The present invention relates to a socket wrench.
Fasteners are used in many kinds of products to assemble components. Fasteners, such as screws, nuts, bolts or the like, are generally fastened or loosened by turning, and this is usually carried out by using socket wrench which is sleeved on the fastener and extended with an extension driving rod. The conventional socket wrenches are, for example, disclosed in TW M243305, TW M572814 and TW M576520.
However, the conventional socket wrench mentioned above needs to be operated in a specific direction in actual operation. Once the conventional socket wrench operates in an environment with too much debris or in a small space, its mobility and adaptability are insufficient, which causes troubles in disassembly and assembly operations.
The present invention is, therefore, arisen to obviate or at least mitigate the above-mentioned disadvantages.
The main object of the present invention is to provide a socket wrench which is swingable, can evenly transmit force, and is uneasy to be damaged and broken.
To achieve the above and other objects, a socket wrench is provided, including: a sleeving portion, including a sleeving hole disposed therethrough along a first direction; a connecting arm, extending from the sleeving portion in a direction lateral to the first direction; an operation rod; and a pin member, pinning the connecting arm and the operation rod in a direction non-perpendicular to the first direction so that the operation rod is rotatable about the pin member relative to the sleeving portion.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.
Please refer to
The sleeving portion 1 includes a sleeving hole 13 disposed therethrough along a first direction 6, and the sleeving hole 13 is hexagonal and configured for connection with a screw, nut, bolt or the like. The connecting arm 2 extends integrally from the sleeving portion 1 in a direction lateral to the first direction 6, which provides good structural strength. The pin member 4 pins the connecting arm 2 and the operation rod 3 in a direction non-perpendicular to the first direction 6 so that the operation rod 3 is rotatable about the pin member 4 relative to the sleeving portion 1.
In this embodiment, as shown in
Specifically, the connecting arm 2 includes two ear portions 21, the two ear portions 21 are arranged in interval and define an insertion space 22 therebetween, the operation rod 3 extends partially within the insertion space 22, each of the two ear portions 21 includes a through hole 23 and a threaded hole 24, the pin member 4 is disposed through the through hole 23 and the operation rod 3 and is screwed within the threaded hole 24, and thus the pin member 4 can transmit the force from the operation rod 3 evenly to the two ear portions 21.
Specifically, the connecting arm 2 further includes a main body 25, the main body 25 is connected between the two ear portions 21 and the sleeving portion 1, the operation rod 3 further includes a head portion 31 and a body portion 32 connected with each other, the head portion 31 extends within the insertion space 22, and the body portion 32 is located outside the insertion space 22 and has a diametric dimension larger than a distance between the two ear portions 21. As shown in
The pin member 4 includes a driving portion 41 and a threaded portion 42 corresponding to each other, the through hole 23 is located between the driving portion 41 and the threaded hole 24, the threaded portion 42 is disposed through the through hole 23 and is screwed within the threaded hole 24, and the driving portion 41 is partially engaged within the through hole 23. At least one of an end face of the driving portion 41 and an end face of the threaded portion 42 includes an assembling portion configured for driving the pin member 4 to rotate.
The driving portion 41 includes a first assembling portion 51, and the threaded portion 42 includes a second assembling portion 52. In a normal circumstance, the pin member 4 (not damaged or broken) can be screwed to or unscrewed from the two ear portions 21 by a driving tool engaged with the first assembling portion 51 or the second assembling portion 52 and rotating the pin member 4; when the pin member 4 is damaged or broken, the broken parts of the pin member 4 can be removed from the two ear portions 21, respectively, by a driving tool engaged with the first assembling portion 51 or the second assembling portion 52 and rotating the pin member 4.
Specifically, a diametric dimension of the driving portion 41 is larger than a diametric dimension of the threaded portion 42, and the first assembling portion 51, preferably, is of a structural configuration different from a structural configuration of the second assembling portion 52. Specifically, the first assembling portion 51 and the second assembling portion 52 are recesses, and the first assembling portion 51 has a cross-sectional area larger than a cross-sectional area of the second assembling portion 52, for sufficient connection portions of the threaded portion 42. In this embodiment, the first assembling portion 51 is a polygonal recess and the second assembling portion 52 is a linear recess, which is compatible with most common driving tools such as flathead screwdrivers or hex wrenches.
A first side portion 11 of the sleeving portion 1 and the driving portion 41 are located at the same side of the operation rod 3. Preferably, in the first direction 6, the first side portion 11 is protrusive beyond the connecting arm 2 and relatively higher than the driving portion 41, which is advantageous for operation and prevents collision of the driving portion 41. The first side portion 11 increases the entire length of the sleeving portion 1 in the first direction 6, which can be used for longer fasteners.
The sleeving portion 1 further includes a second side portion 12, the second side portion 12 is located at a side opposite to the first side portion 11, the second side portion 12 and the threaded portion 42 are located at the same side of the operation rod 3, the second side portion 12 and the connecting arm 2 are aligned with each other, and the end face of the threaded portion 42 is non-protrusive beyond the connecting arm 2 for avoiding collision.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
