In this embodiment, the second photoelectric encoding disk 603 is disposed on the left connecting rod 60221 and/or the right connecting rod 60231, and the second photoelectric encoding disk 603 and the second photoelectric sensor 604 interact with each other during the rotation of the connecting rod 60231 to realize the control of the angle transformation of the spacing comb 20 according to the received spacing angle data, so as to ensure the reliability and accuracy of the angle adjustment position of the spacing comb 20; the left arm push rod 60222 and the right arm push rod 60232 are made of metal to ensure the supporting strength.

Preferably, as shown in fig. 1, 2 and 3, the ratio between the extending or retracting length of the spacing comb 20 and the angle between the spacing comb 20 and the blade 10 in the left-right direction is 1:3, which is set to ensure that the spacing comb 20 does not interfere with the blade 10 when rotating to the maximum angle in the left-right direction with respect to the blade 10, for example, the first motor 501 is driven to the adjusting screw 5021 through the first reduction gear box 5, the first photoelectric sensor 5024 detects that the adjusting screw 5021 rotates 1 turn and is set to 1 turn equal to 1mm, the distance of the current position of the position point A, B, C from the start position is 1mm, the second motor 601 is driven to the left connecting rod 60221 and the right connecting rod 60231 through the reversing gear box 6021, the second photoelectric sensor detects that the left connecting rod 60221 and the right connecting rod 60231 rotate 1 turn and is set to 1 turn equal to 604, at the moment, the distance between the current phase of the position point A and the initial position is-1 mm, the distance between the current phase of the position point C and the initial position is +1mm, the angle change of the limiting comb 20 is about 3 degrees when the extending length of the limiting comb 20 changes by 1mm, therefore, the ratio is set to be 1:3, if the angle of the limiting comb 20 needs to be adjusted by 1 degree, the limiting comb 20 only needs to be pushed forward by 0.33mm, and simultaneously, the left support arm push rod 60222 and the right support arm push rod 60232 respectively move by 0.33mm towards opposite directions; the position point A, B, C is located at the left, middle and right positions of the spacing comb 20.
