Specific embodiment
With reference to the accompanying drawing and specific embodiment the present invention will be described in detail:
Fig. 1 is one embodiment of the invention positive structure schematic, and Fig. 2 is one embodiment of the invention sectional perspective structural schematic diagram,
Make part to shell 1 in two width figures to cut off, in order to see the related knot of circuit protecting switch 6 and mechanical lock mechanism clearly
Structure, and the upper cover of supported lid-turning 2 is concealed, to see mechanical lock mechanism clearly.
One embodiment of the invention provides the double protection structures on a kind of grass dressing machine of front replacement blade assembly, comb grass
1 front of casing body is equipped with opening, and opening is equipped with supported lid-turning 2, and mechanical caging machine is equipped between supported lid-turning 2 and shell 1
Structure is additionally provided with the circuit protecting switch 6 triggered by mechanical lock mechanism when locking or unlocking in shell 1.
In the grass dressing machine of front replacement blade assembly, blade assembly is to be packed into shell 1 by the positive opening of shell 1
In, then assist completing the fixation of blade assembly by supported lid-turning 2, therefore mechanical lock is equipped between supported lid-turning 2 and shell 1
Mechanism is determined, so as to fixed blade component.When mechanical lock mechanism locks, circuit protecting switch 6 is in closed state, comb grass
Machine is in safety state to be launched.When needing replacing blade assembly, need to remove supported lid-turning 2, expose blade assembly, then from
1 opening of shell takes out blade assembly, at this point, mechanical lock mechanism is in the unlocked state, circuit protecting switch 6 is also at disconnected
Open state, grass dressing machine are in off-position, personnel when replacing blade assembly, without having to worry about other people maloperations or other reasons and
Blade assembly is caused to be jerked, it is highly-safe.
In a specific embodiment, circuit protecting switch 6 is touch switch, including what can be triggered by mechanical lock mechanism
Drive rod.
In a specific embodiment, circuit protecting switch 6 accesses protection circuit with normally open.Circuit protecting switch 6 is
Normally open, only when mechanical lock mechanism locks, circuit protecting switch 6 is just closed, and grass dressing machine is in safety shape to be launched
State.
In a specific embodiment, mechanical lock mechanism makes to protect closing of circuit in lock timing trigger circuit protective switch 6.
Mechanical lock mechanism is in contact in locking process with the drive rod of circuit protecting switch 6, so that circuit protecting switch 6 be made to close
It closes.
In a specific embodiment, mechanical lock mechanism includes opening on 2 side wall of supported lid-turning, corresponds on shell 1
