Specific embodiment

Further to illustrate that the utility model is to reach the technological means and effect that predetermined purpose of utility model taken, Below in conjunction with attached drawing and preferred embodiment, to according to the utility model proposes specific embodiment, structure, feature and its effect, It is described in detail as after.

Fig. 1 show the structure diagram of the key of the utility model first embodiment.Fig. 2 show the quick-fried of Fig. 1 keys Fried figure.Fig. 3 show the sectional view of Fig. 1 keys.Fig. 4 show the enlarged drawing at the A of Fig. 3 keys.Fig. 1-Fig. 4 is referred to, this The key of embodiment, key is for opening Flat tumbler mortise lock or spring lock, including the body of rod 2, shank body 1 and fixing sleeve 3.

Shank body 1 is platy structure, and shank body 1 is equipped with limiting section 11, and shank body 1 also has keeps out with what 3 end face of fixing sleeve contacted Face 110, the thickness (X-direction) of shank body 1 is less than the thickness (X-direction) of the body of rod 2.

The body of rod 2 offers the tartar (figure does not regard) for unlocking, and the body of rod 2 is equipped with the auxiliary section 21 coordinated with limiting section 11, Limiting section 11 and the cooperation limitation shank body 1 of auxiliary section 21 are moved along 2 direction Y of the body of rod, and fixing sleeve 3 is located at limiting section 11 and auxiliary section Outside 21, and fixing sleeve 3 and limiting section 11 and/or the connection of auxiliary section 21 are fixed, 3 inner surface of fixing sleeve and limiting section 11 and auxiliary section 21 fittings, fixing sleeve 3 are made of rigid material.Fixing sleeve 3 is made admittedly after being set in outside limiting section 11 and auxiliary section 21 by squeezing Surely it covers 3 tops to contact with shank body 1, while makes between 3 upper opening of fixing sleeve is in 2 upper end end face of the body of rod and keeps out face 110, this Sample has been maintained for the position of fixing sleeve 3.Limiting section 11 is protrusion, and width of the limiting section 11 close to the position at 2 middle part of the body of rod is more than The width of position of the limiting section 11 far from 2 middle part of the body of rod.Limiting section 11 is trapezoidal platy structure.Auxiliary section 21 is and limiting section 11 corresponding notches
