[0021] The utility model will be further described below with reference to the drawings and embodiments.

[0022] Please refer to Figure 1 - Figure 5, the present utility model provides an embodiment: a device for digging holes before tree planting, including a housing 1, and further including a fixed frame 21 and a hole-digging component. The hole-digging component is arranged inside the housing 1, the outside of the housing 1 is fixedly connected with the fixed frame 21, the inside of the fixed frame 21 is rotatably connected with a support frame 22, the bottom of the support frame 22 is fixedly connected with an insertion block 23, the inner side of the support frame 22 is fixedly connected with a first semi-circular block 24, the inside of the first semi-circular block 24 is rotatably connected with a movable bracket 28, the outside of the housing 1 is slidably connected with a sliding frame 25, the outside of the sliding frame 25 is fixedly connected with a second semi-circular block 27, and the movable bracket 28 is rotatably connected inside the second semi-circular block 27. By sliding the sliding frame 25 outside the housing 1, the support frame 22 is driven by the movable bracket 28 to perform opening and closing activities. By driving the sliding frame 25 to slide downward outside the housing 1, and through the movable bracket 28 rotatably connected inside the second semi-circular block 27 and rotatably connected inside the first semi-circular block 24, the support frame 22 is driven to rotate inside the fixed frame 21 to fix the housing 1. When not in use, by sliding the sliding frame 25 upward, the support frame 22 is stored. The hole-digging component releases the fixation of the sliding disc 31 through the second optical axes 37 on both sides, driving the drill bit 35 to rotate downward to dig a hole. There are three support frames 22, and the three support frames 22 are symmetrically distributed outside the housing 1. The fixed frame 21 is provided with grooves at the corresponding positions of the support frames 22, and the support frames 22 rotate inside the grooves. Through the grooves, the three support frames 22 rotate inside to improve stability.

[0023] Please refer to Figure 2 - Figure 3 , in this embodiment, the outside of the housing 1 is fixedly connected with a limit frame 26. The limit frame 26 is arranged at the bottom of the sliding frame 25. The outside of the sliding frame 25 is fixedly connected with a limit shaft 211. A handle 210 is slidably connected inside the limit shaft 211. A first optical axis 29 is fixedly connected inside the handle 210. The first optical axis 29 is clamped inside the housing 1 and slidably connected inside the sliding frame 25. The outside of the limit shaft 211 is fixedly connected with a fixed disc 212. A first spring 213 is fixedly connected between the fixed disc 212 and the handle 210, making it convenient to store and use the support frame 22, improving the stability of the support for the housing 1, ensuring that the drill bit 35 smoothly digs a hole vertically downward, ensuring the verticality of the hole, and making the planted saplings not easy to fall. The housing 1 is provided with a groove at the corresponding position of the first optical axis 29, and the first optical axis 29 is clamped in the groove. Through the groove, the support frame 22 can be stored and used by clamping, improving convenience.

[0024] Please refer to Figure 4 - Figure 5, in this embodiment, the pit-digging component includes a sliding disc 31 which is slidably connected to the inside of the housing 1. A fixing frame 32 is fixedly connected to the top of the sliding disc 31. A motor 33 is fixedly connected to the inside of the fixing frame 32. The output end of the motor 33 is fixedly connected to a rotating shaft 34 which is rotatably connected to the inside of the sliding disc 31. A drill bit 35 is fixedly connected to the outside of the rotating shaft 34. A handle 36 is fixedly connected to the outside of the sliding disc 31. The handle 36 is slidably connected to the inside of the housing 1. A second optical axis 37 is slidably connected to the inside of the handle 36. The second optical axis 37 is clamped in the inside of the housing 1. A sliding block 38 is fixedly connected to the outside of the second optical axis 37. The sliding block 38 is slidably connected to the inside of the handle 36. A second spring 39 is fixedly connected between the sliding block 38 and the handle 36 to prevent the scattering of sand and soil, facilitate subsequent filling, improve the efficiency of pit-digging, and enhance the practicality. The housing 1 is provided with a groove at the corresponding position of the sliding disc 31, and the sliding disc 31 slides in the groove. The housing 1 is provided with a groove at the corresponding position of the handle 36, and the handle 36 slides in the groove. Through the grooves, the sliding disc 31 is limited to prevent it from shaking and improve stability. The handle 36 is provided with a groove at the corresponding position of the sliding block 38, and the sliding block 38 slides in the groove. Through the groove, the sliding disc 31 is fixed and released by clamping the second optical axis 37 in the groove of the housing 1 for convenient use.

[0025] When working and when the device is needed, by pulling out the handle 210 outward, the handle 210 slides outside the limit shaft 211. The fixed disk 212 is fixedly connected to the outside of the limit shaft 211 to compress the first spring 213, so that it slides through the first optical axis 29 in the corresponding slot of the housing 1, driving the sliding frame 25 to slide downward outside the housing 1. The movable bracket 28 is rotatably connected inside the second semi-circular block 27 and is rotatably connected inside the first semi-circular block 24, driving the support frame 22 to rotate inside the fixed frame 21. When moving to the slot of the housing 1 corresponding to the first optical axis 29, the first spring 213 rebounds by its own elasticity, driving the first optical axis 29 to be clamped in the corresponding slot of the housing 1 to fix the sliding frame 25. The insertion block 23 is inserted into the soil to support the housing 1. When not in use, by pulling out the handle 210 outward, the sliding frame 25 slides upward to store the support frame 22. By starting the motor 33 fixedly connected inside the fixed frame 32, it drives the rotating shaft 34 to rotate inside the sliding disk 31, driving the drill bit 35 to rotate. By pulling out the second optical axis 37 sliding inside the two handles 36 outward, it drives the sliding block 38 to slide inside the handle 36, compressing the second spring 39, so that the second optical axis 37 is away from the corresponding slot of the housing 1, releasing the fixation of the sliding disk 31. By sliding the handle 36 inside the housing 1, it drives the drill bit 35 to rotate downward to dig a hole. After finishing digging the hole, by pulling out the second optical axes 37 on both sides outward to compress the second spring 39, when moving the sliding disk 31 to the slot corresponding to the second optical axis 37, the second spring 39 rebounds by its own elasticity to reset the sliding block 38, driving the second optical axis 37 to be clamped inside the housing 1.

[0026] Through the above steps, the sliding frame 25 drives the movable bracket 28 to open and store the support frame 22, ensuring that the drill bit 35 digs holes smoothly and vertically downward, and ensuring the verticality of the hole, so as to solve the problem that when inserting on uneven ground only through the base, the device cannot be stably supported, resulting in the inclination of the hole.
