At the same time, since the lighting seat 16 is rotatably connected to the mounting block 15, the irradiation direction of the light strip 17 can be adjusted by rotating the lighting seat 16, thereby further expanding the adjustment of the light irradiation range. When the user rotates the lighting seat 16 to a specified position, the fixing component 2 is used to fix the position of the lighting seat 16. In addition, the user can also adjust the length of the second support rod 12 extending out of the first support rod 11, thereby adjusting the working height of the mounting seat 13, and then adjusting the irradiation area of ​​the light strip 17 on the lighting seat 16.

[0030] like Figures 1 to 8As shown, the adjustment component 3 includes a turbine 31 and a worm 32. The turbine 31 is fixedly mounted on the mounting block 15. A rotating shaft 33 is coaxially mounted on the turbine 31. Both ends of the rotating shaft 33 are rotatably mounted on the mounting seat 13.

During the rotation of the second connecting shaft 35 The first connecting shaft 34 will be driven to rotate, and the rotation of the first connecting shaft 34 will drive the worm 32 to rotate, and the rotation of the worm 32 will drive the turbine 31 to rotate, and the rotation of the turbine 31 will drive the mounting block 15 and the lighting seat 16 to rotate, so that the angle between the lighting seat 16 and the second support rod 12 becomes larger, thereby expanding the illumination range of the light source, so that the user can adjust the illumination range of the light source by adjusting the angle between the lighting seat 16 and the second support rod 12 as needed. At the same time, when the user does not need to use the desk lamp for a long time, the driving ring 38 is rotated to move the lighting seat 16 toward the second support rod 12, so that the user can adjust the illumination range of the light source. The table lamp can be stored and the occurrence of dust sticking to the lamp strip 17 can be reduced; in addition, when in use, the user can make the second support rod 12 extend from the inside of the first support rod 11 or retract into the inside of the first support rod 11 along the vertical direction. At this time, the first connecting shaft 34 installed in the second support rod 12 will synchronously extend from the inside of the second connecting shaft 35 or retract into the inside of the second connecting shaft 35. In order to enable the second connecting shaft 35 to continue to drive the first connecting shaft 34 to rotate, when the user adjusts the position of the second support rod 12 and the first connecting shaft 34, the first connecting shaft 34 can be fixed on the second connecting shaft 35 through the limit assembly 4.

[0031] like Figures 1 to 8As shown, the limiting assembly 4 includes a latch 41, a fixing ring 42 and a second spring 43. The latch 41 is slidably installed on the top of the second connecting shaft 35 along the radial direction of the second connecting shaft 35. A plurality of through holes 44 are evenly opened on the first connecting shaft 34 along its length direction. One end of the latch 41 is inserted into the inside of the through hole 44. The fixing ring 42 is fixedly installed on the top of the second connecting shaft 35. One end of the second spring 43 is connected to the inner wall of the fixing ring 42, and the other end is connected to the latch 41. The interior of the first connecting shaft 34 is hollow, and an abutment rod 45 is installed inside the first connecting shaft 34 along its length direction. Two slide rails 46 are installed in parallel with each other inside the first connecting shaft 34. Both ends of the abutment rod 45 are slidably installed on the two slide rails 46 respectively. The abutment rod 45 is evenly fixedly installed along its length direction. There are a plurality of abutment blocks 47, which correspond to the plurality of through holes 44 one by one. The abutment blocks 47 are slidably inserted in the interior of the through holes 44. A rack 48 is fixedly installed on the top of the abutment rod 45. A support seat 461 is installed on the top of the slide rail 46. A mounting shaft 462 is rotatably installed on the support seat 461. A gear 463 is coaxially installed on the mounting shaft 462. The gear 463 is meshed with the rack 48. A first bevel gear 464 is coaxially installed on the end of the mounting shaft 462 away from the gear 463. A driving shaft 465 is rotatably installed on the first connecting rod. A second bevel gear 466 is coaxially installed on the driving shaft 465. The first bevel gear 464 is meshed with the second bevel gear 466. The other end of the driving shaft 465 extends to the outside of the first connecting rod. A driving assembly 5 for driving the driving shaft 465 to rotate is installed on the first connecting rod.When the user needs to adjust the position of the second support rod 12 and the first connecting shaft 34, the driving assembly 5 is used to drive the driving shaft 465 to rotate. During the rotation of the driving shaft 465, the second bevel gear 466 will be driven to rotate. During the rotation of the second bevel gear 466, the first bevel gear 464 will be driven to rotate. During the rotation of the first bevel gear 464, the gear 463 will be driven to rotate. During the rotation of the gear 463, the rack 48 will be driven to move, thereby driving the abutment rod 45 to move along the length direction of the slide rail 46. During the movement of the abutment rod 45, multiple abutment blocks 47 on the abutment rod 45 will be simultaneously inserted into multiple through holes 44 on the first connecting shaft 34, thereby pushing the pin 41 out of the through hole 44, and the second spring 43 will be compressed, with a tendency to restore to its original length. At this time, use After the user holds the second support rod 12 and moves it in the vertical direction, the length of the first connecting shaft 34 extending from the second connecting shaft 35 can be easily adjusted. Since the second support rod 12 is equipped with a collar 36, the length of the second support rod 12 extending from the first support rod 11 can be adjusted at the same time. When the second support rod 12 and the first connecting shaft 34 are adjusted to a suitable position, the user drives the driving shaft 465 to rotate in the reverse direction through the driving assembly 5, so that the abutting rod 45 moves toward a position away from the through hole 44. At this time, under the action of the second spring 43, the latch 41 will be inserted into the through hole 44 corresponding to the current position on the first connecting shaft 34, thereby fixing the first connecting shaft 34 on the second connecting shaft 35, so as to facilitate the synchronous rotation of the first connecting shaft 34 when the second connecting shaft 35 is rotated. ;

[0032] like Figures 1 to 8As shown, the driving assembly 5 includes a driving seat 51, which is fixedly mounted on the mounting seat 13, and a driving shaft 465 is inserted into the driving seat 51. A cross-shaped limit block 52 is installed on the end of the driving shaft 465 away from the second bevel gear 466, and a cylindrical driving block 53 is slidably sleeved on the driving shaft 465. A plurality of anti-skid edges 54 are evenly installed on the driving block 53 along its circumference. A placement groove 55 for installing the driving block 53 is provided on the driving seat 51, and an auxiliary rod 56 for facilitating its rotation is installed on the driving block 53; when the user needs to drive the driving shaft 465 to rotate through the driving assembly 5, the user holds the driving block 53 with his fingers and slides the driving block 53 along the length direction of the driving shaft 465 to make the driving block 53 rotate. 3 is away from the placement groove 55. At this time, the driving block 53 is rotated, and the anti-skid edge 54 can increase the friction between the finger and the finger. When the driving block 53 is rotated, under the action of the limit block 52, the driving block 53 will drive the driving shaft 465 to rotate synchronously. When the driving shaft 465 needs to be fixed, the user slides the driving block 53 along the driving shaft 465 and inserts the driving block 53 into the placement groove 55. The placement groove 55 has a plurality of tiny grooves matching the anti-skid edge 54, so as to fix the driving block 53. At the same time, since the driving block 53 is slidably sleeved on the driving shaft 465, the driving shaft 465 has a cross-shaped limit block 52, so as to fix the driving shaft 465, and the auxiliary rod 56 can make it more convenient for the user to hold the driving block 53.

A plurality of positioning holes 25 are evenly provided on the mounting seat 13. One end of the positioning pin 21 away from the limiting groove 23 is inserted into the positioning hole 25. When it is necessary to adjust the rotation angle between the lighting seat 16 and the mounting block 15, the user can adjust the rotation angle by hand. The finger is placed on the sliding sheet 24, and the friction between the finger and the sliding sheet 24 drives the sliding sheet 24 to move along the length direction of the limiting groove 23. During the movement of the sliding sheet 24, the positioning pin 21 will be driven to move, and the positioning pin 21 will move in the direction away from the positioning hole 25. At the same time, the first spring 22 will be compressed. At this time, the user can rotate the lighting seat 16. When the user rotates the lighting seat 16 to a suitable position, the user releases the sliding sheet 24. Under the elastic action of the first spring 22, the first spring 22 will push the positioning pin 21 to insert into the positioning hole 25 corresponding to the current position, thereby fixing the current rotation angle of the lighting seat 16.

[0034] like Figures 1 to 8As shown, a receiving groove 6 is provided inside the lighting seat 16, and an auxiliary lighting seat 61 is slidably installed in the receiving groove 6.

A third bevel gear 63 is coaxially installed at one end of the screw rod 62 close to the mounting block 15. A third connecting shaft 64 is rotatably installed at one end of the lighting seat 16 close to the mounting block 15. A fourth bevel gear 65 is coaxially installed on the third connecting shaft 64. The fourth bevel gear 65 is meshed with the third bevel gear 63. One end of the third connecting shaft 64 away from the fourth bevel gear 65 extends to the outside of the lighting seat 16, and a driving disk 66 is coaxially installed on the third connecting shaft 64. A handle 67 is installed on the driving disk 66. By installing and setting the auxiliary lighting seat 61, the auxiliary lighting seat 61 A light strip 17 is also installed at the bottom. The user can increase the length of the light strip 17 by controlling the length of the auxiliary lighting seat 61 extending out of the lighting seat 16. The light strip 17 has multiple LED lamp beads, which increases the illumination range of the light. When in use, the user holds the handle 67 and then turns it. The rotation of the handle 67 will drive the third connecting shaft 64 to rotate, and the rotation of the third connecting shaft 64 will drive the fourth bevel gear 65 to rotate. The rotation of the fourth bevel gear 65 will drive the third bevel gear 63 to rotate synchronously. The rotation of the third bevel gear 63 will drive the screw rod 62 to rotate synchronously. The rotation of the screw rod 62 will drive the auxiliary lighting seat 61 to move along the length direction of the storage slot 6, thereby adjusting the length of the auxiliary lighting seat 61 extending out of the lighting seat 16.

[0035] like Figures 1 to 8 As shown, the handle 67 is slidably installed on the driving disk 66, and a plurality of limiting holes 68 are evenly opened on the side wall of the lighting seat 16 with the rotating shaft 33 as the center. A baffle 69 is fixed on the end of the handle 67 close to the lighting seat 16, and the handle 67 is threadedly connected with the limiting hole 68; when the user moves the auxiliary lighting seat 61 to a suitable position, in order to improve the stability of the auxiliary lighting seat 61 during operation, the user needs to fix the position of the third connecting shaft 64. The user aligns the current handle 67 with the limiting hole 68 corresponding to the current position, and then twists the handle 67 so that the bottom of the handle 67 is threadedly connected with the limiting hole 68, so that the driving disk 66 can no longer rotate. When it is necessary to readjust the position of the auxiliary lighting seat 61, the user twists the handle 67 to separate the handle 67 from the limiting hole 68, and slides the handle 67 toward a position away from the limiting hole 68, so that it is convenient for the user to drive the driving disk 66 and the third connecting shaft 64 to rotate through the handle 67, and the baffle 69 can prevent the operator from pulling the handle 67 out of the driving disk 66.

[0036] like Figures 1 to 8As shown, electrode sheets 7 are fixedly installed on both side walls of the storage groove 6, a brush 71 is installed on one end of the auxiliary lighting seat 61 close to the mounting seat 13, the brush 71 is slidably connected to the electrode sheet 7, a fixing sheet 72 is installed on the auxiliary lighting seat 61, an abutment spring 73 is installed on the fixing sheet 72, the other end of the abutment spring 73 is connected to the brush 71, the other end of the brush 71 is electrically connected to the light strip 17 on the auxiliary lighting seat 61, and the electrode sheet 7 is electrically connected to the wire inside the lighting seat 16; compared with the situation where the auxiliary lighting seat 61 is directly connected to the auxiliary lighting seat 61 through the wire, since the auxiliary lighting seat 61 will repeatedly slide along the length direction of the storage groove 6, the repeated folding of the wire may cause the insulation layer of the wire to be damaged or the conductive wire inside the wire to break. In this embodiment, by adopting the connection method of the brush 71 and the electrode sheet 7, the connection is more stable and the service life is longer.

[0039] The implementation principle of this embodiment is: when in use, the user can use the adjustment component 3 to adjust the angle between the lighting seat 16 and the second support rod 12, so as to adjust the light irradiation angle of the light strip 17 on the lighting seat 16. At the same time, since the lighting seat 16 is rotatably connected to the mounting block 15, the irradiation direction of the light strip 17 can be adjusted by rotating the lighting seat 16, thereby further expanding the adjustment of the light irradiation range. When the user rotates the lighting seat 16 to the specified position, the fixing component 2 is used to fix the position of the lighting seat 16. In addition, the user can also adjust the length of the second support rod 12 extending out of the first support rod 11, thereby adjusting the working height of the mounting seat 13, and then adjusting the irradiation area of ​​the light strip 17 on the lighting seat 16.
