The specific embodiment:

See Fig. 1, the inclusion 1 of described knapsack is fixed with two respectively and longly is with 21 and 31 and two weak points to be with 22 and 32, wherein length is fixed with the top of 21 and 31 1 ends and inclusion 1, length is with 21 other ends to be fixed with socket 23, length is with 31 other ends to be fixed with plug 33, weak point is fixed with the bottom of 22 and 32 1 ends and inclusion 1, its short-and-medium 22 other ends of being with are fixed with plug 24, weak point is with 32 other ends to be fixed with socket 34, socket 23 constitutes a pair of eye-splice with plug 24, and plug 33 constitutes another with socket 34 makes knapsack be in user mode shown in Figure 1 to eye-splice; When plug insertion socket, the hole clipping inner face that a pair of shell foot on the plug snaps in socket is fixed on plug in the socket, has only with hand the card base on the plug is inwardly pressed and will simultaneously plug be transferred to from socket, plug could be separated with socket, is prior art; The fixed edge that protects cloth 11 is connected the junction 101 of inclusion bottom and inclusion side, the cloth 11 that protects in the state shown in Figure 1 covers castor and the leg (details of castor and leg is seen below) that is arranged on inclusion 1 bottom, active edges (away from one side of the junction 101) both sides of protecting cloth 11 are respectively equipped with the magic and paste and paste correspondingly with the magic that is arranged on inclusion lower sides and bottom, and state shown in Figure 1 is that the magic of protecting the cloth upside is pasted magic subsides with inclusion 1 bottom and fit together mutually to make and protect cloth 11 and cover castor and leg bottom the inclusion.User mode figure when Fig. 1 backs on the body for knapsack.

Fig. 2 is placed on user mode figure when towing on the ground with the knapsack among Fig. 1, plug among Fig. 1 24 and 33 is transferred to from

socket

23 and 34 respectively, and will make two long movable ends as shown in Figure 2 fixed with each other in the plug 33 insertion sockets 23 with 21 and 31, again the cloth 11 that protects among Fig. 1 is turned over and covers two weak points to the front side wall of inclusion 1 and is with 22 and 32, and make the magic subsides of protecting cloth movable end downside among Fig. 1 paste (not drawing among the figure) applying, state as shown in Figure 2 with the magic of inclusion front side wall; And then the castor 4 of inclusion bottom and leg pulled out get final product, during use, hand hold length among Fig. 2 be with 21 and 31 or plug 33 and socket 23 knapsack can be towed.

See Fig. 3, it is the enlarged drawing of knapsack bottom direction among Fig. 2, from Fig. 3 as seen, the bottom of inclusion 1 is fixed with back stall 6 and is used to support inclusion 1, be fixed with two groups of castors 4 and two legs 5 on the back stall 6, wherein two legs 5 are arranged in the storage tank 63 of back stall, be inserted with left inserted block 51 and right inserted block 52 between leg 5 both sides and the storage tank 63 respectively, when being installed, leg 5 earlier a left side is stretched at axle two ends of passing leg 5, the blind hole of right inserted

block

51 and 52 both sides is then with a left side, right inserted

block

51 and 52 two breach that insert in the storage tank 63 (are the breach 631 among Fig. 4,632) can leg 5 is fixing in; See Fig. 5, leg 5 both sides are respectively equipped with locating slot 501 (only seeing the locating slot of a side among Fig. 5), match and be respectively equipped with two locating slots that are mutually on 90 degree location convex tendons and the leg in left and right inserted

block

51 and 52 inboards towards leg 5; Two location convex tendons 521 and 522 on the right inserted block 52 as shown in Figure 7, locating slot on the leg 5 during state shown in Figure 3 among Fig. 5 snaps in the location convex tendon 521 among Fig. 7 and matches, and rotation leg when making it to be hidden in the storage tank 63 of back stall 6 when state (shown in Figure 1), locating slot on the leg 5 among Fig. 5 snaps in the location convex tendon 522 among Fig. 7 and matches, location convex tendon on the inserted block of a left side is similar, no longer stating more.

The wherein three-dimensional exploded view of one group of castor among Fig. 3 is seen shown in Figure 8, passing drive-connecting shaft 74 two ends of the axis hole of fixed page 71 passes two wings 721 on the active page 72 respectively and makes active page 72 and fixed page 71 constitute hinge, wheel carrier 73 usefulness screws are fixed in the active page 72, castor 4 is articulated on the wheel carrier 73 by axle 75, and fixed page 71 is provided with card base 712.After the castor shown in Figure 8 assembling as shown in figure 11.

See Figure 10, four hole clippings 65 that the fixed page 71 that constitutes hinge is provided with on the back stall among four card bases 712 and Fig. 4 match, when castor is installed, only need the card base on the castor assembly among Figure 11 712 is snapped in the hole clipping corresponding among Fig. 4 65 and fixed page can be fixed in the back stall, the cavity volume 64 of then clubfoot 411 of cartridge clip shown in Figure 9 41 being put into Fig. 4 makes the double-screw bolt 412 on Fig. 9 pass bar hole 641 backs and nut coupling of Fig. 9, make cartridge clip constitute the locking mechanism that is arranged between castor and the back stall, this moment, nut can not be twisted too tightly, otherwise double-screw bolt can not slide along bar hole.

See Fig. 3, if shoulder knapsack, then earlier with 5 groups of two legs to storage tank 63 central authorities, two legs are hidden in the storage tank 63 fully, again with cartridge clip 41 to drawing away from the direction of containing cavity 62, the cartridge clip 41 that makes card push down active page one side separates with active page, castor is ploughed under in the containing cavity 62 then, another castor then ploughs under in the containing cavity 61, and then it is multiple to back stall 6 to protect cloth 11, make the magic of protecting on the cloth 11 paste with back stall on the magic fit together and shelter from castor and leg; At last the plug among Fig. 2 33 is transferred to from socket 23, again with the long band of correspondence and short with on plug, socket plug together the state that together promptly obtains as shown in Figure 1.
