Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0028] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] The utility model is described in detail below in conjunction with the accompanying drawings.

[0031] like Figure 1 As shown, a shaft system installation anti-rotation tool of the utility model comprises: a tool guide rail 1 and an anti-rotation threaded connector.

[0032] The tooling guide rail 1 includes two slide rails parallel to each other, and a long strip through hole is provided inside the tooling guide rail 1 .

[0033] The anti-rotation threaded connector includes a first anti-rotation threaded connector 2 and a second anti-rotation threaded connector 3. The sizes of the first anti-rotation threaded connector 2 and the second anti-rotation threaded connector 3 are different. Specifically, the screw length of the first anti-rotation threaded connector 2 is greater than the screw length of the second anti-rotation threaded connector 3.

[0034] The anti-rotation threaded connector passes through the long strip through hole of the tooling guide rail 1, and the first anti-rotation threaded connector 2 and the second anti-rotation threaded connector 3 both have connector ends with a diameter greater than the width of the long strip through hole of the tooling guide rail 1, and the connector ends of the anti-rotation threaded connectors both contact the top end of the tooling guide rail 1.

[0035] The anti-rotation threaded connector is arranged between the two slide rails of the tooling guide rail 1. A tooling threaded matching piece 4 and a tooling slide block 5 are installed on one end of the anti-rotation threaded connector passing through the tooling guide rail 1. Specifically, the anti-rotation threaded connector is a bolt, and the tooling threaded matching piece 4 is a nut.

[0036] One side of the tooling slide block 5 contacts the bottom end of the tooling guide rail 1, and the other side contacts the tooling threaded matching piece 4. The tooling slide block 5 is fixed to the anti-rotation threaded connector through the tooling threaded matching piece 4.

[0037] The tooling slide block 5 includes an intermediate connection part, and the two ends of the intermediate connection part are respectively connected with a U-shaped groove, the two U-shaped grooves are arranged in parallel and have the same opening direction, and the two U-shaped grooves are matched with the slide rail. The two U-shaped grooves are respectively installed at the bottom of the two slide rails of the tooling guide rail 1.
