The specific embodiment:

Shown in accompanying drawing 1 and accompanying drawing 2, the utility model comprises keeper 1, clamping ring 2 and handle body 3, wherein, keeper is square, its central authorities are provided with a through hole 11, four drift angles are made as arc sections 12 respectively, in being respectively equipped with hook part 13 in arc sections 12, and are provided with four fixing holes 14 on the surface of contiguous drift angle;

Clamping ring 2 is embedded in the interior lid 31 of handle body 3, its inner rim is provided with and is the crosswise arrangement, and be the groove 21 of circular arc, in the present embodiment, these groove 21 formed circle footpaths are slightly larger than keeper 1, are provided with the rank portion 22 of the proper width that extends internally between this groove 21, and are provided with a hole slot 23 in its side, be provided with first fixed leg 24 and second fixed leg 25 in hole slot 23, contiguous hole slot 23 places then are provided with a vertical profile groove 26;

This handle body 3, comprise the inside and outside lid 31,32 that connects barre, lid 31 inner edges are provided with vertical prominent rib 311 in this, when clamping ring 2 is inserted, nationality constitutes the location by this prominent rib 311 with setting of profile groove 26, and is provided with the fixed bar 321 of projection in this outer cover 32;

The shell fragment 4 of one curved arc shape, one end are provided with the sleeve part 41 of the bending of reeling, and make this sleeve part 41 be placed in first fixed leg 24 of clamping ring 2 hole slots 23, make its sheet body portion be resisted against second fixed leg 25;

Nationality is by the combination of aforementioned components, and this keeper 1 is fixed in the core position of lockset 6 with the fixing hole 14 of two symmetries wherein behind a stacked spring 5,32 of this outer cover with fixed bar 321 wear keeper 1 in addition the fixing hole 14 of two symmetries locked; After core wears axostylus axostyle 7 and spring 8, the interior lid 31 and the clamping ring 2 of handle body 3 are placed on the keeper 1, nationality is by the rotation of the interior lid 31 of handle body 1, make keeper 1 be sticked in the rank portion 22 of clamping ring 2, and nationality constitutes the location by the hook part 13 that shell fragment 4 is held in keeper 1, makes inside and outside lid 31,32 be fixed in lockset 6.Nationality to drive the core of lockset 6, constitutes opening and closing of lockset 6 by the rotation of the barre of inside and outside lid 31,32; Thereby the assembling that makes door lock handle is more convenient, have more attractive in appearance and have more safety.

Shown in accompanying drawing 4, accompanying drawing 5 and accompanying drawing 6, the utility model when assembling such as accompanying drawing 1, behind keeper 1 a stacked spring 5, be locked in the core position of lockset 6 with the fixing hole 14 of two symmetries wherein, 32 of this outer cover with fixed bar 321 wear keeper 1 in addition the fixing hole 14 of two symmetries fixed; After core wears axostylus axostyle 7 and spring 8, the interior lid 31 and the clamping ring 2 of handle body 3 are placed on the keeper 1, wherein, because the groove 21 formed circle footpaths of this clamping ring 2 are slightly larger than keeper 1, and the drift angle of keeper is made as arc sections 12, keeper 1 is inserted in along groove 21 with arc sections 12, and nationality is by the rotation of the interior lid 31 of its handle body 1 again, makes the arc sections 12 of keeper 1 be sticked in the rank portion 22 of clamping ring 2;

After the arc sections 12 of keeper 1 is sticked in the rank portion 22 of clamping ring 2, the interior lid 31 of this handle body 1 is rotated further, after the hook part 13 of keeper 1 goes to the position of shell fragment 4, nationality constitutes the location by the hook part 13 that shell fragment 4 is held in keeper 1, make inside and outside lid 31,32 be fixed in lockset 6, so, handle body 1 can't be disassembled by external force, and then makes the assembling of door lock handle more convenient, has more attractive in appearance and have more safety.
