[0024] For details, please refer to Figure 4 The inner walls on both sides of the adjustment box 4 are rotatably connected with a bidirectional screw 10, and each of the two ends of the bidirectional screw 10 is threadedly connected with a thread sleeve 12. The rotation of the bidirectional screw 10 drives the two thread sleeves 12 to move toward or away from each other, and the threads at both ends of the bidirectional screw 10 rotate in opposite directions.
[0025] For details, please refer to Figure 4 The four threaded sleeves 12 are rotatably connected to a connecting plate 11 respectively, and two adjacent connecting plates 11 are rotatably connected to the same sliding seat 13, so that when the threaded sleeves 12 move, the connecting plates 11 can be driven to drive the sliding seat 13 to move.
[0026] For details, please refer to Figure 4A synchronous wheel 14 is coaxially fixedly sleeved on both ends of each bidirectional screw 10, and a synchronous belt 15 is sleeved on the two synchronous wheels 14 in the same plane. The cooperation between the synchronous wheel 14 and the synchronous belt 15 facilitates the synchronous rotation of the two bidirectional screws 10.
[0027] For details, please refer to Figure 4 A rotating disk 5 is rotatably connected to the outer wall of one side of the adjustment box 4, and one end of the transmission shaft of the rotating disk 5 is fixedly connected to one of the bidirectional screws 10.

[0028] For details, please refer to Figure 3 The depth of the mounting groove 8 is greater than the thickness of the fixed rack 9. The fixed rack 9 is hidden by the mounting groove 8, thereby avoiding safety hazards caused by the fixed rack 9 being exposed.
[0029] For details, please refer to Figure 1-3 The inner wall of the fixed sleeve 1 is provided with two sliding grooves, and the inner walls of the two sliding grooves are slidably connected with sliding blocks, and the two sliding blocks are fixedly connected to the measuring rod 3. The setting of the sliding blocks prevents the measuring rod 3 from rotating, thereby affecting the positioning of the fixed rack 9.
[0030] Working principle: During use, when it is necessary to adjust the length of the measuring rod 3, first rotate the rotating disk 5 to drive the bidirectional screw 10 to rotate. When the bidirectional screw 10 rotates, it directly drives the two threaded sleeves 12 to move toward or away from each other. When the two threaded sleeves 12 move away from each other, they directly drive the sliding seat 13 to be collected into the adjusting box 4 through the connecting plate 11, so that the limit rack 7 is away from the fixed rack 9. At this time, the length of the measuring rod 3 is adjusted. After the adjustment is completed, the limit rack 7 and the fixed rack 9 are driven to engage with each other. The two bidirectional screws 10 are connected by a synchronous wheel 14 and a synchronous belt 15, so that the two bidirectional screws 10 can rotate synchronously. When the bidirectional screw 10 rotates, it directly drives the synchronous wheel 14 to rotate. The synchronous wheel 14 bracket is connected through a synchronous belt 15, so that the two synchronous wheels 14 rotate synchronously, and then the two bidirectional screws 10 rotate synchronously.
