When in use, it needs to continuously open and contract to change the distance between the jaws to achieve the effect of clamping the yarn. However, during the opening and closing process, the jaw surfaces of the projectile yarn clamp continuously collide, which not only causes increased wear on the jaw surfaces, but also easily causes breakage at the connection between the jaws and the two arms. Therefore, it is necessary to design a shock-absorbing projectile yarn clamp for a projectile loom to solve the above problems.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0037] Through the above-mentioned protective mechanism, the left and right arms 3 of the shuttle yarn clamp are opened, the T-block 6 is inserted into the T-hole 7, and the power shaft 9 is rotated so that the tightening block 8 abuts against the top and bottom of the mounting block 4. In this way, the protective mechanism is fixed to the shuttle yarn clamp. When the shuttle yarn clamp is merged, the distance between the left and right arms 3 is reduced, thereby squeezing the spring 12, so that the jaws on the left and right arms 3 can be avoided from directly colliding, the wear of the jaws can be reduced, and the left and right arms 3 can be effectively protected.

[0038] Specifically, the assembly unit includes an inner support 13, a slide 14, a positioning block 15 and a connecting rod 16.

[0042] Specifically, the side surface of the assembly block 5 contacts the installation block 4 , and the side surface of the T-shaped plug-in block 10 contacts the assembly block 5 . It should be noted that the assembly block 5 and the T-shaped plug-in block 10 can be limited.

[0043] Specifically, the inner cavity is communicated with the slot 11 , which facilitates the positioning block 15 to be inserted into the positioning groove 17 .

[0044] Specifically, a first mounting hole is provided on the head 1 and a second mounting hole is provided on the shoulder 2. It should be noted that this facilitates the installation of the projectile yarn clamp on the projectile loom.

When the projectile yarn clamp is merged, the distance between the left and right arms 3 is reduced, thereby squeezing the spring 12, thereby avoiding direct collision between the jaws on the left and right arms 3, reducing the wear of the jaws, and effectively protecting the left and right arms 3.

[0047] S2: When assembling the protective mechanism, the pressing block 8 will drive the slide plate 14 to move, and the slide plate 14 will drive the connecting rod 16 to rotate, so that the positioning block 15 can be moved vertically and inserted into the positioning groove 17 to limit the T-shaped plug block 10. The protective mechanism is easy to assemble, and the spring 12 on the assembly unit is easy to remove, which is convenient for later maintenance and replacement.
