[0023] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0024] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Reference Figure 1-Figure 3 According to an embodiment of a split bolt of the utility model, it includes a threaded portion 11, and the upper side of the threaded portion 11 is sequentially provided with an abutment portion 12 and a columnar portion 13, and the upper side surface of the columnar portion 13 is provided with a hexagonal groove 14. When a staff member needs to rotate the split bolt, the staff member can insert a hexagonal wrench into the hexagonal groove 14 and rotate the split bolt.

[0026] In addition, a groove 15 is provided in the lower side surface of the hexagonal socket 14, and a strong glue is filled in the groove 15. A sealing film covering the groove 15 is provided in the hexagonal socket 14, and a connecting member 21 is also provided. The connecting member 21 includes a middle part 22 and an outer hexagonal column 23 connected to the upper and lower ends of the middle part 22 and capable of being inserted into the hexagonal socket 14. The connecting member 21 is also provided with an insert 24 capable of being inserted into the groove 15.

[0027] The staff can also insert one of the outer hexagonal columns 23 into the inner hexagonal groove 14 and then put the socket wrench on the other outer hexagonal column 23, so as to drive the threaded portion 11 to rotate through the socket wrench.

[0028] When the wall of the inner hexagonal groove 14 is worn and causes thread stripping, the staff can insert the insert 24 in the connecting piece 21 into the groove 15. At this time, the super glue in the groove 15 overflows and connects the outer hexagonal column 23 with the wall of the inner hexagonal groove 14 (or fills the gap between the outer hexagonal column 23 and the inner hexagonal groove 14). At this time, the staff can put a socket wrench on the other outer hexagonal column 23, so that the threaded portion 11 can be rotated.

[0029] The specific installation method of the insert 24 is as follows: two inserts 24 are provided and are respectively connected to the two outer hexagonal columns 23, a connecting rod 25 is provided at the end of the insert 24 on the lower side, and an elastic buckle 27 connected to the connecting rod 25 is provided in the bottom surface of the inner hexagonal groove 14, and two elastic buckles 27 are provided and are located on both sides of the groove 15.

[0030] The worker can rotate the split bolt by putting a socket wrench on the outer hexagonal column 23 on the upper side, and in this case, the insert 24 will not enter the groove 15.

[0031] When the wall surface of the hexagonal inner groove 14 is worn and the connecting piece 21 can slide relative to the hexagonal inner groove 14, the staff pulls out the connecting piece 21 and inverts the connecting piece 21. At this time, the connecting rod 25 faces upward. Then the staff inserts the inverted connecting piece 21 into the hexagonal inner groove 14 and presses it downward. At this time, the insert 24 without the connecting rod 25 can be inserted into the groove 15 and the overflowing super glue is attached between the outer hexagonal column 23 and the hexagonal inner groove 14 to eliminate the influence of the wear of the hexagonal inner groove 14. After that, the connecting piece 21 and the hexagonal inner groove 14 are fixed to each other, and the threaded portion 11 can no longer be rotated by a hexagonal wrench.

[0032] In addition, the diameter of the lower side of the abutment portion 12 is greater than the outer diameter of the threaded portion 11, and also includes a shock-absorbing washer 28. The shock-absorbing washer 28 is attached to the lower side of the abutment portion 12, and the shock-absorbing washer 28 is sleeved outside the threaded portion 11 to prevent the split bolt from loosening when the installation platform of the split bolt vibrates.

[0033] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
