When the sliding column 6 slides outward, the second motor 9 is appropriately turned on for cooperation, which effectively avoids the problem of disconnection of the pull rope 11 due to the limit of the hammer 14 by the limit column 15, thereby further enhancing the safety of operation.

[0024] A slide cylinder 19 is fixedly connected to the bottom plate 1, a rotating shaft 20 is rotatably connected to the slide cylinder 19, a handle 21 is fixedly connected to one end of the rotating shaft 20, a first bevel gear 22 is fixedly connected to the rotating shaft 20, a second bevel gear 23 is meshedly connected to the first bevel gear 22, a threaded screw rod 24 is fixedly connected to the second bevel gear 23, a slide rod 25 is threadedly connected to the threaded screw rod 24, the slide rod 25 is slidably connected in the slide cylinder 19, one end of the slide rod 25 is fixedly connected to the box body 2, a universal wheel 26 is provided at the bottom of the bottom plate 1, a handle 27 is fixedly connected to one side of the bottom plate 1, four sets of universal wheels 26 are provided, and the universal wheels 26 have a self-locking function , pulley 12 is fitted on the pull rope 11, pulley 2 13 is fitted on the pull rope 11, frame 4 is fixedly connected in the base plate 1, bracket 8 is slidably connected in the base plate 1, sliding column 6 runs through frame 4, sliding column 6 runs through box 2, when using the verticality measuring pendulum 14 for house safety appraisal, the height is quickly adjusted by manually adjusting the handle 21 and the electric adjustment slide 6, so that the position of the pendulum 14 can be quickly adjusted according to the detected house height, which greatly improves the efficiency of verticality measurement, and the self-locking function of the universal wheel 26 effectively prevents the pendulum 14 from shaking, thereby improving the accuracy of measurement.

[0025] Working principle: When using the verticality measuring hammer 14 for house safety appraisal, the staff first pushes the handle 27 to push the verticality measuring hammer 14 to the floor to be appraised through the rotation of the universal wheel 26, so as to move the verticality measuring hammer 14 according to the appraised floor. Then the staff twists the handle 21 according to the detected house height, and the handle 21 drives the rotating shaft 20 to rotate on the slide 19, and the rotating shaft 20 drives the first bevel gear 22 to rotate, and the first bevel gear 22 drives the second bevel gear 23 to rotate, and the second bevel gear 23 drives the threaded screw 24 to rotate on the slide 19, and the threaded screw 24 drives the slide 25 to slide upward in the slide 19 through the threaded connection, thereby the verticality measuring hammer 14 is moved. The hammer 14 is used to adjust the height, which is convenient for the staff to adjust according to the height measured by the floor, thereby increasing the efficiency of the verticality measurement. Then the staff turns on the first motor 3, and the first motor 3 drives the threaded screw 5 to rotate on the box body 2 and the frame 4. The threaded screw 5 drives the sliding column 6 to slide outward on the frame 4 through a threaded connection. While the sliding column 6 slides outward, the second motor 9 should be properly turned on for cooperation to prevent the pull rope 11 from being disconnected due to the limit of the hammer 14 by the limit column 15 when the sliding column 6 gradually slides outward, and the first connecting rod 7 is driven to move at the same time when the sliding column 6 slides outward, and the first connecting rod 7 drives the bracket 8 to slide upward on the bottom plate 1, and the bracket 8 slides upward while driving the second connecting rod 17 The second connecting rod 17 drives the box door 18 to rotate on the box body 2, so as to open the box body 2 and make the bracket 8 extend out of the box body 2. When the pad 16 on the sliding column 6 is in contact with the wall to be detected, the first motor 3 is turned off, and then the universal wheel 26 is locked by the self-locking function of the universal wheel 26 to prevent the pendulum 14 from shaking during the verticality detection, thereby affecting the measurement accuracy. Then the second motor 9 is turned on, and the second motor 9 drives the winding drum 10 to rotate. The pull rope 11 is loosened by the rotation of the winding drum 10, and the pendulum 14 falls downward on the pulley 12 and the pulley 2 13 by its own weight. When the pendulum 14 falls to a certain position, the second motor 9 can be turned off, and then the staff can The verticality of the distance between the hammer 14 and the wall is detected. After the detection is completed, the second motor 9 is turned on in reverse, and the second motor 9 drives the pull rope 11 on the winding drum 10 to retract the hammer 14. When the hammer 14 fits on the limit column 15, the first motor 3 is turned on in reverse, and the first motor 3 drives the sliding column 6 to slide inward on the frame 4. The sliding of the sliding column 6 drives the bracket 8 to slide downward on the bottom plate 1, thereby retracting the bracket 8. At the same time, the sliding of the bracket 8 drives the box door 18 on the second connecting rod 17 to close the box body 2. When the sliding column 6 slides to reset, the box door 18 completely closes the box body 2, thereby protecting the verticality measurement hammer 14 when not in use to prevent damage caused by long-term exposure to the outside.
