[0031] Please see Figure 1-8 One embodiment of this utility model is: a multi-directional adjustable track fastener fastening device, including a base plate 1, a fixing mechanism 2 provided on the base plate 1, and a steel rail 4 provided on the fixing mechanism 2;

[0032] The fixing mechanism 2 includes an adjusting seat 201 and a buckle plate 202. A threaded post 203 is welded onto the adjusting seat 201, and the buckle plate 202 is mounted on the threaded post 203. A fixing block 211 is fixedly connected to the base plate 1, and a bolt 210 is threaded onto the fixing block 211. One end of the bolt 210 is rotatably connected to the adjusting seat 201 via a bearing 208. An adjusting hole 207 is provided on the adjusting seat 201. By rotating the bolt 210, the operator can push the adjusting seat 201 along the limiting guide groove 7, thereby moving the buckle plate 202 to the rail. Above the lower edge of the 4th section, the anchor bolt 6 is rotated to fix the adjusting seat 201. At the same time, the base plate 1 is fixed to the base on the ground under the action of the anchor bolt 6. The horizontal position of the adjusting seat 201 and the buckle plate 202 can be adjusted for rails 4 of different widths. Then, the nut 205 is rotated to descend along the threaded post 203, and the first spring 204 presses the buckle plate 202 onto the rail 4. The position and height of the buckle plate 202 can be adjusted to ensure that the buckle plate 202 and the rail 4 are more compact, so that the rail 4 is fixed more stably and firmly.

[0033] The bottom of the buckle plate 202 is fixedly connected to a limit post 206. The adjusting seat 201 has a limit hole 213, which is inserted into the limit post 206. A first spring 204 is sleeved on the threaded post 203, and a nut 205 is threadedly connected to the threaded post 203.

[0034] The fixing block 211 has an internal threaded hole 212. The bolt 210 is threaded into the internal threaded hole 212. The bolt 210 is fitted with a second spring 209. The position of the adjusting seat 201 can be adjusted left and right by rotating the bolt 210.

[0035] One end of the second spring 209 abuts against the fixing block 211, and the other end of the second spring 209 abuts against the bolt 210. The second spring 209 can prevent the bolt 210 from loosening due to vibration or thermal expansion and contraction.

[0036] The buckle plate 202 has a through hole 214, and the threaded post 203 passes through the inside of the through hole 214. The lower end of the first spring 204 abuts against the buckle plate 202, and the upper end of the first spring 204 abuts against the bottom of the nut 205. The setting of the first spring 204 can prevent the nut 205 from loosening due to vibration or thermal expansion and contraction.

[0037] The base plate 1 has a fastening hole 5, and an anchor bolt 6 is inserted into the fastening hole 5. The anchor bolt 6 passes through the interior of the adjustment hole 207. The position of the base plate 1 and the adjustment seat 201 can be fixed by setting the anchor bolt 6.

[0038] A limiting guide groove 7 is provided on the base plate 1. A limiting guide block 8 is slidably connected inside the limiting guide groove 7. The limiting guide block 8 is fixedly connected to the bottom of the adjusting seat 201. The rail 4 is placed on the two adjusting seats 201. The limiting guide groove 7 and the limiting guide block 8 can limit the adjusting seat 201 and prevent the adjusting seat 201 from falling off the base plate 1.

[0039] Working principle: By rotating bolt 210, the operator pushes the adjusting seat 201 along the limiting guide groove 7, causing the buckle plate 202 to move above the lower edge of the rail 4. Then, the anchor bolt 6 is rotated to fix the adjusting seat 201 in place. At the same time, the base plate 1 is fixed to the ground base under the action of the anchor bolt 6. The horizontal position of the adjusting seat 201 and the buckle plate 202 can be adjusted for rails 4 of different widths. Then, the nut 205 is rotated to descend along the threaded post 203, and with the help of the first spring 204, the buckle plate 202 is pressed onto the rail 4. The position and height of the buckle plate 202 can be adjusted to ensure a tighter fit between the buckle plate 202 and the rail 4, making the rail 4 more stable and secure.

[0040] Please see Figure 1-8 Based on the above embodiments, in another embodiment of the present invention, a protective mechanism 3 is provided on the buckle plate 202. The protective mechanism 3 includes a rubber sheet 301, and a positioning post 302 is fixedly connected to the rubber sheet 301.
