摘要： A saber saw includes a housing, a plunger supported within the housing and being free to reciprocate, and a swingable guide sleeve provided within the housing and connected with the plunger for imparting a swinging motion to the plunger. In the saber saw, a plunger holding device includes a cylindrical resilient member provided between the guide sleeve and the housing. The resilient member is in fluid-tight contact with the housing.

摘要： An apparatus having a foot, a reciprocating saw and a housing. Between the foot and the housing there are means for releasable mounting the foot on the housing, characterized in that the releasable mounting means have a first coupling member connected to the foot and, co-acting therewith, a second coupling member connected to the housing. The coupling members can be carried from a disconnected to a connected position by a relative displacement between the foot and housing.

摘要： A light duty electric reciprocating handsaw includes a body assembly having a throat therein, a removably and reciprocally attached saw blade within the body assembly spanning the opening of the throat so that any workpiece that fits inside the throat can be cut across its width. The handsaw is either electrically or battery operated and includes an electric motor mounted within the body assembly, the weight of the motor being generally distributed over the saw blade. Preferably, the throat of the body assembly is generally defined by an upside down U-shaped configuration for receiving the workpiece therein after cutting with the saw blade. A balance of the weight is located generally over the saw blade, with the remainder of the weight of the unit being distributed generally evenly throughout the rest of the handsaw such that the operator will experience an aid in cutting the workpiece through the force of gravity. A a reciprocating handsaw holder in accordance with the invention includes a bracket for receiving the reciprocating handsaw which is pivotally and slidably mounted to a base which further includes a workpiece assembly support to hold the workpiece in place while the reciprocating handsaw is in operation.
摘要翻译：轻型电动往复式手锯包括其中具有喉部的主体组件，在主体组件内跨过喉部开口的可移除和往复连接的锯片，使得适合于喉部内部的任何工件可以横切其宽度。手锯是电气或电池操作的，并且包括安装在主体组件内的电动马达，电动机的重量通常分布在锯片上。优选地，主体组件的喉部通常由倒置的U形构造限定，用于在用锯片切割之后接收工件。重量的平衡通常位于锯片上，其中单元的重量的其余部分大致均匀地分布在手柄的其余部分中，使得操作者将经历借助于重力来切割工件的辅助。根据本发明的往复式手持式保持器包括用于接收往复式手锯的支架，其可枢转地和可滑动地安装到基座，该基座还包括工件组件支撑件，以在往复式手锯工作时将工件保持在适当位置。

摘要： A reciprocating saw includes a structure for sealing a chamber (2a) which is defined by a gear housing (3) and a gear housing cover (4) fitted over the gear housing. The sealing structure includes a rubber packing (18) mounted along the entire length of the seam between the gear housing (3) and the gear housing cover (4). The rubber packing (18) is integrally formed with a V-shaped valve (19) such that a protrusion (20) at the bottom bend of the valve selectively opens and closes an air vent (21) formed in a partition wall (3a) of the gear housing (3). The sealing structure further includes a seal retainer (22) and a dust seal (24) provided between the gear housing (3) and the gear housing cover (4) and penetrated by a reciprocating slider (12). The seal retainer (22) and the dust seal (24) lubricate the slider and seal the chamber (2a) where the slider 12 penetrates the chamber.
摘要翻译：往复锯包括用于密封由齿轮壳体（3）限定的腔室（2a）和安装在齿轮壳体上的齿轮壳体盖（4）的结构。密封结构包括沿着缝隙的整个长度安装在齿轮壳体（3）和齿轮壳体盖（4）之间的橡胶密封件（18）。橡胶密封件（18）与V型阀（19）一体地形成，使得阀的底部弯曲处的突起（20）选择性地打开和关闭形成在隔壁（3a）中的通风口（21）的齿轮箱（3）。密封结构还包括密封保持器（22）和设置在齿轮壳体（3）和齿轮壳体盖（4）之间并由往复滑动件（12）穿过的防尘密封件（24）。密封保持器（22）和防尘密封件（24）润滑滑块并密封滑块12穿透室的腔室（2a）。
