DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(7) FIG. 1 shows a structural view of a working light provided by a preferred embodiment of the present invention. In the present embodiment, the working light includes a base 1, an illumination member 2 and a switch control 5, a battery supplying power to the illumination member 2 is arranged inside the base 1, the base 1 is connected to the illumination member 2 by the deformable serpentine hose 4, the base 1 and the illumination member 2 have the same connection structure for connecting to said serpentine hose 4. FIG. 2 shows a connection structure of the base and the illumination member. In the present embodiment, the base 1 is connected to a first end thread of the serpentine hose 4, the illumination member 2 is connected to a second end thread of the serpentine hose 4, the first end thread and the second end thread are both internal threads, the base 1 has a corresponding external thread at the connection end between the base and the serpentine hose, the illumination member 2 has a corresponding external thread at the connection end between the illumination member and the serpentine hose. The illumination member and the base of the illumination light have the same connection structure 61 and 62, the base is not able to be connected to the illumination member directly, and users would not make mounting errors in use.

(8) The base has an annular electrode slice at the connection end between it and the serpentine hose, an electrode connecting to the annular electrode slice of the base is arranged at the first end of the serpentine hose connecting to the base; the second end of the serpentine hose has the annular electrode slice, the illumination member has an electrode connecting to the annular electrode slice of the serpentine hose at the connection end between it and the serpentine hose. In order to gain better conductivity, the electrodes of the serpentine hose and the illumination member are both elastic poles.

(9) As shown in FIG. 4 and FIG. 5, the deformable serpentine hose includes a corrugated pipe 41, a star-shaped pipe 42 and a flexible metal wire 43, the star-shaped pipe 42 and the flexible metal wire 43 are arranged inside the corrugated pipe 41, the outer edge of the star-shaped pipe 42 is located at the maximum inner diameter of the corrugated pipe 41, the space between adjacent star structures of the star-shaped pipe 42 corresponds to the space between adjacent maximum portions of inner diameter of the corrugated pipe 41. FIG. 4 shows a sectional view of the star structure. The cooperation between the star-shaped pipe and the corrugated pipe is tight, which can effectively improve the hardness of the serpentine hose. The flexible metal wire 43 transfers current for the illumination member 2.

(10) Said deformable serpentine hose further includes an iron wire 44, the iron wire 44 is arranged in the center of the star-shaped pipe 42 and passes through the star-shaped pipe 42. The iron wire enhances supporting effect of the serpentine hose further.

(11) One end of the serpentine hose has a groove, the other end has a raised line corresponding to said groove, the raised line is inserted into the groove to connect the two ends of the serpentine hose together, which reduces the space occupied by the serpentine hose, making it easier to carry and place.

(12) In the working light of the present invention, the base and the illumination member is able to be connected by a joint-sleeve.

(13) FIG. 3 shows a structural view of a working light with the joint-sleeve provided by a preferred embodiment of the present invention. The base 1 is connected to the illumination member 2 by the joint-sleeve 3. The base 1 is connected to a first end thread of the joint-sleeve 3; the illumination member 2 is connected to a second end thread of the joint-sleeve 3. The first end and the second end threads of the joint-sleeve 3 are both internal threads. The base 1 has an external thread corresponding to the first end of the joint-sleeve 3 at the connection end between the base and the serpentine hose. The illumination member 2 has an external thread corresponding to the second end of the joint-sleeve 3 at the connection end between the illumination member and the serpentine hose. Since the insulating joint-sleeve is replaceably used for connecting the base to the illumination light, the structure is more compact and easy to carry.

(14) The illumination member 2 includes a lamp cap 21 and a lamp cap holder 22, the lamp cap holder 22 is connected to the joint-sleeve 3 to receive power from the base and provide power to the lamp cap 21, and the lamp cap 21 is pivotably connected to one end 221 of the lamp cap holder 22. Since the lamp cap 21 is able to pivot relatively around the lamp cap holder 22, the multi-angle illumination of the lamp cap is achieved, and users only need to change the angle of the light cap to adjust the lighting effects.

(15) FIG. 6 shows a partial enlarged view of a lamp cap provided by a preferred embodiment of the present invention. The lamp cap 21 has protuberances 7, one end 221 of the lamp cap holder has a surface cooperating with the protuberances, and the lamp cap 21 overcomes friction between said protuberances and said surface when pivoting. The protuberances and the cooperating surface are arranged on the lamp cap and on the connection end of the lamp cap holder, which increases the friction between the lamp cap and the connection end of the lamp cap holder. After the angle of the lamp cap is determined, under the action of friction, the angle of the lamp cap is easy to maintain, and not easy to change. In a preferred embodiment of the present invention, when the protuberances of the lamp cap 21 cooperate with the surface of the lamp cap holder 22, said protuberances hide inside the lamp cap holder 22 throughout. It can effectively prevent dust or dirt to be accumulated on the protuberances which may affect pivoting of the lamp cap.

(16) The angle between the lamp cap 21 and said end 221 of the lamp cap holder can be controlled within 0 to 90.

(17) The number of the protuberances on the lamp cap 21 is 3 to 10. The multi-angle adjustment of the lamp cap can be achieved by arranging the location, number, and distance of the protuberances.

(18) A high-power LED lamp and a lens are arranged inside the lamp cap 21, the light ray of the LED lamp is emitted through said lens, the lens is arranged so that the distance between it and said LED lamp is adjustable. By changing the distance between the lens and the LED lamp, a switch between far light (e.g. as a flashlight) and close light (e.g. as a working light) can be achieved, which satisfies the needs of users under different conditions.

(19) In a preferred embodiment of the present invention, the shell of the lamp cap 21 is made of transparent material. By this arrangement, the working light increases the illuminating brightness and is usable as a camping light.

(20) The foregoing describes the preferred embodiments of the present invention. It should be understood that one of ordinary skill in the art can make many modifications and changes according to the concept of the present invention without creative work. Therefore, any technical solutions obtained by a person skilled in the art depending on this technical concept according to this invention on the basis of the prior art through logical analysis, reasoning or limited experimentation, should fall in the protection scope determined by the claims.
