DETAILED DESCRIPTION

[0019] The utility model will be further explained in connection with the drawings and examples, but not as the basis for limiting the utility model.

[0020] Example: including bottom plate 1, as shown in the accompanying Figure 1 and the accompanying Figure 2 , bottom plate 1 is assembled with stand 2, and stand 2 is assembled with mounting sleeve 3, and drive rod 4 is movably connected in mounting sleeve 3, and the upper end of drive rod 4 is located outside the mounting sleeve and is fixed with the first reset spring 5 that is attached to the top surface of mounting sleeve 3, for position reset to drive rod; The side of mounting sleeve 3 is integrally formed with transmission shell 6 that is communicated with its inner cavity, and transmission column 7 is rotatably connected in transmission shell 6, and drive gear 8 is fixed to the inner end of transmission column 7; Drive rod 4 is processed with driven tooth 9 that is engaged with drive gear 8, and drive gear rotates and drives driven tooth to realize the movement of drive rod; As shown in the accompanying Figure 3 and the accompanying Figure 4As shown, the lower end of the drive rod 4 is elastically and movably connected to an energy storage block 10. The lower end of the energy storage block 10 is rotatably connected to a drill block 11 via a bearing. The side of the drill block 11 is machined with a spiral groove 12. A movable part 13 is laterally and elastically connected inside the side wall of the mounting sleeve 3. The upper part of the movable part 13 is machined with an unlocking inclined surface 14 corresponding to the lower end face of the drive rod 4. The lower part of the movable part 13 is machined with a locking plane 15 corresponding to the lower end face of the drill block 11 and a reset inclined surface 16 corresponding to the upper end face of the energy storage block 10. The unlocking inclined surface is used to push the movable part inward by the drive rod to unlock it. The locking plane is used to limit the bottom of the drill block to prevent it from moving downward. The reset inclined surface is used to push the movable part inward by the energy storage block. After the drill block passes, it resets. At this time, the movable part weighs... The new outward movement allows the locking plane to re-fit with the drill block, and the distance by which the unlocking ramp protrudes laterally from the inner wall of the mounting sleeve is greater than the distance by which the locking plane protrudes laterally from the inner wall of the mounting sleeve, ensuring that the unlocking ramp can drive the locking plane to fully enter the mounting sleeve wall; the lower part of the mounting sleeve 3 is fixed with a fixing block 17 that matches the spiral groove 12, and a roller that matches the spiral groove can be fitted on the fixing block to reduce friction; the bottom of the drill block 11 is fitted with a drill bit seat 18, and the drill bit 19 is fitted on the drill bit seat 18. The drill bit seat is connected to various specifications of drill bits by means of a chuck, which is a technical means well known and mastered by those skilled in the art, and will not be described in detail here; the end of the drive rod 4 is fixed with an energy storage spring 20 connected to the energy storage block 10. The energy storage spring adopts a high elastic modulus and high response. Materials that enhance speed, such as alloy spring steel, have a higher elastic modulus than ordinary spring steel. Under the same external force, they can undergo elastic deformation and store elastic potential energy more quickly, and can also return to their original shape more rapidly upon release, providing faster impact power for the drill bit. The energy storage block 10 fits into the inner cavity of the mounting sleeve 3, guiding the movement of the energy storage block. A C-shaped movable cavity 21 is machined in the side wall of the mounting sleeve 3. The movable part 13 is C-shaped and is correspondingly adapted and connected to the movable cavity 21. A second return spring 22 connected to the cavity wall of the movable cavity 21 is fixed to the side of the movable part 13 to achieve rapid return of the movable part. The unlocking inclined surface 14 is provided on the top surface of the upper protrusion of the movable part 13. The locking plane 15 is provided on the lower surface of the movable part 13. The top surface of the end protrusion and the reset inclined surface 16 are set on the bottom surface of the lower end protrusion of the movable part 13; the lower end of the spiral groove 12 is provided with a vertical guide groove 23 that is connected to it. The vertical guide groove 23 fits with the fixed block 17 and guides and accelerates the drill block in the initial stage of downward movement; the outer end of the transmission column 7 has a through hole 24 perpendicular to its axis. An L-shaped action rod 25 is installed in the through hole 24 to extend the action arm and save effort; the end of the action rod 25 is machined with a grip handle 26 to improve the comfort of use; the column 2 is equipped with an adjusting fixing sleeve 27. The side of the adjusting fixing sleeve 27 is integrally formed with an extension plate 28. The mounting sleeve 3 is connected to the extension plate 28. The position and height of the mounting sleeve can be flexibly adjusted by adjusting the fixing sleeve, which is suitable for processing various workpieces.The adjusting and fixing sleeve 27 includes a sleeve body 29 connected to the column 2. The sleeve body 29 has an opening 30 extending along its axis on its side. Connecting plates 31 are integrally formed on both sides of the sleeve body 29, and the connecting plates 31 are bolted together. When the bolts are not in use, the opening is not closed, allowing for a clearance fit between the sleeve body and the column, facilitating movement. After the bolts are installed, the opening closes, and the sleeve body exerts pressure on the column, generating friction and achieving fixation. Uniformly distributed rubber blocks 32 are adhered to the inner wall of the sleeve body 29 to further increase friction and improve the fixing effect.

[0021] Working principle: Before use, the heat dissipation substrate to be processed is placed horizontally on the base plate 1. At this time, the bottom surface of the drill block 11 is blocked by the locking plane 15 of the movable part 13, so that the drill block 11 and the drill bit 19 are in a fixed state, ensuring the stability of the device before drilling.

[0022] In use, the operator holds and rotates the handle 26, which drives the L-shaped actuating rod 25 to rotate around the axis of the transmission column 7. The actuating rod 25 then drives the transmission column 7 to rotate, and the driving gear 8 at the inner end of the transmission column 7 rotates together with the transmission column 7. The driving gear 8 meshes with the driven gear 9 on the driving rod 4, thereby driving the driving rod 4 to move downward along the longitudinal direction of the mounting sleeve 3. During the downward movement of the driving rod 4, the energy storage block 10 is blocked by the movable part 13 and cannot move downward. The energy storage spring 20 at the end of the driving rod 4 is compressed, and elastic potential energy gradually accumulates. When the driving rod 4 moves downward to the point where its lower end face contacts the unlocking inclined surface 14 of the movable part 13 and continues to move downward, the driving rod 4 pushes the movable part 13 to overcome the elastic force of the second return spring 22 and move laterally to the outside of the side wall of the mounting sleeve 3. When the movable part 13 moves to a certain extent, it locks. As plane 15 moves away from the lower end face of drill block 11, the energy storage block 10 and drill block 11 lose their lower obstruction, and the elastic potential energy stored in energy storage spring 20 is released instantly, pushing energy storage block 10 to move rapidly downward. Energy storage block 10 drives drill block 11 and drill bit 19 to impact the heat dissipation substrate film at high speed, giving drill bit 19 a greater impact speed, thereby improving the drilling effect. At the same time, during the downward movement of drill block 11, since the fixing block 17 fixed at the lower part of mounting sleeve 3 matches the spiral groove 12 on the side of drill block 11, drill block 11 will also be guided by the spiral groove 12 and the fixing block 17 while moving downward, causing drill block 11 to rotate around its own axis. The rotation of drill block 11 drives drill bit 19 to rotate synchronously. On the basis of high-speed impact, drill bit 19 also has a transverse cutting force generated by rotation, further improving the drilling effect.

[0023] After drilling is completed, the drive rod 4 moves upward and resets under the elastic force of the first reset spring 5. At the same time, the energy storage block 10 pushes the reset inclined surface 16 of the movable part 13, causing the movable part 13 to move laterally to the outside of the side wall of the mounting sleeve 3. After the energy storage block 10 and the drill block 11 move upward past the movable part 13, the movable part 13 quickly moves inward and resets under the elastic force of the second reset spring 22. Its locking plane 15 re-fits with the lower end face of the drill block 11, ready for the next drilling operation.
