Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of 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.

[0026] Example 1: Please refer to Figures 1 to 6 :

[0027] The utility model proposes a cable fast tightening device, comprising: a support seat 1; a winding wheel 2 is rotatably installed on the right side of the top of the support seat 1, the support seat 1 is used to support the structure on the top of the device, the winding wheel 2 is used to wind the traction rope 4, and the traction rope 4 can be tightened when the winding wheel 2 rotates; a turbine 3 is fixed to the rear side of the winding wheel 2, and when the worm 6 rotates, the winding wheel 2 is driven to rotate through the turbine 3, so the cable can be tightened through the traction rope 4 outside the winding wheel 2; a traction rope 4 is wound around the outside of the winding wheel 2, and a hook is fixed to the right end of the traction rope 4 5. When tightening the line, first pull the traction rope 4 outside the winding wheel 2 outwards, and then hang the two hooks 5 on the left and right sides with the cable to be tightened; a traction rope 4 is also fixed on the left side of the support seat 1, and a hook 5 is also fixed on the left end of the traction rope 4. When tightening the line, first pull the traction rope 4 outside the winding wheel 2 outwards, and then hang the two hooks 5 on the left and right sides with the cable to be tightened; a worm 6 is also rotatably installed on the inside of the support seat 1, and the worm 6 is meshed with the turbine 3. When the worm 6 rotates, it will drive the winding wheel 2 to rotate through the turbine 3, so it can be wound The traction rope 4 on the outside of the reel 2 tightens the cable; a crank 7 is installed on the top of the worm 6, and the crank 7 can be used to drive the worm 6 and the locking rod 8 to rotate when in use, and the crank 7 can be disassembled, so that the crank 7 can be removed and placed on the inside of the support seat 1 when the device is not in use; a locking rod 8 is slidably installed on the inside of the worm 6, and when it is necessary to drive the worm 6 to rotate, the locking rod 8 can be pulled upward to the bottom, and the rectangular block at the bottom end of the locking rod 8 will be separated from the circular block on the inner side of the bottom of the support seat 1, so the worm 6 and the locking rod 8 can be driven to rotate by the crank 7. After tightening the cable, the locking rod 8 can be pushed down to the bottom. At this time, the rectangular block at the bottom end of the locking rod 8 will be embedded in the rectangular groove on the inner circular block at the bottom of the support seat 1, so the locking rod 8 and the worm 6 cannot rotate, thereby locking the turbine 3 and the winding wheel 2 to prevent the tightened cable from loosening; a crank locking buckle 9 is also slidably installed on the outside of the worm 6. During installation, the crank locking buckle 9 can be inserted into the horizontal strip groove on the outside of the hexagonal column at the top of the worm 6, and then the locking buckle 9 can limit the up and down movement of the crank 7, thereby ensuring the stability of the worm 6 when the crank 7 is shaken to drive the worm 6 to rotate.

[0028] In the present disclosure, Figure 1-Figure 6 As shown, a hexagonal column is provided at the top of the worm 6, and a hexagonal hole of corresponding size is provided on one side of the crank 7. During installation, it is only necessary to align the circular hole on one side of the crank 7 with the hexagonal column at the top of the worm 6, and push the crank 7 downward to make the hexagonal column at the top of the worm 6 pass through the circular hole on one side of the crank 7. At this time, the crank locking buckle 9 can be inserted into the horizontal strip groove outside the hexagonal column at the top of the worm 6.

[0029] In the present disclosure, Figure 1-Figure 3As shown, the main part of the locking rod 8 is a rectangular cylindrical rod, and a rectangular cylindrical hole penetrating up and down is provided on the inner side of the worm 6, and the main part of the locking rod 8 can slide up and down in the rectangular cylindrical hole on the inner side of the worm 6, so the locking rod 8 will rotate synchronously with the worm 6. When the locking rod 8 cannot rotate, the worm 6 cannot rotate either, which makes it easy to lock the turbine 3 and the winding wheel 2 to prevent the cable from loosening.

[0030] In the present disclosure, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, two horizontal strip grooves are also provided on the outside of the hexagonal column at the top of the worm 6, and the height of the two horizontal strip grooves is equal to the thickness of the crank locking buckle 9. The crank locking buckle 9 is a U-shaped structure, which will be embedded in the horizontal strip groove on the outside of the hexagonal column at the top of the worm 6 after installation, and at this time, the bottom surface of the crank locking buckle 9 will be tightly attached to the top outer wall of the crank 7. During installation, it is only necessary to align the circular hole on one side of the crank 7 with the hexagonal column at the top of the worm 6, and push the crank 7 downward to make the hexagonal column at the top of the worm 6 pass through the circular hole on one side of the crank 7. At this time, the crank locking buckle 9 can be inserted into the horizontal strip groove on the outside of the hexagonal column at the top of the worm 6, and then the locking buckle 9 can limit the up and down movement of the crank 7, thereby ensuring the stability of the worm 6 when the crank 7 is shaken to drive the worm 6 to rotate.

[0031] In the present disclosure, Figure 1 and Figure 2 As shown, a rectangular block is provided at the bottom of the locking rod 8, and a circular block is provided on the inner side of the bottom of the support seat 1. A rectangular groove with the same cross-sectional size as that of the rectangular block at the bottom of the locking rod 8 is provided on the inner side of the circular block. After tightening the cable, the locking rod 8 can be pushed down to the bottom. At this time, the rectangular block at the bottom of the locking rod 8 will be embedded in the rectangular groove on the circular block on the inner side of the bottom of the support seat 1, so the locking rod 8 and the worm 6 cannot rotate.

[0032] In the present disclosure, Figure 1 and Figure 2 As shown, when the locking rod 8 slides down to the bottom, the rectangular block at its bottom end will be embedded in the rectangular groove on the inner circular block at the bottom of the support seat 1, and when the locking rod 8 slides up to the top, the rectangular block at its bottom end will be disengaged from the inner circular block at the bottom of the support seat 1. When it is necessary to drive the worm 6 to rotate, the locking rod 8 can be pulled upward to the bottom, and at this time, the rectangular block at the bottom end of the locking rod 8 will be disengaged from the inner circular block at the bottom of the support seat 1, so the worm 6 and the locking rod 8 can be driven to rotate by the crank 7. After tightening the cable, the locking rod 8 can be pushed downward to the bottom, and at this time, the rectangular block at the bottom end of the locking rod 8 will be embedded in the rectangular groove on the inner circular block at the bottom of the support seat 1, so the locking rod 8 and the worm 6 cannot rotate, thereby locking the turbine 3 and the winding wheel 2 to prevent the tightened cable from loosening.

[0033] Embodiment 2, based on embodiment 1, as Figure 1-Figure 6 As shown, the main part of the locking rod 8 is a magnet rod, the worm 6 is an iron structure, and the crank locking buckle 9 is also a magnet structure. When the worm 6 needs to be driven to rotate, the locking rod 8 is first pulled upward to the top to unlock it. At this time, the locking rod 8 will be adsorbed with the worm 6, thereby preventing the locking rod 8 from sliding down by itself, and the crank locking buckle 9 can also be adsorbed with the worm 6 after installation, so that the crank locking buckle 9 will not be detached when the worm 6 is rotated.

[0034] The working principle of this embodiment: when using this device to tighten the wire, first install the crank handle 7. During installation, you only need to align the round hole on one side of the crank handle 7 with the hexagonal column at the top of the worm 6, and push the crank handle 7 downward to make the hexagonal column at the top of the worm 6 pass through the round hole on one side of the crank handle 7. At this time, the crank handle locking buckle 9 can be inserted into the horizontal strip groove on the outside of the hexagonal column at the top of the worm 6, and then the locking buckle 9 can limit the up and down movement of the crank handle 7, thereby ensuring the stability of the worm 6 when the crank handle 7 is shaken to rotate. When tightening the wire, first pull the traction rope 4 on the outside of the winding wheel 2 outward, and then hang the two hooks 5 on the left and right sides with the cable to be tightened. At this time, the locking rod 8 can be pulled upward to the bottom, and the rectangular block at the bottom of the locking rod 8 will be separated from the circular block on the inner side of the bottom of the support seat 1. The worm gear 6 and the locking rod 8 are therefore driven to rotate by the crank handle 7. When the worm gear 6 rotates, the winding wheel 2 is driven to rotate through the turbine 3. Therefore, the cable can be tightened by the traction rope 4 outside the winding wheel 2. After the cable is tightened, the locking rod 8 can be pushed down to the bottom. At this time, the rectangular block at the bottom end of the locking rod 8 will be embedded in the rectangular groove on the circular block on the inner side of the bottom of the support seat 1. Therefore, the locking rod 8 and the worm gear 6 cannot rotate, thereby locking the turbine 3 and the winding wheel 2 to prevent the tightened cable from loosening. When the device needs to be folded and carried after use, the crank handle locking buckle 9 can be pulled outward first, and then the crank handle 7 can be disassembled and placed on the inner side of the support seat 1. In this way, the crank handle 7 will not protrude outward when carried and placed, which is more convenient to carry and occupies less vertical space when stored.
