Description

Technical Field

[0001] This utility model relates to the field of T-wrench tools, and in particular to an adjustable T-wrench. Background Technology

[0002] T-shaped wrenches, also known as T-type wrenches, have a "T" or "T" shaped structure. They consist of a horizontal handle, a vertical socket, and a hexagonal head. They are suitable for space-constrained scenarios. The handle is usually perpendicular to the working end. Some models use an extended design or universal joint to improve flexibility. However, this fixed T-shaped structure design results in a large space occupation and inconvenient storage.

[0003] For example, Chinese utility model patent CN202878213U discloses a movable T-shaped wrench, which includes a T-shaped wrench body and a buckle at the bottom of the T-shaped wrench body. Although this solution realizes the function of assembling a T-shaped wrench with sockets of different specifications and models, the handle end is perpendicular to the working end of the socket, that is, the two ends of the handle end extend to both sides. Although this can increase the torque, it also leads to the problem that the T-shaped wrench occupies a lot of space when stored and carried. Based on this, a movable T-shaped wrench is proposed. Utility Model Content

[0004] To solve the technical problem of storing and carrying T-wrenches, this utility model provides a movable T-wrench.

[0005] This utility model is achieved using the following technical solution: a movable T-shaped wrench, comprising a limiting cylinder and a hexagonal head, wherein the limiting cylinder has an internal cavity, and a plug rod is fixedly connected to the lower side of the threaded sleeve, and a storage groove is provided inside the plug rod, the cavity and the storage groove are connected, a handle locking hole is provided through the limiting cylinder, a handle rod is provided inside the handle locking hole, the handle rod can be placed inside the storage groove after being disassembled, a wrench connecting mechanism is provided on the lower side of the limiting cylinder, and a cover mechanism is provided on the upper side of the limiting cylinder.

[0006] As a further improvement to the above solution, the wrench connecting mechanism includes a threaded rod disposed below the insert rod, the inner side of the threaded rod having a prismatic limiting groove, the insert rod being slidably connected inside the prismatic limiting groove, and the outer side of the threaded rod being provided with a threaded rod driving mechanism for reciprocating up and down along the inner side of the prismatic limiting groove.

[0007] As a further improvement to the above solution, a hexagonal prism head is fixedly connected to the lower end of the threaded rod.

[0008] As a further improvement to the above solution, the threaded rod drive mechanism includes a threaded sleeve that is threadedly engaged with the outer side of the threaded rod, and the upper side of the threaded sleeve is rotatably connected to the lower side of the limiting cylinder.

[0009] As a further improvement to the above solution, the cover mechanism includes a threaded cap that is threadedly engaged with the limiting cylinder.

[0010] As a further improvement to the above solution, the insertion rod is a prism structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. When the wrench is finished using and needs to be stored, the handle rod can be removed from the handle locking hole and placed inside the storage groove in the insert rod to complete the storage. By rotating the limiting cylinder, the threaded rod is inserted into the threaded sleeve. At this time, the wrench becomes a rod-shaped structure, which greatly reduces the space occupied and makes it very convenient to carry and store.

[0013] 2. This utility model drives the threaded rod to rotate by rotating the handle rod that has been inserted into the handle hole, causing the threaded rod to extend downward along the inside of the threaded sleeve, thereby expanding the reach of the working end of the T-wrench and improving the wrench's adaptability to different scenarios.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] Example:

[0024] Please combine Figure 1 - Figure 6 This embodiment of a movable T-shaped wrench includes a limiting cylinder 4 and a hexagonal head 3. The limiting cylinder 4 has a cavity 10 inside, which opens through the upper and lower parts of the limiting cylinder 4. A plug rod 8 is fixedly connected to the lower side of the threaded sleeve 1. In this embodiment, the plug rod 8 is a triangular prism, and a storage groove 9 is opened inside the plug rod 8. The storage groove 9 has a cylindrical spatial structure. The cavity 10 and the storage groove 9 are connected. A handle locking hole 11 is opened through the limiting cylinder 4. A handle rod 6 is provided inside the handle locking hole 11. The handle locking hole 11 and the handle rod 6 are mutually adapted. The handle rod 6 can be placed inside the storage groove 9 after being disassembled. A wrench connecting mechanism is provided on the lower side of the limiting cylinder 4, and a cover mechanism is provided on the upper side of the limiting cylinder 4.

[0025] With the above technical solution, when it is necessary to use a wrench, the handle rod 6 can be taken out from the storage slot 9 and then inserted into the handle locking hole 11. Rotating the handle rod 6 will drive the limiting cylinder 4 to rotate, and the rotation of the limiting cylinder 4 will drive the insertion rod 8 to rotate together.

[0026] Please combine Figure 1 As shown, the wrench connection mechanism includes a threaded rod 2 disposed below the insert rod 8. The length of the threaded rod 2 is less than the length of the threaded sleeve 1. A prismatic limiting groove 7 is provided on the inner side of the threaded rod 2. The insert rod 8 is slidably connected inside the prismatic limiting groove 7. A threaded rod drive mechanism is provided on the outer side of the threaded rod 2 to make the threaded rod 2 move up and down along the inner side of the prismatic limiting groove 7.

[0027] Please combine Figure 1 As shown, a hexagonal head 3 is fixedly connected to the lower end of the threaded rod 2. In this embodiment, the lower end of the threaded rod 2 is connected to the hexagonal head 3. In other embodiments, an internal hexagonal or polygonal sleeve can be connected.

[0028] Please combine Figure 2As shown, the threaded rod drive mechanism includes a threaded sleeve 1 that is threadedly connected to the outer side of the threaded rod 2. The upper side of the threaded sleeve 1 is rotatably connected to the lower side of the limiting sleeve 4. It should be noted that when it is necessary to adjust the hidden length of the threaded rod 2 inside the threaded sleeve 1, the operator should manually hold the outer side of the threaded sleeve 1 and then rotate the handle rod 6 to extend or retract the threaded rod 2 relative to the threaded sleeve 1. When the downward extension distance between the threaded rod 2 and the hexagonal head 3 is adjusted, the hexagonal head 3 can be inserted into the internal hexagonal nut that needs to be removed. At this time, the operator does not need to manually hold the threaded sleeve 1 because the insertion rod 8 and the prismatic limiting groove 7 on the inner side of the threaded rod 2 cooperate to form a torsional force.

[0029] Please combine Figure 1 As shown, the cover mechanism includes a threaded cap 5 that is threadedly connected to the limiting cylinder 4. When the threaded cap 5 is opened, the wrench position is reversed, and the handle rod 6 falls automatically under the action of gravity.

[0030] Please combine Figure 3 As shown, the insertion rod 8 has a prism structure, which helps to generate torsional force and facilitates insertion.

[0031] The implementation principle of a movable T-shaped wrench in this embodiment is as follows: When the wrench is needed, rotate the threaded cap 5 to take out the handle rod 6 inside the storage groove 9 and insert it into the handle locking hole 11 on the limiting cylinder 4. If it is necessary to adjust the downward depth of the hexagonal head 3, it can be done by tightening the outer side of the threaded sleeve 1 and then rotating the handle rod 6. At this time, the limiting cylinder 4 rotates together under the push of the handle rod 6, and at the same time, it drives the lower insertion rod 8 to rotate together. Since the outer thread of the threaded rod 2 is threaded into the inside of the threaded sleeve 1, the threaded rod 2 and the hexagonal head 3 are extended forward relative to the threaded sleeve 1. At the same time, the prismatic surface of the insertion rod 8 slides inside the prismatic limiting groove 7.

[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
