Described spring mechanism be fixed on the extension spring between the left and right jaw or be fixed on left jaw and left fixed head between stage clip.
Described haulage gear is the stay cord that is fixed on the left jaw outside, or is fixed on the pinion and rack in the left jaw outside.
The two ends of left and right two fixed heads are provided with through hole, the polished rod bolt passes through hole fixedlys connected with driving chain, have realized being connected between clamp body and the driving chain, define the maximum vibration amplitude of clamp body simultaneously.
The diameter of described through hole is greater than the diameter of polished rod bolt.
The invention has the advantages that:
1, the jaw on the clamp body is free to slide on connecting rod, can realize the free adjustment when the different size wiring board is installed, and is applied widely;
2, clamp wiring board by spring force on the clamp body, it is flexible with removal to be installed;
3, cooperate rotation by the vibrations wheel of clamp body below support with eccentric wheel in the vibrations unit, the realization clamp body is to the vibrations of wiring board, and it is little to shake required power, the efficient height.
