When needing the mode of unblanking of " right side is drawn ", user can unload the 4th connector 250 and the second tooth bar 290, and unload the 3rd
Connector 240, now motion bar 270 can drive the first tooth bar 280 movable, and power is transferred to gear train by the first tooth bar 280
Part 260, until the first connector 220 is connected to the end of the inwall of the first spacing hole 2131, unlocking action stops.User can
With the element storage part that will unload, when wanting to change current mode of unblanking, push-pull mechanism can be re-assemblied as required
200, thus without again buying or exchange new push-pull lock 10.Further, since push-pull mechanism 200 can be avoided missing due to artificial
The reason sentenced causes push-pull lock 10 can not meet predetermined requirement and need to repeatedly exchange the problem of suitable push-pull lock 10, i.e. push-and-pull
The versatility of the push-pull mechanism 200 of lock 10 is preferable, such that it is able to facilitate the use of user.
Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, not to above-mentioned reality
The all possible combination of each technical characteristic executed in example is all described, but, as long as the combination of these technical characteristics is not deposited
In contradiction, all it is considered to be the scope that this specification is recorded.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed, but also
