Furthermore, the vertical distance between adjacent branch groove openings on the same side is 1-2cm, preferably, the branch groove openings are uniformly distributed on two sides of the main groove opening, and the height of the branch groove openings on the two sides can be staggered with each other, so that the adjustment precision of the whole device is improved.
Further, the spring sleeve is established on the stand, and the spring below is the clamp plate, and the top is buckle spare.
Furthermore, the two ends of the spring are provided with gaskets, and the spring is contacted with the pressing plate or the buckle piece through the gaskets.
Furthermore, the clamping grooves are multiple and are evenly distributed on the outer surface of the upright post.
The utility model has the advantages that: the utility model discloses a cross stove tool can adjust the positioning height who compresses tightly the dress transposition in a flexible way according to actual need, and then adjusts closing device's pressure, through the cooperation of buckle spare, spring and draw-in groove promptly, adjusts closing device's pressure, guarantees to the effect that compresses tightly of PCB board, improves the yields.
