[0027] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] The utility model provides a lunch box printing clamping mechanism. The clamping teeth move outward to expand the arc spring piece outward to adjust the support radius. The inside of the lunch box is clamped on the outside of the arc spring piece. The arc spring piece that expands outward is used to support the inside of the lunch box. It is suitable for printing lunch boxes with different radius. Please refer to Figure 1-Figure 4 , including: a supporting mechanism 100 and a clamping mechanism 200.

[0029] The support mechanism 100 includes a support 110, a hollow shaft 120 and a flange 130. The hollow shaft 120 is disposed on the support 110, and the flange 130 is disposed at the outer end of the hollow shaft 120.

[0030] The support 110 is an L-shaped support, the hollow shaft 120 is connected to the support 110 , and the flange 130 is a hollow structure, the interior of which is connected to the hollow shaft 120 .

[0031] The clamping mechanism 200 is connected to the flange 130, and includes a three-jaw chuck 210, a clamping tooth 220, and an arc-shaped spring piece 230. The three-jaw chuck 210 is fixed on the clamping tooth 220, and the outer ends of the clamping teeth 220 are provided with arc-shaped spring pieces 230;

[0032] The center of the three-jaw chuck 210 is connected to the hollow shaft 120 . The three-jaw chuck 210 is adjusted to make the clamping teeth 220 move synchronously and move radially along the three-jaw chuck 210 , so that the arc-shaped spring piece 230 shrinks or expands.

[0033] Since the inner wall of the lunch box is inclined, it is easy to fall off the arc-shaped spring piece 230. Therefore, a negative pressure mechanism 300 is arranged at the center of the hollow shaft 120. The negative pressure mechanism 300 includes a negative pressure tube 310, a suction cup 320, a screw rod 330, a piston 340 and a rotary handle 350. The negative pressure tube 310 is arranged at the center of the hollow shaft 120 and the three-jaw chuck 210. The suction cup 320 is arranged at the left end of the negative pressure tube 310, the screw rod 330 is arranged at the right end of the negative pressure tube 310, the piston 340 is arranged at one end of the screw rod 330, and the rotary handle 350 is arranged at the other end of the screw rod 330.

[0034] The screw rod 330 is rotated by the rotary handle 350 , and the screw rod 330 drives the piston 340 to move, and the piston 340 extracts the air inside the negative pressure tube 310 .

[0035] Since the support 110 needs to be fixed, the support 110 is provided with evenly distributed mounting holes, the mounting holes including through holes and pin holes, and the support 110 is fixed by connecting bolts and pins using the through holes and the pin holes.

[0036] In order to improve the fixing effect and avoid sliding and falling off, the outer wall of the arc-shaped spring piece 230 is provided with an anti-skid pad 240, and the anti-skid pad 240 is made of rubber pad. The anti-skid pad 240 improves the anti-skid effect and prevents the inner wall of the lunch box from sliding off the arc-shaped spring piece 230.

[0037] Since the hollow shaft 120 can rotate freely on the support 110, in order to facilitate the positioning of the hollow shaft 120, a knob bolt is set at the top of the support 110, and the lower end of the knob bolt contacts the outer wall of the hollow shaft 120, and the knob bolt is used to tighten and position the hollow shaft 120.

[0038] In order to facilitate observation of the position of the piston 340 , the negative pressure tube 310 is a transparent tube, and the position of the piston 340 can be observed through the transparent shell.

[0039] Since the rotary handle 350 needs to be rotated, in order to avoid slipping during operation, the outer wall of the rotary handle 350 is provided with evenly distributed anti-skid ridges to improve the anti-skid effect.

[0040] During specific use, the three-jaw chuck 210 is adjusted to make the locking teeth 220 move synchronously and move radially along the three-jaw chuck 210, so as to change the spacing of the arc-shaped spring pieces 230 so as to make the arc-shaped spring pieces 230 adapt to the inner wall of the circular lunch box, and clamp the inner wall of the lunch box on the arc-shaped spring pieces 230. The lunch box is supported and fixed by the arc-shaped spring pieces 230, and the anti-skid pad 240 is used to improve the anti-skid effect to prevent the inner wall of the lunch box from sliding off the arc-shaped spring pieces 230. The screw rod 330 is rotated by the rotary handle 350, and the screw rod 330 drives the piston 340 to move. The piston 340 extracts the air inside the negative pressure tube 310, so that the suction cup 320 is adsorbed on the bottom of the inner cavity of the lunch box to improve the fixing effect.

[0041] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
