[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0020] Example 1, as Figure 1-4 As shown, this utility model provides a cutting device for processing leather products, including a cutting device body 1. A protective mechanism 2 is provided on the top side of the cutting device body 1. The protective mechanism 2 includes a fixing member 21. A first knob 22 is provided on one side of the fixing member 21. A bidirectional threaded rod 23 is provided inside the fixing member 21. A first bearing 24 is provided at both ends of the bidirectional threaded rod 23. A first slider 25 is provided on the surface of the bidirectional threaded rod 23. There are two first sliders 25. A limit ring 26 is provided in the middle of the bidirectional threaded rod 23. The two first sliders 25 One end of each device is equipped with a protective plate 27, and a lifting mechanism 3 is provided on one side of the protective mechanism 2. The protective mechanism 2 designed on the cutting device body 1 allows the user to close the two protective plates 27 on the protective mechanism 2 after using the cutting device body 1, preventing personnel from accidentally touching the cutting blade and causing injury when the device is idle. The lifting mechanism 3 allows the user to lift the opened protective mechanism 2 when using the cutting device body 1, thereby facilitating the user's cutting use of the cutting device body 1.
[0021] like Figure 2 and Figure 3 As shown, one end of the first knob 22 is fixedly connected to the bidirectional threaded rod 23, the surface of the bidirectional threaded rod 23 is fixedly connected to the inner surface of the two first bearings 24, and the outer surface of the two first bearings 24 is fixedly connected to the inner walls of both sides of the fixing member 21. The design of the first knob 22 makes it easy to rotate the bidirectional threaded rod 23. The design of the first bearings 24 enables the bidirectional threaded rod 23 to rotate stably inside the fixing member 21.
[0022] like Figure 3 As shown, the inner surface of the first slider 25 is threadedly connected to the bidirectional threaded rod 23, and the outer surface of the first slider 25 is slidably connected to the inner wall of the fixing member 21. The bidirectional threaded rod 23 is fixedly connected to the limiting ring 26. The first slider 25 is fixedly connected to one side of the protective plate 27. By rotating the bidirectional threaded rod 23, the two first sliders 25 can move inward synchronously, so that the protective plates 27 on both sides can block the cutting device body 1. The limiting ring 26 prevents the two first sliders 25 from contacting each other.
[0023] like Figure 2 and Figure 4 As shown, the lifting mechanism 3 includes a second knob 31, a screw 32 is provided at one end of the second knob 31, a second bearing 33 is provided on both ends of the screw 32, a second slider 34 is provided on the surface of the screw 32, a connecting member 37 is provided on one side of the fixing member 21, a limit post 35 is provided on the inner surface of the connecting member 37, a limit block 36 is provided at one end of the limit post 35, one end of the second knob 31 is fixedly connected to the screw 32, both ends of the screw 32 are fixedly connected to the inner surface of the second bearing 33, and the outer surfaces of the two second bearings 33 are fixedly connected to the cutting device body 1. The design of the second knob 31 makes it easy to rotate the screw 32, and the design of the second bearings 33 enables the screw 32 to rotate stably on the cutting device body 1.
[0024] like Figure 4 As shown, the inner surface of the second slider 34 is threadedly connected to the screw 32, one end of the second slider 34 is fixedly connected to the fixing member 21, the other side of the fixing member 21 is fixedly connected to the connecting member 37, the inner surface of the connecting member 37 is slidably connected to the limiting post 35, the bottom side of the limiting post 35 is fixedly connected to the cutting device body 1, and the limiting post 35 is fixedly connected to the limiting block 36. By rotating the screw 32, the fixing member 21 can only move up and down along the screw 32 with the second slider 34 under the limitation of the limiting post 35, so as to achieve the purpose of lifting the protective mechanism 2. The design of the limiting block 36 prevents the connecting member 37 from sliding out of the limiting post 35.
[0025] The usage and working principle of this device: Since the cutting device body 1 is existing technology, it will not be elaborated upon here. The protective mechanism 2 designed on the cutting blade of the cutting device body 1 prevents accidental contact and cuts when the device is not in use. Specifically, rotating the first knob 22 rotates the bidirectional threaded rod 23, which in turn causes the two first sliders 25 to move inward synchronously. This allows the two protective plates 27 to shield the cutting blade of the cutting device body 1, preventing accidental contact and injury. The lifting mechanism 3 allows the user to adjust the cutting... After opening, the protective mechanism 2 is raised so that it will not obstruct the cutting process during use. Specifically, rotating the second knob 31 causes the screw 32 to rotate, which in turn causes the second slider 34 to move the fixing member 21 upward. The design of the connecting member 37 and the limiting post 35 allows the fixing member 21 to move up and down stably. The design of the second knob 31 facilitates the rotation of the screw 32. The design of the second bearing 33 allows the screw 32 to rotate stably on the cutting device body 1. The design of the limiting block 36 prevents the connecting member 37 from sliding out of the limiting post 35.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
