[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0049] The prior art requires the use of a ratchet handle and an Allen wrench to complete the installation of high-lock bolts and nuts. The operator needs to hold the Allen wrench in one hand to position the high-lock bolt and use the other hand to turn the ratchet wrench to tighten the nut. This is not convenient for operation in a small space, and the Allen wrench is difficult to hold, making it difficult to use. The utility model provides a high-lock bolt installation tool, which is provided with an auxiliary handle for fixing the bolt positioning member. The ratchet handle rotates relative to the auxiliary handle and drives the nut sleeve to rotate through the connecting member. The auxiliary handle is easy to insert into a small space and is easier to hold, reducing the difficulty of operation.

[0050] Please refer to the attached Figure 1 To the attached Figure 11Now, the high-lock bolt installation tool provided by the present invention is described. The high-lock bolt installation tool includes a ratchet handle 10, an auxiliary handle 50, a bolt positioning member 40 and a nut sleeve 30. The ratchet handle 10 is connected to the nut sleeve 30 and rotates relative to the auxiliary handle 50 to tighten the nut on the high-lock bolt. The bolt positioning member 40 is fixed to the auxiliary handle 50 and the bottom is fixed to the high-lock bolt to limit the high-lock bolt. Specifically, one end of the ratchet handle 10 is equipped with a ratchet assembly, wherein the ratchet shaft in the ratchet assembly is a hollow structure. One end of the auxiliary handle 50 is hinged to the ratchet handle 10 by means of a connecting member 70, wherein the connecting member 70 is inserted into the hollow structure of the ratchet shaft and is clamped with the ratchet shaft. The connecting member 70 is provided with a through hole in the axial direction and a first connecting head 72 is provided at the lower part of the connecting member 70. The bolt locator 40 includes a stop cap 41 and a stop rod 42 connected to the stop cap 41. The stop cap 41 is equipped with a rotation-stop assembly 20 to prevent it from rotating. The stop rod 42 extends through a through-hole in the connector 70, with its end adapted to engage a groove in the high-lock bolt, allowing the connector 70 to rotate freely relative to the stop rod 42. The top end of the nut sleeve 30 is adapted to assemble with the first connector 72 of the connector 70, while its bottom end is adapted to fit over the outer edge of the nut that matches the high-lock bolt. When the bolt locator 40 secures the high-lock bolt, the ratchet handle 10 rotates relative to the auxiliary handle 50, completing the installation of the nut that matches the high-lock bolt. Specifically, the bottom end of the bolt locator 40 features a hexagonal structure 71 that mates with the groove at the top of the high-lock bolt. This hexagonal structure engages with the groove in the high-lock bolt, restricting its rotation. The connector 70 is snapped into the ratchet assembly. Rotating the ratchet handle 10 rotates the connector 70, which in turn rotates the nut sleeve 30. When the ratchet handle 10 rotates back and forth relative to the auxiliary handle 50 , the ratchet assembly can be driven to realize the unidirectional rotation of the connecting member 70 . The structure and working principle of the ratchet assembly are prior art and will not be described in detail here.

[0051] In the embodiment of the present application, the auxiliary handle 50 remains stationary, and the bolt locating member 40 is limited on the auxiliary handle 50 by the anti-rotation assembly 20, which can limit the high-locking bolt and prevent it from rotating. The ratchet handle 10 is fixed to the nut sleeve 30 through the connecting member 70. Rotating the ratchet handle 10 can drive the nut sleeve 30 to rotate, thereby tightening the nut. With the above structure, there is no need to directly hold the bolt locating member 40 with the hand. By controlling the auxiliary handle 50 and the ratchet handle 10, the high-locking bolt can be limited and the nut can be tightened. The auxiliary handle 50 and the ratchet handle 10 are easy to extend into a small space for operation, and are easy to hold and convenient for staff to use.

[0052] In an optional embodiment, the utility model provides a structure for limiting the bolt positioning member 40 and realizing the reset of the ratchet handle 10: the anti-rotation assembly 20 includes a anti-rotation rod passing through the radial direction of the limiting cap 41, and the two ends of the anti-rotation rod are respectively fixedly connected to the auxiliary handle 50. When in use, the auxiliary handle 50 is fixed in position, and the bolt positioning member 40 is fixed to the auxiliary handle 50 through the anti-rotation rod, thereby realizing the limit of the high-locking bolt. Furthermore, a compression spring is connected between the ratchet handle 10 and the auxiliary handle 50 to realize the automatic reset of the ratchet handle 10. When in use, press the ratchet handle 10 to rotate it close to the auxiliary handle 50, and then release the ratchet handle 10. The ratchet handle 10 is reset away from the auxiliary handle 50 under the action of the elastic force of the compression spring. The above operation can be completed with one hand.

[0053] In an optional embodiment, see the attached Figure 1 To the attached Figure 3 The present invention provides another structure for retaining a bolt locator 40 and resetting the ratchet handle 10: the anti-rotation assembly 20 is a torsion spring mounted on a retaining cap 41. One torsion arm of the torsion spring extends through the retaining cap 41 and connects to the auxiliary handle 50, while the other torsion arm connects to the ratchet handle 10. The bolt locator 40 is secured to the auxiliary handle 50 via the torsion arm extending through the retaining cap 41. The other torsion arm applies a torque to the ratchet handle 10, pushing it away from the auxiliary handle 50, ensuring that the ratchet handle 10 automatically resets after it is released.

[0054] In the above two embodiments, the anti-rotation assembly 20 fixes the bolt locator 40 on the auxiliary handle 50 and plays a reset role between the ratchet handle 10 and the auxiliary handle 50, making it convenient for one-handed use of the tool and further reducing the difficulty of use.
