    摘要: An orthopedic impacting tool comprises a motor, a linear motion converter, an air chamber, a compression piston, an impacting element, an anvil element, and a broach adapter. The compression piston may cause the impacting element to apply controlled force on a broach adapter to create a precise opening for subsequently disposing a prosthesis in a patient. The tool may further comprise a detent for holding the impacting element in a position until a sufficient pressure is applied to release the impacting element. The tool allows forward or backward impacting for expanding the size or volume of the opening or for facilitating removal of the broach and tool from the opening. A force adjustment control of the tool allows a user to increase or decrease the impact force. A light source and hand grips improve ease of operation of the tool.

    摘要: An orthopedic impacting tool comprises a motor, an energy storage chamber, a striker, and an anvil. The motor stores energy in the energy storage chamber and then releases it, causing the striker to apply a controlled force on an adapter to create a precise impact for use in a surgical setting. The tool may further comprise a combination anvil and adapter. The tool further allows forward or backward impacting for expanding the size or volume of the opening or for facilitating removal of a broach, implant, or other surgical implement from the opening. An energy adjustment control of the tool allows a surgeon to increase or decrease the impact energy. A light source and hand grips improve ease of operation of the tool.

    摘要: A hydraulic hammer includes a housing defining a cutout and a power cell slidably received within the housing. The power cell includes a valve assembly extending from a side of the power cell. The valve assembly is at least partially received within the cutout of the housing. The hydraulic hammer further includes a pair of wear plates at least partially disposed around the valve assembly of the power cell. Each of the pair of wear plates is coupled to at least one of the power cell and the housing.

    摘要: Device for a hydraulic hammer (1), in which there is a hydraulic impact system and a work point (2) for performing work, for preventing damage caused by ricocheting pieces. The device is formed of a shield (6) that can be lowered to the level of the work point particularly by hydraulic cylinders (7, 8). The shield (6) is formed of an essentially circular jacket, in which recycled materials, for example recycled vehicle tires, transport mats, or similar, are mostly used.

    摘要: A hammer including a housing and a piston arranged for reciprocating movement within the housing is disclosed. The hammer further includes a head assembled on the housing and defining a chamber for holding a pressurized gas and a wall configured to abut the housing and defining a gas discharge passage extending between the chamber and the housing. A plug is positioned in the gas discharge passage and configured to move or deform under pressure of the pressurized gas in the chamber.

    摘要: The disclosed concrete anchor driver tool is coupled to a rotary hammer drill to install a concrete anchor. The tool includes a rod having multi-faceted bolt head end, such as a hexagonal bolt head end, and a socket having a multi-faceted opening in the socket end of the socket. The socket is slipped over the rod and held against the bolt head end of the rod by a compressible spring. The concrete anchor driver tool is operated by coupling the concrete anchor driver tool to a rotary hammer drill, slipping the socket over the concrete anchor, and operating the drill in the hammer mode to hammer the concrete anchor bolt into the concrete. The rotary hammer drill is then put in rotate mode and used to rotate the concrete anchor driver tool rod, which rotates the socket, which, in turn, tightens the nut on the concrete anchor.

    摘要: An electric working machine in one aspect of the present disclosure includes a motor; an acceleration sensor; a load-determiner; a filter part having a cutoff frequency; and a filter-property setting part. The filter part removes an unwanted signal component from a detection signal from the acceleration sensor based on the cutoff frequency and inputs, to the load-determiner, the detection signal with the unwanted signal component removed. The filter-property setting part changes the cutoff frequency of the filter part such that a cutoff frequency in a high-speed rotation mode is higher than a cutoff frequency in a low-speed rotation mode.
