[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0023] Reference Figures 1-5 A post hole digger fixing device includes a frame 1, a side plate 2 welded to one side of the frame 1, two connecting blocks 3 welded to one side of the side plate 2, and mounting holes on one side of each connecting block 3. A fixing plate 4 is bolted to the bottom of the frame 1, and a hydraulic cylinder 5 is bolted to the top of the fixing plate 4. One end of the telescopic part of the hydraulic cylinder 5 passes through the fixing plate 4 and is bolted to a connecting plate 6. A connecting frame 7 is bolted to the bottom of the connecting plate 6, and a motor 11 is bolted inside the connecting frame 7. One end of the output shaft of the motor 11 passes through the connecting frame 7 and is fixed to a first rotating shaft 12 via a coupling. The bottom end of the first rotating shaft 12 is connected to a detachable component. The shaft assembly 8 is connected, and the connecting block 3 is installed on the front of the skid steer machine through the mounting hole, thereby fixing the frame 1 on the front of the machine. Then, the hydraulic cylinder 5 is activated to extend, and the hydraulic cylinder 5 pushes the connecting plate 6 to move downward. The connecting plate 6 drives the connecting frame 7 to move downward. The connecting frame 7 drives the first rotating shaft 12 to move downward through the motor 11. The first rotating shaft 12 drives the shaft assembly 8 to move downward and contact the ground. At the same time, the motor 11 is activated, and the motor 11 drives the first rotating shaft 12 to rotate, so that the shaft assembly 8 can dig a hole. This eliminates the need for the operator to hold the machine, avoids the digger from tipping over during the digging process, and improves the safety of the digger.

[0024] In this utility model, the shaft assembly 8 includes a second rotating shaft 14, with a spiral blade 9 welded to the outer side of the second rotating shaft 14. A plug 15 is welded to the top of the second rotating shaft 14, and the bottom of the second rotating shaft 14 is pointed. The detachable assembly includes a fixed cylinder 13, which is welded to the bottom of the first rotating shaft 12. The plug 15 is inserted into the fixed cylinder 13. Two symmetrical clearance holes 18 are opened on both sides of the fixed cylinder 13. Screws 19 are inserted into the two opposing clearance holes 18, passing through the plug 15. A nut is threaded onto the outer side of the screw 19 outside the fixed cylinder 13. The first rotating shaft 12... During rotation, the fixed cylinder 13 drives the insert block 15 to rotate, the insert block 15 drives the second rotating shaft 14 to rotate, and the second rotating shaft 14 drives the spiral blade 9 to rotate. Since the bottom end of the second rotating shaft 14 is pointed, it can dig holes with the help of the spiral blade 9. When different sizes of holes need to be dug, the screw 19 is removed from the fixed cylinder 13, and then the insert block 15 is moved out of the fixed cylinder 13 to disassemble the second rotating shaft 14. Then, the second rotating shaft 14 with different sizes of spiral blades 9 can be replaced. This makes it easy for workers to replace different shaft assemblies 8 for use, improving the convenience of using the hole digger.

[0025] In particular, two sliding grooves 20 are provided on both inner walls of the fixed cylinder 13, and hemispherical locking blocks 17 are slidably connected in each of the sliding grooves 20. Springs 21 are provided in each of the sliding grooves 20, and the two ends of the springs 21 are respectively fixed to the hemispherical locking blocks 17 and the fixed cylinder 13. Two hemispherical slots 16 are symmetrically provided on both sides of the insert block 15, and the hemispherical locking blocks 17 engage with the hemispherical slots 16. When the screw 19 is removed from the fixed cylinder 13, because the hemispherical locking blocks 17 are engaged with the hemispherical slots 16, the shaft assembly 8 will not be affected. The shaft assembly 8 falls downwards under the influence of gravity and needs to be removed manually, which improves the convenience of replacing the shaft assembly 8. At the same time, when the insert block 15 on the second rotating shaft 14 is inserted into the fixed cylinder 13, the insert block 15 can be positioned and installed by the cooperation of the hemispherical locking block 17 and the hemispherical locking groove 16, which makes it easier for the staff to position and install the shaft assembly 8. The bottom of the fixed plate 4 is fixed with two telescopic rods 10 by bolts. One end of the telescopic part of the two telescopic rods 10 is fixed to the connecting plate 6. The telescopic part of the hydraulic cylinder 5 is located between the two telescopic rods 10.

[0026] Working principle: In use, the connecting block 3 is installed on the front of the skid steer machine through the mounting holes, thereby fixing the frame 1 to the front of the machine. Then, the hydraulic cylinder 5 is activated to extend, pushing the connecting plate 6 downward. The connecting plate 6 drives the connecting frame 7 downward. The connecting frame 7 drives the first rotating shaft 12 downward through the motor 11. The first rotating shaft 12 drives the shaft assembly 8 downward to contact the ground. At the same time, the motor 11 is activated, driving the first rotating shaft 12 to rotate. The first rotating shaft 12 drives the insert block 15 to rotate through the fixed cylinder 13. The insert block 15 drives the second rotating shaft 15 to rotate. When shaft 14 rotates, the second shaft 14 drives the spiral blade 9 to rotate, thereby digging a hole. This eliminates the need for manual operation and prevents the hole digger from tipping over during digging, thus improving the safety of the hole digger. When different sizes of holes need to be dug, screw 19 can be removed from the fixed cylinder 13, and then the insert block 15 can be moved out of the fixed cylinder 13 to disassemble the second shaft 14. Then, the second shaft 14 with different sized spiral blades 9 can be replaced. This allows the operator to easily replace different shaft assemblies 8 for use, improving the convenience of using the hole digger.

[0027] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
