A buckling structure for a battery of a handheld power tool, having a horizontal opening end (18) formed on a handheld seat (13) of the power tool (11), and a buckling structure arranged on top of a battery base (20) and configured to mutually guide, insert and buckle into the opening end (18) to be integrally attached thereto, the buckling structure comprising:
- a receiving surface (15) formed at an inner side of the opening end (18) and configured to move forward and backward relative to a buckling surface (24) of the battery base (20), and the receiving surface (15) having a buckling groove (151) formed thereon;
- a guiding slot (221) formed at a front surface of the battery base (20);
- the guiding slot (221) extending horizontally, and having at least one guiding protrusion (223) and a leading slot (224) formed at two side slot surfaces respectively, at least one first base hole (222) formed at a center of a bottom slot surface and a limiting slot (225) and a horizontal protrusion (226) extended at a rear end;
- two receiving slots (241) formed at the buckling surface (24) respectively;
- the two receiving slots (241) disposed at two sides of the guiling slot (221) respectively and fluidly connected to the guiding slot (221);
- each one of the receiving slots (241) extending vertically and having a second base hole (242) formed thereon;
- two buckling members (25) and two second elastic elements (28);
- the two buckling members (25) disposed inside the two receiving slots (241) respectively and configured to move vertically between an upper position and a lower position along the two receiving slots (241);
- each one of the two elastic elements (28) arranged between each one of the second base holes (242) and each one of the buckling members (25) and configured to provide an upward elastic acting force to each one of the buckling members (25);
- each one of the buckling members (25) having a slab (252) extended from one side thereof and configured to insert into the guiding slot (221);
- the slab (252) having a slanted abutment surface (253);
- a pressing member (26) and a first elastic element (27);
- the pressing member (26) disposed inside the guiding slot (221) and configured to move between a front position and a rear position along the guiding slot (221);
- the first elastic element (27) arranged between the first base hole (222) and the pressing member (26) and configured to provide a forward elastic acting force to the pressing member (26);
- the pressing member (26) having a pair of guiding blocks (263) arranged corresponding to the leading slot (224) respectively, a pressing surface (261) arranged opposite from the two abutment surfaces (253), and an extension plate (264) formed at a rear end and configured to insert into the limiting slot (225), and a latching portion (262) arranged at a rear end of the extension plate (264) and configured to be retained by the guiding protrusion (223);
- and
- wherein when the battery base (20) is buckled to the handheld seat (13), the buckling member (25) is at the upper position and capable of being inserted into the buckling slot (151) of the receiving surface (15) in order to restrict the battery base (20) from moving relative to the handheld seat (13);
- when the buckling member (25) is at the lower position, it is disengaged from the buckling slot (151), thereby allowing the battery base (20) to move relative to the handheld seat (13);
- when the pressing member (26) is moved toward the rear position, the pressing surface (261) pushes against the abutment surface (253) in order to drive the buckling member (25) to move toward the lower position.
