In this embodiment, the two mutually matched connecting plates 202 can be fixed by the stopper head and the fixed shaft 207, and it is very difficult to rotate the connecting plates 202 at this time, which has the effect of stabilizing the lamp.

[0046] In a preferred embodiment, the end of the connecting shaft 205 is provided with an assembly hole, and the assembly hole is used to cooperate with the fixed shaft 207. The fixed shaft 207 can be in the form of a cotter pin. The fixed shaft 207 is inserted into the assembly hole to lock the connecting plate 202.

[0047] In a preferred embodiment, in addition to adopting the form of the above-mentioned embodiment, this embodiment sets a gap (for example, the gap is 5 mm, and the height of the convex teeth is smaller than the gap) between the fixed shaft 207 and the integral structure composed of the connecting plate 202, the gear ring 203 and the gear seat 204; the fixed shaft 207 passes through the end of the connecting shaft 205 and is connected to the eccentric wheel 206; the eccentric wheel 206 rotates forward to squeeze the connecting plate 202 so that the convex teeth on the gear ring 203 are matched and locked with the convex teeth on the gear seat 204. The eccentric wheel 206 rotates in the opposite direction to loosen the connecting plate 202. At this time, the connecting plate 202 is rotated forcefully to rotate the gear ring 203 so that the convex teeth on the gear ring 203 are meshed with different convex teeth on the gear seat 204. After the angle of the lamp is in place, the eccentric wheel 206 is rotated forward to match and lock the convex teeth on the gear ring 203 with the convex teeth on the gear seat 204. The structure involved in this embodiment is as follows: Figure 4 shown.

[0048] In a preferred embodiment, an adjustment plate 208 is provided on the eccentric wheel 206, and the adjustment plate 208 is L-shaped. It is more convenient to rotate the eccentric wheel 206 through the adjustment plate 208.

[0049] In a preferred embodiment, a strip groove is provided at the end of the adjustment plate 208, a threaded hole is provided at the side of the connecting plate 202, and the second screw 209 with a head passes through the strip groove and is connected to the threaded hole. In this embodiment, it is necessary to wait until the adjustment plate 208 is in place before inserting the second screw 209 into the threaded hole, and fix the second screw 209 to the connecting plate 202 by threaded connection to prevent the eccentric wheel 206 from rotating.

[0050] In a preferred embodiment, a strip groove is provided at the end of the adjustment plate 208, a second screw 209 is fixed to one side of the connecting plate 202, and the adjustment plate 208 is rotated so that the second screw 209 passes through the strip groove; the second screw 209 is fixed to the second torsion ring 210; the second torsion ring 210 is provided with a second threaded portion that matches the second screw 209 and a second torsion plate disposed outside the second threaded portion. In this embodiment, the second screw 209 is first fixed to the connecting plate 202, and in the process of rotating the adjustment plate 208, the second screw 209 passes through the strip groove, and is fixed by the second torsion ring 210 after it is in place, and the adjustment is also relatively convenient.

[0051] During use, when the angle of the lamp needs to be adjusted, first twist the second torsion ring 210 on the second screw 209 to allow the adjustment plate 208 to rotate. The rotation of the adjustment plate 208 drives the rotating eccentric wheel 206 to rotate, thereby reducing the clamping force between the connecting plates 202, so that the teeth (convex teeth) between the gear ring 203 and the gear seat 204 are no longer engaged, so that the angle of the connecting rod 211 can be adjusted to achieve the purpose of adjusting the angle of the lamp. When the angle is determined, one end of the adjustment plate 208 is fixed to the second screw 209 through the second torsion ring 210. The contact area between the gear ring 203 and the gear seat 204 is large and is not easily affected by ground shaking, thereby not affecting the angle of the bracket. For the angle adjustment of the connecting plate 202 or the lamp, the utility model provides a plurality of different embodiments, each of which can solve the problem of adjusting the angle of the lamp.
