Abstract
Description
Technical Field
[0001] The utility model relates to the field of hardware components, in particular to a double-head connecting rod. Background Art
[0002] Screwdrivers are essential tools in our daily lives. Existing multi-purpose screwdriver sets include a handle, an extension bar, and a bit. Both the extension bar and the bit are interchangeable, with different extension bars having different interfaces that accommodate different types of bits. Consequently, a multi-purpose screwdriver set requires multiple extension bars, each capable of accommodating only one type of bit, resulting in low utilization. Summary of the Invention
[0003] The utility model mainly solves the above problems and provides a double-head connecting rod, so that one connecting rod can be installed with two types of cutting heads, thereby improving the utilization rate of the connecting rod.
[0004] The technical solution adopted by the utility model to solve its technical problem is a double-head connecting rod for being set on the screwdriver handle, comprising an integrally arranged mortise and tenon joint, a rod body and a sleeve joint, a first retaining spring steel ball being embedded in the surface of the mortise and tenon joint, and a limiting portion and a second retaining spring steel ball being provided in the middle of the rod body.
[0005] As a preferred embodiment of the above solution, the limiting portion includes two strip-shaped protrusions that are symmetrically arranged with respect to the axis of the rod body and extend axially.
[0006] As a preferred embodiment of the above solution, axially extending strip-shaped grooves are provided on both sides of the strip-shaped protrusion.
[0007] As a preferred embodiment of the above solution, the second retaining spring steel ball is in the middle of the arc surface between the two strip-shaped protrusions.
[0008] As a preferred solution of the above solution, the side surface of the middle part of the rod body is frosted.
[0009] As a preferred embodiment of the above solution, the tenon joint is in a prism shape.
[0010] As a preferred solution of the above solution, a prismatic socket hole is provided on the socket portion.
[0011] The utility model has the advantages that it can be used at both ends, cutter heads can be installed at both ends, and the utilization rate of the connecting rod is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solution of the present invention will be further described below with reference to the embodiments and the accompanying drawings.
[0015] Example:
[0016] The present embodiment provides a double-ended connecting rod for being arranged on a screwdriver handle, comprising an integrally arranged tenon joint 3, a rod body 2 and a sleeve joint 1, wherein the tenon joint 3 and the sleeve joint 1 are respectively located at both ends of the rod body. The rod body 2 is cylindrical, the tenon joint 3 is prismatic, a first retaining spring steel ball 4 is embedded on the surface of the tenon joint, and a prismatic sleeve hole is provided on the sleeve joint 1. A limiting portion and a second retaining spring steel ball 5 are provided in the middle of the rod body. The limiting portion comprises two strip-shaped protrusions 6 which are symmetrically arranged about the axis of the rod body and extend axially, and strip-shaped grooves 7 which extend axially are provided on both sides of the strip-shaped protrusions 6. A frosting is also provided on the side surface of the middle part of the rod body. The frosting setting can increase the friction between the rod body and the human hand, making it easier to pull out the double-ended connecting rod from the slot of the bolt cutter handle.
[0017] The double-ended connecting rod in this embodiment is designed to be used in conjunction with a screwdriver handle. During use, the end where the tenon joint 3 is located can be inserted into the slot of the screwdriver handle. The slot of the screwdriver handle is provided with a connecting rod limiting portion. The limiting portion in the middle of the rod body 2 cooperates with the connecting rod limiting portion to radially limit the double-ended connecting rod. At the same time, the second retaining spring steel ball abuts against the side wall of the slot to axially limit the double-ended connecting rod, thereby securing the rod body to the bolt cutter handle. A straight-shaped, cross-shaped, or other bolt bit can then be inserted into the prismatic socket hole of the sleeve portion for tightening bolts. Furthermore, the sleeve portion can also be inserted into the slot of the bolt cutter handle, similarly fixed by the limiting portion and the second retaining spring steel ball. A sleeve bit can then be mortised to the tenon joint 3 for tightening nuts and bolts, etc. This means that the double-ended connecting rod can be used at both ends, and a single connecting rod can accommodate two types of bits, thereby improving the utilization rate of the connecting rod.
[0018] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
