A device (100) for capturing, centring, gripping and/or securing an object (140) is disclosed. The device comprises a hub (101) and a ring (102) which are concentric and arranged rotatably relative to each other. On the hub there is at least one first control point (111, 111′, 111″), and on the ring there is at least one second control point (112, 112′, 112″), which control points are arranged at different axial levels (151,152). At least one tensioning member (121,122,123) is arranged to interact with the at least one first control point and with the at least one second control point during the rotation, such that the at least one tensioning member is stretched across the air gap (130) in the device. The different axial levels for the at least one first control point and the at least one second control point mean that the at least one tensioning member can freely pass over the at least one first control point during the rotation and can be stretched across the air gap towards the object. Substantially any desired angle of rotation between the hub and the ring can be obtained in this way.

A quick-release bit adapter includes a body having a driving hole extending from a driving section towards a connecting section of the body. The driving section includes a sliding hole extending at a non-parallel angle to and in communication with the driving hole. A resilient positioning member is mounted in the driving section. A releasing device is slideably mounted in the sliding hole. When the releasing device is in a first position, the resilient positioning member is engaged in cuts in an outer periphery of a bit in an engagement position received in the driving hole. When the releasing device is moved to a second position, the bit is disengaged from the resilient positioning member to allow easy removal of the bit.

The present invention relates to a device (1), such as a chuck intended for connection to a drive unit, intended to hold elongated objects (11) such as fishing rod parts in conjunction with surface treatment. The device (1) is comprised of at least one first inner part (9) and at least one outer second part (10) which are pivotally arranged relative to one another between at least one first position where the object (11) can be inserted into the device (1) and at least one second position where the object (11) can be fixed temporarily to the device (1) with at least three elastic bands (14). The present inventions unique feature is that the elastic bands (14) are elongated and that each respective elastic band (14) in one of its other ends is connected to at least one fastening device in the first inner part (9) and that each respective elastic band (14) in its other end is connected to at least one fastening device (13) in the outer second part (10) and that each respective elastic band's (14) distance from the device's (1) center of rotation changes during the relative turning of the first inner part (9) with respect to the second outer part (10) causing the object (11) to be held or released from the device (1) depending on the relative rotational orientation of the first inner part (9) and the second outer part (10).

A clamping assembly for a toolholder includes a toolholder body having an access hole. A locking sleeve is slidably disposed within the access hole and a center collet is disposed within the locking sleeve and is fixedly connected to the toolholder body. The center collet receives a retaining tip of a tool. A spring assembly and a release device cause the locking sleeve to move within the access hole between a load position, where the locking sleeve is disengaged from the center collet such that the center collet is open and a lock position, where the locking sleeve engages the center collet such that the center collet is closed and locks the retaining tip of the tool within the access hole.

A cutter-tooling assembly has a tool holder, a positioning chunk, a cutter and a collet. The tool holder has a through hole axially formed through the tool holder. The positioning chunk is screwed in the through hole and has a cavity. The cavity has multiple corners formed around an inner surface of the cavity. The cutter is inserted into the through hole and has multiple edges abutting the corners. Because the cross sectional shape of the cavity is multilateral and has multiple corners which the edges abut, the combination of the corners and the edges can prevent a relative rotation between the tool holder and the cutter and make the cutter securely connected with the tool holder.

A device for gripping a treatment tool of a handpiece is provided that can firmly grip the treatment tool and achieve a high vibration absorbing property. The device for gripping a treatment tool of a handpiece includes: a spindle rotatably installed; and a coil spring that is set in the spindle and rotated integrally with the spindle, the treatment tool inserted from a tip of the spindle into the coil spring being gripped by an inner diameter surface of a grip portion of the coil spring, and the coil spring has an inconstant natural frequency. Preferably, the coil spring includes the grip portion in a middle region thereof, and the grip portion has a smaller inner diameter than that of other regions.

Retaining device for a wheel-alignment analyzer for attachment to a wheel of a motor vehicle. Retaining device has a retaining element having at least three retaining arms and a clamping mechanism which can be displaced along the retaining arms. The ends of the clamping mechanism are provided with an overlapping portion for overlapping the edge of the rim and the retaining element can be secured to the edge of the rim. The retaining device offers a stable engagement and centering solution, thus permitting a correct wheel-alignment analysis. The overlapping portion may be spring-loaded and biased in the direction of the wheel and/or the clamping mechanism, and a spacer and the overlapping portion may be provided on the spacer.

A chuck has an attachment device for attaching the chuck to a machine spindle and a collet with clamping jaws defining an insertion opening at an end of the chuck opposite the attachment device. A sliding sleeve surrounds the clamping jaws and is axially moveable into a clamping position for clamping a machining tool inserted into the insertion opening and into a release position for releasing the tool. Between an inner circumference of the sliding sleeve and an outer circumference of the clamping jaws a contact path conically tapering in an axial direction and counter pressure members that engage positively the contact path are provided. The contact path is positioned at a slant relative to the axial longitudinal center of the collet. The slant angle is so small that under expected operating forces a self-locking action between contact path and counter pressure members is maintained at all times.
