A support structure for a heating or cooling system includes a plurality of projections designed to be capable of retaining one or more thermal elements positioned adjacent thereto. The projections are positioned so as to form a first set of substantially parallel undulating channels, each channel having one of the projections forming at least a part of the inner radius of each undulation, with each projection having a recess formed in a side wall thereof facing said channel. The undulations of the channel ensure that a thermal element positioned in the channel will make contact with the projections each time it has to bend around one, without requiring spacing of the projections to squeeze the thermal element. The thermal element can thus be held securely without any play (unwanted lateral movement) in a channel that is slightly wider than the thermal element. Recesses in the channels at the contact points also restrict movement in the vertical direction, thus preventing the thermal element from ‘popping out’ of the channel, while not requiring any restriction narrower than the thermal element.

The inner wall face of the locking sleeve is provided with a containing groove, an abutting part and a positioning groove. When the locking device is located at the locking position, the locking piece is pushed by the abutting part to be tightly pressed in the locking groove of the hollow rod so as to limit the grip to rotate relative to the hollow rod, and the positioning set abuts against the inner wall face of the locking sleeve. When the locking device is located at the releasing position, the locking piece is separated from the abutting part and can move between the containing groove and the locking groove, so that the grip can rotate relative to the hollow rod, and the positioning set is connected to the positioning groove in a clamped mode. Therefore, the positioning group provides a positioning effect relative to the grip when the locking device is at the release position.
