[0027] In addition, when the mobile unit needs to be connected, the staff adjusts the angle of the circular mounting rod appropriately by adjusting the handle to ensure that after the circular mounting rod moves downward, the octagonal connecting block can be accurately inserted into the output shaft of the servo motor, and then pulls the two movable limit frames outward. When the two movable limit frames are separated from the inclined limit slots, the circular mounting rod can automatically move downward. At this time, the octagonal connecting block is inserted into the output shaft of the servo motor, and the bottom of the two stabilizing pins are inserted into the two circular grooves, making the mobile frame more stable when used.

[0028] 2. According to the present invention, when the row of rubber anti-slip sleeves on the front side is full of yarn, the staff presses the button on the control panel. At this time, the output shaft of the servo motor rotates half a circle, realizing automatic rotation of the yarn placing rack, and the row of yarns after rotation is right behind, which is convenient for the staff to place the yarn to be placed on the side corresponding to the row of yarns, so that the force on the yarn placing rack is more even, avoiding serious uneven force on the yarn placing rack; when the detection button is pressed, when the staff presses the button on the control panel again, the output shaft of the servo motor can rotate half a circle; when the detection button is not pressed, when the staff presses the button on the control panel again, the output shaft of the servo motor remains stationary, avoiding the row of yarns after placement from moving to the front side again, which is beneficial to improving the adjustment effect of the yarn placing rack;

[0029] In addition, when the front and rear rows of rubber anti-slip sleeves are full of yarn, the staff rotates the yarn placing rack forty-five degrees clockwise or counterclockwise by adjusting the handle, and the output shaft of the servo motor is in a powered and non-rotating state under the control of the control panel. When the yarn placing rack rotates forty-five degrees clockwise or counterclockwise, the yarn placing rack pushes the four movable positioning rods to automatically move upward. When the yarn placing rack is rotated to the appropriate angle, the four movable positioning rods are automatically reset under the action of four reset springs B; when the staff rotates the adjusting handle forty-five degrees clockwise or counterclockwise, one of the pressing plates can automatically press the detection button. At this time, when the staff presses the button on the control panel again, the output shaft of the servo motor can rotate half a circle. On the premise of achieving symmetrical placement of the yarn, there will be no misadjustment, thereby ensuring the adjustment accuracy of the yarn placing rack. BRIEF DESCRIPTION OF THE DRAWINGS
