[0057] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0058] To enable the stapler to combine status indication and automatic unlocking for firing, thereby reducing the stapler failure rate, this embodiment provides a stapler with status indication and automatic safety. The following describes the implementation in conjunction with... Figures 1 to 8 The specific content of this embodiment will be described in detail. It should be noted that the first direction mentioned in this embodiment is... Figure 1 The X direction in the equation.

[0059] The stapler with status indication and automatic safety in this embodiment includes a hollow fixed handle 1, a lead screw 2, a firing handle 3, and a bent push tube 4. The lead screw 2 is disposed within the fixed handle 1 and can move along a first direction. The portion of the bent push tube 4 located in the fixed handle 1 is hinged to the firing handle 3. Holding the firing handle 3 allows the bent push tube 4 to move along the first direction. The stapler with status indication and automatic safety also includes an indicator 5, a guide 6, a safety linkage 7, an adjusting member 8, and an adjusting seat 9. The indicator 5 is slidably disposed within the fixed handle 1 and has a firing indicator and a locking indicator. The guide 6 is fixedly disposed within the fixed handle 1 and has a guide groove 601 extending along the first direction. The first end of the safety linkage 7 is hinged to the firing handle 3, and the second end of the safety linkage 7 is located within the guide groove 601. The adjusting element 8 is slidably disposed within the fixed handle 1. One end of the adjusting element 8 is provided with a lever 801, which is used to lock or unlock the safety linkage 7 against the inner wall of the guide groove 601. The adjusting seat 9 is fixedly sleeved on the lead screw 2. Both the indicator 5 and the adjusting element 8 are connected to the adjusting seat 9 in a transmission manner. The adjusting seat 9 is used to drive the indicator 5 and the adjusting element 8 to move along the first direction.

[0060] In summary, the stapler with status indication and automatic safety provided by this invention has a guide member 6 with a guide groove 601 installed in the fixed handle 1. The second end of the safety linkage 7 is located in the guide groove 601. The adjusting seat 9 is fixedly mounted on the lead screw 2. The indicator 5 and the adjusting member 8 are both linked to the adjusting seat 9. When the lead screw 2 moves the adjusting seat 9 together, on the one hand, when the adjusting seat 9 drives the indicator 5 to slide along the first direction, the stapler can display the firing indicator or locking indicator of the indicator 5; on the other hand, when the adjusting seat 9 drives the adjusting member 8 to slide along the first direction, the lever 801 can drive the safety linkage 7 to unlock or lock against the inner wall of the guide groove 601. With simple operation of the lead screw 2, the stapler can have both status indication and automatic unlocking and firing functions, simplifying the internal structure and reducing the failure rate of the stapler.

[0061] Furthermore, the fixed handle 1 is provided with a window 101. The stapler with status indication and automatic safety also includes a window cover 10, which is fastened to the window 101. The window cover 10 has a transparent area 1001, which is used to display the firing indicator or the locking indicator. By adding the window cover 10, it serves two purposes: firstly, to display the indicator, and secondly, to cover the window 101, preventing dust and other contaminants from entering the fixed handle 1.

[0062] Furthermore, the guide groove 601 has a square structure, and a square limiting post 701 is provided at the second end of the safety link 7. The square limiting post 701 is located inside the guide groove 601. When the outer wall surface of the square limiting post 701 abuts against the inner wall surface of the guide groove 601, it prevents the safety link 7 from accidentally falling off and keeps the safety link 7 in a locked state.

[0063] Furthermore, the inner wall of the guide groove 601 is provided with a guide slope 6011. When the adjusting seat 9 moves, the paddle 801 of the adjusting member 8 moves the square limiting post 701, causing the square limiting post 701 to separate from the inner wall of the guide groove 601. By providing the guide slope 6011 on the inner wall of the guide groove 601, the square limiting post 701 can slide along the guide slope 6011, which helps to improve the smoothness of the rotation of the firing handle 3.

[0064] Furthermore, the paddle 801 is made of magnetic material, and the safety linkage 7 is made of ferromagnetic metal. When the adjusting component 8 and the paddle 801 are reset, the paddle 801 can attract the safety linkage 7 from the unlocked state to the locked state under the action of magnetic force, so that the square limiting post 701 of the safety linkage 7 abuts against the inner wall surface of the guide groove 601 again, completing the reset of the safety linkage 7.

[0065] Furthermore, the stapler with status indication and automatic safety also includes a rotating component 11 and a guide pin 12. The rotating component 11 is rotatably mounted within the fixed handle 1, and the lead screw 2 passes through the rotating component 11. The guide pin 12 is inserted radially into the rotating component 11, with one end extending into the threaded groove of the lead screw 2. By rotating the rotating component 11 and the guide pin 12, the guide pin 12 moves along the threaded groove of the lead screw 2, causing the lead screw 2 to move in a first direction.

[0066] Furthermore, a ring-shaped limiting part 102 is fixedly provided inside the fixed handle 1, the indicator 5 is provided with a first guide groove 501 extending along a first direction, and a first boss 901 is provided on the adjusting seat 9. The first boss 901 slides through the first guide groove 501. The stapler with status indication and automatic safety also includes a first elastic element 13, which is sandwiched between the ring-shaped limiting part 102 and the indicator 5. For example, the first elastic element 13 is a spring. By moving the first boss 901 in the first guide groove 501, the indicator 5 can move with the adjusting seat 9, causing the first elastic element 13 to be compressed and shortened. When reset is required, the lead screw 2 drives the adjusting seat 9 to move, and the indicator 5 resets under the action of the first elastic element 13.

[0067] Furthermore, one end of the indicator 5 is provided with an external rod portion 502, and the annular limiting portion 102 is provided with a first clearance hole 1021 corresponding to the external rod portion 502. The first elastic member 13 is sleeved on the external rod portion 502, and the external rod portion 502 passes through the first clearance hole 1021. By adding the external rod portion 502, the installation of the first elastic member 13 is facilitated. By adding the first clearance hole 1021, structural interference between the external rod portion 502 and the annular limiting portion 102 during movement is avoided.

[0068] Furthermore, the adjusting member 8 is provided with a second guide groove 802 extending along the first direction, and the adjusting seat 9 is provided with a second boss 902. The second boss 902 slides through the second guide groove 802. The stapler with status indication and automatic safety also includes a second elastic member 14, which is sandwiched between the annular limiting part 102 and the adjusting member 8. Exemplarily, the second elastic member 14 is a spring. By moving the second boss 902 within the second guide groove 802, the adjusting member 8 can move with the adjusting seat 9, causing the second elastic member 14 to be compressed and shortened. When reset is required, the adjusting member 8 automatically resets under the action of the second elastic member 14.

[0069] Furthermore, the stapler with status indication and automatic safety also includes a fixing pin 16. The adjusting seat 9 is provided with a pin hole, and the fixing pin 16 is inserted into the pin hole and abuts against the lead screw 2. By adding the fixing pin 16, the connection between the adjusting seat 9 and the lead screw 2 is ensured to be stable.

[0070] The stapler with status indicators and automatic safety provided in this embodiment not only displays safety prompts but also automatically unlocks and fires upon reaching the safe zone. After firing, the safety automatically resets. The specific working principle is as follows:

[0071] The instrument includes a lead screw 2 that passes through a rotating component 11. A guide pin 12 is built into the rotating component 11. The protruding part of the guide pin 12 acts on the threaded groove of the lead screw 2, controlling its left and right movement. An adjusting seat 9 is provided on the lead screw 2. The adjusting seat 9 has a first boss 901 and a second boss 902, which act on the indicating component 5 and the adjusting component 8, respectively. In the initial position, the adjusting seat 9 is at the far right, and the adjusting component 8 is also at the far right. The firing handle 3 is equipped with a handle positioning pin 31. The safety link 7 is installed on the firing handle 3 through the handle positioning pin 31 and can rotate freely. On the other side of the safety link 7, there is a square limiting post 701 that contacts the guide groove 601 of the guide component 6. In the initial position, the firing handle 3 is limited by the safety link 7. When working, rotating the rotating component 11 causes the lead screw 2 to move the adjusting seat 9 to the left, which in turn moves the indicator 5 and the adjusting component 8 to the left. At the same time, the adjusting component 8 moves the safety link 7 to the left and into the guide slope 6011. At this time, the firing indicator (which can be a red area) on the indicator 5 will be exposed in the viewing window cover 10. The safety link 7 has been released from restriction, and the firing handle 3 can be fired normally. After firing, the firing handle 3 is reset under the action of the third elastic element 15. The rotating part 11 is rotated counterclockwise, and the adjusting seat 9 moves to the right. At the same time, the indicator 5 and the adjusting part 8 will move to the right along with the two bosses of the adjusting seat 9 through two corresponding reset springs. Since the paddle 801 of the adjusting part 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 post 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 (which can be the red area) leaves the window cover 10, and the locking indicator (which can be the green area) will be exposed in the window cover 10.

[0072] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
