A nut assembly 3 is threadedly connected in the installation channel 2. A telescopic pin 4 is slidably inserted into the installation channel 2. Thread adjustment holes 5 are provided on the circumferential surface of the telescopic pin 4. A spring 6 is arranged in the installation channel 2, and the spring 6 is located between the telescopic pin 4 and the nut assembly 3. A positioning sliding opening 7 is provided at the top end of the fixed support 1. A positioning screw 8 is slidably connected in the positioning sliding opening 7, and the positioning screw 8 passes through the positioning sliding opening 7 and is threadedly connected to the thread adjustment hole 5. One end of the telescopic pin 4 is rotatably connected to a roller bearing 9, and the roller bearing 9 is located on one side of the fixed support 1.

[0028] In this embodiment, the fixed support 1 is installed at the position where it is needed. The telescopic pin 4 is stably telescoped in the installation channel 2 through the threaded connection between the positioning screw 8 and the thread adjustment hole 5, so that the roller bearing 9 corresponds to the workpiece. By adjusting the position of the nut assembly 3 in the installation channel 2, the compression amount of the spring 6 is adjusted. The elastic force of the spring 6 acts on the telescopic pin 4, thereby adjusting the load force of the roller bearing 9 on the workpiece. The positioning screw 8 passes through the positioning sliding opening 7 and is threadedly connected to the thread adjustment hole 5, restricting the telescopic distance of the telescopic pin 4 and preventing the telescopic pin 4 from falling off the installation channel 2.

[0029] Specifically, the installation channel 2 includes a threaded groove 21 and a sliding groove 22. The threaded groove 21 and the sliding groove 22 are respectively provided at the symmetric two side ends of the fixed support 1, and the threaded groove 21 and the sliding groove 22 communicate with each other. The nut assembly 3 is threadedly connected in the sliding groove 22. The telescopic pin 4 is slidably inserted into the threaded groove 21.

Through the threaded connection with the positioning screw 8, the expansion pin 4 can be installed at different angles, changing the rotation direction of the roller bearing 9 to adapt to different usage situations.

[0035] Specifically, one end of the expansion pin 4 is riveted with a rivet 10, and the roller bearing 9 is rotatably connected to the rivet 10.

[0036] In this embodiment, the roller bearing 9 is riveted to the expansion pin 4 through the rivet 10 and rotates in contact with the workpiece at one end of the expansion pin 4.

[0037] Specifically, a plurality of mounting holes 11 are formed in the fixed support 1.

[0038] In this embodiment, the fixed support 1 is fixedly installed through a plurality of mounting holes 11, and the plurality of mounting holes 11 are used in cooperation with bolts.

[0039] Working principle: When the workpiece is moving, the fixed support 1 is installed at the required position so that the roller bearing 9 corresponds to the workpiece. By rotating the adjusting nut 31 in the sliding groove 22, the compression amount of the spring 6 is adjusted, and the locking nut 32 is rotated to lock the adjusting nut 31, so that the spring 6 remains stable after adjustment. The elastic force of the spring 6 acts on the expansion pin 4 and the nut assembly 3, changing the load force of the roller bearing 9 on the expansion pin 4 on the workpiece. When the roller plunger is applied to workpieces moving in different directions, by threadedly connecting the positioning screw 8 into the first threaded hole 51 or the second threaded hole 52, the installation angle of the expansion pin 4 is adjusted, thereby changing the rotation direction of the roller bearing 9 to adapt to workpieces moving in different directions.
