Description

adjustable wrench

This creation is related to a wrench, especially a wrench that can be used to continuously twist or loosen a hex nut.

Press, the general adjustable wrench uses a movable cymbal and a fixed cymbal to clamp the nut (or bolt) from one side to tighten or retract the nut.

However, when the obstacle is blocked by a certain obstacle in the process, the movable wrench must be disengaged from the side of the nut, and then the movable wrench is moved to a position suitable for turning, and then can be turned again, which is quite troublesome.

In order to solve the above problems, there is a wrench as shown in FIG. 7 , which is mainly composed of a first cymbal 91 , a second cymbal 92 , and a grip 93 . The first cymbal 91 is provided with a chute . 911, the second jaw 92 is movable along the sliding slot 911, and is biased against the first jaw 91 by a spring; the first jaw 91 and the second jaw 92 respectively have a clamping portion 94, and a second clamping portion 94 is formed between the two clamping portions 94. The clamping portion of the nut is clamped; the second jaw 92 has a recess 95, and the grip 93 has a restricting block 96, and the restricting block 96 and the recess 95 abut each other, whereby the user only needs to put the wrench The nut is clamped by the clamping mouth, and then the grip 93 is repeatedly turned over, so that the nut can be driven in one direction to achieve the purpose of continuously twisting or unscrewing the nut.

However, since the two clamp portions 94 of the wrench are parallel to each other, when the handle 93 is swung, the nut is easily separated from the jaw, resulting in inconvenience in use.

Moreover, although the wrench can make the first jaw 91 and the second jaw 92 away from each other, the jaw is enlarged to clamp the nut, but the direction in which the first jaw 91 and the second jaw 92 are away from each other is perpendicular to the grip 93. When the nut is located in a small space, the movement of the first jaw 91 and the second jaw 92 is restricted, and it is difficult to smoothly enlarge the jaw to clamp the nut.

In view of this, how to solve the above problems is the primary issue that the creative office wants to solve.

Please refer to FIG. 1 to FIG. 6 for the preferred embodiment selected for the present invention. This is for illustrative purposes only and is not limited by the embodiments.

As shown in Figures 1 to 3, an active wrench is provided for the creation, which is mainly composed of a first 颚 1, a second 颚 2 and a handle 3, wherein:

The first cymbal 1 has a curved shape and has a first hook portion 11 and a recess 12 is formed on each of the two sides of the first cymbal 1 .

The second cymbal 2 has a U-shaped recess 21, and a pair of latches 22 are formed on the inner side walls of the recess 21, and the second cymbal 2 is disposed corresponding to the chute 22 12, the second jaw 2 can slide its block 22 along the chute 12. A second hook portion 23 spaced apart from the first hook portion 11 is formed on a side of the second hook 2 away from the recess 21, and the second hook portion 23 faces the first hook portion 11 The curved portion is formed to form a C-shaped space between the first jaw 1 and the second jaw 2, and the jaw 13 is engageable by a nut. The second cymbal 2 is provided with at least one U-shaped notch 24 on one side of the recess 21, and the inner edge of the notch 24 has a first sidewall 241 and a second opposite to the first sidewall 241 Side wall 242, and in this embodiment, two notches 24.

The handle 3 has a connecting portion 31 pivotally connected to the first cymbal 1 , and the connecting portion 31 is formed with at least one pair of bumps 32 which should be notched 24 , in this embodiment, two bumps 32 , The bump 32 abuts against the inner edge of the notch 24. The connecting portion 31 is formed by two plates 33 spaced apart from each other, and a cavity 34 is formed between the two plates 33. The receiving chamber 34 has a blocking block 35 therein, and the first 颚1 is integrated. An operation portion 14 extending in the direction of the chamber 34 is formed, and a portion of the operation portion 14 is exposed outside the chamber 34, and an elastic member 15 is disposed between the stopper block 35 and the operation portion 14. The embodiment is a compression spring. The two ends of the elastic member 15 respectively resist the blocking block 35 and the operating portion 14 , and when the operating portion 14 is pressed, the operating portion 14 drives the first 枢 1 pivoting And the second cymbal 2 is abutted against the notch 24 and the protrusion 32, so that the second cymbal 2 linearly slides along the sliding slot 12 and is relatively far away from the first cymbal 1 to further The first hook portion 11 is gradually separated from the second hook portion 23, and the nut can be inserted into the jaw 13. When the urging force is stopped, the elastic member 15 is moved by the returning elastic force to pivot the first cymbal 1 and simultaneously drive the second cymbal 2 along the sliding slot 12 toward the first cymbal 1 The direction is moved to further reduce the distance between the first hook portion 11 and the second hook portion 23, so that the nut located in the jaw 13 when the handle 3 is pivoted is not easily separated from the jaw 13.

Of course, since the first jaw 1 can be pivoted, the first hook portion 11 and the second hook portion 23 can directly push the nut, and the nut is squeezed by the pivoting of the first jaw 1 The first jaw 1 slides into the jaws 13.

In the embodiment, the jaws 13 are substantially circular, and the first jaws 1 and the second jaws 2 are respectively formed with a plurality of molars 19 on one side thereof facing the jaws 13 , and the jaws are 19 is disposed at an equidistant interval between the center of the jaws 13 and at least less than or equal to a predetermined angle θ, and the predetermined angle θ is thirty degrees, so that the jaws 13 can pass through the respective jaws When the teeth 19 and the outer edge of the nut (for example, a hexagonal nut) cooperate to hold the first jaw 1 and the second jaw 2, the nut can be more stably clamped.

Further, the extending direction of the sliding slot 12 defines a first extension line D, and the extending direction of the handle 3 has a second extension line C, and the first extension line D and the second extension line C are mutually They are arranged obliquely without being perpendicular to each other, whereby when the nut is embedded, the expansion space required to force the first jaw 1 to pivot outward and the second jaw 2 to move along the slot 12 can be reduced.

As shown in FIG. 4, when the bump 32 abuts against the first side wall 241 of the notch 24 (that is, when the handle 3 moves in the clockwise direction in the figure), the second 颚2 will Moving along the chute 12 in the direction of the first weir 1 so that the second weir 2 and the first weir 1 are in a clamping position A, and the inner diameter of the jaw 13 is reduced and the jaw is maintained. 13 size.

As shown in FIG. 5, when the bump 32 abuts against the second side wall 242 of the notch 24 (that is, when the handle 3 is pivoted in the counterclockwise direction in the figure), the second 颚 2 Moving along the chute 12 away from the first cymbal 1 so that the second cymbal 2 and the first cymbal 1 are in a slip position B, and when the second 颚 2 and the first 颚 1 When the sliding position B is located, the inner diameter of the jaw 13 is greater than the outer diameter of the nut, and is smaller than the jaw 13 of the second jaw 2 and the first jaw 1 at the clamping position A. the inside diameter of.

When the original composition of the above structure is used in actual use, the user first applies an external force to the operating portion 14 to cause the operating portion 14 to compress the elastic member 15 and drive the first 枢1 pivoting The second jaw 2 and the first jaw 1 are relatively far apart from each other and deployed, allowing the jaws 13 to have a sufficient distance to embed a nut to be twisted or unscrewed. When the user stops applying an external force to the operating portion 14, the elastic member 15 pushes the operating portion 14 to move due to its returning elastic force, and simultaneously drives the first 颚1 pivoting to make the first 颚1 A hook portion 11 and a second hook portion 23 of the second jaw 2 are adjacent to each other, and the nut is firmly clamped in the jaw 13. Then, the user pivots the handle 3 toward the side with the nut as the axis, and the protrusion 32 abuts against the first side wall 241 of the notch 24, so that the second cymbal 2 slides along the shank 2 The groove 12 is moved in the direction of the first weir 1 so that the second weir 2 and the first weir 1 are located at the clamping position A, and the nut is clamped through the second weir 2 and the first weir 1 In the jaw 13 , the nut is pivoted with the handle 3 synchronously, and the nut can be twisted or unscrewed.

After the handle 3 is pivoted by a predetermined distance, the user only needs to pivot the handle 3 toward the other side thereof, so that the protrusion 32 abuts against the second side wall 242 of the notch 24, and the second The 颚2 moves along the chute 12 away from the first cymbal 1 such that the second cymbal 2 and the first cymbal 1 are located at the slip position B, and the second 颚2 and the first 颚1 are caused by The jaw 13 is enlarged to no longer clamp the nut, and then the foregoing operation is repeated, the second jaw 2 and the first jaw 1 are moved to the clamping position A, and the pivoting is performed again. Achieve continuous twisting or loosening the nut.

As can be seen from the foregoing description, the present invention has an advantage in that it can resist the operating portion 14 through the elastic member 15, thereby the first hook portion 11 abutting the second hook portion 23 and engaging the first hook portion 11 The second hook portion 23 has a curved arc shape, and the nut located in the jaw 13 is firmly clamped, thereby effectively preventing the nut located in the jaw 13 from slipping out of the jaw when operating. 13 situation.

In addition, as shown in FIG. 6, the creation is further slidable by the pivot of the first cymbal 1 and the second cymbal 2, and when moving away from each other, the moving direction and the extending direction of the handle 3 The design is moved in a relatively oblique direction, thereby effectively reducing the expansion space required for the first jaw 1 and the second jaw 2 to move away from each other to allow the nut to be inserted into the jaw 13.

However, the above description of the embodiments is merely illustrative of the present invention and is not intended to limit the present invention. Therefore, the replacement of equivalent elements should still be within the scope of the present invention.

In summary, when it is clear that the person skilled in the art understands that the creation can achieve the aforementioned objectives, it has already complied with the provisions of the Patent Law, and therefore applied according to law.
