Reference numeral

Blade 40 is rolled in disc substrate 10, sawtooth portion 20, the first spine 21, the second spine 22, storage tank 23, blade tip portion 30, Hollow hole 50, internal channel 60, predetermined angle theta, cutting blade direction S.

Specific embodiment

Presently filed embodiment is described in detail below in conjunction with accompanying drawings and embodiments, thereby how the application is applied Technological means can fully understand and implement according to this to solve technical problem and reach the realization process of technical effect.

It please refers to Fig.1, Fig. 1 is the mowing piece stereogram of the embodiment of the present application.As shown in the figure, a kind of mowing piece includes disk Matrix 10；It is arranged at intervals at multiple sawtooth portions 20 around disc substrate 10；It is welded in the blade tip portion 30 in sawtooth portion 20；It is set to Multiple folding blades 40 of disc substrate 10,0 opposed discs matrix of multiple folding blades, 10 center circumferential array, have and blade tip portion 30 Identical cutting blade direction S；And it is set to the hollow hole 50 of disc substrate 10.In one embodiment of the utility model, disk Matrix 10 is set on grass trimmer, and the sharp sawtooth portion 20 of surrounding and blade tip portion 30 cooperate, and realizes cutting weeds, and is located at Multiple folding blades 40 of circumference array on disc substrate 10 have the larger knife edge and blade, can give on rough meadow The sundries such as upper cutting branch, shrub improve use scope, meadow are facilitated to cut.In addition, the hollow hole 50 of disc substrate 10 reduces Quality obtains larger cutting speed while reducing cost, convenient and practical.

Please continue to refer to Fig. 2, Fig. 2 is 20 partial enlarged view of sawtooth portion of the embodiment of the present application.Sawtooth portion 20 includes first 21 and second spine 22 of spine, forms storage tank 23 between the first spine 21 and the second spine 22, storage tank 23 is bonded blade tip portion 30；Wherein the first spine 21 is less than the second spine 22.In one embodiment of the utility model, relatively low first spine 21 with compared with The second high spine 22 has been connected to form sawtooth, realizes the circumgyration incision of mowing piece.There is accommodating blade tip portion 30 among the two Storage tank facilitates it to be welded and fixed, and three is connected to form the sawtooth of a similar saw blade, easy to use.

Next, please continue to refer to Fig. 3, Fig. 3 is multiple 20 connection diagrams of sawtooth portion of the embodiment of the present application.Blade tip portion 30 head is smoothly connected with the second spine 22 outer rim, and blade tip portion 30 is with respect to the side partial denudation of the first spine 21.In this reality It applying in mode, cutting blade direction S is intended to the first spine 21, therefore blade tip portion 30 has the exposed side outside the first spine 21, Facilitate realization circumgyration incision, in order to avoid the first relatively low spine 21 that crumbles.And the side that blade tip portion 30 is connected with the second spine 22 is real It is now connected smoothly, fully contradicts blade tip portion, form support, improve the stability of cutting, strengthen cutting efficiency and improve to make Use the service life.

In addition, the song of indent is set as by 50 round and smooth connection of internal channel, 50 surface of internal channel between multiple sawtooth portions 20 Line is used and facilitates chip removal, improves the effective length of cutting, makes weeds filling in internal channel 50, increasing more weeds cutting.

Please also refer to Fig. 1 and Fig. 4, Fig. 4 is the mowing piece side view of the embodiment of the present application.Folding blade 40 is set as by justifying Disc board 10 turns down the right angle arcs of predetermined angle theta, and right angle arcs have the cutting edge along cutting blade direction S.Blade 40 is rolled over by disk Substrate 10 turns down, and facilitates punch process, is integrally formed, and improves the rigidity of structure, enhances the stability of cutting.It is worth mentioning It is that predetermined angle theta is set as 15 ° ~ 30 °, when predetermined angle theta is set as smaller 15 ° by the utility model, can cut relatively low Weeds, shrub and stone, conveniently manually adjust, have fine tuning effect；In addition can also weeds be prevented to be wound on electric machine main shaft, Realize cut-out.And when predetermined angle theta is set as larger 30 °, facilitate the meadow for cutting higher weeds, be fully rotatable cutting, It is convenient and practical.In addition in one embodiment, predetermined angle theta is set as 20 °, meets more multi-environment use, grass trimmer tilts It is easy to adjust, while cutting meadow practicality, it can also facilitate cutting sundries.

Several preferred embodiments of the application have shown and described in above description, but as previously described, it should be understood that the application Be not limited to form disclosed herein, be not to be taken as the exclusion to other embodiment, and available for various other combinations, Modification and environment, and the above teachings or related fields of technology or knowledge can be passed through in application contemplated scope described herein It is modified.And changes and modifications made by those skilled in the art do not depart from spirit and scope, then it all should be in this Shen It please be in the protection domain of appended claims.
