The cutting assembly 30 arranged on the support 10 can move along the length direction of the long strip under the drive structure, and can simultaneously open two incisions on the plastic pipe 50 through the two cutting ends, thereby directly cutting the spline, which can ensure the neatness of the cutting edge of the spline, and can also improve the cutting efficiency, ensure the cutting effect, and has strong practicality.

[0037] In some embodiments, the cutting assembly 30 may be implemented as follows: Figure 2 See the structure shown. Figure 2 The cutting assembly 30 includes a sliding seat 31, a rotating shaft 32, a first driver 33 and a cutting saw blade 34. The sliding seat 31 is slidably arranged on the sliding platform 11 along the first direction, and a hinge seat is arranged on the top of the sliding seat 31. The rotating shaft 32 is arranged along the second direction, and the rotating shaft 32 is rotatably arranged on the hinge seat. The first driver 33 is arranged on the sliding seat 31 and is connected to the rotating shaft 32 by power. Two cutting saw blades 34 are provided, and the two cutting saw blades 34 are coaxially fixed on the rotating shaft 32 and spaced apart along the second direction, and the top of each cutting saw blade 34 is a cutting end.

[0038] The sliding seat 31 can ensure the connection with the rotating shaft 32 and can ensure the movement of the cutting saw blade 34. The two cutting saw blades 34 are arranged at intervals, which can ensure that two incisions are made on the plastic pipe 50 at the same time, and can ensure that the spline is cut and formed at one time, and the first driver 33 can ensure the driving of the two cutting saw blades 34, thereby ensuring the stability of the cutting, and at the same time ensuring that the cutting edge of the spline is neat and the cutting effect is guaranteed.

[0039] In some embodiments, the above-mentioned drive structure can be adopted as follows Figure 2 See the structure shown. Figure 2The driving structure includes a screw rod 41 and a second driver 42. The screw rod 41 is rotatably arranged on the support 10 along the first direction, and is screw-matched with the nut portion arranged at the bottom end of the sliding seat 31. The second driver 42 is fixed on the support 10 and is dynamically connected to the screw rod 41. The second driver 42 drives the screw rod 41 to rotate, thereby ensuring that it drives the sliding seat 31 to move along the first direction, thereby ensuring the cutting of the spline.

[0040] In some embodiments, the support 10 may be configured as follows: Figure 1 See the structure shown. Figure 1 The support 10 is provided with a sliding cavity for placing the nut portion of the sliding seat 31, and the sliding cavity can ensure the placement of the nut portion, thereby ensuring the power connection between the screw rod 41 and the nut portion.

[0041] In some embodiments, the clamping seat 20 may be used as follows: Figure 1 to Figure 2 See the structure shown. Figure 1 to Figure 2 The clamping seat 20 includes a fixed platform 21, a screw rod 22, a clamping plate 23 and a locking nut 24. There are two fixed platforms 21, which are arranged at intervals along the second direction, and the two fixed platforms 21 are both located above the sliding platform 11, and a long strip is formed between the two fixed platforms 21. There are multiple screw rods 22, each of which is arranged along the vertical direction, and each of which is arranged at intervals along the first direction on one of the fixed platforms 21. There are multiple clamping plates 23, each of which is arranged one by one corresponding to each of the screw rods 22, one end of each clamping plate 23 is sleeved on the corresponding screw rod 22, and the other end extends out along the second direction, each of which is located above the fixed platform 21, and each of the clamping plates 23 and each of the fixed platforms 21 enclose a clamping space for fixing the plastic pipe 50. There are multiple locking nuts 24 , each locking nut 24 is arranged in a one-to-one correspondence with each screw rod 22 , and each locking nut 24 is threadedly connected to the corresponding screw rod 22 , and the corresponding clamping plate 23 can be adjusted to fix the plastic pipe 50 between the two fixing platforms 21 .

[0042] Because the plastic pipe 50 is circular, it can be set between the two fixing platforms 21, and then the clamping plate 23 is pressed at the top to form a three-point limit for the plastic pipe 50, which can ensure the stability of the plastic pipe 50. The clamping plate 23 is adjusted by the locking nut 24 to ensure the downward pressure of the clamping plate 23 on the plastic pipe 50, thereby ensuring the stable clamping of the plastic pipe 50. It is easy to operate, easy to disassemble and assemble, and has strong practicality.

[0045] In some embodiments, the fixing platform 21 may be Figure 2 See the structure shown. Figure 2 Each fixing platform 21 is provided with an inclined portion 211 at the end near the long strip mouth. The setting of the inclined portion 211 can ensure that a V-shaped groove is formed above the long strip mouth, which can further ensure the effect of setting up the plastic pipe 50. The two inclined portions 211 can increase the distance between the contact point with the plastic pipe 50 and ensure the stability of the plastic pipe 50. At the same time, it can ensure that the height of the plastic pipe 50 is lowered to ensure contact with the cutting saw blade 34, thereby ensuring the cutting effect, and the practicality is strong.
