Description
Technical field
The utility model is related to student's daily necessities field, especially a kind of adjustable clamp for test papers.
Background technology
The pressure weight of middle school student's school work at present will face a large amount of test daily, thus have numerous papers need to conclude it is whole
Reason.The method that Most current student uses is to fix to arrange using clip according to subject by different section's purpose papers to prevent from mixing
Disorderly, it is easy to find.But particularly high school student usually tests more, and paper accumulation is thick, sometimes has been over conventional snap
Range is gripped, is haveed no alternative but, needs to find clip arrangement again, thus needs a kind of clamp for test papers that can adjust clamping opening size, energy
The enough paper of gripping different-thickness and handout etc..In the Chinese utility model patent for being CN205929888U in notification number, announce
A kind of clamp for test papers changes by adjusting support construction the gripping range of the clip, but the support force of spring is utilized in the device
Amount, with the continuous expansion of clamping opening, support force will taper into caused by spring supporting, and gripping thicker paper roll then needs
The power of bigger, thus gripping will become more and more built on the sand.
Invention content
The purpose of this utility model is to overcome above-mentioned technical disadvantages to provide a kind of adjustable clamp for test papers, utilizes fixation
The strength returned home of torque spring offer, adjust connecting rod, do not interfere with the position of torque spring, thus power will not die down.
The utility model solve the technical solution that uses of technical problem for：A kind of adjustable clamp for test papers, including upper clamp holder,
Lower clamp holder, connecting rod, fixed structure and torque spring, the connecting rod are arranged between clamp holder and lower clamp holder, and with upper folder
Handle is hinged by hinge, and upper clamp holder can the rotation of around hinge hinge shaft；There are square apertures, connecting rod section among lower clamp holder to be square
And the square aperture is passed right through, connecting rod will not rotate at this time, and clamp holder will not misplace on top；Connecting rod one
Side has several fixed bayonets, for the insertion of fixed link to play the effect of fixed connecting rod；The fixed structure includes solid
Determine frame, support spring, adjusting block and fixed link, fixed link one end is connected with adjusting block and is arranged on fixed frame opening, adjusts
Block is in delta structure, and insertion fixed frame in bottom both ends prevents adjusting block from deviating from, adjusting block spring supporting supported, fixed link
In the fixation bayonet of other end insertion connecting rod, when to when adjusting block is pulled in direction residing for spring, fixed link is disconnected bar
Bayonet is fixed, connecting rod can move up and down at this time, unclamp adjusting block, and fixed link is pushed by adjusting block under the action of support spring
The fixation bayonet of connecting rod, then connecting rod position is fixed at this time；The torque spring is arranged between connecting rod and upper clamp holder,
Two torque arm are separately fixed in connecting rod and upper clamp holder, and the torsion needed for gripping has been provided.
Further, described support spring one end is disposed entirely in fixed frame, prevents support spring from collapsing；The adjusting
Block height is less than fixed frame height, and preventing from touching adjusting block when using accidentally makes fixed link be detached from fixed bayonet to cause device loose
It is dynamic.
Further, the upper clamp holder is equipped with protective pad with lower clamp holder clamp mouth part, prevents from damaging paper during gripping.
Further, the upper clamp holder holds handle with being equipped at lower clamp holder end with anti-skid chequer, is held when facilitating gripping, together
When anti-skid chequer play anti-skidding effect.
Further, the lower clamp holder holds handle center equipped with hanging hole, facilitates the placement after paper storage arrangement.
Further, the connecting rod lower end is equipped with the fixture block of protrusion, prevents connecting rod from causing device from the abjection of lower clamp holder
It is detached from.
Advantageous effect is possessed by the utility model：The structure design of the utility model is reasonable, can adjust the folder of clip
Take range simultaneously can firmly fixing device, and the gripping dynamics of clamp for test papers will not change with device, can be in any gripping model
Enclose it is interior clamped, using simple, arranged convenient for the storage of paper.
Description of the drawings
Attached drawing 1 is the cross-sectional view of the structure of the utility model.
Attached drawing 2 is the structure diagram of fixed structure described in the utility model.
Specific embodiment
1 ~ 2 pair of the utility model is described below below in conjunction with the accompanying drawings.
As shown in Figure 1 and 2, the utility model includes upper clamp holder 1, lower clamp holder 2, connecting rod 3, fixed structure and torque spring
9, the connecting rod 3 is arranged between clamp holder 1 and lower clamp holder 2, and hinged by hinge 4 with upper clamp holder 1, and upper clamp holder 1 can be around
4 hinge shaft of hinge rotates；It is square among lower clamp holder 2 there are square aperture 2-1,3 section of connecting rod and passes right through this and rectangular open
Mouthful 2-1, at this time connecting rod 3 will not rotate, clamp holder 1 will not misplace on top；If 3 side of connecting rod has solid
