Slide hammer weights
A slide hammer tool including a shaft having first and second opposing ends, a handle slidably coupled to the shaft, and a slide hammer weight assembly removable coupled to the handle via threaded fasteners. The slide hammer weight assembly including a number of slide hammer weights coupled together.
Tool bushing, breaking hammer and mounting method
A tool bushing of a breaking hammer, a tool bushing arrangement, a breaking hammer and a method of mounting a tool bushing of a breaking hammer are disclosed. The tool bushing is a sleeve-like piece having a multi-shouldered outer surface with three or more successive cylindrical portions. The cylindrical portions have different diameters that match with corresponding surfaces of a bushing housing when the tool bushing is mounted. Diameters of the bushing and the bushing housing are dimensioned so that friction forces are generated when the bushing is assembled.
SLIDE HAMMER WEIGHTS
A slide hammer tool including a shaft having first and second opposing ends, a handle slidably coupled to the shaft, and a slide hammer weight assembly removable coupled to the handle via threaded fasteners. The slide hammer weight assembly including a number of slide hammer weights coupled together.
HYDRAULIC BREAKER
The present invention relates to a hydraulic breaker comprising: a back head having a gas chamber provided therein; a cylinder disposed at the lower part of the back head, and having a hydraulic passage and a hydraulic space; a front head disposed at the lower part of the cylinder; a chisel provided inside the front head; a piston provided to reciprocate in the cylinder so as to hit the chisel; and a breaker main body having a plurality of penetration bolts integrally connecting the back head, the cylinder, and the front head, wherein the back head of the breaker main body is provided with a control valve for supplying and blocking hydraulic pressure to/from the hydraulic passage and the hydraulic space.
TENT PEG HAMMER ASSEMBLY
A hammer assembly has a guiding unit, an impacting block, and a fastening assembly. The guiding unit is elongated and has a body, a limiting portion, and a limiting unit. The body has a first end and a second end opposite the first end of the body. The limiting portion is disposed at the first end of the body. The limiting unit is disposed closely to the second end of the body. The impacting block is movably mounted around the body of the guiding unit and blocked by the limiting portion and the limiting unit of the guiding unit. The fastening assembly has a fastening seat connected with the second end of the body. The fastening seat has a positioning structure for fastening a tent peg. The positioning structure may be a receiving recess or a threaded hole.
STRIKING IMPLEMENT CAP
A striking cap that may include a distal end configured to strike a foreign object. The striking cap may also include a proximal end opposite the distal end. The proximal end may include a protruding ring, where the protruding ring forms a cavity. The cavity may be configured to enable the striking cap to be attached to a striking implement. The proximal medial edge of the protruding ring may include a beveled surface.
Hand Tool with Replaceable Handle
A tool, such as a hammer including a handle configured to be replaceable is shown. In one embodiment, the handle includes a grip insert coupled to the shaft of the hammer and an outer grip surrounding the grip insert. In another embodiment, the hammer includes a shaft with a pair of opposing channels. The handle includes a grip insert with a pair of corresponding projections to couple to the pair of opposing channels and an outer grip surrounding the grip insert.
Breaking hammer and method of supporting percussion piston
A hydraulic breaking hammer and method of supporting a percussion piston is provided. The breaking hammer includes a percussion device provided with a reciprocating piston. The piston is supported on a frame at its end portions by a first piston bearing element and a second piston bearing element. The second piston bearing element includes a collar sealing element facing towards a working collar of the piston. The piston bearing elements are easily mountable and dismountable separate components.
Power tool having an intermediate housing
A power tool is provided including a motor housing; a transmission housing disposed adjacent the motor housing with a gap therebetween; an electric motor including a rotor and a stator mounted within the motor housing; and an intermediate housing disposed between the electric motor and the transmission mechanism. The intermediate housing includes a back wall extending radially adjacent an axial end of the stator and having a through-hole therein through which the motor spindle extends; side walls extending axially from an outer circumference of the back wall internally of the motor housing; and one or more external walls extending substantially-radially outwardly from axial end of the one or more side walls to fill a gap formed between the transmission housing and the motor housing in the axial direction.
BREAKING HAMMER AND METHOD OF SUPPORTING PERCUSSION PISTON
A hydraulic breaking hammer and method of supporting a percussion piston is provided. The breaking hammer includes a percussion device provided with a reciprocating piston. The piston is supported on a frame at its end portions by a first piston bearing element and a second piston bearing element. The second piston bearing element includes a collar sealing element facing towards a working collar of the piston. The piston bearing elements are easily mountable and dismountable separate components.
