Reference numerals: the tool bit comprises a tool bit 1, a handle 2, a ring stripping groove 11, a threaded hole 12, a stripping opening 13, a discharge opening 14, a handle tool bit jack 22, a bolt mounting hole 3 and a plug tool bit jack 4.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example one

Integral type ring broach, handle 2 is the arc, the longer one side of arc is the portion of gripping of being convenient for handheld, and the 1 fixed part of tool bit of one side for being used for setting up tool bit 1 of shorter, 1 welded fastening of tool bit is at 2 tip of handle, and tool bit 1 is higher than 2 inboards of arc handle, exceeds the part promptly as the tool bit 1 with the trunk contact, and the contained angle between the portion of gripping and the 1 fixed part of tool bit all can normal use at 90 ~ 180 within ranges, selects 120 ~ 140 usually.

The handle 2 usually adopts the hollow tube, and the hollow tube material is lighter, and hollow tube material can directly be purchased outward, and the quality is lighter, makes the girdling cutter have when better intensity, also portable.

The front end of the cutter head 1 is provided with a girdling groove 11 for girdling the bark, the bark falls off along the girdling groove 11, the girdling surface on the trunk is very neat, and the tree can not be damaged.

Example two

The split type ring barking knife comprises a handle 2 and a knife head 1 which are two relatively independent parts, wherein the knife head 1 is detachably arranged at the end part of one side of the knife head 1.
