The support surface 431 first carries the material before the lifting member 50 lifts. After the lifting member 50 passes through the through hole 4311 on the support surface 431 to extend into the receiving cavity 41, the lifting member 50 lifts the material in a direction away from the support surface 431 so as to clamp the material between the cavity wall of the receiving cavity 41 and the lifting member 50.

[0084] Please also read Figure 3 and Figure 4 In some embodiments, the receiving groove 441 includes a top wall 4411, two first side walls 4412, and a second side wall 4413, and the top wall 4411 and the support surface 431 are arranged opposite to each other along the first direction Z.

The second side wall 4413 is connected between the two first side walls 4412, and the opening 42 is formed between the two first side walls 4412 and the top wall 4411, and the second side wall 4413 and the opening 42 are arranged opposite to each other. The top wall 4411, the two first side walls 4412, and the second side wall 4413 are arranged to form the receiving groove 441, and cooperate with the support surface 431 to reduce the risk of the material escaping from the receiving groove 441.

[0085] Please also read Figure 5 , Figure 6 and Figure 7 In some embodiments, the lifting member 50 includes a lifting drive part 51, a pushing part 52 and a lifting part 53. The lifting drive part 51 is connected to the moving member 30, and the lifting drive part 51 is arranged on the side of the body 43 away from the cover plate 44. The body 43 is provided with a receiving chamber 432, and the pushing part 52 is connected to the transmission end of the lifting drive part 51 and is arranged in the receiving chamber 432. One end of the lifting part 53 is arranged on the side of the pushing part 52 away from the lifting drive part 51, and the other end is configured to slide along the receiving chamber 432 and extend into the receiving chamber 41 through the through hole 4311 to cooperate with the top wall 4411 to clamp the material. The lifting drive part 51 drives the pushing part 52 and the lifting part 53 connected to the pushing part 52 to move in the first direction Z, so as to extend into the receiving chamber 41 through the receiving chamber 432 to clamp the material, or retract back to the receiving chamber 432 to release the material.

[0086] See also Figure 6 In some embodiments, a lifting end 531 is provided at one end of the lifting portion 53 away from the pushing portion 52, and the lifting end 531 is used to push against the material to improve the accuracy of lifting the material. In this embodiment, the lifting end 531 is a pointed structure.

[0087] In this embodiment, the clamping device 100 includes two spaced-apart lifting members 50, and each lifting member 50 includes two spaced-apart lifting portions 53. Accordingly, the support surface 431 is provided with four through holes 4311 communicating with the receiving cavity 432, and the four through holes 4311 are spaced-apart, and each through hole 4311 corresponds to the lifting portion 53 one by one, thereby increasing the number of materials clamped by the clamping device 100.

[0088] Please refer again Figure 5 , Figure 6 and Figure 7 In some embodiments, the lifting member 50 further includes an elastic portion 54. A limiting groove 521 is provided on one side of the pushing portion 52 facing the lifting portion 53. The elastic portion 54 elastically abuts between the groove wall of the limiting groove 521 and the lifting portion 53. The elastic portion 54 is configured to abut the lifting portion 53 in a direction away from the pushing portion 52. The elastic portion 54 provides a buffer when the lifting portion 53 moves toward the accommodating cavity 41 and abuts against the material. At the same time, when clamping the material, the rebound force of the elastic portion 54 acts on the lifting portion 53 to abut against the material.

[0089] Please continue reading Figure 5 , Figure 6 and Figure 7In some embodiments, the lifting member 50 further includes a guide portion 55, which is connected to the side of the pushing portion 52 away from the lifting driving portion 51. The guide portion 55 is provided with a guide hole 551, and the lifting portion 53 passes through and extends out of the guide hole 551.

[0090] Please also read Figure 1 , Figure 2 and Figure 8 The present application also includes a cutting device 200, which includes a cutting device and a clamping device 100 as described above. The support member 40 is also provided with a processing hole 45 connected to the accommodating cavity 41. The cutting device is configured to extend into the accommodating cavity 41 from the processing hole 45 to cut the material after the lifting member 50 abuts against the cavity wall of the accommodating cavity 41 to abut against the material.

[0091] In the above-mentioned cutting device 200, after the lifting member 50 cooperates with the supporting member 40 to clamp the material, the cutting device can cut the material located in the accommodating cavity 41 through the processing hole 45, thereby reducing the risk of material movement during the cutting process and improving the cutting efficiency.

[0092] Please also read Figure 2 and Figure 8 In some embodiments, the diameter of the processing hole 45 can gradually shrink from the support member 40 toward the lifting member 50. The tapered processing hole 45 can reduce the cutting range of the cutting equipment and also guide the cutting equipment, thereby improving the convenience of cutting materials.

[0093] Please refer again Figure 1 , Figure 2 and Figure 8 In some embodiments, the cutting device 200 further includes a blowing member 70, the support member 40 is provided with an air inlet 46 connected to the accommodating chamber 41, and the blowing member 70 is configured to connect to the air inlet 46 and blow out the chips formed by cutting in the accommodating chamber 41. After the cutting device cuts, the blowing member 70 blows out the chips formed by cutting in the accommodating chamber 41, reducing the risk of the chips affecting the next cutting of the material.

[0094] Please continue reading Figure 1 , Figure 2 and Figure 8 In some embodiments, the support member 40 is further provided with an inclined surface 47, which is connected to the opening 42 and is inclined relative to the lifting member 50. The inclined surface 47 is configured to allow the debris blown off by the blowing member 70 to slide out along the inclined surface 47. The blowing member 70 blows the debris in the accommodating cavity 41 to slide out along the inclined surface 47, thereby reducing the risk of the debris directly flying out of the accommodating cavity 41 and making it difficult to collect the debris.

[0095] Please continue reading Figure 1 , Figure 2 and Figure 8 In some embodiments, the cutting device 200 further includes a collecting member 80, which is connected to the base 20 and spaced apart from the rotating drive unit 31. The collecting member 80 is provided with a collecting chamber 81, which is configured to collect debris formed by cutting. Specifically, after the support member 40 cooperates with the jig 10 to clamp the material, the cutting device extends from the processing hole 45 into the accommodating chamber 41 to cut the material to form debris. At this time, the support member 40 is driven by the moving member 30 to rotate to the collecting member 80, and the blowing member 70 blows air into the accommodating chamber 41 through the air inlet 46, so that the debris in the accommodating chamber 41 passes through the opening 42 and slides along the inclined surface 47 into the collecting chamber 81, thereby realizing the function of collecting debris. After blowing the debris in the accommodating chamber 41 into the collecting chamber 81, the moving member 30 drives the support member 40 to rotate toward the jig 10 again to clamp the next material for cutting.
