Consult Figure 10 (a), Figure 10 (b); Press telescopic leg button 18 in the handgrip portion 16 make in the telescopic leg 15 withdrawal pull bars 20 with drag link sleeve 11 on pull bar locating hole 12 break away from, go up handle simultaneously and make portion 16 on the pull rod device 14 and move, decontrol telescopic leg button 18 in the handgrip portion 16 behind the desired height position again and make telescopic leg 15 ejections in the pull bar 20; And extend in the pull bar locating hole 12 on the drag link sleeve 11; Chest is mentioned, consult Figure 11, because the pull bar locating hole 12 of a plurality of differing heights is arranged on drag link sleeve 11; So the height of pull rod device 14 can be in different pull bar locating holes 12 free adjustment; When mentioning the higher position, consult Figure 12, the ergonomics draw-bar box of the utility model just can have the chest of four pulleys to use at the bottom of common case.
Press once more telescopic leg button 18 in the handgrip portion 16 make telescopic leg contract 15 pull back in the bar 20 with drag link sleeve 11 on pull bar locating hole 12 break away from, go up handle simultaneously once more and make portion 16 and move on to its extended position on the pull rod device 14, consult Figure 13; Rotate pull rod device 14 again, make itself and box back surface shape at an angle, consult Figure 14; Enforce pull rod device 14 a little along pull bar 20 directions again; Make its boom mouth 3 from the bull stick device 1 of two coincidences and decide boom mouth 8 on the lever apparatus 7 and extend into and decide in the lever apparatus 7; Reach the telescopic leg button of decontroling in the handgrip portion 16 18 ejects telescopic leg 15 at the end in pull bar 20; Telescopic leg 15 will extend into three one of them of deciding in the bar hole 10 on the sidewall of deciding on the lever apparatus 7 vertical with boom mouth 8 planes like this, consults Figure 15; If just malposition do not stretch into just only need go up a little or under rotate that pull rod device 14 gets final product, pull rod device 14 has just arrived a use location like this; Use location height or the angle required because of the difference of user's stature height are different; Only need press telescopic leg button 18 in the handgrip portion 16 contracts telescopic leg 15 to pull back in the bar 20 and decide to decide 10 disengagings of bar holes on the lever apparatus 7; Go up again or the following pull rod device 14 of rotating is decontroled the telescopic leg button 18 in the handgrip portion 16 after reaching own comfortable height or angle, telescopic leg 15 is extend into decide on the lever apparatus 7 another to decide to get final product in the bar hole 10.
In the time will packing up pull rod device 14, only need above-mentioned action conversely just can, repeated description no longer here.
The specific embodiment two
Pull rod device described in this specific embodiment two is the two bar pull rod device of more piece.
Consult Figure 16 (a), Figure 16 (b), Figure 17 (a), Figure 17 (b), a pair ofly decide all respectively to have on the lever apparatus 28,8, four card bases 9 of a boom mouth have boom ditch 29 and movable ditch 30 and three to decide bar ditch 31 on the sidewall vertical with boom mouth 8 planes; Wherein, boom ditch 29 has tubaeform mouthful, decides bar ditch 31 below boom ditch 29 1 ends for three.
Consult Figure 18 (a), Figure 18 (b), a pull bar locating hole 12 is arranged on a pair of drag link sleeve 32, fixed screw holes 13 is arranged in the lower end of drag link sleeve, the same with the drag link sleeve of common more piece pull rod device.
Consult Figure 19, there is a pair of telescopic leg 15 bottom of pull rod device 33.
Consult Figure 20, there are 35, one telescopic leg buttons 18 of two pull bar mouths in the handgrip portion 34 of pull rod device 33, and two fixed screw holes 19.
Consult Figure 21 (a), Figure 21 (b), all respectively there is a fixed screw holes 21 a pair of pull bar 36 upper ends of pull rod device 33, and all respectively there is a drive link 22 inside, and all respectively there is a telescopic leg 15 bottom.
Remaining part in this specific embodiment two all with the specific embodiment one in the same; Method for using and order are too; But difference to some extent on pull pull rod device mode; Pull pull rod device mode than the specific embodiment one is more simple and convenient; The telescopic leg button 18 that still need press handgrip portion 34 in drag link sleeve 32 during pumping rod device 33 makes telescopic leg withdrawal pull bars with handgrip portion 34 fixing this joint pull bar bottom break away from following joint pull bars, but after the more piece pull bar all is stretched to its extended position, just can decontrol the telescopic leg button 18 of handgrip portion 34, the method for operating that back one goes on foot basic with the specific embodiment one in the same; Promptly rotate pull rod device 33; Make itself and casing 23 back side shapes at an angle, enforce pull rod device 33 a little along pull bar 36 directions again, make its boom mouth 3 from the bull stick device 1 of two coincidences and decide boom mouth 8 on the lever apparatus 28 and extend into and decide in the lever apparatus 28; In fact the telescopic leg 15 that this moment, pull rod device 33 most external one saved the pull bar bottom ejects; The telescopic leg 15 of this ejection can be along tubaeform mouthful boom ditch 29 arrival activity ditches 30 under the effect of thrust; Make pulling forward behind the commentaries on classics certain angle on the pull rod device 33 again; Telescopic leg 15 will arrive decides bar ditch 31, can and make its angle of rotating a certain size arrive the different bar ditches 31 of deciding through front and back push-and-pull pull rod device 33, and this is decided from the stature height by the user.
In the time will packing up pull rod device 33, only need above-mentioned action conversely just can, repeated description no longer here.
The professional of the industry can change the utility model through the concrete structure that changes the bull stick device or decide lever apparatus, as in the specific embodiment one, changing the quantity of deciding the bar hole of deciding in the lever apparatus, type shape, position, direction etc.; As in the specific embodiment two, changing the quantity of deciding the bar ditch of deciding in the lever apparatus, type shape, position, direction etc.; Or the relative position of bar ditch and boom ditch is decided in change; Promptly as make and decide the bar ditch above boom ditch one end, or an end that makes the boom ditch at middle part of deciding the bar ditch or the like; Or also can the bull stick device in the specific embodiment one or in the specific embodiment two with decide lever apparatus and be made of one, make them become parts; Or the bull stick device in the specific embodiment one or in the specific embodiment two can be split as two parts again; Again can in the specific embodiment one or the double-rod structure in the specific embodiment two change into the single pole structure; So above-mentioned change does not all change the protection domain that the cardinal principle of the utility model all belongs to the utility model.
