working principle

In the present invention, the iron hammer for civil engineering has the functions of nail removal, small head hammering and large head hammering, and also has the functions of verticality detection, marking marking and gray line marking to determine the position: the nail removal work At the same time, the nailing work can be carried out through the claw hammer head 21, which is convenient to operate; the small head hammering and big head hammering functions: the small head threaded hammer head can be replaced by loosening the secondary limit bolt 26 according to the use requirements The order of use of 25 and the big threaded hammer 27 is easy to operate. When using the big threaded hammer 27 for hammering work, it is only necessary to thread the big threaded hammer 27 to the inner lower part of the hollow hammer body 24 and tighten the secondary limit bolt 26. When using the small-head threaded hammer 25 for hammering work, thread the small-headed threaded hammer 25 to the inner lower part of the hollow hammer body 24, and tighten the secondary limit bolt 26; verticality detection expansion function : take off the plug head 93 from the secondary handle pipe 8, drag out the nylon vertical line 91 and the hammer body 92, hold the hanging ring 94, the hammer body 92 will hang down naturally, and then the work of measuring verticality can be carried out, and it can also cooperate with The leveling bead 931 is used for horizontal detection, and the verticality bead 921 is used to confirm the verticality to ensure more accurate detection; the expansion function of the marking line: loosen the first-level hexagonal socket bolt 4 and the second-level hexagonal socket bolt 6, and take The lower lengthened engraving knife rod structure 3, can carry out the carving work with the stainless steel engraving knife 33, and can accurately mark the line by cooperating with the setting of the marker pen 312; cooperating with the setting of the iron absorbing piece 341, it can also carry out the adsorption and search of small objects; Determine the position by marking the gray line Expand the function: by removing the connecting rod structure 7 from between the primary handle 5 and the secondary handle 8, hold the rubber slider 716 and pull it to the left, so that the white gray line 715 is pulled from the belt There is lime powder ash tank 714 to pull out, because the white gray line 715 is contaminated with the lime powder in the lime powder ash tank 714 in the process of pulling out, now only need to pull up the white gray line 715 gently, release Rebound, the lime powder ash line falls, at this time, traces of lime powder are left on the ground, and the horizontal position can be determined, which is easy to operate. Move the folding handle 7111 to make the take-up wheel 711 rotate, and retract the white gray line 715 until the rubber slider 716 is attached to the left surface of the wheel seat 712; With a variety of functions, it is convenient to choose and use.
