Technical Field

[0001] This utility model relates to the field of wrench technology, specifically to a vertical wrench. Background Technology

[0002] In mechanical repair, equipment installation, and other scenarios, work in confined spaces is frequent. Existing wrenches have significant limitations when used in such spaces. For example, ordinary open-end wrenches and box wrenches are difficult to insert into narrow gaps, restricting operating space; while socket wrenches can operate at multiple angles, they are poorly adapted to extremely narrow spaces and cannot be precisely aligned in some complex spaces; elbow wrenches, although adaptable to narrow spaces to some extent, have fixed angles and limited torque transmission, making them relatively unsuitable for complex and confined layouts. Due to structural limitations, existing wrenches cannot operate flexibly in narrow gaps, resulting in low efficiency in disassembling and assembling bolts and other components, and increasing the risk of damage. Therefore, a vertical wrench is urgently needed to solve these problems. Utility Model Content

[0003] To address the technical problem that existing wrenches are difficult to operate flexibly in narrow gaps due to structural limitations, this utility model provides a vertical wrench. The vertical structure offers high flexibility, good stability, versatility, and convenience.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-4 As shown, a vertical wrench includes a wrench body 1, a first connecting piece 2, and a second connecting piece 3. The first connecting piece 2 is fixedly disposed at one end of the wrench body 1 and has a connecting hole 21. The second connecting piece 3 is fixedly disposed at the other end of the wrench body 1 and has a first notch 31 and a second notch 32, wherein the size of the first notch 31 is larger than the size of the second notch 32. The wrench body 1, the first connecting piece 2, and the second connecting piece 3 can be welded together or assembled. It should be noted that the first notch 31 and the second notch 32 are irregularly shaped. The shapes of the first notch 31 and the second notch 32 can be designed according to the type of nut or bolt to accommodate nuts and bolts of different sizes and specifications. Specifically, the shape of the first notch 31 is adapted to large nuts or bolts, and the shape of the second notch 32 is adapted to small nuts or bolts.

[0021] The process of using a vertical wrench involves using an electric drill. The drill's rotating rod engages with the connecting hole 21 of the first connecting piece 2. Depending on the need, the first notch 31 or the second notch 32 is then secured to the nut or bolt. Starting the drill rotates the first connecting piece 2, the wrench body 1, and the second connecting piece 3, thereby rotating the nut or bolt to tighten or loosen it. Alternatively, without using a drill, the wrench body 1 can be manually rotated to rotate the second connecting piece 3, which in turn rotates the nut or bolt to tighten or loosen it.

[0022] Because of its upright structure, a vertical wrench applies force along the direction of extension in a narrow space during the tightening or loosening of nuts and bolts. Therefore, a vertical wrench is perfectly suited for and can operate normally in confined spaces; it is also less prone to slippage. Vertical wrenches can not only work flexibly in extremely small, irregular, narrow gaps and tight equipment clearances, but they are also compatible with power tools such as electric drills, enabling efficient tightening operations in confined spaces. This significantly improves the efficiency and convenience of working in narrow spaces, meeting the needs for convenient tightening and loosening of bolts or nuts in mechanical repair, equipment installation, and other scenarios.

[0023] The vertical wrench of this embodiment adopts a vertical structure, which is highly flexible and has good stability, versatility and convenience. It is not easy to slip when applying force, and meets the needs of convenient tightening and loosening of bolts or nuts in narrow spaces. It not only improves operational safety, but also reduces the risk of component damage. It is suitable for various irregular narrow spaces, and also significantly improves the efficiency of bolt or nut assembly and disassembly, thereby improving equipment maintenance efficiency.

[0024] In one possible implementation, the wrench body 1 is cylindrical, and two wrench bodies 1 are provided, which are fixedly disposed between the first connecting piece 2 and the second connecting piece 3. The arrangement of two wrench bodies 1 increases the overall structural strength of the vertical wrench.

[0025] As one possible implementation, a plurality of reinforcing ribs 5 are fixedly disposed between the two wrench bodies 1, and a grip sleeve 11 is fixedly disposed on each wrench body 1. The reinforcing ribs 5 increase the overall structural strength of the vertical wrench. When a person manually rotates the wrench body 1, the grip sleeve 11 increases the friction force of gripping the wrench body 1.

[0026] In one possible implementation, two first fixing sleeves 22 are fixedly disposed on the first connecting piece 2, and two second fixing sleeves 33 are fixedly disposed on the second connecting piece 3. Each of the lever bodies 1 has a fixing post 12 at both ends, and the fixing posts 12 at both ends of each lever body 1 respectively engage with the first fixing sleeves 22 and the second fixing sleeves 33. The dimensions of the first fixing sleeves 22, the second fixing sleeves 33, and the fixing posts 12 are matched. The first connecting piece 2 is connected to the fixing posts 12 on the lever body 1 through the first fixing sleeves 22, and the second connecting piece 3 is connected to the fixing posts 12 on the lever body 1 through the second fixing sleeves 33.

[0027] Preferably, each of the first fixing sleeves 22 is provided with a first through hole, each of the second fixing sleeves 33 is provided with a second through hole, and each of the fixing posts 12 is provided with an opening. A first bolt passes through the first through hole and the opening to further lock the fixing post 12 and the first fixing sleeve 22, and a second bolt passes through the second through hole and the opening to further lock the fixing post 12 and the second fixing sleeve 33.

[0028] As one possible implementation, a third connecting piece 4 is also included. The third connecting piece 4 or the second connecting piece 3 is fixedly disposed at the other end of the wrench body 1. The third connecting piece 4 has a third notch 41 and a fourth notch 42. The size of the third notch 41 is larger than the size of the first notch 31, and the size of the fourth notch 42 is smaller than the size of the second notch 32. The third fixing sleeve 43 and the fixing post 12 are matched in size. The shapes of the third notch 41 and the fourth notch 42 are also designed according to the type of nut or bolt to accommodate bolts and nuts of different sizes and specifications. Specifically, the shape of the third notch 41 is adapted to large nuts or bolts, and the shape of the fourth notch 42 is adapted to small nuts or bolts. The third connecting piece 4 is fixedly disposed at the other end of the wrench body 1 as required. The third notch 41 and the fourth notch 42 are clamped onto the nut or bolt. When the electric drill is started, it drives the first connecting piece 2, the wrench body 1, and the third connecting piece 4 to rotate, thereby driving the nut or bolt to rotate and tighten or loosen. By setting the third connecting piece 4, the application range of the vertical wrench is increased, meeting the needs of more types of nuts or bolts.

[0029] In one possible implementation, two third fixing sleeves 43 are fixedly disposed on the third connecting piece 4, and the fixing posts 12 at both ends of each of the flaps 1 are respectively inserted into the first fixing sleeve 22 and the third fixing sleeve 43. The third connecting piece 4 is connected to the fixing posts 12 on the flap 1 through the third fixing sleeves 43.

[0030] Preferably, each of the third fixing sleeves 43 is provided with a third through hole, and the third bolt passes through the third through hole and the opening to further lock the fixing post 12 and the third fixing sleeve 43.

[0031] As one possible implementation, a sleeve 6 is also included. The sleeve 6 is fitted into the connecting hole 21 of the first connecting piece 2 and extends through the connecting hole 21. The connecting hole 21 of the first connecting piece 2 has an inner groove 23 and an inclined groove 24. A flexible sleeve 61 is fixedly mounted on the sleeve 6, and the flexible sleeve 61 passes through the inclined groove 24 and is fitted into the inner groove 23. With the flexible sleeve 61 on the sleeve 6 fitted into the inner groove 23, the sleeve 6 and the first connecting piece 2 are fixedly connected. The rotating rod of the electric drill is engaged in the sleeve 6, facilitating the connection between the electric drill and the first connecting piece 2.
