A brake switch 67 for controlling the power supply is provided on the upper side of the connecting rod 65.

[0031] The safety assembly 3 includes a safety rod 31, which is arranged on one side of the impact hammer 63. The upper end of the safety rod 31 is laterally connected to a connecting rod 32. A locking rod 33 is arranged at one end of the connecting rod 32 away from the safety rod 31. The locking rod 33 is vertically arranged, and a bend is formed on the locking rod 33 to cooperate with the locking of the trigger assembly 2. A safety micro switch 34 is installed on the upper side of the top of the connecting rod 32.

[0032] In this embodiment, the trigger assembly 2 includes a trigger block 21, which is installed on the handle portion of the housing 1 through a rotating shaft. A push rod 22 is provided on the side of the trigger block 21 corresponding to the locking rod 33. A trigger rod 24 is installed inside the trigger block 21. One end of the trigger rod 24 corresponds to the connecting rod 65, and the other end of the trigger rod 24 corresponds to the power switch 23. The power switch 23 is installed on the upper side of the trigger block 21.

[0033] In this embodiment, the depth adjustment assembly 5 includes a height adjustment block 53, which is divided into a connecting rod part and an adjustment part. The upper end of the safety rod 31 is connected to the connecting rod part of the height adjustment block 53, and the adjustment part of the height adjustment block 53 is threadedly connected to an adjustment shaft 52. The upper end of the adjustment shaft 52 passes through the housing 1, and the top of the adjustment shaft 52 is connected to an adjustment knob 51.

[0034] In this embodiment, the adjustment component 4 includes a rotating block 41, which is connected to the casing 1 through a connecting shaft. Four different patterns are distributed on the circumference of the outer surface of the rotating block 41. The rotating block 41 is formed with a groove corresponding to the inner surface of the casing 1, and a locking bead 42 is provided on the casing 1. The locking bead 42 is installed in a slide groove of the casing 1, and a spring supporting the locking bead 42 is installed in the slide groove. The locking bead 42 corresponds to the position of the groove of the rotating block 41.

[0035] In this embodiment, the safety lever 31 , the connecting rod 32 , and the locking rod 33 are integrally formed, and the safety lever 31 is slidably connected to the housing 1 .

[0036] In this embodiment, the top of the connecting rod 32 cooperates with the housing 1 via a return spring.

[0037] In this embodiment, a vertical rod is formed in the middle of the linkage rod 65, and a return spring is installed on the vertical rod. The linkage rod 65 cooperates with the housing 1 through the return spring of the vertical rod.

[0038] Working principle: when the device is picked up, the bottom of the safety rod 31 is not subjected to pressure, so the safety rod 31 will not retract into the housing 1. At this time, the safety rod 31, the connecting rod 32, and the locking rod 33 are compressed to the nailing hole position of the housing 1 by the return spring, and the safety rod 31, the connecting rod 32, and the locking rod 33 are all in a sunken state. When the locking rod 33 sinks, the bent part of the top is just stuck with the end face of the top rod 22 on the side of the trigger 21. At this time, even if the trigger 21 is pulled, the top rod 22 is also stuck with the locking rod 33, and the trigger 21 cannot be pulled. At the same time, because the locking rod 33 is in a sunken state, the locking rod 33 is separated from the safety micro switch 34. When the safety micro switch 34 is not triggered, the device is not powered on and cannot be started.

[0039] When nailing is required, the housing 1 is picked up and the safety rod 31 is pressed on the surface to be processed, the safety rod 31 is compressed into the housing 1, the safety rod 31, the connecting rod 32, and the locking rod 33 move upward, the locking rod 33 is separated from the top rod 22, the trigger 21 can be pulled, and the locking rod 33 moves upward to trigger the safety micro switch 34, and the subsequent circuit is connected;

[0040] When the power motor 61 rotates, the cam plate 62 rotates clockwise, and the cam plate 62 rotates and drives the linkage rod 65 upward, and the linkage rod 65 moves upward to push the trigger rod 24 to rotate, so that the other end of the linkage rod 65 is disengaged from the contact with the power switch 23, and the power switch 23 is powered off. However, at this time, the brake switch 67 has been turned on and powered on because the linkage rod 65 moves upward, and the brake switch 67 is still powered on when it moves upward; that is, the brake switch 67 is powered on first, and then the power switch 23 is powered off.

[0041] Because the cam plate 62 rotates one circle, the notch of the cam plate 62 is realigned with the connecting rod 65, so that the connecting rod 65 is no longer supported by the cam plate 62, and under the restoring force of the spring, it returns to its original position, causing the brake switch 67 to be disengaged and powered off. At this time, the motor 25 and the brake switch 67 are both powered off, and the entire machine is powered off, achieving a brake stop and preparing for the second cycle;

[0042] When the machine is stopped, if it is necessary to adjust the extended length of the safety rod 31, it is only necessary to rotate the adjusting knob 51. The adjusting knob 51 drives the adjusting shaft 52 to cooperate with the height adjusting block 53, so that the height adjusting block 53 is adjusted to rise and fall by the threaded cooperation, thereby driving the safety rod 31 to rise and fall, and then adjusting the extended length of the safety rod 31; at the same time, according to the extended length corresponding to different materials to be processed and corresponding to different nails, the rotating block 41 can be rotated, and after the rotating block 41 is rotated, it is squeezed and cooperated with the locking bead 42 and the groove, thereby fixing the position of the rotating block 41.

[0043] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
