A hand-held type chiseling machine support for a small side wall of a tunnel is provided with a rectangular base frame 1, a rectangular top beam frame 2 and four stand columns 3, wherein the rectangular base frame 1 is fixedly connected with the four corners of the rectangular top beam frame 2 through the four stand columns 3; the front end and the rear end of the support are inverted trapezoid frames, support columns 4 are fixed on opposite corners of the inverted trapezoid frames, sliding suspension rings 5 are slidably mounted on a cross beam I2-1 on one side, adjacent to the tunnel wall, of the rectangular top beam frame 2, lifting ropes 6 are wound at the lower ends of the sliding suspension rings 5, and a hand-held roughening machine 7 is suspended at the lower ends of the lifting ropes 6. The rectangular base frame 1 and the rectangular top beam frame 2 are made of steel pipes through welding, and four corners of the rectangular base frame and four corners of the rectangular top beam frame are fixedly connected through four upright posts 3 through welding. The purpose that one person operates the hand-held roughening machine to complete roughening work is achieved.

Two ends of the outer side of the beam I2-1 are fixedly provided with travelling wheels I8 which are in contact with the tunnel wall; a traveling wheel II 9 which is in contact with the ground is fixed in the center of the inner side of the bottom of the inverted trapezoidal frame; the support is convenient to move, and the two ends of the outer side of the beam II 1-1 at one side of the rectangular base frame 1 adjacent to the tunnel wall are fixed with walking wheels III 10 in contact with the wall of the reserved ditch, so that the support is limited from moving transversely. And the travelling wheel II 9 is a travelling wheel with a brake, so that the support does not move randomly along the tunnel direction, and the chiseling working quality and safety are ensured.

The sliding suspension ring 5 is provided with a suspension arm 5-1, the upper part of the suspension arm 5-1 is connected through a bolt pin I5-2, and the lower part of the suspension arm 5-1 is connected through a bolt pin II 5-3; the bolt pin I5-2 is located above the beam I2-1, the suspension arm 5-1 is located on two sides of the beam I2-1, the bolt pin II 5-3 is located below the beam I2-1, and the suspension rope 6 is wound above the bolt pin II 5-3.
