Structure is dug using flat hole, but the flat hole of traditional technology chisel stability in use is relatively limited, and is difficult to ensure processing
Efficiency and quality, so applicability and practicability are restricted.
Summary of the invention
The flat hole reasonable and practical the purpose of the utility model is to provide a kind of structure setting digs structure.
The technical solution for realizing the utility model aim is a kind of flat hole chisel structure, including installation chisel grip and integrated molding
Structure is dug in the hole of installation chisel grip bottom end, the hole chisel structure includes top connector and bottom end chisel edge portion, the bottom chisel edge
Portion is slab construction, and the bottom surface in bottom end chisel edge portion is inclined surface and inclined surface is connected from the chisel edge in bottom end chisel edge portion to top
Portion's inclination, the bottom surface in bottom end chisel edge portion are lower than the top surface of top connector, and the installation chisel grip is fixed on top connector
Center line on, in the bottom end chisel edge portion setting there are four cross bits through-hole, on the top surface bottom edge two of the top connector
End is symmetrically arranged with raised blade, is uniformly fixed with and inclines between the top surface in bottom end chisel edge portion and the bottom surface of top connector
Inclined stiffener bar is provided at least one installation cavity on the side wall of the installation chisel grip, and in the table of the installation chisel grip
Vertical rib is fixed at the top of face.
It is fixed with reinforcement support rod between the top surface and the installation chisel grip side of the top connector, described
The top surface in bottom end chisel edge portion is provided with ripple dust lead raised line.
The length in bottom end chisel edge portion is 127mm and width is 31.2mm, it is described protrusion blade length be 30mm and
Width is 10mm.
The utility model has the effect of positive: the structure setting of the utility model is reasonable, and it is convenient to operate, can be effective
The efficiency punchinged is improved, and its integral strength is high, is conducive to improve it using reliability, while also facilitating and tying with driving
Structure is connected to a fixed, and guarantees use reliability, strong applicability and practicability is good.
