[0021] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0022] Referring to Figures 1-4 , an embodiment of a combined special-shaped fastener of the present utility model includes: a bottom plate 1, which serves as the basic support component of the entire fastener. The left surface of the bottom plate 1 is fixedly connected with a left limit plate 3 for restricting and positioning the material to be fixed. The right surface of the bottom plate 1 is fixedly connected with a right limit plate 2 for restricting and positioning the material to be fixed. Cavities 8 are provided inside both the left limit plate 3 and the right limit plate 2 to provide space for the movement of the limit rod 5. Moving holes 9 are provided on the right surface of the left limit plate 3 and the left surface of the right limit plate 2 to enable the limit rod 5 to extend or retract. The moving holes 9 penetrate the cavities 8. A limit rod 5 is movably connected inside the moving holes 9 to prevent the movement of the fixed plate 4. The limit rod 5 extends into the cavity 8. A baffle 10 is fixedly connected to the side surface of the limit rod 5 to push the limit rod 5 to move.

[0023] Return springs 7 are fixedly connected to the left inner wall of the left limit plate 3 and the right inner wall of the right limit plate 2 to provide the force required for the limit rod 5 to return. The limit rod 5 is located at the center of the return spring 7. One end of the return spring 7 away from the inner wall is fixedly connected to the baffle 10. The baffle 10 covers the moving hole 9. Both the return spring 7 and the baffle 10 are located inside the cavity 8. A bolt 6 is threadedly connected to the upper surface of the bottom plate 1. A fixed plate 4 is threadedly connected to the side surface of the bolt 6. The fixed plate 4 is located directly above the bottom plate 1 and between the left limit plate 3 and the right limit plate 2. A nut 11 is threadedly connected to the lower end of the bolt 6 to fix the bolt 6 on the bottom plate 1. A protection groove 12 is provided on the lower surface of the bottom plate 1 to accommodate and protect the nut 11. The nut 11 is located inside the protection groove 12. The bolt 6 penetrates the bottom plate 1 and extends into the protection groove 12.

[0024] Working principle: The left limit plate 3 and the right limit plate 2 are respectively fixed on the left and right sides of the bottom plate 1, and they both have cavities 8 and moving holes 9 inside. The moving hole 9 allows the limit rod 5 to move inside the cavity 8. When it is necessary to limit the position of an object (such as a workpiece), the limit rod 5 is pushed out from the inside of the cavity 8 under the action of the return spring 7, and through the moving hole 9, it protrudes from the surface of the left limit plate 3 or the right limit plate 2. The limit rod 5 can be used as a physical barrier to prevent the object from moving beyond the predetermined range. There are threaded holes on the upper surface of the bottom plate 1 for installing bolts 6. The bolt 6 passes through the fixing plate 4 and is fixed on the bottom plate 1 through a nut 11. When it is necessary to fix an object (such as a workpiece) on the bottom plate 1, the fixing plate 4 can be placed under the object, and then the bolt 6 and the nut 11 are tightened so that the fixing plate 4 is closely attached to the bottom plate 1, thereby clamping the object. The protective groove 12 is provided to protect the nut 11 from being impacted or damaged during use. At the same time, this also makes the whole device cleaner and reduces potential safety hazards.

[0025] The above has described the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which it pertains, various changes can be made without departing from the gist of the present utility model.
