Abstract
The utility model discloses a blade-replaceable tapping knife composed of a handle, a knife rest and a blade inserted at the front end of the knife rest, wherein the end face of the front end of the knife rest is right-angled; the front end of the knife rest is provided with a slot for inserting the blade; and the slot is defined by a right-angled panel, turned edges at two sides of the right-angled panel and a bottom, the right-angled panel and the turned edges are vertical to the bottom, and the included angle between each turned edge and the right-angled panel is an acute angle. The blade-replaceable tapping knife has the advantages that the right-angled blade is high in tapping efficiency, convenient to replace and insert the blade, little in influence from an external force to the slot, stable in performance, easy to clean and still easy to replace the blade even if the blade is used for a long term.
Description
Technical field
The utility model relates to hand tools and makes the field, more particularly, relates in particular to the removable tapping knife of a kind of blade.
Background technology
At present, the removable tapping knife of the blade of being sold on the market, its structure generally is to be provided with an insert pocket at the knife rest front end, the slot of such tapping knife generally all is by the two-layer panel groove position that forms separated by a distance, in long-term use, panel can be collided or push unavoidably, after arbitrary deck panels in the two-layer panel is squeezed distortion, blade just is difficult to insert in the slot, uses not to be very convenient.
The utility model content
The purpose of this utility model is in order to solve the problem of above-mentioned existence, and it is convenient to provide a kind of blade to insert, and it is lower influenced by external force, the removable tapping knife of the blade of slot stable performance.
The utility model is achieved through the following technical solutions.
The utility model is the removable tapping knife of a kind of blade, it is made up of handle, knife rest and the blade that is plugged on the knife rest front end, knife rest front end end surface shape is a square, the front end of described knife rest is provided with the slot that is used to insert blade, this slot is formed by the crimping and the bottom surface encirclement of right angle panel, right angle panel dual-side, right angle panel and crimping are vertical with the bottom surface, and the angle of crimping and right angle panel is an acute angle.
The angle of above-mentioned crimping and right angle panel is a miter angle.
Advantage of the present utility model is, square blade rubber tapping rate of gum output height, and the blade exchange plug-in mounting is convenient, and it is little that slot is influenced by external force, stable performance, and clean easily, use blade still to change easily for a long time.
