[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1-4The utility model provides a technical solution: a digging device for garden construction, including a supporting assembly 1, a lifting assembly 4, a driving machine 5, a connecting assembly 7 and a spiral drill bit 6. The lifting assembly 4 is installed on the upper side of the supporting assembly 1, and a driving machine 5 is arranged on the right side of the lifting assembly 4. The lower end of the driving machine 5 is connected to the spiral drill bit 6 through the connecting assembly 7. The connecting assembly 7 includes an upper connecting block 71, which is arranged at the lower end of the driving machine 5. A lower connecting block 73 is fixed to the upper end of the spiral drill bit 6. A connecting groove 72 is provided inside the upper connecting block 71. The connecting groove 72 and the connecting block cross section are rectangular. Fixing holes 74 are provided on the connecting groove 72 and the lower connecting block 73. Fixing bolts 75 are installed in the fixing holes 74. The supporting assembly 1 provides a stable supporting platform. Through the precise adjustment of the lifting assembly 4, the depth of the drill bit entering the soil can be controlled to meet different digging requirements. The driving machine 5 provides rotational power for the spiral drill bit 6. The connecting assembly 7 is used to quickly disassemble and install the spiral drill bit 6.

[0021] The support assembly 1 includes a support frame 11, a hand handle 12 is fixed to the upper end of the support frame 11, and moving wheels 2 are installed on both sides of the lower end of the support frame 11. The hand handle 12 and the moving wheels 2 are used to facilitate the movement and control of the digging device, so that the digging device can be easily moved on the ground.

[0022] Four groups of fixing cones 3 are installed at the lower end of the support frame 11. The fixing cones 3 can penetrate deep into the soil and effectively prevent the device from sliding or moving during the digging process by contacting the soil.

[0023] The lifting assembly 4 includes a guide rod 42, which is installed on both sides of the support frame 11. A lifting block 43 is movably installed on the outer side of the guide rod 42. The guide rod 42 provides a track for the lifting block 43 to move, ensuring that the lifting block 43 can move stably and smoothly during the lifting process.

[0024] An engine base 51 is fixed to the front side of the lifting block 43, and the driving machine 5 is installed on the upper end of the engine base 51. The fixed connection between the engine base 51 and the lifting block 43 also ensures that the driving machine 5 can move with the lifting block 43 during the lifting process.

[0025] The upper end of the lifting block 43 is connected to the upper end of the support frame 11 through a lifting spring 44. The lifting spring 44 can effectively absorb and buffer the impact and vibration generated during the lifting process.

[0026] A limiting bracket 111 is fixedly provided on the left side of the support frame 11, and a lifting handle 41 is movably installed on the left side of the support frame 11. The lifting handle 41 can press down the lifting block 43 through the limiting bracket 111. The limiting bracket 111 is fixed on the left side of the support frame 11, and its function is to limit the movable range of the lifting block 43. The movement of the lifting block 43 can be controlled by operating the lifting handle 41.

[0027] As an embodiment of the present utility model: when replacing the drill bit of the digging device for garden construction, first check the state of the connecting assembly 7, the fixing bolt 75 between the upper connecting block 71 and the lower connecting block 73 is in the installed state, and the two are tightly connected together; remove the fixing bolt 75. After the fixing bolt 75 is removed, the connection between the upper connecting block 71 and the lower connecting block 73 will become loose, and then, the lower connecting block 73 fixed with the spiral drill bit 6 is separated from the upper connecting block 71, thereby completing the removal of the spiral drill bit 6; if a new spiral drill bit 6 needs to be installed, the operator only needs to align the lower connecting block 73 on the new spiral drill bit 6 with the connecting groove 72 of the upper connecting block 71, ensure that the cross-section between the two is rectangularly aligned, re-pass the fixing bolt 75 through the fixing hole 74, and tighten it with a tool to ensure that the connection between the upper connecting block 71 and the lower connecting block 73 is firm and reliable, thereby completing the replacement and installation of the spiral drill bit 6.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
