Further, from inhaling the jet pump in, lug and terminal box integrated into one piece, the processing of being convenient for improves the clean and tidy integration effect of product greatly.

Further, in the self-priming jet pump, the outer wrapping of half handle has the protective sheath unanimous with the terminal box material, forms the effect of integration.

Further, in the self-suction jet pump of the present invention, a plurality of grooves matching with fingers are concavely formed on the lower end surface of the upper linear portion, thereby improving the lifting comfort.

Further, in the self-priming jet pump of the present invention, a rubber pad is disposed in the groove to improve the lifting comfort.

The utility model has the advantages that:

1. the utility model discloses simple structure, reasonable in design has cancelled traditional external handle structure of the pump body, has designed the handle with the terminal box integral type, sets up lug isotructure and covers the coupling part of handle, has strengthened the outside holistic aesthetic property of product, promotes the integral type effect of promotion product in the vision.

2. The utility model has flexible and variable use state of the lifting handle, can meet the requirement of single lifting, can be split into two parts, is used for double lifting on the left side and the right side, and has higher practicability; and the single-person and double-person use modes of the handles are convenient to switch, two half handles can synchronously move relatively or oppositely only by rotating the threaded screw rod, the adjusting speed is high, and the operation is convenient.

3. The utility model discloses all adopt the material unanimous with the terminal box to spare parts such as lug, adjust knob, half handle, more do benefit to the uniformity of guaranteeing whole outward appearance, reinforcing vision integration effect.
