[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0026] As Figures 1 to 6 shown, the present embodiment proposes a tailless screw sleeve installation tool, comprising:

[0027] The handle body 1 is provided with a containing cavity at one end;

[0028] The limiting sleeve 2 is clamped in the containing cavity;

[0029] The tool inner core 3 comprises a threaded portion and a connecting portion connected with each other, the connecting portion is arranged in the limiting sleeve 2, the threaded portion is exposed outside the containing cavity and the limiting sleeve 2, and a groove is formed in the tool inner core 3, the groove is arranged with the threaded portion and the connecting portion;

[0030] The tool hook 4 is clamped in the groove and has a hook head, the hook head is located at the end of the threaded portion and is exposed from the groove.

[0031] In this embodiment, the tailless screw sleeve installation tool comprises a handle body 1, a limiting sleeve 2, a tool inner core 3 and a tool hook 4. The handle body 1 is provided with a containing cavity at one end, the opening of the containing cavity is located on the end face of the end of the handle body 1, the limiting sleeve 2 is clamped in the containing cavity, the end of the limiting sleeve 2 is exposed outside the containing cavity and covers the end face of the handle body 1, the tool inner core 3 comprises a threaded part and a connecting part, the connecting part is arranged in the limiting sleeve 2, the threaded part is exposed outside the limiting sleeve 2, the threaded part is used for being screwed into the inside of the tailless screw sleeve (the inside of the tailless screw sleeve is provided with threads), the tool inner core 3 is provided with a groove, the groove is arranged on the threaded part and the connecting part, the tool hook 4 is arranged in the groove, since a part of the groove is located in the containing cavity, a part of the tool hook 4 is also located in the containing cavity, the end of the tool hook 4 is provided with a hook head, the hook head is located at the end of the threaded part, and a part of the hook head is exposed outside the groove. When it is needed to install the tailless screw sleeve into the threaded hole by using the tailless screw sleeve installation tool, the tailless screw sleeve is first installed on the threaded part of the tool inner core 3 until the hook head of the tool hook 4 contacts with the reserved installation part of the tailless screw sleeve, then the tailless screw sleeve is screwed into the threaded hole, when the tailless screw sleeve enters the threaded hole, the tailless screw sleeve installation tool is reversely rotated to realize the separation of the tailless screw sleeve installation tool and the tailless screw sleeve. The limiting sleeve 2 is elastic, since the tool inner core 3 is connected with the handle body 1 through the limiting sleeve 2, the elastic limiting sleeve 2 can not only provide the limiting effect but also provide the automatic leveling effect during the installation of the tailless screw sleeve.

[0032] The handle body 1 and the limiting sleeve 2 can be made of plastic material, so that the production cost is reduced and the production efficiency is improved.

[0033] Further, as shown in Figure 4 and Figure 6 , the outer edge of the limiting sleeve 2 is provided with a first limiting protrusion 5, and the inner wall of the containing cavity is provided with a first limiting groove, and the first limiting protrusion 5 is arranged in the first limiting groove.

[0034] In this embodiment, since the limiting sleeve 2 needs to limit the relative rotation between the tool inner core 3 and the handle body 1, the first limiting protrusion 5 is arranged on the outer edge of the limiting sleeve 2, and the first limiting groove is arranged on the inner wall of the corresponding position of the containing cavity. Since the limiting sleeve 2 is elastic as a whole, the first limiting protrusion 5 is also elastic. When the limiting sleeve 2 is arranged in the containing cavity, the first limiting protrusion 5 needs to be arranged in the first limiting groove. When the tool inner core 3 is arranged in the limiting sleeve 2, the first limiting protrusion 5 can be in close contact with the first limiting groove under the extrusion of the tool inner core 3, so that the relative rotation between the tool inner core 3 and the handle body 1 is avoided.

[0035] Further, as shown in Figures 4 to 5As shown, the embodiment proposes that the outer edge of the tool hook 4 is provided with a second limiting protrusion 6, and the inner wall of the groove is provided with a second limiting groove, and the second limiting protrusion 6 is inserted into the second limiting groove.

[0036] In this embodiment, in order to avoid the relative rotation between the tool hook 4 and the tool inner core 3, a second limiting protrusion 6 is arranged on the outer edge of the tool hook 4, and a second limiting groove is arranged on the inner wall of the corresponding part of the groove. The second limiting protrusion 6 can be inserted into the second limiting groove. Through the cooperation of the second limiting protrusion 6 and the second limiting groove, the relative rotation between the tool hook 4 and the tool inner core 3 in the circumferential direction can be avoided.

[0037] Further, as shown, Figures 1 to 2 The embodiment proposes that the outer part of the handle body 1 is provided with an anti-skid sleeve 7.

[0038] In this embodiment, in order to improve the installation efficiency of the tailless screw sleeve, an anti-skid sleeve 7 is arranged on the outer part of the handle body 1, and the anti-skid sleeve 7 is arranged on the hand-held part of the handle body 1.

[0039] In an actual application, the anti-skid sleeve 7 is injection molded on the outer part of the handle body 1 in a secondary molding manner, and then the two form an integral form, which can not only avoid the relative rotation between the anti-skid sleeve 7 and the handle body 1, but also improve the production efficiency.

[0040] Further, as shown, Figures 1 to 2 The embodiment proposes that the hand-held part of the handle body 1 is provided with an anti-skid plane 8.

[0041] In this embodiment, the anti-skid plane 8 is also arranged on the hand-held part of the handle body 1, which is convenient for the user to operate. This arrangement not only improves the appearance, but also has high installation efficiency when the user installs the tailless screw sleeve.

[0042] Further, as shown, Figures 1 to 4 The embodiment proposes that it also includes an auxiliary rotating head 9, which is sleeved on the end part of the handle body 1 and rotationally connected with the handle body 1.

[0043] In this embodiment, in order to further improve the installation efficiency of the tailless screw sleeve, an auxiliary rotating head 9 is installed on the end part of the handle body 1, and the auxiliary rotating head 9 is in a clearance fit form with the handle body 1. Through the rotation of the auxiliary rotating head 9, the operator can more accurately control the rotation angle and force of the installation tool, thereby improving the quality and efficiency of the installation. For example, when installing the tailless screw sleeve, the auxiliary rotating head 9 can help the operator to rotate the tailless screw sleeve into the correct position, avoiding damage or insecure installation due to improper force.

[0044] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
