Abstract

The utility model relates to a safety envelope operer used to open the daily envelope conveniently. The apparatus comprises a crust, a blade, and a spring, wherein, the crust comprises a small cover board, a big cover board, and a moterboard, the middle of the big cover board is made into a concave shape, the moterboar has a guide groove on the middle of the upper end, and a U shape spring is arranged on the position perpendicular to the guide groove of the ower end, the U shape spring clamps the blade, the end of the blade has a round hole and is connected with the moterboard, the other end of the blade has the cutting edges on right and left, which both acute angles and bilaterally symmetry, the blade backs to the normal position when nonuse, and can moves around the round hole in the guide groove when use, the more angle moved, the more resistance caused by the U shape spring, which forces the sharp corner of the blade to insert into the envelope and open the envelope. The utility model has the advantages that: the utility model can open any side of the envelope, need no spacing in the sealing place, has a simple structure, design novelly, and is safety reliability.

Description

The secure envelope opener

Affiliated technical field

The utility model relates to a kind of device that can open daily mail easily, refers to a kind of secure envelope opener especially.

Background technology

At present, the blade of the better simply letter opener of known several classes is exposed, often only when the sealing part of envelope has the space, just can open, or parts make manufacturing cost higher too much, might produce envelope or the situations such as dangerous or use inconvenience of tearing.

Summary of the invention

In order to overcome above-mentioned weak point, the purpose of this utility model aims to provide a kind of letter opener, and it can open any one side of envelope, and sealing part that again need not envelope has the space.

The technical scheme that its technical problem that solves the utility model adopts is: this device has shell, blade and spring are formed, this shell is by minor flaps, large cover and base plate are formed, in the middle of large cover, make recessed circle, suitable thumb is being held, in the middle of the base plate upper end, gathering sill is arranged, the upright position of lower end and gathering sill is provided with U type spring, U type spring is clamped blade, blade one end has a small sircle hole to link to each other with base plate, the left side of the other end, all put the first edge on a knife or a pair of scissors in right both sides, and two angles remain sharply, left-right symmetry, envelope can pass through blade from both sides, when not using, blade is returned to the normal position, and when using, blade can rotate around an end circular hole in gathering sill, when blade rotation, U type spring can stop blade rotation, and the blade rotation angle is big more, and the resistance that U type spring produces is just big more, correspondingly masterpiece is used for blade and removes to cut envelope flap, if it is thick more to make the paper of envelope, the pressure that then needs is just big more, can force the wedge angle of blade to inject envelope, in case blade has injected envelope, along with moving of opener, the edge of a knife is that natural energy is opened along envelope, one side and can select any of envelope to open.

The beneficial effects of the utility model are: can open any one side of envelope, sealing part that need not envelope has the space, and is simple in structure, and modern design is safe and reliable.

The specific embodiment

See also accompanying drawing 1,2,3,4, shown in 5, the utility model has shell, blade 4 and spring are formed, this shell is by minor flaps 2, large cover 3 and base plate 1 are formed, in the middle of large cover 3, make recessed circle, suitable thumb is being held, gathering sill 6 is arranged in the middle of base plate 1 upper end, the upright position of lower end and gathering sill 6 is provided with U type spring 5, U type spring 5 is clamped blade 4, blade 4-end has a small sircle hole to link to each other with base plate 1, the left side of the other end, all put the first edge on a knife or a pair of scissors in right both sides, and two angles remain sharply, left-right symmetry, envelope can pass through blade from both sides, when not using, blade 4 is returned to the normal position, when using, blade 4 can rotate around an end circular hole in gathering sill 6, and when blade 4 rotated, U type spring 5 can stop blade 4 to rotate, blade 4 rotational angles are big more, the resistance that U type spring 5 produces is just big more, correspondingly masterpiece is used for blade 4 and removes to cut envelope flap, if it is thick more to make the paper of envelope, the pressure that then needs is just big more, can force the wedge angle of blade 4 to inject envelope, in case blade 4 has injected envelope, along with moving of opener, the edge of a knife is that natural energy is opened along envelope, one side and can select any of envelope to open.All there is the cutting edge of a knife or a sword mouth on the blade both sides, and left-right symmetry makes it to be beneficial to the situation of opening with the left hand or the right hand.

Claims

1, a kind of secure envelope opener, this device has shell, blade and spring, it is characterized in that: shell is by minor flaps, large cover and base plate, in the middle of large cover, make recessed circle, in the middle of the base plate upper end, have gathering sill, the upright position of lower end and gathering sill that U type spring is set, U type spring is clamped blade, blade one end has a small sircle hole to link to each other with base plate, the left side of the other end, all put the first edge on a knife or a pair of scissors in right both sides, and two angles are sharp-pointed, left-right symmetry, when not using, blade is returned to the normal position, when using, blade can rotate around an end circular hole in gathering sill, rotational angle is big more, and the resistance that U type spring produces is just big more, can force the wedge angle of blade to inject envelope.
