The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
Shown in Fig. 1-4; A kind of multipurpose safety pincers shift mechanism of the utility model; Comprise cardan shaft housing 1, lift arm component 2, the first safety tongs lifting rod 3 and the second safety tongs lifting rod 4; Said arm component 2, the first safety tongs lifting rod 3 and the second safety tongs lifting rod 4 of lifting is arranged on the cardan shaft housing 1, and the bottom of the first safety tongs lifting rod 3 is provided with safety switch 8, and cardan shaft housing 1 is connected the first curved part 5 and the second curved part 6 through the first safety tongs lifting rod 3 respectively with the second safety tongs lifting rod 4; Also be provided with torsion spring 7 on the said cardan shaft housing 1, torsion spring 7 is arranged near the right side that lifts arm component 2.
The multipurpose safety pincers shift mechanism of the utility model, the said arm component 2 that lifts is arranged on the first safety tongs lifting rod 3 and the second safety tongs lifting rod, 4 outsides.
The multipurpose safety pincers shift mechanism of the utility model, the said first curved part 5 is arranged on the left side of the first safety tongs lifting rod 3, and the second curved part 6 is arranged on the right side of the second safety tongs lifting rod 4.
Shown in Fig. 5-6, be with embodiment 1 difference: torsion spring 7 is arranged near the right side that lifts arm component 2.Saidly lift the inboard that arm component 2 is arranged on the first safety tongs lifting rod 3 and the second safety tongs lifting rod 4.The said first curved part 5 is arranged on the right side of the first safety tongs lifting rod 3, and the second curved part 6 is arranged on the left side of the second safety tongs lifting rod 4.
