The fastening plates 4 can press the rail 3, and fastening bolts 5 are installed on the fastening plates 4. The fastening bolts 5 fix the fastening plates 4 on the base plate 1, so as to fix the rail 3, and connecting holes 6 are opened on the walls around the top of the fastening bolts 5. The connecting holes 6 facilitate the limiting shaft 701 to limit the fastening bolts 5. The base plate 1 is provided with limiting components 7 corresponding to the fastening bolts 5. The limiting components 7 include limiting shafts 701 corresponding to the connecting holes 6. The positioning shaft 701 can limit the fastening bolt 5. One end of the limiting shaft 701 is rotatably connected to the shaft seat 702. The shaft seat 702 facilitates the rotation of the connecting rod 703, thereby preventing the limiting shaft 701 from affecting the installation of the fastening bolt 5. A connecting rod 703 is fixed on the outside of the shaft seat 702. The connecting rod 703 can connect the shaft seat 702 and the shaft sleeve 704. A shaft sleeve 704 is fixed on the end of the connecting rod 703 corresponding to the shaft seat 702. The shaft sleeve 704 can move along the guide column 10, and a reset spring 705 is installed on the outside of the shaft sleeve 704. The reaction force of the reset spring 705 can drive the connecting rod 703 and the limiting shaft 701 to move.

[0023] like Figure 1-Figure 2 As shown, a pull rod 8 is installed on the side of the connecting rod 703 opposite to the shaft sleeve 704 and the shaft seat 702, and the pull rod 8 is located in the middle of the connecting rod 703, which is convenient for the staff to use the pull rod 8 to pull the connecting rod 703 to move.

[0024] like Figure 1-Figure 3 As shown, a hollow groove 9 is opened on the bottom plate 1, and a guide column 10 is fixed in the middle of the hollow groove 9. The shaft sleeve 704 is slidably connected to the guide column 10, so that the shaft sleeve 704 can move horizontally along the guide column 10 in the hollow groove 9.

[0025] like Figure 1-Figure 2 As shown, one end of the return spring 705 is fixedly connected to the connecting rod 703, and the other end of the return spring 705 is fixedly connected to the inner wall of the slot 9, so as to facilitate fixing the return spring 705.

[0026] like Figure 1 and Figure 3 As shown, a mounting groove 2 for carrying the rail 3 is provided on the bottom plate 1 , so that the rail 3 can be connected to the bottom plate 1 through the mounting groove 2 .

[0027] like Figure 1 and Figure 3 As shown, leveling holes 11 are symmetrically provided at the four corners of the top of the base plate 1 , and threaded grooves are provided in the leveling holes 11 , so that the staff can use leveling bolts to level the installation of the base plate 1 through the adjustment holes.

[0028] like Figure 1 and Figure 3As shown, a pre-embedded hole 13 is symmetrically opened in the middle of the bottom plate 1, and a threaded groove is opened in the pre-embedded hole 13. The staff can use bolts to fix the bottom plate 1 on the embedded part through the pre-embedded hole 13.

[0029] like Figure 1 and Figure 3 As shown, two groups of fastening holes 12 are symmetrically opened on the base plate 1 on both sides of the embedded hole 13, and each group of fastening holes 12 has two fastening holes. The fastening holes 12 correspond to the positions of the fastening bolts 5, which facilitates the fastening bolts 5 to be installed into the fastening holes 12 to fix the fastening plate 4.

[0030] Working principle of the device: When the device is used, the staff can use bolts to fix the base plate 1 on the embedded parts through the embedded holes 13, and then use the leveling bolts to level the installation of the base plate 1 through the adjustment holes. After the leveling is completed, the two rails 3 to be connected are placed in the installation grooves 2 on the base plate 1 respectively. After the placement is completed, the fastening plate 4 is placed on the rails 3 and the base plate 1. The staff uses the fastening bolts 5 to install and fix the fastening plate 4 through the fastening holes 12, and fixes the rails 3 through the fastening plate 4. After the fastening bolts 5 are installed, The staff uses the pull rod 8 to pull the connecting rod 703, and the connecting rod 703 drives the sleeve 704 to move along the guide column 10 in the empty slot 9, while stretching the reset spring 705, and the staff can turn the limiting shaft 701 to rotate it along the shaft seat 702 to a position concentric with the connecting hole 6 on the fastening bolt 5. At this time, the staff loosens the connecting rod 703 and inserts the limiting shaft 701 into the connecting hole 6 through the reaction force of the reset spring 705, and limits the fastening bolt 5 through the limiting shaft 701 to prevent the fastening bolt 5 from loosening due to vibration, thereby preventing safety hazards.

[0031] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
