Two side plates 3.And by using above structure, it can avoid blade 1 and effectively prolong so as to reduce frictional force with handle of a knife CONTACT WITH FRICTION
Long blade 1, the service life of handle of a knife.Wherein, the first bearing device includes being sequentially arranged at the along close to 1 direction of blade
First bearing pedestal 71, first bearing 72 in 2 groove of side plate；The second bearing device includes along close to 1 side of blade
To be sequentially arranged in 3 groove of the second side plate second bearing pedestal, second bearing；The first bearing 72, second bearing are equal
Including retainer, circumferential arrangement on retainer and can relative to retainer rotate several balls.The main shaft mother screw 81
Be arranged in first bearing pedestal 71, first bearing 72, second bearing pedestal, in second bearing.
Preferably, it has been screwed belt clamp 91 on the handle of a knife, to be convenient to jack knife being fixed on belt.Its
In, several threaded holes to match with screw are provided on the handle of a knife.And by using above structure, it can be convenient to adjust
The position of belt clamp 91.
Preferably, the handle of a knife set intracavitary be also movably installed with for by blade part 12 toward setting pushing away for pushing tow outside chamber
Bar 92；Spring 93 is installed, the spring 93 promotes push rod 92 to be set toward separate for providing between the push rod 92 and handle of a knife
The elastic stress of chamber opening direction movement；The push rod 92 stretches out on one end outside handle of a knife and is provided with lever.And by using
Above structure, can by pressing push rod 92, so as to using push rod 92 by blade part 12 toward setting pushing tow outside chamber, to more just
Just, laborsaving, and when discharging push rod 92, push rod 92 is under the elastic force effect of spring 93 toward far from setting the movement of chamber opening direction.
It will be apparent to those skilled in the art that technical solution that can be as described above and design, make various other
Corresponding change and deformation, and all these changes and deformation should all belong to the protection domain of the claims in the present invention
Within.
