When the large circular knitting machine body needs to be fixed, the staff pushes the large circular knitting machine body between the two clamping blocks, and then drives the two connecting plates to move closer to each other through the driving assembly, so that the two clamping blocks cooperate and clamp the base, reducing the probability of displacement of the large circular knitting machine body and improving the stability of the large circular knitting machine body.

[0007] Furthermore, the driving assembly includes a driving motor fixed to the side wall of the mounting seat, the output shaft of the driving motor passes through the side wall of the mounting seat and is rotatably connected, the driving assembly also includes a double-headed screw fixed to the end of the output shaft of the driving motor, the end of the double-headed screw away from the output shaft of the driving motor is rotatably connected to the inner wall of the slide groove, the double-headed screw is provided with two sections of threads with equal pitch and opposite rotation direction, and the two connecting plates are respectively threadedly connected to the two sections of threads of the double-headed screw.

[0008] By adopting the above technical solution, when the two connecting plates need to be moved, the staff only needs to start the driving motor to drive the double-headed screw to rotate. Since the two connecting plates are threadedly connected to the two sections of threads on the double-headed screw, the two connecting plates are slidingly connected to the inner wall of the slide groove, so that the two connecting plates are moved closer to each other, making it easier for the two clamping blocks to cooperate and clamp the base.

The universal wheel 4 is fixed to the bottom plate of the base 1, and four universal wheels 4 are provided and distributed in a rectangular array. The connecting plate 5 is a rectangular plate-shaped structure, and the connecting plate 5 is arranged in the slide groove 31 and is slidably connected to the slide groove 31, and the connecting plate 5 is symmetrically provided with two. Two tightening blocks 6 are provided, and the two tightening blocks 6 are respectively fixed to the side walls of the two connecting plates 5 away from the mounting seat 3.

[0030] The driving assembly 7 is mounted on the mounting seat 3 and is used to drive the two connecting plates 5 to move closer to each other. The driving assembly 7 includes a driving motor 71 and a double-headed screw 72. The driving motor 71 is fixed on the side wall of the mounting seat 3, and the output shaft of the driving motor 71 passes through the side wall of the mounting seat 3 and is rotatably connected. The double-headed screw 72 is a horizontally arranged rod-shaped structure, the double-headed screw 72 is fixed to the end of the output shaft of the driving motor 71, and the axis of the double-headed screw 72 coincides with the axis of the output shaft of the driving motor 71. One end of the double-headed screw 72 away from the output shaft of the driving motor 71 is rotatably connected to the inner wall of the slide groove 31, and the double-headed screw 72 is provided with two sections of threads with equal pitch and opposite rotation direction, and the two connecting plates 5 are respectively threadedly connected with the two sections of the threads of the double-headed screw 72.

[0031] The knitting machine body 2 is pushed to move by the universal wheel 4, eliminating the laborious operation of carrying the knitting machine body 2. When the knitting machine body 2 needs to be fixed, the staff pushes the knitting machine body 2 between the two clamping blocks 6, and then starts the drive motor 71 to drive the double-headed screw 72 to rotate. Since the two connecting plates 5 are threadedly connected with the two sections of threads on the double-headed screw 72, the two connecting plates 5 are slidingly connected with the inner wall of the slide groove 31, so that the two connecting plates 5 are moved closer to each other, so that the two clamping blocks 6 cooperate and clamp the base 1, which reduces the probability of displacement of the knitting machine body 2 and improves the stability of the knitting machine body 2.

[0032] In order to further reduce the probability of displacement of the base 1 and the large circular knitting machine body 2, anti-skid pads 8 are fixed to the side walls of the two clamping blocks 6 that are close to each other.

A shock-absorbing spring 13 and a damping block 14 are fixed to the bottom wall of the installation groove 101. The upper end of the shock-absorbing spring 13 and the top of the damping block 14 are fixed to the lower surface of the fixing plate 12. The setting of the shock-absorbing spring 13 and the damping block 14 reduces the vibration generated by the large circular knitting machine body 2, improves the shock-absorbing effect on the large circular knitting machine body 2, and reduces the probability of the position of the large circular knitting machine body 2 being offset due to vibration when working.

[0037] The use principle of a fixed structure for a large circular knitting machine in the present embodiment is: the large circular knitting machine body 2 is pushed to move by the universal wheel 4, thereby eliminating the laborious operation of carrying the large circular knitting machine body 2.
