Description

Clamp connector

This invention relates to a connecting rod, and more particularly to a clamp connecting rod.

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

In some situations, such as when the drive connector or fastener is not perpendicular to the device or mechanism, or when the connector or fastener is located in a narrow space, conventional straight-type drive tools output power at an angle, making it impossible to operate smoothly. Therefore, universal joints or tool extension rods are available for use with conventional drive tools to overcome these problems. While conventional universal joints or tool extension rods offer different angles or extensions, they also present inconveniences in maintaining and separating the drive component from the component being driven.

Therefore, it is necessary to provide a novel and progressive clamp connector to solve the above problems.

The main purpose of this invention is to provide a chuck connecting rod that can output power at an angle, stabilize and hold the workpiece to be driven, and remove the workpiece with appropriate force.

To achieve the above objectives, the present invention provides a chuck connector, comprising: a housing, a rigid material component, 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 assembly rotatably inserted into the head, a sliding sleeve disposed on the drive assembly, and a locking element, the drive assembly being rotatably connected to the second end, the drive assembly being for connection with a second tool, the second tool being for connection with a workpiece to be driven, a locking hole penetrating the peripheral wall of the drive assembly, and a magnetic element disposed on the side of the sliding sleeve away from the drive assembly. The sliding sleeve is movable relative to the drive assembly between a locked position and a released position. The latching member is disposed between the drive assembly and the sliding sleeve, and the latching member includes a latching portion located in the latching hole. When the sliding sleeve is in the locked position, the sliding sleeve radially limits the latching portion so that the latching portion protrudes into the drive assembly and latches against a limiting portion of the second tool. The workpiece to be driven, which is connected to the second tool, has a first distance from the magnet, and the limiting portion of the second tool has a second distance from the workpiece to be driven. The first distance is not greater than 1/5 of the second distance. When the sliding sleeve is in the released position, the sliding sleeve does not radially limit the latching portion so that the limiting portion of the second tool can disengage from the latching portion.

The following examples illustrate possible embodiments of the invention, but are not intended to limit the scope of protection sought by the invention. The prefixes "a" or "at least one" before the nouns mentioned herein are not intended to limit the quantity, and may also be "plural" depending on the requirements. Such variations in quantity are also within the scope of protection sought, as stated above.

Please refer to Figures 1 to 6, which show one embodiment of the present invention. The clamp rod 1 of the present invention includes a housing 10, a shaft 20 and a set of coupling components 30.

The housing 10 is a rigid material component, and the housing 10 includes a body 11 and a head 12 connected to the body 11 in a horizontal (e.g., but not limited to vertical) direction. The shaft 20 is rotatably inserted into the body 11, and 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 socket assembly 30 includes a drive kit 31 rotatably inserted into the head portion 12, a sliding sleeve 32 fitted onto the drive kit 31, and a locking member 33. The drive kit 31 is rotatably connected to the second end portion 22. The drive kit 31 is for insertion into a second tool (e.g., a screwdriver bit, drill bit, tool adapter, or other driving tool). The second tool 100 is for insertion into a workpiece 200 to be driven (e.g., a connector or fixed part). The drive assembly 31 has a slot 310 through its peripheral wall. The slide sleeve 32 has a magnet 321 on one side away from the drive assembly 31. The slide sleeve 32 can move between a locked position (Fig. 4) and a released position (Fig. 5) relative to the drive assembly 31. The latching member 33 is located between the drive assembly 31 and the slide sleeve 32. The latching member 33 includes a latching part 331 in the slot 310.

When the sliding sleeve 32 is in the locked position, the sliding sleeve 32 radially limits the locking part 331, causing the locking part 331 to protrude into the drive assembly 31 and lock onto a limiting part 101 of the second tool 100. The workpiece 200 to be driven and the magnet 321 connected to the second tool 100 have a first distance D1 (upward along the axis of the shaft 20), and the limiting part 101 of the second tool 100 and the workpiece 200 to be driven have a second distance D2. The first distance D1 is not greater than 1/5 of the second distance D2. When the sliding sleeve 32 is in the released position, the sliding sleeve 32 does not radially limit the locking part 331, allowing the limiting part 101 of the second tool 100 to disengage from the locking part 331. However, depending on different operational requirements, the first distance D1 may not be greater than 1/6, 1/7, 1/8, 1/9, or 1/10 of the second distance D2, or a range of the above values, or other smaller values.

In this way, the horizontally connected body 11 and head 12 can output power at an angle, and the magnet 321 maintains an appropriate distance from the workpiece 200 to be driven, which can stabilize and hold the workpiece 200 to be driven (e.g., a metal screw) and remove the workpiece 200 to be driven from the second tool 100 with appropriate force.

In this embodiment, the shell 10 is a rigid plastic component, which is simple to manufacture and can be molded into a variety of different structural forms. It also achieves a lightweight effect while maintaining the required structural strength. However, the shell 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 fastener 40 passes through the at least one lug 121 and is connected to the body 11. However, in other embodiments, the shell 10a may not include any lugs or slots (as shown in Figure 7). In detail, the outer peripheral wall of the body 11 is provided with two radially opposite slots 111. The head 12 includes two lugs 121, which are respectively inserted into the two slots 111. Two fasteners 40 pass through the two lugs 121 and are connected to the body 11, which helps to improve the alignment, connection strength and stability of the body 11 and the head 12, and makes it convenient and quick to install, disassemble, replace and maintain. The head 12 may also include two radially opposite through holes 122, and two cover pieces 50 are respectively detachably covered in the two through holes 122. The two through holes 122 can be used to connect an auxiliary handle to help hold the chuck rod 1. The two through holes 122 can also be used as a channel for, for example, lubricating substances to be introduced into the housing 10, making the operation convenient and fast.

Preferably, the drive assembly 31 is a magnetically attachable component, and the magnetic force of the magnet 321 enables the drive assembly 31 to also have a magnetic attraction effect. The drive assembly 31 may also include an elastic member 34, which is used to spring against the second tool 100. The latching member 33 is a ring-shaped spring set in the drive assembly 31. A radial flange 322 is protruding from the inner surface of the sliding sleeve 32. The latching member 33 is located between the radial flange 322 and the drive assembly 31. The latching member 33 and the magnet 321 are located on opposite sides of the radial flange 322. In detail, the latching part 331 further includes a horizontal segment 332 that passes through the latching hole 310 and a terminal segment 333 that extends from the horizontal segment 332. The terminal segment 333 is located outside the latching hole 310, which can stably keep the latching part 331 in the latching hole 310 and has good latching reliability.

The chuck connector 1 further includes a bearing 60, which is installed in the head 12 and fitted onto the drive assembly 31. Preferably, the slide sleeve 32 is a magnetic component, thereby enabling the slide sleeve 32 to also have a magnetic attraction effect, which helps to magnetically attract and stabilize the workpiece 200 to be driven.

The head portion 12 further includes a hinge hole 123, in which a bushing 70 is received and protrudes, providing good assembly strength for the bushing 70. The drive assembly 31 includes a hinge end 311, which is rotatably inserted into the hinge hole 123 and the bushing 70.

In this embodiment, the clamp rod 1 further includes a bushing 80, which is fitted onto the drive assembly 31 and abuts against the bearing 60 and the locking member 33. The sliding sleeve 32 is fitted onto the bushing 80. The shaft 20 defines an axial direction A, preferably extending through the bushing 70. 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. The drive assembly 31 is less prone to swaying and rotates stably, resulting in better power transmission and output.
