A clamp device includes: a tool spindle including a protrusion; an additive-manufacturing head having a recess into which the protrusion is inserted in a first direction, the additive-manufacturing head being detachably coupled to the tool spindle; and a clamp mechanism portion that clamps mutually the recess and the protrusion inserted into the recess. The additive-manufacturing head includes a pin member. A pin insertion hole into which the pin member is inserted in a second direction intersecting the first direction is made in the tool spindle.

A rotary positioning device includes a base, a fixing seat assembled on the shaft and stopper of the base and having and a movable positioning body respectively placed in each horizontal through-hole thereof, a rotation unit including a driving member and a rotating member and assembled outside the fixing seat, the driving member including a rotating shaft movably installed inside the protruding shaft portion of the fixing seat and a connecting portion located on one side of the rotating shaft, the rotating member including two inner shoulders that rotate and resist or retreat from the clamping portion of the fixing seat and two pushing portions for pressing the respective movable positioning bodies for lateral displacement in each through-hole, and an elastic member placed between the protruding shaft portion of the fixing seat and the rotating shaft of the driving member.

A securing element for securing a spindle in a bushing, in particular for a medical stand device, includes a supporting portion configured to arrange the securing element in a predefined axial position on a supporting apparatus of the stand device, and an engagement portion configured to interact with a spindle rotatably supportable about an axis of rotation in the supporting apparatus, or a pin of the stand device, to secure the spindle or pin in a predefined axial position relative to the supporting apparatus rotatably within the supporting apparatus. The securing element can be supported in at least one radial position on the supporting apparatus, in particular in a mounting preparation position and/or a securing position, wherein the engagement portion is configured to interact with the spindle or the pin by engagement in the radial direction, in particular in the securing position. The securing element may also be secured in several radial positions and comprise coupling portions that are formed correspondingly. Also disclosed are components correspondingly formed to the securing element, in particular a supporting apparatus, a cover for the supporting apparatus, and a coupling element; and a securing system, or a securing mechanism, or a mounting set each comprising at least one securing element according to the invention.

A first rod (21) is inserted into a first guide hole (11) so as to be movable in a vertical direction. A second rod (22) is inserted into a second guide hole (12), which crosses the first guide hole (11), so as to be movable in a horizontal direction. An accommodation groove (31) is disposed in a lower half portion of the first rod (21). The second rod (22) is provided with an insertion portion (32) to be fitted in the accommodation groove (31). A cam groove (38) provided in the insertion portion (32) is fitted over a pin (35) provided in the lower half portion of the first rod (21). A driving means (D) connected to the second rod (22) moves the second rod (22) in the horizontal direction.

A lateral positioning device coupled to a first object to laterally engage or interfere with a second object. The lateral positioning device includes a body portion and positioning element. The body portion is coupled to the first object in a first direction and has a through hole which has therein a limiting portion and extends in a second direction, with an angle formed between the first and second directions. The positioning element is penetratingly disposed in the through hole and limited by the limiting portion to thereby move in the second direction. The positioning element has an engaging portion disposed on the first side of the limiting portion to allow the engaging portion to engage with the second object; a stopping portion disposed on the second side of the limiting portion; and a neck portion connecting with the engaging and stopping portions and passing through the limiting portion.

The invention relates to an arrangement comprising an energy storage module, a module carrier, particularly a vehicle body, and a ball lock bolt for fastening the energy storage module on the module carrier.

A locking mechanism includes a lock housing and an activation shaft. The lock housing defines first and second axes, each being different than the other. The lock housing includes an inner mechanism housing wall, a hollow conduit defined by the inner mechanism housing wall, and a channel. The channel is defined by a portion of the inner mechanism housing wall and has first and second portions, where the first portion extends along the first axis and the second portion extends along the second axis. The activation shaft is at least partially surrounded by the hollow conduit and includes a shoulder protruding from the activation shaft towards the channel of the inner mechanism housing wall. In an unlock position, the shoulder is freely manipulatable within the first portion of the channel along the first axis, and in a lock position the shoulder is prevented from moving along the first axis.

A ball bearing connector is provided, comprised of a setting tool further comprised of several steel balls which are biased either inwardly or outwardly by means of a biasing member. An easily interchangeable drill stop further comprised of an annular recession is position into or over the setting tool, and the balls located thereon fit in the annular recession to provide a releasable snap-fit connection between the drill stop and the setting tool.

A lock mechanism includes a snapping part and a pressing part configured to be slidably connected with a first body. The pressing part includes a pressing end and an abutting end opposite to the pressing end. The abutting end is configured to abut against the snapping part to make the snapping part engage with a second body and to lock the second body onto the first body.
