By adopting the technical scheme, the abutting section abuts against the through hole wall in the matching connection section of the motor rotating shaft, so that a relatively extruded sealing force is formed between the abutting section and the through hole wall, and better sealing between the abutting section and the motor rotating shaft can be realized, thereby achieving better sealing effect.

Further setting the following steps: the position of the sealing bulge, which is pressed against the motor rotating shaft, is an arc-shaped part which protrudes outwards.

Through adopting above-mentioned technical scheme, the setting of arc portion prevents that sealed arch from taking place local wear to guarantee sealed bellied leakproofness.

Further setting the following steps: the connecting section and the fastening section are perpendicular to each other.

By adopting the technical scheme, the mutually vertical arrangement ensures the shape strength of the connecting section and the abutting section, and better supporting and sealing are realized.

Further setting the following steps: the locking piece comprises a screw, and the screw penetrates through the shell to be in threaded connection with the motor.

Further setting the following steps: the seal comprises a sealing rubber pad.

Through adopting above-mentioned technical scheme, the gap that forms between the compensation casing that the elastic property of sealing rubber pad is better and the motor.

To sum up, the utility model discloses following beneficial effect has: the utility model discloses can realize the better sealed between casing and the motor to prevent to leak the emergence.
