Abstract: The present disclosure relates to a split-type footrest. The footrest includes a sucker, a shell and a foot-pedal. The shell is fixedly connected to the sucker. The shell is provided with at least one snapping part. The foot-pedal is correspondingly provided with a hanging arm, and the head of the hanging arm is provided with a lug. The lug is used to be inserted into the snapping part so as to form a detachable snap connection. There are snapping parts symmetrically provided on both sides of the shell respectively. There are two hanging arms and they are arranged on both sides of the foot-pedal respectively. Each hanging arm is provided with a lug, and each lug extends toward the other lug. The lugs are in one-to-one correspondence with the snapping parts. The foot-pedal and the main body can be disassembled for separate transportation, thereby reducing the cost of bulk transportation.

Abstract: The present disclosure relates to a sucker armrest of manual air suction type. The sucker armrest includes a handle, a cover and an air sucker. The handle is fixed on the cover, and the air sucker is fixed in the cover. The air sucker includes a manual air pump, a disc and a steel ring. The steel ring is embedded in the disc, and the cover is fixedly connected to the steel ring through screws. The manual air pump is provided between the disc and the cover. An air port of the manual air pump communicates with a suction surface of the disc. When the suction force of the sucker decreases, the manual air pump can be directly used for vacuumizing to increase the suction force, without the step of detaching and reattaching the sucker, which simplifies the process of re-increasing the suction force and improves the convenience of use.

Abstract: A method of making a heat radiating structure for high-power LED comprises: (1) preparing a PCB board, a heat conducting plate having a heat conducting column at one side thereof and a heat radiating plate; (2) providing a locating hole penetrating both sides of the PCB board, and welding a copper plate to one side of the PCB board, while soldering an electrode welding leg to the other side of the PCB board; (3) putting the heat conducting column into the locating hole, and soldering the copper plate and the heat conducting plate together; (4) placing the one-piece of the heat conducting plate and the PCB board produced by the step (3) on a pressing equipment to adjust the height of the conducting column; (5) pasting the inner side of the heat radiating plate on the other side of the heat conducting plate fixedly.
