The two upright plates 2 are vertically welded to the base 1, with a spacing of 600mm between them; the two telescopic rods 3 pass parallel through the two upright plates 2, with a horizontal spacing of 400mm between them; the operating plate 4 is welded to the rear end of the telescopic rods 3; the end plate 5 is welded to the front end of the telescopic rods 3; and the arc ring 6 is welded to the end plate 5 and secured with bolts 7 (see...). Figure 1 , Figure 2 ).

[0006] The base 1 is made of 40mm thick steel plate and has the following dimensions (length). Width) 800 600mm; Vertical plate 2 is made of 14mm thick steel plate, with dimensions of (length) Width) 800 500mm; Telescopic rod 3 is made of a 40mm diameter round tube and is 2000mm long; Operating plate 4 is made of 10mm thick steel plate and its dimensions are (length) Width) 500 200mm; End plate 5 is made of 10mm thick steel plate, with dimensions (length) Width) 500 150mm; Arc ring 6 is an arc ring made of 6mm thick steel plate, with a plate width of 30mm, an arc ring diameter of 50mm, and a folded edge length of 20mm; Bolt 7 has a diameter of 8mm and a length of 50mm.

[0007] In use, the toothless saw 9 is fixed to the arc ring 6 of the telescopic bracket using bolts 7, and the saw blade of the toothless saw 9 is brought to the ground. Then, the steel bar 8 is placed on the ground facing the saw blade of the toothless saw 9. The processing size of the steel bar 8 is adjusted, and then the toothless saw 9 is started and the telescopic rod 3 is pushed to cut the steel bar 8. The extension length of the telescopic rod 3 can be adjusted at any time according to the position of the steel bar 8 to meet the cutting needs of the steel bar 8. Figure 3 , Figure 4 ).

[0008] The advantages of this utility model are that it is easy to assemble, easy to operate, simple and practical, solves the problem of cutting steel bars with a hand-held toothed saw, reduces waste, reduces personal injury, and lowers safety hazards. Attached Figure Description

[0014] Figures 1-4 This is one specific embodiment of the present invention. The present invention will be further described below with reference to the accompanying drawings.

[0015] This utility model includes a base 1, upright plates 2, telescopic rods 3, operating plates 4, end plates 5, arc rings 6, and bolts 7, which are used in combination. The two upright plates 2 are vertically welded to the base 1, with a spacing of 600mm between the upright plates 2; the two telescopic rods 3 pass parallel through the two upright plates 2, with a horizontal spacing of 400mm between the telescopic rods 3; the operating plate 4 is welded to the rear end of the telescopic rods 3; the end plate 5 is welded to the front end of the telescopic rods 3; and the arc ring 6 is welded to the end plate 5 and fastened with bolts 7.

[0016] When in use, the toothless saw 9 is fixed in the arc ring 6 of the telescopic bracket using bolts 7, and the saw blade of the toothless saw 9 is brought to the ground. Then, the steel bar 8 is placed on the ground facing the saw blade of the toothless saw 9. The processing size of the steel bar 8 is adjusted, and then the toothless saw 9 is started and the telescopic rod 3 is pushed to cut the steel bar 8. The extension length of the telescopic rod 3 can be adjusted at any time according to the position of the steel bar 8 to meet the cutting needs of the steel bar 8.

[0017] During the construction of concrete frame structures, a toothless saw telescopic support was used for rebar cutting, achieving good results.
