The invention provides a contact sliding telescopic fan blade. The contact sliding telescopic fan blade comprises a plurality of contact sliding blocks and at least two stages of limiting clamping hasps. The contact sliding telescopic fan blade is characterized in that the contact sliding blocks are arranged on the surface of the telescopic fan blade and a sliding way to make contact with the fanblade, wherein the limiting clamping hasps are connected to the inner side of one end of the sliding way of each section of telescopic fan blade and the outer side of the other end of the sliding way,and at least two limiting clamping hasps are arranged in a linear array mode, so that at least one stage of buckle and two stages of disengagement prevention are formed; the cross section of one endof a sleeve fan blade is sealed and plugged, so that the fan blade is prevented from deforming and disengaging; the fan blade is provided with piers or pit grooves or T-shaped ribs, so that friction is reduced, and bending resistance is enhanced; the plastic, rubber or graphite contact sliding blocks and the fan blade are attached with a lubricating agent or graphite powder to make contact with the fan blade in a sliding mode, so that friction is reduced; and the strip-shaped contact sliding blocks protrude outwards or protrude inwards to make contact with the fan blade in a sliding mode, andthe fan blade is cleaned. According to the contact sliding telescopic fan blade, the fan blade is connected with an anti-disengagement safety part, multi-stage buckles are used for disengagement prevention, a safety rope is used for disengagement prevention, a power source is automatically turned off when disengagement is carried out, the telescopic range of the fan blade is enlarged, the diameterof a lamp does not need to be increased, and the lamp can be flexibly matched.

    触点滑动伸缩风扇叶片,包括:多个触点滑块和最少两级限位卡止搭扣;特征是:多个触点滑块设置在伸缩扇叶的表面和滑道上触滑扇叶;限位卡止搭扣连接在每节伸缩扇叶滑道一端的内侧和滑道另一端的外侧并分别最少直线阵列二个,形成最少一级卡扣二级防脱;套管扇叶一端横截面封塞加强扇叶不变形防脱扣;扇叶用墩子、坑槽或T型筋减少摩擦并加强抗弯力,塑料、橡胶或石墨触点滑块和扇叶粘附润滑剂或石墨粉滑触扇叶减少摩擦,条形触点滑块外凸或内凸触滑并清洁扇叶;扇叶连接防脱保险,多级卡扣防脱,保险索防脱,脱扣自动关闭电源,加大扇叶伸缩范围无须加大灯饰直径,灵活搭配灯饰。
