According to the protection structure provided by the embodiment of the invention, the guide hole which is obliquely arranged in the length direction is arranged on the driven piece, and the movable piece and the fixed piece are arranged, so that when the driving force of the driving piece exceeds the limit value, the movable piece can move towards the direction of the limit surface of the fixed piece under the guide effect of the guide hole until the movable piece abuts against the limit surface, and the driving piece stops driving movement. In the tool to lock, the keeper board can be the driving piece, and the inside spare part of being connected with the keeper board drive of tool to lock is by the driving piece, and when the tool to lock that is in the block state was unblanked by force, the keeper board moved the moving part under the guide effect of guiding hole, supported in the spacing face of mounting to make the keeper board stop the drive motion, avoided the inside spare part of tool to lock impaired.
In an alternative embodiment, see fig. 1, the mobile element 1 may have a low top end; the fixed part 2 can be located at one side of the lower top end, so that when the driving force of the driving part 10 does not exceed the limit value, the movable part 1 can drive the driven part 20 to move normally through the fixed part 2 through the guide hole 201. That is to say, the setting position of mounting 2 should not cause the interference to the normal work of tool to lock, and the setting position of mounting 2 can not influence the removal of keeper board promptly, and when the drive power of keeper board did not exceed the limit value, moving part 1 can not be guided by guiding hole 201 and move to spacing face 211, but is connected with the drive plate through guiding hole 201, realizes the driving action of keeper board to the driving piece, convenient to use.
