The directions of the upper, lower, left, right, front and rear are shown in fig. 4.

In the initial state, the first pressing plate 5 and the microswitch 3 are arranged in a staggered manner, namely the first pressing plate 5 is not positioned right above the microswitch 3, namely the first pressing plate 5 is positioned at the rear upper part of the microswitch 3, namely the first pressing plate is deviated to the direction of the button 4; when the button 4 is pressed, the first pressing plate 5 is driven by the button 4 to move forward to a position right above the microswitch 3.

The first pressing plate 5 is a deformable elastic member. More preferably, the first pressing plate 5 is provided with an elastic member at a position corresponding to the second pressing plate 7. The spring is preferably a spring leaf.

Be provided with on first clamp plate 5 and be used for the restriction dwang 6 further pivoted spacing arch 501, more specifically, fixedly connected with is spacing arch 501 on first clamp plate 5, and spacing arch 501's the position of setting is in one side that first clamp plate 5 is close to micro-gap switch 3.

Micro-gap switch 3 includes micro-gap switch casing 301, be provided with plate electrode 302 on micro-gap switch casing 301, more specifically, it has plate electrode 302 to articulate on micro-gap switch casing 301, be equipped with on micro-gap switch casing 301 and decide touch multitouch 303, the one end of plate electrode 302 and decide touch multitouch 303 cooperation make micro-gap switch 3 open.

In order to ensure that the micro switch 3 is turned on, the first pressing plate 5 always presses the electrode plate 302 in the micro switch 3, and the operator holds the rotating rod 6 and the grab bar 1 at the same time. (because dwang 6 and handrail 1 position are comparatively close, operating personnel can hold simultaneously), the micro-gap switch 3 opens and makes the circular telegram in-process of power promptly, and operating personnel need keep holding dwang 6 and handrail 1 simultaneously all the time. First clamp plate 5 makes electrode board 302 and fixed contact 303 keep the contact state, so set up spacing arch 501 to can restrict button 4 and first clamp plate 5 and can not move backward, make under the effect of second clamp plate 7, first clamp plate 5 is in the top of micro-gap switch 3's electrode board 302 all the time, and the extrusion between second clamp plate 7 and the first clamp plate 5 can let micro-gap switch 3 keep the on-state just.

Be equipped with the first spring 8 that is used for reset button 4 between button 4 and the switch housing 2, the cover is equipped with the second torsional spring 9 that is used for resetting dwang 6 on dwang 6. The arrangement of the first spring 8 and the second torsion spring 9 can conveniently realize the reset of the button 4 and the rotating rod 6.

The handrail 1 comprises a horizontal rod and two parallel inclined rods connected to two sides of the horizontal rod, the two ends of the rotating rod 6 are arranged in the switch shell 2, and the two inclined rods are arranged in the handrail 1 in a pivoting mode and are arranged oppositely. The dwang 6 includes the horizontal portion of gripping and the pivot portion that sets up in the portion of gripping both ends that is connected with the portion of gripping, the pivot portion is "L" type design, switch housing 2 is stretched out to the horizontal portion of gripping in the dwang 6, and the horizontal portion of gripping in the dwang 6 supplies operating personnel to grip.

Dwang 6 is equipped with and rotates cover 10 near a pot head of button 4, second briquetting 7 fixed connection be in rotate the cover 10 on. The rotating sleeve 10 is designed to be inverted T-shaped, one end of the rotating sleeve 10 is sleeved on the pivoting part of the rotating rod 6 and can rotate along with the rotation of the rotating rod 6, and the other end of the rotating sleeve 10 is erected in an arc-shaped groove of an arc-shaped plate 12 arranged on the inner side of the switch shell 2. An arc-shaped plate 12 for mounting the rotating sleeve 10 is arranged in the switch shell 2, and an arc-shaped groove is formed in the arc-shaped plate 12.

Be equipped with limit structure 11 in the switch housing 2, limit structure 11 restriction button 4 excessively removes towards the switch housing 2 outside. The limit structure 11 is a flange provided on the outer periphery of the push button, the flange extending outward in the circumferential direction of the push button, and the size of the flange is larger than the through hole of the push button 4 moving forward and backward on the switch housing 2, so that the push button can be prevented from moving excessively toward the outside of the switch housing 2.

When the mower is operated, an operator holds the grab bar 1 and the rotating rod 6 at the same time to keep the mower in the power-on operation state.

The method comprises the following specific steps: when the mower needs to be started, the button 4 is pressed first, the button 4 moves towards the arrangement direction of the first spring 8, the button 4 moves, meanwhile, the first pressing plate 5 is driven to move above the microswitch 3, and at the moment, the first pressing plate 5 is not in contact with the microswitch 3. When pressing button 4, operating personnel rotates dwang 6, and dwang 6 rotates and drives second briquetting 7 and rotate, and first clamp plate 5 is extruded downwards to second briquetting 7, because limit structure 11's limiting displacement, first clamp plate 5 does not move downwards, nevertheless because first clamp plate 5 is the elastic component that can deform, and first clamp plate 5 produces deformation. And the limit bulge 501 on the first pressing plate 5 is matched with the second pressing plate 7, so that the button 4 and the first pressing plate 5 cannot move backwards, thus the second pressing plate 7 keeps a state of pressing the first pressing plate 5, the first pressing plate 5 presses the electrode plate 302 in the microswitch 3, one end of the electrode plate 302 is in contact with the fixed contact block 303 to be electrified, and the microswitch 3 is started.

At the moment, the rotating rod 6 rotates to the position attached to the grab rail, and an operator can hold the rotating rod 6 and the grab rail at the same time to ensure that the microswitch 3 is in an open state and the mower works normally.

After using the mower, the operator only needs to release the hand from the rotating rod 6, the rotating rod 6 can be reset under the action of the second torsion spring 9, and the button 4 can be reset under the action of the first spring 8.
