摘要： It is an object of the invention to reduce noise caused by run-out of a tool bit in an impact tool. The representative impact tool according to the invention includes a tool holder 137 that houses a tool bit 119 in such a manner that the tool bit can linearly move in its axial direction, and a barrel 108 that is integrally connected to the tool holder 137 The impact tool further includes an elastic element 155 that is disposed between an inner circumferential surface of the tool holder 137 and an outer circumferential surface of the tool bit 119 in an end region of the tool bit 119 on the barrel side and connected in close contact with the tool holder 137 and the tool bit 119 over a predetermined length of the tool bit 119 in the axial direction. The elastic element 155 applies a biasing force to prevent a run-out of the tool bit 119 in a direction transverse to the axial direction. Further, an intermediate element 145 comes in point contact with the tool bit 119 on its axial center line.

摘要： The invention relates to a percussive tool having an oscillatory drive (3), the force of which is transmitted to a tool bit holder (25) by way of a drive member (17). Extending through the percussive tool is a longitudinal opening that allows a rod-shaped object, such as, for example, a guide wire, to be guided through the percussive tool. The tool bit holder (25) has a seat (34), which can receive the tool bit in different orientations. Moreover, the tool bit holder (25) is made of a combination of light metal and steel, which allows a reduction in acceleration forces and noise generation. A saddle-shaped coupling (24) is provided between the tool bit holder (25) and the drive member (17), which guarantees a tight fit.

摘要： A tool assembly (10), for example a hydraulic or pneumatic hammer assembly, includes a housing (11) defining a chamber (16), a removable reciprocating work tool (20) arranged in the chamber, and a tool retention member (80) having an aperture through which the work tool extends. The housing (11) includes an engaging structure (50) which permits the engagement of the tool retention member (80) with the housing by relative rotation of the tool retention member and housing. The work tool (20) is provided with retention structure (44) such as a retaining flange which prevents the removal of the work tool from the housing when the tool retention member is engaged with the housing. At least some of the disclosed embodiments may eliminate the need for a retainer pin, thereby allowing the work tool to rotate, possibly avoiding wear, increasing tool life and simplifying tool replacement.

摘要： A pneumatic hammer drill includes: a pneumatic cylinder having a cylinder rear end fitted in a handle body, an air passage, and a pressure chamber; and an air valve adjacent to the cylinder rear end. The air valve has a front bearing end, a valve orifice interconnecting fluidly the air passage and the pressure chamber, and an opening disposed at the front bearing end in communication with the valve orifice. A piston is disposed slidably in the pressure chamber, and has a piston rear end capable of moving towards or away from the front bearing end. An air trap arrangement is associated with the piston rear end and the front bearing end to trap air between the same and around the opening so as to provide a shock-absorbing air cushion when the piston rear end moves towards the front bearing end.
