[0071] The stapler with status prompt and automatic safety provided in this embodiment can not only display safety prompts, but also automatically unlock and fire after reaching the safe area. After firing, the safety will automatically reset. The specific working principle is as follows:

[0072] The instrument is provided with a lead screw 2, which passes through a rotating member 11, and a guide pin 12 is built into the rotating member 11. The raised portion of the guide pin 12 acts on the thread groove of the lead screw 2 to control the left and right movement of the lead screw 2. An adjustment seat 9 is provided on the lead screw 2, and a first boss 901 and a second boss 902 are provided on the adjustment seat 9. The first boss 901 and the second boss 902 act on the indicator 5 and the adjustment member 8 respectively. When the instrument is in the initial position, the adjustment seat 9 is at the rightmost end, and the adjustment member 8 is also at the rightmost end. A handle locating pin 31 is installed on the firing handle 3. The safety link 7 is installed on the firing handle 3 through the handle locating pin 31 and can rotate freely. A square limiting column 701 is provided on the other side of the safety link 7 to contact the guide groove 601 of the guide member 6. If it is in the initial position, the firing handle 3 will be limited by the safety link 7. When working, the rotating member 11 is rotated to make the screw 2 drive the adjustment seat 9 to move to the left, and at the same time, it will drive the indicator member 5 and the adjustment member 8 to move to the left. At the same time, the adjustment member 8 will drive the safety link 7 to move to the left and enter the guide slope 6011. At this time, the firing indication mark (which can be a red area) provided on the indicator member 5 will be revealed in the window cover 10, and the safety link 7 has been released from the restriction. The firing handle 3 can be fired normally by holding it. After the firing is completed, the firing handle 3 is reset under the action of the third elastic member 15, the rotating member 11 is rotated counterclockwise, the adjusting seat 9 moves to the right, and at the same time, the indicating member 5 and the adjusting member 8 will follow the two bosses of the adjusting seat 9 to move to the right through two corresponding reset springs. Because the paddle 801 of the adjusting member 8 attracts the safety link 7 by magnetic force, the paddle 801 will drive the safety link 7 back to the initial position. At this time, the square limit column 701 on the safety link 7 also returns to the initial position. At this time, the handle cannot be fired. At this time, the firing indicator mark (which can be the red area) leaves the window cover 10, and the locking indicator mark (which can be the green area) will be revealed in the window cover 10.
