DETAILED DESCRIPTION
[0024] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0025] like Figure 1-5 As shown, a multifunctional nail remover 100 in one embodiment of the present invention includes a housing 10, a drive assembly 21, a firing pin 22, and a nail removal device 23. The drive assembly 21 is at least partially fixed within the housing 10 and includes a barrel 213 that protrudes from the front side of the housing 10. The firing pin 22 is connected to the drive assembly 21 at one end and extends outside the drive assembly 21 at the other end. The drive assembly 21 drives the firing pin 22 to reciprocate along its own axis within the barrel 213, thereby striking the nail and removing it from the board. The barrel 213 can ensure the movement direction of the firing pin 22 and prevent it from bending or deformation.
[0026] Since the nail remover's target is the nail fixed to the board, when the board is thin, the nail can be directly knocked out. When the board is thick, the nail is subject to greater resistance, and a single hit from the nail remover may push the tip of the nail into the board but fail to completely remove the nail from the board. In this case, a nail lifting device or other tool is needed to lift the nail out. To address this situation, the multifunctional nail remover 100 in this embodiment is provided with a nail lifting device 23, which is connected to the drive assembly 21. The nail lifting device 23 includes a lifting head 232, which can be, for example, a common horn structure, with a V-shaped groove for lifting the nail between the horns. The groove extends outside the housing 10 and is used to lift and pull out the nail when it is impossible to knock out the nail in a single shot. Therefore, when using the multifunctional nail remover 100, there is no need to configure an additional nail lifting device, so that it has the dual functions of hitting and lifting the nail, which improves the functionality of the nail remover and reduces the number of additional tools. The tip 232 is located on the side of the barrel 213 away from the housing 10. Because it is located close to the barrel 213, the operating end of the multi-function nail remover 100 remains unchanged, making it easier to hold and use. Furthermore, the tip 232 is located at one end of the multi-function nail remover 100 in the longitudinal direction. When removing nails, it pushes the other end of the multi-function nail remover 100, extending the lever arm and facilitating nail removal.
[0027] Preferably, the pin-lifting device 23 further includes a rod body 231, a head 232 fixed to one end of the rod body 231, and the other end of the rod body 231 is pivotally connected to the driving assembly 21, so that the pin-lifting device 23 can be rotated and has two states: a working state and a storage state. When in the working state, the rod body 231 rotates to a position parallel to the barrel 213, and the head 232 is away from the housing 10 and close to the output end of the firing pin 22 (such as Figure 1 and when the striker 22 is needed to perform the nail withdrawal action, the nail device 23 can be rotated so that the head 232 is rotated to a position close to the housing 10 (as shown). Figure 2 As shown), at this time, the nail lifting device 23 enters the storage state, and the lifting head 232 is away from the output end of the striker 22, so it will not interfere with its nail withdrawal action.
[0028] In one embodiment, the drive assembly 21 further includes a firing pin bracket 24 mounted to the housing 10. The barrel 213 is secured to the firing pin bracket 24, and the pin-lifting mechanism 23 is pivotally connected to the firing pin bracket 24. Since tool housings are often made of non-metallic materials such as engineering plastics, in this embodiment, the pin-lifting mechanism 23 is not directly attached to the housing 10 but is instead secured to the firing pin bracket 24. This prevents the pin-lifting mechanism 23 from directly acting on the housing 10, potentially causing distortion or even breakage, thereby improving overall stability and service life.
[0029] Preferably, a limiting portion 241 is provided on the striker bracket 24, and the limiting portion 241 is used to determine the position of the pin lifter device 23. When the pin lifter device 23 rotates to the working state, the rod body 231 abuts against the limiting portion 241, and the limiting portion 241 simultaneously prevents the rod body 231 from continuing to rotate toward the striker 24.
[0030] Specifically, the limiting portion 241 is a protrusion protruding from the striker bracket 24. The protrusion is provided with a groove 2411 for accommodating the rod body 231. When the rod body 231 is located in the groove 2411, it is not easy to shake and has higher stability.
[0031] Furthermore, a magnet 25 is fixed in the groove 2411, and the rod body 231 is made of iron material. When the pin-lifting device 23 is in working state, the rod body 231 is adsorbed on the magnet 25. The magnet 25 is used to prevent the pin-lifting device 25 from rotating at will, which affects the use effect.
[0032] like Figure 3 As shown, the housing 10 is further provided with a locking portion 11. The locking portion 11 is composed of, for example, two cylindrical protrusions protruding from the housing 10. The two protrusions are arranged opposite each other, and the gap between them is used to receive and retain the rod 231. The locking portion 11 is used to store the nail lifting device 23 when it is not in use, preventing the nail lifting device 23 from rotating toward the barrel 213 during nail extraction, thereby affecting the normal nail extraction action of the firing pin 22.
[0033] Preferably, a reduced diameter portion 12 is formed on the stop portion 11, which is located at an end of the stop portion 11 away from the housing 10. Figure 3 As shown, the two cylindrical protrusions constituting the locking portion 11 are not completely regular as a whole, and each end of the two protrusions is formed toward each other, and the protrusions constitute the reduced diameter portion 12. The opening distance of the reduced diameter portion 12 is configured to be smaller than the diameter of the rod body 231. Therefore, when the pin device 23 is rotated toward the side of the housing 10, the rod body 231 needs to be squeezed at the reduced diameter portion 12 to be fully engaged with the locking portion 11. In addition, the pin device 23 cannot automatically detach from the locking portion 11 without the aid of external force, thereby further improving the stability of the pin device 23 within the locking portion 11.
[0034] In one embodiment, the tilt head 232 and the rod body 231 are detachably connected and fixed by bolts. Therefore, the tilt head 232 can be replaced with other components to enable the multifunctional nail remover 100 to have other functions and improve flexibility.
[0035] Since the tilt head 232 is fixed to the rod body 231 by bolts, it is easy to imagine that the direction of the tilt head 232 is adjustable, so that the direction of the tilt head 232 can be adjusted when the working environment is complex or the user has a different dominant hand, thereby further improving flexibility.
[0036] The nail remover in the prior art is a pneumatic tool that requires connection to an air source, resulting in poor flexibility and limited scope of use. The multifunctional nail remover 100 in this embodiment is electrically driven. Specifically, a battery 30 is fixed to the bottom of the housing 10, and the drive assembly 21 also includes a motor 212 and a cylinder 211. The firing pin bracket 24 and the cylinder 211 are also fixed to the motor 212. The cylinder 211 is an electric cylinder, and the battery 30 supplies power to the motor 212. The motor 212 drives the piston in the cylinder 211 to move within the cylinder body, converting electrical energy into mechanical energy.
[0037] The battery-driven method frees the multifunctional nail remover 100 from the constraints of gas source and wire, and the overall structure is simpler and more portable.
[0038] In such Figure 1 In the embodiment shown, the nail lifting device 23 and the barrel 213 extend in the same direction, so the operator can directly switch between the firing pin 22 and the nail lifting device 23 without adjusting the orientation of the multifunctional nail remover 100, thereby reducing the operating steps and improving ease of use.
[0039] In one embodiment, the total length of the pin-lifting device 23 is greater than the total length of the barrel 213. Therefore, when the pin-lifting device 23 is used, the pin-lifting head 232 can be rotated to the outside of the output end of the firing pin 22 to avoid interference from the firing pin 22 or the barrel 213 when the pin-lifting device 23 is used.
[0040] Preferably, the nail lifting device 23 is detachably mounted on the striker bracket 24 so that it can be removed and used separately when it is inconvenient to use, thereby further improving flexibility.
[0041] In addition to the functions of removing and lifting nails, the multifunctional nail remover 100 can continuously strike the surface of the board by driving the firing pin 22, and can shake off cement dust and other debris on the surface of the board without the aid of other tools, thereby realizing the recycling and reuse of the board.
[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
[0043] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
