Description

Daily technology jack knife

Technical field

The utility model relates to a kind of cutter, specifically is by cutter head, handle of a knife and latching device, the daily technology jack knife that cutter head connects together and forms with handle of a knife rotationally.

Background technology

Jack knife normally is made up of the cutter head and the handle of a knife that have point of a knife and circular arc cutter tail, handle of a knife is made up of back of the body bar and two clamping plate, two clamping plate avris clip back of the body bar, and an end is clamped the circular arc cutter tail of cutter head, and by pinning cutter head are connected together with handle of a knife rotationally.Avris back of the body bar front end is provided with eave tile, and the circular arc cutter trailing edge of cutter head is provided with complementary notch, constitutes latching device.When jack knife was opened, the eave tile of the back of the body on the bar colluded just in breach, prevented from that the cutter head accident from closing up to hurt hand.The shortcoming of the jack knife of this structure is that handle of a knife is not an integrative-structure, assembles cumbersomely, and product specification is not high yet.

Summary of the invention

The purpose of this utility model is to provide a kind of daily technology jack knife simple in structure, easy to assembly for overcoming the deficiencies in the prior art.

For achieving the above object, the technical scheme that daily technology jack knife of the present utility model is adopted is as follows: a kind of daily technology jack knife, comprise handle of a knife and cutter head and latching device, cutter head has point of a knife and circular arc cutter tail, handle of a knife has the flat bit cavity volume, the afterbody of described cutter head is rotatably connected on the end of cutter head cavity volume by pin, the circular arc cutter trailing edge of cutter head is provided with shackle notch, it is characterized in that: described handle of a knife be the long banding of a side close have a flat bit cavity volume member, under the jack knife open mode, the position of the corresponding cutter head afterbody in both sides shackle notch is arranged with the saturating groove of the arc that communicates with the cutter head cavity volume before and after the described handle of a knife, be equipped with the U-shaped lock ring movingly in the saturating groove of described arc, the U-shaped leading section of described U-shaped lock ring drops in the saturating groove of arc, and the both sides, front and back that two tail ends are separately fixed at handle of a knife constitute described latching device.

Because the handle of a knife of daily technology jack knife of the present utility model is an overall structure, member is less, and therefore the more traditional jack knife of assembling is convenient, and outward appearance also has more integrated beauty, can improve the class of product.
