Description

Letter opener

Technical field

The utility model relates to a kind of letter opener.

Background technology

Usually, people after receiving mail, opening encapsulation the method for envelope mainly contain three kinds: the one, directly tear the envelope limit off with hand; The 2nd, cut off the envelope limit with scissors; The 3rd, cut off one jiao in envelope with scissors earlier, open envelope with the envelope cutter then.Above-mentioned three kinds of methods of opening envelopes have all been destroyed the integrality of envelope to some extent, have made paper scrap rubbish, and use convenient inadequately.

Summary of the invention

The purpose of this utility model is can keep the envelope integrality in order to provide a kind of, and uses letter opener more easily.

Letter opener of the present utility model comprises blade, blade holder and bearing.Blade holder is installed in upper surface of support; Upper surface of support has a cutter groove, and the blade that is installed on the blade holder can stretch in the inner chamber of bearing by the cutter groove.

After adopting said structure, people only need letter opener is enclosed within envelope on one side when opening envelope, one draw gently then, can open a neat otch on the upper strata of envelope, take out mail, and have kept the integrality of envelope, operate very easy.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Embodiment one

Letter opener comprises blade 1 as shown in Figures 1 to 4, blade holder 11 and bearing 2, and bearing 2 is a shape of a hoof elastic pressuring plate.Blade holder 11 is fixed on bearing 2 upper surfaces; Bearing 2 upper surfaces have a cutter groove 22, and the blade 1 that is installed on the blade holder 11 can stretch in the inner chamber 23 of bearing 2 by cutter groove 22; Banking stop 3 is fixed on inner chamber 23 diapires.

During use, one side at envelope puts letter opener, light push type broach horse 11, blade 1 is moved down be pressed on the envelope limit, this moment, banking stop 3 limited further moving down of blade 1, when with the hand propelled letter opener when move on the envelope limit, blade 1 can cut the upper strata of envelope one neat otch, thereby reach the purpose of opening envelope, kept the integrality of envelope again.

Embodiment two

Fig. 5 and Fig. 6 are the another kind of specific embodiment of the present utility model, and the blade holder 11 of this letter opener is fixed on bearing 2 upper surfaces by spring 5.When depressing blade holder 11, spring 5 is followed contraction, and when spring 5 was contracted to maximum, the function of spring 5 was suitable with banking stop 3.Like this, Fig. 5 and letter opener shown in Figure 6 can reach the purpose of opening envelope equally, and the same integrality that can keep envelope.

Embodiment three

The utility model letter opener can also have following improvement: have above the blade holder 11 a cutter groove 22 ', there is a parbuckle screw 12 in the front, blade 1 by parbuckle screw be fixed on cutter groove 22 ' in.Like this, different-thickness according to envelope, people can adjust the built-in length of blade 1 at inner chamber 23 by parbuckle screw 12, can gently be pressed in above the envelope with blade 1 and to be as the criterion, letter opener is enclosed within on the envelope limit then, one draw gently, can on envelope, open a neat otch equally, and can keep the integrality of envelope.

In addition, the face shaping of blade 1 is designed to trapezoidal, blade 1 is contacted with becoming point above the envelope, more help to cut envelope.One little ring 6 is arranged on the letter opener, make it can be made into key chain, conveniently carry.
