Description

Reciprocating cutter head

Technical Field

The utility model relates to a reciprocating type tool bit especially relates to a reciprocating type tool bit for clean nursing of individual.

Background

The reciprocating type tool bit on the existing market generally comprises a movable tool and an outer tool net, the outer tool net, namely an outer net cover, generally keeps still, the movable tool bit can reciprocate relative to the outer tool net, for the tool bit, whether shaving is thorough or not is mainly the shaving cleanliness, the shaving comfort level is high, the service life of equipment, particularly the tool bit, the outer tool net is required to be as thin as possible, and the thin outer tool net is poor in supporting force, easy to break and short in service life. Therefore, the general outer knife net can only be made to be 15 wires or more than 15 wires in order to take the supporting force into consideration.

Disclosure of Invention

An object of the utility model is to provide a reciprocating type tool bit that stationary knife is thin and supporting stability is high to the defect that prior art exists.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a reciprocating type tool bit, includes knife rest, the outer sword net of connection on the knife rest, the sword that contacts with outer sword net bottom surface relative slip ground under reciprocating drive mechanism drives, outer sword net integrated into one piece and transversal personally submit the curve, outer sword net includes that the cross-section is curved main knife face, the skew knife face of bending type downwards from two long limits of the knife face of autonomic knife face respectively in length place orientation promptly, main knife face and skew knife face on be equipped with skin-friendly groove district, it has a plurality of palpus grooves of advancing to distribute on skin-friendly groove district, outer sword on be equipped with the protruding muscle that the enhancement supporting was used, protruding muscle keep away from on outer sword net and advance palpus groove.

As an improvement: the left side and the right side of the skin-friendly groove area of the main knife surface are provided with convex ribs.

As an improvement: the convex ribs are arranged on the periphery of the skin-friendly groove area on the outer knife net in a surrounding mode.

As an improvement: the convex ribs on the main cutter surface are abutted against the left and right inner edges of the cutter frame, so that the connecting seams between the outer cutter mesh and the left and right sides of the cutter frame are sealed.

As an improvement: the outer cutter net also comprises two pressure-receiving surfaces which are formed by bending the two long edges of the side inclined cutter surface downwards and outwards in a tilted mode, and the free lower ends of the two pressure-receiving surfaces are clamped into the cutter frame and are not exposed.

As an improvement: the bottom of the knife rest is also inserted with a buckling device for fixing the outer knife net on the knife rest, the buckling device comprises a bridging body which is arranged along the width direction of the bottom of the knife rest in a front-back crossing manner and is connected to the bottom of the knife rest in a limiting manner, two 7-shaped hook bodies which extend upwards from the front end and the rear end of the bridging body to form the two 7-shaped hook bodies, and the free ends of the two 7-shaped hook bodies are arranged in opposite directions and are buckled on two pressing surfaces of the outer knife net respectively.

The utility model discloses a reciprocating type tool bit keeps away from the protruding muscle in close skin groove district and strengthens outer sword net supporting for whole outer stationary knife net is thin to have sufficient holding power again, and the sharpness of tool bit is higher, can cut must the root, shaves more totally, and stability is very good. The curve type integrally formed outer cutter net has higher shaving comfort level, no edges and corners on the surface and no burrs, the beard feeding groove can be arranged in a large area, and the beard feeding amount at one time is large, so that the shaving efficiency is improved.

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.

Detailed Description

As shown in fig. 1 and 2, the utility model discloses an embodiment of reciprocating type tool bit, including knife rest 3, joint outer cutter net 1 on knife rest 3, under the drive of reciprocating drive mechanism with outer cutter net 1 under bottom surface relative slip ground contact move the sword 2, outer cutter net 1 integrated into one piece and transversal personally submit the curve, outer cutter net includes that the cross-section is curved main cutting surface 11, respectively from the both sides inclined cutting surface 12 that the two long limits of knife face 11 adduction bending type become downwards, from the two long limits of side inclined cutting surface 12 stick up two pressure surfaces 15 that the bending type formed downwards outwards in length place orientation, two free lower extreme cards that connect pressure surfaces 15 are gone into in the knife rest and are not exposed. The main blade surface 11 and the inclined blade surfaces 12 on the two sides are provided with skin-friendly groove areas, a plurality of beard feeding grooves 13 are distributed on the skin-friendly groove areas, convex ribs 14 are arranged on the outer blade net along the periphery of the skin-friendly groove areas, and the convex ribs 14 are far away from the beard feeding grooves 13. The ribs 14 are continuously provided on the side rake face 12, but may be intermittently provided.

The convex ribs of the embodiment surround the skin-friendly groove area where the beard groove is located, so that the whole outer fixed cutter mesh has enough supporting force even if the thickness is less than 10 threads or even 5 to 6 threads, the sharpness of the cutter head is higher, the beard can be cut to the root, the shaving is cleaner, and the stability is very good.

In the embodiment, the circular beard feeding grooves are distributed on the main blade surface 11, the long-hole type large-opening beard feeding grooves are arranged on the inclined blade surfaces 12 on two sides, the arrangement design of the beard feeding grooves is more reasonable, shaving is more comfortable, and the problems of beard tearing, meat clamping, difficulty in feeding long beard and the like are effectively solved. The ribs 14 on the main cutting surface 11 abut the left and right inner edges of the cutter holder 3, thereby closing the joint between the outer cutter mesh 1 and the left and right sides of the cutter holder 3. Prevent hair from entering the connecting seam, ensure the sanitation and cleanness of the side part of the knife rest and ensure the operation stability of the knife head.

For the stability of being connected of improving outer cutter mesh, guarantee that the edge of outer cutter mesh does not expose on the tool bit, guarantee safety, this embodiment knife rest 3's bottom is still inserted and is equipped with and be used for fixing outer cutter mesh 1 and withhold device 4 on knife rest 3, withhold the device include along knife rest bottom width direction around stride establish and spacing connection at the cross-over connection body 41 of knife rest bottom, upwards extend from the front and back both ends of cross-over connection body 41 and form two "7" type clasp bodies 42, the free end of two "7" type clasp bodies 42 sets up in opposite directions and withhold respectively on two of outer cutter mesh 1 connect the pressure face 15, connect the cooperation department of two "7" type clasp bodies 42 on the pressure face 15 and keep away from the protruding muscle, avoid the protrusion of protruding muscle to set up the influence and withhold the compactness. The buckling device limited at the bottom of the knife rest 3 can always keep the state of pressing the outer fixed knife net on the knife rest, the situation that the outer knife net runs out of the knife rest due to the fact that the outer force is pushed and warped is avoided, the outer knife net can be stably fixed on the knife rest due to the arrangement of the buckling device, and stable matching of the outer knife net and the movable knife is guaranteed.

Although the present invention has been described with reference to the specific embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention.
