[0024] Please see Figure 1-Figure 3 As shown, the present application provides a plug-in pin structure, including a support frame 6 and a handle assembly, the handle assembly including a first handle 1 and a first pull rod 2, one end of the first pull rod 2 is connected to the first handle 1, the first handle 1 is arranged on the outside of the support frame 6, and the interior of the support frame 6 is provided with a mounting slot, the first pull rod 2 is slidably set in the mounting slot, and the end of the first pull rod 2 away from the first handle 1 is provided with a positioning pin 11, the end of the positioning pin 11 is used to connect a tooling device, the positioning pin 11 is at least partially located in the mounting slot, the outside of the first pull rod 2 is provided with a spring 7, one end of the spring 7 abuts against the end face of the positioning pin 11, a positioning flange 3 is provided between the support frame 6 and the first handle 1, and the positioning flange 3 is provided with a positioning groove group for positioning the handle assembly. When the first pull rod 2 slides in the installation slot, it will drive the positioning pin 11 to slide together. The plug-in pin structure of the present application can position the handle assembly through the positioning slot group to achieve locking of the tooling device. The user can operate it with one hand, which is more convenient. The plug-in pin structure has a simple structure and low processing cost.

[0025] Furthermore, an external thread section is provided at the end of the first pull rod 2 away from the first handle 1, and a connecting groove is provided along the length direction of the positioning pin 11. The inner wall of the connecting groove is provided with an internal thread section, and the external thread section and the internal thread section are screwed together to connect the first pull rod 2 and the positioning pin 11.

[0026] Please also refer to Figure 4 As shown, it should be noted that the mounting slot includes a first mounting hole 4 and a second mounting hole 5 that are interconnected. The inner diameter of the first mounting hole 4 is smaller than the inner diameter of the second mounting hole 5. One end of the first pull rod 2 is located in the second mounting hole 5. The first pull rod 2 can move left and right in the first mounting hole 4 and the second mounting hole 5. The outer diameter of the spring 7 is smaller than the inner diameter of the first mounting hole 4. The outer diameter of the locating pin 11 is larger than the inner diameter of the first mounting hole 4. The locating pin 11 is slidably connected to the second mounting hole 5. The support frame 6 is provided with a first through hole 16. The first through hole 16 is connected to the first mounting hole 4. The first pull rod 2 passes through the first through hole 16. The inner diameter of the first through hole 16 is smaller than the outer diameter of the spring 7. There is a stepped surface at the connection between the first mounting hole 4 and the first through hole 16. The spring 7 cannot enter the first through hole 16. One end of the spring 7 abuts the end face of the locating pin 11, and the other end abuts the stepped surface.

[0027] Specifically, the inner wall of the connection between the first mounting hole 4 and the second mounting hole 5 is provided with a beveled surface 17. This configuration gives the connection between the first mounting hole 4 and the second mounting hole 5 a roughly trumpet-shaped shape. Because the inner diameter of the first mounting hole 4 is smaller than that of the second mounting hole 5, the provision of beveled surface 17 provides a transition and buffer for the components within the mounting slot as they move from the second mounting hole 5 to the first mounting hole 4, preventing the spring 7 from becoming stuck when entering the first mounting hole 4 from the second mounting hole 5.

[0028] Please continue to see Figure 1 and Figure 2 As shown, in one embodiment of the present disclosure, the positioning groove group includes a first positioning groove 9 and a second positioning groove 10, and the spring 7 has a released state and a compressed state. When the first handle 1 is located in the first positioning groove 9, the spring 7 is in the released state; when the first handle 1 is located in the second positioning groove 10, the spring 7 is in the compressed state. Specifically, the groove depth of the first positioning groove 9 is greater than the groove depth of the second positioning groove 10. When the first handle 1 is located in the first positioning groove 9, the length of the first pull rod 2 inserted into the mounting slot is the longest, one end of the positioning pin 11 is located outside the mounting slot, and the spring 7 is in the released state. When the first handle 1 is located in the second positioning groove 10, the length of the first pull rod 2 inserted into the mounting slot is shorter, and the length of the positioning pin 11 inserted into the second mounting hole 5 is longer. At this time, the end surface of the positioning pin 11 where the connecting groove is provided is very close to the first mounting hole 4, and the spring 7 is in the compressed state. In this way, the tooling device connected to the end of the positioning pin 11 (the end away from the connecting groove) can be positioned in the desired position. It should be noted that in the process of the first handle 1 entering the first positioning groove 9 from the second positioning groove 10, the spring 7 in a compressed state will drive the positioning pin 11 to move away from the first handle 1, so that the positioning pin 11 and the first handle 1 move under the elastic force of the spring 7, causing the first handle 1 to automatically return to the first positioning groove 9.

[0029] Furthermore, the positioning flange 3 includes a connecting plate 14 and a connecting frame 15 mounted on the connecting plate 14. The connecting plate 14 is connected to the support frame 6 via bolts, and a positioning slot group is provided on the connecting frame 15. Specifically, the first positioning slots 9 are two upper and lower slots arranged vertically on the connecting frame 15, and the second positioning slots 10 are two left and right slots arranged horizontally on the connecting frame 15, with the left and right slots located between the upper and lower slots. When the first handle 1 enters the second positioning slot 10 from the first positioning slot 9, it is necessary to pull the first handle 1 in the opposite direction of the positioning pin 11 and rotate the first handle 1 90 degrees. The first handle 1 can then enter the second positioning slot 10.

[0030] In order to further facilitate manual operation and the positioning groove group to limit the first handle 1, the first handle 1 of the present application is configured as an elliptical ring structure.

[0031] Furthermore, the support frame 6 includes a base 12 and a frame body 13 mounted on the base 12. The positioning flange 3 is connected to the frame body 13, and mounting slots are provided on the frame body 13. The provision of the base 12 provides greater stability for the support frame 6 during operation, preventing shaking during operation. To conserve material, the base 12 is provided with a material-saving hole.

[0032] To prevent the locating pin 11 from rocking up and down or left and right when sliding in the second mounting hole 5, the outer diameter of the locating pin 11 is adapted to the size of the second mounting hole 5. That is, the locating pin 11 is not suspended in the second mounting hole 5. The locating pin 11 is in contact with the inner circumferential wall of the second mounting hole 5. Therefore, when the locating pin 11 slides, friction will be generated with the inner circumferential wall of the second mounting hole 5. To make the sliding of the locating pin 11 in the second mounting hole 5 smoother, an oil filling hole 8 is opened on one side of the frame 13. The oil filling hole 8 is connected to the second mounting hole 5. Lubricating oil enters the inner circumferential wall of the second mounting hole 5 through the oil filling hole 8, making it easier for the locating pin 11 to slide under the lubrication of the lubricating oil.

[0033] The present application has been described in detail above. Specific examples have been used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is intended only to facilitate understanding of the present application and its core concepts. It should be noted that, without departing from the principles of the present application, a number of improvements and modifications may be made to the present application by a person skilled in the art, and such improvements and modifications shall fall within the scope of protection of the claims of the present application.
