There is a track slab 3 below the steel rail 4, and a base slab 2 is arranged below the track slab 3, and a graded crushed stone layer 1 is arranged below the base slab 2. The steel rail 4 is connected to the fixed box 7 through a first bolt 5. The fixed boxes 7 are symmetrically arranged about the center of the square steel 10, and C-shaped steels 9 are connected inside the fixed boxes 7, and both ends of the C-shaped steels 9 are closed. A gasket 6 is arranged at the front end of the first bolt 5, and the gasket 6 contacts the steel rail 4. The inside of the fixed box 7 is connected to the C-shaped steel 9 through a second bolt 8, and the C-shaped steel 9 is slidably connected to the square steel 10;

[0019] During use, after first laying the graded crushed stone layer 1 on the ground, lay the base slab 2 above it. At the same time, lay the track slab 3 above the base slab 2. At this time, after laying the track above the track slab 3, connect the fixed box 7 to the steel rail 4 through the first bolt 5. At the same time, place a gasket 6 at the front end of the first bolt 5 to prevent damage to the steel rail 4. At this time, after installing all the fixed boxes 7 on both sides, insert the C-shaped steel 9 into the fixed box 7 and then connect the C-shaped steel 9 and the fixed box 7 through the second bolt 8;

[0020] Through holes 11 are arranged on the surface of the square steel 10. The through holes 11 are arranged in an array on the surface of the square steel 10. Nuts 13 are symmetrically arranged about the center of the screw rod 12. The screw rod 12 is arranged inside the through hole 11, and the screw rod 12 is threadedly connected to the nut 13.

At this time, the lead screw 12 can be inserted into the through hole 11 on the surface of the square steel 10 according to requirements. Since there are multiple through holes 11, different through holes 11 can be rotated according to requirements. After the lead screw 12 is inserted, the nuts 13 on both sides are screwed to complete the fixation of the lead screw 12. After the small electric pickaxe 19 is inserted into the middle position between the fixing rings 15 on both sides, the fixing rings 15 on both sides are connected by the double-headed bolt 18. At this time, the threaded rod 16 is rotated, so that the threaded rod 16 drives the front support plate 17 to be adjusted. The small electric pickaxe 19 is fixed by the contact between the support plate 17 and the surface of the small electric pickaxe 19, and the fixation of the small electric pickaxe 19 is completed, which is convenient for subsequent use, thus completing a series of work.
