The second fixing assembly 50 is installed as follows: before the third measuring arm 301 is mounted to the measuring body 10, the pressing end of the pressing piece 501 passes through the mounting hole until the limit end of the pressing piece 501 abuts against the measuring body 10, so that the pressing piece 501 cannot continue to move.

Then, the user sets the pressing spring 503 between the pressing end and the limiting end of the pressing member 501, and then connects the pressing end of the pressing head 502 with the pressing head 502 by screw.

Then, after the user installs the related components of the third measuring arm 301, the user may press the pressing head 502 to drive the limiting end of the pressing rod to abut against the third measuring arm 301, so as to complete the fixing of the third measuring arm 301, and at this time, the pressing spring 503 is compressed along with the movement of the pressing head 502, and is in a compressed state.

Finally, after the user finishes reading the measured value on the third measuring arm 301, the extrusion head 502 is directly released, at this time, the extrusion head 502 rebounds under the action of the resilience force of the extrusion spring 503, and the limiting end of the extrusion rod is propped against the measuring body 10 again, so as to limit the extrusion piece 501, and avoid the extrusion piece 501 from falling out.

It should be noted that, the first fixing component 40 completes the fixing function through self-locking, and the second measuring component 30 completes fixing under the assistance of external force, so that the combination can achieve the maximization of efficiency.

Since the first measuring arm 201 and the second measuring arm 202 need not be changed after moving a required distance in actual use, the positions of the first measuring arm 201 and the second measuring arm 202 can be designed as self-locking fixing components, which is convenient for a user to measure multiple groups of automobile glass 70 and saves time for adjusting the first measuring arm 201 and the second measuring arm 202.

If the second fixing assembly 50 is designed to be self-locking, the radian information needs to be locked first every time and unlocked after the value is read, so that the third measuring arm 301 is retracted into the measuring body 10 to finish the next measurement. In the device, only external force is applied to the third measuring arm 301, the third measuring arm 301 is temporarily fixed so as to be convenient to pick up, a user directly withdraws the external force after acquiring data, the third measuring arm 301 withdraws to the original position under the action of the limiting spring 303, the user can directly perform the next measurement, the operation steps are reduced, and the measurement time is saved.

Thus, the cooperation of the two securing assemblies maximizes the efficiency of the device application.

Based on the same inventive concept, referring to fig. 12, fig. 12 illustrates a flow chart of a measurement method. The embodiment of the application provides a measuring method, which adopts the measuring device in any embodiment to measure. The measuring method comprises the following steps:

s110, determining a measuring position of the second measuring component 30 by moving the first measuring component 20 along the first direction X;

s120, placing the measuring body 10 on a detection surface of the automobile glass 70;

s130, based on the measurement position, determining the radian of the automobile glass 70 corresponding to the measurement position by moving the second measurement assembly 30 along the second direction Y.

In step S110, after the user obtains the dimensions of the automobile glass 70 and the gauge 60, and determines the position information of the radian to be measured, the distance required to move both the first measuring arm 201 and the second measuring arm 202 is obtained by calculation. Then the user pulls the first measuring arm 201 and the second measuring arm 202 to move, and in the pulling process, the measuring marks on the first measuring arm 201 and the second measuring arm 202 are observed until the required values appear, and the pulling is stopped, and the first fixing screw 401 and the second fixing screw 402 are rotated to fix the measuring marks respectively.

In this step, because the total measuring range between the first measuring arm 201 and the second measuring arm 202 can be flexibly adjusted, the user can correspondingly adjust the moving distance of the first measuring arm 201 and the second measuring arm 202 according to the automobile glass 70 with different sizes, so as to meet the requirement of measuring the radian of the automobile glass 70 with different sizes of different automobile types.

Similarly, when the user needs to measure the radian of a piece of glass at different positions by using the device, the distance moved by the first measuring arm 201 and the second measuring arm 202 can be adjusted accordingly according to the position of the required measured radian on the glass 70 of the automobile.

Specifically, when the radian of the middle position of the automobile glass 70 needs to be measured, the distances of the first measuring arm 201 and the second measuring arm 202 can be set to be equal, so that the third measuring piece can be ensured to be positioned in the middle of the automobile glass 70, and then the radian of the current position of the third measuring piece can be measured.

When the radian of other positions of the automobile glass 70 needs to be measured, the moving distance of the second measuring arm 202 can be changed under the condition that the moving distance of the first measuring arm 201 is unchanged, so that the relative positions of the third measuring arm 301 and the detecting surface of the automobile glass 70 are shifted, and the radian measurement of other positions is realized. Similarly, the moving distance of the first measuring arm 201 may be changed when the moving distance of the second measuring arm 202 is not changed. The movement distance of the first measuring arm 201 and the second measuring arm 202 may also be changed simultaneously to measure the radian of more positions on the automobile glass 70.

In step S120, the user places the device on the detection surface of the car glass 70. The user holds the device close to the detection surface of the car glass 70 until the first support 203 and the second support 204 are abutted against the contact surface of the car glass 70.

In step S130, since the bottoms of the first supporting member 203 on the first measuring arm 201, the second supporting member 204 on the second measuring arm 202, and the measuring portion of the third measuring arm 301 are flush on the horizontal plane, when the first supporting member 203 and the second supporting member 204 are abutted to the contact surface of the automobile glass 70, the third measuring arm 301 is abutted to the automobile glass 70 in advance, the display portion of the third measuring arm 301 protrudes from the top of the measuring body 10 due to the extrusion force, the protruding amount is the radian of the automobile glass 70, and then the user presses the extrusion head 502 to fix the third measuring arm 301, and then directly picks up the device to read the measurement mark of the protruding portion on the third measuring arm 301, and records the radian information of the automobile glass 70.

It will be appreciated that step S120 and step S130 occur simultaneously, and that the third measuring arm 301 can only perform an arc measurement if the user places the device on the vehicle glazing 70.
