Abstract
The utility model provides a four-edge wedge, and particularly relates to a firewood cutting tool. The four-edge wedge is mainly composed of a base. The base is a four-edge base. A circular cone head is arranged at the top end of the four-edge base. The four-edge base is composed of two square edges which are symmetrically arranged and two trapezoid edges which are symmetrically arranged. Air slots are formed among the adjacent square edges and the trapezoid edges. The four-edge base and a circular cone head structure are adopted, when firewood is chopped, the air slots among the adjacent square edges and the trapezoid edges ensure that vacuum can not be generated between the wedge and wood, the wedge can be easily pulled out, firewood cutting efficiency is improved, and the service life of the four-edge wedge is long.
Description
Technical field
The utility model relates to a kind of firewood instrument, is specifically related to a kind of four rib bavin points.
Background technology
The bavin point, it is a kind of firewood instrument, the bavin point mainly adopts circle or square base at present, pedestal extends the wide shape cutting edge that puts the first edge on a knife or a pair of scissors in the two sides, the bavin point of this spline structure in use the phenomenon that the bavin point is difficult to extract can occur, this is because the cutting edge of bavin point and the contact-making surface between the timber form vacuum, cause the bavin point to be difficult to extract, need bit by bit mobile bavin point of people, air is introduced in the attaching space between cutting edge and the timber, the bavin point could be extracted, this phenomenon has a strong impact on the operating efficiency of bavin point.
The utility model content
The purpose of this utility model provides a kind of four rib bavin points, and the bavin point that exists with the solution prior art is not drawn out easily, the problem of operating efficiency difference.
The utility model mainly is made up of pedestal, solving the technical scheme that its technical problem adopts is that pedestal is four rib pedestals, four rib pedestal tops arrange nose cone, four rib pedestals are made up of two symmetrically arranged square ribs and two symmetrically arranged trapezoidal ribs, form air groove between adjacent square rib and the trapezoidal rib
Above-mentioned nose cone surface arranges some tapered protrusion.
Above-mentioned square edge surface arranges some grooves.
The beneficial effects of the utility model are to adopt four rib pedestals and nose cone structure, in the firewood process, adjacent square rib and the air groove between the trapezoidal rib can be guaranteed can not form vacuum between bavin point and the timber, and the bavin point is easy to extract, firewood efficient is provided, and service life is also long.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1 pedestal, 2 nose cones, 3 square ribs, 4 trapezoidal ribs, 5 air grooves, 21 tapered protrusion, 31 grooves among the figure.
The specific embodiment
As shown in the figure: a kind of four rib bavin points, mainly formed by pedestal 1, pedestal 1 is four rib pedestals, four rib pedestal tops arrange nose cone 2, four rib pedestals are made up of two symmetrically arranged square ribs 3 and two symmetrically arranged trapezoidal ribs 4, form air groove 5 between adjacent square rib 3 and the trapezoidal rib 4, nose cone 2 surfaces arrange some tapered protrusion 21, and square rib 3 surfaces arrange some grooves 31.
Claims (3)
1. rib bavin point, mainly be made up of pedestal, it is characterized in that pedestal is four rib pedestals, four rib pedestal tops arrange nose cone, four rib pedestals are made up of two symmetrically arranged square ribs and two symmetrically arranged trapezoidal ribs, form air groove between adjacent square rib and the trapezoidal rib.
2. four rib bavin points according to claim 1 is characterized in that the nose cone surface arranges some tapered protrusion.
3. four rib bavin points according to claim 1 is characterized in that square edge surface arranges some grooves.
