    • A reversible monkey wrench includes a handle, a head, a slidable jaw, an axial rod and a worm gear. The handle has a connecting end for the head to abut thereagainst. The head is formed with a fixed jaw, a sliding rail, a receiving slot and a connecting bore. The connecting bore communicates with the receiving slot. A movable pin and a spring are disposed between the connecting end and the head. A top of the movable pin selectively inserts through the connecting bore. The spring urges the movable pin so that the movable pin may abut against the connecting end. The worm gear is adapted to control the slidable jaw to move and is slidably disposed in the receiving slot with respect to the axial rod. The movable pin selectively abuts against the worm gear to prohibit the worm gear from sliding.
    • 可逆的猴子扳手包括手柄,头部,可滑动的钳口,轴向杆和蜗轮。 手柄具有头部的连接端,以抵靠在其上。 头部形成有固定夹爪,滑轨,接收槽和连接孔。 连接孔与接收槽连通。 可动销和弹簧设置在连接端和头部之间。 可动销的顶部选择性地插入通过连接孔。 弹簧推动可动销,使得可动销可以抵靠连接端。 蜗轮适于控制可滑动的爪移动并相对于轴杆可滑动地设置在接收槽中。 可动销选择性地抵靠蜗轮以防止蜗轮滑动。

    • A reciprocatable open end wrench comprises a swing member allowing to slide relative to a concave arcuate surface of a second jaw, the radius of a convex arcuate surface of the swing member is equal to that of a concave arcuate surface of the second jaw, and between the concave arcuate surface and the convex arcuate surface is provided with an engagement structure having a slot member and a peripheral protrusion so as to engage with each other. Besides, the reciprocatable open end wrench further includes a stop portion for resisting against the torque of the swing member, thereby enhancing the strength and preventing the related components to be damaged.
    • 可往复运动的开口扳手包括允许相对于第二钳口的凹弧形表面滑动的摆动构件,摆动构件的凸形弓形表面的半径等于第二钳口的凹弧形表面的半径, 凹弧形表面和凸形弓形表面设置有具有槽构件和周边突起以使得彼此接合的接合结构。 此外,可往复运动的开口扳手还包括用于抵抗摆动构件的扭矩的止动部分,从而提高强度并防止相关部件被损坏。

    • A monkey wrench includes a handle, a head, stationary jaw, a movable jaw and a jaw-moving element. The head is formed at an end of the handle and made with a side, a groove in the side and an opening in communication with the groove. The stationary jaw is formed on the head and made with a first nut-contacting face, a second nut-contacting face next to the first nut-contacting face, a bulge on the first nut-contacting face and a recess next to the bulge. The movable jaw is movably disposed in the groove and formed with a nut-contacting face and a bulge on the nut-contacting face thereof. The jaw-moving element is disposed in the opening and engaged with the movable jaw so that the jaw-moving element is operable to move the movable jaw relative to the stationary jaw.
    • 猴子扳手包括手柄,头部,固定夹爪,可动夹爪和颚移动元件。 头部形成在手柄的端部,并且具有侧面,侧面的凹槽和与凹槽连通的开口。 固定夹头形成在头部上,并由第一螺母接触面,与第一螺母接触面相邻的第二螺母接触面,第一螺母接触面上的凸起和与凸起相邻的凹部形成。 可移动夹爪可移动地设置在凹槽中,并在其与螺母接触面上形成有螺母接触面和凸起。 钳口移动元件设置在开口中并与可动夹爪接合,使得爪移动元件可操作以相对于静止颚板移动可移动钳口。

    • A wrench includes a handle and an open-end with two jaws and each jaw has a driving surface. Each driving surface has a contacting area and two yielding areas. The contacting area is located between the two yielding areas and includes a contact portion and two notches. The contact portion is located between the two notches, and two extension areas each are connected between the yielding area and the notch corresponding thereto. A corner is formed at a joint area of the contact portion and an inside of the notch so as to bite a rounded fastener head. The contact portions are matched with straight sides of a normal fastener head.
    • 扳手包括手柄和具有两个钳口的开口端,每个钳口具有驱动表面。 每个驱动表面具有接触区域和两个屈服区域。 接触区域位于两个屈服区域之间,并且包括接触部分和两个凹口。 接触部分位于两个凹口之间,并且两个延伸区域各自连接在屈服区域和与其对应的凹口之间。 在接合部的接合部和切口的内侧形成有角部,从而咬合圆形紧固头。 接触部分与普通紧固件头部的直边匹配。
