[0030] The connecting mechanism 3 is arranged on one side of the co-driving mechanism 2, and the connecting mechanism 3 is arranged in the middle of the co-driving mechanism 2, wherein the linear driving mechanism 1 includes a sliding displacement support plate 11 for pushing and displacement, wherein the top surface of the plate surface of the sliding displacement support plate 11 is fitted with a buffer support plate 12, and a transverse sliding rail 13 is horizontally arranged in the middle of the plate surface of the buffer support plate 12, and a sliding plate 14 is linearly pushed in the middle of the track of the transverse sliding rail 13, and a sliding groove 15 matching the transverse sliding rail 13 is opened at the bottom of the plate surface of the sliding plate 14, and the plate surface of the sliding plate 14 and the sliding groove 15 are linearly displaced.

[0031] In this embodiment: an inclined rod guide column 16 is provided in an inclined linkage manner in the middle of the top end of the sliding plate 14, a concave adjustment bracket 17 is installed in the middle of the top end of the inclined rod guide column 16, a concave slot 18 is provided in the middle of the top end of the concave adjustment bracket 17, and an adjustment plate 19 is transversely provided in the middle of the slot of the concave slot 18.

[0032] The inclined rod guide column 16 and the concave adjustment bracket 17 cooperate with each other to uniformly control the sliding plate 14 to slide forward and backward around the transverse sliding rail 13.

[0033] In this embodiment: a coordination pole 191 is vertically installed at the middle of the top of the adjustment plate 19;

[0034] A guide block 192 is also provided at the top of the rod body of the coordination vertical rod 191. A circular opening 193 is opened on the top side of the guide block 192. A blocking rod 194 is provided on the top side of the circular opening 193. The blocking rod 194 is symmetrically arranged on both sides of the top of the guide block 192.

[0035] The guide block 192 and the circular opening 193 are used to control the pulling of the plate surface of the adjustment plate 19 and uniformly control the limiting position of the guide block 192 according to the pulling state of the guide block 192 .

[0036] In this embodiment, the top end of the coordination pole 191 passes through the guide block 192 and is sleeved with a connecting sleeve 195 at the end position. A trapezoidal block 196 is provided at the top end of the connecting sleeve 195 .

[0037] The guide block 192 and the specific connecting sleeve 195 cooperate with each other to limit the lifting and lowering position of the inclined rod guide column 16, and after extending backward, it serves as a control for the left and right displacement transformation of the position of the common drive support plate 21.

[0038] In this embodiment: one end of the trapezoidal block 196 is linked to an external pressure cylinder, and the co-drive mechanism 2 includes a co-drive support plate 21 arranged at the end of the transverse sliding rail 13, and the side walls of the plate surface of the co-drive support plate 21 are also respectively provided with circular positioning openings 22, and the inner side walls of the circular positioning openings 22 are provided with infrared positioning probes 23 for positioning.

[0041] By using the co-drive support plate 21 and the infrared positioning probe 23, the cylinder drive position change is detected in time when the displacement change is completed.

[0042] In this embodiment: the connection mechanism 3 reports an access base 31 set in the middle of the side wall of the cover drive support plate 21, and a sliding sleeve 32 is horizontally installed in the middle of the access base 31. The outer wall of the sliding sleeve 32 is also provided with a square block 33, and the four corners of the side wall of the square block 33 are all provided with fastening screws 34.

A buffer spring 37 is sleeved on the surface of the connecting cross bar 36.

[0045] Prepare to return the regulating cylinder to its original position.

[0046] When used specifically: Step 1: The personnel need to pull and push through one end of the coordinated oblique rod guide column 16. When the specific push is completed, the rod body of the coordinated vertical rod 191 is extended to connect the concave adjustment bracket 17 to push the concave adjustment bracket 17 forward and backward. When pushing forward and backward, in order to better limit the traction support concave adjustment bracket 17, the groove position of the coordinated vertical rod 191 and the concave slot 18 is combined to move backward toward the position of the sliding plate 14 as a guide. After the linear displacement of the track of the transverse sliding rail 13, the power of the oblique rod guide column 16 is uniformly extended and pushed and pulled, as it passes through the concave adjustment bracket 17, it will be unified in the sliding plate 14 area as a guide after passing through the concave slot 18. The sliding plate 14 is allowed to be fine-tuned directly along the area of ​​the transverse sliding rail 13. When the specific fine-tuning is completed, the rest of the transverse sliding rail 13 can be synchronously expanded and pushed linearly along the linear direction of the transverse sliding rail 13. At this time, when the sliding plate surface 14 moves to the left along the sliding displacement support plate 11, the position of the sliding plate 14 at this moment will be coordinated with the co-drive support plate 21 at this moment. The connecting cross bar 36 at this moment will further slide linearly back and forth around the position of the sliding push rod 35. At this time, based on the surface, based on the specific connecting cross bar 36, the rod body is extended and penetrated, and then it drives the end connected to the other end of the square block 33 to be combined and then uniformly replaced to the surface of the buffer spring 37 to achieve the purpose of buffering extension.
