[0007] Preferably, a notch is evenly provided between the evenly arranged wooden strips of the wooden clamp, and the multiple guide shafts of the metal clamp are all located in the notch.

[0008] Preferably, when the cylinder push rod is pushed out, the multiple wooden planks on the wooden clamp are higher than the guide shaft, and the wooden planks are in effect at this time. When the cylinder push rod is retracted, the height of the wooden planks is lower than the guide shaft, and the guide shaft is in effect at this time.

[0009] Preferably, the guide shaft is cylindrical, with bearings mounted on both ends, and the bearings are installed in a plurality of small holes provided on the guide shaft fixing plate.

[0010] Preferably, the guide shaft is made of aluminum, stainless steel or carbon fiber.

[0011] The beneficial effects of the utility model are as follows: the clamps made of the wooden slats and the guide shaft are switched along with the pushing out and retracting of the cylinder push rod, without stopping the machine, thereby improving production efficiency.
