Embodiment

For the ease of the understanding of those skilled in the art, with reference to embodiment and attached drawing 1-2 the utility model is made into The explanation of one step, the content that embodiment refers to not are the restriction to the utility model.

Attached drawing 1-2, a kind of octal field-effect tube measurement jig, including bottom plate 1 are referred to, is fixed on the side at the top of bottom plate 1 Wall 2, is rotationally connected with the upper clamp plate 3 at the top of side wall 2, the top both sides of the bottom plate 1 are respectively symmetrically arranged at intervals with four and draw Line 4, lead 4 is each parallel to side wall 2.

The utility model by setting four leads 4 and 1 upper end of bottom plate to set side wall 2 respectively in the both sides of 1 upper end of bottom plate, Side wall 2 connects upper clamp plate 3, and octal field-effect tube can be fixed on to the gauge, and octal is corresponding electric with eight leads of gauge 4 respectively Connection, during measurement, ammeter pen is positioned on lead 4 and the electrical property of sample is measured, and the jig structure is simple, operation It is convenient, low manufacture cost.

Further, the upper end of side wall 2 is equipped with hinge, and the hinge includes the first hinge, the second hinge, for connecting the The shaft of one hinge and the second hinge, first hinge are connected with side wall 2, and the second hinge is connected with upper clamp plate 3.

The utility model is by hinge connection side wall 2 and upper clamp plate 3, and detachable maintaining is convenient, and cost is low.

Further, it is arranged with torsional spring in the shaft.

The utility model when fixing tested octal field-effect tube, can pass through the work of torsional spring by being arranged torsional spring in shaft Firmly, sample is clamped, so as to preferably fix sample.

Further, the upper clamp plate 3 includes the extension 32 outside the clamping part 31 and stretching side wall 2 parallel to bottom plate 1, Second hinge is fixed on clamping part 31.

The utility model by by upper clamp plate 3 be set to parallel to bottom plate 1 clamping part 31 and stretch out side wall 2 outside extension 32, second hinge is fixed on clamping part 31.In use, exerting a force to extension 32, after placing sample, upper clamp plate is decontroled 3, upper clamp plate 3 clamps sample by the active force of torsional spring.
