Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1-5, the present invention provides a technical solution: a waterproof pressing pump comprises a suction pipe 1, a connecting rod 3, a pump body 4, a pressure rod 6, a bushing 10, a waterproof ring 11 and a pressing head 12, wherein the connecting rod 3 and the pressure rod 6 are both of tubular structures, and the suction pipe 1, the connecting rod 3 and the pressure rod 6 are mutually communicated; one end of the pressure lever 6 is connected with the pressing head 12, and the other end of the pressure lever 6 is arranged in the pump body 4 and connected with the connecting rod 3; a piston 5 is arranged in the pump body 4 in a matching way, and a pressure rod 6 penetrates through the piston 5; the waterproof ring 11 is sleeved outside the pressure rod 6, a bushing 10 is arranged on the lower side of the waterproof ring 11, the bushing 10 is connected with the bottom end of the pressure rod 6 through threads, and a spring 7 is arranged between the bushing 10 and the pressure rod 6; the bottom of the pump body 4 is connected with the connecting rod 3, and a sealing ball 2 is arranged at the joint of the bottom of the pump body 4.

Further, a coil 8 is arranged outside the bushing 10, and a gasket 9 is arranged between the coil 8 and the waterproof ring 11; the gasket 9 is made of a rubber material.

Furthermore, a through hole is formed in the end face of the bottom of the bushing 10, and the pressing rod 6 is matched to penetrate out of the through hole.
