[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] like Figure 1 — Fig.10 As shown, the improved nailing machine of the utility model includes a machine base 100 , a limiting plate 200 , a nail groove 210 , a locking groove 220 and a limiting block 230 .

[0028] In the utility model, the distances between the two side walls of the nail groove 210 and the limit block 230 are different, and the two side walls are named the first side wall 211 and the second side wall 212, the distance between the first side wall 211 and the limit block 230 is greater than the distance between the second side wall 212 and the limit block 230, the two side walls of the two locking grooves 220 are named the third side wall 221 and the fourth side wall 222, wherein the distance between the third side wall 221 and the limit block 230 is greater than the distance between the fourth side wall 222 and the limit block 230, and the side surface of the limit block 230 close to the first side wall 211 is called the limit surface.

[0029] In the present utility model, a staple with a width of 11.3 mm and a thickness of 0.7 mm is called a first nail, a staple with a width of 10.6 mm and a thickness of 1.2 mm is called a second nail, and a staple with a width of 7.7 mm and a thickness of 1.2 mm is called a third nail; wherein, the distance between the first side wall 211 and the second side wall 212 is equal to the width of the second nail, the distance between the limiting surface and the first side wall 211 is equal to the width of the third nail, and the distance between the third side wall 221 and the fourth side wall 222 is equal to the width of the first nail.

[0030] A limiting plate 200 for limiting the misaligned movement of staples is provided on one side of the base 100, a nail groove 210 is provided on one side surface of the limiting plate 200, and a clamping groove 220 is provided on both side walls of the nail groove 210, a limiting block 230 is movably installed in the limiting plate 200, a handle 300 is movably installed on the base 100, a return spring (not marked in the figure) is provided between the handle 300 and the base 100, an elastic plate 130 connected to a movable plate 400 is provided in the base 100, and a movable plate 400 is movably provided on one side of the limiting plate 200 of the base 100, and an impact plate 410 is provided at the bottom end of the movable plate 400, and the impact plate 410 can pass through the clamping groove 220, the machine base 100 is provided with a shell 500 on one side of the limit plate 200, and the other side of the limit block 230 is provided with a spring plate 231, which is curved, and the middle part of the spring plate 231 abuts against the inner wall of the shell 500. The bottom of the machine base 100 is provided with a nail feeding assembly 600, and the nail feeding assembly 600 includes a nail pushing seat 610, and a nail pushing plate 620 is movably provided on the nail pushing seat 610, and one end of the nail pushing seat 610 is directly opposite to the nail groove 210. Before use, people can put a group of staples of corresponding specifications into the nail pushing seat 610 according to needs, and the nail pushing plate 620 abuts against one end of a group of staples. Because the nail pushing plate 620 and the nail pushing seat 610 are connected by a first spring, the nail pushing plate 620 and the nail pushing seat 610 are connected. The spring (not marked in the figure) is connected so that the nail pushing plate 620 can push the stapler to move in the direction of the limiting plate 200, and the impact plate 410 at this time just passes through the positioning groove 220, so that the stapler away from the nail pushing plate 620 presses against the upper surface of the impact plate 410, and when people press the handle 300, the end of the handle 300 will drive the movable plate 400 to move away from the limiting plate 200, that is, the movable plate 400 will move upward with the impact plate 410, and the elastic plate 130 will be deformed accordingly and generate elastic force with the movable plate 400, the reset spring will be deformed and generate elastic force, so that the impact plate 410 will move from the positioning groove 220, and the stapler located on the nail pushing seat 610 will be pressed. The stapler will always be pushed by the staple pusher plate 620, so that the stapler continues to move toward the staple groove 210 until the stapler away from the staple pusher plate 620 is embedded in the staple groove 210 or the positioning groove 220. When the handle 300 rises to a predetermined height with the movable plate 400, the handle 300 separates from the movable plate 400, so that the movable plate 400 is accelerated to move toward the limiting plate 200 under the action of the elastic plate 130 until the impact plate 410 is inserted into the positioning groove 220. The limiting plate 200 restricts the movement of the movable plate 400. During this process, the impact plate 410 pushes the stapler out of the staple groove 210 or directly out of the positioning groove 220, thereby completing the entire process of the nailing machine ejecting staples.

[0031] Further, the nail pusher seat 610 includes a bottom plate 611, on which a guide seat 612 and a partition plate 613 are installed, the partition plate 613 is arranged on one side of the guide seat 612, and a guide shell 614 is installed on the base, and the guide seat 612 and the partition plate 613 are both located in the guide shell 614, wherein the gap between the guide seat 612 away from the partition plate 613 and the guide shell 614 is called a first gap, the gap between the guide seat 612 and the partition plate 613 is called a second gap, and the gap between the partition plate 613 away from the guide seat 612 and the guide shell 614 is called a third gap, and the first gap, the second gap and the third gap are all parallel to each other; when the first nail is selected When the second nail is selected, one end of the first nail will be directed to move through the first gap, and the other end of the first nail will be directed to move through the third gap. Specifically, the end of the first nail located in the third gap will be directed to move against the inner wall of the guide shell 614, and the end of the first nail located in the third gap will not contact the partition plate 613. In this way, it can be ensured that the first nail can be smoothly embedded in the positioning groove 220. Thereafter, when the impact plate 410 rushes into the positioning groove 220, the impact plate 410 pushes the first nail out of the positioning groove 220. When the second nail is selected, one end of the second nail will be directed to move through the first gap, and the other end of the second nail will be directed to move through the third gap. Specifically, the end of the second nail located in the third gap will be against the inner wall of the guide shell 614. The second nail moves in a directional manner along the surface of the partition plate 613, and the end of the second nail located in the third gap will not contact the inner wall of the guide shell 614, so that the second nail can be smoothly embedded between the first side wall 211 and the second side wall 212 of the nail groove 210. Specifically, when the second nail is embedded in the nail groove 210, the second nail will push the limiting block 230 to retract into the limiting plate 200 to prevent the limiting block 230 from affecting the second nail. At the same time, because the thickness of the second nail is greater than the thickness of the first side wall 211 and less than or equal to the combined thickness of the first side wall 211 and the third side wall 221, a part of the second nail will be located in the positioning groove 220. In this way, when the impact plate 410 rushes into the positioning groove 220, When the third nail is used, one end of the third nail will be directed through the first gap and the other end of the third nail will be directed through the second gap. In this way, the third nail can be smoothly embedded between the first side wall 211 and the limiting wall of the nail groove 210. When the third nail is embedded in the nail groove 210, because the thickness of the third nail is greater than the thickness of the first side wall 211 and less than or equal to the combined thickness of the first side wall 211 and the third side wall 221, a part of the third nail will be located in the locking groove 220. In this way, when the impact plate 410 rushes into the locking groove 220, the impact plate 410 pushes the third nail out of the locking groove 220.

[0032] Furthermore, a fixing rod 110 is provided in the machine base 100, and a waist hole 310 is opened on the handle 300 for the fixing rod 110 to pass through. A disengagement groove 320 is provided at the bottom of the handle 300, and a disengagement rod 120 is provided in the machine base 100. When people rotate the handle 300 around the fixing rod 110 to a predetermined angle, the disengagement groove 320 contacts the disengagement rod 120. At this time, the handle 300 will rotate around the disengagement rod 120, and the handle 300 will move along the trajectory of the waist hole 310 in the direction away from the movable plate 400, that is, the fixing rod 110 is transferred from the right end of the waist hole 310 to the left end of the waist hole 310 to achieve the separation of the handle 300 and the movable plate 400.

[0033] When the nailing machine is not in use, the middle part of the spring plate 231 abuts against the shell 500, so that one side of the limit block 230 is embedded in the nail groove 210, and the connection between the locking groove 220 and the nail groove 210 is flush with the side. When the limit block 230 is pushed by the second nail, the limit block 230 will retract into the limit plate 200. At the same time, the spring plate 231 is deformed by the force and generates corresponding elastic force. When the limit block 230 is no longer pushed by the second nail, the elastic force on the spring plate 231 will push the limit block 230 to reset.

[0034] The limiting plate 200 is provided with limiting blocks 232 at both ends of one side of the spring plate 231. The distance between the middle of the spring plate 231 and the limiting block 230 is greater than the distance between the limiting block 232 and the limiting block 230. The width of the limiting block 232 is greater than the width of the limiting block 230. The limiting plate 200 is provided with a through hole 240 for the limiting block 230 to pass through. The width of the through hole 240 is greater than or equal to the width of the limiting block 230, and the width of the through hole 240 is less than the width of the limiting block 232. The limiting block 232 is located in the receiving groove 251, and the distance between the middle of the spring plate 231 and the bottom surface of the receiving groove 251 is greater than the thickness of the receiving groove 251. The setting of the limiting block 232 can prevent the spring plate 231 from passing through the through hole 240 into the nail groove 210, and can also ensure that the side of the limiting block 230 facing the nail pushing seat 610 is flush with the connection between the positioning groove 220 and the nail groove 210.

[0035] There is an angle a between the side wall of the nail groove 210 and the normal of the nail groove 210, and the angle a is 5°. Through the setting of the angle a, the second nail and the third nail can play a guiding role when entering the nail groove 210, so that the second nail and the third nail can smoothly enter the nail groove 210.
