With reference to fig. 5, the three height positions of the heddle frame 2, i.e. the distances between the first height ih 1, the second height ih 2 and the third height ih 3, can be adjusted by adjusting the position of the shedding adjuster 7 on the right swing blade 32, i.e. by changing the position of the swing blade arm 321 at the aforementioned swing blade arm engagement chamber 75 (shown in fig. 4 and 5), and fig. 5 also shows the swinging of the first lifting arm i 111 and the second lifting arm ii 112 about the lifting arm swing axis.

Referring to fig. 6, fig. 6 shows the heald frame 2 at the first height ih 1, when the first lifting arm i 111 and the second lifting arm ii 112 of the lifting arm device 11 (also referred to as "shedding device", as mentioned above) are both at a left position (relative to the position of the lifting arm at the time of heald leveling), the first shedding link i 4 and the second shedding link ii 5 push the shedding transmission conversion device 6 and the shedding adjustment device 7 leftward, so that the right swinging blade 32 swings downward around the revolving shaft, and the heald frame connecting mechanism 3 drives the heald frame 2 downward and is at the lowest position, that is, at the position of the first height ih 1.

With reference to fig. 7, fig. 7 shows the heddle frame 2 in a second level yh 2, i.e. in the uppermost position. When the first lifting arm i 111 is in a left position (relative to the position where the lifting arm is located at the time of heald leveling), the second lifting arm ii 112 is in a right position, the first shedding link i 4 pushes the upper portion of the conversion plate 61 of the shedding transmission conversion device 6 to swing leftward with the connecting pivot of the shedding transmission conversion device 6 and the shedding adjustment device 7 as a swing axis, meanwhile, the second shedding link ii 5 pulls the lower portion of the conversion plate 61 to swing rightward with the connecting pivot of the shedding transmission conversion device 6 and the shedding adjustment device 7 as a swing axis, and the right swing blade 32 swings to a middle position, so that the heald frame 2 is driven by the heald frame connecting mechanism 3 to be in the position of the aforementioned second height ii H2, which is the position where the heald frame 2 is in the middle position.

It should be noted that: when the first heald lifting arm i 111 is in a position deviated to the right (relative to the position where the heald lifting arm is located at the flat level), the second heald lifting arm ii 112 is in a position deviated to the left, the first shedding link i 4 pulls the upper part of the shedding transmission conversion device 6 to swing to the right with the connecting pivot of the shedding transmission conversion device 6 and the shedding adjustment device 7 as a swing axis, meanwhile, the second shedding link ii 5 pushes the lower parts of the shedding transmission conversion device 6 and the shedding adjustment device 7 to swing to the left with the connecting pivot of the shedding transmission conversion device 6 and the shedding adjustment device 7 as a swing axis, the right swing blade 32 swings to the same middle position, and the heald frame connecting mechanism 3 drives the heald frame 2 to still be in the same position of the second height ih 2, namely, the heald frame connecting mechanism is in the same position.

With reference to fig. 8, fig. 8 shows the heddle frame 2 in the position of a third height ih 3. When the first lifting arm i 111 and the second lifting arm ii 112 are both in a position (corresponding to the position of the lifting arm when the heald is in normal operation), the first shedding link i 4 and the second shedding link ii 5 simultaneously pull the conversion plate 61 of the shedding transmission conversion device 6 and the shedding adjustment device 7 rightward to move, so as to push the right swinging blade 32 to swing upward around the rotating shaft (the shaft matched with the right swinging blade shaft hole 325), and the heald frame connecting mechanism 3 drives the heald frame 2 to move upward to be in a third height iii H3, namely, in the highest position.

To sum up, the technical solution provided by the present invention remedies the defects in the prior art, successfully completes the invention task, and faithfully embodies the technical effects mentioned in the above technical effect column by the applicant.
