摘要： An improved structure of multi-functional hand tool, wherein, a pushing axle rod is screw connected with a chuck, a pushing axle rod is screw connected with a driving rod; bearings are slipped over a positioning sleeve, then the positioning sleeve, the pushing axle rod and the chuck are together placed in a pipe body with the bearings. The positioning sleeve can be rotated in the bearings. A front cover is locked in the front end of the pipe body; the chuck is extended out of the front cover. The pushing member is screwed in the pipe body to render a hole on a rear enlarged threaded portion of the pushing member to be exactly located at a position limiting slot of the pipe body. The external sleeve then is slipped over the pipe body, and an inner screw hole of the external sleeve is aligned with the position limiting slot of the pipe body. Then the positioning screw rod is screwed in the inner screw hole to extend through the position limiting slot and the hole of the pushing member. Thereby, the external sleeve pushes the pushing member when the external sleeve is rotated; the pushing member in turn moves the chuck into/out of the positioning sleeve to thereby insert/take a grinding member into/out of the chuck.

摘要： A tool bit chuck for a bit (1) having axially extending latching grooves (2) closed at the opposite ends spaced apart in the axial direction, and axially extending rotary entrainment grooves (3) open at the trailing end of the bit. The chuck has entrainment elements (8) and radially displaceable latching elements (8).

摘要： A self-tightening drill chuck adapted to be mounted on a drill spindle for rotation about and reciprocation along the axis of the spindle has a guide body rotatable on the spindle about the axis and formed with a plurality of jaw guides inclined relative to the axis and spaced angularly thereabout and formations axially fixing the guide body on the spindle against substantial relative axial displacement. Respective jaws displaceable in the guides are formed with radially directed teeth meshing with a screwthread of an adjustment body fixed on the spindle against rotation thereon so that rotation of the adjustment body relative to the guide body in one direction displaces the jaws radially toward one another and opposite rotation displaces the jaws radially apart. Further formations secure the adjustment body on the spindle for limited relative axial displacement substantially greater than the relative axial displacement possible between the guide body and the spindle.

摘要： A drill chuck can be driven by and rotated with a drill spindle. The drill chuck has an axial passage through which the impact effort of a central anvil shaft can be transferred to the drill. The drill can be held in chuck jaws, the movement of which can be controlled by a control sleeve. For connecting the drill chuck at the drill spindle in such a way that they rotate together, there is provided a coupling element and this can allow an axial displacement of the drill chuck at the drill spindle. This mode can be turned off, or on, by use of a locking mechanism and with a coupling ring. The lock mechanism includes a lock element which is axially fixed with respect to the drill spindle, which can be actuated by the coupling ring. The coupling ring can be axially shifted but it can be fixed so as not to rotate. The lock element can be moved into respective recesses arranged circumferentially at the chuck body for precluding axial displacement of the chuck body. The coupling ring has teeth which can engage in matching teeth of the control ring.

摘要： A tool chuck for securing a tool bit in a drilling and cutting device includes a guide tube into which the tool bit is inserted and an adjusting sleeve displaceable relative to the guide tube. The guide tube has spaced first and second apertures with the first apertures holding locking members and the second apertures holding entrainment strips. The adjusting sleeve has alternating first and second pockets in its inside surface for receiving the locking members and the entrainment strips. With a tool bit having slots for both the locking members and the entrainment strip, both the locking members and entrainment strips can be displaced radially inwardly by the adjusting sleeve. If the tool bit has only slots for the locking members, the locking action can be effected with the entrainment strips maintained radially outwardly from the tool bit.
