DETAILED DESCRIPTION

[0026] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0027] The applicant believes that when the existing electric stapler is turned on, one only needs to pull down the handle and press the firing button, and the machine can start directly. Although the operation is relatively simple, there are also hidden dangers such as false triggering. Even if the electric stapler is in standby mode, if the firing button is accidentally touched, the electric stapler will continue to operate, posing a great safety hazard.

[0028] To this end, the applicant proposed an electric stapler anti-misfire safety structure, such as Figures 1-6 As shown, it includes a positioning handle 13, a lever 1, a safety block 2, a pin locking assembly, an excitation button 3, a second pin assembly, an excitation member tension spring 6, a third pin assembly, a front control switch 4 and a motor switch 5.

[0029] Among them, the shift lever 1 is rotatably installed on one side of the positioning handle 13, the safety block 2 is movably connected to a predetermined position on the positioning handle 13, the excitation button 3 is installed at the end of the positioning handle 13 and abuts against the safety block 2, the excitation member tension spring 6 is arranged between the positioning handle 13 and the excitation button 3, the front control switch 4 is arranged at a predetermined distance on the side of the excitation button 3 away from the safety block 2, and the motor switch 5 is arranged at a predetermined position on the front control switch 4.

[0030] The purpose of this application is that when the electric stapler is in operation, the trigger button 3 is easily triggered, so a safety structure is provided behind the trigger button 3 to prevent accidental triggering and the like, thereby increasing the safety of the device when in use.

[0031] During normal use, the device can be operated by turning the activation button 3 so that the activation button 3 touches the front control switch 4, and then the front control switch 4 touches the motor switch 5.

[0032] like Figure 2-Figure 3 As shown, the pin locking assembly is connected between the safety block 2 and the positioning handle 13 , and the pin locking assembly includes a locking groove 11 , a release groove 12 , a positioning protrusion 10 , a first pin hole and a safety pin 8 .

[0033] Among them, the locking groove 11 and the release groove 12 are respectively opened at predetermined positions on the positioning handle 13, and the positioning boss 10 is connected to the predetermined position on the safety block 2. The positioning boss 10 is adapted to the locking groove 11 and the release groove 12. When the positioning boss 10 slides into the locking groove 11, the safety block 2 is locked. When the positioning boss 10 slides into the release groove 12, the safety block 2 is released. The first pin hole is correspondingly opened on the safety block 2 and the positioning handle 13, and the safety pin 8 is adapted to the first pin hole. The safety pin 8 is inserted into the first pin hole, so that the safety block 2 is rotatably connected to the positioning handle 13.

[0034] In this application, the safety pin 8 is inserted into the connection between the safety block 2 and the positioning handle 13. When in use, the safety block 2 is toggled so that the positioning protrusion 10 on the safety block 2 slides into the release groove 12, and the safety block 2 and the trigger button 3 are released and can be toggled. The trigger button 3 is toggled so that the trigger button 3 touches the front control switch 4, and then the front control switch 4 touches the motor switch 5 to make the device operate. Conversely, the safety block 2 is toggled so that the positioning handle 13 on the safety block 2 slides into the locking groove 11, and the safety block 2 and the trigger button 3 are locked and cannot be toggled, so that the device enters the standby state and cannot be accidentally triggered and fired.

[0035] like Figures 1-6 As shown, the second pin assembly is connected between the excitation button 3 and the lever 1 and the positioning handle 13, the second pin assembly includes a second pin hole and a connecting rod pin 9, the third pin assembly is connected between the excitation member tension spring 6 and the positioning handle 13 and the excitation button 3, and the third pin assembly includes a spring pin 7 and a spring clamp 14.

[0036] Among them, the second pin hole is correspondingly opened on the excitation button 3, the deflector rod 1 and the positioning handle 13, the connecting rod pin 9 is adapted to the second pin hole, and the safety pin 8 is inserted into the second pin hole, so that the excitation button 3, the deflector rod 1 and the positioning handle 13 are rotatably connected, the spring pin 7 is installed at a predetermined position on the positioning handle 13, the spring clamp 14 is connected to the predetermined position on the excitation button 3, and the excitation member tension spring 6 is clamped between the spring pin 7 and the spring clamp 14, so that the excitation button 3 can be continuously deflected.

[0037] In this application, the spring pin 7 is inserted into the positioning handle 13, the connecting rod pin 9 is inserted into the connection between the excitation button 3 and the positioning handle 13, and the excitation member tension spring 6 connects the spring pin 7 and the excitation button 3, so that the corresponding components can be rotated and connected. This safety structure can effectively improve the safety of the device operation, increase the diversity of operation, greatly improve the controllability, etc.

[0038] Working principle: First, pull down the lever 1 to put the device into standby mode, then move the safety block 2 so that the positioning protrusion 10 on the safety block 2 slides into the release groove 12 on the positioning handle 13, and move the excitation button 3 connected to the excitation member tension spring 6 so that the excitation button 3 continuously touches the front control switch 4, and the front control switch 4 continuously touches the motor switch 5, and the device operates.

[0039] On the contrary, when the safety block 2 is turned, the positioning protrusion 10 on the safety block 2 slides into the locking groove 11 on the positioning handle 13. At this time, the safety block 2 and the trigger button 3 are locked. When the trigger button 3 is turned, the trigger button 3 cannot operate and cannot touch the front control switch 4, causing the device to enter the standby state.

[0040] It can be seen that with the presence of the safety block 2 and the pin locking assembly, the device can enter the standby state at any time during operation without worrying about accidental misfires, which greatly increases the safety and operability of the device.

[0041] As above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes in form and details may be made without departing from the spirit and scope of the present invention as defined in the appended claims.
