[0045] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0046] See also Figure 1-15 This utility model discloses a nail feeding device 100, which includes a nail pushing mechanism and a nail carrying mechanism.

[0047] The pusher mechanism includes a pusher body 1 and a pusher assembly. The pusher assembly is disposed on the pusher body 1 and includes a pusher elastic element 2 and a pusher block 3. The pusher elastic element 2 and the pusher block 3 abut against each other.

[0048] The nail-carrying mechanism includes a nail-carrying body 5 and a nail-discharging assembly located at one end of the nail-carrying body 5. The nail-pushing body 1 is sleeved outside the nail-carrying body 5, and the nail-pushing body 1 and the nail-carrying body 5 form a nail groove 5a. The nail-pushing block 3 is located inside the nail groove 5a. The nail-pushing body 1 and the nail-carrying body 5 are slidably connected to close or open the nail groove 5a.

[0049] The nail ejection assembly includes a nozzle 6 and a nozzle panel 7. The nail carrier body 5, the nozzle 6, and the nozzle panel 7 are connected in sequence. The nozzle 6 is provided with a nail ejection channel 6a. The nozzle 6 and the nozzle panel 7 form a nail driving channel (not shown in the figure). The nail groove 5a, the nail ejection channel 6a, and the nail driving channel are connected in sequence. The nail pusher block 3 is driven by the nail pusher elastic element 2 to push the nail in the nail groove 6a towards the nail driving channel.

[0050] This utility model's nail feeding device directly forms a nail groove between the nail pusher body and the nail carrier body, eliminating the need for welding. There are no welded positions within the nail groove, allowing the nail to slide freely without jamming or causing the nail to get stuck, thus ensuring stable nail feeding. Furthermore, the manufacturing process is simple and low-cost. This utility model utilizes a nail pusher assembly with a sliding connection between the nail pusher body and the nail carrier body. Pushing the nail pusher body opens the nail groove for easy nailing; it also closes the nail groove. Simultaneously, the elastic force of the nail pusher's elastic element pushes the nail into the nailing channel, achieving automatic nail feeding. Therefore, this utility model is simple and convenient to operate.

[0051] Preferably, such as Figure 2 , 9 As shown, the pusher body 1 is provided with a first guide groove 1a, and the nail carrier body 5 is provided with a guide strip 5b. The guide strip 5b is embedded in the first guide groove 1a, and the pusher body 1 and the nail carrier body 5 are slidably connected by the guide strip 5b and the first guide groove 1a. Preferably, the first guide groove 1a is arranged along the extension direction of the pusher body 1, and the guide strip 5b is arranged along the extension direction of the nail carrier body 5. Therefore, the pusher body can move back and forth along the extension direction of the nail carrier body to open or close the nail slot, which is simple and convenient to operate.

[0052] More preferably, there are two first guide grooves 1a, respectively located on both sides of the bottom of the pusher nail body 1; and there are two guide strips 5b, respectively located on both sides of the bottom of the nail carrier body 5. The first guide grooves 1a and guide strips 5b are compatible.

[0053] like Figure 2 , 7 As shown in Figure 9, the pusher nail body 1 has a second guide groove 1b communicating with the nail groove 5a, and the pusher nail elastic element 2 is disposed within the second guide groove 1b. The pusher nail elastic element 2 is a spring. The second guide groove 1b is arranged along the extending direction of the pusher nail body 1, and the pusher nail elastic element 2 is installed within the second guide groove 1b. Preferably, there are two second guide grooves 1b, respectively disposed on both sides of the pusher nail body 1; and there are two pusher nail elastic elements 2, respectively disposed within the second guide grooves 1b.

[0054] like Figure 8 As shown, the pusher block 3 includes a pusher body 3a and a drive arm 3b connected to each other. The pusher body 3a is disposed within the nail groove 5a, and the drive arm 3b is disposed within the second guide groove 1b, with the drive arm 3b abutting against the pusher elastic member 2. The elastic force of the pusher elastic member is used to push the drive arm to move within the second guide groove, thereby pushing the pusher body to move within the nail groove. The pusher body 3a and the nail groove 5a are compatible in size and shape. The cross-sectional shape of the pusher body 3a is the same as the cross-sectional shape of the nail.

[0055] Preferably, such as Figure 8As shown, one end of the pusher body 1 is provided with an inner limiting member 1d, which extends into the second guide groove 1b. The drive arm 3b can abut against the inner limiting member 1d through the pusher elastic member 2, preventing the pusher block from being pushed out of the pusher body and avoiding separation between the pusher block and the pusher body. The inner limiting member 1d is a cotter pin. The pusher body 3 is provided with a pin hole. By squeezing the inner limiting member, it can be placed in the pin hole. By releasing the inner limiting member, the tension of the inner limiting member will make it lock into the pin hole. The pin hole is connected to the second guide groove, and the inner limiting member extends into the second guide groove.

[0056] It should be noted that when the drive arm abuts against the inner limiting member under the action of the pusher elastic element, the pusher body passes through the nail delivery channel and extends into the nail driving channel. This ensures that all nails in the nail feeding device are pushed into the nail driving channel.

[0057] Furthermore, such as Figure 1-8 As shown in Figures 10-15, the pusher mechanism further includes a slotting assembly 4 located at the other end of the pusher body 1, and the nail carrier mechanism further includes a locking assembly located at the other end of the nail carrier body 5. The slotting assembly and the locking assembly are detachably connected to close or open the nail slot 5a. The slotting assembly 4 and the locking assembly are correspondingly arranged. When the slotting assembly and the locking assembly are connected, the pusher body and the nail carrier body overlap, and the nail slot is closed. When the slotting assembly and the locking assembly are separated, the pusher body can be pulled open, and the nail slot opens. Through the cooperation of the slotting assembly and the locking assembly, the pusher body and the nail carrier body can be fixed together, so that the nail slot is closed and locked, preventing the nail from falling out of the nail slot. In addition, as long as the slotting assembly and the locking assembly are separated, the pusher body can be pulled open to add a nail into the nail slot.

[0058] Preferably, if Figure 3 , 7 As shown in Figure 10, the slotting assembly includes a positioning plate 4a, which is fixedly connected to the push pin body 1; Figure 1-4 As shown in Figures 6, 11, and 15, the locking assembly includes a fixing sleeve 8 fixedly mounted on the nail carrier body 5, a tail buckle 9 mounted on the fixing sleeve 8, and a locking elastic element 10. The locking elastic element 10 abuts against the fixing sleeve 8 and the tail buckle 9, respectively. The tail buckle 9 is detachably connected to the positioning plate 4a via the locking elastic element 10. Specifically, the positioning plate 4a extends upward, so that the top of the positioning plate 4a is higher than the top of the pusher nail body 1. The locking elastic element allows the tail buckle and the positioning plate to be detachably connected, thereby fixing or separating the tail of the pusher nail body and the tail of the nail carrier body to close or open the nail slot. The operation is simple and convenient. The locking elastic element is a torsion spring.

[0059] Better, such as Figure 1-7As shown in Figure 10, the grooving assembly also includes a grooving elastic element 4b, which is mounted on the positioning plate 4a. The tail buckle 9 is engaged with the positioning plate 4a by a locking elastic element 10, so that the grooving elastic element 4b abuts against the nail carrier body 5 and the positioning plate 4a respectively. When the tail buckle is engaged with the positioning plate by the locking elastic element, both ends of the grooving elastic element abut against the nail carrier body and the positioning plate respectively. The nail pusher body overlaps with the nail carrier body, and the nail pusher body is fixed to the nail carrier body under the combined action of the tail buckle, the locking elastic element, and the positioning plate, thus closing the nail groove. When the user presses the tail buckle, the locking elastic element undergoes elastic deformation, separating the tail buckle from the positioning plate. At this time, the grooving elastic element returns to its original shape and interacts with the nail carrier body, causing it to spring open, moving the positioning plate and the nail pusher body. This causes the nail pusher body to move away from the nail carrier body, opening the nail groove. Therefore, the nail groove automatically opens under the action of the grooving elastic element. The grooving elastic element 4b is a torsion spring.

[0060] Better, such as Figure 6 As shown, the nail carrier body 5 has an inclined surface 5c, and the slotted elastic element 4b abuts against the inclined surface 5c and the positioning plate 4a respectively. The inclined surface 5c is inclined outward from the top to the bottom of the nail carrier body 5. One end of the slotted elastic element 4b abuts against the positioning plate 4a, and the other end abuts against the inclined surface 5c. When the positioning plate is not limited by the tail buckle, the slotted elastic element acts on the inclined surface under the action of elastic force, sliding across the inclined surface from the bottom to the top. In this process, the pusher body initially bounces away from the nail carrier body at a very high speed, and gradually the speed slowly decreases until it stops. If the slotted elastic element interacts with the vertical plane, the pusher body will bounce out at a very high speed, which can easily injure the user and cause a large collision force between the pusher body and the nail carrier body, or even cause the pusher body to fly out and completely separate from the nail carrier body. The inclined surface can gradually reduce the reaction force, protecting both the user and the nail feeding device.

[0061] Preferably, if Figure 1-2 As shown in Figure 7, the slotting assembly also includes a positioning seat 4c, which, along with the positioning plate 4a and the pusher nail body 1, are connected in sequence. The positioning seat allows the user to easily hold it to push and pull the pusher nail mechanism, and also serves to reinforce the connection between the positioning plate and the pusher nail body. More preferably, the positioning seat 4c is made of plastic. When the pusher nail body is forcefully pushed against the nail carrier body and the tail clip is engaged with the positioning plate, the positioning seat also acts as a buffer to prevent excessive force.

[0062] Preferably, if Figure 1 , 3As shown in Figure 8, an outer limiting member 1e is provided on the outer side of one end of the pusher body 1. The outer limiting member 1e can be engaged with the fixing sleeve 8 by moving the pusher body 1. The outer limiting member 1e is a bolt. To prevent the pusher body from completely separating from the carrier body, an outer limiting member is provided on the outer side of one end of the pusher body. The outer limiting member and the pusher body are threadedly connected and fixed to the outer side of the pusher body. When the pusher body moves away from the carrier body, the outer limiting member will abut against the fixing sleeve installed on the carrier body, thereby preventing the pusher body from completely detaching from the carrier body.

[0063] Preferably, if Figure 13-14 As shown, the nozzle 6 has a chamfer 6b, which is set along the edge of the entrance of the nail dispensing channel 6a. Since the nozzle and the nail carrier body abut against each other, the nail enters the nail dispensing channel from the nail slot. To avoid unstable nail pushing due to uneven transition or gaps between the nozzle and the nail carrier body, this invention sets a chamfer at the entrance edge of the nail dispensing channel, allowing the nail to enter the nail dispensing channel smoothly without jamming or blocking it.

[0064] Preferably, if Figure 8-9 As shown, the pusher nail body 1 is provided with a viewing hole 1c communicating with the nail groove 5a. Through the viewing hole, the user can see whether there is a nail in the nail groove, thereby determining whether a nail needs to be added. More preferably, the viewing hole 1c is located at the end of the nail carrier body 5 near the nozzle 6.

[0065] Preferably, the nozzle 6 and the nozzle panel 7 are detachably connected. When a nail gets stuck in the nailing channel, the nozzle panel can be loosened to separate the nozzle from the nozzle, allowing the nail to be removed from the nailing channel. This operation is simple and convenient. More preferably, the nozzle panel 7 is provided with a pull hole (not shown in the figure), through which the user's finger can pass to pull the nozzle panel outward, facilitating the removal of the nail.

[0066] Accordingly, see Figure 16 This utility model also discloses a palm fiber pad gun, including a gun body 200 and the aforementioned nail feeding device 100, wherein the gun body 200 and the nail feeding device 100 are connected. Specifically, the gun body 200 and the nail carrier body 5 are fixedly connected. The nailing channel and the nailing port of the gun body 200 are connected. The specific structure of the nail feeding device 100 is as described above and will not be repeated here. The gun body 200 adopts a prior art structure and will not be described in detail here.

[0067] This utility model's nail feeding device directly forms a nail groove between the nail pusher body and the nail carrier body, eliminating the need for welding. There are no welded positions within the nail groove, allowing the nail to slide freely without jamming or causing the nail to get stuck, thus ensuring stable nail feeding. Furthermore, the manufacturing process is simple and low-cost. This utility model utilizes a nail pusher assembly with a sliding connection between the nail pusher body and the nail carrier body. Pushing the nail pusher body opens the nail groove for easy nailing; it also closes the nail groove. Simultaneously, the elastic force of the nail pusher's elastic element pushes the nail into the nailing channel, achieving automatic nail feeding. Therefore, this utility model is simple and convenient to operate.

[0068] When driving a nail, first press the tail latch 9 to pop open the nail pusher body 1 and open the nail groove 5a, then insert the nail into the nail groove 5a. Next, connect the gas tube to the gun body 200, press the trigger of the gun body 200, and make the firing pin of the gun body 200 strike the nail in the nail driving channel, driving out the nail and shaping it, thus completing the nail driving operation.

[0069] In summary, this utility model provides a palm pad gun for a nail feeding device, which offers stable nail pushing, simple operation, and low cost.

[0070] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
