Adjustable wrench with strong device

The present invention mainly discloses an adjustable wrench, in particular, an adjustable wrench with a strong device can strengthen the structural strength of the adjustable wrench to prevent the user from improper operation or external impact and other factors causing deformation of the sidewall surfaces of the movable wrench, thereby extending the adjustable wrench. Product life.

A wrench is a hand tool that uses a lever principle to turn bolts, nuts, and other objects that are difficult to turn by hand. The wrench is usually provided with an opening at either or both ends of the handle to hold the object, and the user can rotate the object by applying an external force in the rotational direction at the other end of the handle. There are quite a few types of wrenches, one of which is a spanner wrench, and the use of the adjustable wrench is quite high, because it can freely adjust the size of the opening to accommodate multiple sizes of objects, instead of changing to different sizes of objects. The open-end wrench allows the user to replace multiple single-size open-end wrenches with a spanner wrench, which brings great convenience and applicability.

A typical adjustable wrench, as shown in U.S. Patent No. 8,136,429, "REVERSIBLE MONKEY WRENCH", which includes a handle, a head, a slidable jaw, and an axial rod.

Please refer to FIG. 1 to FIG. 4 , which are perspective views, partial exploded views and cross-sectional views of a first embodiment of a spanner having a strong device. The present invention has a spanner of a rugged device that includes a grip 10, a head 20, a movable jaw 30, an adjustment device 40 and a stiffening device 50. The handle 10 can be held by a user. The head 20 is formed at one end of the handle 10. The head 20 can also be formed at different ends of the handle 10. The head 20 includes a fixed jaw 21, a sliding slot 22, and a receiving slot 23. The two side walls 24 and the two connecting portions 25 are formed at one ends of the two side walls 24. The sliding slot 22 and the receiving slot 23 communicate with each other, and the sliding slot 22 is formed between the two side walls 24. In this embodiment, each of the connecting portions 25 is a through hole and is formed by extending from each end surface 241 of the side wall 24 away from the fixing jaw 21 toward the fixing jaw 21 . The movable jaw 30 is slidably disposed on the chute 22 of the head 20 and is movable relative to the fixed jaw 21. The adjusting device 40 is received in the receiving slot 23 of the head 20 and includes a shaft 41 and a worm wheel 42. The shaft 41 is disposed on the worm wheel 42 such that the worm wheel 42 can slide relative to the shaft 41. Rotating, the worm wheel 42 and the movable jaw 30 are mutually engaged. The reinforcing device 50 is connected between the two side walls 24 of the head 20 and is fixed to the two connecting portions 25 .

The reinforcing device 50 has a unitary structure and is slightly U-shaped. The reinforcing device 50 includes a body portion 51 and two leg portions 52 formed at different ends of the body portion 51, and each The extending direction of the leg portion 52 is substantially perpendicular to the body portion 51. The two leg portions 52 are firmly clamped to the two connecting portions 25 of the head portion 20, and the body portion 51 is in close contact with the end surface 241 of each of the side walls 24.

Thereby, when an object is clamped between the fixed jaw 21 and the movable jaw 30 and is turned, the body 51 of the reinforcing device 50 is connected between the two side walls 24 to increase the structural strength. The two side walls 24 are prevented from being deformed by the movable jaw 30, which greatly increases the service life of the adjustable wrench.

The movable raft 30 includes a swaying portion 31 and a contact portion 32. The sliding portion 31 and the contact portion 32 are slidably disposed on the sliding groove 22 of the head portion 20. The cocking portion 31 and the worm wheel 42 are mutually locked. Therefore, the worm wheel 42 can be rotated to slide the movable cymbal 30 relative to the fixed cymbal 21. The end of the contact portion 32 away from the fixed cymbal 21 has a contact surface 321 which is concavely curved and selectively Contact with the body 51 of the reinforcing device 50, so that when the worm wheel 42 is rotated to slide the movable jaw 30 relative to the fixed jaw 21 to adjust the size of the opening formed between the fixed jaw 21 and the movable jaw 30, the maximum size can be obtained. The size of the opening allows the adjustable wrench to increase the size range of the object to be turned.

The head 20 further includes a shaft hole 26 communicating with the pocket 23, one end of the shaft 41 is disposed through the worm wheel 42, and the other end of the shaft 41 is fixedly connected by screwing. The shaft hole 26. The adjusting device 40 further includes an elastic member 43 that is sleeved on the shaft 41 and elastically supported between an inner wall surface 231 of the receiving groove 23 and the worm wheel 42.

Please refer to FIG. 5 to FIG. 6 , which are perspective views and partial exploded views of a second embodiment of a spanner having a strong device. The second embodiment of the present invention is substantially the same as the first embodiment, and the same structure in the second embodiment follows the reference numerals of the first embodiment, and details are not described herein again. The difference in the embodiment is that the reinforcing device 50a includes a connecting member 51a, two connecting holes 52a and two fasteners 53a formed on the connecting member 51a and corresponding to the two connecting portions of the head 20. The two fasteners 53a are respectively disposed in the two connecting holes 52a and connected to the two connecting portions 25. The connecting member 51a is in close contact with the end surface 241 of each of the side walls 24, and the contact surface 321 is concavely curved and selectively contacts the connecting member 51a.

Thereby, when an object is clamped between the fixed jaw 21 and the movable jaw 30 and is turned, the connecting member 51a of the reinforcing device 50a is connected between the two side walls 24 to increase the structural strength. The two side walls 24 are prevented from being deformed by the movable jaw 30, which greatly increases the service life of the adjustable wrench.

Please refer to FIG. 7 to FIG. 8 , which are perspective views and partial exploded views of a third embodiment of an adjustable wrench with a strong device. The third embodiment of the present invention is substantially the same as the first embodiment, and the same structure in the third embodiment follows the reference numerals of the first embodiment, and details are not described herein again. The difference between the embodiments is that each connecting portion 25a of the head portion 20 is a recessed groove and is formed by one side surface 242 of each of the side walls 24 extending toward the fixing jaw 21, and the extending direction of the side surface 242 and the end surface 241 The direction of extension is slightly vertical. The two leg portions 52 of the reinforcing device 50 are firmly clamped to the two connecting portions 25a of the head portion 20.

In summary, the active wrench with the strong device has the following advantages:

1. When an object is clamped between the fixed jaw 21 and the movable jaw 30 and is turned, the body 51 of the reinforcing device 50 is connected between the two side walls 24 to increase structural strength and avoid The two side walls 24 are disassembled by the movable jaw 30 to be deformed, which greatly increases the service life of the adjustable wrench.

The movable raft 30 includes a swaying portion 31 and a contact portion 32. The sliding portion 31 and the contact portion 32 are slidably disposed on the sliding groove 22 of the head portion 20, and the swaying portion 31 and the worm wheel 42 are mutually When the worm wheel 42 is rotated, the movable cymbal 42 can be driven to slide relative to the fixed cymbal 21. The end of the contact portion 32 away from the fixed cymbal 21 has a contact surface 321 which is concavely curved and selected. Contacting the body 51 of the reinforcing device 50 so that when the worm wheel 42 is rotated to slide the movable jaw 30 relative to the fixed jaw 21 to adjust the size of the opening formed between the fixed jaw 21 and the movable jaw 30, Get the largest opening size and increase the range of the adjustable size of the adjustable wrench.

In summary, this creation is not seen in the previously disclosed technology, so it has the novelty and advancement of patents, and the value of the use of the industry; the applicant filed a new patent application with the bureau in accordance with the provisions of the Patent Law.
