle portion and a neck part between the head and the handle portion, comprising: an accessory tool adapted for attachment to the head; and an attachment part connected to said accessory tool and including a socket which is disposed adjacent to said accessory tool and which is adapted to receive a hammering end of the head, two opposite retaining walls extending respectively from two sides of said socket in a direction away from said accessory tool, and a clamping part adapted to press the neck part of the hammer against said socket, said clamping part being disposed between said retaining walls opposite to said socket.",
    "12. The combination tool as claimed in claim 11, wherein said accessory tool is an axe.",
    "13. The combination tool as claimed in claim 11, wherein said attachment part further includes a cross piece disposed across said retaining walls and adapted to abut against the neck part of the hammer opposite to said clamping part.",
    "14. The combination tool as claimed in claim 13, wherein said cross piece is a rod penetrating through said retaining walls.",
    "15. The combination tool as claimed in claim 11, wherein said attachment part further includes a transverse wall interconnecting said retaining walls opposite to said socket, said clamping part including a press block mounted movably on said transverse wall and having a press face, said press block being movable between said retaining walls toward and away from said transverse wall, said retaining walls preventing said press block from rotation.",
    "16. The combination tool as claimed in claim 15, wherein said attachment part further includes a locking screw threadedly extending through said transverse wall and having one end fixed to said press block.",
    "17. The combination tool as claimed in claim 16, wherein said attachment part further includes a coiled spring, said locking screw having a screw head extending outwardly of said transverse wall, said coiled spring being sleeved around said locking screw between said screw head and said transverse wall, said transverse wall having a recess receiving said coiled spring.",
    "18. The combination tool as claimed in claim 11, further comprising a holder attached to one of said retaining walls, said one of said retaining walls having an outer face formed with an indented part to receive and retain said holder."
