[0003] To address the shortcomings of existing technologies, this utility model provides a wrench that facilitates the installation and removal of screws.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a wrench for easy screw installation and removal, comprising a fixed post, an installation head fixedly mounted on one end of the fixed post, a plurality of receiving grooves being provided on the installation head, the plurality of receiving grooves being equally spaced along the circumference of the installation head, a rotating rod being rotatably mounted on each receiving groove, and one or more loading and unloading holes being provided on one end of each rotating rod, each loading and unloading hole being of a different size.
[0005] Preferably, a plurality of elastic telescopic rods are fixedly installed on one end of the fixed column, and the plurality of elastic telescopic rods are arranged in a one-to-one correspondence with a plurality of rotating rods. The lowest point of the movable end of the elastic telescopic rod is at the same height as the upper surface of the mounting head, and the other end of the rotating rod is provided with an insertion hole that is adapted to the movable end of the elastic telescopic rod.
[0006] Preferably, a handle is fixedly installed on the other end of the fixing post.
[0007] Beneficial effects
[0008] Compared with the prior art, this utility model provides a wrench that facilitates the installation and removal of screws, and has the following beneficial effects:
[0009] An installation head is fixedly installed on one end of a fixed column. Multiple rotating rods are rotatably installed on the installation head. The multiple rotating rods are evenly distributed on the circumference of the installation head. Each rotating rod has one or more loading and unloading holes at one end. The size of each loading and unloading hole is different. This wrench can load and unload screws of various sizes. It is quick and convenient to use and has a simple structure.
[0010] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings. The specific implementation methods of this utility model are given in detail in the following embodiments and their accompanying drawings. Attached Figure Description

[0015] In the diagram: 1. Fixed post; 2. Rotating rod; 3. Mounting head; 4. Flexible telescopic rod; 5. Receiving groove; 6. Insertion hole; 7. Handle. Detailed Implementation
[0016] The following combination Figures 1 to 3 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.
[0017] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0019] Please combine Figures 1 to 3As shown, this utility model provides a wrench for easy screw installation and removal. The wrench includes a fixed post 1, an installation head 3 fixedly mounted on one end of the fixed post 1, and a handle 7 fixedly mounted on the other end of the fixed post 1. The installation head 3 has multiple receiving slots 5, which are evenly distributed around the circumference of the installation head 3. Each receiving slot 5 has a rotating rod 2 rotatably mounted on it. Each rotating rod 2 has one or more loading and unloading holes at one end, and each loading and unloading hole is of a different size. When installing or removing screws, different loading and unloading holes can be selected according to the size of the screw, so that the rotating rod 2 to be used is rotated to a horizontal state. At this time, the rotating rod 2 is perpendicular to the fixed post 1. The operator can then hold the handle 7 to rotate the fixed post 1.
[0020] Since the rotating rod 2 is freely rotatable, it is inconvenient for workers to operate when installing or removing screws. Therefore, multiple elastic telescopic rods 4 are fixedly installed on one end of the fixed column 1. The multiple elastic telescopic rods 4 are set one-to-one with the multiple rotating rods 2. The lowest point of the movable end of the elastic telescopic rod 4 is at the same height as the upper surface of the mounting head 3. The other end of the rotating rod 2 is provided with a socket 6 that matches the movable end of the elastic telescopic rod 4. When the rotating rod 2 is rotated to a horizontal state, the movable end of the elastic telescopic rod 4 is extended. At this time, the movable end of the elastic telescopic rod 4 is attached to the upper surface of the rotating rod 2, and the elastic telescopic rod 4 restricts the normal rotation of the rotating rod 2. The worker can operate more quickly and conveniently when installing or removing screws. When the rotating rod 2 needs to be rotated to a vertical state, the worker presses the movable end of the elastic telescopic rod 4. After the movable end of the elastic telescopic rod 4 retracts, the rotating rod 2 can rotate upward. When the rotating rod 2 is rotated to a vertical state, the movable end of the elastic telescopic rod 4 is inserted into the socket 6, so that the rotating rod 2 is kept in a vertical state. It is also more convenient to carry the wrench.
[0021] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
