Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Fig. 2 is the utility model exploded view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: refer to Fig. 1 and Fig. 2, a kind of metallic combination manual screw, comprise screw rod 2, hand-screw cover 1, spring 3 and fixed base 4, fixed base 4 tops and hand-screw cover 1 are connected to form shell, screw rod 2 and spring 3 are arranged in shell, described screw rod 2 has a head, this head periphery is angular structures 20 and is fixed on hand-screw and overlaps the rib shape anchor ring of 1 interior correspondence, spring 3 is enclosed within on screw rod 2 and presses on screw head, the spring the other end presses on the interior annular boss of fixed base 4, and described screw rod 2 stretches out capable flexible reset of fixed base bottom end opening under spring coordinates.Fixed base 4 open tops are provided with to be inverted and buckle 41, and it overlaps clasp corresponding to 1 inner side with hand-screw and is connected, and fixed base 4 bottoms are provided with ledge structure 42 for riveted support 5, and on fixed base 4, are provided with positioning ring 43.The head of screw rod 2 is linkage section and thread section below, and thread section diameter is greater than linkage section diameter.Hand-screw overlaps 1 week side and is provided with some axial raised lines.
The utility model screw principle is: lead screw portion adopts 8 corner angle modes to be fixed to hand-screw cover (hand-screw head) the inside, the effect that locks of turn hand-screw head, spring assembly is in lead screw portion and screw fixed base the inside, pressing hand-screw head makes lead screw portion by the spring reset of stretching, on fixed base, there is one to buckle that to adopt machining to be fixed on hand-screw cover inner simultaneously, can limit lead screw portion return stroke, fixed base head has design step, also adopts machining (riveted) to reach an entirety to support.
Compound mode of the present utility model is as follows:
1. to be encased in hand-screw cover by direction inner fixing for screw head
2. spring is packed on screw rod
3. fixed base is adopted the processing of mechanical riveted to buckle and be pressed in above-mentioned entirety, what on fixed base, buckle is used for controlling riveted retrolisthesis;
4. finally adopt machining (riveted) to support on the overall screw having assembled, be assembled into finished product.
Above record, only, for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
