Description
Technical field
The present invention relates to a kind of pocket knife, particularly a kind of student's pocket knife.
Background technology
In general, typically seen on the market student's pocket knife is hinged one piece of blade for simple plastics sheath, this
Knife back extruding plastics sheath causes the sheath will soon to ftracture to pocket knife in use, leads to not use, and can not be more
Part is changed, can only be thrown away, greatly waste resource, and plastics are reluctant refuse harm environment.
The content of the invention
Not environmentally durable to solve the problems, such as above-mentioned pocket knife, the present invention provides a kind of environmentally friendly pocket knife.
The technical solution adopted for the present invention to solve the technical problems is：A kind of environmentally friendly pocket knife, including sheath, rotating shaft, knife
Piece, the end of sheath is provided with through hole, and in through hole, blade is hinged in rotating shaft for rotating shaft, it is characterised in that：Rotating shaft is by screw and spiral shell
There is a screw thread mother's composition, the upper end of the screw, middle non-threaded, and the bottom of screw is hexagonal head, hexagonal head insertion
1mm in sheath；The rotating shaft is provided with pad, and pad is between blade and sheath.
Further, the pad is hard alloy, and the sheath is duroplasts.
Further, the length of the blade is the half of sheath.
Further, the centre of the sheath is provided with gap, can open the blade packed up.
The beneficial effects of the invention are as follows：The present invention can protect sheath with pad when in use, extend the use longevity of pocket knife
Life, and quick-wear part is replaceable, process is simple, with low cost, durable environmental protection.
Brief description of the drawings
Fig. 1 is a kind of structural representation of environmentally friendly pocket knife；
Fig. 2 is a kind of side view schematic diagram of environmentally friendly pocket knife.
In figure：Sheath 1, rotating shaft 2, blade 3, pad 4, screw 21, nut 22.
Specific embodiment
To make technical scheme become more apparent, specific embodiment is made into one to the present invention below in conjunction with the accompanying drawings
Step explanation.
As shown in Figure 1-2, a kind of environmentally friendly pocket knife, including sheath 1, rotating shaft 2, blade 3, the end of sheath 1 are provided with through hole, turn
In through hole, blade 3 is hinged in rotating shaft 2 axle 2, it is characterised in that：Rotating shaft 2 is made up of screw 21 and nut 22, the screw
There is a screw thread 21 upper end, middle non-threaded, and the bottom of screw 21 is hexagonal head, 1mm in hexagonal head insertion sheath 1；
The rotating shaft 2 is provided with pad 4, and pad 4 is between blade 3 and sheath 1.
Further, the pad 4 is hard alloy, and the sheath 1 is duroplasts.
Further, the length of the blade 3 is the half of sheath 1.
Further, the centre of the sheath 1 is provided with gap, can open the blade packed up.
When using, blade 3 is opened from the gap of sheath 1, the knife back of blade 3 is pressed on pad 4, one end connection rotating shaft of pad 4 is consolidated
Fixed, the pressure of the knife back is born in one end, plays a part of to protect sheath 1；The unique Design of length of blade can be effectively reduced cuts lead
When torque；If blade 3 or pad 4 are damaged or corrosion, the nut 22 of rotating shaft 2 can be unloaded, more allowing blade replacement 3 or pad 4.
The present invention can protect sheath with pad, extend the service life of pocket knife, and quick-wear part is replaceable, technique
Simply, it is with low cost, durable environmental protection.
Above technical scheme is only the preferred embodiments of the present invention, but protection scope of the present invention is not limited thereto, and is appointed
How those familiar with the art is on the basis of the technology of the present invention, the change not being readily available by creative work
The technical scheme changed or replace, should all be included within the scope of the present invention.
