Description

[Technical Field]

[0001] This invention relates to a connecting rod, and more particularly to a clamp connecting rod. [Previous Technology]

[0002] In many fields, such as the assembly, disassembly, connection, and fastening of devices or mechanisms, it is often necessary to use driving tools (such as electric, pneumatic, and manual tools) to drive the driving components (such as screwdriver bits, drill bits, tool adapters, etc.) to rotate, so as to connect the connecting parts or fasteners to the device or mechanism.

[0003] In some cases, such as when the orientation of the drive connector or fastener is not perpendicular to the device or mechanism, or when the connector or fastener is located in a confined space, a conventionally straight drive tool will output power at an angle, making it difficult to perform operations smoothly. Therefore, universal joints or tool extension rods are available for use with conventional drive tools to overcome the aforementioned operational problems. While conventional universal joints or tool extension rods can provide different angles or extensions, they also present inconveniences in maintaining and separating the drive component from the assembly structure.

[0004] Therefore, it is necessary to provide a novel and progressive clamping rod to solve the above-mentioned problems. [Summary of the Invention]

[0005] The main objective of this invention is to provide a clamping rod that can turn the power output at an angle and facilitate the removal of the drive tool.

[0006] To achieve the above objective, the present invention provides a clamping rod, comprising: a housing including a body and a head laterally connected to the body; a shaft rotatably inserted into the body, including a first end and a second end opposite to each other, the first end being for connection with a first tool; and a connecting assembly including a drive kit rotatably inserted into the head, and a detachable outer sleeve fitted outside the drive kit, the drive kit being rotatably connected to the second end, the drive kit being for connection with a second tool, and the outer sleeve having at least one first magnet on the side away from the drive kit.

Implementation Method

[0007] The following examples illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention. The words "a" or "at least one" preceding the terms mentioned herein are not intended to limit the quantity. Depending on the requirements, there may also be "multiple" items. This variation in quantity is also within the scope of protection, as will be stated in advance.

[0008] Please refer to Figures 1 to 6, which show one embodiment of the present invention. The clamp connecting rod 1 of the present invention includes a housing 10, a shaft 20 and a connecting assembly 30.

[0009] The housing 10 includes a body 11 and a head 12 connected laterally (e.g., but not limited to vertically) to the body 11. A shaft 20 is rotatably inserted into the body 11. The shaft 20 includes a first end 21 and a second end 22 opposite to each other. The first end 21 is for connection with a first tool (e.g., electric, pneumatic, manual, etc.). The sleeve assembly 30 includes a drive kit 31 rotatably inserted into the head 12 and an outer sleeve 32 detachably sleeved on the drive kit 31. The drive kit 31 is rotatably connected to the second end 22. The drive kit 31 is for connection with a second tool (e.g., screwdriver bit, drill bit, tool adapter, etc.). The outer sleeve 32 has at least one first magnet 321 on the side away from the drive kit 31. In this way, the horizontally connected body 11 and head 12 can output power at an angle, and the outer kit 32 is detachable, so that the second tool inserted in the drive kit 31 can be easily removed after the outer kit 32 is detached.

[0010] In this embodiment, the housing 10 is a rigid plastic component, which is simple to manufacture and can be molded into a variety of different structural forms. It also has a lightweight effect while maintaining the required structural strength. However, the housing 10 can also be made of other suitable materials. The outer peripheral wall of the body 11 is provided with at least one slot 111. The head 12 includes at least one lug 121, which is inserted into the at least one slot 111. At least one fastening member 40 passes through the at least one lug 121 and is connected to the body 11. Specifically, the outer peripheral wall of the body 11 is provided with two radially opposing slots 111. The head 12 includes two lugs 121, which are respectively inserted into the two slots 111. Two fastening members 40 pass through the two lugs 121 and are connected to the body 11. This facilitates the alignment, connection strength, and stability of the body 11 and the head 12, and makes assembly, disassembly, replacement, and maintenance convenient and quick. The head 12 may further include two radially opposite through holes 122, and two cover pieces 50 are detachably provided on the through holes 122. The through holes 122 can be used to assemble auxiliary handles to help hold the chuck connecting rod 1, and the through holes 122 can also serve as channels for, for example, lubricating substances to be introduced into the housing 10, making operation convenient and fast.

[0011] Preferably, the drive assembly 31 is a magnetic component, wherein the outer assembly 32 and the drive assembly 31 are magnetically attracted and positioned by the magnetic force of the at least one first magnet 321. The outer assembly 32 is provided with two first magnets 321, which can provide sufficient magnetic force. The at least one first magnet 321 is relatively close to the end of the second tool, which can make the second tool magnetic, thereby more stably holding the component to be driven (e.g., a metal screw).

[0012] The clamp connecting rod 1 further includes a bearing 60, which is installed in the head 12 and sleeved on the drive assembly 31. Preferably, the outer assembly 32 is a magnetically conductive member, the bearing 60 and the outer assembly 32 are axially abutted, and the at least one first magnet 321 is axially abutted with the drive assembly 31, thereby providing appropriate magnetic attraction between the outer assembly 32 and the drive assembly 31, so that the outer assembly 32 can be stably held and easily detached.

[0013] The head 12 further includes a pivot hole 123, in which a bushing 70 is received and does not protrude, providing good assembly strength for the bushing 70. The drive assembly 31 includes a pivot end 311, which is rotatably inserted into the pivot hole 123 and the bushing 70. Specifically, the pivot end 311 includes a small-diameter section 312 and a large-diameter section 313 connected together. The small-diameter section 312 is inserted into the bushing 70, and a portion of the large-diameter section 313 is inserted into the pivot hole 123 and axially abuts against the bushing 70, providing a larger and better support structure and strength for the pivot end 311. The bushing 70 and the large-diameter section 313 have equal outer diameters, so that the outer circumferential surfaces of the bushing 70 and the large-diameter section 313 are flush, which helps the drive assembly 31 to rotate stably.

[0014] Preferably, the socket assembly 30 further includes a magnetic attraction assembly 33, and the drive assembly 31 further includes an axial through hole 314 and a flange 315 extending radially from one end of the axial through hole 314. The magnetic attraction assembly 33 is embedded in the axial through hole 314 and axially abuts against the flange 315. In detail, the magnetic attraction assembly 33 includes an insert 331 and a second magnetic element 332. The outer peripheral surface of the insert 331 includes a toothed section 333 and a smooth section 334. The toothed section 333 is embedded and fastened in the axial through hole 314, and the smooth section 334 abuts axially against the flange 315. The insert 331 further includes two non-connected recesses 335, which are respectively located at two opposite axial ends of the insert 331. The second magnetic element 332 is embedded in one of the recesses 335 and is used to magnetically attract the second tool. The second magnet 332 can more stably hold the second tool inserted in the drive kit 31.

[0015] In this embodiment, the shaft 20 defines an axial direction A, preferably extending through the drive assembly 31. Thus, the drive assembly 31 can be more effectively held between the second end 22 of the shaft 20 and the inner wall of the head 12, and the drive assembly 31 is less prone to swaying and rotates stably, resulting in better power transmission and output effects.

[0016] In the embodiment shown in Figures 7 and 8, one end of the drive assembly 31a is provided with a magnetically connected magnetic attraction mechanism 316, which is embedded in the head 12 of the housing 10. Specifically, the magnetic attraction mechanism 316 includes a sleeve 317 embedded in the head 12 of the housing 10 and a magnetic element 318 housed in the sleeve 317. The sleeve 317 has a radially inner flange 319 at the end opposite to the second tool, which blocks the magnetic element 318. This shortens the axial dimension of the head 12 of the housing 10. Furthermore, the magnetic attraction mechanism 316 can further magnetically attract the second tool inserted into the drive assembly 31a, thus more stably holding the second tool.
