Buffer spring is cased on column, electric screwdriver is mounted in L-shaped installing plate.Above-mentioned screw is screwed into the buffer spring in device, uses
It is compensated in the locking process for being screwed into device to screw.
Above-mentioned screw is screwed into device, for drive electric screwdriver lift driving mechanism (including lifting slider, L-shaped peace
Loading board), driving electric screwdriver declines, and is impulse stroke, and drives electric screwdriver to rise and reset, be then non-working line
Journey, in this way, half action made by driving mechanism is impulse stroke, the other half action is non-impulse stroke, not only causes the energy
Waste, moreover, working efficiency cannot improve.Above-mentioned impulse stroke and inoperative stroke are collectively referred to as the two-way row of driving mechanism
Journey.
Invention content
Technical problem solved by the invention：How the utilization of the two-way travel of the driving mechanism that is equipped with screw gun is improved
Rate, to improve the working efficiency of screw gun lock screw.
In order to solve the above technical problems, the present invention provides the following technical solutions：A kind of bidirectional locking mechanism, including be mounted on
Two locking tools in driving mechanism, moving direction when two locking tools work are opposite.
According to the above technical scheme, driving mechanism moves ahead, and the first locking tool in two locking tools is driven to move ahead, and first
Locking tool locking is located at the part in front of it；Driving mechanism, which retreats, to be resetted, and the second locking work in two locking tools is driven
Row after tool, moving direction when being worked due to two locking tools on the contrary, driving mechanism drives row after the second locking tool, for
It is then forward for second locking tool, the locking of the second locking tool is located at the part in front of it.In this way, the advance of driving mechanism
And retrogressing, it can drive corresponding locking tool to work, moving forward and backward for driving mechanism is impulse stroke, destroked wave
Take.
In above-mentioned technical proposal, locking tool can be screw gun, and the part that locking tool is locked mutually should be screw.
