Description

Technical Field

[0001] This utility model relates to the field of hardware tools technology, specifically to a multi-functional installation tool. Background Technology

[0002] Wrenches are common installation tools frequently used in the installation and repair of faucets, angle valves, and other similar appliances. During repairs, wrenches are often used to remove the existing faucets and angle valves before installing new ones. However, in practice, faucets and angle valves often break off in the pipe joints due to rust or aging. Therefore, it's necessary to remove the broken wire first. A wire extractor can be used to remove the broken wire before the wrench is used to install the new faucet or angle valve. Existing wire extractors mainly utilize the principle of reverse threading. A tapered extractor with a reverse thread is inserted into the broken wire and rotated counterclockwise to unscrew it. During removal, a handle or other tool is needed to assist in rotating the extractor. After removal, a wrench is still required for installation. Therefore, repairing faucets requires a wire extractor, a handle, and a wrench, which can be inconvenient due to the number of tools involved. Utility Model Content

[0007] The spacing adjustment member is connected to one of the first support arm and the second support arm, and one end of the spacing adjustment member is configured to abut against the other of the first support arm and the second support arm;

[0008] The other ends of the first support arm and the second support arm are respectively provided with locking blocks. The locking blocks are configured to extend into the broken wire, and the two locking blocks are made to at least partially contact the inner surface of the broken wire by means of a spacing adjustment member.

[0009] Furthermore, the locking block is a square block, and two first locking ridges are formed between the mutually distant sides of the two locking blocks and the adjacent surfaces, and both first locking ridges are used to embed into the broken wire and press it.

[0010] Furthermore, a second locking ridge is provided on the side of the two locking blocks that are far apart from each other. The second locking ridge is used to embed into the broken wire and press it in place.

[0011] Furthermore, the two second locking edges are inclined and are configured such that when the two locking blocks contact each other on the side away from the second locking edge, the two second locking edges move closer to each other in a direction away from the hinge axis.

[0012] Furthermore, the spacing adjustment component includes an adjustment bolt, which is connected to one of the first support arm and the second support arm. One end of the adjustment bolt is configured to abut against the other of the first support arm and the second support arm, and the two locking blocks are pressed against the broken wire by rotating the adjustment bolt.

[0013] Furthermore, the adjusting bolt is provided with a wing nut, which is configured to rotate the adjusting bolt.

[0014] Furthermore, the first support arm and the second support arm are respectively provided with a first hinge seat and a second hinge seat at the ends away from the locking block, and the first hinge seat and the second hinge seat are hinged together by the hinge shaft.

[0015] Furthermore, the assistive part includes a first handle, a second handle, and an opening adjustment member. The first handle and the second handle are hinged together by the hinge shaft.

The distance between the two first clamping surfaces is smaller than the distance between the two second clamping surfaces.

[0021] The beneficial effects of this utility model are:

[0022] This utility model presents a multi-functional installation tool that integrates the functions of fixing and removing broken wires into one unit. When repairing faucets or angle valves, there is no need to prepare multiple tools such as a broken wire extractor and a handle as in traditional methods. Only this multi-functional installation tool is needed to remove the broken wire, greatly reducing the number and types of tools required, making it convenient for repair personnel to carry and use, and improving repair efficiency. By setting a spacing adjustment component, the distance between the first and second support arms can be adjusted, ensuring that at least part of the two locking blocks contact the inner surface of the broken wire. When rotating the assist part, the broken wire can be removed from the pipe joint more stably and efficiently, avoiding problems such as slippage and ineffective wire removal that may occur with traditional broken wire extractors, thus improving the success rate and efficiency of broken wire removal.

[0023] Furthermore, the assistive part includes a first handle, a second handle, and an opening adjustment component. The opening adjustment component, consisting of a handwheel and a positive / negative threaded screw, allows for convenient adjustment of the distance between the two clamping parts, thereby adjusting the jaw size. When installing a new faucet or angle valve, the jaw size can be flexibly adjusted according to different specifications of nuts or bolts, ensuring a tight fit and stable installation. This flexible adjustment method improves the tool's applicability, meeting the installation needs of various faucets and angle valves. The assistive part, through the first and second handles and the clamping parts, forms a jaw structure, allowing maintenance personnel to apply greater torque by operating the handles. Simultaneously, the opening adjustment component ensures a stable and reliable connection between the handles during jaw size adjustment. When removing broken wires or installing faucets or angle valves, the assistive part provides stable assistance, reducing the operational difficulty and labor intensity for maintenance personnel, making maintenance work easier and more efficient.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0039] like Figures 1-5 As shown, this multi-functional installation tool mainly consists of a first support arm 1, a second support arm 2, an assisting part 3, and a spacing adjustment part 4.

[0040] Figures 1-4 As shown, the first support arm 1 and the second support arm 2 serve as the main support structure of the entire tool. One end of each arm is provided with a first hinge seat 11 and a second hinge seat 21. The first hinge seat 11 and the second hinge seat 21 are hinged together by a hinge shaft 5, so that the first support arm 1 and the second support arm 2 can rotate relative to each other around the hinge shaft 5.

[0041] Locking blocks 6 are respectively installed at the other ends of the first support arm 1 and the second support arm 2. The locking blocks 6 can penetrate into the broken wire 7. At the same time, when the first support arm 1 and the second support arm 2 are far apart, the locking blocks 6 can at least partially contact the inner surface of the broken wire 7, thereby fixing the broken wire 7. Then, the assisting part 3 is rotated relative to the first support arm 1 and the second support arm 2, so that the assisting part 3 forms an angle with the first support arm 1 and the second support arm 2, thereby driving the first support arm 1 and the second support arm 2 to rotate, and the broken wire 7 can be removed.

[0042] In this embodiment, the locking block 6 is a square block, and two first locking ridges 61 are formed between the mutually distant sides of the two locking blocks 6 and the adjacent sides, respectively. The two first locking ridges 61 are used to embed into the broken wire and press against it, thereby fixing the broken wire. Alternatively, the mutually distant sides of the locking blocks 6 can also be arc-shaped, and the arc-shaped surface can be pressed against the broken wire.

[0043] Furthermore, to improve the fixing effect of the broken wire, a second locking ridge 62 is provided on the sides of the two locking blocks 6 that are far apart from each other. The second locking ridge 62 is also used to embed into the broken wire and press it, further enhancing the locking effect. Of course, the second locking ridge 62 can also be omitted. Moreover, the two second locking ridges 62 are inclined. When the sides of the two locking blocks 6 that are far away from the second locking ridges 62 come into contact, the two second locking ridges 62 move closer to each other in the direction away from the hinge shaft 5. The reason for this arrangement is that when removing the broken wire, the ends of the first support arm 1 and the second support arm 2 that are close to the locking block 6 are far apart from each other, and the distance between them at the hinge shaft 5 is limited. Therefore, the ends of the first locking ridge 61 and the second locking ridge 62 that are close to the hinge shaft 5 are difficult to make good contact with the inner surface of the broken wire. Through the above arrangement, the ends of the first locking ridge 61 and the second locking ridge 62 that are close to the hinge shaft can also maintain contact with the inner surface of the broken wire, thereby improving the fixing effect of the broken wire. Alternatively, the second locking rib 62 may not be inclined. When the two locking blocks 6 are in contact on the side away from the second locking rib 62, the two second locking ribs 62 are approximately parallel to each other.

[0044] In this embodiment, the spacing adjustment component 4 is an adjusting bolt 41, which is threadedly connected to the first support arm 1. One end of the adjusting bolt 41 can abut against the second support arm 2. In this embodiment, the adjusting bolt is an internal hex bolt, which can be screwed in with an internal hex wrench to adjust the distance between the first support arm 1 and the second support arm 2, so that the two locking blocks 6 press the broken wire and ensure that the broken wire is firmly fixed.

[0045] In some embodiments, a wing nut is provided on the adjusting bolt 41. By rotating the wing nut, the adjusting bolt 41 can be rotated, thereby adjusting the distance between the first support arm 1 and the second support arm 2, so that the two locking blocks 6 press against the broken wire, ensuring that the broken wire is firmly fixed. Of course, a wing nut may not be provided on the adjusting bolt 41. Alternatively, other types of nuts may be provided on the adjusting bolt 41, as long as they facilitate the rotation of the adjusting bolt 41.

[0046] In this embodiment, Figures 1-5 As shown, the assist unit 3 includes a first handle 31, a second handle 32, and an opening adjustment member 33. A third hinge seat 311 and a fourth hinge seat 321 are respectively provided at the ends of the first handle 31 and the second handle 32 away from the locking block 6. The third hinge seat 311 and the fourth hinge seat 321 are hinged together by a hinge pin 5, allowing the first handle 31 and the second handle 32 to rotate relative to each other around the hinge pin 5. It should be noted that... Figure 6 As shown, the assisting part 3 may also include a wrench handle, one end of which is hinged to the hinge pin 5, and the other end of which has a clamping part 34 of a fixed size for turning the bolt. The assisting part 3 is used to rotate the first support arm 1 and the second support arm 2 after the locking block 6 presses the broken end, so that the broken wire rotates. The assisting part 3 can be of other shapes, as long as it can achieve the above purpose.

[0047] The other ends of the first handle 31 and the second handle 32 are provided with clamping parts 34, forming jaws between the two clamping parts 34 for clamping components such as faucets or angle valves. The inner surfaces of the clamping parts 34 are provided with a first clamping surface 341 and a second clamping surface 342. The first clamping surface 341 is located close to the hinge shaft 5, and the second clamping surface 342 is located away from the hinge shaft 5. The distance between the two first clamping surfaces 341 is smaller than the distance between the two second clamping surfaces 342. This design can accommodate faucets or angle valves of different sizes, improving the stability and reliability of the clamping.

[0048] An elongated hole 322 is provided on the third hinge seat 311 or the fourth hinge seat 321, or both the third hinge seat 311 and the fourth hinge seat 321 are provided with elongated holes. The hinge shaft 5 is set through the elongated hole 322. The function of the elongated hole 322 is to cooperate with the opening adjustment member 33 so that when the first handle 31 and the second handle 32 can move away from each other or move closer to each other, the shape of the jaws is maintained, so that the jaws can better fit the installation part of the faucet or angle valve.

[0049] In this embodiment, the opening adjustment component 33 includes a handwheel 331 and a forward / reverse threaded screw 332. A receiving groove 35 is provided on the first handle 31 and the second handle 32 at one end near the clamping part 34. The handwheel 331 is located in the receiving groove 35. The forward / reverse threaded screw 332 passes through the first handle 31 and the second handle 32 and is connected to the handwheel 331. Simultaneously, both ends of the forward / reverse threaded screw are threaded into the first handle and the second handle, respectively. When the handwheel 331 is rotated, the forward / reverse threaded screw 332 can drive the first handle 31 and the second handle 32 to move closer or further apart, thereby adjusting the opening size of the jaws to accommodate faucets or angle valves of different sizes. The handwheel 331 is positioned at the center of the forward / reverse threaded screw 332 for easy rotation by the operator.

[0050] Working principle:

[0051] When removing the broken wire, insert the two locking blocks 6 into the broken wire. By rotating the adjusting bolt 41, the distance between the first support arm 1 and the second support arm 2 is increased, and the two locking blocks 6 move away from each other until the first locking ridge 61 and the second locking ridge 62 are embedded in the broken wire and pressed together, firmly fixing the broken wire. Then, the operator rotates the first handle 31 and the second handle 32 relative to the first support arm 1 and the second support arm 2, forming an angle with the first support arm 1 and the second support arm 2. Then, by holding the first handle 31 and the second handle 32 and applying a counterclockwise force, the first support arm 1 and the second support arm 2 rotate, thereby unscrewing the broken wire from the pipe joint.

[0052] When installing a faucet or angle valve, depending on the size of the faucet or angle valve, turn the handwheel 331 to drive the first handle 31 and the second handle 32 closer or further apart, adjusting the opening size of the jaws to clamp the faucet or angle valve in the jaws. Then, the operator holds the first handle 31 and the second handle 32 and applies clockwise force to install the faucet or angle valve into the pipe fitting.

[0053] This multi-functional installation tool integrates the functions of a broken wire remover and a wrench. When repairing faucets, operators only need to carry this tool to complete the removal of broken wires and the installation of faucets or angle valves, eliminating the need to prepare multiple tools and greatly improving the convenience of operation.

[0054] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model are within the protection scope of this utility model.
