请参阅图3至图5所示，灯头1上设有钣金支架11，钣金支架11上开设有扁平状的锁紧孔111；第一转轴24为圆柱轴，该第一转轴24两端的直径小于中间部位的直径，且该第一转轴24的两端均为扁平销结构，从而在组装第 一转轴24时，直接将第一转轴24的一端穿过锁紧孔111，并利用螺母241锁紧固定，即可实现第一转轴24与灯头1的固定。Please refer to Fig. 3 to Fig. 5, the lamp holder 1 is provided with a sheet metal bracket 11, and the sheet metal bracket 11 is provided with a flat locking hole 111; the first rotating shaft 24 is a cylindrical shaft, and the two ends of the first rotating shaft 24 The diameter is smaller than the diameter of the middle part, and both ends of the first rotating shaft 24 are flat pin structures, so that when the first rotating shaft 24 is assembled, one end of the first rotating shaft 24 is directly passed through the locking hole 111, and the nut 241 is used to Locking and fixing can realize the fixing of the first rotating shaft 24 and the lamp cap 1 .
第一转轴24的另一端则用于与第一连接件21相连。具体来讲，第一连接件21包括连接本体210、与连接本体210组装配合的端盖211以及收容在端盖211内的限位片212、止位片213、摩擦片214和垫圈215；第一转轴24的另一端依次穿过端盖211、限位片212、止位片213、摩擦片214及垫圈215，并最终通过螺母241锁紧固定。较佳的，止位片213和摩擦片214上的开孔也为扁平孔，以与第一转轴24的另一端相匹配，以便跟随第一转轴24转动。The other end of the first rotating shaft 24 is used to connect with the first connecting member 21 .

In addition, a frictional force is formed between the friction plate 214 and the washer 215 , and when the lamp cap 1 rotates to a proper angle, the lamp cap 1 can be fixed by the friction force to prevent the lamp cap 1 from sliding.
当然，在其他实施例中，也可以通过调整凸肋2131的大小以及两个凸包的位置，来扩大或缩小灯头1在水平方向上的旋转角度，此处对灯头1在水平方向上的旋转角度不作限制。Of course, in other embodiments, the rotation angle of the lamp head 1 in the horizontal direction can also be enlarged or reduced by adjusting the size of the convex rib 2131 and the positions of the two convex hulls.
