[0023] The two uprights 1 and 2 have a length of 1600 mm, a width of 50 mm, and a thickness of 30 mm; the five crossbars 4 have a length of 150 mm, a width of 10 mm, and a thickness of 10 mm.

[0024] In the present invention, each column includes a column 8 perpendicular to the ground, the column 8 is provided with a vertical strip groove 9 extending along its length direction, and both sides of the column 8 are provided with vertical side grooves 17 communicating with the vertical strip groove.

[0026] The telescopic length of the telescopic rod 16 is 200-800 mm.

[0027] Therefore, after determining the distance between the two columns 1 and 2 according to the width of the limit space 3, the length of the telescopic rod 16 is adjusted, and the telescopic rod 16 is rotated to a horizontal state, and then the other end of the telescopic rod 16 is fixed to another column 2 by a screw, so as to adapt to the distance between the two columns 1 and 2, connect and laterally support the two columns 1 and 2, and keep the two columns 1 and 2 perpendicular to the ground.

[0028] In addition, by unscrewing the screw, the other end of the telescopic rod 16 can be separated from the other column 2, and the telescopic rod 16 can be removed.

[0029] In the utility model, each cross bar 4 is provided with a transverse strip groove 10 extending forward from the rear end, and one end of each cross bar 4 passes through the outer vertical side groove 17 and the vertical strip groove 10 in sequence from the outer side of the corresponding column, and then extends to the inner vertical side groove 17, and a bolt 11 passes through the transverse strip groove 10 and the vertical strip groove 9 in sequence from the front side and extends from the rear side, and a locking nut 12 is screwed on the extended end of the bolt 11.

[0039] Next, loosen the locking nut 12 to release the lock on each cross bar 4, and move each cross bar 4 up and down or left and right, that is, the spacing between the cross bars 4 and the length of each cross bar 4 extending outward can be adjusted, thereby adjusting the height and width of the limit space 2 6 and the limit space 3 7, thereby adjusting the height and width of the limit space used for building the protruding and recessed parts of the tooth joint.
