Description

Sleeve Tool

BACKGROUND OF THE DISCLOSURE

Technical Field

The present disclosure relates to a sleeve tool which is suitable to attach and detach a product with a slotted round nut.

Description of the Related Art

In the prior art, it is often desired to attach a product with a slotted round nut to a mounting member. For example, FIG. 4 shows a schematic view of attaching a product 100 with a slotted round nut 110 to a mounting member 210 of a mounting panel 200.

As shown in FIG. 4, the product 100 is adapted to be attached by threaded connection onto the mounting member 210 of the mounting panel 200 by means of a slotted round nut 110 thereon. A groove 110a adapted to engage with a hook-shaped front end 310 of a hook wrench 300 is formed on an outer wall of the slotted round nut 110. Thus, as shown in FIG. 4, when the hook-shaped front end 310 of the hook wrench 300 is engaged with the groove 110a of the slotted round nut 110, the slotted round nut 110 may be driven to rotate by rotating the hook-shaped front end, so that the slotted round nut 110 may be attached by threaded connection onto or detached from the mounting member 210 of the mounting panel 200. In this way, the product 100 having the slotted round nut may be attached or detached.

However, in the prior art, sometimes it is necessary to attach a plurality of products 100 on the mounting panel 200. In order to reduce the size of the entire mounting panel 200, it is desired that a plurality of products 100 are disposed on the mounting panel 200 at a higher density. For example, as shown in FIG. 2, a plurality of products 100 are arranged in an array on the mounting panel 200, with a very small gap between the housings of the adjacent two products 100. In this case, it is difficult to attach or detach the product 100 by using the hook wrench 300 directly, since the gap between the housings of the adjacent two products 100 is very small and the hook wrench 300 will interfere with the housing of the adjacent product 100. Therefore, in the prior art, the products 100 have to be attached or detached one by one in a predetermined order, for example, from bottom to top and from left to right. In the case where it is desired to attach or detach a certain one of the plurality of products 100 arranged in an array, the certain product 100 needs to be attached or detached after all the remaining products 100 before the certain product 100 are attached or detached in the predetermined order. As a result, it is difficult and complicated to attach and detach the product 100, reducing the efficiency of attaching and detaching the products 100.
