Description

Technical Field

[0001] The utility model relates to the technical field of wrenches, in particular to a socket wrench. Background Art

[0002] Screw bolting is often used as an effective connection method between embedded parts and parts to be connected in important parts of infrastructure projects. Because of its simple structure, reliable connection and low cost, it has been widely used in the installation and disassembly of assembled components on site in recent years. During the construction process, in order to fix the embedded screw at the designed position, a flange is usually added to the top surface of the component to be cast, and the flange is fixed to the top surface of the template on both sides by bolting. Then a connecting nut is installed on the upper end of the embedded screw, and the embedded screw is passed through the reserved bolt hole on the flange, and the embedded screw is fixed to the designed position by tightening the connecting nut on the flange. However, when the exposed screw of the embedded screw on site is long, the traditional electric socket wrench will not be able to tighten the nut to the predetermined position due to the limited working length, and the use of an open-end wrench to tighten the connecting nut is inefficient. Therefore, how to conveniently and quickly tighten the nut along the connecting nut to the predetermined position to fix the embedded screw has become a difficult problem in actual on-site operations.

[0020] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0021] Embodiment 1: Figure 1 As shown, a socket wrench is characterized in that it includes a mounting barrel 4, a rotating shaft 2 and a mounting block 1, wherein the rotating shaft 2 is rotatably arranged in the mounting barrel 4, the mounting block 1 is arranged at one end of the rotating shaft 2, and a rotating handle 5 is arranged at the other end of the rotating shaft 2, and at least three tool clips 3 are arranged in a circumferential array on the mounting block 1. In this embodiment, the rotating shaft 2 and the mounting barrel 4 can rotate relative to each other, the mounting block 1 is welded to one end of the rotating shaft 2, and the rotating handle 5 is welded to the other end of the rotating shaft 2, so that the mounting barrel 4 is limited between the rotating handle 5 and the mounting block 1, the tool clip 3 is in the shape of an elongated strip, preferably three tool clips 3 are arranged, and a space for accommodating a nut is formed between the three tool clips 3, and the length of the tool clip 3 can be set according to the depth of the nut to be screwed into the screw rod, when in use, the tool clip 3 is clamped on the outside of the nut to be screwed, and the nut is clamped, and then one hand holds the mounting barrel 4, and the other hand holds one end of the rotating handle 5, and the rotating handle 5 can drive the nut to rotate, so that the nut is rotated to a predetermined position for easy use.

[0022] Furthermore, a rotating sleeve 6 is rotatably sleeved on the rotating handle 5, and a limit block 7 is provided on the rotating handle 5 to limit the position of the rotating sleeve 6. In this embodiment, the rotating handle 5 is L-shaped, and the rotating sleeve 6 is sleeved on the rotating handle 5, so that when the rotating sleeve 6 is held during use, the rotating sleeve 6 can rotate relative to the rotating handle 5 during rotation, which is convenient for operation.

[0023] Furthermore, the mounting block 1 is a regular hexagonal structure. In order to facilitate the installation of the tool clips 3 in this embodiment, the mounting block 1 is designed to be a regular hexagonal structure, so that it is convenient to set the three tool clips 3 on one side of the mounting block 1.
