When the operator pulls the push nail hook ear 42 to overcome the elastic force of the push nail spring 6 and move backward to the tail end, the boss 43 of the push nail block 4 drives the push rod 201 to move backward, so that the extrusion slope 2011 at the front end is separated from the cover plate slot 32, as shown in FIG. Fig.31 As shown, the push rod 201 pushes the rotating buckle 203 to overcome the force of the first reset torsion spring 204 and rotate upward until it hits the limit pin 207. Because the push rod inclined surface 2011 at the front end of the push rod 201 is separated from the cover plate slot 32, the cover plate 3 will bounce up under the elastic force of the cover plate torsion spring 18, as shown in FIG. Fig.32 When the operator pulls the handle to a certain position and releases his hand, the rotating buckle 203 will be inserted into and block the push nail hook ear 42, preventing the push nail block 4 from moving forward under the force of the push nail spring 6, as shown in FIG. Fig.33 At this time, the row of nails 7 can be loaded into the nail slot 22 through the nail loading opening 21 of the nail magazine 2, as shown. Fig.34 , Fig.37 , Fig.38 After the nail row 7 is installed, press down the cover plate 3, see Fig.35 , the bevel 33 of the cover plate 3 will squeeze the squeezing bevel 2011 of the push rod 201, so that the push rod 201 retreats, pushing the rotating buckle 203 to rotate upward, and at the same time, the nail pushing block hook ear 42 will break away from the obstruction of the rotating buckle 203, and move forward under the thrust of the nail pushing spring 6 until the nail pushing block 4 is pushed to the position, such as Fig.36 The whole process is reduced to two actions, one is to pull and push the nail block 4, and the other is to press the cover plate 3, so that the nailing linkage process can be completed.

[0083] See also Figures 1 to 42 A method for using a hammer with a nail magazine of the present invention comprises the following steps:

[0084] Step 1, insert the row of nails 7 into the nail slot 22 of the nail magazine 2;

[0085] The operator pulls the hook ear 42 of the nail pushing block, and the boss 43 links the push rod 201 to move away from the cover plate 3, so that the push rod 201 is disengaged from the cover plate slot 32, and the cover plate 3 is bounced open under the elastic force of the cover plate torsion spring 18; at the same time, the rotating buckle 203 tilts upward, releasing the hook ear 42 of the nail pushing block, and the rotating buckle 203 rotates and cooperates with the hook ear 42 of the nail pushing block to stop, limiting the return of the nail pushing block 4 under the action of the nail pushing spring 6, and the row of nails 7 are installed into the nail slot 22, and the cover plate 3 is pressed down. The bevel 33 of the plate 3 squeezes the squeezing bevel 2011 of the push rod 201, causing the push rod 201 to move away from the cover plate 3, driving the rotating buckle 203 to tilt upward, releasing the hook ear 42 of the nail pushing block, and the nail pushing block 4 is reset under the action of the nail pushing spring 6 to press the row of nails 7; when the cover plate 3 continues to be pressed down to the state of closing the nailing opening 21, the rotating buckle 203 pushes the push rod 201 under the action of the first reset torsion spring 204 to snap into the cover plate slot 32 and lock the cover plate 3; the nailing action is completed. Figures 30 to 36 shown.

[0086] Step 2, nailing;

[0087] The operator swings the hammer to hit the wooden board. Due to the weight of the hammer 11 itself and a certain speed, the hammer 11 moves forward along the nail channel 85 under the action of inertia, and pushes the upper nail 71 out of the nail channel 85. At the same time, when the hammer 11 moves to the bottom of the stroke, the pawl 192 is engaged with the ratchet groove 191, so that the hammer 11 is locked relative to the main body seat 8. The energy released by the huge inertia force of the hammer 11 hits the upper nail 71, so that the nail quickly penetrates into the wooden board and will not be pulled out even if the hammer is raised back. Then continue to swing the hammer back and forth, and use the hammer head 9 to completely drive the nail into the wooden board.

[0088] Step 3, resetting the hammer 11;

[0089] Before the operator swings the hammer to hit the board, he should check whether the hammer 11 has returned to its initial position. This is because after the last nailing, when the hammer 11 hits the bottom of its stroke due to the inertia, the ratchet 192 can get stuck in the ratchet groove 191 of the hammer 11, so that the hammer 11 cannot be reset under the action of the guide rod reset spring 153. Fig.39 , Fig.40 If it does not return to the initial position, the upper nail 71 in the nail magazine 2 cannot enter the nail outlet channel 85, and the next nailing operation cannot be performed.

[0090] The operator holds the handle 1 and swings it clockwise. Fig.41 As shown, due to the inertia, a counterclockwise force is generated, so that the swing block 196 overcomes the force of the second reset torsion spring 195 and rotates, twisting the rotating rod 193 to drive the pawl 192 from Fig.39 The position is reversed to Fig.40The position of the hammer 11 is disengaged from the ratchet groove 191, and the hammer 11 can be reset to the initial position under the action of the guide rod reset spring 153, and the nailing step can be performed. After the hammer 11 is reset, the swing block 196 will be reset under the action of the second reset torsion spring 195.

[0091] Example 2

[0092] The difference between this embodiment and the first embodiment is that the cover plate 3 is hinged on the nail box 2. The horn nail remover 12 and the sleeve cylinder 10 are set as an integral structure. The nailing method of step 2 is: the operator swings the hammer and lightly hits the wooden board. The hammer 11 moves forward along the nailing channel 85 due to inertia, pushing the upper nail 71. When it hits the bottom of its stroke, the tip of the upper nail 71 extends out of the front plane of the hammer head 9 by a certain length, such as Figure 6 At this time, the ratchet 192 is inserted into the ratchet groove 191 of the hammer 11, so that the hammer 11 stops at the bottom of the stroke and is locked relative to the main body 8; the operator then swings the hammer and strikes the position where the nail is to be driven, and the tip of the upper nail 71 can penetrate into the wooden board, and will not be pulled out even if the hammer is raised back; then the hammer is continued to be swung back and forth, and the nail is completely driven into the wooden board using the hammer head 9.

[0093] The above are only two specific implementations of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
