Specifically, it is then supported from one side of slide caliper rule 31 through hasp arc rod 133, and arc spring rod 134 when detecting the restriction, can promote lug 14 to apply external force to single, because two slide caliper rule 31 transmission each other, can make two slide caliper rule 31 all receive the thrust, closely laminating more with the wall.

The rest of the structure is the same as that of embodiment 1.

The working principle of the invention is as follows, according to the general examples 1-2: when in use, the angle to be detected is determined, for example, the corner is ninety degrees, at the moment, any calliper strip 31 is manually broken to rotate, one calliper strip 31 can be broken at the same time, two calliper strips 31 can be broken, when the calliper strip 31 rotates, the anti-skid wheel 21, the transmission gear 22 and the round shaft 23 are driven to synchronously rotate, when the transmission gear 22 rotates, the other transmission gear 22 meshed with the anti-skid wheel 21 is driven to rotate, therefore, the other calliper strip 31 synchronously rotates, the round shaft 23 drives the angle meter 10 at the top to rotate to display the rotation angle, so that the observation is conveniently promoted, when the angle is adjusted to a proper angle, no external force is applied to the calliper strip 31, the calliper strip 31 can not move through the frictional force of the two anti-skid wheels 21 and the engaging force of the two transmission gears 22, one side of the calliper strip 31 is adhered to the wall surface to observe the angle by manual pressing, checking whether the wall surface has deviation, at the moment, one hand can be used for fixing the caliper bar 31, the other hand rotates the threaded bar 9, at the moment, the threaded bar 9 can move upwards and drive the linkage piece 8 to move upwards, the linkage piece 8 can drive the bar rods 41 at two ends to move upwards, when the bar rods 41 move upwards, the inclined pressing block 42, the limiting plate 61 and the straight rod 62 can move upwards synchronously, at the moment, the extrusion position of the inclined pressing block 42 on the top surface of the inclined stressed block 51 changes, the inclined stressed block 51 can translate under the pushing of the weak spring 7, the inclined stressed block 51, the measuring plate 53 and the error preventing bar 531 move synchronously, then the error preventing bar 531 contacts with the wall surface to stop moving under the blocking of the wall surface, if the wall surface coincides with the joint surface of the caliper bar 31, the error preventing bar 531 is in the same plane with the caliper bar 31 when stopped, the measuring plate 53 cannot contact with the switch 111, and a gap exists between the wall surface and the caliper bar 31, the measuring plate 53 can stretch out the inside of the caliper bar 31 and finally contact the wall surface, meanwhile, the measuring plate 53 can extrude the switch 111 due to the increase of the moving distance, the switch 111 triggers the starter 11 to control the auxiliary unit 13 to start light so as to remind people of problems, along with the upward movement of the threaded bar 9, the straight bar 62 can gradually contact the top surface of the square notch 52 and extrude the stressed inclined block 51, the measuring plate 53 is positioned in the measuring notch 33, the stressed inclined block 51 and the measuring plate 53 are fixed, at the moment, the caliper bar 31 is separated from the wall surface, slit data can be accurately recorded by observing the number of the surfaces of the error preventing bar 531 and the measuring plate 53, after completion, the threaded bar 9 is reversely rotated so that the threaded bar 9 moves downwards, the linkage piece 8 drives the bar 41 to move downwards, the bar 41 extrudes the stressed inclined block 51 through the inclined block 42, the stressed inclined block 51 moves backwards so that the weak spring 7 is compressed, the measuring plate 53 does not extrude the switch 111, the auxiliary unit 13 is also closed, and finally the inclined block 42 extrudes the stressed inclined block 51 to the original position, and simultaneously, the bottom end of the threaded bar 9 can reset the stressed block 51, and the measurement can be completed once.

It should be noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present invention may be modified or substituted without departing from the spirit and scope of the technical solution of the present invention, which is intended to be covered in the scope of the claims of the present invention.
