Cutter, can also be rope of beating the grass.
When the garden instrument starts, the driving pulley 21 drives 33 turns of the big belt wheel by the way that belt is (not shown)
It is dynamic so that elastic deformation occurs for the elastic element 34, so that the driving wheel 32 is under the action of the elastic element
Rotation.At this point, state as shown in Figure 14 is gradually converted into state shown in Figure 12 by the elastic element 34, i.e.,：The bullet
Property element 34 by elastic deformation minimum condition conversion be the maximum state of elastic deformation.When the garden instrument is with stable state
When operation, the elastic element 34, the second protrusion 336 push the driving wheel 32 to rotate jointly.At this point, the master arm 422,
Slave arm 423 is disengaged with the friction plate 41 under the influence of centrifugal force.
It please refers to Fig.1 shown in 3, when the garden instrument is shut down, since the big belt wheel 33 is connected to the motor, under rotating speed
Drop is fast, and the driving wheel 32 is connected with Working mechanism, such as cutting blade, and inertia is larger, and rotating speed decline is slower, in addition,
Under the action of the elastic element 34, relatively rotate between the driving wheel 32 and the big belt wheel 33 so that described
Holding block 321 is held in the master arm 422, and due to leverage, the brake block 42 is rotated around the articulated section 421, institute
It states slave arm 423 and is held in the friction plate 41.Due to the rubbing action between the friction wall 424 and the friction plate 41,
So that the rotating speed of the driving wheel 32 declines rapidly, until the driving wheel 32 stops operating, and then reach so that operation
The purpose that mechanism stops rotating in a short time.Again institute is may make since the holding block 321 is held in the master arm 422
It states braking mechanism 40 to work, the brake block 42 is preceding without overcoming any frictional force, therefore the braking mechanism in action
40 response speed is very fast.
It should be pointed out that in other embodiments, the elastic element 34 can remove, and have no effect on the braking machine
The realization of the basic brake function of structure 40.At this point, when the garden instrument starts, the driving pulley 21 drives the big band
33 rotation of wheel, second limited block 336 support second protrusion 325, the driving wheel 32 are pushed to rotate.When the gardens
When tool stops, since the big belt wheel 33 is connected to the motor, rotating speed declines soon, and the driving wheel 32 and Working mechanism, example
Such as cutting blade, it is connected, inertia is larger, and rotating speed decline is slower, and phase occurs between the driving wheel 32 and the big belt wheel 33
To rotation so that the holding block 321 is held in the master arm 422, and due to leverage, the brake block 42 is around the pivot
Socket part 421 rotates, and the slave arm 423 is held in the friction plate 41.Due to the friction wall 424 and the friction plate 41 it
Between rubbing action so that the rotating speed of the driving wheel 32 declines rapidly, until the driving wheel 32 stops operating, in turn
Achieve the purpose that so that Working mechanism stops rotating in a short time.
In conclusion the garden instrument of the utility model is held in the master arm 422 by the holding block 321
So that the braking mechanism 40 works, so that the brake response speed of the utility model garden instrument is very fast, brake effect
Fruit is preferable, improves the security performance of the garden instrument.
In particular, for those of ordinary skill in the art, made by under the introduction of the utility model
