The lower positioning assembly is arranged above the bottom plate of the angle adjusting seat 6.1 and is used for transversely clamping the lower end of the fork body of the shock absorber to realize lower end positioning. The upper positioning assembly is arranged on the side plate of the angle adjusting seat 6.1 and is located above the lower positioning assembly and is used for transversely clamping the upper end of the fork body of the shock absorber to realize upper end positioning.

[0049] As shown in Figure 13 , the hinge assembly includes a first hinge seat, a second hinge seat, a first pivot shaft, a second pivot shaft, a first hinge lug, and a second hinge lug. The first hinge seat and the second hinge seat are arranged on the left and right sides of the tool base plate 6.2. The first hinge lug and the second hinge lug are arranged on the left and right sides of the bottom surface of the angle adjustment seat 6.1. The first hinge seat and the first hinge lug are hingedly connected by the first pivot shaft. The second hinge seat and the second hinge lug are hingedly connected by the second pivot shaft. The structure of the hinge assembly is a conventional hinge structure, which can be realized by those skilled in the art. In this embodiment, in order to facilitate outward flipping, the hinge assembly is arranged on the outside of the locking assembly (i.e., the hinge assembly is in front and the locking assembly is behind, avoiding interference when flipping outward).

[0050] As shown in Figure 13 , the locking assembly includes a first locking cylinder 6.5, a second locking cylinder 6.6, a first locking lug seat 6.7, and a second locking lug seat 6.8. The first locking cylinder 6.5 and the second locking cylinder 6.6 are arranged opposite to each other on the tool base plate 6.2 below the angle adjustment seat 6.1. The first locking lug seat 6.7 and the second locking lug seat 6.8 are arranged in parallel on the bottom surface of the angle adjustment seat 6.1. The first locking lug seat 6.7 and the second locking lug seat 6.8 are each provided with a locking hole. When the angle adjustment seat 6.1 is erected, the push rod of the first locking cylinder 6.5 is directly opposite the locking hole on the first locking lug seat 6.7, and the push rod of the first locking cylinder 6.5 can be inserted into the locking hole. The push rod of the second locking cylinder 6.6 is directly opposite the locking hole on the second locking lug seat 6.8, and the push rod of the second locking cylinder 6.6 can be inserted into the locking hole.

[0051] When the flipping tool 6 needs to be tilted, the push rods of the first locking cylinder 6.5 and the second locking cylinder 6.6 are retracted and withdrawn from the locking holes, respectively, and separated from the first locking lug seat 6.7 and the second locking lug seat 6.8. Then, the first flipping cylinder 6.3 and the second flipping cylinder 6.4 act to drive the angle adjustment seat 6.1 to flip outward. The bottom of the angle adjustment seat 6.1 rotates around the first pivot shaft and the second pivot shaft. The travel of the first flipping cylinder 6.3 and the second flipping cylinder 6.4 controls the angle of the outward flipping of the angle adjustment seat 6.1. When the product is placed, the first flipping cylinder 6.3 and the second flipping cylinder 6.4 act in reverse to drive the angle adjustment seat 6.1 to flip outward until the angle adjustment seat 6.1 is in a vertical state. At this time, the push rods of the first locking cylinder 6.5 and the second locking cylinder 6.6 are each directly opposite the locking hole. The push rods of the first locking cylinder 6.5 and the second locking cylinder 6.6 are inserted into the corresponding lug seat locking holes, thereby locking the position of the angle adjustment seat 6.1 and preventing it from swinging forward and backward.

The first clamping block 6.11 is connected to the push rod of the first clamping cylinder 6.9, and the second clamping block 6.12 is connected to the push rod of the second clamping cylinder 6.10. The third clamping block 6.13 is arranged between the first clamping block 6.11 and the second clamping block 6.12 and is fixedly connected to the angle adjusting seat 6.1. The left and right sides of the third clamping block 6.13 respectively form two clamping cavities with the first clamping block 6.11 and the second clamping block 6.12, and the two clamping cavities correspond to the lower end of the fork body of the shock absorber.

[0053] The fork body of the shock absorber is not a symmetrical structure, and the lower end of the fork body has a certain inclination angle with the axis. Therefore, the central axes of the components of the lower positioning assembly are not parallel to the flip axis, but have a certain angle, that is, the components of the lower positioning assembly are inclinedly arranged on the bottom plate of the angle adjusting seat 6.1.

[0054] As shown in FIG. 6, the lower positioning assembly includes a first clamping cylinder 6.9, a second clamping cylinder 6.10, a first clamping block 6.11, a second clamping block 6.12, and a third clamping block 6.13. The first clamping cylinder 6.9 and the second clamping cylinder 6.10 are oppositely arranged on the upper surface of the bottom plate of the angle adjusting seat 6.1. The first clamping block 6.11 is connected to the push rod of the first clamping cylinder 6.9, and the second clamping block 6.12 is connected to the push rod of the second clamping cylinder 6.10. The third clamping block 6.13 is arranged between the first clamping block 6.11 and the second clamping block 6.12 and is fixedly connected to the angle adjusting seat 6.1. The left and right sides of the third clamping block 6.13 respectively form two clamping cavities with the first clamping block 6.11 and the second clamping block 6.12, and the two clamping cavities correspond to the lower end of the fork body of the shock absorber. Figure 11As shown, the upper positioning assembly comprises a height adjusting plate 6.20, a U-shaped support seat 6.14, a first roller seat 6.25 and a second roller seat 6.26. The height adjusting plate 6.20 is in a long strip structure, is fixedly connected to the side plate of the angle adjusting seat 6.1, and is uniformly provided with positioning grooves in the vertical direction.
