Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

The utility model provides a novel composite suction tool, which comprises a first suction disc body 1, at least one second suction disc body 2 arranged in the first suction disc body 1 and a mounting structure 3 for fixing the second suction disc body 2 on the first suction disc body 1, wherein the first suction disc body 1 is provided with a first suction hole;

the first sucker body 1 comprises a first shell 11, a sponge body 12 fixedly arranged at the bottom opening position of the first shell 11 and a first connecting pipe 13 which is positioned at one end of the first shell 11 far away from the sponge body 12 and is used for being communicated with an external conduit;

the second sucker body 2 comprises a second shell 21 fixedly arranged in the inner cavity of the first shell 11, a first negative pressure cavity 22 positioned in the second shell 21, a second connecting pipe 23 positioned at one end of the second shell 21 and communicated with the first negative pressure cavity 22, and a suction opening 24 arranged at one end of the second shell 21 far away from the second connecting pipe 23; wherein the mounting structure 3 is screwed on the first housing 11 and the second connection pipe 23.

The second connecting pipe 23 penetrates through one surface of the first casing 11 far away from the sponge body 12, and is fixed on the first casing 11 through the mounting structure 3.

During the use, link to each other first connecting pipe 13 and second connecting pipe 23 with outside air exhaust equipment respectively, then make cavernosum 12 and object surface contact, at this moment, by under the combined action of first suction cup body 1 and second suction cup body 2, absorb the object, adsorb the object on second suction cup body 2 and first suction cup body 1, snatch, carry the object.

In one embodiment, the second housing 21 is made of a hard material; further, the second housing 21 is made of hard plastic; the suction opening 24 has a cross-sectional area at least smaller than that of the first negative pressure cavity 22.

In this embodiment, when snatching the soft-packing, under the absorption of outside suction apparatus, the soft-packing gets into second casing 21 earlier, and the bottom and the soft-packing surface of second casing 21 contact simultaneously snatch the object through a plurality of second suction cups 2 to lift the object effectively.

In one embodiment, a groove 25 is formed on the bottom of the second housing 21 corresponding to the outer side of the suction port 24;
