Hold the thickness of 2～3mm outside groove notch；Then, cydariform friction plate is stretched out under the left and right two ends of holding tank
Two head part of side do not load two locating slots, and the elastic pressing element being pressed against in groove；Finally, adjust
Spacing between whole two clamping plates, makes the both sides cell wall of holding tank tightly clamp cydariform friction plate, and clamping is complete
Becoming, test can start.
Further, two clamping plates can be locked by the locking element of multiple adjustable relative spacing, such as lock
Buckle structure, elastic card claw etc., a kind of simple in construction and the locking element being prone to adjust are clamping screw pair of nut,
Two clamping plate are locked by least one pair of clamping screw pair of nut, it is to avoid clamping plate relatively rotate, in the correspondence of clamping plate
Offering through hole on position respectively, the bar portion of clamping screw passes from through hole activity, and locking nut is tightened on bar portion
On tail end.When adjusting holding tank groove width, it is only necessary to turn locking nut.
Further, elastic pressing element can be reed, spring coil or helical spring etc. other have similar
The structure of function.
Further, on two clamping plates, correspondence is offered screw thread and is installed through hole, by grip of testing machine mounting seat
The screw rod of configuration has got final product cost apparatus clamping on universal testing-machine in loading screw thread installation through hole, convenient
Fast, and be beneficial to change fixture.
The beneficial effects of the present invention is:
1, according to test requirements document, cydariform friction plate can be carried out abundant clamping, and difference can be applicable to
The friction plate of thickness a, it is achieved that folder is multiplex；
2 with being connected of general frictional testing machine, it is possible to utilize universal testing-machine to complete test, and tear open
Dress is convenient；
3, simple and reliable for structure, it is simple to popularization and application.

Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Fig. 1～2, the vertical clamping plate 1 of lateral arrangement are abnormity flat board, and its upper limb 101 is upwards
Left and right the two of one section of prominent arc-shaped step face, end, upper limb 101 left and right two ends and clamping plate 1 erect edge 102,
103 connect, and two erect edge 102, and 103 are positioned at upper limb 101 two ends tip inside.Clamping plate 1 first half is symmetrical
Having offered two through holes, lower half is offered screw thread and is installed through hole 104.
Such as Fig. 3, shown in 6 and 7, locating slot 5 has been offered in end, vertical clamp bar 3 upper end, and locating slot 5 is built-in
Enter an elastic pressing element 6 stretched out towards notch.Elastic pressing element 6 in figure is spring coil.
Such as Fig. 4, shown in 5 and 6, the step surface keeping two clamping plate upper limbs 101 is relative and concordant, presss from both sides two
Plate 1 interlocking is integrated, and two clamping plate 1 are locked by a pair clamping screw pair of nut, the bar portion of clamping screw from
Through hole activity passes, and locking nut is tightened on bar portion tail end.Two upper limbs 101 surround the clamping of an arc
Groove 4, left and right two openings of holding tank 4 are exposed at both side edges 102 respectively, outside 103, two clamping plate 1
Can in opposite directions/reversely relative movement is to reduce/to increase the groove width of holding tank 4, below holding tank 4 two ends,
Against both side edges 102,103 are respectively configured a vertical clamp bar 3, and two clamp bars 3 are arranged on same by bolt
On one piece of clamping plate 1, end, clamp bar 3 upper end is respectively just to end, upper limb 101 two ends, the opening of locating slot 5
