Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of socket wrench equipment, specifically a socket wrench assembly. Background Technology
[0002] A socket wrench is generally called a socket. It consists of multiple sockets with hexagonal or dodecagonal holes, along with handles, extension rods, and other accessories. It is particularly suitable for tightening bolts or nuts in very confined or deeply recessed areas. A socket wrench is used when the end of the nut or bolt is completely below the surface being connected, and the diameter of the recess cannot be used with an open-end wrench, adjustable wrench, or box wrench. Additionally, it is used when space is limited by the bolt.
[0003] Most existing wrenches are single-type wrenches, which can only be used for one type of bolt. Therefore, in order to use wrenches for other bolt types, it is necessary to change the socket type. Moreover, the length of the socket is limited, making it impossible to operate in environments with limited space. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a socket wrench assembly that solves the problems of a limited range of compatible bolt types and inability to be used in confined spaces.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a socket wrench assembly, including a transmission rod, a socket fixedly installed at the front end of the transmission rod, multiple springs fixedly installed inside the socket, a rubber ring sleeved on the outside of the spring, a steel rod fixedly installed at the lower end of the spring, a placement groove opened inside the transmission rod, and an extension rod movably installed inside the placement groove.
[0006] As a preferred embodiment of this utility model, a locking block is fixedly installed on the lower end face of the front end of the transmission rod, and an annular groove is fixedly installed on the upper end face of the front end of the transmission rod. The interior of the locking block is connected to the transmission rod.
[0007] As a preferred embodiment of this utility model, a locking pin is fixedly installed at the upper end of the sleeve, and a first threaded pin is fixedly installed at the top end of the locking pin.
[0008] As a preferred embodiment of this utility model, the first threaded post penetrates the interior of the transmission rod, and a fastening ring is movably connected to the outside of the first threaded post. Fixing plates are fixedly installed on both sides of the upper end of the fastening ring.
[0009] As a preferred embodiment of this utility model, one end of the extension rod is fixedly installed with an insert rod, and one end of the insert rod is fixedly installed with a second threaded post.
[0010] As a preferred embodiment of this utility model, a reinforcing block is fixedly installed at the other end of the extension rod, and a connecting groove is provided inside the reinforcing block.
[0011] Compared with the prior art, this utility model provides a socket wrench assembly, which has the following beneficial effects:
[0012] This utility model features a socket wrench suitable for various bolt types. The socket is fixedly connected to a transmission rod. A square post at the upper end of the socket is fitted inside the front end of the transmission rod. A threaded rod is fixedly installed at the top of the square post and connects to a threaded ring at the upper end of the transmission rod. Rotating the threaded ring tightens the connection between the socket and the transmission rod. Multiple steel rods are movably installed inside the socket, with a spring fixedly installed at one end. A rubber ring is fitted around the spring. During use, the bolt presses against the internal steel rods, causing the side of the pressed steel rod to engage with the bolt. This engagement is achieved through friction. Rotating the transmission rod then causes the bolt to rotate. An extension rod is placed inside the transmission rod. When space is limited, the extension rod can be connected to the transmission rod to increase the usable length and facilitate use. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 In this embodiment: a socket wrench assembly includes a transmission rod 1, with a socket 3 fixedly installed at the front end of the transmission rod 1 for disassembling bolts during use. Multiple springs 16 are fixedly installed inside the socket 3, utilizing elasticity. Rubber rings 15 are fitted around the outside of the springs 16 to increase their stability during use. A steel rod 17 is fixedly installed at the lower end of the springs 16 to increase their strength during use. A placement groove 2 is provided inside the transmission rod 1, and an extension rod 10 is movably installed inside the placement groove 2 to increase the convenience of the wrench during use, enabling it to be used in confined spaces.
[0020] In this embodiment, a locking block 4 is fixedly installed on the lower end face of the front end of the transmission rod 1 to increase the stability of the sleeve 3 during installation. An annular groove 5 is fixedly installed on the upper end face of the front end of the transmission rod 1. The interior of the locking block 4 is connected to the transmission rod 1 to increase the stability during connection. A locking post 8 is fixedly installed on the upper end of the sleeve 3. A first threaded post 9 is fixedly installed on the top of the locking post 8 to facilitate movable connection. The first threaded post 9 penetrates the interior of the transmission rod 1 to increase the tightness during connection. A fastening ring 6 is movably connected to the outside of the first threaded post 9. Fixing plates 7 are fixedly installed on both sides of the upper end of the fastening ring 6 to facilitate manual fastening operation.
[0021] In this embodiment, one end of the extension rod 10 is fixedly installed with an insert rod 11 to increase the stability during installation. One end of the insert rod 11 is fixedly installed with a second threaded post 12, which is connected by threaded rotation. The other end of the extension rod 10 is fixedly installed with a reinforcing block 13 to enhance the strength during use. The reinforcing block 13 has a connecting groove 14 inside to facilitate connection with the first threaded post 9 at the top of the sleeve 3.
[0022] The working principle and usage process of this utility model are as follows: When using the device, the operator places the sleeve 3 on the upper end of the bolt. The bolt compresses the steel rod 17 inside the sleeve 3. A spring 16 is fixedly installed on the upper end of the steel rod 17, and a rubber ring 15 is fixedly installed on the outside of the spring 16 to increase the stability of the spring 16 during use. Multiple steel rods 17 are installed inside the sleeve 3. The steel rods 17 inside the sleeve 3 are compressed according to the size of the bolt. After being compressed, the bolt enters the interior of the sleeve 3. The uncompressed steel rods 17 contact the side of the bolt, and the bolt rotates due to friction. When space is limited during operation, the extension rod 10 is taken out from the inside of the placement groove 2. The insert rod 11 is inserted into the inside of the locking block 4. The second threaded post 12 at the top of the locking block 4 is connected to the fastening ring 6 inside the ring groove 5. The other end of the extension rod 10 is fastened to the first threaded post 9 at the top of the sleeve 3, increasing the convenience of use.
[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
