[0006] The present invention is further configured such that: both the upper beam assembly and the lower beam assembly include a crossbeam, a heddle rod is provided at the bottom of the crossbeam, fastening bolts are provided through both ends of the crossbeam, a pad is bolted to the end face of each of the two fastening bolts, a spring is bolted to the surface of each of the two pads, and the spring is sleeved on the end face of the heddle rod.

[0007] The above technical solution facilitates the use of the installed spring to fix the position of the heddle rod, while the heddle rod is used to pass the yarn through the heddle wires, so that the yarn is arranged on the heddle frame according to a predetermined pattern. At the same time, the external setting makes it convenient for disassembly and replacement in the future.

[0008] The present invention is further configured such that: the lower beam assembly has multiple external hooks evenly bolted to the side of the crossbeam away from the heddle rod.

[0009] The above technical solution facilitates the lower beam assembly to drive the outer hook to lift the fabric, and also makes processing operations easier.

[0010] The present invention is further configured such that: a plurality of central support reinforcing blocks are evenly bolted to the middle position of the crossbeam along the length direction.

[0011] The above technical solution facilitates the use of central bracing reinforcement blocks to enhance the strength of the entire crossbeam, thereby ensuring that the crossbeam maintains its strength and stability during long-term use.

[0012] The present invention is further configured such that: a plurality of connecting blocks are evenly bolted to the side of the crossbeam near the heddle rod, and the crossbeam is bolted to the heddle rod through the plurality of connecting blocks.

[0013] The above technical solution facilitates the use of multiple connecting blocks to install and fix the position of the heddle rod, and also makes it convenient to replace it later on the outside of the loom.

[0014] The present invention is further configured such that: both ends of the crossbeam are provided with adaptive openings, and the openings are adaptively closed by fastening bolts.

[0015] The above technical solution facilitates the installation of the spring clip by ensuring that the opening can be closed under the tightening action of the locking bolt, thereby improving the installation stability of the spring clip.

[0016] The present invention is further configured such that: the spring piece is L-shaped and has a through hole on its vertical surface, and is sleeved on the outer wall of the heddle rod.

[0017] The above technical solution facilitates the use of spring clips to fix the position of the installed heddle rod, and improves the stability of the heddle rod during use.

[0018] The beneficial effects of this utility model are as follows: 1. The external heddle frame structure for a shuttle loom proposed in this utility model is connected to the outside of the shuttle loom via a side frame, which avoids spatial interference with the original internal components of the shuttle loom and ensures the smooth progress of the gauze weaving process; 2.
