The surface of the sliding block 703 is threadedly connected to a limit screw 710. One end of the limit screw 710 is against the side wall of the adjustment frame 704, which can facilitate the staff to quickly connect the detection screw rods 5 of different sizes with the driver 13, thereby improving the efficiency of detecting the detection screw rod 5 that needs to be detected, facilitating the use of the detection device, and eliminating the need for the staff to lift and install it, reducing the labor intensity of the staff to install the detection screw rod 5, thereby increasing the convenience of the staff's work. Both sides of the sliding plate 701 are slidably connected to a plurality of rollers 702, a plurality of The rollers 702 are linearly arrayed on the side wall of the sliding plate 701, and several rollers 702 are slidably connected to the workbench 1. The rollers 702 are fitted to the workbench 1, which can reduce the friction generated when the sliding plate 701 slides, making it convenient for the staff to pull the sliding plate 701 and improve the smoothness of the movement of the sliding plate 701. The inner wall of the adjustment frame 704 is rotatably connected with a ring 705, and the ring 705 can reduce the friction generated between the adjustment frame 704 and the adjustment frame 704 when the detection screw rod 5 rotates, so as to ensure the smoothness of the rotation of the detection screw rod 5, so that the bidirectional screw rod 711 will not be subject to resistance when rotating, and the surface sliding of the adjustment frame 704 It is connected with an insertion rod 709, and the surfaces of the two moving blocks 713 are provided with slots 715. The size of the slots 715 is matched with the size of the insertion rod 709. The insertion rod 709 is inserted into the interior of the slots 715, and the bidirectional screw 711 is further rotated.

[0048] like Figure 1 and Figure 6 as well as Figure 7As shown, the lubricating device 8 also includes three round rods 802, and the three round rods 802 are all slidably connected to the long plate 801. The ends of the three round rods 802 away from the long plate 801 are fixedly connected to the connecting plate 803, and the ends of the three round rods 802 away from the connecting plate 803 are fixedly connected to the plugging plate 805. The surfaces of the four slide rails 2 are slidably connected to two sliding racks 808, and the surfaces of the sliding racks 808 are fixedly connected to the limit frame 806. The size of the inner wall of the limit frame 806 is adapted to the size of the plugging plate 805. The surfaces of the two sliding racks 808 are fixedly connected to liquid bottles 807, and the infusion tube 809 is fixedly connected to the sliding racks 808. The infusion tube 809 is fixedly connected to the liquid bottle 807. When the first fixing member 3 and the second fixing member 4 move, the sliding racks 808 are driven to move so as to apply the lubricating oil to the surface of the slide rail 2, so that the first fixing member 3 and the second fixing member 4 can be moved. After long-term use, it can still maintain good operation, will not get stuck during use, and will not be damaged, thereby improving the service life of the first fixing member 3 and the second fixing member 4, and the surfaces of the three round rods 802 are all covered with springs 804, and the two ends of the springs 804 are fixedly connected to the long plate 801 and the connecting plate 803 respectively, and the springs 804 can press the plug plate 805 tightly against the inside of the limit frame 806 and will not slide out, thereby improving the stability of the limit installation of the sliding frame 808, and the inner walls of the two sliding frames 808 are glued with wiping blocks 810, and the wiping blocks 810 are made of sponge material. The wiping blocks 810 are against the output port of the infusion tube 809. Since the wiping blocks 810 are made of sponge material, when the lubricating oil is dripped onto the surface of the wiping blocks 810, the wiping blocks 810 can evenly apply the lubricating oil to the surface of the slide rail 2, which can improve the lubrication effect of the lubricating device 8.

[0049] like Figure 8 and Fig. 9 as well as Fig.10 As shown, the winding device 9 also includes a slide plate 92, which is slidably connected to the extension plate 91, and a rotating rod 93 is rotatably connected to the upper surface of the extension plate 91. One end of the rotating rod 93 is fixedly connected to a rotating block 95, and a cross groove 96 is provided on the surface of the rotating block 95. A cross block 87 is fixedly connected to the surface of the slide plate 92, and the size of the cross block 87 is adapted to the size of the cross groove 96. Before using the controller 11, the connecting line 12 is limited by the winding of the rotating rod 93, so that the connecting line 12 will not be scattered on the ground, and then when the staff uses the controller 11, the connecting line 12 will not trip over the connecting line 12, thereby improving the safety of the staff when using the controller 11 to adjust the magnetic powder brake 10, and a plurality of cylinders 94 are fixedly connected to the surface of the rotating rod 93, and the plurality of cylinders 94 are arranged in a circular array on the surface of the rotating rod 93. When the connecting line 12 is wound, the cylinder 94 can limit the connecting line 12, so that the connecting line 12 will not rotate when it is wound, thereby improving the winding stability of the connecting line 12.

[0050] Working principle: When the detection screw rod 5 is detected, the driver 13 can drive the detection screw rod 5 to rotate, and the first fixing member 3 will move on the surface of the detection screw rod 5. Since the first fixing member 3 and the second fixing member 4 are slidably connected together, the brake screw rod 6 can be driven to rotate. At this time, the staff can control the magnetic powder brake 10 through the controller 11, and can adjust the resistance of the brake screw rod 6 when rotating, thereby increasing the detection effect of the detection screw rod 5. When installing detection screw rods 5 of different sizes,First, the fixed plate 14 is removed, and then the original detection screw rod 5 is removed from the side where the fixed plate 14 is removed, and then the sliding plate 701 is slid out from the inside of the workbench 1. Rollers 702 are rotatably connected on both sides of the sliding plate 701. The rollers 702 are attached to the workbench 1, which can reduce the friction generated when the sliding plate 701 slides, making it convenient for the staff to pull the sliding plate 701. Further, the staff can pass the detection screw rod 5 to be installed through the adjustment frame 704, and then place one end of the detection screw rod 5 on the surface of the arc plate 714, and then insert the insertion rod 709 into the inside of the slot 715, and further rotate the bidirectional screw 711. When the staff lifts the adjusting frame 704, the rotation of the bidirectional screw 711 can drive the moving block 713 to move, and then drive the two arc plates 714 to move in the direction close to each other, so as to realize the limiting work of the detection screw rod 5. At the same time, the staff can use the plug rod 709 to facilitate the height adjustment of the adjusting frame 704, and can adjust the detection screw rod 5 to a horizontal position. Further, the staff rotates the limiting screw rod to complete the limiting of the adjusting frame 704, so that the adjusting frame 704 will not slide. Further, the staff can push the sliding plate 701 to move the sliding plate 701 in the direction of the first fixing member 3. When the end of the screw rod 708 contacts the surface of the first fixing member 3, the staff can start the motor 707, and the motor 707 can drive the turntable 708 to rotate, thereby driving the detection screw rod 5 to rotate, and the detection screw rod 5 can be threadedly connected to the internal thread groove of the first fixing member 3. There is a ring 705 inside the adjusting frame 704, and the ring 705 can reduce the friction generated between the adjusting frame 704 and the detection screw rod 5 while rotating, so as to ensure the smooth rotation of the detection screw rod 5. After passing through the first fixing member 3, the staff can rotate the bidirectional screw rod 711 in the opposite direction, so that the detection screw rod 5 can be disengaged from the limit, and then the detection screw rod 5 can be moved so that one end of it contacts the driver 13. At this time, the staff can connect the detection screw rod 5 with the driver 13, and further connect the other end with the fixing plate 14, and install the fixing plate 14 on the surface of the workbench 1. At this time, the installation of the detection screw rod 5 is completed, and the driver 13 can be started to detect the durability. By setting the auxiliary device 7, it is convenient for the staff to quickly connect the detection screw rods 5 of different sizes with the driver 13, thereby improving the efficiency of detecting the detection screw rod 5 that needs to be detected, facilitating the use of the detection device, and no need for the staff to lift and install, reducing the labor intensity of the staff to install the detection screw rod 5, thereby increasing the convenience of the staff's work. ,

[0051] When the first fixing member 3 and the second fixing member 4 are moved, the round rod 802 can be used to drive the plug plate 805 to insert into the inner wall of the limit frame 806, and the connection with the sliding frame 808 can be completed at this time, and a spring 804 is sleeved on the surface of the round rod 802, and the spring 804 can press the plug plate 805 tightly against the inside of the limit frame 806 and will not slide out, thereby improving the stability of the limited installation of the sliding frame 808. Further, when the first fixing member 3 and the second fixing member 4 are moved, the sliding frame 808 can be driven to move on the surface of the slide rail 2. At the same time, when moving, the lubricating oil in the liquid bottle 807 can be dripped onto the surface of the slide rail 2 through the infusion tube 809, so that the slide rail 2 is connected with the first fixing member 3 and the second fixing member The sliding parts 4 can maintain smooth sliding without getting stuck. At the same time, a wiping block 810 is provided on the inner wall of the sliding frame 808. Since the wiping block 810 is made of sponge material, when the lubricating oil is dripped onto the surface of the wiping block 810, the wiping block 810 can evenly apply the lubricating oil to the surface of the slide rail 2, thereby improving the lubrication effect of the lubricating device 8. By setting the lubricating device 8, when the first fixing member 3 and the second fixing member 4 move, the sliding frame 808 can be driven to move so as to apply the lubricating oil to the surface of the slide rail 2, thereby enabling the first fixing member 3 and the second fixing member 4 to maintain good operation after long-term use, without getting stuck during use, and thus without being damaged, thereby improving the service life of the first fixing member 3 and the second fixing member 4.

[0052] Before using the controller 11, the staff can first wind the middle section of the connecting line 12 onto the surface of the rotating rod 93, and further drive the rotating rod 93 to rotate through the rotating block 95, which can help the connecting line 12 to start winding from the middle section, so that the connecting line 12 will not be scattered on the ground. At the same time, the arc surface of the rotating rod 93 has a cylinder 94. When the connecting line 12 is wound, the cylinder 94 can limit the connecting line 12, so that the connecting line 12 will not rotate when it is wound, thereby improving the winding stability of the connecting line 12. Further, the staff can slide the slide plate 92, and the cross block 8 can be driven by the slide plate 92 7 is inserted into the cross groove 96, and the rotation rod 93 can be limited at this time, so that the rotation rod 93 will not rotate when not in use, and the connecting line 12 will not be separated from the surface of the rotation rod 93, and the winding and limiting can be well performed. By setting the winding device 9, the connecting line 12 can be limited by winding the rotation rod 93 before using the controller 11, so that the connecting line 12 will not be scattered on the ground, and the staff will not trip because of the connecting line 12 when using the controller 11, thereby improving the safety of the staff when using the controller 11 to adjust the magnetic powder brake 10.
