The positioning component 44 is arranged at the upper end of the drill bit 3, and the control component 45 is arranged at the lower end of the positioning component 44.
[0024] Adopting the above scheme: By arranging the fixing device 4, when cleaning the drill bit 3, it is convenient to disassemble the drill bit 3 from the body 2 and install it after cleaning, so as to facilitate the cleaning of the drill bit 3 of the hole digger.
[0025] Referring to Figure 2 and Figure 3, the self-locking assembly 43 includes a moving rod 431, a chuck 432 and a push spring 433. The number of moving rods 431 is two, and they are respectively arranged at the upper and lower ends on one side inside the placement groove 41. The left and right ends of the two moving rods 431 are respectively fixedly connected to the inner surface of the placement groove 41 and the fixed block 42. The chuck 432 is sleeved on the front ends of the two moving rods 431 and is slidably connected to the two moving rods 431. The number of push springs 433 is two, and they are respectively sleeved on the surfaces of the two moving rods 431. The front and rear ends of the two push springs 433 are respectively fixedly connected to the rear surface of the chuck 432 and the front surface of the fixed block 42.
[0026] With the above scheme: by setting the self-locking assembly 43 to cooperate with the moving groove 5 at the upper end of the drill bit 3, the drill bit 3 is fixed, which facilitates the installation and fixation after cleaning the drill bit 3.
[0027] Reference Figure 2 、 Figure 3 And Figure 4 , four moving grooves 5 are evenly formed on the inner surface of the upper end of the drill bit 3 in a circumferential direction. The four moving grooves 5 penetrate through the body 2 and the drill bit 3. The positions of the four moving grooves 5 correspond to the positions of the four positioning assemblies 44.
[0028] With the above scheme: by evenly forming four moving grooves 5 on the inner surface of the upper end of the drill bit 3 in a circumferential direction and penetrating through the body 2 and the drill bit 3, it is used to cooperate with the self-locking assembly 43 to fix the drill bit 3.
[0029] Reference Figure 2 And the figure, the positioning assembly 44 includes a bottom plate 441, a positioning rod 442 and a limiting block 443. The bottom plate 441 is sleeved on the upper surface of the upper end of the drill bit 3 below the moving groove 5 and is fixedly connected to the drill bit 3. The number of positioning rods 442 is four, and the lower ends are respectively and evenly fixedly connected to the upper surface of the bottom plate 441 in a circumferential direction. The number of limiting blocks 443 is four, and they are respectively fixedly connected to the tops of the four limiting blocks 443, and one end is fixedly connected to the surface of the drill bit 3.
[0030] With the above scheme: by setting the positioning assembly 44, it is used to position the control assembly 45, avoiding the random rotation of its pull ring 451 and restricting the pull ring 451 to only move up and down.
[0031] Reference Figure 2 、 Figure 3 And Figure 4, the control component 45 includes a pull ring 451, a reset tension spring 452, and a pressing block 453. The pull ring 451 is sleeved on the surfaces of the four positioning rods 442 and the drill bit 3, and is movably connected to the four positioning rods 442 and the drill bit 3. The number of reset tension springs 452 is four, and they are respectively sleeved on the lower surfaces of the four positioning rods 442. The upper and lower ends of the four reset tension springs 452 are respectively fixedly connected to the lower surface of the pull ring 451 and the upper surface of the bottom plate 441. The number of pressing blocks 453 is four, corresponding to the four moving grooves 5, and they are respectively and uniformly fixedly connected to the inner circumferential surface of the pull ring 451.
[0032] Adopting the above solution: By setting the control component 45, it is used to drive and control the self-locking component 43, and has the function of simultaneously extruding and moving the four chucks 432 to release the fixation of the drill bit 3, thereby facilitating the disassembly and cleaning of the drill bit 3.
[0033] Reference Figure 2 and Figure 3 , the positions of the four pressing blocks 453 correspond to the four moving grooves 5, and the mutually approaching ends extend into the interior of the moving grooves 5 and are movably connected to the moving grooves 5.
[0034] Adopting the above solution: By setting the positions of the four pressing blocks 453 to correspond to the positions of the four moving grooves 5 and extending into the interior of the moving grooves 5, when the pull ring 451 is pulled upward, it can drive the pressing blocks 453 to move in the moving grooves 5 and accurately extrude and move the chucks 432.
[0035] The working principle of the present utility model:
[0036] When installing the cleaned drill bit 3, by sleeving the upper end of the chuck 432 on the lower end of the machine body 2 and pushing the drill bit 3 upward, the drill bit 3 will extrude the four chucks 432, and the chucks 432 will be extruded to move on the surface of the moving rod 431 into the placement groove 41, and at the same time, the push spring 433 will be compressed by extrusion. When the drill bit 3 is moved upward to align the moving groove 5 with the chuck 432, the push spring 433 will rebound to push the chuck 432 upward, so that the chuck 432 is inserted into the moving groove 5, thereby completing the installation after cleaning by fixing the drill bit 3. When disassembling and cleaning the drill bit 3, by pulling the pull ring 451 upward on the surface of the positioning rod 442 and stretching the reset tension spring 452 at the same time, when the pull ring 451 moves upward, it drives the four pressing blocks 453 to move upward in the moving groove 5 to extrude the chuck 432, so that the chuck 432 is extruded to move on the surface of the moving rod 431 into the placement groove 41, releasing the fixation of the drill bit 3, and then pulling the drill bit 3 downward to remove it for cleaning.
[0037] In summary, for the gardening soil-digging equipment that is convenient for cleaning, through the combined use of the frame 1, the body 2, the drill bit 3, the fixing device 4, the placement groove 41, the fixing block 42, the self-locking component 43, the moving rod 431, the chuck 432, the push spring 433, the positioning component 44, the bottom plate 441, the positioning rod 442, the limiting block 443, the control component 45, the pull ring 451, the reset pull spring 452, the pressing block 453 and the moving groove 5, it solves the problem of the existing portable hole-digging machine. After the drill bit has been used for a period of time, it needs to be cleaned and maintained. However, the drill bit is usually connected and fixed to the body by bolts. In this way, when cleaning and maintaining the drill bit, tools are still needed to repeatedly tighten the bolts, making it difficult to disassemble and assemble the drill bit, resulting in inconvenient disassembly and assembly work during cleaning and maintenance and affecting work efficiency.
