DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 , the utility model provides the embodiment:

[0024] A stapler with a protective structure comprises a stapler body 1, a handle 2 is installed on the lower side of the stapler body 1, a trigger 3 is rotatably installed on the lower side of the stapler body 1, a safety component is installed on one side of the trigger 3, a protection component is installed on one end of the stapler body 1, the safety component comprises a protection rod 4, the protection rod 4 is rotatably installed on one side of the trigger 3, a safety block 5 is installed on the other side of the protection rod 4, a sliding groove is opened on one side of the handle 2, the safety block 5 is slidably installed in the sliding groove, the inner wall of the sliding groove is installed with a mounting hole, and a fixing unit is installed in the mounting hole.

[0025] Based on the above structure, a handle 2 is installed on the lower side of the stapler body 1, and the internal firing structure thereof is consistent with the technology disclosed in the above-mentioned referenced documents. The entire stapler is fired by the firing device 3 for use. A safety component is arranged at the position of the firing device 3. When not in use, the safety block 5 can be limited by the fixing unit so that the safety block 5 can no longer slide in the arc-shaped sliding groove, thereby making the protective rod 4 unable to move, thereby locking the firing device 3. A protection component is also arranged at the firing end of the stapler body 1 to protect the end part from contamination.

[0026] Example 1

[0027] like Figure 2 and 3 As shown, the fixing unit includes a limiting ring 6, which is slidably installed in the mounting hole, a plug-in block 7 is installed on one side of the limiting ring 6, a safety groove is provided on one side of the safety block 5, and the safety groove matches the plug-in block 7, a pull rod 8 is installed on one side of the limiting ring 6, a pressure ring 9 is installed in the mounting hole, a first avoidance hole is provided on one side of the pressure ring 9, and a first spring 11 is sleeved and installed on the surface of the pull rod 8. The first spring 11 acts on the limiting ring 6 to make the plug-in block 7 close to the safety groove, thereby limiting the safety block 5.

[0028] like Figure 2 and 3As shown, a pull block 10 is installed at one end of the pull rod 8. When the pull block 10 is pulled, the pull block 10 drives the pull rod 8 to move, and the pull rod 8 drives the limit ring 6. The limit ring 6 drives the plug-in block 7 away from the safety block 5, so that the safety block 5 is unlocked and can slide in the sliding groove, thereby causing the protective rod 4 to move, allowing the firing device 3 to fire normally, avoiding accidental contact.

[0029] Example 2

[0030] like Figure 4 As shown, the protection assembly includes a sub-shield 12, a main shield 13 is rotatably mounted on one side of the sub-shield 12, a locking unit is mounted on the surface of the sub-shield 12, and semicircular cylindrical grooves are provided on the inner walls of the sub-shield 12 and the main shield 13 to wrap the firing end.

[0031] like Figure 4 As shown, the locking unit includes a snap-in block 14, which is mounted on the surface of the sub-cover 12, and a mounting box 15 is mounted on the surface of the mother cover 13. A locking groove is provided on one side of the mounting box 15, and the locking groove matches the snap-in block 14. A slide groove is provided on the lower side of the mounting box 15, and a limiting unit is installed in the slide groove. The locking groove leaves a partial movable position to facilitate the insertion of the snap-in block 14 into the mounting box 15.

[0032] like Figure 4 As shown, the limit unit includes a limit block 16, which is slidably installed in the slide groove. A mounting opening is opened on one side of the limit block 16, and a connecting rod 17 is installed in the mounting opening. A sliding hole is opened on the inner top wall of the slide groove, and the connecting rod 17 is slidably installed in the sliding hole. An unlocking block 18 is installed at the other end of the connecting rod 17, and the unlocking block 18 matches the clamping block 14. A pressing block 19 is installed on the inner wall of the slide groove, and a second avoidance hole is opened on one side of the pressing block 19. A second spring 21 is sleeved on the surface of the connecting rod 17.

[0033] like Figure 4 As shown, a pull ring 20 is installed at one end of the connecting rod 17, and the sub-protective cover 12 and the main protective cover 13 are closed tightly against the surface of the working end of the stapler body 1, so that the clamping block 14 is inserted into the installation box 15, and the pull ring 20 is pulled at the same time. The pull ring 20 drives the connecting rod 17 to move, and the connecting rod 17 drives the unlocking block 18 to move, so that the unlocking block 18 is away from the clamping block 14. When the clamping block 14 is fully extended into the installation box 15, the pull ring 20 is released, and the limit block 16 is driven to move by the action of the second spring 21, and the limit block 16 drives the connecting rod 17 to move, and the connecting rod 17 drives the unlocking block 18 to limit the clamping block 14, so that the sub-protective cover 12 is connected to the main protective cover 13.

[0034] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
