AI Technical Summary
The existing crank-type jacquard machine's tie rod structure is prone to loosening when the adjusting nut is vibrated, resulting in unstable bearing seat position, affecting the equipment's accuracy and normal operation.
The design employs a combination of a drive nut, a limiting component, and an elastic component. The elastic component pushes the limiting component against the tightening nut to prevent it from loosening. When adjustment is needed, a snap-fit connector is used to adjust the bearing seat spacing.
This effectively prevents the spare nut from loosening, ensuring the accuracy and normal operation of the equipment. At the same time, it facilitates the adjustment of the bearing seat spacing, ensuring the stability and ease of operation of the equipment.

Abstract
Claims
1. A lever structure for a crank-type jacquard machine, comprising an adjusting screw (1) and tightening nuts (2) threaded to both ends thereon, and bearing seats (3), wherein the threads at both ends of the adjusting screw (1) are in opposite directions, and a driving nut (4) is fixedly connected to the center of the adjusting screw (1), characterized in that: The top and bottom ends of the drive nut (4) are provided with limiting members (5) to prevent the rotation of the tightening nut (2). The two limiting members (5) are detachably connected by a connector (6), which is sleeved on the drive nut (4).
2. The pull rod structure of a crank-type jacquard machine according to claim 1, characterized in that: Several elastic elements (7) arranged in a ring array are fixedly connected to the top and bottom ends of the drive nut (4). The end of the elastic element (7) away from the drive nut (4) is fixedly connected to the limiting member (5). The elastic element (7) has elastic potential energy to push the limiting member (5) toward the tightening nut (2).
3. A draw bar structure for a crank jacquard according to claim 2, characterized in that: The limiting member (5) has several grooves (8) on the side facing the pre-tightening nut (2), and several protrusions (9) corresponding to the grooves (8) are fixedly connected to the pre-tightening nut (2).
4. A draw bar structure for a crank jacquard according to claim 3, characterized in that: Several grooves (8) are arranged in a ring array on the limiting member (5), and the cross-section of the grooves (8) is triangular.
5. A draw bar structure for a crank jacquard according to claim 1 or 2, characterized in that: The number of the connectors (6) is two, and both connectors (6) are connected to the corresponding limiting members (5) through several connecting plates (10). The several connecting plates (10) are arranged in a ring array, and the two connectors (6) are detachably connected to each other.
6. A draw bar construction for a crank jacquard according to claim 5 wherein: At least two symmetrically distributed snap-fit pieces (11) are fixedly connected to one of the connectors (6) on the side facing the other connector (6), and the other connector (6) has a slot that matches the snap-fit piece (11).
