New description: [New technical field] The present invention relates to a handle angle adjusting device, in particular to a handle angle adjusting device of a lawn mower. [Prior Art] As shown in Fig. 1, the handle 11 of the general lawn mower 1 (such as a J-type single rod, a U-shaped double rod...) is inclined, and can be used by the user to push and apply force to cut Grass work. However, the design of the tilt angle or the grip height of the handle 11 is usually fixed, and cannot be adjusted or changed depending on the object of use during use, and cannot be folded when not in use, so that the lawn mower as a whole It is less convenient to use and takes up a lot of space. [New content] Therefore, the object of the present invention is to provide a handle angle adjusting device for a lawn mower that can improve the ease of use of the lawn mower and reduce its occupation space. Therefore, the handle angle adjusting device of the novel lawn mower includes a working table, and a handle disposed on the rear end surface of the working table, the handle angle adjusting device includes at least one adjusting unit disposed at the Actuating the rear end face of the table and connecting one end of the handle. The adjusting unit comprises a connecting seat fixed to the rear end surface of the working platform, a lever pivotably disposed on one side of the child connecting seat, and an arc pivoted on the opposite side of the connecting seat And a pivoting member on the side of the connecting seat pivoted at the position of the guiding strip. The lever can be driven by the lever and the 5 M332366 is swung back and forth between the first position and the second position relative to the connecting seat. The pivoting member has a swinging portion connecting the end portion of the handle, and a stopping portion that is driven from the swinging portion; when the guiding toothed strip is in the first position, the stopping portion is in a relative position Changingly engaging the guide rack to enable the swinging portion to swing up and down and positioning; when the guide rack is in the second position, the stop portion is separated from the guide rack, and the swing portion is It is possible to tilt forward in the direction of the motive station.
本新4«之功效在於，利用該樞擺件能相對位置可變地 與該導齒條相喃合，以上下擺動至定點並帶動該把手產生 傾斜角度與握持高度變化；配合該撥桿能驅使該導齒條脫 離該樞擺件，使該樞擺件能朝前翻傾、定位並帶動該把手 收合，藉以使該割草機之使用便利性佳且佔用空間小。 【實施方式】 有關本新型之前述及其他技術内容、特點與功效，在 、下配a參考圖式之一個較佳實施例的詳細說明中，將可 清楚的呈現。 如圖2與圖3所示，本新型割草機的把手角度調整裝 置的該較佳實施例，該割草冑3包含—作動機台Μ，以及 一設置於該作動機台31後端面的把手32。本實施例中，該 把手32是U型雙桿式者。 孩割皁機的把手角度調整裝 —^ 〜u 6 一苁別設置於該 <〇 31後端面之相反兩側部，且分別連接該把手w 之二底端部321的調整單元2。該二調整單元2是能相互連 動以同步作動，每一調整單元2包括一固定於該作動機台 6The function of the new 4« is that the pivoting member can be variably and symmetrical with the guide rack, and swings to a fixed point and drives the handle to generate a tilt angle and a grip height change; The guide rack is driven away from the pivoting member, so that the pivoting member can tilt forward, position and drive the handle to be folded, so that the lawn mower can be conveniently used and occupy a small space. [Embodiment] The foregoing and other technical contents, features, and advantages of the present invention will be apparent from the detailed description of a preferred embodiment of the accompanying drawings. As shown in FIG. 2 and FIG. 3, in the preferred embodiment of the handle angle adjusting device of the novel lawn mower, the mowing mower 3 comprises an actuating table, and a rear end surface of the moped table 31. Handle 32. In this embodiment, the handle 32 is a U-shaped double rod type. The handle angle adjustment device of the child's soap-cutting machine is provided on the opposite side portions of the rear end surface of the <〇 31, and the adjustment unit 2 of the bottom end portion 321 of the handle w is respectively connected. The two adjusting units 2 are connected to each other for synchronous operation, and each adjusting unit 2 includes a fixing unit 6

The bottom end portion 321 and the pivoting member 25 of the guide rack 23, and a connecting rod 26 for sequentially connecting the lever 22, the elastic member 24, the connecting seat 21 and the guide rack 23 in series . In this embodiment, the pivoting member 25 and the handle 32 are separately formed and then assembled. Of course, the two can also be a homogenous molded structure; and the elastic member 24 is a torsion spring. The connecting rod 26 is rotatably inserted through the connecting seat 21, and the connecting rod 22 and the guiding rack 23 are fixed to the connecting rod 26, and the elastic member 24 is pivoted on the connecting rod 26. And the two ends of the connecting rod 22 and the connecting seat 21 are respectively fixed at the two ends; thereby, the connecting rod 22 can drive the guiding rack 23 to swing back and forth between the first position and the second position with respect to the connecting seat 21 The elastic member 24 is used to drive the lever 22 to automatically move the guide rack 23 from the second position to the first position. Therefore, in the case of the two adjusting units 2, the two connecting rods 26 are integrally connected. When the lever 22 of one of the adjusting units 2 drives the guiding rack 23 to swing, the other adjusting unit 2 can be synchronously driven. The lever 22 and the guide bar 23 actuate. Furthermore, the connecting seat 21 of each adjusting unit 2 has an arc slot 211 7 M332366. The pivoting member 25 has a 兮 兮 / , , , , , , , , , , , , , , , , , , , , , , , , , , , The swinging portion 251 and the one-to-one swinging direction of the bean 251 are opposite to the swinging portion edge "" portion 252, and a recess is provided in the side of the stopper portion 252. The guide bar 23 is substantially L-shaped, and has a retaining ring 252 0 > 252 which can completely disengage the pivoting member 25 and can swing the arc after the lever 22 is connected a rack body 231, a bump that is perpendicular to the top π of the rack body 231 and that can be driven to swing up and down, and a side perpendicular to the block 232 facing the connecting seat 21 and capable of a limiting post 233 that slides up and down in the arc slot 211; and the limiting post is coupled with the arc slot 211 to cause the blocking lug 232 to swing up and down within a certain angle, and the tooth The strip body 231 is oscillated back and forth within a certain angle. As shown in FIG. 4, when the lever 22 is not toggled and the guide rack 23 is in the first position, the limit post 233 of the guide rack 23 is engaged in the upper end of the arc slot 211. To utilize the blocking protrusion 232, the stop portion 252 of the pivoting member 25 is designed to be blocked (ie, the blocking projection 232 represents the highest position of the stopping portion 252, and the swinging portion 251 and the handle are opposite to the handle The lowering point of 32 is such that the swinging portion 251 and the stopping portion 252 are vertically oscillated opposite to each other in a certain angle, and the inclination angle of the handle 32 is changed as the swinging portion 251 swings upward. The height of the grip is increased, and as the swinging portion 251 swings downward, the tilt angle of the handle 32 is reduced and the grip height is lowered, and the retaining portion 252 can be engaged with the purlin body 231 of the guide rack 23. Engaging so that the swinging portion 251 can be stably held after the stop, the handle 32 can be maintained at a predetermined tilt angle and grip height. As shown in FIG. 5, when the lever 22 is pushed downward to drive the sway of the guide 8 M332366 23 to the initial position of the second position, the #1 body 23i will swing forward and directly and quickly disengage. The stopping portion 252 of the pivoting member 25, while the _bump 232 swings downward to get into the groove 253, and the limiting post 233 is slid to be stuck in the lower end of the arc groove 211; then, The pure hand η can drive the swinging portion 251 to tilt forward toward the driving table 31 while causing the stopping portion 252 to swing backward. As shown in FIG. 6, when the handle 32 is tilted forward to fold up against the actuator table 31, and the lever 22 is placed, the elastic member 24 can drive the lever 22 to drive the guide. ^ Bar 23 is automatically reset back to the first position. κ: When using the pivoting member 25, the pivoting member 25 can swing up and down to relatively align with the guiding rack 23, so that the handle 32 can be directly pulled according to the object to be used. The pivoting member 25 is oscillated up and down, and then stabilized after the stop, #to achieve the purpose of simple and safe adjustment of the continuation: the inclination angle of the second and the height of the grip, effectively improving the lawn mower
