Rotary knob switch lamp holder

A rotary knob switch lamp holder, comprising:

• a main casing, a covering plate, a cathode power connecting plate, an anode power connecting plate, a first conducting plate, a second conducting plate, a rotary knob mechanism and a threaded collar, wherein a pair of erected hooks are defined upright inside a top surface of the main casing, an assisting hook is respectively formed on the front edges of the bottoms of the hooks, a stopping edge is configured on the top surface of the main casing corresponding to the fronts of the hooks, an inserting slot is provided near a side of each hook, a bottom edge of the main casing is upward to form a through slot communicating with the outside, the bottom surface of the main casing is inward to form a big housing slot located in a center and two side housing slots located on the left and right sides, the through slot passes through one of the side housing slots and further communicates with the big housing slot and the bottom surface of the main casing is inward to form a pair of engaging slots;
• a central through hole is provided on the covering plate and a through slot is respectively configured on the front and back sides thereof, wherein an engaging hole and a penetrating hole are respectively configured on the two sides of the central through hole;
• the cathode power connecting plate from top to bottom is provided with a clamping section, the front end is concaved to form a concave contacting slot, the rear end is bent downward to upright form a base section, the bottom end of the base section is further bent to form a connecting section with an engaging hole on the end;
• the anode power connecting plate from top to bottom is provided with a clamping section with a concave contacting slot on the front end, the rear end is bent downward to upright form a resisting plate and the center of the resisting plate is punched to form a backward inclining first guided connecting plate;
• the first conducting plate from top to bottom is provided with a frontward inclining second guided connecting plate, a rear end is formed to be a resisting plate and then moves forward for a section to further move downward to upright form a guided touching plate;
• the second conducting plate is a conductive material and a third guided connecting plate is defined from top to bottom, a rear end is bent forward for a section and then resists backward to form a resisting plate with a connecting hole, and then, the rear end of the resisting plate is inclined downward to form a guided touching plate;
• the rotary knob mechanism comprises a rotary rod, an insulated rotor and a rotor conducting plate, an end of the rotary rod is inserted into a center of the insulated rotor to be secured, the rotor conducting plate is enclosed to form a housing space from a wall body and a bent outer wall, the outer wall is divided into a first contacting plate, second contacting plate, third contacting plate and an empty part, sequentially arranged in a form of a ratchet, the insulated rotor fits into the housing space of the rotor conducting plate to form a combined status, an outer wall of the insulated rotor is distributed in the form of a ratchet, sequentially forming a first ratchet, a second ratchet, a third ratchet and a fourth ratchet;
• the threaded collar is a conductive material, a ring wall is configured with a threaded circle, an open slot is configured on a top surface and a connecting hole is respectively configured on the two sides of the open slot;
• and
• while assembly, the clamping section and the base section of the cathode power connecting plate is penetrated and fitted into one of the side housing slots of the main casing, thereby enabling the concave contacting slot of the clamping section to be positioned inside one of the inserting slots, and then, the anode power connecting plate is placed in from one side of the big housing slot, thereby enabling the resisting plate of the anode power connecting plate to be inserted into the thin slot inside the big housing slot and the concave contacting slot of the clamping section to be positioned inside the other inserting slot, and the first guided connecting plate of the anode power connecting plate is rested inside the big housing slot, and further the first conducting plate is placed in from the other side of the big housing slot, thereby enabling the resisting plate of the first conducting plate to be inserted into the thin slot inside the big housing slot and the second guided connecting plate of the first conducting plate to be rested inside the big housing slot, and further, the rotary knob mechanism is placed in the big housing slot, the side housing slot and the through slot, and the part of the rotor conducting plate enclosing the insulated rotor enters into the space enclosed by the first guided connecting plate and the second guided connecting plate, and then, the guided touching plate of the second conducting plate is placed in from one of the through slots of the covering plate and further a connecting piece passes through the engaging hole and the central through hole to be secured, and then, the covering plate covers the main casing to enable the third guided connecting plate to surround the rotor conducting plate, and then, the screw holder is provided on the bottom of the covering plate, thereby enabling the central through hole and through slot of the covering plate to enter into the open slot, and meanwhile the two connecting holes are aligned one by one to the engaging slots of the covering plate, and a connecting piece passes through the connecting hole and the engaging slot to be secured.
