Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-3 This utility model provides an embodiment of a hole-digging device for tree planting, comprising a frame 1, a lifting mechanism 8, and an installation mechanism 9. Handles 10 are fixedly connected to both sides of the frame 1, and casters 12 are installed at the bottom of the frame 1. An installation box 2 is fixedly connected to the top inner side of the frame 1. A forward / reverse motor 7 is installed on the right side of the installation box 2. The lifting mechanism 8 is installed inside the installation box 2. The lifting mechanism 8 includes a first bidirectional screw 805, one end of which is fixedly connected to the output end of the forward / reverse motor 7. A moving block 801 is threadedly connected to the outer wall of the first bidirectional screw 805. A crossbar 804 is movably installed through the upper surface. A first hinge block 802 is fixedly connected to the bottom of the movable block 801. A connecting rod 803 is hinged to the bottom of the first hinge block 802. A second hinge block 806 is hinged to the bottom of the connecting rod 803. A movable plate 807 is fixedly connected to the bottom of the second hinge block 806. A movable rod 808 is fixedly connected to the bottom of the movable plate 807. The lower end of the movable rod 808 passes through the mounting box 2 and is fixedly connected to the top of the transmission plate 3. A transmission plate 3 is provided at the bottom of the mounting box 2. A drive motor 4 is installed at the bottom of the transmission plate 3. A rotating rod 5 is fixedly connected to the output end of the drive motor 4.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, in use, when it is necessary to dig a hole in the ground, the output end of the positive and negative motor 7 can drive the first bidirectional screw 805 to rotate. The rotation of the first bidirectional screw 805 drives the two moving blocks 801 to move in a direction away from each other. The movement of the two moving blocks 801 drives the two first hinge blocks 802 to move. The movement of the two first hinge blocks 802, through the cooperation of the connecting rod 803 and the second hinge block 806, drives the moving plate 807 to move downward. The downward movement of the moving plate 807 drives the transmission plate 3 to move downward through the moving rod 808. The downward movement of the transmission plate 3 ultimately drives the digging rod 11 to move downward. At the same time, the output end of the drive motor 4 can drive the rotating rod 5 to rotate. The rotation of the rotating rod 5 drives the digging rod 11 to rotate, thereby carrying out the digging work.

[0026] The lower surface of the rotating rod 5 is provided with an installation groove 6, and the top of the installation groove 6 is provided with an installation mechanism 9. The installation mechanism 9 includes a fixing groove 907, which is located on the outer wall of the right side of the rotating rod 5. A hexagonal screw head 908 is rotatably provided inside the fixing groove 907. A second bidirectional screw 902 is fixedly connected to the left side of the hexagonal screw head 908 via a transmission rod. A threaded block 901 is threadedly connected to the outer wall of the second bidirectional screw 902. A limit rod 906 is movably provided through the upper surface of the threaded block 901. A transmission block 903 is fixedly connected to the bottom of the threaded block 901. A positioning hole 905 is provided on the side of the two transmission blocks 903 that are close to each other. A positioning rod 904 is movably provided inside the positioning hole 905 and is fixedly connected to the transmission block 903. A digging rod 11 is movably provided inside the installation groove 6.

[0027] Specifically, such as Figure 1 and Figure 3As shown, when it is necessary to disassemble and replace the excavator rod 11, the hexagonal screw head 908 can be rotated using a tool. The rotation of the hexagonal screw head 908 drives the second double-acting screw 902 to rotate via the transmission rod. The rotation of the second double-acting screw 902 drives the two threaded blocks 901 to move in a direction away from each other. The movement of the two threaded blocks 901 drives the two transmission blocks 903 to move. The movement of the two transmission blocks 903 drives the positioning rod 904 to move in a direction away from the positioning hole 905 until the positioning rod 904 disengages from the positioning hole 905. Then, the excavator rod 11 is moved downwards until the upper end of the excavator rod 11 disengages from the mounting groove 6, thus completing the disassembly of the excavator rod 11. When it is necessary to install a new excavator rod 11... When installing the digging rod 11, insert the upper end of the digging rod 11 into the mounting slot 6, and then rotate the hexagonal screw head 908 in the opposite direction using a tool. The rotation of the hexagonal screw head 908 eventually drives the positioning rod 904 into the positioning hole 905, thus completing the installation of the digging rod 11. This facilitates the disassembly, replacement, and installation of the digging rod 11, thereby better meeting the usage needs of different scenarios. It also facilitates the reasonable adjustment of the pit diameter, improving the usage effect. This solves the problem that while the digging rod 11 and the drive motor 4 are an integrated structure, it is not possible to replace different digging rods 11 according to the needs of the usage scenario, which makes it inconvenient to reasonably adjust the pit diameter and results in poor usage effect.

[0028] Working Principle: In this application, when the excavator rod 11 needs to be disassembled and replaced, the hexagonal screw head 908 can be rotated using a tool. The rotation of the hexagonal screw head 908 drives the second double-direction screw 902 to rotate via a transmission rod. The rotation of the second double-direction screw 902 drives two threaded blocks 901 to move in a direction away from each other. The movement of the two threaded blocks 901 drives two transmission blocks 903 to move. The movement of the two transmission blocks 903 drives the positioning rod 904 to move in a direction away from the positioning hole 905 until the positioning rod 904 disengages from the positioning hole 905. Then, the excavator rod 11 is moved downwards until the upper end of the excavator rod 11 disengages from the mounting groove 6, thus completing the disassembly of the excavator rod 11. When a new excavator rod 11 needs to be installed, the upper end of the excavator rod 11 is inserted into the mounting groove 6. Then, the hexagonal screw head 908 is rotated in the opposite direction using a tool. The rotation of the hexagonal screw head 908 ultimately drives the positioning rod 904 to insert into the positioning hole 905, thus completing the installation of the excavator rod 11. The device is designed to facilitate the disassembly, replacement, and installation of the excavator rod 11, thereby better meeting the needs of different scenarios and allowing for reasonable adjustment of the pit diameter, improving its effectiveness. Secondly, when digging a hole in the ground, the output of the forward and reverse motor 7 drives the first bidirectional screw 805 to rotate. The rotation of the first bidirectional screw 805 drives two moving blocks 801 to move in mutually distancing directions. The movement of the two moving blocks 801 drives two first hinge blocks 802 to move. The movement of the two first hinge blocks 802, through the cooperation of the connecting rod 803 and the second hinge block 806, drives the moving plate 807 to move downwards. The downward movement of the moving plate 807 drives the transmission plate 3 to move downwards via the moving rod 808. The downward movement of the transmission plate 3 ultimately drives the excavator rod 11 to move downwards. Simultaneously, the output of the drive motor 4 drives the rotating rod 5 to rotate, which in turn drives the excavator rod 11 to rotate, thus commencing the digging operation.
