Be described as follows in order more to understand characteristics of the present utility model place, to lift now with next preferred embodiment and conjunction with figs., wherein:

Fig. 1 is the stereogram of the utility model one preferred embodiment.

Fig. 2 is the three-dimensional exploded view of the utility model one preferred embodiment.

Fig. 3 is the schematic representation that is provided with of the utility model one preferred embodiment.

See also Fig. 1, Fig. 2, the disassembling device 10 that the utility model one preferred embodiment is provided is to locate simultaneously in order to the inner and

outer pipe

12,14 that two pairs are worn mutually, wherein these outer tubes 14 are to be provided with a grooving 15 respectively at its top, 10 of this disassembling device include two collars 20, two bolts 30, two pivots, 40, two driving levers 50, and a connecting rod 60.

These collars 20 are c-shaped, be sheathed on the respectively top of this outer tube 14 respectively, the free end of these collars 20 is respectively equipped with a corresponding perforation 22, these collar 20 body portions also are respectively equipped with a screw 24, use for a bolt 25 spiral shells located therein, this bolt 25 also is resisted against this outer tube 14, uses these collars 20 and these outer tubes 14 are combined.

These bolts 30 are to include a head 32 respectively, and the whole body portion 34 extended by these head 32 central authorities and be arranged in the perforation 22 of these collars 20, and the free end of these bolt 30 body portions 34 then is provided with outside thread.

These pivot 40 body portions are provided with the screw vertical with its long axis direction 42, in order to the external thread spiro fastening of this bolt 30, use that these bolts 30 and these pivots 40 are combined.

These driving levers 50 are to include a cam part 52 respectively to be extended by its top, this cam part 52 includes two stopper sheets 54 parallel to each other, use body portion 34 to be located at therebetween for this bolt 30, respectively this stopper sheet 54 is respectively equipped with a through hole 55, use for this pivot 40 to wear, the bottom of these driving levers 50 is respectively equipped with a stomidium 56.

Two ends of this connecting rod 60 are to be provided with to give as security flower, and are arranged in the close-fitting mode in the stomidium 56 of these driving levers 50, use that this two driving lever 50 is linked together.

In addition, the body portion 34 of these bolts 30 also is arranged with a pad 36 respectively between its head 32 and this collar 20, and another pad 38 is used the effect that reduction frictional force is provided between these driving lever 50 cam part 52 and this collar 20.
