Abstract

A starting device including a housing, a circuit board disposed in the housing, an electromagnetic element, a lever structure and a pressing assembly. A recessed hole is formed on one side of the housing. The circuit board is connected to a power cable. The electromagnetic element is electrically connected to the circuit board. The electromagnetic element includes a coil and a plunger operated by magnetic attraction of the coil. One end of the lever structure is in contact with the plunger. The pressing assembly includes a button cover and a screw rod disposed in the recessed hole. One end of the screw rod is fixedly connected to the button cover, while the other end of the screw rod extends out of the other side of the housing. The screw rod is screwably connected to the other end of the lever structure.

Claims

1. A starting device, comprising:

a housing with an accommodation room formed therein and a recessed hole formed on one side thereof, said recessed hole communicating with said accommodation room;

a circuit board disposed in said accommodation room and connected to a power cable;

an electromagnetic element disposed in said accommodation room and electrically connected to said circuit board, said electromagnetic element comprising a coil capable of receiving electrical energy to generate a magnetic force and a plunger operated by magnetic attraction of said coil;

a lever structure pivotedly connected to an inner wall surface of said accommodation room, one end of said lever structure being in contact with said plunger; and

a pressing assembly comprising a button cover and a screw rod disposed in said recessed hole, one end of said screw being fixedly connected to said button cover, the other end of said screw rod extending out of the other side of said housing, said screw rod being screwably connected to the other end of said lever structure,

wherein said screw rod rotates with said button cover at said the other end of said lever structure to fine-tune the distance from said the other end of said screw rod to said the other side of said housing.

2. The starting device according to claim 1, wherein said housing comprises an upper case and a lower case combining with each other, said recessed hole is formed on a surface of said upper case, and said lower case comprises an opening that said the other end of said screw rod extends out of

3. The starting device according to claim 2, wherein said lower case comprises a plurality of side walls on an inner wall surface and a plurality of pivot holes formed on said plurality of side walls, and said lever structure comprises on both sides a plurality of shafts pivotedly connected to said plurality of pivot holes.

4. The starting device according to claim 3, wherein the distance from said shafts to said coil is larger than the distance from said shafts to said button cover.

5. The starting device according to claim 3, wherein said pressing assembly comprises a resilient element, one end of said resilient element being in contact with said button cover, while the other end of said resilient element being in contact with said the other end of said lever structure.

6. The starting device according to claim 5, wherein said button cover comprises a limiting slot, said resilient element being disposed in said limiting slot and socketedly connected to an outer portion of said screw rod.

7. The starting device according to claim 5, wherein said lever structure provides a hollow slot at said the other end, said pressing assembly comprises a screw fastener disposed in said hollow slot, and said screw rod is disposed at said the other end of said lever structure and screwably connected to said screw fastener.

8. The starting device according to claim 7, wherein said lever structure provides at said the other end a location hole that said screw rod extends out of, a screw hole of said screw fastener aligns with said location hole and is locked to said screw rod, and male screw threads of said screw rod are screwably connected to female screw threads of said screw fastener.

9. The starting device according to claim 2, wherein said lever structure comprises at said the other end a resilient body against said inner wall surface of said lower case.

10. The starting device according to claim 1, wherein a plurality of embossed patterns are formed on an outer surface of said button cover, and said plurality of embossed patterns are exposed outside said recessed hole.

11. The starting device according to claim 1, wherein said circuit board comprises a connecting port exposed outside said housing to receive external signal cables.
