Embodiment 1
[0038] Such as Figure 1 to Figure 4 As shown, an auxiliary device for industrial design provided by the embodiment of the present invention includes a main body and a locking device:
[0039] Wherein, the body includes a first chisel bar 10 and a second chisel bar 11, such as figure 1 As shown, both the first chisel bar 10 and the second chisel bar 11 are rod-shaped structures, wherein the upper end of the first chisel bar 10 extends to one side to form an L-shaped structure, and the two together constitute the gripping rod of the chisel engraving device. Two chisel rods 11 can be slidably arranged on the first chisel rod 10 up and down, as Figure 5 As shown, the side of the second chisel bar 11 facing the first chisel bar 10 is arc-shaped convex, the side of the first chisel bar 10 facing the second chisel bar 11 is arc-shaped concave, and the arc-shaped convex and arc-shaped concave In cooperation, the first working part 101 of the first chisel rod 10 and the second work...
Embodiment 2
[0050] In the first embodiment, only the switching of the conical chisel and the arc chisel can be realized, but in actual use, generally a long chisel is needed, so on the basis of the first embodiment, as Figure 6 to Figure 7 As shown, this embodiment also includes an extension, which includes a first extension block 30 and a second extension block 31, the first extension block 30 is hinged to the first chisel rod 10, and the second extension block 31 is hinged to the second chisel rod 11 ; The first expansion block 30 is provided with a first pressing surface matched with the first inclined surface, and the second expansion block 31 is provided with a second pressing surface matched with the second inclined surface;
[0051] The first expansion block 30 and the second expansion block 31 have at least a first working state and a second working state:
[0052] When in the first working state, the first inclined plane coincides with the first pressing surface, the second incl...
Embodiment 3
[0055] Because in the process of chiseling, for materials with thinner, better ductility and softer texture, the impact force of the hammer body is small when it is struck, but when the material is thicker and harder in texture, the impact force of the hammer body is relatively small. The impact force often needs to be relatively large, and the relatively large impact force will be directly transmitted to the operator's hands through the first grip bar and the second grip bar. In order to keep the positions of the first chisel bar 10 and the second chisel bar 11 stable , the operator needs to hold the first chisel bar 10 and the second chisel bar 11 tightly with his hands, long-term operation will cause numbness and weakness of the hands, thereby reducing the accuracy, so in this embodiment, the expanded The part also includes a first slider and a second slider, the first chisel rod 10 and the second chisel rod 11 are provided with slide grooves 113, the first slider and the se...
