    • A saw blade tension adjusting apparatus of a band saw machine includes a retaining base, a movable base movably connected with the retaining base through two opposite sliding shafts, and a control unit having a handle and a cam connected with the handle so as to be driven to rotate between a tightening position and a loosening position. When the cam is located at the tightening position, the movable base is lifted by a large diameter portion of the cam to tighten the tension of a saw blade, and when the cam is located at the loosening position, the movable base is moved downwards to lean on a small diameter portion of the cam for loosening the tension of the saw blade.

    • A linear motion mechanism comprises a second rotating shaft having an external thread portion 48a at least at a part of an area in a length direction and an adjusting pin 40 having an opening 60 through which the external thread portion 48a passes. The opening 60 of the adjusting pin 40 has a cross-sectional shape that enables the adjusting pin 40 to move in a radial direction of the second rotating shaft. An inner thread part 62 that engages with and disengages from the external thread portion 48a of the second rotating shaft depending on a position of the adjusting pin 40 is formed on an inner surface of the opening 60. A spring 56 capable of retaining a state in which the external thread portion 48a and the inner thread part 62 engage with each other is arranged on the adjusting pin 40.
    • 直线运动机构包括第二旋转轴,其具有至少在长度方向上的区域的至少一部分上的外螺纹部分48a和具有外螺纹部分48a穿过的开口60的调节销40。 调节销40的开口60具有使调节销40能够沿第二旋转轴的径向移动的横截面形状。 根据调节销40的位置,与第二旋转轴的外螺纹部分48a接合并脱离的内螺纹部分62形成在开口60的内表面上。能够保持状态的弹簧56 外螺纹部48a和内螺纹部62彼此接合的位置设置在调节销40上。

    • A keyless adjusting mechanism for a chain saw is disclosed herein, which comprises a protection cover, an adjusting bolt, an adjusting stud, and an adjusting ring with a driver gear, wherein the adjusting bolt is coupled with a driven gear for engaging with the driver gear of the adjusting ring, the adjusting stud is coupled with a chain board and has a threaded hole for engaging with the corresponding adjusting bolt. Accordingly, when the adjusting ring is rotated, the driver gear can bring the driven gear to let the adjusting stud move axially along the adjusting bolt such that the chain could be adjusted to tighten or loosen. In addition, a knob with a handle is coupled to the adjusting ring. The handle can be withdrawn in the knob or extended out of the knob for convenient twist.
    • 本文公开了一种用于链锯的无钥匙调节机构,其包括保护盖,调节螺栓,调节螺柱和具有驱动齿轮的调节环,其中调节螺栓与从动齿轮联接,用于与驱动器接合 调节环的齿轮,调节螺柱与链板联接,并具有用于与相应的调节螺栓接合的螺纹孔。 因此,当调节环旋转时,驱动齿轮可以带动从动齿轮使调节螺栓沿着调节螺栓轴向移动,使得链可以被调节以收紧或松动。 此外,具有把手的旋钮连接到调节环。 手柄可以在旋钮中拉出或伸出旋钮,以方便扭转。
