The tooth block 207 is engaged with the lifting block 212 through the first tooth groove 214. A fixing structure 3 is connected to the first support frame 201.

[0026] As a technical optimization solution of the utility model, the tooth block 207 is slidably connected to the first support frame 201, and a resistance block 205 is slidably connected to the inner side of the first support frame 201, and a first spring 208 is fixedly connected between the resistance block 205 and the tooth block 207, and a rotary block 204 is fixedly connected to the central axis 203, and two hemispherical protrusions are provided on the side of the rotary block 204, and a matching groove 206 is opened on the side of the resistance block 205, and the hemispherical protrusions on the rotary block 204 are in conflict with the side of the resistance block 205 through the matching groove 206. When in use, the first support frame 201 and the second support frame 202 are initially in an overlapping state, which is convenient for carrying and storing the floodlight, and because the resistance There is a certain distance between the contact block 205 and the tooth block 207, so that the side serrated part of the tooth block 207 can rotate in the first tooth groove 214 on the lifting block 212, so that the user can adjust the lighting angle of the floodlight body 1. When the first support frame 201 and the second support frame 202 are rotated to a triangular structure, the rotation of the central axis rod 203 will cause the rotating block 204 to rotate synchronously, and the hemispherical protrusion on the rotating block 204 will be separated from the matching groove 206 on the contact block 205, and at the same time, the contact block 205 will be pushed to the other side until the contact block 205 and the tooth block 207 are in conflict. At this time, the tooth block 207 cannot be retracted due to the obstruction of the contact block 205, and because the tooth block 207 and the lifting block 212 are in conflict, the tooth block 207 cannot be retracted. The first tooth groove 214 on the block 212 is in a meshing state, so that the current first support frame 201 and the floodlight body 1 cannot continue to rotate, thereby fixing the rotation position of the current floodlight body 1 and maintaining the stability of the lighting direction.

At this time, the tooth block 207 cannot be retracted due to the obstruction of the interference block 205, and because The tooth block 207 is in meshing state with the first tooth groove 214 on the lifting block 212, so that the current first support frame 201 and the floodlight body 1 cannot continue to rotate, thereby fixing the rotation position of the current floodlight body 1 and maintaining the stability of the lighting direction. On the other hand, in order to facilitate the adjustment of the setting height of the floodlight body 1, when the first support frame 201 and the second support frame 202 are in an overlapping state, the two first positioning grooves 209 at the end of the central axis 203 correspond to the positions of the positioning columns 210 respectively.

After the adjustment is completed, with the rotation between the first support frame 201 and the second support frame 202, the first positioning groove 209 will be staggered with the positioning column 210. At this time, the end of the positioning column 210 directly conflicts with the side of the central axis rod 203, thereby fixing the position of the current lifting block 212, thereby achieving the fixation of the entire device, ensuring the stability of the support of the floodlight body 1 during operation. When the floodlight body 1 needs to be hoisted and fixed, a pair of fixing plates 301 are respectively provided on both sides of the first support frame 201. The fixing plates 301 are in a storage state under the action of the torsion spring 304. When fixing, the user can rotate the fixing plate 301 on one side. Since the fixing plates 301 on both sides are meshed through the second tooth grooves 303,The two side fixing plates 301 will rotate simultaneously. After the side surface of the fixing plate 301 is parallel to the surface of the fixing plate 301, it can be fixed by bolts through the fixing holes 302. While being convenient for installation, combined with the support structure 2, the applicable range of the floodlight body 1 can be greatly improved.
