Description

[Technical Field]

[0001] The present invention relates to the field of power tools, and particularly to a nail hammering attachment and an impact tool. [Background Art]

[0002] When hanging objects on a wall or doing house decoration, nails need to be driven into workpieces. Currently, there are two common ways to drive nails. One is to use a traditional hammer to knock the nail into the workpiece, but this method is time-consuming and laborious. When the nail reaches the limit position, the hammer is likely to damage the workpiece. The other is to use a power tool to impact the nail into the workpiece, which is time-saving and labor-saving.

[0003] As disclosed in Chinese Patent Publication No. CN102069478B, an electric hammer includes a transmission assembly, an impact assembly, and a clamping mechanism. The clamping mechanism includes a clamping member and driving steel balls to fix the nail in a V-shaped groove. Since the gap at the fixed end of the V-shaped groove is relatively large, only larger nails can be clamped, and small nails cannot be firmly and effectively clamped. At the same time, due to the relatively large head of the clamping mechanism of the electric hammer, it cannot perform wall-adjacent operations at the corner, and the construction versatility is poor. In addition, when the nail reaches the limit position, the operator needs to manually control to stop hammering, and the electric hammer is likely to damage the workpiece, and the user needs to purchase the power tool separately, resulting in a high cost.

[0004] In view of this, it is necessary to design a nail hammering attachment and an impact tool to overcome the defects of the prior art. [Summary of the Invention]

[0005] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a nail hammering attachment and an impact tool with strong versatility and low cost, and its specific technical solutions are as follows:

[0006] A nail hammering attachment is used to assist an impact tool in driving a nail into a workpiece. The nail hammering attachment includes an output rod, a limiting assembly, and a clamping assembly. The limiting assembly is sleeved on one end of the output rod in a relatively sliding manner. The clamping assembly is pivotally connected to the limiting assembly. When the impact tool works, the limiting assembly abuts against the surface of the workpiece, and the other end of the output rod is received in the impact tool. The clamping assembly clamps the shaft portion of the nail in the front-rear direction. One end of the nail faces the output rod, and the other end faces the workpiece. The impact tool drives the output rod to impact the nail.

[0007] A further improved solution is that the limiting assembly includes a limiting shield. The limiting shield is provided with a through hole penetrating in the front-rear direction, and the front end of the output rod passes through the through hole. At least a pair of abutting portions distributed left and right and extending forward are provided at the front end of the limiting shield, and the front end surface of the abutting portion abuts against the surface of the workpiece.

[0008] A further improvement solution is as follows: The clamping assembly includes a support claw, an elastic member, and a pin shaft located between a pair of the abutting portions. A rotary base for fixing the pin shaft is provided on the limit shield. One end of the support claw is sleeved on the pin shaft, and the elastic member is sleeved on the pin shaft and pre-presses the other end of the support claw toward the axis direction of the limit shield.

[0009] A further improvement solution is as follows: At least one protrusion is provided on the surface of the through hole, and at least one guiding groove matching the protrusion is provided on the output rod.

[0010] A further improvement solution is as follows: The rotary base includes a mounting portion and an ear plate. At least part of the pin shaft is received in the mounting portion, and the ear plate is adjacent to the mounting portion. When the elastic member presses the support claw to the limit position, the support claw abuts against the ear plate.

[0011] A further improvement solution is as follows: The other end of the support claw clamps the nail. The nail is coaxial with the output rod, and the end of the nail head is opposite to the front end face of the output rod.

[0012] A further improvement solution is as follows: A straight groove recessed from the surface is provided at the other end of the support claw, and a magnet is fixed in the straight groove. The nail is clamped by the two side walls recessed in the straight groove and the magnet together.

[0013] A further improvement solution is as follows: The output rod includes a front end rod slidably connected to the limit assembly, a rear end rod connected to the impact tool, and a connecting plate connecting the front end rod and the rear end rod in a Z shape.

[0014] A further improvement solution is as follows: The output rod includes a front end rod slidably connected to the limit assembly, a rear end rod connected to the impact tool, and a connecting plate connecting the front end rod and the rear end rod in a straight shape.

[0015] Another solution of the present invention is as follows: An impact tool for driving a nail into a workpiece, the impact tool includes a housing, a motor located in the housing, and an impact assembly; the impact tool further includes the nail hammering attachment described in any one of the above, and the motor drives the impact assembly to impact the output rod, and the output rod impacts the nail.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) A nail hammering attachment provided by the present invention is connected to an impact tool. By applying an impact force to the nail hammering attachment through the impact tool, a nail can be driven into a workpiece. Compared with an electric hammer for nail driving, the electric hammer is a complete machine and needs to be purchased separately by users, with a relatively high cost. However, the nail hammering attachment can be adapted to electric tools with impact functions and has strong versatility.

[0018] (2) A nail hammering attachment provided by the present invention, its clamping assembly includes a support claw, an elastic member and a pin shaft located between a pair of abutting portions. The other end of the support claw is provided with a straight groove recessed from the surface, and a magnet is fixed in the straight groove. The two concave side walls of the straight groove and the magnet jointly clamp the nail. In a traditional electric hammer, the V-shaped groove is relatively large and cannot clamp small nails. In the present invention, the accommodation space of the clamping assembly of the nail hammering attachment is more compact, and the clamping of small nails is more firm and reliable.

[0019] (3) A nail hammering attachment provided by the present invention, its output rod includes a front rod slidably connected to a limiting assembly, a rear rod connected to the impact tool, and a connecting plate that connects the front rod and the rear rod in a Z shape; when performing corner operations, the limiting shield directly abuts against the corner, making up for the height difference between the nail hammering attachment and the top of the electric tool housing, and increasing the applicable operating area of the nail hammering attachment.

[0061] The terms used in the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. For example, the terms indicating orientation or positional relationship such as "upper", "lower", "front", "rear", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the technical features referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0062] Please refer to Figures 1 - 3A nail hammering attachment 20 as shown is installed on an impact tool. In this embodiment, the impact tool presents a hammer drill 10. Of course, the nail hammering attachment 20 can also be connected to other power tools with impact functions. The hammer drill 10 includes a main body housing 100, a motor 110 disposed within the main body housing 100, and a transmission mechanism 300 that transmits the power of the motor 110 to the working head. The transmission mechanism 300 includes a transmission assembly 320, and the transmission assembly 320 includes a gear assembly 321 and an impact assembly 322. The gear assembly 321 is used to transmit the power of the motor 110 to the impact assembly 322, and the impact assembly 322 is used to intermittently strike the working head portion.

[0063] In this embodiment, the gear assembly 321 includes a transmission gear 3211 driven by the motor 110 to rotate and a swing rod bearing 3212 in transmission connection with the transmission gear 3211. The impact assembly 322 includes a cylinder 3221, a piston 3222 slidably fitted within the cylinder 3221, a ram 3223 disposed within the cylinder 3221 and driven by the piston 3222 to reciprocate, and a striker 3224 disposed within the cylinder 3221 to withstand the impact of the ram 3223. The swing rod bearing 3212 drives the piston 3222 to reciprocate, the piston 3222 drives the ram 3223 to reciprocate and intermittently impacts the striker 3224, and one end of the striker 3224 away from the ram 3223 intermittently impacts the working head, realizing the reciprocating motion of the working head and thus realizing the hammering action.

[0064] Please refer to Figure 2 , the nail hammering attachment 20 includes an output rod 210, a limiting assembly 220, and a clamping assembly 230. A plurality of transverse grooves 211 are provided at the rear end of the output rod 210, and the transverse grooves 211 are configured to fit the nail hammering attachment 20 onto the hammer drill 10. A chuck assembly 323 is installed at the front end of the hammer drill cylinder 3221, including a chuck sleeve 3231, a blind hole 3232 formed on the chuck sleeve 3231, and a ball 3233 received in the blind hole 3232. One end of the output rod 210 having the transverse grooves 211 is inserted into the chuck sleeve 3231, and the ball 3233 partially falls into the transverse grooves 211 through the blind hole 3232, thereby defining the longitudinal position of the output rod 210 on the hammer drill 10 of the impact tool.

[0065] Please refer to Figure 3 , Figure 4 and Figure 10, the limiting component 220 includes a limiting shield 221. The top surface 2211 of the limiting shield 221 is set as a horizontal plane. When the nail hammering accessory 20 needs to operate at a corner, the top surface 2211 can better fit with the upper wall surface and be stably positioned with the workpiece; the limiting shield 221 is provided with at least a pair of abutting portions 2212 that are distributed left and right and extend forward. In this embodiment, the abutting portions 2212 are set as a pair distributed left and right. The front end surface 2213 of the abutting portion 2212 is a smooth plane, and it can also be a corrugated surface or a serrated surface to increase the friction with the workpiece, thereby improving the stability of nail driving. The front end surface 2213 abuts against the surface of the workpiece 40.

[0066] Please refer to Figures 3 - 6 , the clamping component 230 includes support claws 231, an elastic member 232, and a pin shaft 2217 located between a pair of the abutting portions 2212. A rotary base 2214 for fixing the pin shaft 2217 is provided on the limiting shield 221. The rotary base 2214 includes a mounting portion 2215 and an ear plate 2218. The mounting portion 2215 has a through pin hole 2216 in the left-right direction. The pin shaft 2217 is installed in the pin hole 2216. One end of the support claw 231 is sleeved on the pin shaft 2217, and the elastic member 232 is sleeved on the pin shaft 2216 and pre-presses the upper end of the support claw 231 toward the axis direction of the limiting shield 221.

[0067] Please refer to Figures 4 - 6 , the ear plate 2218 is provided above the mounting portion 2215 and bends forward. The ear plate 2218 is perpendicular to and integrally formed with the mounting portion 2215; at least one convex block 2311 is provided on both left and right sides of the support claw 231. In this embodiment, one convex block 2311 is provided on one side of the support claw 231. The upper surface of the convex block 2311 abuts against the lower surface of the ear plate 2218 to prevent the support claw 231 from pivoting excessively to limit its pivoting angle. After the ear plate 2218 and the convex block 2311 abut, the top end surface of the support claw 231 is in a horizontal plane, and this position is the limit position where the support claw 231 can pivot.

[0068] Please refer to Figure 5 , Figure 7 , a straight groove 2312 in the front-rear direction is formed in the middle of the support claw 231. A magnet 2313 is provided in the straight groove 2312. The position of the magnet 2313 is lower than the upper surface of the support claw 231, ensuring that the nail 50 can be partially stuck in the straight groove 2312 to limit the left-right movement of the nail 50. At the same time, the magnet 2313 can also attract the nail 50 to limit the up-down movement of the nail 50. By restricting the degrees of freedom of the nail 50, the clamping is firm and reliable.

[0069] Please refer to Figure 3 , Figure 7 and Figure 8, the limiting shield 221 is penetrated through front and back by a through hole 2219, the output rod 210 passes through the through hole 2219, and the through hole 2219 and the output rod 210 are in clearance fit to prevent the output rod 210 from shaking in the through hole 2219. At least one protrusion 2220 is provided on the surface of the through hole 2219. In this embodiment, four protrusions 2220 are provided on the surface of the through hole 2219, and the protrusions 2220 are evenly distributed at 90° in the circumferential direction, and the protrusions 2220 are located at a position closer to the front of the through hole 2219; the output rod 210 is provided with four guiding grooves 2221 distributed at 90° in the circumferential direction and matching with the protrusions 2220. The limiting shield 221 can slide back and forth on the output rod 210 and limit the circumferential movement of the output rod 210.

[0070] Please refer to Figure 2 , Figure 9 and Figure 10 , the output rod 210 is a "Z"-shaped rod. The "Z"-shaped rod includes a front end rod 2111, a rear end rod 2112 and a connecting plate 2113. The front end face of the connecting plate 2113 is integrally connected to the rear end of the front end rod 2111, and the bottom of the rear end face is integrally connected to the front end of the rear end rod 2112. The front end rod 2111 and the rear end rod 2112 are parallel to each other and coplanar but not coaxial. The limiting shield 221 is slidably connected to the front end rod 2111 through the through hole 2219, and the rear end rod 2112 cooperates with the impact tool electric hammer 10.

[0071] Please continue to refer to Figure 2 , Figure 9 and Figure 10 , a triangular plate 2114 is integrally connected between the top of the rear end face of the connecting plate 2113 and the front end of the rear end rod 2112. The triangular plate 2114 is a reinforcing rib. When the limiting shield 221 abuts against the workpiece 40, the rear end rod 2112 receives the impact of the electric hammer 10. When the front end rod 2111 outputs the impact force, it will also receive a reaction force in the backward direction, and the connecting plate 2113 is prone to deform backward. The triangular plate 2114 can increase the strength of the connecting plate 2113 and prevent the connecting plate from deforming under the influence of the reaction force of the workpiece impact during tool nailing.

[0072] As Figure 2 shown, the output rod 210 is set in a "Z" shape, and the front end rod 2111 is higher than the housing of the electric hammer 10. When working in a corner, the abutment of the main body housing 100 against the wall will prevent the nail 50 from being driven into a position close to the wall. Setting it as a "Z"-shaped rod can effectively overcome this drawback. It only needs the top surface 2211 of the limiting shield 221 connected to the front end rod 2111 to abut against the wall, without considering the influence of the height of the main body housing 100 on nailing, and makes up for the height difference between the limiting shield 221 and the main body housing 100 of the impact tool.

[0073] Please continue to refer to Figure 10, a spring 213 is sleeved on the front rod 2111 of the output rod 210. The front end of the spring 213 abuts against the rear end of the protrusion 2220, and the rear end of the spring 213 abuts against the front surface of the connection plate 2113. Due to the tension of the spring 213, the limit shield 221 is always subjected to a forward elastic force; please refer to Figure 3 As shown, the front end of the output rod 210 includes a shaft groove 217, as well as a gasket 214 and a snap ring 215 sleeved on the shaft groove 217. The outer diameter of the gasket 214 is larger than the through hole 2219, and the snap ring 215 is fastened to the front end of the gasket 214, jointly preventing the limit shield 221 from detaching from the output rod 210 under the action of the tension of the spring 213.

[0074] Please refer to Figure 6 and Figure 10 , as Figure 10 shown, for the initial state where the electric hammer 10 is assembled with the nail hammering attachment 20 and holds the nail 50, under the action of the spring tension, the limit shield 221 extends to the maximum stroke through the limitation of the gasket 214 and the snap ring 215. The support claw 231, under the action of the protrusion 2220 and the ear plate 2218, keeps the top surface of the support claw 231 in a horizontal plane. The nail 50 is stuck in the straight groove 2312 of the support claw 231 and is firmly held by the suction force of the magnet 2313. The nail 50 is coaxial with the output rod 210 and the nail head end 510 of the nail 50 is opposite to the front end 212 of the output rod.

[0075] Please refer to Figure 2 and Figure 11 , when the electric hammer 10 starts to work, the impact assembly 322 transmits the impact force to the impact rod 3224, and the impact rod 3224 impacts the rear rod 2112 of the output rod 210 clamped in the chuck 323. While receiving the impact force, the output rod 210 overcomes the tension of the spring 213 and moves forward. Before the output rod 210 touches the support claw 231, the support claw 231 always plays a role in lifting and straightening the nail 50. As the nail 50 enters the workpiece 40, the front end 212 of the output rod 210 touches the support claw 231. At this time, the nail 50 has entered the workpiece 40 for a certain distance, and the nail no longer needs to be straightened. Moreover, under the action of the thrust of the output rod 210, the support claw 231 overcomes the pre-tightening force of the elastic member 232 and pivots around the pin shaft 2217.

[0076] As Figure 12 shown, the output rod 210 continues to impact forward. When the nail 50 is completely driven into the workpiece 40, the rear end face of the limit shield 221 abuts against the front end face of the connection plate 2113, so that the output rod 210 reaches the maximum impact position due to the connection plate 2113, which can prevent the output rod 210 from continuing to impact the workpiece 40 when the nail 50 is completely driven into the workpiece 40, thus damaging the workpiece 40.

[0077] In the present invention, an impact force is applied to the nail hammering attachment 20 by the impact tool, an electric hammer 10, to drive a nail 50 into a workpiece 40. Compared with an electric hammer for driving nails, which is a complete machine and requires the user to purchase it separately at a relatively high cost, the nail hammering attachment 20 can be adapted to electric tools with an impact function and has strong versatility. The clamping assembly 230 includes a support claw 231 located between a pair of abutting portions 2212, an elastic member 232, and a pin shaft 2217. The other end of the support claw 231 is provided with a straight groove 2312 recessed from the surface, and a magnet 2313 is fixedly provided in the straight groove 2312. The nail 50 is clamped jointly by the two concave side walls of the straight groove 2312 and the magnet 2313. In the V-groove structure of a traditional electric hammer, the gap at the fixed end is relatively large, and the accommodation space of the clamping assembly of the nail hammering attachment is more compact, and the clamping of small nails is more firm and reliable. The output rod 210 includes a front end rod 2111 slidably connected to the limiting assembly 220, a rear end rod 2112 connected to the impact tool, and a connecting plate 2113 that connects the front end rod 2111 and the rear end rod 2112 in a Z shape. When performing corner operations, the limiting guard 221 directly abuts against the corner, compensating for the height difference between the nail hammering attachment 20 and the top of the electric tool housing, and increasing the applicable operation area of the nail hammering attachment 20.

[0078] Please refer to Figure 13 and Figure 14 , which is another embodiment of the present invention. The output rod 210' is a "one"-shaped rod. The "one"-shaped rod includes a front end rod 2111', a rear end rod 2112', and a connecting plate 2113'. The front end face of the connecting plate 2113' is integrally connected to the rear end of the front end rod 2111', and the bottom of the rear end face is integrally connected to the front end of the rear end rod 2112'. The connecting plate 2113' is provided as an annular plate, and its outer diameter is larger than the outer diameters of the front end rod 2111' and the rear end rod 2112'. The connecting plate 2113' can also be provided as a limiting protrusion circumferentially distributed along the front end rod 2111' or the rear end rod 2112'. The front end rod 2111' and the rear end rod 2112' are coaxial. The limiting guard 221 is slidably connected to the front end rod 2111' through a through hole 2219. The rear end of the spring 213 abuts against the front end face of the connecting plate 2113', and the rear end rod 2112' cooperates with the impact tool.

[0079] The present invention is not limited to the above specific embodiments. It can be easily understood by those of ordinary skill in the art that, without departing from the principles and scope of the present invention, there are many alternative solutions to the present invention. The protection scope of the present invention shall be subject to the content of the claims.
