Description

Palm device

The creation is a device for palm tools, which refers to a palm tool with an extended force-applying arm, and has the grip comfort of the palm tool and the design of the force-applying arm, which is quite practical.

For example, the structure of China's new patent application No. 88221205, "The improvement of the structure of the palm-shaped ratchet wrench" is the palm of the hand. The reason why it is so called is that the palm of the hand is pressed against the top of the palm. , in turn driving or turning the workpiece; as mentioned in the above case, such a palm tool is quite practical, and is convenient to carry and use, but the force exerted on it may be uncomfortable or uncomfortable. The drawback is that there is a patented structure, but the structure is to use the added rod body to match the control hole of the body as an extended force arm. In this way, not only the rod body is more inconvenient to carry, but also easier. Destroy the structure and endurance of the body.

The creators of this case are based on the knowledge and experience of designing ratchet tools for many years, actively working on development, research and improvement, and launching a “device for palm tools”, which can provide more stable support and improve the above-mentioned shortcomings.

The present invention is a device for a palm tool, which is mainly a ratchet body and an extension member pivoted thereon, wherein the top side and the lower side of the ratchet body are provided a fastening portion and a ratchet driving device, wherein the fastening portion is formed with a curved portion, and the bottom portion of the curved portion is provided with a top rib, and a side of the ratchet body is provided with a pivoting block, and a pivot hole is disposed on the pivoting block The extension member includes a fastening seat and a connecting buckle. The fastening seat is provided with a fastening groove in the middle of the fastening seat, and can be fastened to the fastening portion of the ratchet body, and the fastening seat is also provided with a corresponding buckle. The surface of the joint is folded and formed on the periphery of the seat and formed with a grip block for gripping by the user. The buckle rod can be buckled into the pivot hole of the pivot block, and the extension member is disposed relative to the top rib of the ratchet body There is a corresponding concave shoulder portion, so that when the extension member is buckled into the ratchet body, the concave shoulder portion can also be buckled into the top rib, and the buckle seat can be engaged with the top rib, thereby achieving the utility of the present invention.

The present invention is a device for a palm tool, as shown in the first to second figures, which is mainly a ratchet body (1) and an extension member (2) pivoted thereon, wherein: the ratchet body (1) The top side and the lower side are provided with a fastening portion (11) and a ratchet driving device (12), and the ratchet driving device (12) has a function of driving a workpiece (that is, a conventionally known ratchet driving member, Not in the narrative), and The fastening portion (11) is formed with a curved portion (111), and the bottom portion of the curved portion (111) is provided with a top rib (112), and a pivoting block (13) is disposed on one side of the ratchet body (1), and A pivot hole (131) is disposed on the pivoting block (13); the extension member (2) includes a fastening seat (21) and a connecting buckle (22), wherein the fastening seat (21) is disposed in the middle There is a fastening groove (211), which can be fastened to the fastening portion (11) of the ratchet body (1), and the fastening seat (21) is also provided with a corresponding fastening surface (212), and can be buckled When the seat (21) is fastened to the ratchet body (1), the engaging surface (212) can be simultaneously engaged with the curved portion (111) of the engaging portion (11), and the area of the fastening can be increased. And a clamping force in the pressing direction (longitudinal direction); additionally, a periphery of the fastening seat (21) is formed with a holding block (213) for the user to use, and the fastening rod (22) can be buckled The pivoting hole (131) of the pivoting block (13) is such that the fastening seat (21) of the extension member (2) is not disengaged from the pivoting block (13) of the ratchet body (1), and the extension member (2) is opposite A corresponding concave shoulder portion (214) is disposed at a position of the top rib (112) of the ratchet body (1) such that the extension member (2) has a concave shoulder portion (214) when being inserted into the ratchet body (1). The top rib (112) can also be buckled, and the buckle seat (21) is engaged with the top rib (112), thereby achieving the locking of the rotation direction (lateral direction); please refer to the third A diagram and the third B diagram. As shown in the fourth figure, the feature of the present invention is that the extension member (2) is fastened into the pivot hole (131) of the pivoting block (13) by the fastener (22), so that the extension member (2) is opposite to The ratchet body (1) has the function of pivoting without disengagement; and when the extension member (2) is flipped over the ratchet body (1), the fastening seat (21) of the extension member (2) can be buckled into the ratchet body ( 1) on the fastening portion (11), and because the fastening surface (212) can be simultaneously engaged It is inserted into the curved portion (111) of the engaging portion (11) to increase the fastening area and the clamping force (longitudinal direction) of the clamping force, and additionally by the concave portion of the extending member (2) (214) ) can also be buckled into the top rib (112), and the snap seat (21) is engaged with the top rib (112), thereby achieving the locking in the direction of rotation (lateral), so that it is stuck in either the vertical or the horizontal direction. Live, and cooperate with the periphery of the buckle seat (21) and form a grip block (213) to achieve a stable grip to use the palm tool; in addition, please refer to the fifth figure, and when the force arm When it is necessary to increase, it only has to flip the extension member (2). At this time, because the pivoting of the pivot rod (22), the extension member (2) can be turned over from the ratchet body (1), and the extension arm can be extended. The structure is functional and there is no need to add additional equipment or design.

The above is only a preferred embodiment for explaining the present invention, and is not intended to limit the present invention in any way, so that any modifications or changes to the present invention made under the same creative spirit are , for other types that can be implemented and have the same effect, should still be included in the scope of the proposed protection.
