When the LED lamp body 1 needs to be carried outdoors, the positioning screw 18 can be rotated in conjunction with the limit bearing 17 to screw the positioning screw 18 out of the first thread groove 6, so that the movable plate 10 and the extension plate 12 can be pulled out of the storage groove 9 to facilitate rotation with the rotating rod 14. After the extension plate 12 is rotated to a suitable angle, one end of the positioning screw 18 is screwed into the second thread groove 7, so that the support plate 8, the movable plate 10 and the extension plate 12 can be made into a "V" shape as a whole, and then the user can conveniently hold and carry the LED lamp body 1.

[0020] Example 2 On the basis of the first embodiment, in order to further improve the stability of the LED lamp body 1 when used outdoors, a support plate 8 is provided, the power storage module 3 is a common rechargeable battery, a photovoltaic panel 19 is provided on the side of the LED lamp body 1, the photovoltaic panel 19 is electrically connected to the power storage module 3, a positioning rod 20 is provided on the side of the placement groove 5, the support plate 8 is sleeved on the positioning rod 20, the support plate 8 is rotatably connected to the positioning rod 20, the support plate 8 is received in the placement groove 5, a limited opening 21 is provided on the side of the storage groove 9, and a fixing screw 22 is provided on the side of the movable plate 10. The fixed screw 22 passes through the limiting opening 21, and a fixing nut 23 is screwed on the surface of the fixed screw 22. The length of the long side of the limiting opening 21 is less than the length of the long side of the side of the storage slot 9. The first vertical plate 11 is sleeved on the rotating rod 14, and the first vertical plate 11 is rotatably connected to the rotating rod 14. A moving groove 24 is opened on the side of the movable plate 10, and a positioning pin 25 is inserted into the moving groove 24. The side of the positioning pin 25 has an "L"-shaped structure.

When the movable plate 10 is pulled to the appropriate position, the fixing nut 23 can be tightened to fix the movable plate 10, and then the base plate 16 can be conveniently rotated in conjunction with the hinge 15, so as to facilitate the use of the positioning screw 18 to insert into the ground, and the support of the support plate 8, the movable plate 10 and the extension plate 12 can be coordinated to increase the placement stability of the LED lamp body 1, which is convenient for outdoor use when the ground is uneven. In addition, the power storage module 3 can power the LED lamp body 1 when it is outdoors and the photovoltaic panel 19 can conveniently charge the power storage module 3, thereby increasing the outdoor use time of the LED lamp body 1.

[0021] In order to facilitate the rotation of the positioning screw 18, a limiting nut 27 is set. The positioning screw 18 is fixedly connected to the inner ring surface of the limiting bearing 17. The surface of the positioning screw 18 is fixedly connected to the limiting nut 27. The extension plate 12 and the movable plate 10 can be inserted into the storage groove 9. When the positioning screw 18 needs to be rotated, the limiting nut 27 can be rotated. When it is necessary to carry a larger LED lamp body 1, the positioning pin 25 can be pulled first to disengage one end of the positioning pin 25 from the fixing groove 26, so that the extension plate 12 and the movable plate 10 can be inserted into the storage groove 9. The extension plate 12 is rotated at an angle, and then the movable plate 10 is moved to a suitable position in the storage groove 9 and fixed, and one end of the positioning screw 18 can be screwed into the second threaded groove 7 for fixation, so that the support plate 8 and the movable plate 10 can form a "V"-shaped structure with the extension plate 12 and the bottom plate 16, so that it is convenient for the user to lift and carry the LED lamp body 1 more conveniently. One end of the positioning pin 25 is inserted into the fixing groove 26 to prevent the extension plate 12 from rotating, so that the extension plate 12 can be stored in the placement groove 5 later.

[0022] Example 3 On the basis of the second embodiment, an elastic ring 28 is provided for the convenience of protecting the lamp tube 2. An elastic ring 28 is provided on the outer surface of the lamp tube 2. A buffer groove 29 is provided on the side of the elastic ring 28. A corrugated rubber plate 30 is fixedly connected in the buffer groove 29. One end of the corrugated rubber plate 30 is fixedly connected to the upper surface of the buffer groove 29, and the other end of the corrugated rubber plate 30 is fixedly connected to the lower surface of the buffer groove 29. A positioning ring 31 is provided on the side of the buffer groove 29. There are two groups of positioning rings 31, and the two groups of positioning rings 31 are symmetrically distributed about the buffer groove 29. A rubber sealing ring 32 is provided in the buffer groove 29. A positioning groove 33 is provided on the side of the rubber sealing ring 32. The positioning ring 31 is inserted into the positioning groove 33. A drawing groove 34 is provided on the outer side of the rubber sealing ring 32. The drawing groove 34 is an "L"-shaped ring structure as a whole; When in use, when the LED lamp body 1 is tilted, the elastic ring 28 can first contact the ground. Then, the overall impact resistance of the elastic ring 28 can be increased by using the elastic ring 28 and the corrugated rubber plate 30 arranged in the buffer groove 29, so as to reduce the impact force received by the lamp barrel 2 and avoid damage to the bulb inside the lamp barrel 2. When the corrugated rubber plate 30 needs to be removed, it can be inserted into the pull groove 34 and directly pull out the rubber sealing ring 32, so that the positioning card slot 33 is separated from the positioning ring 31, and the rubber sealing ring 32 will lose the sealing of the buffer groove 29. The positioning card slot 33 and the positioning ring 31 can cooperate to conveniently fix the rubber sealing ring 32 in the buffer groove 29. The opening of the buffer groove 29 makes the internal cavity of the elastic ring 28, thereby also increasing the overall buffering effect of the elastic ring 28.

[0023] In order to facilitate the protection inside the lamp barrel 2, a protective net 37 is provided. Fixed threads 35 are provided on the inner side surface of the lamp barrel 2. A support ring 36 is screwed inside the fixed threads 35. A protective net 37 is provided on the inner side surface of the support ring 36. There are two groups of protective nets 37, and the two groups of protective nets 37 are respectively located at both ends of the support ring 36. A damping bearing 38 and a protective frame 39 are provided on the surface of one group of protective nets 37. The inner ring surface of the damping bearing 38 is fixedly connected with a rotating screw 40. The protective frame 39 is in an overall "匚"-shaped plate structure. The protective frame 39 is adhesively and fixedly connected to the surface of the protective net 37. The rotating screw 40 passes through the other group of protective nets 37. A magic tape plane 41 is provided on the outer side surface of the protective frame 39. A corrugated cover 42 is provided on the inner side surface of the protective frame 39. One end of the corrugated cover 42 is fixedly connected to the inner side surface of the protective frame 39. A sealing plate 43 is provided at the other end of the corrugated cover 42. A magic tape rough surface 44 is provided on the outer side surface of the sealing plate 43. The sealing plate 43 is in an overall square plate structure. One end of the sealing plate 43 is fixedly connected to the surface of the rotating screw 40. The corrugated cover 42 is stored in the protective frame 39; When in use, first, the protective net 37 can prevent the bulb inside the lamp barrel 2 from being knocked when used outdoors, and also avoid the inconvenience of using the LED lamp body 1 outdoors after the traditional glass cover is knocked and broken. When not in use, it can prevent larger particulate impurities from entering the lamp barrel 2. First, the rotating screw 40 can be rotated in cooperation with the damping bearing 38, so as to drive the sealing plate 43 to rotate. By rotating the sealing plate 43, the corrugated cover 42 can be pulled and unfolded. When rotated to the appropriate position, the adhesion of the magic tape rough surface 44 and the magic tape plane 41 can be used for fixation. Thus, the lamp barrel 2 can be covered and protected by the unfolded corrugated cover 42. The setting of the two groups of protective nets 37 increases the protection on the one hand and also avoids the problem that the unfolded corrugated cover 42 warps on the other hand.

[0024] In actual use, the LED lamp body 1 can be used in conjunction with the lamp tube 2 for lighting. When the LED lamp body 1 needs to be carried outdoors, the positioning screw 18 can be rotated in conjunction with the limit bearing 17 to screw the positioning screw 18 out of the first thread groove 6, so that the movable plate 10 and the extension plate 12 can be pulled out of the storage groove 9 to facilitate the rotation of the rotating rod 14. After the extension plate 12 is rotated to a suitable angle, one end of the positioning screw 18 is screwed into the second thread groove 7, so that the support plate 8, the movable plate 10 and the extension plate 12 are formed into a "V" shape as a whole. Then, the user can hold the LED lamp body 1 for carrying. In addition, when the LED lamp body 1 is released, When the lamp falls over, the elastic ring 28 can first touch the ground, and then the elastic ring 28 and the corrugated rubber plate 30 set in the buffer groove 29 can be used to increase the overall impact resistance of the elastic ring 28, thereby reducing the impact force on the lamp tube 2 and avoiding damage to the bulb inside the lamp tube 2. When the corrugated rubber plate 30 needs to be removed, it can be inserted into the pull groove 34 to directly pull out the rubber sealing ring 32, so that the positioning card groove 33 is separated from the positioning ring 31, so that the rubber sealing ring 32 loses its seal on the buffer groove 29. The positioning card groove 33 cooperates with the positioning ring 31 to facilitate the fixing of the rubber sealing ring 32 in the buffer groove 29. The opening of the buffer groove 29 creates a cavity inside the elastic ring 28, thereby also increasing the overall buffering effect of the elastic ring 28.
