However, there are problems with this construction. Firstly, a metal wire resetting structure is adopted, and due to the fact that the metal wire is good in rigidity and large in elastic coefficient, the metal wire can be bent only by overcoming large elastic force after a warp thread penetrates through a thread penetrating part, and in turn, a jumper bar can generate excessive tension on the warp thread, and the warp thread is easy to break; secondly, a metal elastic sheet resetting structure is adopted, the metal elastic sheet and a metal wire are connected and need riveting and pressing processes, and due to the fact that the size of parts is small, assembly is inconvenient.

In order to achieve the above purpose, the utility model adopts the following technical scheme: circular loom jumper bar, including the conducting rod body and insulating support, on the insulating support was fixed in the conducting rod body, be equipped with the elasticity portion that resets on the insulating support, elasticity portion and the conducting rod body electric conductance that resets, the elasticity portion that resets is including the connecting rod body and compression spring, the one end of the connecting rod body is fixed in insulating support, the other end of the connecting rod body inserts compression spring's one end interference fit fixed, compression spring's the other end is used for propping the butt circle of circular loom and produces elasticity, the circular loom jumper bar relies on the elasticity after compression spring is compressed to reset.
Further, the other end of the compression spring is a large-diameter end with a larger diameter.
Furthermore, the other end of the compression spring is provided with an arc-shaped structure matched with the periphery of the abutting ring.
Further, the length of the connecting rod body inserted into the compression spring is not less than 5 mm.
Furthermore, the connecting rod body is provided with a bending end, the bending end extends towards the abutting ring and is inserted into the compression spring for interference fit fixation.
Furthermore, the connecting rod body and the conductive rod body are of an integrated structure.
After the technical scheme is adopted, the utility model has the advantages of as follows: compression spring pegs graft with the body of rod of connection, and it is very convenient to assemble, and simultaneously owing to be interference fit, compression spring's one end produces certain elasticity because being propped open by the body of rod of connection slightly, can reach the pretension effect to can be connected more reliably with the body of rod of connection, compression spring does not have the risk that drops, and the reliability of use improves greatly.
