[0028] An angle is provided between adjacent bulb groups. The arc surface of the lamp shade 7 cooperating with any one of the bulb groups is π / 6 to π / 3.

[0029] In the present invention, it is composed of a housing 1, a lighting device, a first mounting bracket 2, and a second mounting bracket 3. The housing 1 is provided with a cavity. The lighting device is disposed at the cavity. The lighting device is fixed at the cavity through a rotating device disposed within the housing 1. The lighting device includes a housing 1, a lamp shade 7, and a bulb group 8 disposed within the lamp shade 7. The housing 1 is configured as a horizontally placed cylindrical tube type. A partial lamp shade 7 is provided on the upper end surface of the housing 1. The interior of the lamp shade 7 is provided with three triangular cavities separated by a central axis. A row of bulbs is respectively provided within the cavities. The angles of the three triangular cavities are all 30 degrees. When the light source in the middle cavity shoots horizontally, the light source in the upper cavity shoots upward at 30 degrees, and the light source in the lower cavity shoots downward at 30 degrees. In this way, three different angles of light can be formed. A rotary shaft 4 is horizontally provided through the central axis of the cylindrical lamp shade 7. The lamp shade 7 is rotated by rotating and adjusting the rotary shaft 4, further adjusting the light sources at three different angles, so that the light source can be better adjusted to the position where one is working for better illumination.

[0030] The rotation control member includes a drive shaft 9 disposed within the housing 1 and perpendicular to the rotary shaft 4, a second gear 10 sleeved on one end of the drive shaft 9 and meshing with the first gear 5 for rotation, a rotary knob 11 sleeved on the other end of the drive shaft 9, and a positioning rod 12 horizontally penetrating and fixed to the drive shaft 9 and cooperating with the interior of the rotary knob 11. The housing 1 is provided with an opening in cooperation with the rotary knob 11.

[0031] In the present invention, the rotary knob is separately provided from the drive shaft. A bearing for fixing the drive shaft is provided inside the housing, and the rotary knob is arranged to be movable up and down. The gear of the first gear 5 is provided at a certain angle, and the second gear 10 is arranged to be cooperatively provided at the lower end of the first gear 5. The rotary knob 11 penetrates through the opening. A cylindrical cavity is provided inside the rotary knob 11, so that the drive shaft 9 can be inserted into the cylindrical cavity. In order to enable the rotary knob 11 to drive the drive shaft 9 to rotate, two groove rails extend outwards from both ends of the cylindrical cavity to both sides. A positioning rod 12 is fixedly arranged horizontally through the drive shaft 9, and both ends of the positioning rod 12 are respectively arranged in the corresponding groove rails. In this way, the rotation of the rotary knob 11 can drive the rotation of the positioning rod 12, and the rotation of the positioning rod 12 can drive the rotation of the drive shaft 9. The rotation of the drive shaft 9 drives the rotation of the first gear 5, thereby achieving the effect of manually adjusting the lighting device.

[0032] A boss 13 is provided on the side of the rotary knob 11 located inside the housing 1. A limiting block 14 is symmetrically arranged at the lower end of the boss 13 with the rotation axis 4 as the center of symmetry. A groove 15 for cooperating with any one of the limiting blocks 14 is provided inside the housing 1.

[0033] A return spring 16 is provided between the upper end of the boss 13 and the housing 1.

[0034] In the present invention, the cooperative setting of the boss 13 and the groove 15 can achieve two states of the rotary knob 11. One is the non-adjustment state. Due to the return spring 16, the boss 13 is pressed into the groove 15 to achieve fixation, so that the lighting device is in a locked state. The other is the adjustment state. The rotary knob 11 is pulled outwards so that the boss 13 disengages from the groove 15. At this time, the rotary knob 11 can be rotated to adjust the light of the lighting device to an accurate position.

[0035] In the present invention, a plurality of grooves 15 are arranged around the drive shaft 9, and two boss 13 are symmetrically arranged. In this way, the two boss 13 can be symmetrically inserted into the symmetric grooves 15. The number of grooves 15 is set according to personal needs. In this way, the rotation angle of the rotary knob 11 is controlled according to the number of grooves 15.

[0036] A switching power supply 17 and a power display panel 18 for connecting the controller are respectively provided on the lower end surface of the housing 1.

[0037] In the present invention, the switching power supply 17 is a push-button. When the light bulb is off, by pressing the button once, an on signal can be transmitted to the controller. The controller transmits the on signal to the battery unit, and the battery unit transmits voltage to the lighting device, causing the light bulb in the lighting device to light up. When the light bulb is on, by pressing the button once, a close signal is transmitted to the controller. The controller transmits the close signal to the battery unit, and the battery unit stops supplying voltage to the lighting device, causing the light bulb in the lighting device to stop shining. The power display panel 18 includes two display lights provided on one side of the switching power supply 17. One is a display light marked 100%, and the other is a display light marked 0%. When the battery unit is charged to 100%, the controller sends an on signal to the 100% display light. When the battery unit cannot provide voltage to the lighting device, the controller will send an on signal to the 0% display light, thereby reminding the user of a fully charged battery unit and a battery unit with no power, so that timely charging and timely stopping of the charging state can be carried out.

[0038] A charging socket 19 for connecting to the controller is provided on the rear end face of the lower housing 1, and a dust cover 20 is provided in cooperation with the charging socket 19.

[0039] In the present invention, the battery unit of the lighting tool is a rechargeable storage battery. The storage battery is charged and stored through the charging socket 19, and the dust cover 20 is provided at the charging port to prevent dust from entering the charging socket 19 and ensure the charging efficiency.

[0040] The second placement rack 3 includes a support body 21 that is vertically surrounded on three sides, and a first nylon protective cover 22 is wrapped on the outside of any one of the support bodies 21.

[0041] In the present invention, the protective cover is a nylon layer wrapped around the partial outside of the support body 21. The material of the support body 21 is generally a metal material. Therefore, wrapping a nylon layer on the outside of the metal material can improve the comfort of holding by hand, and the nylon layer has wear-resistant properties, which can prevent damage caused by friction between the first support body 21 and the second support body 21 and the ground, and extend the service life.

[0042] A handle 23 is provided at the front end of the housing 1, and a second nylon protective cover 24 is wrapped on the outside of the handle 23.

[0043] In the present invention, the handle 23 is used for grasping during carrying, and the nylon protective cover protects the handle 23 and improves the comfort of grasping at the same time.
