Flexible connection power supply device

The invention provides a flexible connection power supply device including a power receiving side device (9) connected with a power consuming device and a power supply side device (8) connected with a power source electrically. The power receiving side device (9) can move along with the power consuming device so as to get close to the power supply side device (8), so that power supply can be realized. The power receiving side device (9) includes a bed frame (91) and a guide rod (92) supported by a support arm (93) fixedly connected with the bed frame (91). The guide rod (92) is slidably provided with a power supply plug device (94) electrically connected with the power consuming device through an extendable cable (940). 种弹性连接的供电装置，包括用于与用电设备连接的受电侧装置（9）以及用于与电源电连接的供电侧装置（8），所述受电侧装置（9）能够随所述用电设备而运动靠近所述供电侧装置（8）从而实现供电，其中，所述受电侧装置（9）包括基架（91）以及通过与所述基架（91）固连的支臂（93）而支承的导杆（92），所述导杆（92）上可滑动地安装有通过能伸长线缆（940）而与所述用电设备电连接的供电插头装置（94）。
