End region and the anti-plectrum blunt ends under shutdown state, be connected to baffle together.Preferably, the anti-plectrum is also set
There is curved end, the curved end is opposite with the planar ends and adjacent with the blunt ends, and the curved end and the latch bolt
Plane area it is adjacent；The design of curved end is that the anti-plectrum is avoided to block baffle in rotation.Turn in view of adapting to anti-plectrum
The technical issues of moving to cooperate block end to use, it is preferred that the anti-plectrum is also provided with escape groove, and the escape groove is set to
Between the block end and the planar ends, the escape groove when the anti-plectrum is struck for the block end for providing
Rotation space so that block end block in outside.Preferably, the escape groove for being when the anti-plectrum is struck
The block end provides rotation space so that block end block is in the lock housing.Alternatively, the escape groove is used for described
Rotation space is provided so that block end block is in the lock panel when anti-plectrum is struck for the block end.Preferably
, the escape groove has the section of rectangle, round rectangle or part circular.Thus anti-dial when the anti-plectrum is struck
Piece can rotate a small distance, and block end can rotate with it at this time, so as to securely block in external such as lock housing,
On lock panel or baffle；If not designing escape groove, when the anti-plectrum is struck, anti-plectrum can only lead in situ
It crosses block end and is directly held in outside, be possible to friction can occur and slide because stress is excessive in this case when manufacturing experimently test
Out the problem of.
The technical issues of solving security performance in view of optimization, it is preferred that the latch bolt has opposite both ends, each
The end is adjacent with the plane area.Wherein, the both ends include upper end and lower end.Preferably, the end tool
There are plane or inclined plane shape.Preferably, the two end symmetric setting.End it is either flat or it is oblique, do not affect anti-
The connection and use of plectrum.The symmetrically arranged design scheme in both ends can cooperate the embodiment of the following two anti-plectrums to make
With, can also the only one anti-plectrum of setting, still, in trial-production test, the effect of a pair of anti-plectrum is preferable.It is preferred that
