[0008] A rectangular groove, the rectangular groove is provided in the tool box body, a reciprocating rod is slidably installed in the rectangular groove, and a rectangular block is fixedly installed at the bottom of the rectangular groove and located in the reciprocating rod;

[0009] A limiting component, which is located in the box body and is used to limit the retractable rod;

[0010] Two movable grooves, the two movable grooves are symmetrically arranged in the box body, and the two movable grooves are respectively located on both sides of the rectangular groove, a sliding block is slidably installed in the movable groove, and a roller is fixedly installed at one end of the sliding block and located in the movable groove;

[0011] Two fixing components are both located in the box body and are used to fix the two sliding blocks respectively.

[0012] In the present technical solution, the limit assembly is set, and the limit assembly can release the limit of the return rod. At this time, the return rod can be pulled, and the return rod moves in the rectangular groove. The personnel can adjust the extended length of the return rod according to their height. At the same time, under the action of the rectangular block limit, it can be ensured that the return rod will not fall off the rectangular groove. When the return rod is extended to a suitable position, the limit assembly can be used to make the return rod only move inwards in the rectangular groove and cannot move outwards, ensuring that when the return rod is put into the rectangular groove, the return rod can be put out by only pushing the return rod inwards. The rod is retracted into the rectangular groove to ensure that it is convenient for personnel to adjust the extended length of the return rod. Then, through the two fixed components, the fixed components can release the sliding block and the roller, and then the roller can be pulled outward. When the roller is fully extended, the sliding block and the roller can be fixed by the fixed component to ensure that the two rollers can be retracted and extended at will, which is convenient for personnel to use. Then, the personnel can pull the return rod, and under the action of the two rollers, the entire device can be pulled to ensure that when the tool box body is heavy, it is convenient for personnel to carry it.

[0013] In the above technical solution, further, the limit assembly includes:

[0015] When the locking cam is in the locked position, the spring will push the limit block back into the locking cam, and the limit block will push the limit block back into the locking cam, so that the limit block can move inwards and outwards, ensuring that the limit block can be retracted into the rectangular groove by pushing the limit block inwards.

[0016] In the above technical solution, further, one end of the limit block is slidably connected to the box body, one end of the limit block is plugged into the limit groove, the pull rod is slidably connected to the sliding groove and the box body, and both ends of the spring are tightly welded to the limit block and the inner wall of the sliding groove respectively.

[0017] In this technical solution, it is ensured that one end of the limit block can slide normally in the box body, that one end of the limit block can be inserted into the limit groove, that the pull rod can slide normally in the sliding groove and the box body, and that the structure of spring one is stable.

[0018] In the above technical solution, further, the fixing assembly includes:

[0019] A power cavity is provided in the box body and is located above the movable groove. A blocking block is slidably installed in the power cavity. The bottom end of the blocking block passes through the bottom of the power cavity and extends into the movable groove. A spring 2 fixed to the inner wall of the power cavity is symmetrically fixed on the top of the blocking block.

[0020] When the bottom end of the blocking block is higher than the sliding block, the roller can be pulled outward, and the movement of the roller drives the sliding block to move in the moving groove. When the sliding block moves from one side of the blocking block to the other side, the roller will be fully extended. At this time, the moving blocking block is released, and under the action of the rebound force of the two springs, the two springs will squeeze the blocking block, so that the two blocking blocks will move downward. At this time, one side of the blocking block will just rest against one side of the sliding block, ensuring that the sliding block and the roller will not move in the moving groove, ensuring that the two rollers can be folded and extended at will, ensuring that it is convenient for personnel to use. Then the personnel can pull the return rod, and under the action of the two rollers, the overall device can be pulled to ensure that when the tool box body is heavy, it is convenient for personnel to carry it.

[0021] In the above technical solution, further, the lower end of the blocking block is slidably connected to the box body, and one side of the blocking block is in contact with one side of the sliding block.

[0022] In this technical solution, it is ensured that the lower end of the blocking block can slide normally in the box body, and it is ensured that the blocking block can limit the sliding block.

[0023] In the above technical solution, further, one end of the limiting block is in an inclined structure, and the cross-section of the limiting groove is in a triangular structure.

[0024] In the technical solution, it is ensured that when the reciprocating rod moves inward in the rectangular groove, a plurality of limiting grooves will squeeze the limiting block, so that one end of the limiting block is away from the limiting groove.

[0025] In the above technical solution, further, two ends of the rectangular block are respectively tightly attached to two sides of the inner wall of the spring-shaped rod.

[0026] In this technical solution, it is ensured that the rectangular block can limit the reciprocating rod.

[0027] The beneficial effects of the utility model are:

[0028] The measuring and testing tool box can release the limit of the return rod by setting a limit component. At this time, the return rod can be pulled to move in the rectangular groove. The personnel can adjust the extended length of the return rod according to their height. At the same time, under the action of the rectangular block limit, it can be ensured that the return rod will not fall off from the rectangular groove. When the return rod is extended to a suitable position, the limit component can be used to make the return rod only move inwards in the rectangular groove and cannot move outwards, ensuring that when the return rod is put into the rectangular groove, it only needs to be pushed inwards to be released. The return rod is retracted into the rectangular groove to ensure that it is convenient for personnel to adjust the extended length of the return rod. Then, through the two fixed components, the fixed components can release the sliding block and the roller, and then the roller can be pulled outward. When the roller is fully extended, the sliding block and the roller can be fixed by the fixed component to ensure that the two rollers can be retracted and extended at will, ensuring that it is convenient for personnel to use. Then, the personnel can pull the return rod, and under the action of the two rollers, the entire device can be pulled to ensure that when the box body is heavy, it is convenient for personnel to carry it.
