Description

wrench

The present invention is related to wrenches.

Wrench is one of the commonly used hand tools in the manufacturing industry. It is often used to turn fasteners such as bolts and nuts. It corresponds to various types of fasteners or usage requirements. There are various types of wrenches, such as but not limited to openings. Wrench, ring wrench, adjustable wrench, ratchet wrench... etc., or the wrench disclosed in Taiwan patents M605149, I716192, M588608 belongs to this category.

However, with this type of wrench, the rod cannot swing relative to the wrench, so a wider space is needed to allow the rod to fully rotate and be used, and the position of the rod is often limited by the surrounding environment, making it impossible to avoid obstacles smoothly Things apply force. Therefore, it is necessary to provide a novel and progressive wrench to solve the above problems.

The main purpose of the present invention is to provide a wrench, the rod can be adjusted to the appropriate force application position relative to the wrench for driving, and the insertion hole structure allows the user to replace various adapters to correspond to different styles of tightness. firmware.

To achieve the above object, the present invention provides a wrench, comprising: a rod and a wrench. The triggering member is swingably connected to the rod member, and the triggering member is provided with an inserting hole through which an adapter piece can be inserted replaceably.

The following examples illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention.

Please refer to FIG. 1 to FIG. 6 , which show an embodiment of the present invention. The wrench of the present invention includes: a rod 1 and a wrench 2 .

The trigger member 2 is swingably connected to the rod member 1 to form a joint-like movable structure with multiple use angles to be suitable for different use environments, for example, it is used to remove the clutch nut in the engine room of an automobile. Moreover, the triggering member 2 extends in a plate shape to increase the touchable length and swing range. What is important is that the puller 2 is provided with an insertion hole 21, and the insertion hole 21 is for an adapter 5 to be plugged in replaceably to correspond to different styles of fasteners, wherein the adapter 5 is for example But not limited to sockets, tool adapters...etc.

It is worth mentioning that the inserting method of the trigger 2 through the inserting hole 21 to connect the adapter 5 can effectively reduce the stacking of the thickness, thereby making it easier to move in a narrow space, and the inserting The structure of the hole 21 is relatively simple and fast in manufacture, so the production cost can be effectively saved and the production efficiency can be improved.

The insertion hole 21 is preferably a regular polygonal hole, and can have a symmetrical structure to generate a uniform force between the adapter piece 5 . In this embodiment, the insertion hole 21 is a regular hexagonal hole, which can fit most commercially available sleeves. Furthermore, a socket 22 is recessed on the peripheral wall 211 surrounding the insertion hole 21, a part of a limiting member 3 is embedded in the socket 22, and another part of the limiting member 3 It protrudes from the slot 22 for the clamp to limit the adapter piece 5 , so that the limit piece 3 can firmly position the adapter piece 5 during use and is not easy to loosen and fall off.

Preferably, the brightness of the triggering member 2 is higher than that of the rod member 1 , and when the triggering member 2 penetrates into a narrow space, the high brightness can help the user to see and know the position.

A first end 11 and a second end 14 opposite to each other are defined in the axial direction of the bar member 1, the first end 11 is connected to the trigger member 2, and the second end 14 is provided with a set of driving tools combined The joint 15 is used to reduce the labor load. In this embodiment, the set of joints 15 is a pneumatic head and can be assembled with a driving tool to more easily drive the rod 1 to drive the wrench 2 to rotate the fastener.

More specifically, the first end 11 of the rod member 1 is provided with two ear portions 12, one end of the triggering member 2 is inserted between the two ear portions 12, and a pin member 4 is passed through to connect the triggering member. 2 and the two ear portions 12, and furthermore, the pulling member 2 can swing on the pin 4 as an axis. More specifically, the first end 11 is further provided with a bottom 16, and the bottom 16 is transversely connected between the two ear portions 12, and the triggering member 2 remains against the bottom 16 during the swinging process, so During actual operation, the bottom 16 can continuously provide support force to the triggering member 2 , and the triggering member 2 can stably maintain a predetermined position relative to the rod 1 .

In this embodiment, the triggering member 2 further includes a pivot hole 23, and the pin 4 passes through the first end 11 of the rod 1 and is connected to the pivot hole 23. The diameter of the pivot hole 23 is Smaller than the diameter of the insertion hole 21, the pin member 4 is passed through and connected to the pivot hole 23, and the center of the pivot hole 23 and the center of the insertion hole 21 are both located on a central axis 24 of the plate moving member , the wrenching member 2 is arranged symmetrically with respect to the central axis 24 .

The pulling member 2 defines a driving side 25 and a connecting side 26 opposite to each other along the central axis 24, the connecting side 26 is provided with the pivot hole 23, and the driving side 25 is provided with the insertion hole 21; , define a thickness direction 27 as perpendicular to the central axis 24, in the thickness direction 27, the thickness of the driving side 25 is greater than the thickness of the connecting side 26, and the driving side 25 and the connecting side 26 form a stepped shape. The thickness of the driving side 25 is thicker and can have better structural strength to withstand the reaction force from the adapter 5 when the fastener is rotated; while the thinner connecting side 26 can be inserted into the two ears Between parts 12 to ensure that the overall thickness is within an appropriate range.

Preferably, the side of the first end 11 away from the second end 14 is provided with an arc-shaped surface 13, and when the rod 1 is extended in the process of an unexpected collision, the structure of the arc-shaped surface 13 can Reduce stress concentration damage to maintain the integrity of the structure, and avoid the situation that it cannot be moved by jamming with other components; wherein, when the trigger 2 swings and is perpendicular to the rod 1, the axis of the rod 1 In the direction, the part of the arc-shaped surface 13 is preferably protruding from the pulling member 2 .
