[0002] Forks are made of bamboo, iron, plastic and other materials. After the bamboo fork is made, it needs to be slotted. The bamboo fork needs to be opened with an opening device during processing.

[0003] For example, Chinese patent publication number CN111633760B discloses an opening device, comprising: a base plate, on one side of the top of which are rotatably connected to a plurality of slotting knives at even intervals, and the transmission shafts of the plurality of slotting knives are interconnected; a drive motor, which is installed on one side of the top of the base plate close to the slotting knives, and the output shaft of the drive motor is connected to the transmission shaft of the slotting knives; a fixing device, which is arranged on the base plate; and a pushing device, which is arranged on the base plate.

[0004] Although the above-mentioned opening device achieves the effect of slotting the bamboo fork, the existing opening device still has some defects. Since the sizes of bamboos are different, the bamboos are not stably fixed and pushed to move, which often causes the bamboos to deviate on the travel path, resulting in the bamboos being unable to be accurately cut by the slotting knife, thereby reducing the accuracy of bamboo cutting. In addition, manually pushing the bamboo to move is also more troublesome, and there are also major safety hazards, which reduces the efficiency of bamboo slotting. Utility Model Content
