The end of the lead wire is installed on the locking mechanism, and the other end is connected to the equipment that needs power supply. The locking mechanism is clamped on the bare wire on the utility pole to realize connection. Electricity, the locking mechanism is composed of a locking frame, a first pressure block, a first guide column, and a first spring. The first pressure block and the first guide column are fixedly connected together and are slidably matched with the locking frame. The first spring It is set on the first guide column between the first pressing block and the lower end of the locking frame. The supporting mechanism is connected with the locking mechanism to control the opening and locking of the locking mechanism on the bottom surface. The supporting mechanism includes a supporting tube, a connecting Tube, clamping mechanism, the connecting tube is set in the support tube and is slidingly fitted with the support tube, the clamping mechanism is installed in the connecting tube through screws, when wiring, the clamping mechanism and the clamping groove are controlled to achieve clamping connection, and the support tube enters the second The locking mechanism is supported in the groove, so that the first guide column slides downward by pulling the connecting pipe, the first spring is compressed, and the supporting pipe is controlled to install the locking mechanism on the bare wire on the pole, and the connecting pipe is loosened. Due to the elastic force of the first spring, the first pressing block and the locking frame clamp the bare wire, and the locking mechanism is controlled to disengage from the card slot, so that the supporting mechanism is separated from the locking frame, thereby achieving the effect of high-altitude connection , when it is necessary to disassemble the locking mechanism from the bare wire installed on the utility pole, operate the support mechanism in the same way, first control the support tube to enter the second groove, and then control the connecting tube to slide upward along the support tube until the card installed in the connecting tube The tightening mechanism touches the bottom end of the first guide column, controls the clamping mechanism, and realizes the clamping connection between the clamping mechanism and the slot on the first guide column, pulls the connecting pipe, the first guide column slides downward, and the first pressing block The distance between the locking frame and the locking frame is opened, so that the locking mechanism can be disassembled from the bare wire installed on the utility pole.
