The end face of the stop bar 5 of the front push guide 4 is a front push stop face, and the end face of the stop bar 5 of the rear pull guide 4 is a rear pull stop face. During push cutting, the front push stop face, the neutral stop face and the depth limiting bottom face are in contact with the cutting face of the tree trunk, and during pull cutting, the rear pull stop face, the neutral stop face and the depth limiting bottom face are in contact with the tree trunk, achieving a three-point positioning effect, making the rubber worker's operation more stable and the rubber tapping depth control more accurate. Regardless of whether it is push cutting or pull cutting, the utility model achieves a three-point positioning effect, making the rubber worker's operation more stable and the rubber tapping depth control more accurate.

[0027] Specifically, the end surface of the connecting rod 6 and the side surface of the blocking rod 5 are cylindrical surfaces, and the bottom of the blocking rod 5 is an arc structure. The surfaces of the front push blocking surface, the rear pull blocking surface and the neutral blocking surface are smooth, which is convenient for operating and controlling the rubber tapping.

[0028] Specifically, the connecting rod 9 is provided with a slider 10, and the handle 1 is provided with a slide groove 11 that cooperates with the slider 10. The sliding direction of the slider 10 and the slide groove 11 is parallel to the baffle rod 7. The slider 10 slides up and down along the slide groove 11 to adjust the height difference between the baffle rod 7 and the blade 2, thereby adjusting the depth of rubber tapping. The slider 10 is provided with a positioning mechanism for limiting the sliding of the slider 10 relative to the slide groove 11. After adjusting the position, the positioning mechanism is used to clamp the slider 10 to fix the position of the connecting rod 5.

[0029] Specifically, the positioning mechanism includes a strip hole 12 provided on the slider 10, through which a bolt 13 passes, and the bolt 13 is threadedly connected to the handle 1. The slider 10 can be tightened on the slide groove 11 by turning the bolt 13, thereby fixing the slider 10. When the position of the slider 10 needs to be adjusted, the bolt 13 is reversed to gradually loosen the slider 10. When the bolt 13 is separated from the slide groove 11, the position of the slider 10 can be adjusted up and down, thereby adjusting the thickness of the rubber skin consumed by tapping.

[0030] Specifically, the driving device 3 includes a motor 14 and a transmission mechanism, and the motor 14 drives the blade 2 to perform a fan-shaped cutting motion through the transmission mechanism. The motor 14 provides power output, and then transmits the power to the blade 2 through the transmission mechanism, driving the blade 2 to perform a fan-shaped cutting motion.

[0031] Specifically, the transmission mechanism includes an eccentric transmission shaft 15, a swing head 16, a rotating shaft 17 and a U-shaped fork 18. The motor 14 drives the eccentric transmission shaft 15 to rotate. The eccentric portion of the eccentric transmission shaft 15 extends into the U-shaped fork 18. The U-shaped fork 18 is connected to the swing head 16. The swing head 16 is arranged on the rotating shaft 17 that is rotatably connected to the handle 1. The blade 2 is fixed on the swing head 16. When the motor 14 rotates, the eccentric transmission shaft 15 is driven to rotate. The eccentric portion of the eccentric transmission shaft 15 extends into the U-shaped fork 18. Therefore, when the eccentric transmission shaft 15 rotates, the U-shaped fork can be driven to swing back and forth. The U-shaped fork 18 is connected to the swing head 16. The swing head 16 is arranged on the rotating shaft 17 that is rotatably connected to the handle 1. The blade 2 is fixed on the swing head 16, thereby driving the blade 2 to swing back and forth to perform a fan-shaped cutting motion.

[0032] Example 2

[0033] Please refer to the attached Figures 1 to 5 The difference between this embodiment and embodiment 1 is that the eccentric transmission shaft 17 is provided with a fan 19. When the eccentric shaft rotates, the fan 19 is driven to rotate, thereby accelerating the air flow, dissipating the heat of the motor 14, and preventing the temperature of the rubber tapping machine from being too high when tapping for a long time.

The first bearing 28 is clamped by the clamping ring 20 to prevent the first bearing 28 from moving up and down on the eccentric transmission shaft 17. The first bearing 28 reduces the friction between the eccentric shaft and the U-shaped fork 18, thereby increasing the service life of the equipment and reducing vibration during use.

[0035] Specifically, the handle 1 is provided with a second bearing 22 and a third bearing 21, the eccentric transmission shaft 17 is connected to the second bearing 22, the second bearing 22 reduces the friction force of the eccentric shaft rotation, the rotating shaft 17 is connected to the third bearing 21, and the third bearing 21 reduces the friction force of the rotating shaft 17 rotation.

[0036] Specifically, the handle 1 includes a handle 23 and a head 24, the handle 23 is connected to the head 24, the drive device 3 is arranged in the head 24, the handle 23 is provided with a detachably connected battery 25, the battery 25 is connected to the electric control board, the speed regulator 27 is installed on the electric control board, and the motor 14 is connected to the electric control board through a control switch 26. The battery 25 is arranged on the handle 23 of the handle 1, and there is no need to carry a power supply and a connecting line separately when performing rubber tapping operations, which is more convenient to use. The control switch 26 is used to control the operation of the motor 14. When the control switch 26 is closed, the motor 14 rotates, and when the control switch 26 is disconnected, the motor 14 stops rotating. The speed regulator 27 is used to adjust the rotation speed of the motor 14, thereby adjusting the speed of rubber tapping, which is convenient for rubber workers to operate.

[0037] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. The protection scope of the utility model should be based on the protection scope of the claims.
