The robot arm connecting column 51 is welded to the end of the plug-in column 53, wherein the cross-section of the robot arm connecting column 51 is circular in design, and a connecting piece 54 is arranged on the surface of the robot arm connecting column 51, wherein the connecting piece 54 is used to be socketed with the first external thread 42 to fix the robot arm connecting column 51 and the second connecting column 41. The mounting part 5 also includes a limiting ring 52 opened on the surface of the robot arm connecting column 51, and the limiting ring 52 can limit the rotation of the connecting piece 54 to ensure that the connecting piece 54 can rotate independently without affecting the limiting ring 52.

[0035] The connecting member 54 includes a ring 541 sleeved on the surface of the robot arm connecting column 51, the cross-section of the ring 541 is a circular ring design, and its internal diameter is slightly larger than the external diameter of the first external thread 42, and a built-in plug-in ring 544 welded to the inside of the ring 541, the built-in plug-in ring 544 and the limiting ring 52 are plugged in, the width of the built-in plug-in ring 544 is smaller than the width of the limiting ring 52, the diameter of the built-in plug-in ring 544 is smaller than the diameter of the limiting ring 52, and the built-in plug-in ring 544 rotates in a circle inside the limiting ring 52, and the connecting member 54 also includes an internal thread 542 engraved on the inside of the ring 541, the internal thread 542 and the first external thread 42 are plugged in, and bolted to fix the robot arm connecting column 51 and the second connecting column 41, and the internal thread 542 and the first external thread 42 are threadedly connected.

[0036] The limiting portion 3 includes a frame 31 plugged into the surface of the connector 2, a first plug-in slot 32 opened inside the frame 31, and a cross-section of the frame 31 and the first plug-in slot 32. The outer shell is circular in design, and the inner slot is rectangular in design. The open rectangular size of the first plug-in slot 32 is smaller than the rectangular size inside the first plug-in slot 32, which is used to limit the position of the connector 2. The limiting portion 3 also includes a tooth plate 33 engraved on the bottom of the frame 31, a second external thread 543 engraved on the surface of the collar 541, the tooth density of the tooth plate 33 is twice the tooth density of the second external thread 543, and a second limiting plate 34 fixed on one side of the tooth plate 33 at the bottom of the frame 31, that is, the second external thread 543 will rotate with the teeth of the tooth plate 33. The teeth are engaged, and due to the density difference of the teeth, the positioning speed of the frame 31 is greater than the positioning speed of the ring 541. At this time, the second limit plate 34 will continue to limit the movement of the ring 541, further tightening the tightness of the connection between the ring 541 and the second connecting column 41. The lowest point of the second limit plate 34 is lower than the highest point of the connecting piece 54, which helps to tighten the ring 541 and the frame 31. The length of the frame 31 is greater than the length of the ring 541, and the length of the frame 31 is greater than the length of the ring 541. When the ring 541 is disassembled, it will preferentially move the teeth of the tooth plate 33 away from the teeth of the second external thread 543. When the second external thread 543 is completely away from the tooth plate 33, the ring 541 is separated from the first external thread 42.

The rectangular size of the first connecting column 21 is larger than the open rectangular size of the first plug-in slot 32 and smaller than the rectangular size inside the first plug-in slot 32, so that the frame 31 and the first limit plate 22 can be moved but will not fall off, and the first connecting column 21 and the first plug-in slot 32 are plugged in.

[0038] The effect achieved by the entire third embodiment is that the plug-in column 53 is plugged into the interior of the second plug-in groove 43, at which time the internal thread 542 is connected to the first external thread 42, and the ring 541 is rotated. At this time, the ring 541 is gradually threadedly connected to the first external thread 42. At the same time, the bottom of the toothed plate 33 is meshed with the second external thread 543. When the second external thread 543 rotates, it drives the toothed plate 33 to move on the first limiting plate 22. At this time, the second limiting plate 34 will abut against the end of the ring 541 away from the first external thread 42. The tooth density is twice that of the second external thread 543. The second external thread 543 will mesh with the teeth of the tooth plate 33 when rotating. At the same time, due to the difference in tooth density, the positioning speed of the frame 31 is greater than the positioning speed of the ring 541. At this time, the second limit plate 34 will continue to limit the movement of the ring 541, further tightening the tightness of the connection between the ring 541 and the second connecting column 41. When the ring 541 and the second connecting column 41 are fixed, the second limit plate 34 will also abut the ring 541, increasing the tightness of the ring 541 and the first external thread 42.

[0039] Working principle: When in use, first insert the plug-in column 53 into the inside of the second plug-in groove 43, at this time the internal thread 542 will be connected to the first external thread 42, rotate the ring 541, at this time the ring 541 will gradually be threadedly connected with the first external thread 42, at the same time, the bottom of the tooth plate 33 will mesh with the second external thread 543, when the second external thread 543 rotates, it will drive the tooth plate 33 to move on the first limit plate 22, at this time the second limit plate 34 will abut against the end of the ring 541 away from the first external thread 42, because the tooth density of the tooth plate 33 is twice the tooth density of the second external thread 543, the second external thread 543 rotates It will mesh with the teeth of the tooth plate 33. At the same time, due to the density difference of the teeth, the positioning speed of the frame 31 is greater than the positioning speed of the collar 541. At this time, the second limit plate 34 will continue to limit the movement of the collar 541, further tightening the tightness of the connection between the collar 541 and the second connecting column 41. When the collar 541 and the second connecting column 41 are fixed, the second limit plate 34 will also abut the collar 541, increasing the tightness of the collar 541 and the first external thread 42, thereby increasing the firmness of the bucket frame 1 and the forklift mechanical arm, reducing the probability of shaking and collision between the bucket frame 1 and the mechanical arm, and extending the service life of the bucket frame 1 and the mechanical arm.
