[0017] See also Figure 1-Figure 2 The utility model provides a technical solution: a quickly adjustable bracket, comprising a movable shell 1, a bracket body 11 is movably connected to the inner side of the movable shell 1, and also comprises a cover plate 12 and a support block 21, connecting rods 13 are vertically fixedly installed on both sides of the lower surface of the cover plate 12, the bottom ends of the two groups of connecting rods 13 are respectively fixedly connected to the two sides of the upper surface of the bracket body 11, a handle 16 is fixedly connected to the middle of the upper surface of the cover plate 12, and connecting grooves 14 are penetrated on both sides of the inner wall of the top end of the movable shell 1, and the connecting rods 13 are slidably connected to the connecting grooves 14.

[0018] In this technical solution, the staff can pull the cover 12 upward via the handle 16, and can slide the connecting rod 13 and the connecting groove 14 together. During the upward movement of the cover 12, the bracket body 11 can be pulled upward to adjust the use height of the bracket body 11. The insulation resistance tester fixedly connected to the top of the bracket body 11 can be moved out of the movable shell 1 through the through groove 15.

[0019] In this embodiment, the upper ends of the inner walls on both sides of the mobile shell 1 are symmetrically provided with slide grooves 2, and the middle part of the inner wall of one side of the slide groove 2 is rotatably connected with a screw rod 22 through a bearing, and a support block 21 is placed on one end of the inner side of the slide groove 2 and is horizontally provided with a thread groove 23, the screw rod 22 is threadedly connected to the thread groove 23, the support block 21 is slidably connected to the slide groove 2, and the size of the support block 21 matches that of the slide groove 2.

[0020] In this technical solution, rotating the screw 22 can push one end of the support block 21 out of the slide slot 2 and insert it into the interior of the movable housing 1, and can further support the bracket body 11, facilitating the normal use of the insulation resistance tester above the bracket body 11.

[0021] In this embodiment, a through slot 15 is formed in the middle of the inner wall at the top of the movable housing 1, the bracket body 11 is movably connected to the through slot 15, the cover plate 12 matches the size of the through slot 15, and the movable housing 1 matches the size of the connecting rod 13.

[0022] In this technical solution, after the insulation resistance tester on the bracket body 11 is used, the screw 22 is rotated in the opposite direction to drive the support block 21 to be retracted into the slide groove 2. Further, the bracket body 11 and the insulation resistance tester can be retracted into the movable shell 1 under the action of gravity, and the through groove 15 is blocked by the cover plate 12. This can solve the problem that the existing bracket is inconvenient to store the insulation resistance tester and adjust the use position.

[0023] When a quickly adjustable bracket is used, the staff can pull the cover plate 12 upward through the handle 16, and the connecting rod 13 is slidably connected with the connecting groove 14. During the upward movement of the cover plate 12, the bracket body 11 can be pulled upward to adjust the use height of the bracket body 11. The insulation resistance tester fixedly connected above the bracket body 11 can be moved out of the mobile housing 1 through the through groove 15, and the screw 22 can be rotated to push one end of the support block 21 out of the slide groove 2 and inserted into the interior of the mobile housing 1, so as to adjust the use height of the bracket body 11. The bracket body 11 can be supported in one step, which is convenient for the normal use of the insulation resistance tester above the bracket body 11. When the insulation resistance tester above the bracket body 11 is used up, the screw rod 22 is rotated in the opposite direction to drive the support block 21 to be retracted into the slide groove 2. Further, the bracket body 11 and the insulation resistance tester can be retracted into the mobile housing 1 under the action of gravity, and the through groove 15 is blocked by the cover plate 12. This can solve the problem that the existing bracket is inconvenient to store the insulation resistance tester and adjust the use position.
