[0024] The other end of the protective mechanism is detachably connected to the lens frame 3 via a magnetic attraction component.

[0025] In this embodiment: when in use, by closing the protective mechanism, the non-rotating end of the protective mechanism is connected to the frame 3 through the magnetic suction component, and then the frame 3 is pulled, the frame 3 drives the multi-stage telescopic rod to extend, and then the angle of the frame 3 is adjusted, and the frame 3 is inserted from the narrow gap to check whether there are cracks and other quality conditions on the surface of the building. When checking, it is necessary to ensure that there is sufficient light at the inspection position. If the light is insufficient, a flashlight can be used for fill light.

[0026] Please refer to Figure 1 and Figure 2 The protection mechanism includes a protection frame 6 rotatably connected to one end of the lens frame 3, and an acrylic plate 7 is fixedly connected to a through hole at the center of the protection frame 6 by adhesive.

[0027] In this embodiment: the protection frame 6 is rotated and closed, and the transparent and colorless acrylic plate 7 is at the front end of the mirror, thereby protecting the mirror surface.

[0028] Please refer to Figure 1 , Figure 2 The magnetic attraction component includes a magnet 8 fixedly connected to one end of the acrylic plate 7 by adhesive, the magnet 8 is located at the edge of the non-rotating end of the protection frame 6, and the magnet 8 is located at the end of the protection frame 6 away from the reflector 5. The magnetic attraction component also includes an iron column 4 connected to one end of the frame 3 by bolts, the iron column 4 protrudes outward, and the bolt passes through the back end of the frame 3 and is connected to the screw hole at the center of the iron column 4;

[0029] A post hole 10 is formed on the protection frame 6 , and the post hole 10 is aligned with the magnet 8 .

[0030] In this embodiment: when the protective frame 6 is closed, the protective frame 6 drives the magnet 8 to rotate synchronously until the protective frame 6 fits the surface of the mirror frame 3. At this time, the iron column 4 is in the column hole 10, and one end of the magnet 8 contacts one end of the iron column 4, and the two are magnetically connected;

[0031] By designing the iron column 4 to protrude outward and cooperate with the column hole 10, the following purposes can be achieved: a hollow rubber ring is fixed in the column hole 10 by glue, and the inner diameter of the rubber ring is slightly smaller than the iron column 4. Therefore, during the overlap between the iron column 4 and the column hole 10, the rubber ring is squeezed and deformed until the end of the iron column 4 contacts the magnet 8 to achieve magnetic attraction, and the deformed rubber ring can increase the friction force, further ensuring the stability of the protective frame 6 in the closed state.

[0032] Please refer to the figure in particular. The top of the outer wall of the sleeve rod 1 located at the outermost periphery is formed with an inner protrusion 11 protruding inward, the bottom of the outer wall of the sleeve rod 1 located at the innermost periphery is formed with an outer protrusion 12 protruding outward, the top ends of the outer walls of the other multiple sleeve rods 1 between the outer sleeve rod 1 and the innermost periphery sleeve rod 1 are all formed with inner protrusions 11, the bottom ends of the outer walls of the other multiple sleeve rods 1 between the outer sleeve rod 1 and the innermost periphery sleeve rod 1 are all formed with outer protrusions 12, the inner periphery of the inner protrusion 11 and the outer periphery of the outer protrusion 12 are fixedly connected with rubber pads by adhesive, the rubber pads are used to increase friction, and a holding sleeve 9 is interference fit on the outer wall of the outermost periphery sleeve rod 1.

[0033] In this embodiment: the gripping sleeve 9 can increase the friction between the outermost sleeve rod 1 and the hand, and the rubber starch gripping sleeve 9 can increase the comfort of gripping;

[0034] During the extension or shortening of the multi-stage telescopic rod, the multiple sleeve rods 1 respectively drive the inner protrusions 11 and the outer protrusions 12 to slide on the inner and outer walls of the adjacent sleeve rods 1. During the sliding process, the rubber pads move synchronously. The rubber pads are in a compressed and deformed state, which can effectively enhance the friction between the adjacent sleeve rods 1 and prevent the multi-stage telescopic rod from extending or retracting without the action of active force.
