[0002] Cork tenoning is a traditional woodworking technique, mainly used in furniture making or decoration fixing scenarios to enhance the stability and firmness of the connection between wood parts. This technique involves grooving (mortise) one end of the wood, making a matching protrusion (tenon) at the other end, and then tightly assembling the two together; the cork is used to further reinforce this connection point to prevent the tenon from loosening.

[0003] Cork tenoning is to process the cork into the required shape and size to ensure that it can be inserted into the connection point for reinforcement. The existing cork processing method is to cut it into the required shape by using a cutting knife. However, it is very difficult to quickly cut out the cork of the required size by manual cutting, and it is necessary to frequently insert the cut cork to test whether it is suitable. Therefore, the processing method has low efficiency. Content of the Utility Model

[0021] It is easy to understand that according to the technical solution of the present utility model, without changing the essential spirit of the present utility model, those of ordinary skill in the art can propose various structural forms and implementation methods that can be mutually replaced. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present utility model, and should not be regarded as the whole of the present utility model or as a limitation or restriction on the technical solution of the present utility model.

[0022] A cutter head for wooden plug tenoning, as Figure 1 , Figure 2 shown, includes an outer cover 2. The outer cover 2 adopts a frustum structure with one end thick and one end thin. A jack 21 is provided on the side surface of the outer cover 2, and a blade 3 is inserted into the jack 21. A chute 31 is provided on the surface of the blade 3, and the chute 31 is cooperatively connected with a locking assembly 4. The locking assembly 4 includes a gasket 41, a nut 42 and a screw 43. The screw 43 is fixed on the side wall of the jack 21, and the screw 43 penetrates through the chute 31. The screw 43 is at different positions in the chute 31 to change the processing depth of the blade 3. The screw 43 is threadedly connected with the nut 42, and a gasket 41 is provided on the side of the nut 42. The nut 42 cooperates with the gasket 41 to fix the blade 3 on the side of the jack 21.

[0023] When processing wooden plugs, the sizes of wooden plugs used in different places are different. In order to change the size of the wooden plugs, by adjusting the depth of insertion of the blade 3 into the outer cover 2, the size of the processed wooden plugs can be changed. When adjusting, the nut 42 needs to be rotated, and then the blade 3 is moved so that the blade 3 moves in the jack 21. When the blade 3 moves, the screw 43 moves in the chute 31 to change the position of the screw 43 in the chute 31. After reaching the appropriate position, the nut 42 is rotated to lock and fix the blade 3 to prevent the blade 3 from moving. Then, the adjusted cutter head can be used for processing wooden plugs, and countless wooden plugs can be processed after one adjustment.

[0024] The cutter head for wooden plug tenoning of the present utility model uses the outer cover 2 with a special structure and the inserted blade 3 to complete the processing of wooden plugs when rotating, with a simple structure. At the same time, the size of the processed wooden plugs can be changed by adjusting the depth of insertion of the blade 3 into the outer cover 2 according to requirements, and the scope of use is wide.

[0025] A frustum-shaped processing cavity 22 is provided in the outer cover 2. A connecting rod 1 is fixed to the thin end face of the outer cover 2. The connecting rod 1 is used to connect with an external rotary driving member to drive the whole cutter head to rotate for processing wooden plugs. A through hole communicating with the processing cavity 22 is provided on the thick end face of the outer cover 2.

[0026] To facilitate the discharge of the processed debris, the cross-section of the end of the blade 3 forms a triangular structure, and there is a gap between the blade 3 and the jack 21, as Figure 3 shown.

[0027] To improve the processing rate, two jacks 21 are provided on the side surface of the outer cover 2, and each jack 21 is connected and cooperated with a blade 3 through a locking assembly 4. The two blades 3 are inclined in the processing cavity 22, and the inclination degree is the same as that inside the processing cavity 22, so as to facilitate the cutting of the required shape of the cork, as Figure 4 shown.

[0028] To improve the stability of the fixing of the blade 3, two sliding grooves 31 are formed on the surface of the blade 3, and each blade 3 is connected and cooperated with two locking assemblies 4.

[0029] When the present utility model is in use, as Figure 5 shown, it is necessary to process the A cork 5 as Figure 5 shown into a B cork 5. Before processing, adjust the positions of the two blades 3 according to the size of the required cork 5. When adjusting, rotate the nut 42, and then move the blade 3 so that the blade 3 moves in the jack 21. When the blade 3 moves, the screw 43 moves in the sliding groove 31, changing the position of the screw 43 in the sliding groove 31. Until it reaches the appropriate position, rotate the nut 42 to lock and fix the blade 3; then connect the connecting rod 1 with the rotary drive assembly, fix one end of the A cork 5, and align the processing cavity 22 of the cutter head with the A cork 5. Start the rotary drive assembly to make the A cork 5 extend into the cutter head. At this time, when the cutter head rotates, the blade 3 can be used to cut the inserted part of the A cork 5 to form a B cork 5, and the processing can be completed.
