DETAILED DESCRIPTION OF THE INVENTION

[0015] FIGS. 1 through 5 show a hammer tool 10 in accordance with the present invention. The hammer tool 10 includes a head 20 and a handle 30 tightly coupled to the head 20.

[0016] The head 20 defines a first and a second through hole 21 and 22 and a first and a second hole 23 and 24. The first hole 23 is connected to the first through holes 21 and the second hole 24 is connected to the second through holes 22 respectively. The first holes 23 extends transversely to the first through holes 21 and the second hole 24 extends transversely to the second through holes 22 respectively. The first through hole 21 is of a width W1 and the second through hole 22 is of a width W2 respectively, as shown in FIG. 4. The width W1 is the maximum width of the through hole 21. The first and the second through holes 21 and 22 are circular holes. The first hole 23 is of a width greater than the width W1 and the second hole 24 is of a width greater than the width W2 respectively,

[0017] The head 20 has an end 25 and an end 26 at opposite ends and a lateral side 27 and a lateral side 28 at opposite sides. The first and the second through holes 21 and 22 extend through the ends 25 and 26 and the first and the second holes 23 and 24 extend through the first and the second lateral sides 27 and 28 respectively. The first and the second holes 23 and 24 extend transversely to the first and the second through holes 21 and 22.

[0018] The head 20 has a working portion 29 at an end and a working portion 291 at another end. The working portions 29 and 291 are disposed oppositely in a first direction and the through hole 21 extends in a second direction transverse to the first direction. The working portion 29 has a striking face. The working portion 291 is a claw which is adapted to be used to pry an object.

[0019] The handle 30 has a first and a second connecting end 311 and 321 fixed to the head 20. The handle 30 has a first and a second medial section 31 and 32 and the first and the second connecting ends 311 and 321 extend from the first and the second medial sections 31 and 32 respectively. Each of the medial sections 31 and 32 is of a cross section different from a cross section of each of the connecting ends 311 and 321. The first and the second medial sections 31 and 32 extend parallel to each other. The first and the second medial sections 31 and 32 are disposed side by side. The first and the second medial sections 31 and 32 form at least one first and at least one second curved sections 312 and 322 respectively. The first and the second medial sections 31 and 32 are bent to form the at least one first and the at least one second curved sections 312 and 322 respectively. The at least one first and the at least one second curved sections 312 and 322 abut against each other. Since the first and the at least one second curved sections 312 and 322 abut against each other. Thus, the first and the second medial sections 31 and 32 can resist from being deformed. Particularly, each of the at least one first and the at least one second curved sections 312 and 322 has two lateral sides, and one of the two lateral sides of the at least one first curved section 312 abuts against one of the two laterals sides of the at least one second curved section 322. Moreover, each of the at least one first and the at least one second curved sections 312 and 322 has a top between the two lateral sides, and the top of the at least one first curved section 312 is spaced from the second medial section 32 and the top of the at least one second curved section 322 abuts against the first medial section 31. In addition, the embodiment discloses the at least one first curved section including two first curved sections 312 and 313 and the at least one second curved section including two second curved sections 322 and 323. Furthermore, the two first curved sections 312 and 313 are disposed between the two second curved sections 322 and 323.

[0020] The handle 30 includes the first connecting end 311 inserted through the first through hole 21 and the second connecting end 321 inserted through the second through hole 22 respectively. The first connecting end 311 abuts against an inner periphery of the first through hole 21 and the second connecting end 321 abuts against an inner periphery of the second through hole 22 respectively. The first connecting end 311 is extruded after inserting through the first through hole 21 to include at least one first positioning protrusion 314 protruding into the first hole 23 and the second connecting end 321 is extruded after inserting through the second through hole 22 to include at least one second positioning protrusion 324 protruding into the second hole 24 respectively. The first connecting end 311 is of a width W3 at where the at least one first positioning protrusion 314 is disposed and the second connecting end 321 is of a width W4 at where the at least one second positioning protrusion 324 is disposed respectively, as shown in FIG. 7. The width W3 is greater than the width W1 and the width W4 is greater than the width W2 respectively. The at least one first positioning protrusion 314 tightly abuts against an inner periphery of the first hole 23 and the at least one second positioning protrusion 324 tightly abuts against an inner periphery of the second hole 24 respectively and so the head 20 and the handle 30 are tightly coupled and prevented from moving relative to each other. The width of the hole 23 substantially equals to the width W3 at where the at least one positioning protrusion 314 is disposed and the width of the hole 24 substantially equals to the width W4 at where the at least one positioning protrusion 324 is disposed respectively. In addition, the first connecting end 311 is extruded after inserting through the first through hole 21 to include a first anti-disengagement protrusion 315 disposed outside the first through hole 21 and the second connecting end 321 is extruded after inserting through the second through hole 22 to include a second anti-disengagement protrusion 325 disposed outside the second through hole 22 respectively. The anti-disengagement protrusion 315 and 325 abut against the end 26 of the head 20. The first anti-disengagement protrusion 315 is of a width W5 greater than the width W1 and the second anti-disengagement protrusion 325 is of a width W6 greater than the first width W2 respectively. The first and the second anti-disengagement protrusion 315 and 325 are therefore able to prevent the handle 30 detaching from the head 20.

[0021] The handle 30 includes an end forming a U-turn section 33. The U-turn section 33 has a first end connecting to the first medial section 31 and a second end connecting to the second medial section 32 respectively. The U-turn section 33 is of a cross section different from the cross section of each of the medial sections 31 and 32. Each of the medial sections 31 and 32 is of a quadrilateral cross section. The U-turn section 33 is of a circular cross section.

[0022] The handle 30 has a main body made in one piece. The handle 30 has a grasp section 34 at an end. The first and the second connecting ends 311 and 321 and the grasp section 34 are at opposite ends in a longitudinal direction of the handle 30. The grasp section 34 has an ergonomic cover mounted thereon. Preferably, the cover is injection molded. The U-turn section 33 is not covered by the grasp section 34. The U-turn section 33 thus defines a hanging hole.

[0023] In view of the foregoing, the first and the second medial sections 31 and 32 are prevented from deformation. Further, once the head 20 and the handle 30 are tightly coupled with each other, they are prevented from moving relative to and disengaging from each other.

[0024] The foregoing is merely illustrative of the principles of this invention, and various modifications can be made by those skilled in the art without de parting from the scope and spirit of the invention.
