Specific embodiment

Below by embodiment mode and become apparent from completely illustrating the utility model, but not therefore with reference to attached drawing The utility model is limited among the embodiment described range.

As shown in Figure 1, Figure 2 and Figure 3, the penknife of the utility model includes tool apron 3, hand handle 2, hand handle inner cover 1, Hand handle inner cover 1 is equipped with a threaded hole 11, and tool apron 3 is connected to the side of hand handle inner cover 1 by threaded hole 11, and hand handle 2 is connected to hand The opposite side of inner cover 1.The material of hand handle inner cover 1 is metal material, during people's rotary handle 2 so that drives hand handle inner cover 1 together Rotation, rotates so as to fulfill tool apron 3.The penknife of the utility model can directly carry out punching press thread to hand handle inner cover 1, without Secondary tapping, production cost is low, efficient.Meanwhile the punching press thread not sliding tooth not easy to wear of metal so that hand handle inner cover 1 can Reusability is hardly damaged, and greatly prolongs the service life of penknife.

As shown in Figure 2, Figure 3 and Figure 4, the outer rim of threaded hole 11 is equipped with notch 111.To 1 direct punching press spiral shell of hand handle inner cover Cutting is contributed to flow out during tooth, improves machining accuracy.

It can be in order to achieve the effect that be convenient to assemble between hand handle 2 and hand handle inner cover 1, between hand handle 2 and hand handle inner cover 1 Equipped with several clamping close devices, hand handle 2 is rotated by clamping close device drives hand handle inner cover 1 to rotate.The clamping close device includes down Hook part 12, card slot portion 21, overhead kick portion 12 are connected to hand handle inner cover 1, and card slot portion 21 is connected to one end of hand handle 2, and overhead kick portion 12 is embedding Set on card slot portion 21.So as to fulfill quick assembled handle 2 and hand handle inner cover 1, and assembly operation is convenient, light.

In order to achieve the effect that bonding strength after being assembled between enhancing hand handle 2 and hand handle inner cover 1, overhead kick portion 12 can include There are 121, two hooks 122 of a connection piece, two hooks 122 are connected to the both ends of connector 121, and card slot portion 21 includes One groove (not shown), two male members, two male members are connected to the internal face both ends of groove, and two hooks 122 divide It is not resisted against two male members.So that connected between hand handle 2 and hand handle inner cover 1 more securely, prevent hand handle 2 and hand handle inner cover 1 it Between generate sliding obscission when rotated, it is and simple in structure.Preferably, the quantity of clamping close device is three, and overhead kick portion 12 The outer peripheral edge of hand handle inner cover 1 can be located at.The material of hand handle 2 can be plastics, and production cost is low, and high in machining efficiency.

Penknife can also include hob head 4, rotaring wheeling base 5, and rotaring wheeling base 5 is also chafing dish, rotaring wheeling base 5 in industry term Hob head 4 and tool apron 3 are sheathed on, hob head 4 includes a hobboing cutter 41, a hobboing cutter gear 42, and one end of hobboing cutter 41 is connected to Hobboing cutter gear 42, and gear is connected to rotaring wheeling base 5 and tool apron 3 respectively at the both ends of hobboing cutter gear 42.Hand handle 2 will pass through hand when rotating Tool apron 3 is driven to rotate inner cover 1 so that hobboing cutter gear 42 itself can also rotate, meanwhile, pass through 5 hobboing cutter gear of rotaring wheeling base 42 rotate round the surrounding of tool apron 3, are revolved round the sun by rotaring wheeling base 5 and 3 hobboing cutter 41 of tool apron and rotation, so as to fulfill penknife Pen is cut, it is simple and reliable for structure.
