Fig. 4 is the cutaway view of embodiment 2, and wherein telescoping tube 431 is in the natural situation that is not subjected to external force.

Fig. 5 is the cutaway view of embodiment 2, and wherein telescoping tube is flattened by lid.

With reference to Fig. 1, the extension sleeve group among the present invention is to be made of upper bush 1 and lower sleeve 2, and upper bush has double wall, and the space 113 of garden ring-type is arranged between its inner layer wall 111 and the outer wall 112, allows that just the sidewall 21 of lower sleeve inserts; Sidewall 21 upper semisections different with the lower semisection diameter thereby form one the circle shoulder 211, outer wall 112 lower edges have a hook that only is positioned on the section among three hook 1121(Fig. 1 that inwardly stretch out to see, then draw two hooks in addition in Fig. 3) prevent that in order to hook shoulder 211 upper and lower sleeve breaks away from; Aperture 114 is arranged on the upper bush, the tolerable circulation of air in case the sleeve group can stretch smoothly; There is little garden tube 121 in base plate 12 central authorities of upper bush, and the hole, garden 1221 of base plate 122 central authorities of little garden tube can allow stopper 3 pass, and the flange 31 at stopper top then can be blocked to deviate from by 1221 edges, hole; Bonding cover plate 123 above the little garden tube 121, shape cave, the garden 32 installing compression springs 33 in the stopper, the spring upper end then is buckled on the little garden post 1231 of cover plate central authorities; Plug head portion 34 can insert lower sleeve base plate 22 central authorities sucker hole 43 and with its sealing; There are three below the lower sleeve and fixedly only can see one that is positioned on the section among Chinese toon 23(Fig. 1), relative on the sucker 4 have three fixing holes 41, during manufacturing the fixing hole 41 of sucker is enclosed within fixedly on the Chinese toon 23, then fixing Chinese toon end is forged thick, sucker just by riveting below lower sleeve; The iron plate 42 of a garden ring-type is imbedded in the sucker the inside that rubber is made, and so fixedly the thick part of Chinese toon end can fasten iron plate 42, makes the sucker fixation; There is Da Yuan hole 47 in sucker central authorities, entangle the projection 221 of base plate 22 central garden shapes, keep closely preventing gas leakage between the two; Inner layer wall 111 at upper bush has three to projecting inward elastic hook 115, (upper bush is by plastic shaping, and only can see an offset hitch that is arranged on the section among the figure) flange 51 of a circle garden ring-type is arranged at ceramic cup 5 bottoms that are inserted in upper bush, elastic hook 115 hooks flange 51 cups and just can not come off.

Fig. 2 is the situation that is placed on table top, this moment, the weight of cup 5 was shunk the extension sleeve group, stopper 3 patchholes 43, and spring 33 is compressed, and cover plate 123 is pushed down stopper 3 makes its being inserted in tightly guarantee sealing in the hole 43, and the skirt section 46 of sucker is driven plain and is adsorbed on table top, the collision that the side direction aspect is come can not overturned cup 5, and vibrations or beat cup is risen make the elongation of extension sleeve group, but as long as spring 33 also stopper is pushed down and is filled in outstanding hole 43 and still can guarantee the firm of cup.

See sucker from the bottom surface in Fig. 3, the ring recess 45(that 43 both sides, hole of central authorities have two grooves 44 to be communicated with sucker skirt roots please consults Fig. 1 simultaneously), so sucker can arrive slots 45 via groove 44 after air enters from hole 43 when beginning to discharge, and sucker is discharged easily.(when sucker hole 43 and table top are closely connected, have only minimum slit can allow air pass through, if there is not groove 44, the flow of air just is limited very for a short time, makes at the moment of beginning sucker to discharge difficulty; The setting of slot 45 makes sucker skirt 46 needn't do very thickly near the root place in addition, and the edge can upwards not dug yet when sucker flattens.

Hole and lid that embodiment 2 shown in Fig. 4 and 5 and embodiment 1 main difference are in sucker; This has soft and telescopic telescoping tube 431 above sucker hole, being 3 on plane lid on telescoping tube is formed by cup 5 bottoms, cup weight is to pressing down when placed mesa, lid is the situation that has shown in Figure 5 with telescoping tube 431 compressions, the telescoping tube upper end mouth of pipe 4311 is plate-like, can be closely connected and keep air tight with lid 3, when picking up cup, telescoping tube extends with the work lid, after telescoping tube extended fully, lid promptly left the mouth of pipe 4311 again and to allow air enter sucker sucker is discharged to rising.

The form of above illustrated embodiment explanation the present invention structure can be done various distortion, application in the design when practical application, for example the inner layer wall 111 of upper bush can be formed by the bottom of cup, or cup forms one by the plastics manufacturing with upper bush; The projection 221 of the base plate of more for example (consulting Fig. 2) is directly through being dwindled, upper surface 222 can be contacted with the periphery 1222 of little garden tube end plate 122, and make lower sleeve sidewall 21 upper ends consult Fig. 1 with upper bush space 113 upper end 1131() do not contact, so sucker adsorbs desktop, gently stir cup with have gentle hands, cup just can rotate flexibly, has increased the enjoyment that plays; In addition, cup can be rotated flexibly, also can increase the number of turns of spring 33, make sleeve spring compacting when contraction state, only spring contacts with cover plate 123, and lower sleeve sidewall 21 upper ends do not contact with upper end, space 1131, and frictional resistance is just very little during rotation; Perhaps only insert suitable thickness on stopper 3 and between the cover plate 123 and the very little packing ring of frictional force also can; The implements that for example are supported again are not cups, but other article such as desk lamp, tellurion then can significantly dwindle the extension sleeve diameter, and sucker and settle base plate 22 diameters of sucker significantly to increase; Moreover the sucker allocation method can be without riveting at base plate, but suitable shape is made in the sucker coupling part, the base plate periphery that the garden that is enclosed within is tabular; Also upper bush can be made and have only outer wall and do not have inner layer wall or have only inner layer wall and do not have outer wall; All this kind distortion of doing with known professional technique, modification, application all belong to scope of the present invention.
