See also Fig. 1, shown in Figure 2, can clearly understand structural form of the present utility model, it mainly is made up of intubate 1 and the sleeve pipe 2 that is sleeved on the intubate 1, wherein:

This intubate 1 is in the interior collar 3 that an end is installed with just and intubate 1 inner edge is fitted, and interior collar outer rim is proper and the intubate inner edge forms the stair-stepping portion 11 that plugs together, plug together portion 11 both sides again and be provided with perforation 111, and the portion that plugs together is provided with reed 112 in perforation 111 root edge rivetings, these reed 112 two ends are straight again, and stage casing evagination one is the clamping end 113 of semicircle arcuation, and cooperates its flat end to be fixedly arranged on perforation 111 root edges, makes clamping end 113 just can slightly protrude out outside the perforation 111;

The internal diameter of this sleeve pipe 2 is identical with the portion that plugs together 11 external diameters of intubate, and just can be sleeved in the portion of plugging together 11, and intubate is in clamping end 113 positions of involutory reed again, be provided with just can push against contract in the reed 112 fasten projection 21

See also Fig. 3, shown in Figure 4, it is assembling back, plane of the present utility model cut-away view, when this sleeve pipe 2 is inserted in intubate 1, the fastening projection 21 and just can push against in the reed 112 and contract of sleeve pipe 2, be inserted in (as shown in Figure 3) in order to sleeve pipe 2: and fasten projection 113 by behind the clamping end 113 of reed in sleeve pipe, borrow the architectural feature of reed 112 homings, and sleeve pipe 2 is sticked on the intubate 1, sleeve pipe is engaged location (as shown in Figure 4) with intubate; And because the clamping end 113 that intubate 1 plugs together in the portion is a convex structure, make that sleeve pipe 2 can be after the appropriate application of force, sports cards is supported the clamping end 113 of projection 21 pushing and pressing reeds once again, and sleeve pipe is taken out, to form the grafting structure that a kind of directly application of force is taken out sleeve pipe.

Please cooperating again and consult shown in Figure 5ly, is the another kind of illustration of implementing of the present utility model, wherein:

This intubate 4 is in the interior collar 5 that an end is installed with just and the intubate inner edge is fitted, and interior collar 5 outer rims are proper and the intubate inner edge forms the stair-stepping portion 51 that plugs together, plug together portion 51 both sides again and be provided with slide rail 52, and tool one cascaded surface on this slide rail 52, and borrow bolt P lock to be provided with reed 53 in lower-order tread 521 ends, and the height of bolt P is a little less than higher-order tread 522, can not fasten bolt P during for sleeve pipe 2 slippages; This is locked on the reed 53 on the lower-order tread 521 again, and the one end borrows bolt P lock to establish and smooth on slide rail 52, and the other end then protrudes from higher-order tread 522 slightly, and forms a stop end 531;

The internal diameter of this sleeve pipe 2 is identical with the portion that plugs together 51 external diameters of intubate, and just can be sleeved in the portion of plugging together 51, and sleeve pipe 2 is in the position of involutory spring stop end 531, and being provided with just can slippage on the higher-order tread, and just can push against contract in the reed 53 fasten projection 22; Sleeve pipe 2 is provided with a through hole 23 on the body that fastens projection 22 ends again, and this through hole 23 just is positioned at spring stop end 531 tops of collar 5;

As Fig. 6, shown in Figure 7, can understand its motion mode, when sleeve pipe 2 was inserted in intubate 5, fastening projection 22 and just can pushing against in the reed 53 and contract of sleeve pipe 2 was inserted in (as shown in Figure 6) in order to sleeve pipe 2; And in sleeve pipe 2 fasten projection 22 by after the stop end 531 of reed, borrow reed 53 homing features, but and block in fastening projection 22 rear ends, so as to sleeve pipe 2 is engaged location (as shown in Figure 7) with intubate 4; And after this sleeve pipe 2 was inserted in the interior collar 5 of intubate 4, directly the application of force was extracted, because of reed 53 is that backstop is in fastening projection 22 rear ends; And after must borrowing through hole 23 insertions of pointed tool by sleeve pipe 2 two ends, press down with the stop end 531 that compresses intubate two ends reed 53 simultaneously, sleeve pipe 2 and intubate 4 taking-ups could be separated, to form the grafting structure that a kind of directly application of force is taken out sleeve pipe 2.
