As preferably, described left compact heap and right compact heap specular.
In order to better install compact heap device, as preferably, described splicing block group has at least two sides to recline mutually with compact heap installing hole hole wall.
Conveniently mount and dismount, as preferably, described splicing block group has at least two sides to be cancave cambered surface, forms break joint between described cancave cambered surface and described compact heap installing hole hole wall.
Further, as preferably, the cross section of described splicing block group is octagon, and the side of described splicing block group comprises the cancave cambered surface that forms break joint between four with described compact heap installing hole hole wall and two and the side reclined mutually with compact heap installing hole hole wall.
As preferably, described compact heap device device is also shaped with channel bar mounting groove, and described channel bar mounting groove runs through described folder hole groove, and channel bar mounting groove two ends extend on two sides of compact heap device, are provided with channel bar in channel bar mounting groove.Clamping portion is shaped with the caught workpiece of slotted eye, as perforation shell case, the clamping portion of the head of perforation shell case is shaped with fluting, because needs and other assembly parts have depth of parallelism demand, therefore often certain angle need be rotated, when adopting common square steel to rotate in the middle of groove, groove portion can be caused to split, destroy the groove milling both sides depth of parallelism, channel bar of the present invention is arranged in the fluting of caught workpiece, effectively can ensure clamping process, and the fluting size of caught workpiece is unaffected, rotate after clamping, caught workpiece fluting position can not be ftractureed or be out of shape.
As preferably, described locating piece side is provided with the locating hole suitable with described channel bar mounting groove, and the two ends of channel bar extend in locating hole.Channel bar is connected in locating hole, and channel bar firmly can connect locating piece and compact heap device.
As preferably, described handle is shaft-like, and handle one end is provided with the external screw thread matched with described handle installing hole, and one end is provided with column handle portion.
As preferably, described compact heap installing hole is arranged in the middle part of described locating piece.
The beneficial effect that the present invention brings is, structure of the present invention is simple, and easy for installation, rapid operation, better can ensure clamping precision.
