[0011] Figure 2 It is a schematic diagram of the local structure of the bending part of the utility model. DETAILED DESCRIPTION

[0012] A telescopic tube for a mobile lighting device includes several outer support tubes 1 and inner support tubes 2 that are sleeved together. The outer support tube 1 is sleeved and fixed with a tightening clamp 3 at one end close to the inner support tube. Among the several outer support tubes 1 and inner support tubes 2 that are sleeved together, one of the outer support tubes 1 is slidingly sleeved with an auxiliary bending tube 4, and the inner end of the inner support tube 2 is rotatably connected to the outer end of the auxiliary bending tube 4. The outer end of the auxiliary bending tube 4 is provided with a U-shaped opening rotation groove 401, and the inner end of the inner support tube 2 is provided with a rotating tongue plate 201 that extends into the U-shaped opening rotation groove 401. Corresponding axial holes 303 are provided on the side plates on both sides of the U-shaped opening rotation groove 401 and on the rotating tongue plate 201. The bolt shaft 5 passes through the axial hole 303 to rotationally connect the auxiliary bending tube 4 and the inner support tube 2 together.

[0013] like Figure 1 and Figure 2 As shown, the lower end of the telescopic tube of the present invention is plugged and fixed on the mobile power supply, and a lamp holder 7 is fixed on the top of the telescopic tube. The lighting lamp is fixed on the lamp holder 7 and electrically connected to the mobile power supply at the bottom to achieve lighting. The telescopic length adjustment of the telescopic tube facilitates the adjustment of the height of the lamp holder 7, thereby achieving the purpose of adjusting the lighting height. During the adjustment process, when it is necessary to adjust the angle, just loosen the tightening clamp 3 and continue to pull the inner support tube 2 outward until the auxiliary bending tube 4 is pulled out. Then, the tightening clamp 3 can be locked. At this time, the inner support tube 2 can be rotated 90 degrees to both sides along the auxiliary bending tube 4 to achieve the purpose of adjusting the lighting angle. If the auxiliary bending tube 4 is not pulled out in the outer support tube 1, it is at a vertical angle, and the lighting angle adjustment of the upper and lower heights can be achieved. When the auxiliary bending tube 4 is pulled out, the inner support tube 2 can be rotated 90 degrees to one side, and then it is in a horizontal state. It can be extended to one side by a certain length to achieve lateral extension lighting, thereby achieving angle adjustment.

[0014] The end of the bolt shaft 5 is threadedly connected with a nut 6.

[0015] The tightening clamp 3 is a handle-type squeezing tightening clamp, and a squeezing protrusion 308 is raised on the inner side of the handle 309 of the handle-type squeezing tightening clamp. The tightening clamp 3 is the same as the existing technical design.

[0016] The inner support tube 2 is sleeved with a buffer rubber ring 8. By adding the buffer rubber ring 8, when the utility model is stored, collision between adjacent tightening clamps 3 is avoided, and hands are prevented from being pinched during squeezing, making it safer to use.
