Preferably, an internal thread is arranged on the inner wall of the vacuum connector, an external thread is arranged on the outer wall of the suction nozzle, and the external thread and the internal thread are connected with each other through threads, so that the suction nozzle and the vacuum connector can be conveniently mounted and dismounted.

Preferably, the outer sleeve is made of a rubber material, the outer sleeve and the suction nozzle are fixedly bonded through resin adhesive glue, the outer sleeve is soft, and the outer sleeve can be better attached to an element through deformation when contacting the element, so that the adsorption effect is guaranteed.

Preferably, the cross-section of the annular plate is circular, so that the stability of butt joint of the sealing cover and the annular plate is ensured, the sealing cover can play a role in preventing air leakage, and the stability of the suction force of the adsorption element is ensured.

Preferably, the vacuum joint, the annular plate and the suction nozzle are all made of stainless steel materials, so that the structural strength is ensured, and the suction nozzle part cannot be damaged when being frequently adsorbed.

Preferably, the sealing cover and the circular ring are both made of polyvinyl chloride materials, so that the sealing cover is good in durability and not easy to damage.

Preferably, the end of the outer sleeve is provided with an annular bulge which can be better contacted with the element to adsorb the element.

Compared with the prior art, the beneficial effects of the utility model are that: through increasing the overcoat on the suction nozzle for the suction nozzle when with the component contact, better with the component laminating, thereby improve and adsorb stably, simultaneously, the butt joint of joint ring is joined in marriage to the sealed cowling, can avoid suction nozzle and vacuum joint to appear leaking gas and influence the stable effect of suction.
