Description

Technical Field

[0001] This utility model relates to a wrench, and more particularly to a wrench socket for high-load operations, belonging to the field of wrench socket technology. Background Technology

[0002] Wrenches are versatile tools used by repairmen. There are generally two main types of wrenches: fixed wrenches and adjustable wrenches. Fixed wrenches usually have a fixed head size, so it's common to carry a set of several wrenches of different sizes. Adjustable wrenches are more convenient than fixed wrenches because they can be used with a wider range of sizes;

[0003] However, traditional wrenches mostly have a fixed wrench head design, which makes it inconvenient to change the wrench head in actual use, resulting in certain limitations in use and making it unsuitable for high-load operation. Therefore, this utility model proposes a wrench sleeve with a replaceable wrench head that can be used for high-load operation. Utility Model Content

[0004] This invention provides a wrench sleeve for high-load operations, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a wrench socket for high-load operations, comprising a wrench end base, a wrench handle fixedly installed on one outer wall of the wrench end base, a reinforcing rod fixedly installed at the tail end of the wrench handle, and a hand handle fixedly installed on the outer wall of the reinforcing rod away from the wrench handle. A connecting crossbar is fixedly inserted into the hand handle, and the connecting crossbar is perpendicular to the hand handle. An inner groove is formed on the upper surface of the wrench end base, and at least five fixing holes are formed on the outer surface of the inner groove. These fixing holes are circumferentially distributed at equal intervals through the center point of the inner groove. A fixing plate is disposed within the inner groove, and assembly holes adapted to the fixing holes are formed on the outer surface of the fixing plate. A hexagonal prism is fixedly installed at the center of the upper surface of the fixing plate. The number of fixing holes and assembly holes are the same and correspond one-to-one.

[0007] Furthermore, in order to improve the multi-functional use of the wrench end seat, a horizontal surface is provided on the outer wall of the end of the wrench end seat away from the wrench handle, and four symmetrically distributed secondary fixing holes are provided on the horizontal surface.

[0008] Furthermore, to facilitate detachable connection, a connecting plate is provided at the front end of the wrench end seat, and secondary assembly holes adapted to the secondary fixing holes are provided at the four corners of the outer surface of the connecting plate.

[0009] Furthermore, in order to improve the performance, an internal hexagonal socket is fixedly installed at the center of the outer surface of the connecting plate, and an internal hexagonal groove is formed inside the internal hexagonal socket.

[0010] Furthermore, in order to improve the grip and anti-slip properties of the handheld rod and the connecting crossbar, a primary anti-slip sleeve is fixedly fitted on the outer surface of the handheld rod, and a secondary anti-slip sleeve is fixedly fitted on the outer walls of both sides of the connecting crossbar.

[0011] Furthermore, in order to describe the materials of the primary and secondary anti-slip sleeves, both the primary and secondary anti-slip sleeves are made of anti-slip rubber material.

[0012] Furthermore, in order to improve the anti-slip effect at the bottom of the handheld lever, a limiting component is fixedly installed on the outer wall of the tail end of the handheld lever, and the diameter of the limiting component is larger than the diameter of the handheld lever.

[0013] Compared with the prior art, the present invention provides the following beneficial effects:

[0014] The wrench socket of this utility model can be used for tightening and loosening of bolts or nuts of different types, and has a wide range of uses and is more practical.

[0015] When the internal hexagonal socket of this utility model is being disassembled or tightened, the user can hold both ends of the insertion crossbar to easily apply high-load rotational force through the insertion crossbar, making it convenient for hand-held load application. It can be used for high-load installation and disassembly of nuts, making it more convenient to use.

[0016] Meanwhile, both the hexagonal column and the internal hexagonal socket of this utility model are detachably mounted on the wrench end seat via bolts and holes. In actual use, multiple sets of hexagonal columns and internal hexagonal sockets of different models can be equipped, so that the hexagonal column and internal hexagonal socket can be easily replaced by bolt removal. This provides a dynamic and replaceable wrench head effect, allowing the wrench head to be dynamically changed according to the actual usage situation and environment, thereby meeting different usage needs and effectively reducing usage limitations.

In actual use, multiple sets of hexagonal columns 11 and internal hexagonal sockets 13 of different models can be equipped, so that the hexagonal column 11 and internal hexagonal socket 13 can be easily replaced by means of bolt disassembly. It has the effect of dynamic replacement of the wrench head. The wrench head can be dynamically replaced according to the actual use situation and use environment, thereby meeting different use needs and effectively reducing the limitation of use.

[0036] In summary, the technical solution of this utility model solves the technical problem in the background art that "traditional wrenches mostly have a fixed wrench head design, which makes it inconvenient to change the wrench head in actual use, has certain limitations in use, and is not conducive to high load application, thus having certain shortcomings in use".
