In the embodiment, the jacquard device realizes the working principle of three stations:

the swing amplitude of the double-station jacquard device is a slot needle position, and the swing amplitude of the three-station jacquard device is two slot needle positions (two needle pitches) due to the addition of a station state, namely: without traversing, its swing is two grooved pins (two pitches).

Referring to fig. 1, 2 and 3, the jacquard device of the three-station is referred to as a jacquard device in which the guide needles 122 can accurately rest at the intermediate position (refer to fig. 3, namely, the position of the second station 22) in addition to swinging left and right.

Referring to fig. 1, 2 and 3, the jacquard device of the double station can only swing left and right, the stop position is fixed and accurate, and the fixed and accurate is that after the tooth groove 15 of the bottom base is grooved according to the calculated data, the left swing or the right swing of the yarn guide needle 122 can stop on the tooth wall, and the needle position is correct as long as the tooth wall distance is correct because the tooth wall distance is calculated. The piezoelectric ceramic plates can generate swinging moment after being charged, the complete piezoelectric ceramic plates capable of swinging left and right are formed by bonding two single piezoelectric ceramic plates on a glass fiber plate in a combined mode, each single piezoelectric ceramic plate is responsible for one swinging direction, namely one single piezoelectric ceramic plate is charged and the other single piezoelectric ceramic plate is discharged, namely correct swinging moment can be generated, and the piezoelectric ceramic plates swing leftwards or rightwards, which is the basic swinging principle of the piezoelectric ceramic plates.

Since the second limiting portion 202 limits the needle blocking portion 14, the needle blocking portion 14 can only swing between the second limiting portion 202 and the third limiting portion 203.

Referring to fig. 1, 2 and 3, the second piezoelectric ceramic sheet 131 is provided longer in order to increase the moment of the second piezoelectric ceramic sheet 131, and the moment of the second piezoelectric ceramic sheet 131 is greater than that of the lower layer due to the need to implement three stations.
