[0026] A plurality of slots 61 are arranged at intervals along the circumferential direction on the outer peripheral surface of the pivot 6. Preferably, a plurality of slots 61 are arranged at equal intervals on the outer peripheral surface of the pivot 6.

[0027] The latch assembly includes a latch 71 and an elastic element 72. The latch 71 is selectively inserted into one of the slots 61 of the pivot 6 to lock the rotation position of the lamp holder 7. One end of the elastic element 72 is fixed, and the other end of the elastic element 72 abuts against the latch 71 to apply an elastic force to the latch 71 to keep the latch 71 in one of the slots 61. When the lamp holder 7 is rotated, the latch 71 overcomes the elastic force of the elastic element 71 and retracts to exit one of the slots 61. In this embodiment, the lamp holder 7 is provided with a groove 73, and the latch 71 and the elastic element 72 are arranged in the groove 73. The elastic element 72 is a spring. In the specific embodiment shown in the figure, a through hole 70 for the pivot 6 to pass through is provided near the tail of the lamp holder, and a convex column 74 is provided on the hole wall of the through hole 70, and the groove 73 is opened at the top of the convex column 74.

[0028] Please refer to Fig.11 Preferably, the depth of the slot 61a that positions the lamp head 7 in the vertical position is greater than the depths of the remaining slots.

[0029] The lamp holder 7 comprises a lamp holder body 7a and a fixing ring 7b, wherein the fixing ring 7b is sleeved on the top periphery of the lamp holder body 7a and is screwed to the lamp holder body 7b. Thus, the length of the lamp holder body 7a can be shortened, and the lamp holder body 7a is convenient to disassemble and assemble, and is convenient for maintenance and installation.

[0030] The lamp holder body 7 a includes a lamp holder body shell 75 , a light-transmitting sheet 76 , a reflective cup 77 , an LED circuit board 78 and a heat sink 79 .

[0031] The LED circuit board 78 is provided with an LED lamp bead 781. The heat sink 79, the LED circuit board 78 and the rear part of the reflective cup 77 are sequentially arranged in the lamp body housing 75 from the back to the front. The heat sink 79, the LED circuit board 78 and the reflective cup 77 are detachably connected together by a fastener 701 passing through the LED circuit board 78. The LED lamp bead 781 is located at the rear end opening of the reflective cup 77. The front end of the reflective cup 77 has a circle of flanges 771 protruding radially outward, and the rear end of the flange 771 abuts against the front end of the lamp body housing 75; the light-transmitting sheet 76 abuts against the front end of the flange 771.

[0032] An external thread 75a is provided on the outer peripheral surface of the top of the lamp holder body shell 75, and an internal thread 75b matching the external thread 75a is provided on the wall of the central through hole of the fixing ring 7b, and the front end peripheral edge of the central through hole of the fixing ring 7b has an inwardly protruding retaining ring portion 76b, which abuts against the front end surface of the light-transmitting sheet 76 to prevent the light-transmitting sheet 76 from falling out.

[0033] The lamp head 7 of the lithium-ion work lamp can be selectively and detachably connected to the support base 1 of the desk lamp assembly. When the lithium-ion work lamp is not connected to the desk lamp assembly, it is used as an ordinary lithium-ion work lamp to meet the needs of direct lighting. At this time, the lamp head 7 can be rotated according to the actual lighting needs so that the light of the lithium-ion work lamp is emitted from different directions. After the lithium-ion work lamp is connected to the desk lamp assembly, the whole becomes a desk lamp, and the light beam emitted by the lamp head 7 is diffused by the diffuser disc 4 of the desk lamp assembly to meet the needs of diffuse lighting.

[0034] Specifically, when the upper end of the lamp holder 7 (i.e., the upper end of the fixing ring 7b) is inserted into the annular gap 14 formed between the lower annular retaining ring 12 and the inner annular retaining ring 13 of the support seat 1, the connection between the lithium-ion work lamp 200 and the table lamp assembly 100 is achieved. Most of the time, the lamp holder 7 is connected to the support seat 1 only when the lamp holder 7 is rotated to a vertical position, so that the lithium-ion work lamp assembly can be used as a table lamp. Since the depth of the slot 61a in which the lamp holder 7 is positioned in the vertical position is greater than the depth of the other slots, not only is the locking of the vertical position more reliable, but the user can also obtain a different operating feel during the process of rotating the lamp holder 7. In a few cases, the lamp holder 7 can also be connected to the support seat 1 when the lamp holder is in a rotation position other than the vertical position, so that the lithium-ion work lamp assembly can be used as a table lamp.

[0035] After completing the connection between the lithium-ion work lamp 200 and the desk lamp assembly 100, turn on the power switch of the lithium-ion work lamp, the LED lamp bead 781 emits light, and the reflective cup 77 emits the light toward the top along the light direction, and the light is diffused to the surroundings through the spherical protrusion 42 of the diffuser disc, finally achieving the diffuse light desk lamp lighting effect.

[0036] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
