[0031] It should be noted that the first grasping member 2 and the second grasping member 3 are both rotatably connected to the fixed frame 1, and a spring 4 is provided between the first grasping member 2 and the second grasping member 3. Since the first grasping member 2 and the second grasping member 3 have a grasping function, a grasping mechanism is provided, which is convenient for quickly taking and placing the processing jig, and the target grasping object is placed in the processing jig.

[0032] like Figure 1-6 As shown, the number of the first grabbing members 2 and the number of the second grabbing members 3 are both set to two, a first connecting plate 7 fixedly connected between the two first grabbing members 2 is provided, and a second connecting plate 8 fixedly connected between the two second grabbing members 3 is provided.

[0033] like Figure 1 and Figure 4 As shown, a first connecting rod 9 and a second connecting rod 10 are sequentially provided on the fixing frame 1 , the first grabbing member 2 is rotatably connected to the first connecting rod 9 , and the second grabbing member 3 is rotatably connected to the second connecting rod 10 .

[0034] like Figure 1 As shown, one end of the spring 4 is connected to the middle of the first grabbing member 2 , and the other end of the spring 4 is connected to the middle of the second grabbing member 3 .

[0035] like Figure 4 As shown, a hinge rod 11 is provided on the fixing frame 1, and the first grabbing member 2 and the second grabbing member 3 are both rotatably connected to the hinge rod 11, and the first grabbing member 2 and the second grabbing member 3 are cross-arranged.

[0036] like Figure 1 and Figure 4 As shown, one end of the spring 4 is connected to one end of the first grabbing member 2 , and the other end of the spring 4 is connected to one end of the second grabbing member 3 .

[0037] like Figure 1 and Figure 4As shown, the fixing frame 1 is provided with a first limiting groove 12 and a second limiting groove 13 in sequence, wherein the first limiting groove 12 is used to limit the movement of the first grabbing member 2, and the second limiting groove 13 is used to limit the movement of the second grabbing member 3. In the specific implementation process, one end of the first grabbing member 2 passes through the first limiting groove 12, and one end of the second grabbing member 3 passes through the second limiting groove 13.

[0038] It should be noted that, in a gripping mechanism disclosed in this embodiment, the first limiting rod 5 and the second limiting rod 6 can be replaced by the first limiting groove 12 and the second limiting groove 13 respectively. Through the limiting effect of the first limiting groove 12 and the second limiting groove 13, it is convenient to limit the movement of the first gripping member 2 and the second gripping member 3, and realize the gripping operation of the first gripping member 2 and the second gripping member 3.

[0039] like Figure 1-6 As shown, the first grabbing member 2 is provided with a first hook 14 and a first inclined block 15 which are arranged opposite to each other, and the second grabbing member 3 is provided with a second hook 16 and a second inclined block 17 which are arranged opposite to each other. In the specific implementation process, the first grabbing member 2, the first hook 14 and the first inclined block 15 are an integrally formed structure, and the second grabbing member 3, the second hook 16 and the second inclined block 17 are an integrally formed structure.

[0042] like Figure 7 As shown, by connecting a power rod to the fixed frame 1, the power rod drives the fixed frame 1 to move downward, and the first inclined surface 20 and the second inclined surface 21 respectively contact with the processing jig. When the power rod drives the fixed frame 1 to continue to move downward, the first hook 14 and the second hook 16 are respectively connected and fixed with the processing jig to achieve the grasping of the processing jig. By connecting a power rod to the fixed frame 1, the power rod drives the fixed frame 1 to move upward and downward, and the external rod contacts with the first inclined block 15 and the second inclined block 17 respectively, driving the first hook 14 and the second hook 16 to move, so that the first hook 14 and the second hook 16 are respectively separated from the processing jig to achieve the placement of the processing jig.

[0043] Working principle: The first grabbing member 2 and the second grabbing member 3 are both rotatably connected to the fixed frame 1, and a spring 4 is provided between the first grabbing member 2 and the second grabbing member 3.
