Embodiment

Below in conjunction with drawings and Examples the utility model is elaborated.

Consult Fig. 2, Fig. 3, Fig. 4, the preferred embodiment that the utlity model has the mower of security protection effect comprises: a pedestal 2, a protective unit 3, a cutter 4, and a gripping unit 5.

This pedestal 2 comprises first section 21 of an oblique extension down, and second section 22 of being made progress by this top of first section 21 and stretching to retreading, and this first section 21 has an assembled portion 211 that is positioned at the bottom.

This protective unit 3 is to assemble with this assembled portion 211 removably, and comprise one around a central axis and 31, anti-guard housings 32 of ringwise assembling seat, and a block seat 33, described assembling seat 31, anti-guard housing 32 and block seat 33 define a bottom space 30 jointly.Described assembling seat 31 comprises a curved extension and is positioned at the leading section 311 of front side, and two ends and curved rearward end 312 that extends rear side that connects this leading section 311, the expanded range of this leading section 311 is that the front side by this assembling seat 31 extends to the left and right sides, accounts for about half of periphery of whole assembling seat 31.

Should prevent that guard housing 32 was connected the leading section 311 of this assembling seat 31, and comprise several equal angles settings and reaching each other forward towards the outstanding protection department 321 of and arranged on left and right sides, and all define jointly between the adjacent in twos protection department 321 opening outwardly and be communicated with this bottom space 30 wear groove 320.Described protection department 321 all comprises first shield segment 322 that is extended by leading section 311 radial outward of this assembling seat 31, and second shield segment 323 that is extended downwards by the front end of this first shield segment 322.

This block seat 33 is connected the rearward end 312 of this assembling seat 31, and comprises one from horizontally extending first retaining wall 331 of this rearward end 312 backwards, and second retaining wall 332 that is extended downwards by this first retaining wall 331.

This cutter 4 is belows of first section 21 that are assembled in this pedestal 2 removably, and is the bottom space 30 that is positioned at the below of this protective unit 3 after these cutter 4 assemblings, and described cutter 4 has a tool rest 41, and the cutter body 42 of this tool rest 41 of connection.

This gripping unit 5 comprises one by second section 22 of this pedestal 2 backward and the upward extension rod of stretching 51, an and gripping member 52 that is connected the top of this extension rod 51, this gripping member 52 comprises this extension rod 51 of a vicinity and is positioned at first holding part 521 of below, and second holding part 522 that is positioned at top.Because described cutter 4 and gripping unit 5 are not improvement emphasis of the present utility model, so no longer describe in detail.

When the utility model used, this cutter 4 can be subjected to one and be positioned at this mower inside and scheme unshowned motor driven, and then continues to rotate relative to this pedestal 2, and the cutter 4 in the rotation produces shear actions and can mow.User's hand is held this gripping unit 5 and is held this mower and continues to advance, this protective unit 3 and cutter 4 go deep in the weeds, when this mower is mobile forward, weeds can stretch into the described of this anti-guard housing 32 and wear in the groove 320, cutter 4 in the rotation just can touch the weeds that stretch into and it is cut off, this block seat 33 avoids the grass bits to fly to the user in order to block the grass bits that splash towards the rear.

Because first shield segment 322 of described protection department 321 extends a segment distance forward; and second shield segment 323 extends downwards; therefore cutter 4 can be positioned at the space of the below of described first shield segment 322 accordingly; and there is described second shield segment 323 to protect arround the cutter 4 again; so move in the use at mower; if there is for example barrier of wall in the place ahead; this mower is to remove this barrier of contact-impact with this anti-guard housing 32; this cutter 4 can directly not contact with barrier to some extent, therefore can reach the effect of protection cutter 4 by this anti-guard housing 32.And the design of anti-guard housing 32, when reaching safety protection function, the described groove 320 of wearing can make weeds stretch into and contacts cutter 4, can carry out cutting operation smoothly.

In addition, when the utility model was put in ground not using, this protective unit 3 flatly was positioned at ground and is coated on this cutter 4 outsides, made cutter 4 not exposed, avoided sharp-pointed cutter 4 to cause danger, reached the effect that safety is put.

In sum, reach the purpose of protection cutter 4, avoid cutter 4 in rotating use, collide the place ahead barrier and damage, therefore can prolong the service life of cutter 4, can reach the purpose of this utility model really by this anti-guard housing 32.And spirit of the present utility model is by this anti-guard housing 32 protection cutters 4, and the described groove 320 of wearing can stretch into weeds and contacts cutter 4, must not limit the kenel of this anti-guard housing 32 when implementing.
