Specifically, after the buckle strip cutting mechanism 30 cuts off the buckle strip, the telescopic rod of the first linear motion cylinder 301 is recovered, and the inverted L-shaped frame 310 is driven to ascend through the guide upright column 308 and the lower limiting block 309, and when the inverted L-shaped frame 310 ascends to the final height, a new free end of the buckle strip is lifted upwards, so that the free end of the buckle strip is not lower than the upper surface of the receiving table 306, and the free end of the buckle strip is prevented from being clamped.
The present invention has been described in terms of the above embodiments, and various modifications, arrangements, and connections of the components may be made without departing from the scope of the invention.
