Embodiment

As Fig. 1, Fig. 2 and a kind of wide seating square shown in Figure 3, comprising: chi waist 1 and rod support 2 is characterized in that: chi waist 1 is connected with rod support 2 by bolt 3; Being processed with under bolt 3 junctions with bolt 3 centers on the chi waist 1 is the location arcuate socket 4 in the center of circle; Be processed with on the chi waist 1 and the adjusting arcuate socket 5 of locating arcuate socket 4 concentrics, and adjusting arcuate socket 5 one side inner wall surface are processed with internal tooth 6; Rod support 2 be vertical positional relationship with chi waist 1, and arcuate socket 4 places, corresponding chi waist 1 location are processed with the through hole that passes for bolt, and corresponding chi waist 1 adjusting arcuate socket 5 places are equipped with gear shaft 7; Gear shaft 7 gear end and internal tooth 6 engagements of regulating arcuate socket 5 inboards; Rod support 2 mounting teeth wheel shafts 7 places are provided be used to preventing gear shaft 7 axially movable back-up rings 8, and gear shaft 7 stretches out in back-up ring 8; Gear shaft 7 stretches out in back-up ring 8 parts and is equipped with abutment ring 9; Be equipped with disk main scale 10 on the abutment ring 9, and abutment ring 9 is provided with spring leaf 11 with disk main scale 10 contact positions; Rod support 2 outer walls are provided with the angle vernier 12 that cooperates with disk main scale 10; Gear shaft 7 stretches out in back-up ring 8 ends and is provided with rotary handle 13;

Rotary handle 13 is fixed on gear shaft 7 ends by screw, and outside surface is processed with anti-skidding screw thread, makes things convenient for the user to rotate rotary handle 13;

Regulate arcuate socket 5 inboard internal tooth 6 reference diameter 30mm, and the number of teeth is 60; Gear shaft 7 is reference diameter 5mm with internal tooth 6 meshed gears, the gear of the number of teeth 10, realized the ratio of gear of 1:6, it is 360 °/6=60 ° that rotary handle changes 1 angle value that changes, therefore disk main scale 10 has been divided into 60 equal portions, and each lattice then is 1 °, and corresponding disk main scale 10 angle values of 20 lattice that are divided on the angle vernier 12 are 19 °, each lattice actual angle value 19*60 '/20=57 ' on the angle vernier 12 then, according to each lattice on the differential principle angle vernier be expressed as 3 ';

Adopt the wide angle vernier 12 usefulness screws of the utility model of technique scheme to be fastened on the rod support 2, angle vernier 12 is fixed, disk main scale 10 is installed on the abutment ring 9, the spring leaf 11 of pretension location has been installed between disk main scale 10 and the abutment ring 9, rectangular tooth clutch by processing between abutment ring 9 and the rotary handle 13 is connected, rotary handle 13 is fastened on the gear shaft 7 by screw, namely rotates rotary handle 13 disk main scales 10 and rotates thereupon;

At first chi waist 1 is fixed as the right angle with rod support 2, because disk main scale 10 is connected with spring leaf 11 between the abutment ring 9, " 0 " scale mark that namely can adjust disk main scale 10 index dials aligns with " 0 " scale mark of angle vernier 12, this moment, wide seating square was plumbness, if the vertical situation of wide seating square changes (being that chi waist 1 changes with rod support 2 angles), relatively rotate owing to chi waist 1 this moment, impel the chi waist to adjust internal tooth 6 gear shaft 7 rotations of arcuate socket 5 inboards, namely drive 10 rotations of disk main scale, " 0 " scale mark of disk main scale 10 will separate with " 0 " scale mark of angle vernier 12 at this moment, the user can find out the deflection situation of angle intuitively like this, determines that chi waist 1 and rod support 2 non-perpendicular states need to regulate this moment;

During adjusting, the user at first unclamps the bolt that is fastened on bar hole 4 positions, location, rotate rotary handle 13 according to the wide seating square angle difference that detects, namely drive 1 rotation of chi waist by gear shaft 7, adjustment makes " 0 " scale mark of disk main scale 10 index dials align again with " 0 " scale mark of angle vernier 12, then the bolt of screwed in place bar hole 4 positions; When the angle of wide seating square during less than 90 °, clockwise rotate rotary handle 13, when angle during greater than 90 °, counterclockwise rotate rotary handle 13;

To sum up the utility model novel structure, processing easy, easy to use, improved work efficiency, improved advantage such as product precision, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art are not in breaking away from the technical solutions of the utility model scope, appeal the equivalent embodiment that the technology contents that discloses is made a little change or is modified to equivalent variations when utilizing, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
