In this embodiment, the movable lock structure includes a groove disposed on the sidewall of the through slot 231 and an iron connecting member disposed at the diameter adjusting end and capable of being inserted into the groove, and the groove is provided with an electromagnet. Other movable locking structures, such as pins, may of course be provided.

And the lifting member 201 may be an oil cylinder or an air cylinder. The mounting bracket 200 is provided with an annular through hole for the shaft sleeve 220 to pass through, and the shaft sleeve 220 passes through the annular through hole and is connected with the rotary driving member 202 arranged at one side of the mounting bracket 200 far away from the base 100.

When the wood cutting device is used, firstly, the lifting piece 201 drives the positioning shaft 210 to move downwards until the positioning shaft 210 contacts a wood board, and the positioning shaft 210 is fixed at the position, so that the wood is prevented from shifting in the subsequent cutting process to influence the cutting effect. Then, the electromagnet of the groove is not electrified, so that the diameter adjusting end can freely slide in the through groove 231; the shaft sleeve 220 is controlled by the telescopic part to move in the vertical direction along the positioning shaft 210, and the control end of the cutting part 240 rotates to drive the diameter adjusting end to horizontally move in the through groove 231 until the distance from the cutting knife 241 to the positioning shaft 210 is the circular or arc radius required to be cut by wood. Then, the electromagnet of the groove is electrified, the diameter-adjusting end is fixed at the adjusted position through the magnetic attraction effect, the deviation of the diameter-adjusting end in the subsequent cutting process is prevented, and the diameter-adjusting end can drive the guide circular plate 230 to rotate together. Finally, the shaft sleeve 220, the cutting member 240 and the guide circular plate 230 are driven to rotate and move downwards around the positioning shaft 210 by rotating the driving member 202, so that the circular arc wood with the required size is obtained.

In order to solve the supporting problem of the guide circular plate 230, a portion of the positioning shaft 210 close to the base 100 may be provided with a male screw, and the guide circular plate 230 may be provided with a female screw screwed with the male screw. Under the effect of the threaded connection, when the guide circular plate 230 is not rotated, the guide circular plate can be slightly fixed on the positioning shaft 210; when rotated, the pilot circular plate 230 may be rotated to move downward.

Of course, a cylindrical protective shell 250 may be further provided, and the pilot circular plate 230 is screwed to the inner wall of the protective shell 250. The protective housing 250 provides a supporting function for the pilot circular plate 230, and a gap may be left between the pilot circular plate 230 and the positioning shaft 210 to reduce friction between the pilot circular plate 230 and the positioning shaft 210 during rotation.

Meanwhile, the protective case 250 is connected with the mounting bracket 200 through the lifter 201 to further provide a positioning effect.

In addition, in order to prevent the positioning shaft 210 from damaging the wood board, the end of the positioning shaft 210 close to the base 100 and the end of the protective shell 250 close to the base 100 are both provided with a buffer structure, the buffer structure comprises a guide pillar 211 and a through hole arranged on the positioning shaft 210, one end of the guide pillar 211 is inserted into the through hole, and the other end of the guide pillar 211 is connected with a buffer block 212; the guide post 211 is sleeved with a spring 213, one end of the spring 213 is connected with the end of the positioning shaft 210, and the other end is connected with the buffer block 212. Meanwhile, since the surface of the wood may not be uniform and the length thereof is not constant, the buffer structure may effectively position the wood having a non-uniform thickness according to the difference of the compression degree of the spring 213 thereof.

The wood cutting device further comprises a multi-piece cutting assembly, wherein the multi-piece cutting assembly is arranged on one surface, close to the base 100, of the solid part, which is not provided with the through groove 231, of the guide circular plate 230 through the mounting seat 260, and comprises a plurality of guide rollers 261 and a plurality of cutting wheels 262; the guide circular plate 230 is provided with a sliding groove 232, and an installation seat 260 for installing a cutting wheel 262 is arranged on the sliding groove 232 in a sliding manner; the number of the through grooves 231 is 2 or 4.
