    • PROBLEM TO BE SOLVED: To provide a gardening trimmer which is designed such that flexible elastic bushings are not damaged by load applied to a crank cam when a reduction gear and the crank cam are connected with connection pins via the flexible elastic bushings.SOLUTION: A hedge trimmer 10 is equipped with: a reduction gear 31 which rotates by an operation of an electric motor 21; a crank cam 34 which is connected to the reduction gear 31 with connection pins 35,35 and rotates with the reduction gear 31; a pair of shear blades 41,42 which are engaged with the crank cam 34 to relatively reciprocate. In the hedge trimmer 10, one ends of the connection pins 35,35 are fixed to the crank cam 34 in a fitted manner, the other ends of the connection pins 35,35 are elastically fitted to connection holes 32,32 formed in the reduction gear 31 via flexible elastic bushings 36,36, and stoppers 37,37 which restrict deformation of the flexible elastic bushings 36,36 caused by load applied to the crank cam 34 are provided.
    • 要解决的问题:提供一种园艺修剪机,其设计成使得当减速齿轮和曲柄凸轮通过柔性弹性衬套与连接销连接时,柔性弹性衬套不会受到施加到曲柄凸轮上的负载的损坏。解决方案:A 树篱修剪器10配备有:通过电动机21的操作而旋转的减速齿轮31; 曲柄凸轮34,其与连接销35,35连接到减速齿轮31并与减速齿轮31一起旋转; 一对剪切刀片41,42,其与曲柄凸轮34接合以相对往复运动。 在树篱修剪器10中,连接销35,35的一端以嵌合的方式固定在曲柄凸轮34上,连接销35,35的另一端弹性地嵌合在形成在还原装置中的连接孔32,32上 提供通过柔性弹性衬套36,36的齿轮31和限制由施加到曲柄凸轮34的负载引起的柔性弹性衬套36,36的变形的止动件37,37。
