[0058] In other possible embodiments, the first drive assembly 40 and the second drive assembly 50 may also be in the form of drive chains such as other linear motors, motor screws, etc.

[0059] The working principle of this embodiment is as follows: The rotational movement of the first motor 401 to the sixteenth motor 508 drives the first gear 409 to the sixteenth gear 516 to rotate. The rotational movement of the first gear 409 to the sixteenth gear 516 can drive the first rack 61 to the sixteenth rack 78 to move linearly, thereby driving the first output connecting arm 11 to the sixteenth output connecting arm 29 to move linearly.

[0060] By controlling the regular rotation of the motor, the first output connecting arm 11 to the sixteenth output connecting arm 29 can be controlled to make regular linear motion, thereby driving the heald frame device on the standard loom equipment to make regular motion. Embodiment 2

The driving mechanism is correspondingly connected to the heald frames 80, and the driving mechanism drives the heald frames 80 to rise and fall.

[0063] like Figure 8 As shown, the working principle of this embodiment is as follows: The electronic opening device transmits power to the second rocker arm 97 through the second connecting rod 98 and the loom connecting arm 99. The second rocker arm 97 transmits power to the first rocker arm 94 through the first connecting rod 95. The swing of the first rocker arm 94 drives the first heald frame connecting rod 91 to produce reciprocating lifting motion. The swing of the second rocker arm 97 drives the second heald frame connecting rod 92 to produce reciprocating lifting motion, so that the heald frame 80 performs reciprocating lifting motion.
