Description

Hand held sharpening apparatus

Technical field

The utility model relates to a kind of sharpening apparatus, and particularly a kind of alternative staff is directly held the hand held sharpening apparatus of cutter.

Background technology

In the sharpening process of flat cutter, the high temperature that the friction of cutter and emery wheel produces is scalded finger easily, and directly be difficult to each point of a knife sharpening of cutter is become sustained height with holding the cutter tool sharpening, because need rotary cutter during each point of a knife of sharpening, directly lose benchmark easily, so can cause each point of a knife to grind height to differ with holding cutter and rotary cutter.

Summary of the invention

The purpose of this utility model is to provide a kind of hand held sharpening apparatus, this hand held sharpening apparatus can replace staff directly to grab by cutter carrying out sharpening, and it is easy to use, can improve sharpening efficiency, improve the sharpening precision greatly, and can avoid of the injury of the high temperature of sharpening generation staff.

For reaching above-mentioned purpose, the utility model adopts following technical scheme, it is a kind of hand held sharpening apparatus, it comprises a testing stand, one locking seat, one fixed leg, one sleeve and a rotating seat, this fixed leg one end is fixedly connected should to lock seat, then fixedly connected this rotating seat of the other end, and this sleeve moving sleeve also can rotate around this fixed leg on this fixed leg, this locking seat includes a tool rest, one socket wall and one first limiting wall, this tool rest sidewall also is provided with and can cooperates the screw of screw with fixed cutting tool, this rotating seat includes one second limiting wall and one handle, this sleeve is positioned in the middle of this first limiting wall and this second limiting wall, this sleeve is confined to this first limiting wall and this second limiting wall and can freely rotates around this fixed leg just, this testing stand includes stock in addition, pillar and check-out console, fixedly connected and vertical this stock of this pillar, this check-out console then is movably arranged on this pillar, and vertical this check-out console of this pillar this socket wall this locking seat on is fixed this testing stand in this locking in thereby this stock can be enclosed within outward.

So, cutter is inserted in this tool rest, thereby utilize screw to be screwed together in the screw of this tool rest sidewall and fixedly secure this cutter, operator one holds above-mentioned this sleeve, the another hand only need rotate above-mentioned this rotating seat can carry out sharpening to each point of a knife of this cutter, and, only need above-mentioned this testing stand is socketed on the socket wall of above-mentioned this locking seat, slide on this testing stand check-out console and contact on this cutter point of a knife, can judge the height of each point of a knife by the conflict situation of observing each point of a knife of this cutter and this check-out console.

Owing to adopt technique scheme, the hand held sharpening apparatus that the utility model provides has such beneficial effect, promptly avoided of the injury of the high temperature of sharpening generation to staff, the handled easily person carries out sharpening to each point of a knife of cutter, can improve sharpening efficiency, simultaneously the sharpening precision of each point of a knife can be detected in real time, thereby the sharpening precision of cutter can be improved.

Fig. 2 is the schematic perspective view after the hand held sharpening apparatus of the utility model assembles cutter.

Fig. 3 is the schematic perspective view that the hand held sharpening apparatus of the utility model detects the cutter point of a knife.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Figure 1 shows that the schematic perspective view of the hand held sharpening apparatus of the utility model, wherein this hand held sharpening apparatus comprises a testing stand 100, one locking seat 200, one fixed leg, one sleeve 300 and a rotating seat 400, in present embodiment, this fixed leg is the strip cylinder, this fixed leg one end is shaped on this rotating seat 400, this sleeve 300 is coated on this fixed leg and can rotates around this fixed leg, this fixed leg other end outer surface then is provided with screw thread, and this locking seat 200 is provided with the screwed hole that can cooperate this screw thread, thereby this locking seat 200 is fixed on this fixed leg, this locking seat 200 includes a tool rest 210 in order to the plant cutter, one socket wall 220 and one first limiting wall 230, these tool rest 210 sidewalls also are provided with and can cooperate the screw 211 of screw with fixed cutting tool, in this real mode, this socket wall 220 is a circular arc, this rotating seat 400 includes one second limiting wall 410 and one handle 420, this sleeve 300 is positioned in the middle of this first limiting wall 230 and this second limiting wall 410, this sleeve 300 is confined to this first limiting wall 230 and this second limiting wall 410 and can freely rotates around this fixed leg just, in addition in present embodiment, this testing stand includes two stocks 110, the check-out console 130 of two pillars 120 and a disc-shape, these pillar 120 two ends are fixedly set on this stock 110, thereby 130 of this check-out consoles are provided with through hole corresponding to this two pillar 120 and can prolong this two pillar 120 and be free to slide, these two pillars, 120 vertical this check-out console 130 and this stocks 110, thus this stock 110 is fixed the annulus of this testing stand 100 on this locking seat 200 for being coated at above-mentioned this socket wall 220.
