Bar by handlebar stem fold in handle placing groove, reduces rocking bar occupied space to play during prism transport
Effect, and then play the role of that handlebar stem is prevented to be damaged during transportation.
Further, the handle places groove sidewall and offers card hole, and the position that the handlebar stem corresponds to card hole is provided with
Bulb plunger.
Bulb plunger by using above-mentioned technical proposal, when by handlebar stem overturning in handle placing groove, on handlebar stem
It is fastened in card hole, to play the role of tentatively fixing handlebar stem, and then prevents handlebar stem bar from there is no the case where active force
Under it is backing out out of handle placing groove.
Further, the connecting plate and handlebar stem junction are provided with the limit sleeve for handlebar stem rotary spacing.
By using above-mentioned technical proposal, limit sleeve can prevent handlebar stem without limitation rotate, thus prevent handlebar stem because
Amount of spin is too big, cause rocking bar can not normal rotation, and then play the role of facilitating rocking bar to rotate
Further, rotary cylinder is arranged on the handlebar stem.
By using above-mentioned technical proposal, in the case where rotation, with hand centainly opposite can occur handlebar stem for handlebar stem
Rotation, and rotary cylinder can prevent the direct contact handle bar of the hand of operator, to play the role of protecting operator.
Further, the loop bar side wall is provided with the storage shell for placing rocking bar.
By using above-mentioned technical proposal, rocking bar is placed in storage shell, and storage shell can prevent outside rocking bar direct collision
The hard object in boundary, to play the role of protecting rocking bar.
Further, the storage shell section is arranged in Contraband type, and the storage shell side wall is hinged with far from one end of loop bar
Snap-gauge, the snap-gauge are connected on storage shell side wall far from one end of hinged place.
Snap-gauge is turned down by rocking bar card when folded rocking bar is placed in storage shell by using above-mentioned technical proposal
In storage shell, the free end of snap-gauge is connected on the side plate of storage shell, to play the role of blocking rocking bar, and then is played anti-
The only effect that rocking bar falls off from storage shell.
In conclusion the utility model has the following beneficial effects:
1, worm gear, annular groove and worm screw are used, improves the effect that prism adjusts efficiency to generate；

32 engagement of wheel；Worm screw 3 stretches out one end connection rocking bar 4 for placing shell 33, and rocking bar 4 includes the connecting plate 44 being hinged on worm screw 3, even
One end hinged handle bar 41 of the fishplate bar 44 far from worm screw 3.
Referring to Fig. 2, direct pull telescopic rod 11, is unable to control amount of tension, causes prism 1 when adjusting height, manually
Repeatedly pull finds suitable prism 1 highly back and forth, time-consuming and laborious in the adjustment process of prism 1；But the every rotation one of worm screw 3
Circle, worm screw 3 drive worm gear 32 amount of spin be it is fixed, it is also fixed that same worm gear 32, which drives the amount of tension of telescopic rod 11,
's；Only have operator to hold the rotation of handlebar stem 41 at this time, telescopic rod 11 can be driven to move up and down, starting can be fast when adjusting
Speed rotation, when prism 1 soon close to target position when, as long as slowly rotary worm 3, due to not having in entire adjustment process
It is reciprocal to adjust, therefore prism 1 rapidly can be adjusted to target position, to play the work for improving 1 height adjustment efficiency of prism
With.
Referring to Fig. 3, connecting plate 44 is hinged on 3 one end of worm screw, handle placing groove 45, handle placing groove is opened up on connecting plate 44
Card hole 47, one end hinged handle bar 41 of the connecting plate 44 far from worm screw 3 is arranged in 45 side walls, and 41 lateral wall of handlebar stem corresponds to card hole 47
Position be arranged bulb plunger 43, when handlebar stem 41 fold in handle placing groove 45 when, bulb plunger 43 is stuck in card hole 47,
Limit sleeve 46 is arranged in handlebar stem 41 and 44 hinged place of connecting plate, and limit sleeve 46 can prevent 41 overturning amount of handlebar stem excessive.
Referring to Fig. 3, rocking bar 4 is not needed in use, in order to avoid prism 1 collides rocking bar 4 in moving process, can will be
Hand lever 41 turns down in handle placing groove 45, while the bulb plunger 43 on handlebar stem 41 can be stuck in card hole 47, not led
Handlebar stem 41 will not fall off out of handle placing groove 45 in the case where power, to reduce the accommodating space of rocking bar 4, and then play
Protect the effect of rocking bar 4.
Referring to Fig. 3,12 side wall of loop bar is provided with storage shell 2, and storage 2 section of shell is arranged in Contraband type, and storage shell 2 is side walls hinged
