Description

Adjustable socket wrench

Technical Field

The utility model relates to the technical field of bolt construction tools, in particular to an adjustable socket wrench.

Background technique

A wrench is one of the commonly used repair tools in our lives. It is a hand tool that uses the principle of leverage to turn bolts, nuts and other threaded fasteners that hold the openings or holes of bolts or nuts. A wrench usually has a chuck at one or both ends of the handle. The chuck holds the opening or hole of the bolt or nut. The handle applies external force and rotates in the direction of thread rotation to turn the bolt or nut. Wrenches are usually made of carbon structural steel or alloy structural steel.

Due to the different sizes and applications of bolts and nuts, the types and forms of wrenches are also different. Common wrenches include box wrenches, socket wrenches, hexagonal wrenches, etc. For socket wrenches, the size and shape of its chuck are fixed. One socket wrench can only install and remove bolts or nuts of one size, resulting in a wide variety of wrenches needed for construction, which is very inconvenient to use.

Detailed ways

The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are 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.

In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating directions or positional relationships are based on the directions 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 direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

Example 1

As shown in Fig. 1-3, an adjustable socket wrench includes a fixed disk body 1, a four-corner interface 5 is provided at the top of the fixed disk body 1, and a handle 6 is detachably connected to the fixed disk body 1 through the four-corner interface 5. The four-corner interface 5 can effectively fix the handle 6 to prevent the handle 6 from rotating with the fixed disk body 1, ensuring that the staff can hold it stably and conveniently. The handle 6 can be manually driven or electrically driven. When electrically driven, a driving motor is provided at the end of the handle 6 away from the fixed disk body 1. The handle 6 is detachable for easy storage and for easy replacement of different handles 6 as needed.

A plurality of claws 4 are provided at the bottom end of the fixed disk body 1, and the inner wall of the claws 4 is provided with an end face that fits the shape of the end of the bolt or a thread corresponding to the bolt, which can clamp the bolt. A slide groove 7 is radially provided at the bottom of the fixed disk body 1, and the slide groove 7 corresponds to the claws 4 one by one, which can limit the claws 4 to move radially along the fixed disk body 1. Preferably, three claws 4 are provided, and the claws 4 are evenly distributed at the bottom of the fixed disk body 1 to ensure that the claws apply force evenly when clamping the bolt. The claws 4 move radially along the fixed disk body 1, which can change the distance between different claws 4, and then use bolts of various sizes and models, without the need to frequently change wrenches. The operation is simple and convenient, and the work intensity of the staff is reduced.

A rotating disk 3 is sleeved on the outside of the fixed disk body 1, and anti-slip grooves are provided on the outside of the rotating disk 3 to facilitate the staff to operate the rotating disk 3. The bottom of the rotating disk 3 is threadedly connected to the top of the claw 4. The bottom of the rotating disk 3 is slidably connected to the fixed disk body 1. The threaded locking direction of the top of the claw 4 is opposite to the locking direction of the clamping bolt inside the claw 4, ensuring that when the bolt is turned, the claw 4 is self-locked inward to achieve stable clamping of the bolt. A retaining spring 2 is provided at the connection between the top of the rotating disk 3 and the fixed disk body 1, which can provide resistance to the rotation of the rotating disk 3 to prevent the rotating disk 3 from excessively rotating to open the claw 4 and cause the bolt to slip. The outside of the claw 4 is stepped, and a retaining ring can be sleeved on the outside of the step after the position of the claw 4 is determined to fix the distance between the claws 4.

working principle:

The handle 6 is plugged into the fixed disk body 1, and the staff holds the handle 6 and rotates the rotating disk 3 to make the claws 4 move synchronously along the radial direction of the fixed disk body 1 until it adapts to the current bolt size. After loosening the rotating disk 3, the rotating disk 3 tends to the original position under the action of the clamping spring 2, thereby driving the claws 4 to tighten and stably clamp the bolt; then the handle 6 is rotated to realize the disassembly and assembly of the bolt.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
