[0030] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Referring to Figures 1-4 , an embodiment provided by the present invention: a high-precision traction weight-increasing device, including a weight-increasing bottom plate 1, a plurality of weight-increasing blocks 8 and a base 16. A U-shaped plate 2 is fixedly arranged at the rear end of the upper end surface of the weight-increasing bottom plate 1. A limiting top plate 3 is fixedly arranged on the upper end surface of the U-shaped plate 2. Slots 9 are opened at the rear positions on both sides of the plurality of weight-increasing blocks 8. A plurality of cavities 10 are opened at the front positions on both sides of the U-shaped plate 2. A first straight rod 11 is penetrated through each of the plurality of cavities 10. A limiting spring 12 is sleeved on the outer side of each of the plurality of first straight rods 11. A limiting block 13 is fixedly arranged on the outer side of each of the plurality of first straight rods 11. An insertion block 14 is fixedly arranged at one end of each of the plurality of first straight rods 11 close to the weight-increasing block 8.

[0032] A rotating rod 20 is penetrated through the lower position on one side of the base 16. A second bevel gear 19 is fixedly arranged at one end of the rotating rod 20 close to the base 16. A first bevel gear 18 is meshed with the second bevel gear 19. A first threaded rod 17 is penetrated through the center position on the upper end surface of the first bevel gear 18. A second threaded rod 23 is threadedly sleeved on the upper end surface of the first threaded rod 17. A limiting plate 21 is fixedly arranged at one end of the second threaded rod 23 away from the first bevel gear 18.

[0033] The weight-increasing block 8 is embedded in the U-shaped plate 2. The weight-increasing block 8 presses the insertion block 14. The shape of the insertion block 14 is trapezoidal, so that the two insertion blocks 14 move away from the weight-increasing block 8. The insertion block 14 is subjected to the resilience of the limiting spring 12 to make the insertion blocks 14 respectively embedded in the two slots 9 on the same weight-increasing block 8, which is convenient for adding the weight-increasing block 8.

[0034] A plurality of limiting blocks 13 are respectively arranged on one side of the inner wall of the cavity 10 near the position of the insertion block 14. One ends of a plurality of limiting springs 12 are connected to one side of the inner wall of the cavity 10, and the other ends are connected to the sides of the limiting blocks 13 away from the insertion block 14. The insertion blocks 14 that are opposite to each other among the plurality of insertion blocks 14 are respectively inserted into the slots 9 of a weight increasing block 8 at the same height; a hole 6 is formed at the front position of the upper end surface of the weight increasing bottom plate 1, a through hole 7 is formed at the front position of the upper end surface of the limiting top plate 3, a second straight rod 22 is movably arranged in the through hole 7, the position of the through hole 7 is vertically aligned with the position of the hole 6 up and down, one end of the second straight rod 22 is inserted into the hole 6, and the other end penetrates through the through hole 7; spring telescopic rods 15 are fixedly arranged at both ends of the upper end surface of the base 16, and the other ends of the two spring telescopic rods 15 are respectively connected to the lower end surface of the weight increasing bottom plate 1; the base 16 is in a C shape, one end of a first threaded rod 17 is connected to the bottom surface of the base 16, and the other end penetrates through the inner top surface of the base 16; a connecting rod 4 is fixedly arranged at the center position of the upper end surface of the limiting top plate 3, and a pull ring 5 is fixedly arranged on the upper end surface of the connecting rod 4; a chute 24 is formed in the inner wall of the base 16 near the limiting plate 21, and one end of the limiting plate 21 is slidably arranged in the chute 24.

[0035] Rotate the rotating rod 20 to drive the second bevel gear 19 to rotate. The second bevel gear 19 drives the first bevel gear 18 to rotate. The first bevel gear 18 drives the first threaded rod 17 to rotate, driving the second threaded rod 23 to rotate, so that the second threaded rod 23 drives the limiting plate 21 to slide up and down in the chute 24, facilitating the fixation of the device on objects of different sizes. Tie the traction rope to the pull ring 5, insert the weight increasing block 8 into the U-shaped plate 2. The weight increasing block 8 squeezes the insertion block 14 to make the insertion block 14 move away from the weight increasing block 8. The insertion block 14 drives the first straight rod 11 to move. The limiting block 13 on the first straight rod 11 squeezes the limiting spring 12 to compress the limiting spring 12. When the two slots 9 on the weight increasing block 8 are vertically opposite to the two insertion blocks 14 at the same height, the insertion block 14 is subjected to the resilience of the limiting spring 12, so that the two insertion blocks 14 are respectively inserted into the corresponding slots 9. When it is necessary to reduce the weight increasing block 8, pull the two opposite first straight rods 11 to make the two insertion blocks 14 respectively disengage from the two slots 9 on the weight increasing block 8 at the same height, and then remove the weight increasing block 8 from the U-shaped plate 2, which is convenient for increasing and reducing the weight increasing block 8 so as to adjust the traction force of the device. Insert the second straight rod 22 into the through hole 7, and one end of the second straight rod 22 is inserted into the hole 6 to limit the position of the weight increasing block 8, preventing the weight increasing block 8 from detaching from the device under the influence of the outside during use and causing secondary injury to the patient. After adding the weight increasing block 8, the resilience of the spring telescopic rod 15 buffers the increased traction force of the device, preventing secondary injury to the patient.

[0036] Working principle: When it is necessary to add the weight block 8, place the weight block 8 in the U-shaped plate 2. The weight block 8 squeezes the two plug blocks 14 at the same height, causing the two plug blocks 14 to move away from the weight block 8. The plug blocks 14 are subjected to the resilience of the limit spring 12, causing the two plug blocks 14 to be respectively inserted into the corresponding slots 9. When it is necessary to reduce the weight block 8, pull out the second straight rod 22, pull the two first straight rods 11 opposite to each other, so that the two plug blocks 14 are respectively disengaged from the two slots 9 on the weight block 8 at the same height, and then the weight block 8 is disengaged from the U-shaped plate 2.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
