Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

The connecting column and the ratchet are both arranged on the sliding block 3. It should be noted that, in this embodiment, the installation method of the connecting column and the ratchet can refer to the technical content adopted in a ratchet base for anchoring and compensating a high-speed railway load-bearing cable disclosed in a Chinese patent with announcement number CN216331558U in the prior art, which will not be repeated here. A transmission cavity is provided in the base 1, and circular holes are provided on the opposite inner walls of the transmission cavity. A cylinder 4 is installed in the two circular holes for common rotation, and a screw 2 is fixedly installed at one end of the cylinder 4. The screw The other end of the cylinder 4 is rotatably mounted on the inner wall of the side of the base 1, the sliding block 3 is threadedly mounted on the screw 2, a cross slot is provided at the other end of the cylinder 4, a cross slider 5 is slidably mounted in the cross slot, an operating block 6 is fixedly mounted on the side of the cross slider 5, a reset assembly is arranged on the side of the operating block 6, two rectangular frames 8 are slidably mounted in the transmission cavity through a limit assembly, a limit gear 10 is fixedly sleeved on the cylinder 4, and a limit rack 11 is slidably mounted in the two rectangular frames 8 through a guide compression assembly, a square plate 13 is rotatably mounted on the outer wall of the peripheral side of the operating block 6, and the square plate 13 is connected to the two rectangular frames 8 through a connecting assembly.

[0025] By means of the above structure, when in use, when it is necessary to adjust the horizontal position of the sliding block 3, the hexagonal wrench is inserted into the operating block 6 and pressed to make the operating block 6 move toward the direction of the cylinder 4. When the operating block 6 moves, the two rectangular frames 8 are driven to move synchronously in opposite directions under the action of the two connecting components, and the engagement between the two limit racks 11 and the limit gear 10 is released. Then the operating block 6 is rotated to drive the cross slider 5, the cylinder 4, and the screw 2 to rotate synchronously, thereby driving the sliding block 3 to realize the horizontal movement function under the action of the thread. When it is adjusted to a suitable position, the squeezing of the operating block 6 is released, and the operating block 6 is driven to reset under the action of the reset component, thereby driving the two rectangular frames 8 and the two limit racks 11 to reset synchronously, and meshing with the limit gear 10 to realize the limiting function of the cylinder 4, preventing it from rotating, and having strong stability.

[0026] Example 2

[0027] like Figure 3 As shown, the reset assembly includes a reset spring 7, one end of the reset spring 7 is fixedly mounted on the side of the operating block 6, and the other end of the reset spring 7 is fixedly mounted on the end of the cylinder 4. The reset spring 7 is sleeved on the cross slider 5. The advantage of this arrangement is that, through the arrangement of the reset spring 7, the reset function can be achieved through its elastic action when the squeezing of the operating block 6 is released.

[0028] Specifically, when the squeezing of the operating block 6 is released, the elastic action of the reset spring 7 can drive the operating block 6 to achieve the reset function, thereby driving the square plate 13 to reset synchronously, without the need for manual reset by the staff.

[0029] like Figure 5 As shown, the limit assembly includes two limit shafts 9, both ends of which are fixedly mounted on the opposite inner walls of the transmission cavity, and the two rectangular frames 8 are slidably mounted on the two limit shafts 9. The advantage of this arrangement is that through the arrangement of the two limit shafts 9, the limit function of the rectangular frame 8 can be achieved to prevent it from falling off when sliding.

[0030] Specifically, when the rectangular frame 8 slides horizontally under the action of the connecting assembly, the limiting action of the two limiting shafts 9 enables it to slide horizontally to prevent deviation.

[0031] Example 3

[0032] like Figure 5 As shown, the guide compression assembly includes a guide shaft, a guide hole is opened at the top of the limit rack 11, the guide shaft is slidably installed in the guide hole, and the two ends of the guide shaft are respectively fixedly installed on the relative inner walls of the rectangular frame 8. The advantage of this arrangement is that through the setting of the guide shaft, the sliding of the limit rack 11 can be guided to prevent it from falling off.

[0033] Specifically, when the limit rack 11 contacts the limit gear 10, the meshing of the teeth will cause the limit rack 11 to slide up and down quickly, thereby realizing the meshing function. The guiding function of the guide shaft can prevent it from deflecting or falling off during sliding.

[0034] like Figure 5 As shown, the guide compression assembly also includes two compression springs 12, one end of the two compression springs 12 is fixedly installed on the two side parts of the limit rack 11, and the other ends of the two compression springs 12 are respectively fixedly installed on the opposite inner walls of the rectangular frame 8, and the two compression springs 12 are both sleeved on the guide shaft. The advantage of such an arrangement is that through the arrangement of the two compression springs 12, when the squeezing of the limit rack 11 is released, the resetting function can be quickly achieved through its elastic action.

[0035] Specifically, due to the meshing of teeth, the limit rack 11 will slide up and down quickly, thereby squeezing or stretching the two compression springs 12 respectively. When the meshing of the limit rack 11 and the limit gear 10 is released, the elastic action of the two compression springs 12 can drive the limit rack 11 to reset quickly without manual reset by the staff.

[0036] Example 4

[0037] like Figure 5As shown, the connecting assembly includes a connecting rod 14, and a rectangular hole is opened on the side inner wall of the transmission chamber. The connecting rod 14 is slidably installed in the rectangular hole. One end of the connecting rod 14 is rotatably installed on the side of the square plate 13, and the other end of the connecting rod 14 is rotatably installed on the side of the rectangular frame 8. The advantage of this arrangement is that through the arrangement of the connecting rod 14, the movement of the square plate 13 can drive the rectangular frame 8 to move synchronously.

[0038] Specifically, when the square plate 13 is moving, the two connecting rods 14 can drive the two rectangular frames 8 to achieve synchronous movement toward or away from each other.

[0039] like Figure 1 As shown, a protection box 15 is provided on the side of the base 1, and the protection box 15 is adapted to the operating block 6. A box door 16 is hingedly installed on the side of the protection box 15. The advantage of such a setting is that, through the setting of the protection box 15 and the box door 16, the protection function of the operating block 6 and the compression spring 7 can be achieved to prevent damage caused by long-term exposure to the outside.
