When the earthquake-measuring device is used, the seismograph is placed on a horizontally static ground, the seismograph can be used for placing slideways in pairs according to the number of the azimuths to be measured and arranging a vibration-measuring mechanism matched with the number of the slideways, the slideways are in press fit with a last-stage lever and enable the slideways to point to the azimuths to be measured, when no earthquake occurs and the seismograph is static, the hanging parts apply pressure to the stress-applying levers, the pressure applied to the stress-applying levers is respectively transmitted to a connecting lever I and a tail-end lever II which are in contact with the stress-applying levers, the connecting lever I transmits the pressure to the ground disc extending frame and the weight disc, the ground disc extending frame supports the connecting lever I, because the vibration-measuring mechanism is symmetrically arranged, the force applied to the weight discs by the other hanging parts is equal in magnitude and opposite in direction, the weight discs are kept in stress balance, the weight discs further support the connecting lever I, the pressure applied to the tail-end lever II is respectively transmitted to the weight disc and transmitted to the supporting lever through the amplifying lever group II, the support lever transmits force to the last-stage lever and supports the last-stage lever to form a fulcrum of the last-stage lever, a balance weight is arranged on the last-stage lever and generates downward oblique force on the last-stage lever through gravity, the top end of the last-stage lever provides pressure towards the center direction for a slide way 14 on the position indicating mechanism, the position indicating mechanism can use the technical scheme of the indicating mechanism arranged on the existing indicating column support disclosed by the prior patent No. 2011202295790, the indicating column support is arranged on a floor, the slide way is hinged, the position close to the center is a hinged position, the mass of the end part of the slide way far away from the center is larger than that of the other end, the slide way does not fall and turn over due to the blocking of the last-stage lever, one component of the force applied to the last-stage lever by the slide way is a horizontal component towards the outer direction of a shell, a sphere I is clamped between the last-stage lever I and a connecting lever I or the sphere I is clamped between the last-stage lever I and the connecting lever I Between II, when the sphere I is clamped between the tail end lever I and the connecting lever I, because the force received on the connecting lever I is offset through the weight plate and the floor extension frame, the connecting lever I does not apply pressure on the sphere I, only the tail end lever I applies pressure on the sphere I, the reaction force generated on the sphere I in the central direction of the shell is transmitted to the tail end lever through the amplifying lever group I, when the sphere I is clamped between the tail end lever I and the connecting lever II, because the force received on the connecting lever I is offset through the weight plate and the floor extension frame, the connecting lever II is only hung on the connecting lever I, therefore, the connecting lever II does not apply pressure on the sphere I, only the tail end lever I applies pressure on the sphere I at the moment, the reaction force generated on the ball I in the center direction of the shell is transmitted to the last-stage lever through the amplifying lever group I, the horizontal component force of the counterweight, which generates a downward force on the last-stage lever through gravity, in the center direction of the shell and the horizontal force of the support lever in the center direction of the shell are mutually superposed to jointly offset the horizontal component force, which is applied to the last-stage lever by the slide way in the outer direction of the shell, the last-stage lever forms balanced extrusion fit on the slide way to ensure that the slide way is in a horizontal state in a static state, meanwhile, the ball I is also in a clamping state, and because the vibration measuring mechanism is symmetrically arranged, the force applied to the weight plate by the other symmetrically arranged pendant group is equal in magnitude and opposite in direction, so that the weight plate keeps stress balance, and further the weight plate abuts against the last-stage lever II.

When an earthquake occurs, the specific embodiment is described with reference to fig. 1-2, when the earthquake occurs, an initial motion P wave is firstly transmitted to the casing of the seismograph, so that the casing of the seismograph generates a micro displacement in the left direction which can not be observed by naked eyes, the ground disc connected with the casing moves in the left direction along with the casing, the weight disc is connected with the suspension pendulum mechanism, when the earthquake occurs, the time for transmitting the ground motion displacement to the weight disc is delayed, when the casing moves instantaneously, the weight disc does not move, the casing drives the ground disc and the ground disc connecting frame to move in the left direction, when the ground disc connecting frame moves in the left direction, the ground disc connecting frame does not abut against the connecting lever i of the right-side seismograph, at the moment, the contact position of the connecting lever i and the weight disc support i becomes a tilting point, the lower end part of the connecting lever i moves in the left direction, the upper end part moves in the right direction, so that the whole connecting lever i tilts, meanwhile, the stress application lever applies pressure to the connecting lever I at the contact part of the connecting lever I to push the lower part of the connecting lever I to incline towards the center direction of the shell more quickly, the upper end part of the connecting lever I inclines to apply pressure to the ball II, the ball II transmits the pressure to the upper end part of the stress application lever to enable the stress application lever to incline at the same angle as the connecting lever I, the stress application lever is not in contact with the head end lever II any more and does not generate pressure to the head end lever II any more, namely the support lever does not apply horizontal force towards the center direction of the shell to the final end lever any more, but the support lever also generates support action to the final end lever, meanwhile, when the ground disc connecting frame moves leftwards, the ground disc connecting frame applies pressure to the contact part of the amplifying lever group I and the ground disc connecting frame, and when the ball I is clamped between the tail end lever I and the connecting lever I, the amplifying lever group I applies force towards the right direction to the lower end part of the connecting lever I, when the sphere I is clamped between the tail end lever I and the connecting lever II, the amplifying lever group I applies a force in the right direction to the lower end part of the connecting lever II, when the sphere I is in a static state, a horizontal force in the shell center direction, which is generated by a counterweight on the final-stage lever through gravity, and a horizontal force in the shell center direction by the support lever are superposed with each other to jointly counteract a horizontal component force in the shell outer direction applied to the final-stage lever by the slide way, at the moment, the bottom part of the support lever is contacted with the ground disc extension frame to form a lower supporting point of the final-stage lever, the top part of the support lever serves as a fulcrum of the final-stage lever, a horizontal component force in the shell center direction applied to the support lever by the amplifying lever group II is counteracted by a horizontal component force in the shell outer direction applied to the final-stage lever by the slide way, so that the support lever is in a vertical balanced state, and when an earthquake occurs, the support lever does not receive a pressure applied by the amplifying lever group II any more, the upper end of the supporting lever does not apply horizontal force to the last lever in the direction of the shell, the horizontal component force of the slide rail applied to the last lever in the direction of the outer part of the shell is larger than the horizontal force of the balance weight generating oblique downward force to the last lever in the direction of the center of the shell, at the moment, the contact part of the last lever and the slide rail moves in the direction of the outer part of the shell, the bottom of the supporting lever contacts with the floor extension frame to form the lower supporting point of the last lever, the top of the supporting lever becomes the supporting point of the last lever, the supporting lever does not receive pressure applied by the amplifying lever group II, the bottom of the supporting lever moves along with the floor extension frame, the top of the supporting lever moves towards the outer part of the shell together with the last lever, the supporting lever generates oblique reversal, at the moment, the bottom of the lever moves towards the center of the shell, and the upper part of the last lever moves towards the outer part of the shell, the top of the supporting lever and the last lever move towards the outer direction of the shell together, the horizontal displacement distance at the top of the last lever is far greater than the distance of the bottom of the last lever moving towards the center of the shell, when the ground is influenced by an earthquake to move slightly, the displacement distance at the top of the last lever is far greater than the displacement of the ground from the top of the last lever, and the displacement direction at the top of the last lever is opposite to the displacement direction of the ground, the slide way overturns, and the direction of the slide way overturning is the earthquake source position of the earthquake.

Because the vibration measuring mechanisms are symmetrically arranged, when the ground disc moves leftwards, the vibration measuring mechanism on the left side is specifically analyzed, the ground disc moves leftwards, the ground disc connecting frame is not in contact with the amplifying lever group I any more, a gap is generated, the connecting lever I of the mechanism moves leftwards, and when the sphere I is clamped between the tail end lever I and the connecting lever I, the sphere I on the left side falls off; when the sphere I is clamped between the tail end lever I and the connecting lever II, the first step of the ground plate connecting frame moves leftwards to ensure that the amplifying lever group and the ground plate connecting frame are not contacted any more, the direction indicating mechanism is connected with the ground plate and slightly moves leftwards along with the ground plate, the left side slideway can push the upper end of the last level lever to slightly move leftwards, the lower end of the last level lever can move rightwards, the second step of the ground plate extending frame pushes the connecting lever I to move leftwards, the connecting lever I drives the connecting lever II to move leftwards, the last level lever drives the amplifying lever group I to move rightwards, the third step is that when in non-earthquake, the amplifying lever group I applies thrust in the leftward direction to the small sphere I and transmits the thrust to the lower end of the connecting lever II, the force is converted in direction and transmitted to the upper end of the connecting lever II according to the lever principle, the upper end of the connecting lever II is abutted against the amplifying lever group I contacted with the connecting lever group I, the balance state of the connecting lever II is kept, after the last lever drives the amplifying lever group I to move rightwards, the amplifying lever group is not contacted with the connecting lever II any more, the upper end part of the connecting lever II moves towards the amplifying lever group I, the length of the upper end part of the connecting lever group is smaller than that of the lower end part, the horizontal moving speed of the lower end part is larger than that of the upper end part, the separating time of the connecting lever II and the ball body I can be shortened, in the fourth step, the last lever drives the amplifying lever group I to move rightwards, the floor extension frame moves leftwards, the first end lever I transmits force to the tail end lever I, the lower end of the tail end lever I moves towards the direction far away from the ball body I, the ball body I is loosened, the ball body I falls off, the separating time of the connecting lever II and the ball body I can be shortened by arranging the connecting lever II, the accuracy of the earthquake measuring mechanism is improved more rapidly, the orientation of the seismic source can also be determined by the sphere I on the left side in the mode, namely the falling symmetrical direction of the sphere I on the left side is the orientation of the seismic source.
