Between individual connection ring, and sawtooth outer end tip is radially less than connection ring external diameter with cut ring interior edge distance along cut ring and cutterhead is straight
The difference in footpath, annular shell-like guard ring is additionally provided with connection ring, guard ring is connected to connection ring outer, and is respectively provided at two companies
Connect the opposite side of ring.
The rotating device of mounting hole and hay mover is connected, is rotated with band movable knife disc, under normal circumstances, is cut using sawtooth
Grass, once sawtooth encounters hard thing, because fastener two is made up of easily broken material, therefore fastener two can be made in cut ring and connection
Cut off between ring, afterwards cut ring and connection ring separation, due to sawtooth outer end tip along cut ring radially with cut ring interior edge away from
From the difference less than connection ring external diameter and cutter diameter, therefore with the cut ring that hard thing contacts two connections are hidden in together with sawtooth
Between ring and cutterhead, now guard ring contacts with hard thing, avoids cutterhead from fractureing, therefore this blade security is higher, afterwards can be with
Fastener two is retightened to be continuing with.
In a kind of above-mentioned safe mower blade with safeguard structure, in described two connection rings and cutterhead respectively
The connecting hole being communicated with, fastener one and connecting hole coordinate, and two connection rings is separately fixed at cutterhead both sides, cut ring and
The fixing hole of connection is respectively equipped with two connection rings, fastener two coordinates with fixing hole, makes cut ring and two connection ring phases
It is fixed.
Therefore it is easy for installation.
In a kind of above-mentioned safe mower blade with safeguard structure, described fastener one is hard metal system
Into fastener two is made up of wooden or plastics.
Fastener two can also use other easily broken materials.
In a kind of above-mentioned safe mower blade with safeguard structure, described cut ring interior edge and cutterhead outer point
Not Tu Fuyou oily wax, described guard ring is structure as a whole with connection ring.
Oily wax plays lubrication.
Compared with prior art, the utility model has the following advantages that：
The rotating device of mounting hole and hay mover is connected, is rotated with band movable knife disc, under normal circumstances, is cut using sawtooth
Grass, once sawtooth encounters hard thing, because fastener two is made up of easily broken material, therefore fastener two can be made in cut ring and connection
Cut off between ring, afterwards cut ring and connection ring separation, due to sawtooth outer end tip along cut ring radially with cut ring interior edge away from
From the difference less than connection ring external diameter and cutter diameter, therefore with the cut ring that hard thing contacts two connections are hidden in together with sawtooth
Between ring and cutterhead, now guard ring contacts with hard thing, avoids cutterhead from fractureing, therefore this blade security is higher, afterwards can be with
Fastener two is retightened to be continuing with.

Embodiment
It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As Figure 1-3, a kind of safe mower blade with safeguard structure of the utility model, including home position are provided with
The disc cutterhead 1 of mounting hole, in addition to annular cut ring 3 and two annular connection rings 2, if the outer of cut ring 3 is provided with
Dry sawtooth 31, some sawtooth 31 are circumferentially distributed along cut ring 3, the external diameter of cut ring 3, the external diameter of connection ring 2, the internal diameter of cut ring 3, cutterhead
1 diameter and the internal diameter of connection ring 2 are sequentially reduced, and cut ring 3 is identical with the thickness of cutterhead 1, and two connection rings 2 pass through one 11 points of fastener
The both sides of cutterhead 1 it are not fixed on coaxially, cut ring 3 is coaxially fixed on two connection rings by fastener 2 32 made of easily broken material
Between 2, and the outer end tip of sawtooth 31 is less than the external diameter of connection ring 2 with the interior edge of cut ring 3 distance along the radial direction of cut ring 3 and cutterhead 1 is straight
The difference in footpath, annular shell-like guard ring 21 is additionally provided with connection ring 2, guard ring 21 is connected to the outer of connection ring 2, and is respectively provided at
