Description
Affiliated technical field
The utility model relates to a kind of knife sharpener of grinding knife tool blade.
Background technology
At present, known have a kind of knife sharpener, this knife sharpener comprises bracing or strutting arrangement and two instruments sharpenning bars that are arranged on the bracing or strutting arrangement, one end of instruments sharpenning bar is hinged on the bracing or strutting arrangement, and two instruments sharpenning bars are arranged in a crossed manner mutually, are provided with spring between each instruments sharpenning bar and the bracing or strutting arrangement, spring trends towards the movable end of two instruments sharpenning bars to draw close, also be provided with on bracing or strutting arrangement and hold the cutter groove, the side that appearance cutter groove leaves the instruments sharpenning bar hinged end is an opening, and a side that relies on the instruments sharpenning bar hinged end is sealing.During use, with cutter put into hold the cutter groove and by the top to pressing down instruments sharpenning bar, drag cutter simultaneously back and forth because the effect of spring, instruments sharpenning bar can be close to the blade both sides of cutter cutter is carried out grinding, thereby reaches the purpose of sharpening.But this knife sharpener also exists some shortcomings.At first the instruments sharpenning bar of this knife sharpener all is to be made by iron and steel, and its grinding capacity is very restricted like this; Simultaneously, the spring that acts on instruments sharpenning bar is a disc spring, and this disc spring is arranged on the jointed shaft of instruments sharpenning bar, like this, when the sordid cutter of grinding, can be difficult to be cleaned totally if liquid on the cutter or residue enter into the torsion spring that connects jointed shaft.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective of prior art, provides a kind of grinding capacity to clean knife sharpener easily by force simultaneously.
Technical solution of the present utility model is that described spring is bar-shaped, and two springs lay respectively at the both sides that hold the cutter groove, and an end of spring is fixed on the jointed shaft of each self-corresponding instruments sharpenning bar, and the other end is fixed on the bracing or strutting arrangement.Like this, spring is located in the side of whole device, is easy to be touched and clean.This spring can be processed to the form of spring leaf or spring wire.
Further technical solution of the present utility model is that instruments sharpenning bar adopts the Hardmetal materials manufacturing in milled portion at least.The Hardmetal materials that adopts can be materials such as high siliceous silicate material, aluminosilicate material, pure silicon material, corundum, diamond dust material and quartz glass.Hardmetal materials is firmer, wear-resisting than ferrous materials, therefore can improve the grinding capacity of knife sharpener greatly.Described Hardmetal materials can make the milled portion that independent cemented carbide body is mounted to instruments sharpenning bar.
Further technical solution of the present utility model is that two instruments sharpenning bars are rectangle at the shape of cross section of milled portion at least, and two relative faces of rectangular cylinder are parallel to each other.Like this, when grinding knife tool, the grinding face of the whole width of instruments sharpenning bar all can contact with cutter, owing to have more grinding face, has shortened the time of whetting a knife, and has also improved the grinding capacity of knife sharpener.
Further technical solution of the present utility model is that described bracing or strutting arrangement comprises gripper shoe and base, holding the cutter groove is located on the gripper shoe, the both sides that hold the cutter groove on gripper shoe are provided with the gathering sill of guiding instruments sharpenning bar movable end action, and the movable end of instruments sharpenning bar is provided with pin and is connected with this gathering sill.
The jointed shaft that further technical solution of the present utility model is two instruments sharpenning bars is a pin, this pin by with gripper shoe on perforate cooperate realize hinged.Simultaneously, the structure of these two jointed shaft pins is identical with the structure that instruments sharpenning bar enters two interior pins of gathering sill, the diameter of the part that pin cooperates with gripper shoe is less than the diameter of pin remainder, while is provided with capping at the opposite side that pin is positioned at gripper shoe, and the diameter of this capping is greater than the diameter of pin and gripper shoe mating part.
