Description
Technical field
The invention belongs to study article technical field more particularly to a kind of safe technology scissors.
Background technique
Paper-cut can be very good to temper the imagination and manipulative ability of children, but traditional scissors has sharp scissors knife
Sword and scissors point of a knife have biggish risk, are not suitable for children and use.Currently, main for the Safety scissors of children's design
There are two types of forms: one is plastic safety scissors, this Safety scissors are made of duroplasts, can prevent children from coming to harm, but
It is that it is not sharp enough, children's strength is relatively small, and such Safety scissors cannot be used to cut harder cardboard；Another kind is by scissors
Point of a knife fall it is blunt or encapsulation, can prevent scissors point of a knife from stabbing children, but two blades of this scissors can angle of release it is larger,
It is generally existing that the finger of children is easy to cut the problem of hurting.
Summary of the invention
In order to solve the above problem, the present invention proposes a kind of safe technology scissors, with stronger shear ability, and can prevent
Only children are stabbed and are cut wound.
In order to achieve the above object, the present invention is resolved using following technical scheme.
A kind of safe technology scissors, comprising: two shear blades and two telescoping handles；One end of the shear blade is scissors
Point, the other end are scissors tail, are provided with main hinge hole in the middle part of the shear blade, the inside edge of the scissors point is provided with knife
Sword, outer edge are provided with the first secondary hinge hole, the second secondary hinge hole are provided on the scissors tail, and two shear blades pass through
The main hinge hole is hinged；One end of two telescoping handles respectively with the first secondary hinge hole on two shear blades
It is hinged, the other end of two telescoping handles is hinged with the second secondary hinge hole on two shear blades respectively.
Safe technology scissors according to the present invention, the main hinge hole on two shear blades is hinged by main articulated shaft, and two
Shear blade can be relatively rotated around main articulated shaft, complete the shearing to paper, the inside edge setting of scissors point by two scissors points
There is blade, can make safe technology scissors that there is stronger shear ability；The hinge joint of two shear blades is located at two flexible hands
Between handle, the partial-length of the jagged telescoping handle out of scissors can be made shorter, children can be prevented to be hurt by scissors spine；Telescoping handle
The first secondary hinge hole that one end is arranged with scissors point outer edge is hinged, and second on the other end and shear blade of telescoping handle is secondary
Hinge hole is hinged, and the open-angle of two scissors points can be limited in a lesser angle by telescoping handle, both guaranteed
Paper can protrude between the blade of two scissors points, smoothly complete shearing, and guarantee that the finger of children cannot protrude into two scissors
Between the blade of point, the finger that can avoid children is cut wound.Safe technology scissors of the invention makes safety by the way that blade is arranged
Artistical shears have stronger shear ability, and children can easily shear harder cardboard with it；The jagged telescoping handle out of scissors
Partial-length is shorter, and children can be prevented to be hurt by scissors spine；The expansible angle of two scissors points is limited by telescoping handle,
Prevent the finger of children from protruding between the blade of two scissors points, the finger that can avoid children is cut wound.
Preferably, the telescoping handle includes: guide cylinder and guide rod；One end of the guide cylinder is provided with first
Hinge seat, the shear blade are hinged by the first secondary hinge hole with the first hinge seat；One end of the guide rod is protruded into
In the guide cylinder, the other end is provided with articulated joint, and the scissors tail passes through the hinge on the second secondary hinge hole and the guide rod
Connector is hinged.
Safe technology scissors according to the present invention, telescoping handle is by guide cylinder and guide post group at one end of guide cylinder is set
Be equipped with first hinge seat, guide cylinder is hinged by first hinge seat and the on shear blade first secondary hinge hole, guide cylinder it is another
One end is provided with blind hole, track of this blind hole as guide rod；One end of guide rod is secondary by second in articulated joint and shear blade
Hinge hole is hinged, and the other end of guide rod protrudes into the blind hole track of guide cylinder, and guide rod is slidably connected with guide cylinder.By two
A telescoping handle is close, and guide cylinder and scissors point relatively rotate around the first secondary hinge hole, and guide rod and scissors tail are around second
Secondary hinge hole relatively rotates, and two guide rods drive two scissors tails close to each other, guide rod along guide cylinder blind hole track to
It skids off outside；When two scissors tails are close to each other, two shear blades relatively rotate around main hinge hole, and then make two scissors points
Close to each other, final two scissors points complete the shearing to paper.Two telescoping handles are separate, and two shear blades are around main hinge
Hole relatively rotates, and two scissors tails and two scissors points are respectively further from, and guide rod slides into along the blind hole track of guide cylinder, works as guiding
When bar withstands the bottom end of blind hole, two shear blades will be no longer able to turn, and two scissors points also will not be further away from passing through telescoping handle
The opening angle that two scissors points can be limited prevents the finger of children from protruding between the blade of two scissors points, avoids children's
Finger is cut wound, in addition, telescoping handle being closer from scissors point, can be improved the control precision of scissors, be conducive to children's
Paper-cut operation.
Preferably, being provided with becket on the guide cylinder.
Safe technology scissors according to the present invention can be opened two telescoping handles by bracelet, and then driven two and cut
Point of a knife opens, and is easy to use.
Preferably, being provided with tension spring between the guide cylinder and the guide rod.
Safe technology scissors according to the present invention is equipped with tension spring in the blind hole track of guide cylinder between guide rod,
Tension spring can make two scissors points be in normally open；After paper-cut finishes release telescoping handle, guide rod is pulled in automatically and is led by tension spring
To cylinder, two scissors points are automatic to be opened, and is easy to use.
Preferably, the end angle angle of the scissors point is more than or equal to 45 °.
The end angle angle of scissors point is set greater than equal to 45 °, can reduce and cut by safe technology scissors according to the present invention
The sharpness of point of a knife prevents scissors point from stabbing children.
