The invention has the beneficial effects as follows, utilize a crystal head to realize repeatedly crystal head wiring experiment, easy to operate, save material.

Brief description of the drawings

Fig. 1 is structural representation of the present invention

In figure, 10. main part, 11. draw-in grooves, 12. back-moving spring 1,13. projections, 14. pressing line modules, 15. vertical guide slot, 16. golden fingers, 17. series component, 18. back-movingspring 2,20. base plates, 21. horizontal guide grooves, 22. grooves, 30. cutting ferrules, 31. line ball windows, 32. cards, 40. hinges.

Embodiment

Known by above-mentioned accompanying drawing, embodiments of the present invention are:

Embodiment 1:

Preparation before line ball, closed main body (10), projection (13) and groove (23) fastening, slip cutting ferrule (30) is to the low order end of horizontal guide groove (22), now, card (32) embeds in draw-in groove (11), and line ball window (31) overlaps with the position of pressing line module (14).

Line ball process is identical with light water crystal-tipped mode of operation, after line ball completes, being insulated eight golden fingers (16) entirety that series component (17) group fixes on together moves down, contacts with the each strip metal heart yearn of twisted-pair feeder respectively, back-moving spring is in compressive state, two station ends of pressing line module (14) are embedded in the below of card (32), and pressing line module (14) is fixed on twisted-pair feeder one end in crystal head.

Connect correctness test, operate identically with the test operation of light water crystal-tipped, can use general tester to test.

Again the preparation of line ball, slip cutting ferrule (30) is to the high order end of guide groove, strike out main part and base plate with the hand, crystal head is in open mode, pressing line module (14) automatically resets to initial position, the now combination of golden finger and netting twine is no longer tight, takes out after netting twine, automatically resets to initial position by golden finger (16) entirety of series component (17) combination.

Specific embodiment described herein is only to the explanation for example of the present invention's spirit, those skilled in the art can make various amendments or supplement or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
