One end of the bottom of the impact member 50 far from the limit seat 53 is provided with a rotating seat 55, and a pin rod 54 is rotatably arranged at the rotating seat 55.
[0037] Please refer to Figure 9 and Figure 10, the triangular seat 10 is further provided with a rotating slot 510, the rotating slot 510 is communicated with the second moving hole 58, both ends of the pin rod 54 are rotatably installed in the rotating slot 510, and the height of the limiting block 52 gradually decreases from the center to the edge. In this embodiment, the cross-section of the telescopic hole 59 is circular, the cross-section of the second moving hole 58 is rectangular, and the diameter of the telescopic hole 59 is smaller than the width of the second moving hole 58.
[0038] Please refer to Figure 7 , a telescopic hole 59 is provided at the bottom of the second moving hole 58, a limiting hole 56 is further provided at the bottom of the limiting seat 53, one end of the elastic element 57 abuts against the bottom of the telescopic hole 59, and the other end of the elastic element 57 abuts against the bottom of the limiting hole 56. The elastic element 57 in this embodiment is used to provide elastic support for the impact member 50, so that the impact member 50 returns to the initial position after being forced to swing downward each time.
[0039] In this embodiment, a first middle plate jacquard triangular block 20, a second middle plate jacquard triangular block 21 and an adjusting jacquard triangular block 30 are further installed on the top of the triangular seat 10. A plurality of mounting holes are provided in the first middle plate jacquard triangular block 20, the second middle plate jacquard triangular block 21, the adjusting jacquard triangular block 30 and the anti-collision jacquard triangular block 40.

[0043] Please refer to Figure 11, when the present utility model is working on a transfer jacquard machine, after the knitting needle makes a lateral needle exit on the jacquard selector cam of the jacquard machine, it hits the pre-planned impact area, causing the impact member 50 to rotate through the pin rod 54. As a result, the elastic element 57 at the bottom of the impact member 50 deforms and finally rebounds, generating a rebound effect, thereby providing a buffer force for the knitting needle and reducing the wear of the knitting needle of the transfer jacquard machine.
[0044] The present utility model can complete three actions of tucking / looping / float without replacing the triangular jacquard. By movably arranging the impact member 50, when the knitting needle operates under computer adjustment, it can avoid colliding with the interference part of the impact member 50.
[0045] When the computerized flat knitting machine selector controls the knitting needles to synchronously perform the looping and float actions, mechanical collisions may occur due to the intersection of the movement trajectories. By adopting the present utility model, a buffer stroke can be set to provide phase difference compensation for the movement of the knitting needles, thereby reducing the wear probability of the knitting needles of the transfer jacquard machine and prolonging the service life of the product.
[0046] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
