With the direction of connecting axle horizontal vertical on be at least provided with two-layer travel switch, every layer of travel switch is at least provided with two travel switches between middle support plate and left supported plate, right supported plate.
Be separated by between two-layer travel switch and limiting plate is installed, for limiting the position of adjacent two layers travel switch.
Described connecting axle two ends adopt the mode be threaded that the direction of left and right support plate to middle support plate is clamped and fixed.
Described travel switch is provided with two pair of wire connection terminals, for being connected with external power cord at the other end place relative with being provided with button one end.
On the basis of technique scheme, as further improvement of the utility model:
Described left and right support plate is right-angled trapezium, left and right support plate right-angled trapezium long parallel edges by acute angle one end in opposite directions bending be a bent plate for being connected with electrical equipment, bent plate has two connecting holes.
Described middle support plate is rectangle, stretches out a bending plate, bending plate has a through hole outside the place of end being in the same way provided with bent plate with left and right support plate.
The process of the utility model specific works:
The utility model is connected on electrical equipment by the bending plate of the bent plate on left and right support plate and middle support plate, utilize the output of turning cylinder to drive and rotate pressing plate rotation, one end extruding pressing plate of the rotation pressing plate length rotated moves to the direction of travel switch button, and travel switch is connected.
Compared with prior art, the utility model instrument has the following advantages:
Pressing plate of the present utility model covers on all travel switches, so can realize synchronous deciliter of all travel switches.Simultaneously the utility model is detachable assembling mode, can facilitate the replacing of travel switch, also can increase and decrease the quantity of travel switch, the utility model is simple and reliable for structure take up room little.
