Description

The present invention relates to a connecting rod that extends a rotating tool and is connected to a tool head.

The head part of a conventional manual tool or a tool driven by power is generally designed so that tool heads of different specifications can be exchanged. In order to extend the distance that the tool head can be operated, it is common to use a connecting rod, that is, the connecting rod has one end connected to the tool head portion and the other end connected to the tool head.

Please refer to FIG. 6 and FIG. In the conventional connecting rod, the connecting rod D has a connecting tool 60, the connecting tool 60 is provided with a connecting space 601 at one end, a regulating space 602 having a strip shape at the other end, and a pivoting tool 61 is provided. A pivot space 611 is provided at one end, a connecting column 612 is provided at the other end, a hole 613 is provided on the side of the pivot space 611, and a pivot hole is provided between the pivot space 611 and the connecting column 612. 614 is provided, the universal hole 615 penetrates from the pivot attachment hole 614 to the side of the connection column 612, one end having the restriction space 602 of the connection tool 60 is provided in the pivot attachment space 611, and the fixing pin 62 is connected to the hole 613. They are combined and inserted into the restriction space 602. The presser rod 63 is provided with a locking portion 631 at one end, and after the spring 64 is disposed, the presser rod 63 is pivotally attached to the pivot hole 614 via the pivot attachment space 611, and the presser rod 63 corresponds to the universal hole 615. A sink groove 632 is provided, and a latch 65 is provided in the universal hole 615.

Next, the operation of the connecting rod D will be described. First, when the tool head B and the connecting column 612 are coupled to each other, as shown in FIGS. 7 and 8, the presser rod 63 moves to the connecting column 612 by pressing the pivoting tool 61 against the connecting tool 60. Then, the locking element 65 falls into the sinking groove 632 and becomes lower than the surface of the connecting column 612, and the tool head B can be coupled to the connecting column 612. When the pressing force is lost, the pressing rod 63 is returned to its original position by the spring 64, and the locking element 65 is lifted on the surface of the connecting column 612 to lock the tool head B.

However, this has the following drawbacks.
(1) Since the connecting tool 60 and the pivoting tool 61 are connected by inserting the fixing pin 62 into the restriction space 602, the connecting tool 60 and the pivoting tool 61 cannot be reliably positioned, and noise due to a collision occurs during the process of use. .

(2) The connecting rod D regulates the connecting tool 60 and the pivoting tool 61 in addition to the connecting tool 60, the pivoting tool 61, the presser rod 63, the spring 64, and the latch 65. Therefore, since it is necessary to use the fixing pin 62, the structure is complicated, and the installation of the fixing pin 62 and the localization of the restriction space 602 are not easy. .
