[0026] Please refer to Figures 1-3 The utility model provides a kind of technical solutions: the resistance value adjusting structure of load test box, it includes: control host computer 1 and wiring 4, control host computer 1 is equipped with display control panel 2 on the front, control host computer 1 is equipped with scroll wheel 3 on the bottom, wiring 4 is connected on the side of control host computer 1;

[0027] Control host computer 1 is equipped with operation table 5 on the front, operation table 5 is equipped with guide rail 6 on the bottom, guide rail 6 is equipped with sliding block 7 on one side, two groups of sliding block 7 are equipped with storage box 8 between, the bottom of sliding block 7 is equipped with fixed block 9, movable block 10 is sleeved on the outside of fixed block 9, clamping block 11 is installed on the inner wall of movable block 10, top rod 12 is connected on the side of movable block 10 and penetrates guide rail 6, connecting rod 13 is connected between two groups of movable block 10, movable spring 14 is connected between one group of movable block 10 and the recess of guide rail 6, telescopic rod 15 is installed on the side of storage box 8, reset spring 16 is installed in telescopic rod 15, one end of telescopic rod 15 is installed on the bottom of operation table 5, telescopic rod 15 is about the center line of storage box 8 and symmetrically installed with two groups.

[0028] In specific implementation, the resistance adjusting structure of the load test box can push the ejector rod 12 to the inside of the guide rail 6 when it is needed to store the tool, so that the ejector rod 12 pushes the movable block 10 to move, and the movable block 10 drives the clamping block 11 on the inner wall to move to one side, at this time, the clamping block 11 is separated from the fixed block 9 at the bottom of the sliding block 7, and the connecting rod 13 between the two movable blocks 10 makes the other movable block 10 move repeatedly according to the above steps, and the movable spring 14 on one side of the movable block 10 is extruded, and the clamping block 11 on the inner wall of the movable block 10 limits the fixed block 9 at the bottom of the sliding block 7, and then the reset spring 16 in the telescopic rod 15 is reset, so that the telescopic rod 15 is elongated as a whole, one side of the telescopic rod 15 is connected with the storage box 8, and the telescopic rod 15 is elongated to push the storage box 8 to move, so that the storage box 8 slides out from the bottom of the operation table 5 through the sliding block 7 along the guide rail 6, thereby facilitating the user to store the tool.

[0029] When it is needed to fix the storage box 8, the storage box 8 is pushed to the bottom of the operation table 5 through the sliding block 7 and the guide rail 6, at this time, the fixed block 9 at the bottom of the sliding block 7 extrudes the clamping block 11, because one end of the clamping block 11 is a slope structure, the clamping block 11 is extruded by the fixed block 9 to push the movable block 10 to move to one side of the guide rail 6, and the movable block 10 extrudes the movable spring 14 in the groove of the guide rail 6, when the groove on one side of the fixed block 9 is aligned with the clamping block 11, the movable spring 14 is reset and pushes the movable block 10 to move reversely, when the movable block 10 moves reversely, the clamping block 11 is butted into the groove on the side of the fixed block 9, so that the sliding block 7 can be limited in the guide rail 6 through the fixed block 9, and the storage box 8 can be stably limited at the bottom of the operation table 5.

[0030] As can be seen from Figure 2 , Figure 3 and Figures 5-8 , in use, the ejector rod 12 can be extruded according to the use requirement, the ejector rod 12 pushes the movable block 10 to move, so that the clamping block 11 on the inner wall of the movable block 10 does not limit the fixed block 9 at the bottom of the sliding block 7, and then the storage box 8 is pushed out through the telescopic rod 15 and the reset spring 16, thereby facilitating the storage of commonly used tools.

[0031] The top of the operation table 5 is provided with a sliding groove 17, the sliding groove 17 is slidably connected with a sliding block 18, two groups of sliding blocks 18 are connected with a cleaning push plate 19, one side of the operation table 5 is provided with a mounting frame 20, the mounting frame 20 is internally provided with a collecting box 21 through a groove, the collecting box 21 is slidably installed in the mounting frame 20 through guide blocks on two sides, one side of the collecting box 21 is attached to one side of the operation table 5, the cleaning push plate 19 forms a sliding structure through the sliding block 18 and the sliding groove 17, and the sliding groove 17 is symmetrically provided with two groups about the center line of the operation table 5.

[0032] In specific implementation, when the top of the operating table 5 needs to be cleaned, the resistance adjustment structure of the load test box only needs to pull the cleaning push plate 19, so that the cleaning push plate 19 slides along the slide groove 17 on the top of the operating table 5 through two sets of sliding blocks 18. Since the bottom of the cleaning push plate 19 is in contact with the surface of the operating table 5, the cleaning push plate 19 can push the dirt and waste on the top of the operating table 5 to move when it moves.

[0033] Meanwhile, a collection box 21 is installed on one side of the operating table 5, and the collection box 21 is slidably installed on the top of the mounting bracket 20 through a groove. One side of the collection box 21 is attached to one side of the operating table 5. At this time, the dirt on the operating table 5 will be pushed into the collection box 21 through the cleaning push plate 19, so as to facilitate the collection and cleaning of dirt and waste on the operating table 5.

[0034] See Figures 1-4 and Figure 7 It can be seen that during use, the cleaning push plate 19 can be pushed according to the usage needs. When the cleaning push plate 19 moves, it can push the dirt and waste on the operating table 5 to move synchronously and push the dirt and waste into the collection box 21 on one side of the operating table 5, thereby facilitating the cleaning of the top of the operating table 5.

[0035] In summary: When using the resistance adjustment structure of this load test box, the control host 1 can be placed in a stable position, then the wiring 4 can be connected to the power supply, and the control host 1 can be started to enable it to work normally.
