Detailed description of the invention
Elaborate the utility model preferred embodiment below in conjunction with accompanying drawing.
embodiment mono-:
A kind of electric drill bracing frame, with reference to Fig. 1, it comprises column 1, and described column 1 bottom is provided with hydraulic stem 2, and hydraulic stem 2 can play the effect of adjusting the high end of column.The limit portion of described column 1 top and bottom is all provided with rotating shaft 3, and brace 5 upper ends that the upper end of described column 1 is provided with chute 4 by rotating shaft 3 and both sides are connected, and the lower end of brace 5 is free end; The both sides of described chute 4 are all inlaid with slide block 6, on described slide block 6, are equipped with slide-bar 3, also comprise lower fulcrum bar 8, and the length of described lower fulcrum bar is 1/2nd to 2/3rds of upper rack posts length, can make slide block in chute, slide better.One end of described lower fulcrum bar 8 is connected with column 1 lower end by rotating shaft 3, the other end of described lower fulcrum bar 8 is connected with slide block 6 by slide-bar 7, also comprise upper rack posts 9, the lower end of described upper rack posts 9 is connected with slide block 6 by slide-bar 7, slide-bar 3 is for having the smooth shaft compared with less friction, can reduce upper rack posts 9, lower fulcrum bar 8 promotes the resistance of slide block 6 in the time of the interior motion of chute 4; / 2nd places of described upper rack posts 9 length are laterally connected with brace 5 by spring 10, and the above-mentioned position of spring can make upper rack posts, lower fulcrum bar realize better the motion in chute; The top of described upper rack posts 9 is provided with rear clip 14, and described column 1 top is fixed with slide plate 15, is provided with slide block in slide plate, and described slide block top is fixed with front clip 11; Two clips play the effect of supporting electric drill rifle body; The front of described front clip 11 is fixed with spring 16 No. two, the front end of described No. two springs 16 is fixed with dust cover 12, the cross section of described dust cover is trapezoidal, the large end of trapezoidal dust cover is hatch frame, the small end of trapezoidal dust cover is provided with the through hole that power supply drilled through, and described through hole is provided with sealing ring; The beveled end of described dust cover is provided with dust export, and described dust export lower end is provided with dust collecting sleeve 13.When use, the drill bit of electric drill rifle body front end is passed to No. two springs 16, and through the through hole on dust cover 12, can make drill bit contact and rotate with building to be holed by compressing No. two springs 16, the elastic force of spring can ensure that dust cover is close on building, so, can avoid boring the chip dust falling and splash, can play again effect between good suction.
