摘要： A nail remover according to the present invention includes a tool head having a guide bore extending linearly through the head in a longitudinal direction, a push-rod slidably mounted in the guide bore of the head between a retracted position at which a free end of the push-rod is located in the guide bore and an extended position at which the free end of the push-rod protrudes from the guide bore, a driving device for advancing the push-rod from the retracted position to the extended position, and an actuator for activating the driving device. At least a portion of the peripheral wall defining an outlet of the guide bore is tapered toward an outboard edge of the wall so as to make it easy to introduce a nail into the guide bore. In operation, the guide bore receives the portion of a nail protruding from a plate such as a piece of plywood. Then the nail is straightened by aligning the guide bore with the axis of the nail and, thereafter, the push-rod is driven towards the extended position so as to drive the nail out of the plate.
摘要翻译：根据本发明的脱钉器包括具有沿纵向线性延伸穿过头部的导向孔的工具头，推杆可滑动地安装在头部的导向孔中，在该缩回位置处，推杆位于导向孔中，并且推动杆的自由端从引导孔突出的延伸位置，用于将推杆从缩回位置推进到延伸位置的驱动装置，以及致动器用于启动驱动装置。限定导向孔的出口的外围壁的至少一部分朝向壁的外侧边缘逐渐变细，以便容易地将钉引入导向孔。在操作中，导向孔容纳从板（例如胶合板）突出的指甲部分。然后通过将导向孔与钉子的轴线对齐来使钉子变直，然后将推杆朝向延伸位置驱动，以便将钉子从板上推出。

摘要： A tool primarily for pulling stakes from concrete forms includes a relatively long lever arm and a bore for encircling a metal stake, oriented generally at right angles to the lever arm. In preferred embodiments, the bore has a relatively sharp edge and gripping teeth for positive gripping engagement against the rod to enable twisting of the stake and subsequent lifting of the stake. The tool also includes, in preferred embodiments, a protruding fulcrum end to allow prying the stake up using the stationary wooden form for engagement by the fulcrum point. A further preferred feature is a chisel edge on the fulcrum end, to enable the tool to be used for form stripping. The chisel end may further include an opening configured for nail pulling. Thus, in a preferred embodiment the tool can be used for nail removal from forms, for stake twisting and pulling, for stripping of forms from concrete and also for bending of reinforcing bar to a substantially accurate, consistent bend angle. One preferred but optionally further feature is that the long lever is hollow through most of its length, enabling it to be used for straightening stakes that have been bent in the driving or removal process.
摘要翻译：主要用于从混凝土形式提取桩的工具包括相对长的杠杆臂和用于环绕通常与杠杆臂成直角定位的金属桩的孔。在优选实施例中，孔具有相对尖锐的边缘并且夹持齿以与杆成正面的夹持接合，以使得可以扭曲该桩并随后抬起该桩。在优选实施例中，该工具还包括突出的支点，以允许使用固定的木形来刺穿放样以用于由支点点接合。另一优选特征是在支点上的凿子边缘，以使该工具能够用于形式剥离。凿尖可以进一步包括构造成用于指甲拉动的开口。因此，在一个优选实施例中，该工具可以用于从形式中去除钉，用于桩的扭曲和拉拔，用于从混凝土中剥离形状，并且还用于将钢筋弯曲成基本准确的，一致的弯曲角。一个优选的但任选的另外的特征是长杠杆在其大部分长度上是中空的，使得其能够用于矫正在驾驶或移除过程中弯曲的桩。
