Description

wrench

This creation relates to the field of hand tools, in particular to a wrench that can be selected for different sizes or sizes of actuators.

There are a wide variety of known wrenches, such as socket wrenches, open end wrenches and plum wrenches.

A conventional plum wrench has a grip and at least one actuating portion, the actuating portion being annular, which is integrally formed with the end of the grip. There is a hole in the center of the actuating part, and the shape of the hole is nothing more than a hexagonal or a dodecagonal shape, which is enough to cover a screwing piece to perform locking or unscrewing work.

Since the size of the hexagonal hole or the twelve-corner hole is the same, the actuator of the Torx wrench can only be used for one type of screw connector, and a set of Torx wrench symbols must be prepared for use. There are usually ten or twenty wrenches in each group, which is not only time-consuming to search, but also increases the load, which is not conducive to carrying around.

Therefore, how to improve the working end of the wrench has become an urgent problem to be solved in this creation.

In view of this, the creator provides a wrench for the purpose of its creation. The reason is that the interchangeable structure is used to improve the working end of the wrench, and the convenience of applying various specifications is obtained.

Due to the above object, the present invention provides a wrench comprising: a grip having a grip portion and at least one bifurcated end, the bifurcated end defining two arms, the two arms enclosing a receiving space, each arm having a An operation member comprising a connecting portion, a pivot hole is formed in the center of the connecting portion; and two actuating ends are integrally formed with the connecting portion, and each actuating end forms an uneven structure along an axis, and the axes are substantially parallel and Vertically perpendicular to the length of the grip; on one axis, the shaft passes through the two holes and the pivot hole, so that the connecting portion is pivotally connected between the two arms,

The concave and convex structure of the operating member refers to a pair of polygonal holes, polygonal grooves, polygonal columns or multiple perforations and multi-tooth grooves of different specifications for combining the required workpieces, such as sleeves, posts or screws. Pieces and so on.

Therefore, when the operating member rotates about the shaft, the distance from the two operating ends to the shaft is substantially equal, and each of the actuating ends can pass through the receiving space of the grip without interfering with the rotation of the operating member. Once the shaft leaves the arm, it facilitates the interchangeable use of the operating members.

Referring to Figure 1, the specific construction of the first embodiment of the wrench 10 is illustrated. The wrench 10 has a grip 20 and two operating members 40. The grip 20 has two ends, and each end is pivotally connected to the corresponding operating member 40, so that the operating member 40 rotates relative to the grip 20.

In the second figure, the grip 20 has a grip portion 22, and the grip portions 22 are bifurcated at both ends, and are not only substantially identical in structure, but are also integrally formed with the grip portion 22. Each of the furcation ends is defined as a two-arm 24 that is enclosed by a two-arm 24 into a receiving space 26. The wall surrounding the accommodating space 26 is regarded as an inner wall 25 which is formed by a concave curved surface 21 engaging two substantially parallel planes 23 so that the accommodating space 26 conforms to the partial contour of the operating member 40 without interfering with the operating member 40. The rotation. Each arm 24 is connected to the grip 22 and a hole 28 is formed adjacent the free end of the arm 24.

Each of the operating members 40 includes a connecting portion 42 and two operating ends 46. The actuating ends 46 are integrally formed with the connecting end 42 at both ends. The width of the connecting portion 42 is smaller than the distance between the two planes 23 of the fork end of the grip 20, and a pivot hole 44 is formed in the center thereof.

In Figures 3 and 4, each of the actuating ends 46 defines a pair of hexagonal holes 48 along an axis L1, L2. These axes L1, L2 are substantially parallel and perpendicular to the longitudinal direction of the grip portion 22. Each pair of hexagonal holes 48 are connected to each other and have different specifications, such as 14 inches with 17 inches, or 16 inches for 19 inches.

A shaft 12 is passed through the two holes 28 and the pivot hole 44 to pivot the connecting portion 42. Between the two arms 24. Since the two axes L1, L2 are located on either side of the pivot hole 44, the distance from the second actuating end 46 to the shaft 12 is substantially equal. When the operating member 40 is forced to rotate about the shaft 12, the actuating end 46 does not hit the inner wall 25 of the grip 20.

In some embodiments, replacing the shaft with rivets, bolts, or other fasteners is within the scope of this creation.

Looking back at Figures 2 and 3, the wrench 10 also has a positioning mechanism 30. The positioning mechanism 30 is provided on the grip 20 to restrict the operating member 40.

The positioning mechanism 30 referred to herein refers to a combination of a steel ball 32 and a compression spring 34, and is commonly mounted in a recess 36 provided in the arm 24. The recess 36 is located in the plane 23, not only close to the shaft 12, but also has a notch smaller than the diameter of the steel ball 32. Therefore, one end of the compression spring 34 abuts against the depth of the groove 36, and the other end is abutted against the steel ball 32, and the support ball 32 is reciprocally displaced between an exposed position and a retracted position.

The exposed position means that the compression spring 34 pushes the steel ball 32 to partially expose the groove 36. At this moment, the steel ball 32 is beyond the portion of the flat surface 23, and the concave-convex fits any of the ball sockets 38 formed on the outer surface of the connecting portion 42, creating a latching or restricting action for preventing the rotation of the operating member 40, so that the operating member 40 and the grip 20 are maintained at a certain level. Angle, better positioning.

The retracted position refers to a portion of the surface of the connecting portion 42 other than the ball socket 38, forcing the steel ball 32 to move toward the depth of the groove 36, and compresses the compression spring 34 and accumulates the force required for homing.

When the grip 20 is used to perform the locking or unscrewing action, the operating member 40 and the grip portion 22 are maintained on substantially the same straight line, which not only has better grip feeling, but also does not occupy the palm. cause some damages.

Fig. 5 shows a specific configuration of the second embodiment of the wrench 10, which is substantially the same as the first embodiment, except that the operating member 40 has two pairs of multi-toothed holes 41, and each pair of multi-toothed holes 41 is formed in the corresponding The actuating end 46 replaces the original hexagonal hole.

Secondly, the wrench 10 has two positioning mechanisms 30, and each positioning mechanism 30 is composed of more than one reed 31, replacing the original steel ball and the compression spring. These reeds 31 are annular, and the recesses 33, 36 of the restricted grip 22 and the arms 24 can be placed over the shaft 12 to produce an angular positioning effect on the operating member 40.

Fig. 6 is a third embodiment of the wrench 10, the construction of which is substantially the same as that of the first embodiment, except that the outline of the operating member 40 is slightly changed, and the shape of the grip 20 is relatively adjusted.

Fig. 7 is a fourth embodiment of the wrench 10, and its configuration is substantially the same as that of the first embodiment, with the difference that "the configuration of the operating member 40 is slightly changed".

The connecting portion 42 is provided with a pair of socket portions 43 at one of the two operating ends. The socket portions 43 are square grooves that are not connected to each other, and are not only located on the same axis L1, but also have different specifications, such as 1/4. English with 5/16 inches.

The other actuating end forms a pair of short studs 45 along the axis L2. These studs 45 are square and have the same inside, and have different specifications, such as 1/4 inch with 3/8 inch. In addition, a portion of a sphere 47 is exposed on the surface of each of the studs 45 for inserting a sleeve or post of the same size.
