摘要： Drive shaft of a plant cutter apparatus includes an elongate main shaft portion made of a titanium alloy, and end shaft portions made of steel and integrally joined to the opposite ends of the main shaft portion. The titanium alloy has substantially the same mechanical strengths as the steel. Therefore, the titanium-alloy-made main shaft portion can secure rigidity that is normally required of the plant cutter's drive shaft, and can also reduce the weight of the drive shaft to thereby minimize unwanted sagging-induced vibrations of the drive shaft caused by the shaft's own weight.
摘要翻译：植物切割装置的驱动轴包括由钛合金制成的细长主轴部分和由钢制成的端轴部分并且与主轴部分的相对端一体地接合。钛合金具有与钢大致相同的机械强度。因此，钛合金制的主轴部分可以确保工厂切割器的驱动轴通常所需的刚性，并且还可以减小驱动轴的重量，从而最小化不必要的下垂引起的驱动轴的振动轴自身重量。

摘要： An operational lever for a bush cutter includes a handle housed in a handle case, a throttle lever pivotally mounted to the handle, and a lock lever pivotally mounted to the handle. The operational lever further includes a torsional coil spring which exerts a resilient force on the lock lever. The lock lever is pivoted from an initial position to a pivoted position by an operator's palm. The throttle lever is then pivoted to a half-pivoted position by operator's fingers. When the palm is moved a small distance away from the handle case with the throttle lever held in the half-pivoted position, the lock lever is pivoted back towards the initial position by a resilient force of the spring. This causes a curved surface of a side protrusion portion of the lock lever to engage or abut on a side of a protrusion portion of the throttle lever. This arrangement is advantageous in that even when the operator takes her or his fingers off the throttle lever, the throttle lever is locked by a friction force produced between the curved surface and the side.
摘要翻译：用于衬套切割器的操作杆包括容纳在手柄壳体中的手柄，可枢转地安装到手柄的节气门杆和可枢转地安装到手柄的锁定杆。操作杆还包括在锁定杆上施加弹性力的扭转螺旋弹簧。锁定杆由操作者的手掌从初始位置枢转到枢转位置。然后操作者的手指将节流杆枢转到半枢转位置。当手掌离开手柄壳体一小段距离，油门杆保持在半枢转位置时，锁定杆通过弹簧的弹力向初始位置枢转回来。这导致锁定杆的侧突出部分的弯曲表面接合或邻接在节流杆的突出部分的一侧。这种安排的优点在于，即使当操作者将她或他的手指从油门杆上取下时，油门杆被弯曲表面和侧面之间产生的摩擦力锁定。

摘要： A bush cutting machine including an automatic braking mechanism having a brake drum formed integrally with a clutch case which houses a centrifugal clutch. When the number of rotations of a clutch drum decreases, at least two braking members press against the brake drum, whereby the clutch drum stops rotating, and a cutting blade also stops rotating automatically.

摘要： A vegetation trimming and edging device has an adjustable head that permits selective positioning between trimming and edging orientations. A shaft extends between the head and a handle. The head receives one end of the shaft. A coupling mechanism couples the head and shaft, and locks the head against rotational movement about the shaft. In particular, the coupling mechanism includes a locking structure and a bias mechanism. The bias mechanism urges the locking structure into engagement to prevent rotational movement of the head. Downward pressure applied to the head overcomes the bias, however, and disengages the locking mechanism for rotation of the head between trimming and edging modes. When the downward pressure is released, the locking mechanism is again engaged to lock the head in position for the desired operational mode.

摘要： A brake device disposed in the vicinity of a clutch drum has a leaf spring having a brake pad thereon which is brought into slidable contact with the clutch drum. A cam member and a compression coil spring which opposes a cam member with the leaf spring disposed therebetween are provided on a free end of the leaf spring. The cam member is rotated by a rotatable shaft together with a pinion gear which meshes with a rack formed on a stand. When a trimmer is placed on the ground, the stand is moved upwardly and the brake pad is brought into the braking position where the brake pad slidably contacts with the clutch drum. This braking position is released when an operation lever is operated by an operator.

摘要： A portable power machine comprises a longitudinally extending rod having an output control and a brake control. From the brake control, a brake action member and a brake gang member control are extended in the opposite directions from each other. A brake gang member and an output gang member have abutting portions to restrict output to the working member by the output control when the working member is in the braked state and to restrict the brake control of the working member when the working member is driven by the output of the motor.
