The present invention is to provide a clamp lamp comprising a first side plate, a second side plate and a lateral plate, wherein the lateral plate connects the first side plate and the second side plate, thereby forming a retaining space between the first side plate and the second side plate. A lamp is disposed on the first side plate opposite to the second side plate and powered by at least a battery installed in a battery holder formed on the clamp. A light source can thus be generated from a light emitting portion of the lamp. A screw rod is disposed on the second side plate and connected with a mobile portion. By adjusting the amount of the screw rod inserted into the retaining space, the clamp can firmly grab an object, so as to securely fasten the lamp onto the object.
1. A clamp lamp comprising;
a clamp having a retaining space formed thereon for inserting an object therein, a first side plate and a second side plate;
a lamp that is disposed on one side of the clamp, the lamp comprising a light emitting portion;
a screw rod being movably disposed on another side of the clamp, one end of the screw rod being inserted into the retaining space, whereby the screw rod can move back and forth in the retaining space, and whereby one end of the screw rod can move towards the side of the clamp with the lamp disposed thereon or another side of the clamp;
a mobile portion is formed on one end of the screw rod facing the retaining space, so as to move the mobile portion following the movement of the screw rod;
a first spacer is formed on the mobile portion facing the first side plate, and a second spacer is formed on the first side plate facing the second side plate; and
wherein a first dovetail groove and a second dovetail groove are respectively formed on the central portion of the first spacer and the second spacer, and a first protrusive portion and a second protrusive portion are respectively disposed into the first dovetail groove and the second dovetail groove.
2. The clamp lamp as recited in claim 1 , wherein the clamp further comprises:
a lateral plate including a pair of opposite rims, wherein the opposite rims of the lateral plate are respectively connected to the first side plate and the second plate, thereby forming the retaining space between the first side plate and the second side plate, and wherein an opening is formed between the first side plate and the second side plate opposite to the lateral plate.
3. The clamp lamp as recited in claim 2 , wherein the lamp, the battery holder and a power switch are formed on the first side plate not facing the second side plate, and wherein the lamp further comprises:
a lamp cover covering the light emitting portion for focusing the light source generated from the light emitting portion;
an extension tube, one end of the extension tube connecting the light emitting portion and the other end of the extension tube coupling with the battery holder; wherein
the battery holder comprising a battery cover that is detachable from the clamp for installing at least a battery therein and shielding the battery; and wherein
the power switch controls the electrical power of the battery to be conducted to the light emitting portion through the extension tube.
4. The clamp lamp as recited in claim 3 , wherein the extension tube is bent on the clamp.
5. The clamp lamp as recited in claim 2 , wherein a screw hole is formed on the second side plate for inserting one part of the screw rod into the retaining space therethrough.
6. The clamp lamp as recited in claim 1 , wherein an actuating portion is formed on one end of the screw rod obtruding out of the clamp.
7. The clamp lamp as recited in claim 1 , wherein the surface of the first spacer and the second spacer facing with each other is a flat surface.
8. The clamp lamp as recited in claim 1 , wherein the surface of the first spacer and the second spacer facing with each other is an undulated surface.
9. The clamp lamp as recited in claim 1 , wherein the surface of the first spacer and the second spacer facing with each other is a saw-toothed surface.
10. The clamp lamp as recited in claim 1 , wherein a first concave portion and a second concave portion are respectively formed on the first spacer and the second spacer corresponding respectively to the locations of the first dovetail groove and the second dovetail groove.
11. The clamp lamp as recited in claim 10 , wherein the surface of the first concave portion and the second concave portion facing with each other is a flat surface.
12. The clamp lamp as recited in claim 10 , wherein the surface of the first concave portion and the second concave portion facing with each other is a saw-toothed surface.
13. The clamp lamp as recited in claim 10 , wherein the surface of the first concave portion and the second concave portion facing with each other is an undulated surface.
