under the action of the first limiting plate 13, the clamping body 11 is further fixed on the wood board, so that the situation that the clamping body 11 is driven to slide on the wood board when the edge trimmer 3 works is avoided, and the length of the opened groove is difficult to limit; in addition, when the clamping body 11 moves to the middle part of the surface to be processed of the wood board, the first limiting plate 13 is not needed, and the first groove 131 can be separated from the fixing bolt 114 by rotating the first limiting plate 13, so that the movement of the clamping body 11 is prevented from being limited; according to the thickness of the part to be processed of the wood board, the L-shaped clamping block 22 is moved in the clamping groove 232, while the L-shaped clamping block 22 moves, the second groove 221 on the L-shaped clamping block 22 moves relative to the connecting bolt 233 until the L-shaped clamping block 22 moves to a proper position, the connecting bolt 233 is screwed down, so that the distance between the L-shaped clamping blocks 22 is larger than the thickness of the part to be processed of the wood board by 0.5-1mm and is fixed, the L-shaped clamping block 22 is in clearance fit with the side surface of the part to be processed of the wood board, the L-shaped clamping block 22 is prevented from shaking in the movement while the L-shaped clamping block 22 does not move along the side surface of the clamping body 11, and the stability of the edge trimmer 3 in grooving of the working part is further ensured; the fixed sleeve 21 is limited by locking the stainless steel hoop 31, so that the length of the part of the working part of the edge trimmer 3 extending out of the round hole 211 is limited, and the fixed base 23 is fixed at the end part of the fixed sleeve 21, so that the length of the part of the working part of the edge trimmer 3 extending out of the first hole 231 on the L-shaped clamping block 22 is limited; therefore, when the downward movement of the L-shaped clamp block 22 is restricted by the clamp body 11, the working portion grooving depth of the edger 3 is also restricted; the problem that the fixed sleeve 21 slides relatively due to vibration when the edge trimmer 3 works is avoided, so that the length of the part of the working part of the edge trimmer 3 extending out of the first hole 231 is changed, the depth of the opened groove is uneven, and the grooving quality is influenced; during operation, after the trimmer 3 is operated to punch a first groove, the second limiting plate 14 is rotated, the end part of the first positioning pin 141 at the end part of the second limiting plate 14 extends into the first groove, then the clamping device 1 is moved until the end part of the first positioning pin 141 hooks the end part of the first groove, and the relative position of the first positioning pin 141 on the clamping device 1 is determined; at the moment, the edge trimmer 3 is started, the first positioning pin 141 is fixed on the clamping device 1, so that the working part of the edge trimmer 3 slides in a reciprocating manner in the area between the limiting blocks 12 and a second groove is formed in the surface to be processed of the wood board, and the distance between the first groove and the second groove is the maximum distance between the first positioning pin 141 and the working part of the edge trimmer 3; because the movement of the working part of the edge trimmer 3 on the clamping device 1 is limited by the clamping bolt 112, the maximum distance between the first positioning pin 141 and the working part of the edge trimmer 3 is a determined fixed value; then moving the clamping device 1 to enable the first positioning pin 141 to hook the end part of the second groove and simultaneously process a third groove, wherein the distance between the second groove and the third groove is also the maximum distance between the first positioning pin 141 and the working part of the edge trimmer 3, and therefore, the processing is repeatedly carried out to enable the edge trimmer 3 to continuously open grooves with equal distances on the surface of the wood board to be processed; the function of the second positioning pin 15 is the same as that of the first positioning pin 141, and when the second positioning pin 15 is used, the second limiting plate 14 is rotated to enable the end part of the second limiting plate 14 to be far away from the edge trimmer 3, so that the second limiting plate 14 is prevented from blocking the movement of the edge trimmer 3; in addition, the first positioning pin 141 can determine the slotting pitch by a multiple of 15 cm, the second positioning pin 15 can determine the slotting pitch by a multiple of 20 cm, and the positioning pins are selected according to actual conditions in slotting to determine the slotting pitch.
