Specific embodiment
To make have a better understanding and awareness to architectural feature of the invention and the effect reached, to preferably
Embodiment and accompanying drawing coordinate detailed description, are described as follows：
The orientation such as " left, right, front and rear " for being previously mentioned in text of the present invention title, with Figure of description 1 as reference.
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of liftable, folding, the machine-carried forepoling device 1 for stretching, including multiple are cut with scissors successively
The support bracket 10 for connecing；The number of support bracket 10 is generally even number, is easy to symmetrical folding.The present invention provide support bracket 10 be
4.From centre to both sides, it is driven to stretch or fold by the first drive mechanism 11 between two neighboring support bracket 10.Also
It is to say, two, left side support bracket 10 is driven by first drive mechanism 11, two, the right support bracket 10 is by 1 first drive
Motivation structure 11 drives, and the right and left mirror image is set.
Support bracket 10 include body frame 12 and be arranged on the side of body frame 12 widen support 13；Widen the slip of support 13 to be fixed on
On body frame 12, and it is flexible on body frame 12 to widen support 13 by the driving of the second drive mechanism 14.Sliding fixed mode has many
Kind, such as socket, track slide fixed mode.The present invention is specific as follows by the way of socket：
Body frame 12 is the first support body being made up of rod member；The left bar 121 of the first support body, right bar 122 and with left bar 121,
The parallel intermediate bar 123 of right bar 122 is hollow structure；The support 13 of widening of its side is the second support body being made up of rod member,
Second support body include bottom bar 131 and be fixed on bottom bar 131 three left side bars 132 being parallel to each other, left side bar 132' and in
Bar 133；Left side bar 132, left side bar 132', middle bar 133, left bar 121, right bar 122, intermediate bar 123 are parallel to each other；Two left side bars
132 are located in the left bar 121 of the first support body, right bar 122 respectively；The second drive mechanism 14 is fixed with intermediate bar 123；Second
The middle bar 133 of support body is located in intermediate bar 123 and is driven by the second drive mechanism 14.It is two neighboring to add for the ease of folding
It is also articulated to together between width.
Embodiment 2
As shown in Fig. 3, Fig. 4, Fig. 5, in order that the width of advance support 1 is further increased, can be in body frame 12
Both sides all set and widen support 13.It is the epsilon-type structure being oppositely arranged that support 13 is widened in both sides.Accordingly, in intermediate bar
Two jacking the second drive mechanisms 14 in opposite direction are fixed with 123；Two widen support 13 be set in body frame 12
In hollow structure.Make to pack up, the overall volume of advance support 1 is smaller, the present invention widens support 13 using one of them
Following table interplanar distance between two left side bars 132 is equal to the upper table interplanar distance that another is widened between 13 liang of left side bars 132 of support
Characteristic, making two to widen the gathering of support 13 makes, and left side bar 132 overlaps, to reduce volume.Certainly, this needs body frame 12
Left bar 121, right bar 122 intracavity diameter slightly larger than two side rods diameter and.Certainly, two widen support 13 draw in when
Can not overlap, that is to say, that during gathering, two side rods for widening support are in coaxial state.
Embodiment 3
As shown in Figure 1 and Figure 2, on the basis of embodiment 1, the left side of the extending support body 10 in the left end of advance support 1
Lengthening support 15 is additionally provided with, the right of the extending support body 10 of right-hand member is equally also equipped with lengthening support 15.Lengthen support 15
Slip is fixed on widening on support 13 on the extending support body 10 of the left or right of advance support 1, and by the 3rd drive mechanism
16 drive lengthening support 15 to stretch.Equally, lengthen support 15 has various with the slip fixed form for widening support 13, can be set
Connect, or track is slidably connected.The present invention uses socket form, specially：
Lengthen support 15 be by an expansion link 151 be vertically fixed on the two ends of expansion link 151 and parallel two cross bars
152 triframe bodies for being formed；The bottom bar 131 for widening support 13 for folding the side of support bracket 10 is hollow structure, and expansion link 151 is wrapped
Interior bar 1511 and outer bar 1512 are included, interior bar 1511 can be slided in outer bar 1512.The cross bar fixed with 151 interior bar of expansion link 1511
152 are located in the bottom bar 131 for widening support 13, and the jacking end of the 3rd drive mechanism 16 is hinged on the outer bar of expansion link 151
On 1512.
Embodiment 4
As shown in Fig. 3, Fig. 4, Fig. 5, on the basis of embodiment 2, in the same manner as in Example 3, also lengthening branch is added at two ends
Frame 15.Difference is that two cross bars 152 for lengthening support 15 are located in two bottom bars 131 for widening support 13 respectively.For
It is easy to the fixation of the 3rd drive mechanism 16, the present invention has added sleeve pipe 153 expansion link 151 is outer again, and sleeve pipe 153 can be in outer bar
On 1512 slidably.The jacking end of the 3rd drive mechanism 16 is hinged on sleeve pipe 153, so, when interior bar 1511, outer bar 1512
When widening support 13 by two respectively and pulling to both sides, expansion link 151 is slided in sleeve pipe 153, and the 3rd drive mechanism 16 is not influenceed
Position.
