Accompanying drawing explanation

Fig. 1 is perspective view of the present utility model.

The specific embodiment

Below by the specific embodiment in connection with accompanying drawing, the technical solution of the utility model is further detailed and is described.

As shown in Figure 1, a kind of Tube adapter for drum membrane 1, the press resetting-mechanism 13, a flat pistol shape handle 14 being connected with the rear end of sleeve pipe 11 that comprise that a sleeve pipe 11, is movably set in that core bar 12 in sleeve pipe 11 is connected with core bar 12 with one press with described the position-limit mechanism 15 that resetting-mechanism 13 is connected with one.

Described handle 14 is provided with the anti-slip veins 140 of being convenient to gripping.Preferably, described handle 14 is structure as a whole with described sleeve pipe 11.

The described resetting-mechanism 13 of pressing comprises button 131 and a back-moving spring 132 for thumb press, this button 131 is connected with the rear end of described core bar 12, and and between described core bar 12, be set with a back-moving spring stop collar 133, this back-moving spring 132 is set in outside described core bar 12, and the rear end of sleeve pipe 11 described in its one end contact, back-moving spring stop collar described in its other end contact.

Described position-limit mechanism 15 comprises that a positive stop hook 151 and is arranged on the spacing hole 141 on described handle 14, this positive stop hook 151 comprises a connected hook portion 1511 and a bar portion 1512, this bar portion 1512 is connected with described button 131 through described spacing hole 141, and these hook portion 1511 active card are located on this spacing hole 141.

Preferably, described core bar 12, described button 131 and described positive stop hook 151 are structure as a whole.

Described sleeve pipe 11 is provided with that consistent sleeve-penetrating 11 inside and outside screwed hole 111, one set bolts 16 are spirally connected wherein to fix or pine oil is set in the core bar 12 in this sleeve pipe 11.

Operating process of the present utility model is as follows: pine oil set bolt 16, with the core bar 12 in pine oil sleeve pipe 11, and be that core bar 12 resets under the effect of back-moving spring 132, breather is placed in to the front end of core bar 12, forefinger and middle finger holds handle 14, thumb press button 131 promotes core bar 12 breather is accurately placed in to tympanum incision, and the bolt 16 that is then locked is with the core bar 12 in fixed sleeving 11, and then by handle 14, core bar 12 is extracted out from auditory meatus, complete and put pipe operation.

The above, it is only preferred embodiment of the present utility model, therefore can not limit according to this scope that this utility model is implemented, the equivalence of doing according to this utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that this utility model contains.
