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.

A split-type 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.
