Furthermore, a fitting portion is provided at the lower portion of the hexagonal socket head, and the fitting portion is conical and has a hexagonal cross section.

Based on the above technical solution, the following technical effects can be produced:

The utility model provides a sleeve conversion tool, which fits the high lock nut through the hexagonal hole at the bottom of the conversion joint, and the hexagonal head passes through the conversion joint and fits with the hexagonal inner hole of the upper jaw of the high lock bolt through the fitting part of the lower part to fix the high lock bolt. During assembly, only one hand is needed to hold the holding rod to fix the core rod device, and the other hand can pass the torque to the high lock nut through the ratchet wrench knob conversion joint. The installation is completed by twisting off the high lock nut. The tool is simple to operate, which can improve efficiency during assembly, solve the problem of limited installation, and improve the installation quality in a small area. It can be easily operated, reduce the risk of parts damage and scrap rate, and save costs for enterprises. .

DETAILED DESCRIPTION

It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments 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.

As shown in Figures 1 to 5, a sleeve conversion tool is used for the installation of twist-off high-locking bolts and nuts, including a conversion joint 1 and a core rod device. The conversion joint 1 is a hexagon socket type conversion joint. The lower part of the conversion joint 1 is fitted with a high-locking nut 4. The core rod device includes a handle 2 and a hexagon head 3. The hexagon head 3 passes through the conversion joint 1 and is fitted with the high-locking bolt 5.

According to an embodiment of the utility model, a hexagonal nut is provided on the upper portion of the conversion joint 1, and the hexagonal nut is engaged with a ratchet wrench.

According to an embodiment of the present utility model, the hole at the lower end of the conversion joint 1 is a hexagonal hole.

According to an embodiment of the present utility model, the handle 2 comprises a gripping rod 2.1 and a connecting rod 2.2, the gripping rod 2.1 and the connecting rod 2.2 are vertically connected, and an internal threaded hole is arranged at the lower end of the connecting rod 2.2.

According to one embodiment of the utility model, an external thread is provided on the upper portion of the hexagonal head 3, the hexagonal head 3 and the connecting rod 2.2 are detachably connected by threads, the hexagonal head 3 and the handle 2 are connected by tightening the threads, and can be replaced according to the required size.
