Still see Fig. 1, handle 6 fixedly was made of screw 64 face-to-face cooperation of two pieces of identical lobe pieces, handle 6 has push rod ring cavity 61, one push rod ring 62 is set in push rod ring cavity 61, the position placed in the middle on the top of push rod ring 62 has a button 621, button 621 probes into the button hole 65 at middle position place at the top of handle 6, and the position placed in the middle extension of the bottom of push rod ring 62 constitutes a push rod 622, push rod 622 is positioned at trombone slide chamber 41, end (being the end, lower end) at push rod 622 is installed with the push pedal 6221 that a shape is not subjected to illustrating restriction, and push pedal 6221 contacts with second top surface that pushes away post 521 of the 3rd actuating device 52 of aforesaid interior trombone slide guide bracket 5.By shown in Figure 2, position placed in the middle in the bottom of handle 6 is extended with one handle socket 63, on handle socket 63, offer a position and aforesaid handle fixing screw hole 44 corresponding handle socket fixed orifices 631, in handle socket 63 is inserted in the trombone slide chamber 41 after, screw in handle fixing screw hole 44 and handle socket fixed orifice 631 successively with handle fix screw 441, thereby handle 6 and interior trombone slide 4 are fixed.

The applicant narrates application of the present utility model in conjunction with Fig. 1 and Fig. 2, to use drag link mechanism to be example (promptly not using basket) 15 o'clock, taking interior trombone slide 4 by pull-out tube 2 is disposed on the recessed road 12 of a pair of slip of a side that is positioned at basket body 1 shown in Figure 2, specifically: pull-out tube 2 is interspersed in the pull-out tube slip vallecular cavity 131, and a pair of guide bracket of pull-out tube guide bracket 3 limits pin 33 and is slidingly fitted with the recessed road 12 that slides.When client enables drag link mechanism traction basket body 1, draw and the handle 6 and the carrying handle 6 that makes progress from drawing hole 66 with hand, because second dead bolt 511 of second blocking device 51 of the interior trombone slide guide bracket 5 of this moment probes into second lock hole 212 through second dead bolt hole 55, and compel to hold (pushing down) by the basal surface of interior trombone slide guide bracket 5 and push away post 321 in first of first actuating device 32 of pull-out tube guide bracket 3, first pushes away post 321, and to overcome the application force of second spring 322 descending, and by first push away first of post 321 lower ends cut somebody's hair 3211 second tiltedly carve face 3212 act on first dead bolt 311 first latch bolt block 3111 first tiltedly carve face 3112, the first dead bolts 311 are in retraction first dead bolt hole 36 under the application force that overcomes first spring 312 state.When therefore on handle 6, drawing, pull-out tube 2 also rose when promptly trombone slide 4 rose in handle 6 drives, when interior trombone slide 4 is taken pull-out tube 2 and is risen to the limit, when promptly rising to the degree that pull-out tube 2 can not rise again, also be the guide bracket of pull-out tube guide bracket 3 when limiting bottom that pin 33 is pulled outside pipe guide bracket 13 and stopping, aforesaid first dead bolt hole 36 is just corresponding to pull-out tube lock hole 1311.Because the interior trombone slide 4 of this moment still is in the pull-out tube chamber 41, therefore if will be then when outwards pull out in the pull-out tube chamber 21 of pull-out tube 2 with interior trombone slide 4, then press button 621 downwards, it is descending to make push rod ring 62 take push rod 622, spread to second of second actuating device 52 by the push pedal 6221 of the end, lower end of push rod 622 and push away post 521, second to push away post 521 descending, 522 compressions of the 4th spring.Since second push away post 521 second pushing block 5211 the 4th tiltedly to carve face 5212 be tiltedly to carve face 5112 with the 3rd of second latch bolt block 5111 of second dead bolt 511 of second blocking device 51 to match, therefore cut somebody's hair by second and 5211 act on second latch bolt block 5111, make second dead bolt 511 withdraw from second lock hole 212.Can outwards pull out interior trombone slide 4 from pull-out tube chamber 41 this moment, trombone slide guide bracket 5 is when the side that row goes out pull-out tube chamber 21 is pulled outwardly in interior trombone slide 4 is taken, because breaking away from (leaving) aforesaid first, the basal surface of interior trombone slide guide bracket 5 pushes away post 321, at this moment, first to push away post 321 up under the restoring force effect of second spring 322, first 3211 qualifications of removing first latch bolt block 3111 of first dead bolt 311 of cutting somebody's hair, promptly second tiltedly carve face 3212 and leave first and tiltedly carve face 3112, this moment first dead bolt 3111 under the restoring force effect of first spring 312 in the 3rd lock hole 213 door bolts are gone into pull-out tube lock hole 1311 to the chamber wall of the pull-out tube sliding cavity 131 of pull-out tube seat 13.Interior trombone slide 4 continues to draw outside pull-out tube chamber 21, when aforesaid second dead bolt 511 corresponds to first lock hole 211, under the restoring force effect of the 3rd spring 512, second dead bolt 511 is pushed in first lock hole 211, trombone slide 4 can't stretch out outside pull-out tube chamber 21 again in this moment, and promptly the degree of pulling out of interior trombone slide 4 reaches capacity.Under this state, interior trombone slide 4 is by first lock hole, 211 lockings on second dead bolt 511 and the pull-out tube 2, and pull-out tube 2 is by first

dead bolt

311 and 1311 lockings of pull-out tube lock hole simultaneously.The return course of inside and outside trombone slide 4,2 is with example, at first by operation to button 62, make second dead bolt 511 withdraw from first lock hole 211, interior trombone slide 4 is pushed in the pull-out tube chamber 21, when the basal surface of pull-out tube guide bracket 5 touches first when pushing away post 321 once again, first dead bolt 311 just withdraws from pull-out tube lock hole 1311, returns to initial position until inside and outside trombone slide 4,2, promptly until making handle 6 correspond to handle container cavity 14.At this moment, second dead bolt 511 is locked in second lock hole 212.
