[0030] Embodiment 2
[0031] The guide rod assembly 1 includes a guide rod 11, a support 12, and a spherical plain bearing 13. The striker 31 is arranged on the guide rod 11. The support 12 is fixedly arranged at the bottom of the telescopic arm 4. A rotating shaft is fixedly arranged on the support 12. The spherical plain bearing 13 is sleeved on the rotating shaft, and one end of the guide rod 11 is connected to the spherical plain bearing 13. The axis of the guide rod 11 is perpendicular to the axis of the rotating shaft, so as to ensure that when the telescopic arm 4 swings driven by the elevator 5, the moving direction of the guide rod 11 is consistent with the moving direction of the elevator 5.
[0032] Preferably, the support frame assembly 2 further includes a guide plate 23. A guide hole is vertically arranged on the guide plate 23. The guide rod 11 is arranged in the guide hole, so that the moving direction of the guide rod 11 is consistent with the moving direction of the elevator 5 during the movement process. Generally, two guide plates 23 are provided. The guide rod 11 is simultaneously arranged in the guide holes of the two guide plates 23, so as to ensure the stable state of the guide rod 11 during movement. The diameter of the guide hole is slightly larger than the cross-sectional diameter of the guide rod 11, so as to facilitate the movement of the guide rod 11 in the guide hole.
[0033] Preferably, a first mounting hole 24 is arranged on the guide plate 23, and a second mounting hole 25 is arranged on the adjusting plate 22. A mounting bolt 26 passes through the first mounting hole 24 and the second mounting hole 25 at the same time and is connected with a nut to realize the installation of the guide plate 23 on the adjusting plate 22.
[0034] Generally, the first mounting hole 24 is set as an oblong hole, and the extending direction of the first mounting hole 24 is perpendicular to the axis of the guide rod 11, so as to adjust the relative position between the guide hole and the guide rod 11 to realize the stability of the relative position.
[0035] Four first mounting holes 24 are correspondingly arranged on the same guide plate 23, and the first mounting holes 24 are symmetrically arranged in pairs. The second mounting hole 25 and the first mounting hole 24 are arranged in one-to-one correspondence, so as to make the connection state of the guide plate 23 on the adjusting plate 22 stable.
[0036] A connecting rod is fixedly arranged on the spherical plain bearing 13. Threads are arranged on the connecting rod. Correspondingly, threads are arranged at the upper end of the guide rod 11. The connecting rod and the guide rod 11 are simultaneously threadedly connected with a threaded sleeve 14, and the connecting rod, the guide rod 11, and the threaded sleeve 14 are coaxially arranged, so as to realize the detachable connection between the spherical plain bearing 13 and the guide rod 11, facilitate the installation, disassembly, and replacement of the guide rod assembly 1, and be applicable to different working conditions.

The guide rod 11 can be pressed in the through hole by the locking bolt to fix the impact block 31 on the guide rod 11, so that the position of the impact block 31 on the guide rod 11 can be adjusted to suit different working conditions.
[0038] When the elevator 5 makes a descending movement, the telescopic arm 4 descends, and the guide rod 11 descends accordingly. When the set stroke is reached, the impact block 31 impacts the lower limit switch 32, and the descending movement of the elevator 5 stops. When the elevator 5 makes an ascending movement, the telescopic arm 4 ascends, and the guide rod 11 ascends accordingly. When the set stroke is reached, the impact block 31 impacts the upper limit switch 32, and the ascending movement of the elevator 5 stops.
[0039] The guide rod 11 assembly 1 adopts the spherical plain bearing 13. When the elevator 5 makes a lifting movement, the guide rod 11 can be transported in different directions along with the elevator 5, preventing the guide rod 11 from jamming with the guide plate 23. The two upper and lower limit switches 32 are installed on the adjusting plate 22. The adjusting plate 22 is designed with a waist-shaped adjusting hole 21. The limit switch 32 and the impact block 31 can be adjusted up and down according to the actual working conditions. The adjusting plate 22 is installed on the elevator 5, avoiding the poor lifting limit effect caused by the hinge structure of the upper and lower connecting parts of the elevator, and can realize the synchronous movement of the present invention and the elevator 5, thereby realizing the precise control of the action.
