Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of movable folder of this utility model.
Detailed description of the invention
This utility model is described in detail, but it should say by each embodiment shown in below in conjunction with the accompanying drawings
Bright, these embodiments are not limitation of the utility model, those of ordinary skill in the art according to
Equivalent transformation in these embodiment institute work energy, method or structure or replacement, belong to this
Within the protection domain of utility model.
Please join a kind of detailed description of the invention of a kind of movable folder of this utility model illustrated in fig. 1.
In the present embodiment, a kind of movable folder, it is used for clamping cylinder, including: pass through branch sleeve
5 rigidly connected first clamp 1 and the second clamps 6, the internal screw rod 4 that is spirally connected of described branch sleeve 5, institute
End, the two ends activity stating screw rod 4 extends in the first clamp 1 and the second clamp 6.Screw rod 4 two ends end
Portion is respectively provided with the first abutting block 2 and second and abuts block 7, and described first clamp 1 and the second clamp 6 are equal
Take the shape of the letter U.The oral area of the first clamp 1 is formed with symmetrically arranged first clamping part 11, described second folder
The oral area of body 6 is formed with symmetrically arranged second clamping part 61, and described screw rod 4 is vertical in branch sleeve 5
To movement, described first clamp 1 is unequal with the opening amplitude of the second clamp 6.Concrete, this is first years old
Abut block 2 and be formed with the first circular arc bearing surface 21 towards the side of the opening of the first clamp 1, described second
Abut block 7 and be formed with the second circular arc bearing surface 71 towards the side of the opening of the second clamp 6, described first
The inner side of clamping part 11 forms the 3rd bearing surface 111, and the inner side of described second clamping part 61 forms the 4th
Bearing surface 611, to abut with the 3rd bearing surface 111 or the second circular arc by the first circular arc bearing surface 21
Face 71 and the 4th bearing surface 611 clamp cylinder jointly.The middle part of screw rod 4 is provided with external screw thread 41, even
The inside of female connector cylinder 5 is provided with the female thread 51 coordinated with external screw thread 41, so that screw rod 4 can connect
Realize in sleeve 5 vertically moving, to adjust the first circular arc bearing surface 21 and the 3rd bearing surface 111 flexibly
Between distance, or adjust the distance between the second circular arc bearing surface 71 and the 4th bearing surface 611,
So that by clamping the cylinder that diameter is different in the first clamp 1 or the second clamp 6.
Concrete, can effectively prevent by arranging the first circular arc bearing surface 21 and the second circular arc bearing surface 71
Sliding occurs when clamped condition in the most held cylinder, and improves cylindrical clamping effect.
In the present embodiment, the opening amplitude of this first clamp 1 is less than the opening amplitude of the second clamp 6.
