In actual operation, the user holds the handle and applies downward force to maintain the blade at the desired height while applying a pushing force to promote the advancement of the grass machine for the purpose of grass. ...and for the above-mentioned lawn mower, the user must have skilled operation skills. In detail, (4) during the process, the manufacturer must constantly apply force to the handle and (4) balance it so that the blade can be relatively It is quite difficult and laborious to maintain at the required height. In a few cases, the conventional mower has the above-mentioned shortcomings and needs to be improved. In [New Content] The main purpose of this creation is to provide a blade high-level device for lawn mowers, which makes the lawn mower more simple and labor-saving in operation. In order to achieve the above purpose, the height of a lawn mower provided by the present invention is set to one of the lawn mowers: 1 = and -, the height of the production is adjusted. The frame is located between the handle and the blade 3 and has a receiving groove; and a ball is slidably disposed in the casing and the lower spherical surface is exposed in the casing Place the outside of the slot to resist the ground. The following is a description of the structure, features, and advantages of the present invention. The following is a description of the preferred embodiment of the present invention. The second drawing is a partial perspective cross-sectional view of the above preferred embodiment. The third picture is a cross-sectional view of the second figure. The fourth figure is a perspective view of the retaining frame of the above preferred embodiment. Referring to the first to fourth embodiments, a blade height adjusting device 100 according to a preferred embodiment of the present invention is mounted on a frame 21 of a lawn mower 200. The frame 210 is separated from front to back. A blade 22〇, a wheel set 23〇 and a handle 240 are provided; the blade height adjusting device 1〇〇 of the embodiment includes a housing 10, a ball 20, a blocking frame 30 and a plurality of balls 40; wherein: the housing 10, is movably coupled to the frame 210 through a plate 1〇1, and located between the blade 22〇 and the wheel set 23〇; wherein the housing 10 is in this embodiment a half ball housing having a downwardly open end 11 and a receiving groove 12, and an inlet pipe 13 communicating with the receiving groove 12 and a water inlet hole 14 formed at the end of the inlet pipe 13 The housing 10 is integrally formed with a retaining ring 15 around the water inlet hole 14 . The inlet pipe 13 is connected to an external water source (not shown) for guiding the water source to enter the retaining ring 15 according to the water inlet hole 14 . And accommodating the slot 12. The ball 20' is hollow. In this embodiment, the bracket is used. The ball 4G can be rolled (4) and the valley is described later. The upper spherical surface is surrounded by the receiving groove 12 and the ring. Two S1s are formed, and the lower spherical surface is exposed outside the accommodating slot 2 for resisting the ground G. First, the truss 30 includes a concentric-large diameter ring 31 and a J-ring 32 in this embodiment. a plurality of oblique ribs 33 connected between the large and small diameter rings 31, %; wherein the large diameter ring 31 is attached to the open end u of the casing 10 by a plurality of bolts (not shown) One end of the small diameter ring 32 constitutes a stop portion 34 ′ which is engaged by the stop 胄 34 and can be accommodated in the accommodating groove 12 of the casing ί, and the ball 20 is separated from the sling ring 15 A gap S2, and an adjacent opening rib 33 is formed with an opening %, the opening 35 is in communication with the receiving groove 12. The two balls 40' are hollow and are rollably accommodated in the space. In the case of $^, the sphere 20 can achieve the purpose of free rolling. The above is the description of the components of the blade height adjusting device 1 of the present embodiment. Referring to the first figure again, when the lawn mower 200 is actually operated, the operator can fix the blade height adjusting device _ to the appropriate position and fix it according to the height required by the blade 220. At this time, the blade height adjusting device _ The wheel set 230 collectively forms three support points, and the ball 2 〇 is in contact with the ground G and has a height. Therefore, the operator does not need to continuously apply force and balance to the handle 240, and the blade 220 can be maintained at a desired height. It is M381261. Compared with the apprentice, this creation is relatively simple and labor-saving in operation. Another point is that the device of this creation (9) will leave some weeds, mud and other impurities after use. In this regard, the user can connect the external water source to the inlet pipe 13 so that the water flows into the retaining ring 15 through the water inlet hole 14 and flows out through the gap S2, so that the water flow can smoothly and comprehensively follow the spherical flow of the ball 10. After that, the impurities are flushed out from the openings 35, thereby completing the cleaning operation. In summary, the constituent elements disclosed in the foregoing embodiments are merely illustrative and not used. Limiting the scope of the case, the substitution or variation of other equivalent components should also be covered by the scope of the patent application of this case. 6 M381261 [Simple description of the drawings] The first figure is a schematic diagram of the state of use of a preferred embodiment of the present invention. 2 is a perspective view of the above-described preferred embodiment.
