Extension bar be realized by articulation piece, and others be hingedly be arranged by pin shaft it is hinged.
In another technical solution, one end of the screw rod 47 is fixedly connected with one of side plate 42, another side
Plate 42 has the internal thread hole cooperated with the screw rod 47, and the length of the screw rod 47 is greater than the telescoping mechanism 4 and is reduced to the limit
When a pair of side plates 42 between spacing.
In another technical solution, the both ends of the tooling 3 are opposite to extend to form extension in side to its internal vertical
Part 31, the tooling 3 are fixed on 1 two sides of gate by extension 31.The setting of extension 31 can guarantee inside tooling 3
Gate 1 can be accommodated and freely open and close movement, also can guarantee being fixedly connected for tooling 3 and gate.
In another technical solution, the oil inlet and oil return pipeline of the auxiliary piping and hydraulic cylinder 2 passes through oil inlet and oil return pipeline
The threeway of upper setting is connected to.
In another technical solution, the maximum stroke that stretches out of telescoping mechanism 4 is stretched greater than the maximum of the hydraulic cylinder 2
Stroke out.In one embodiment, the maximum stroke 700mm that stretches out of telescoping mechanism 4 is greater than oil cylinder maximal dilation stroke 670mm.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
Other modifications may be easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
It is not limited to specific details and legend shown and described herein with novel.
