[0034] The following will be combined with the Figures 1 to 12 The technical solutions of the present invention are clearly and completely described. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] The present invention provides a high-efficiency drilling pick through improvement. Figures 1-12As shown, it includes a base 1, a locking convex ring 2 is provided on the top of the base 1, a mounting cavity 3 is opened inside the locking convex ring 2, and a drill bit 4 that can be quickly disassembled is installed in the mounting cavity 3; a conical upper adjusting ring mechanism 8, a middle adjusting ring mechanism 7 and a lower adjusting ring mechanism 6 are movably installed on the outer wall of the base 1 from top to bottom, and multiple groups of tooth plates 19 are movably installed on the outer walls of the upper adjusting ring mechanism 8, the middle adjusting ring mechanism 7 and the lower adjusting ring mechanism 6, and multiple groups of alloy protrusions 20 are fixed on the outer wall of the tooth plate 19. When the relative positions between the upper adjusting ring mechanism 8, the middle adjusting ring mechanism 7 and the lower adjusting ring mechanism 6 are adjusted, the upper adjusting ring mechanism 8, the middle adjusting ring mechanism 7 and the lower adjusting ring mechanism 6 are adjusted. When the drill bit 4 is in the same position, the position of the alloy protrusion 20 can be freely arranged and combined; multiple groups of locking columns 27 are movably installed in the horizontal direction inside the locking protrusion ring 2, and multiple groups of lifting blocks 38 and extrusion columns 44 are movably installed in the vertical direction inside the locking protrusion ring 2; a threaded sleeve 21 is also threadedly installed on the outer wall of the locking protrusion ring 2, and the bottom of the threaded sleeve 21 limits and locks the upper adjustment ring mechanism 8, and the side inner wall of the threaded sleeve 21 triggers the multiple groups of locking columns 27 structure to fix the outer wall of the drill bit 4, and the top inner wall of the threaded sleeve 21 triggers the multiple groups of lifting blocks 38 and extrusion columns 44 structure to fix the bottom of the drill bit 4 again.

[0036] In this embodiment, the high-efficiency drilling pick consists of three main components: a base 1, a drill bit 4, and an alloy protrusion 20. To use the device, the upper, middle, and lower adjustment ring mechanisms 8, 7, and 6 are sequentially installed on the outer wall of the base 1 from top to bottom. Their relative positions and angles can be freely adjusted according to actual needs, allowing for a flexible arrangement of the tooth plate 19 and the alloy protrusion 20. The locking member 31 is then inserted into the positioning cavity 34. The drill bit 4 is then rotated clockwise. Initial locking of the drill bit 4 is achieved when the horizontal curved plate 32 enters the stop cavity 35. The threaded sleeve 21 is then installed onto the locking protrusion 2. Under the pressure of the threaded sleeve 21, the locking post 27 moves inward along the horizontal locking cavity 25 and, through the insert 30, locks the upper locking groove 24 on the outer wall of the drill bit 4. As the threaded sleeve 21 continues to rotate downward and completes installation, the bottom of the threaded sleeve 21 locks the upper adjustment ring mechanism 8 in place, preventing it from accidentally loosening. When the top inner wall of the threaded sleeve 21 compresses the extrusion column 44, the linkage member 40 slides inward along the bottom of the vertical locking cavity 37, and the lifting block 38 is lifted by the lifting inclined surface 41. The lifting block 38 locks the space between the outer wall of the vertical plate 33 and the inner wall of the positioning cavity 34, thereby re-locking the bottom of the drill bit 4.

[0037] See attached Figure 3 -Attached Figure 6The lower adjusting ring mechanism 6 includes a lower conical ring 9, the middle adjusting ring mechanism 7 includes a middle conical ring 49, and the upper adjusting ring mechanism 8 includes an upper conical ring 50; multiple groups of side tooth cavities 18 that cooperate with the tooth plate 19 are opened on the outer walls of the lower conical ring 9, the middle conical ring 49 and the upper conical ring 50.

[0038] In this embodiment, in order to increase the degree of freedom and reduce the cost of use, multiple sets of independently replaceable tooth plates 19 are designed.

[0039] See attached Figure 2 -Attached Figure 5 A limiting boss 5 for limiting the lower adjusting ring mechanism 6 is fixedly provided on the outer wall of the base 1, a plurality of groups of plug-in columns 10 are fixedly provided on the bottom of the lower conical ring 9, and a plurality of groups of slots 11 cooperating with the plug-in columns 10 are provided on the top of the limiting boss 5; a plurality of groups of plug-in columns 13 are fixedly provided on the bottom of the middle conical ring 49, and a plurality of groups of slots 12 cooperating with the plug-in columns 13 are provided on the top of the lower conical ring 9; a plurality of groups of plug-in columns 3 15 are fixedly provided on the bottom of the upper conical ring 50, and a plurality of groups of slots 3 14 cooperating with the plug-in columns 3 15 are provided on the top of the middle conical ring 49.

[0040] In this embodiment, when the lower conical ring 9 is mounted on the limiting boss 5, a cooperating pin 10 and slot 11 structure are designed to further enhance stability and facilitate quick positioning during installation. When the middle conical ring 49 is mounted on the lower conical ring 9, a cooperating pin 2 13 and slot 2 12 structure are designed to further enhance stability and facilitate quick positioning during installation. When the upper conical ring 50 is mounted on the middle conical ring 49, a cooperating pin 3 15 and slot 3 14 structure are designed to further enhance stability and facilitate quick positioning during installation.

[0041] See attached Figure 2 -Attached Figure 5 Multiple groups of sliders 16 are evenly arranged on the outer wall of the base 1, and multiple groups of sliding grooves 17 cooperating with the sliders 16 are opened on the inner walls of the lower conical ring 9, the middle conical ring 49 and the upper conical ring 50.

[0042] In this embodiment: when the lower conical ring 9, the middle conical ring 49 and the upper conical ring 50 are installed, in order to quickly lock them and freely adjust their relative positions and angles according to actual needs, mutually cooperating sliders 16 and slide grooves 17 are designed.

[0043] See attached Figure 1 and attached Figure 7 The inside of the threaded sleeve 21 is provided with a stepped portion 22 for squeezing the locking convex ring 2 , and the inner side of the threaded sleeve 21 is provided with an inclined portion 23 that fits with the drill bit 4 .

[0044] In this embodiment, a stepped portion 22 is provided to fit and squeeze the outer wall and top of the locking collar 2, thereby further activating the locking post 27 and the squeezing post 44 to double-lock the outer wall and bottom of the drill bit 4. Since the drill bit 4 is tapered, a chamfered portion 23 is provided to further enhance fit and further position the outer wall of the drill bit 4 via the threaded sleeve 21, thereby improving stability during operation.

[0045] See attached Figure 9 , Attachment Figure 11 -Attached Figure 12 The interior of the locking convex ring 2 is provided with multiple groups of horizontal locking cavities 25, and the locking column 27 is movably installed in the horizontal locking cavity 25; symmetrical first reset grooves 26 are provided on both sides of the horizontal locking cavity 25, and a convex plate 28 movably arranged in the first reset groove 26 is fixedly provided on the outer wall of the locking column 27, and a reset spring 29 is connected to the bottom of the convex plate 28; an insert block 30 is fixedly provided on the inner side of the locking column 27, and multiple groups of upper locking grooves 24 cooperating with the insert block 30 are provided on the outer wall of the drill bit 4.

[0046] In this embodiment, when the threaded sleeve 21 is installed, the inner wall of the threaded sleeve 21 presses against the locking post 27. The locking post 27 then moves inward along the horizontal locking cavity 25 and locks the upper locking groove 24 on the outer wall of the drill bit 4 via the insert 30. The movement of the locking post 27 presses against the return spring 1 29. When the threaded sleeve 21 is removed, the return spring 1 29 automatically activates the locking post 27 and insert 30, unlocking the outer wall of the drill bit 4.

[0047] See attached Figure 8 -Attached Figure 10 The bottom of the drill bit 4 is provided with multiple groups of locking members 31, and the locking members 31 include vertical vertical plates 33 and horizontal arc plates 32. The bottom of the installation cavity 3 is provided with multiple groups of positioning cavities 34 for quickly positioning the locking members 31. A stop cavity 35 is also opened on the clockwise inner wall of the positioning cavity 34 for locking the arc plate 32; a lower locking groove 36 is provided at the bottom of the positioning cavity 34, and a lifting block 38 is movably installed in the lower locking groove 36 and locks the vertical plate 33 and the inner wall of the positioning cavity 34. A reset spring 2 39 is also connected to the bottom of the lifting block 38.

[0048] In this embodiment, when quickly installing the drill bit 4, the locking member 31 is first inserted into the positioning cavity 34. At this point, the lifting block 38 remains in place, with its top flush with the bottom of the positioning cavity 34. The drill bit 4 is then rotated clockwise. When the horizontal curved plate 32 is inserted into the stop cavity 35, the initial locking installation is completed. At this point, there is still space between the outer wall of the vertical plate 33 and the inner wall of the positioning cavity 34 for the lifting block 38 to lock.

[0049] See attached Figure 10 -Attached Figure 12 , the locking convex ring 2 is provided with multiple groups of vertical locking cavities 37 connected to the lower locking groove 36 in the vertical direction, and a linkage part 40 is also movably installed at the bottom of the vertical locking cavity 37, and the inner side of the linkage part 40 is provided with a lifting inclined surface 41 for squeezing the lifting block 38; multiple groups of return springs 342 are connected to the outer wall of the linkage part 40, and the outer side of the return spring 342 is connected to the inner wall of the vertical locking cavity 37; the extrusion column 44 is movably installed at the top of the linkage part 40, and the bottom of the extrusion column 44 is provided with an upper extrusion inclined surface 45, and the top of the linkage part 40 is provided with a lower extrusion inclined surface 43 abutting against the upper extrusion inclined surface 45.

[0050] In this embodiment, when the threaded sleeve 21 is installed, the top of the extrusion column 44 protrudes from the locking protrusion 2 in the initial state, so the top inner wall of the threaded sleeve 21 compresses the extrusion column 44. Since the upper extrusion bevel 45 and the lower extrusion bevel 43 remain in contact with each other, the linkage member 40 slides inward along the bottom of the vertical locking cavity 37, and the lifting block 38 is lifted by the lifting bevel 41. When the lifting block 38 moves upward along the lower locking groove 36, it locks the space between the outer wall of the vertical plate 33 and the inner wall of the positioning cavity 34, thereby locking the bottom of the drill bit 4. When the threaded sleeve 21 is disassembled, the linkage member 40 and the lifting block 38 return to their original positions under the action of the return spring 3 42 and the return spring 2 39, and the bottom of the drill bit 4 is unlocked.

[0051] See attached Figure 9 and attached Figure 11 -Attached Figure 12 Symmetrical second reset grooves 46 are provided on both sides of the vertical locking cavity 37, and convex plates 47 movably installed in the second reset grooves 46 are fixedly provided on both sides of the extrusion column 44, and the bottom of the convex plate 47 is connected to a reset spring 48.

[0052] In this embodiment: since the bottom of the extrusion column 44 is only in a fitting relationship with the linkage member 40, in order to further improve the stability during operation, restore it to its original position and avoid accidental falling off of the extrusion column 44, a return spring 48 structure is designed.

[0053] The working principle of the present invention is as follows: When using the device, the upper, middle, and lower adjustment ring mechanisms 8, 7, and 6 are first installed sequentially onto the outer wall of the base 1, from top to bottom. Their relative positions and angles can be freely adjusted according to actual needs, allowing for the arrangement of the toothed plate 19 and alloy protrusions 20 to be freely configured. The locking member 31 is then inserted into the positioning cavity 34. The drill bit 4 is then rotated clockwise. Initial locking of the drill bit 4 is achieved when the horizontal curved plate 32 enters the stop cavity 35. The threaded sleeve 21 is then installed onto the locking protrusion 2. Under the pressure of the threaded sleeve 21, the locking post 27 moves inward along the horizontal locking cavity 25 and, through the insert 30, locks the upper locking groove 24 on the outer wall of the drill bit 4. As the threaded sleeve 21 continues to rotate downward and completes installation, the bottom of the threaded sleeve 21 locks the upper adjustment ring mechanism 8 in place, preventing it from accidentally loosening. When the top inner wall of the threaded sleeve 21 compresses the extrusion column 44, the linkage member 40 slides inward along the bottom of the vertical locking cavity 37, and the lifting block 38 is lifted by the lifting inclined surface 41. The lifting block 38 locks the space between the outer wall of the vertical plate 33 and the inner wall of the positioning cavity 34, thereby re-locking the bottom of the drill bit 4.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
