Therefore, when cutting the rubber tree, the knife head 200 can be ensured to be stable, and can be adaptively rotated according to the uneven surface of the tree, so as to keep the cutting depth of the blade 230 stable. The shapes of the first connecting shaft 211 and the second connecting shaft 226 are not limited, and preferably adopt cylindrical shapes. The knife arm portion 100 is provided with a first connecting hole 120 and a second connecting hole 130, and the first connecting hole 120 and the second connecting hole 130 are respectively used to match the first connecting shaft 211 and the second connecting shaft 226, so that the two shaft bodies are inserted into the knife arm portion 100, so that the knife head is better fixed;

[0041] See attached Figure 2 and attached Figure 3 As shown, specifically, the second main shaft 220 of the cutter head 200 is used to fix the blade 230, and the blade 230 refers to the rubber tapping blade 230, which is the blade 230 used for tapping rubber trees. In the case of rubber tapping, one end of the second main shaft 220 of the cutter head 200 abuts against the rubber tree, and the rubber tree is tapped by the blade 230 installed on the second main shaft 220.

[0042] See attached Figure 2 and attached Figure 3As shown, specifically, one end where the first main shaft 210 and the second main shaft 220 are connected protrudes in a direction away from the knife arm portion 100, that is, the closed end of the knife head portion 200 protrudes in a direction away from the knife arm portion 100.

The other ends of the first main shaft 210 and the second main shaft 220 are movably connected to both sides of the knife arm portion 100, which can ensure the stability of the knife head portion 200 when cutting rubber trees, reduce the shaking of the knife head, and avoid the up and down deviation of the blade 230.

[0043] See attached Figure 2 and attached Figure 3 As shown, in some embodiments, a mounting groove 221 is provided on the second main shaft 220 , and the mounting groove 221 is used to accommodate and mount the blade 230 .

[0044] See attached Figure 2 As shown, in some embodiments, the second spindle 220 is further provided with a blade pressing block 222 , and the blade pressing block 222 presses the blade 230 into the mounting groove 221 .

[0045] Specifically, a mounting groove 221 is provided on the second spindle 220, and the blade 230 is pressed into the mounting groove 221 by a blade pressing block 222. When the blade 230 is installed in this embodiment, the blade 230 can be removed by only opening the blade pressing block 222 during replacement, which facilitates the replacement and installation of the blade 230, improves efficiency, and saves time.

[0046] See attached Figure 2 As shown, in some embodiments, the second spindle 220 is further provided with an adjusting member 223 , and the adjusting member 223 can adjust the length of the blade 230 extending out of the blade head 200 .

[0047] Specifically, the adjusting member 223 is used to adjust the position of the blade 230 relative to the blade holder, that is, to adjust the length of the blade 230 extending from the blade head 200, and the specific length can be set according to specific circumstances. By setting the adjusting member 223 to adjust the length of the blade 230 extending from the blade head 200, the depth of the rubber tree cut by the blade 230 can be controlled, which is convenient for operation.

[0048] See attached Figure 2 As shown, in some embodiments, one end of the adjusting member 223 abuts against the blade 230, and the other end of the adjusting member 223 is connected to the cutter head 200. Adjusting the adjusting member 223 can push the blade 230 to extend toward the object to be cut to adjust the position of the blade 230 relative to the cutter head 200.

[0049] Optionally, the adjusting member 223 can be set as a screw. When the blade 230 is fastened to the cutter head 200 by the blade pressing block 222, one end of the screw abuts against the blade 230, and the other end of the screw is threadedly connected to the cutter head 200 to adjust the position of the screw relative to the cutter head 200. Specifically, the cutter head 200 is provided with an adjusting groove for the screw to be screwed in, and a threaded hole is provided in a section of the adjusting groove. The threaded hole is used to cooperate with the screw to adjust the position of the screw in the adjusting groove. The adjusting groove is connected to the mounting groove 221 for the blade 230 to be embedded. After the blade 230 is placed in the mounting groove 221, adjusting the screw can push the blade 230 to extend in the direction of the object to be cut, so as to adjust the position of the blade 230 relative to the cutter head 200. After the position is adjusted, the blade 230 is fastened to the cutter head 200 by the blade pressing block 222. The adjustment member 223 is provided to facilitate control of the cutting depth of the blade 230, so that the rubber tree will not be damaged due to excessive cutting, and the cutting will not be too shallow, which is convenient for operation.

[0050] See attached Figure 1 and attached Figure 2 As shown, in some embodiments, the dual-axis tool holder further includes an elastic member 240 , one end of the elastic member 240 is connected to the tool arm portion 100 , the second spindle 220 has a connecting position 224 , and the other end of the elastic member 240 is connected to the connecting position 224 .

[0051] Specifically, an elastic member 240 is connected between the cutter head portion 200 and the cutter arm portion 100, and the second main shaft 220 has a connecting position 224, which is located at the end of the cutter head portion 200 facing away from the blade 230. One end of the elastic member 240 is connected to the connecting position 224, and the other end of the elastic member 240 is connected to the end of the cutter arm portion 100 facing away from the blade 230. Through the provision of the elastic member 240, on the one hand, the cutter head portion 200 is tightened on the surface of the object to be cut, so that the cutter head portion 200 can better perform the rubber tapping action. When tapping rubber, when the cutter head portion 200 moves, the cutter head portion 200 is pressed against the rubber tree under the action of the elastic force of the spring; on the other hand, the elastic member 240 can keep the relative position of the cutter head portion 200 and the cutter arm portion 100 stable. For example, the elastic member 240 can be a tension spring, a thrust spring or a torsion spring. Through the setting of the elastic member 240, when the cutter head 200 moves during rubber tapping, the cutter head 200 is pressed against the rubber tree under the action of the elastic force of the tension spring.

[0052] See attached Figure 1 and attached Figure 4 As shown, in some embodiments, the blade arm portion 100 includes a blade head connector 110, which is used to connect to the first main shaft 210. One end of the blade head connector 110 is detachably connected to the blade arm portion 100, and the other end of the blade head connector 110 is rotatably connected to the first main shaft 210.

[0053] Specifically, the cutter head connector 110 is detachably connected to the cutter arm 100, and can be connected by screw connection, riveting or nut and nut connection. The cutter head connector 110 is provided with a detachable structure. When the cutter head 200 is damaged, the cutter head 200 can be replaced in time without replacing the cutter arm 100, thereby improving the service life of the rubber tapping device. Optionally, the cutter head connector 110 can be a long strip-shaped block, which is used to press the cutter head 200 against the cutter arm 100. One end of the cutter head connector 110 is connected to the cutter arm 100, and the other end of the cutter head connector 110 is provided with a second connection hole 130. Specifically, the process of installing the cutter head portion 200 may be, first, matching the first connecting axis 211 of the cutter head portion 200 with the first connecting hole 120 of the cutter arm portion 100, and then matching the second connecting hole 130 provided on the cutter head connecting member 110 with the second connecting axis 226. After matching, the cutter head connecting member 110 is connected to the cutter arm portion 100, and the cutter head connecting member 110 is fastened to the cutter arm portion 100, thereby pressing the cutter head portion 200 onto the cutter arm portion 100.

[0054] In some embodiments, one end of the tool head connector 110 connected to the first spindle 210 protrudes in a direction away from the installation space.

[0055] See attached Figure 5 As shown, specifically, the cutter head connector 110 includes a first support rod 111 and a second support rod 112, the first support rod 111 is connected to the first main shaft 210, and the second support rod 112 is connected to the cutter arm 100. Optionally, the first support rod 111 and the second support rod 112 can be set in a stepped shape, and the first support rod 111 protrudes in a direction away from the installation space. By protruding the first support rod 111 in a direction away from the installation space, the installation space of the blade 230 is expanded, which is convenient for replacing the blade 230, and the cut bark can be discharged from the installation space in time to avoid blockage and damage to the rubber tapping device.

[0056] See attached Figure 3 As shown, in some embodiments, the second main shaft 220 has a recessed portion 225 on a side close to the object to be cut, and the recessed portion 225 is used to fit the shape of the object to be cut.

[0057] Specifically, the two sides of the recessed portion 225 have a first abutment portion 2251 and a second abutment portion 2252. Because the outer surface of the rubber tree has an inconsistent shape and is uneven, the first abutment portion 2251 and the second abutment portion 2252 can completely abut on the surface of the rubber tree. The shape of the recessed portion 225 can fit the shape of the rubber tree. During the cutting process by the blade 230, the force can be better applied to the blade 230, so that the blade 230 can cut the rubber tree.

[0058] The utility model further provides a rubber tapping device, which includes a double-axis knife holder as in any one of the above embodiments. The rubber tapping device drives the double-axis knife holder to cut the object to be cut through the blade 230.

[0059] Specifically, the rubber tapping mechanism includes a double-axis knife holder. After the rubber tapping mechanism abuts against the rubber tree through the double-axis knife holder, the double-axis knife holder is driven to move relative to the rubber tree, so that the blade 230 cuts the rubber tree, thereby realizing rubber tapping. The double-axis knife holder expands the installation space of the blade 230, which is convenient for replacing the blade 230. The cut bark can be discharged from the installation space in time to avoid blockage and damage to the rubber tapping device.
