[0024] The first embodiment, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 : a chiseling device for building construction, comprising a bottom plate 1, a hinge seat 7 arranged on the upper surface of the bottom plate 1 at the front end, a rectangular frame 3 hingedly arranged in the hinge seat 7, a chiseling motor 5 connected in the rectangular frame 3 through a straight line driving mechanism, a burr bit 6 connected with the chiseling motor 5, an angle adjusting mechanism connected with the upper part of the side wall of the rectangular frame 3, and a rear seat force bearing mechanism arranged on the rear side of the bottom plate 1. Figure 1 As shown, the burr bit is in a horizontal forward posture, at this time, under the action of the angle adjusting mechanism, it can rotate along an arc trajectory 15, the maximum angle is that the burr bit is vertically downward, within this range, when the angle adjusting mechanism stops adjusting, the burr bit is fixed at this angle, thereby enabling the burr bit of the present application to be adjusted at a large angle, and being suitable for chiseling of concrete vertical surface, horizontal surface and various angle inclined surface.

[0025] In the present embodiment, as shown in Figure 1 , four walking wheels 2 are arranged on the lower surface of the bottom plate 1, a mounting plate 11 is arranged on the rear end of the upper surface of the bottom plate 1 along the longitudinal direction, and a U-shaped handrail 12 is arranged on the top end of the mounting plate 11.

A movable seat 18 is screwed on the lead screw 17, and the two ends of the movable seat 18 are respectively slidably connected to the two opposite inner walls of the rectangular frame 3. A chiseling motor 5 is fixedly provided at the front end of the movable seat 18, and the output shaft of the chiseling motor extends forward and is connected to a chiseling drill bit 6.

[0027] In this embodiment, Figures 1-3 As shown, the angle adjustment mechanism includes a U-shaped frame 8, the two arms of which are rotatably connected to the two side walls of the rectangular frame 3.
