Description

Double-head ratchet tool

The present invention relates to hand tools, and in particular to a double-headed ratchet tool.

Ratchet tools allow users to rotate fasteners such as screws, bolts, and nuts by repeatedly moving their hands back and forth within a limited space. With a ratchet mechanism as its core component, ratchet tools can rotate fasteners in the preset drive direction, but not in the opposite direction. This can significantly reduce the required operating space and eliminate the need to frequently change hand position to rotate, effectively improving work efficiency.

However, traditional ratchet tools often feature a single head with a ratchet mechanism fixed to one end of the handle. This restricts their flexibility and deformability, and their operational versatility is limited, making them inadequate for use in various environments.

Therefore, it is necessary to provide a novel and advanced double-head ratchet tool to solve the above-mentioned problems.

The primary purpose of the present invention is to provide a double-headed ratchet tool having two drive heads with different ratchet rotation directions and configurations disposed on opposite sides of the tool body. Furthermore, the two drive heads have different swing directions, thereby enabling the tool to accommodate a variety of different angles and configurations of use.

To achieve the above objectives, the present invention provides a double-head ratchet tool, comprising: a body, a first driving head, and a second driving head. The main body includes a first end and a second end relative to each other; the first driving head includes a first base and a first ratchet, the first base is rotatably arranged on the first end with a first swing axis as the axis, and the first ratchet is rotatably arranged on the base with a first rotating axis as the center, and the first rotating axis and the first swing axis are in an intersecting configuration; the second driving head includes a second base and a second ratchet, the second base is rotatably arranged on the second end with a second swing axis as the axis, the second swing axis and the first swing axis are in a transverse configuration, and the second ratchet is rotatably arranged on the second base with a second rotating axis as the center, and the second rotating axis and the second swing axis are in a non-intersecting configuration.

The following examples are merely illustrative of possible implementations of the present invention, and are not intended to limit the scope of protection of the present invention. The words "one" or "at least one" preceding the terms mentioned herein do not limit the quantity, and the number may be "plural" as needed. Such variations in quantity also fall within the scope of protection, and are therefore described above.

Please refer to Figures 1 to 10, which show an embodiment of the present invention. The double-head ratchet tool of the present invention includes: a body 1, a first driving head 2 and a second driving head 3.

The main body 1 includes a first end 11 and a second end 12. The first drive head 2 includes a first base 21 and a first ratchet 22. The first base 21 is pivotally mounted on the first end 11 about a first swing axis 81. The first ratchet 22 is rotatably mounted on the first base 21 about a first rotation axis 91. The first rotation axis 91 and the first swing axis 81 are intersecting. The second drive head 3 includes a second base 31 and a second ratchet 32. The second base 31 is rotatably mounted on the second end portion 12 around a second swing shaft 82. The second swing shaft 82 is transversely arranged with respect to the first swing shaft 81. The second ratchet 32 is rotatably mounted on the second base 31 around a second rotating shaft 92. The second rotating shaft 92 and the second swing shaft 82 are non-intersecting.

As can be seen from the above, the swinging directions of the first drive head 2 and the second drive head 3 are completely different, and can be used in various different swinging angles. In addition, the different rotation directions of the first ratchet 22 and the second ratchet 32 can further produce more various usage combinations and can be fully applied to various different environments.

Preferably, one of the first end portion 11 and the second end portion 12 is recessed with an assembly space 121, and the outer contour of the other includes two flat surfaces 111. One of the first base 21 and the second base 31 is movably inserted into the assembly space 121, and the other is movably clamped against the two flat surfaces 111. The first end portion 11 and the second end portion 12 are respectively assembled with the first base 21 and the second base 31 via different structures, one concave and one convex. This not only makes it easier for the assembler to quickly identify the difference, but also ensures that the main body 1 retains a certain structural strength.

In this embodiment, the first drive head 2 further includes a first pivot 23, which extends along the first swing axis 81 to connect the first base 21 and the first end 11. The second drive head 3 further includes a second pivot 33, which extends along the second swing axis 82 to connect the second base 31 and the second end 12. Furthermore, as shown in FIG3 , when the second rotation axis 92 and the first swing axis 81 are parallel to each other, the second drive head 3 does not extend beyond the first drive head 2 in the direction of extension of the first swing axis 81. The structural differences of different thicknesses and sizes provide users with a variety of application options.

Furthermore, the first drive head 2 further includes a first adapter 5, which is mounted on the first ratchet 22 with the first rotation axis 91 as its center, in a co-rotating relationship. The first adapter 5 is configured to engage with a rotating member (e.g., a sleeve). In this embodiment, the first adapter 5 includes a first body 51 and a first head 52, which are connected to each other. The first body 51 is embedded in the first base 21 and connected to the first ratchet 22. The first head 52 protrudes from the first base 21. The first base 21 ensures that the first ratchet 22 rotates smoothly without interference from external objects.

Furthermore, the double-ended ratchet tool further includes an insert rod 4 and a second adapter 6. The insert rod 4 is removably inserted into the second ratchet 32 for co-rotational engagement, and the second adapter 6 is mounted on the insert rod 4. Two exemplary, but not limited to, usage scenarios are provided for this embodiment. Aspect 1: Like using an L-bar, the insert rod 4 allows the second adapter 6 to penetrate deep into a space and engage the object to be rotated. The user then holds the main body 1 and drives the insert rod 4 through the second ratchet 32. Aspect 2: Like using a T-bar, the first adapter 5 engages the object to be rotated, and the user holds the insert rod 4 to rotate the main body 1.

Preferably, the double-headed ratchet tool further includes a third adapter 7. The second adapter 6 and the third adapter 7 are arranged on opposite sides of the insert rod 4. The size of the second adapter 6 is different from that of the third adapter 7. In this way, a variety of sizes can be provided for users to choose.

Another preferred embodiment is that at least one of the second adapter 6 and the third adapter 7 is detachably assembled to the insertion rod 4, and the user can replace it with a different size, different style or other good product according to different needs.

In another preferred embodiment, the second adapter 6 and the third adapter 7 respectively interfere with the second driving head 3 at the second rotating shaft 92 to effectively prevent the insertion rod 4 from being separated from the second ratchet 32.

More specifically, the second adapter 6 includes a second baffle 61, a second body 62, a second head 63, and a second socket 64. The second head 63 coaxially protrudes from the second body 62. The second baffle 61 protrudes laterally from a side of the second body 62 away from the second head 63. The second baffle 61 and the second ratchet 32 prevent interference with each other. The second socket 64 coaxially extends from a side of the second body 62 away from the second head 63 toward the second head 63. Similarly, the third adapter 7 includes a third baffle 71, a third body 72, a third head 73, and a third socket 74. The third head 73 coaxially protrudes from the third body 72. The third baffle 71 protrudes laterally from one side of the third body 72 away from the third head 73. The third baffle 71 and the second ratchet 32 prevent interference with each other. The third socket 74 coaxially extends from one side of the third body 72 away from the third head 73 toward the third head 73.

More specifically, the first head portion 52, the second head portion 63, and the third head portion 73 have different sizes, providing a wide variety of sizes for users to choose from. The plunger 4 includes a shaft 41, a second set of joints 42, and a third set of joints 43. The shaft 41 extends in a straight line. The second set of joints 42 and the third set of joints 43 protrude axially from opposite end surfaces of the shaft 41. The second set of joints 42 is removably connected to the second receptacle 64, and the third set of joints 43 is removably connected to the third receptacle 74.

It is worth mentioning that the second adapter 6 and the third adapter 7 can be detachably connected to the insertion rod 4 and the second ratchet 32 respectively, thereby providing users with more diverse usage combinations; wherein, the second body 62 and the third body 72 have the same size, and the second body 62 and the third body 72 can be respectively connected to the second ratchet 32.

Preferably, the outer contours of the second body 62, the outer contours of the third body 72, and the outer contours of the insertion rod 4 are polygonal, so as to facilitate cooperation with other tool structures and rotation.
