A prominent problem is that the same wrench cannot be used simultaneously for different sizes of internal or external hex bolts or nuts. Due to the complex environment of high-altitude work, carrying a large number of tools is both inconvenient and unsafe. Frequent wrench changes not only reduce efficiency but also increase operational risks. For example, internal hex wrenches can usually only be matched with bolts of a specific size, while external hex wrenches are also limited by their opening size. Faced with fasteners of various sizes, workers have to carry multiple wrenches, which not only increases the load but may also lead to chaotic tool management and even safety accidents such as tools falling.

[0003] Therefore, it is necessary to provide a titanium-steel composite multi-functional wrench to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0025] The following is in conjunction with the appendix Figure 1 Further description of this utility model: A titanium-steel composite multifunctional wrench includes a socket 1 and a handle 2. One end of the handle 2 is hinged to one end of the socket 1, and the other end of the socket 1 is detachably connected to a socket head 4. The socket 1 has a receiving cavity 11 for accommodating the handle 2. A pin 5 is movably disposed on the socket 1, and the handle 2 has multiple pin holes 21 adapted to the pin 5. The movable end of the handle 2 is detachably connected to the jaws 6. In this utility model, the handle 2 rotates around the hinge axis 9 on the socket 1, and then the position between the handle 2 and the socket 1 is fixed by the pin 5. The pin 5 is inserted into different pin holes 21 on the handle 2, which can change the included angle between the handle 2 and the socket 1. When the included angle between the handle 2 and the socket 1 is 0°, the handle 2 is accommodated in the socket 1. Refer to the attached drawing. Figure 2 When the angle between the handle 2 and the socket 1 is 90°, the handle 2 and the socket 1 are perpendicular, and the handle 2 rotates the hex bolt via the socket head 4. (See attached diagram.) Figure 3 When the angle between the wrench handle 2 and the socket 1 is obtuse, the worker can hold the socket 1 to tighten the bolt or nut, which is equivalent to extending the length of the wrench handle 2. This structural design facilitates the rotation of hexagonal bolts or nuts through the jaws 6. Secondly, the detachable design of the socket head 4 and the socket 1 allows for easy replacement of the appropriate socket head 4 according to the bolt size; similarly, the detachable design of the jaws 6 and the wrench handle 2 allows for easy replacement of the appropriate jaws 6 according to the bolt size. When working at heights, it is not necessary to carry various types of wrenches to tighten different sizes of internal or external hexagonal nuts or bolts, reducing the workload.

[0026] One embodiment of the movable setting of the pin 5: after passing through the sleeve 1 and the handle 2, the pin 5 is engaged with the locking pin 7. Specifically, the locking pin 7 is inserted into the hole of the pin 5 to lock the pin 5 on the sleeve 1 and the handle 2. This structural design makes it convenient to remove the pin 5 and insert it into different pin holes 21 on the handle 2.

[0027] One embodiment in which the handle 2 and the jaws 6 are detachably connected: see attached... Figure 4 The movable end of the wrench handle 2 is provided with a first insert block 22 that mates with the first insertion hole of the jaws 6. The first insert block 22 is provided with a first spring positioning pin 8. The wall of the first insertion hole is provided with a locking hole 61 that mates with the first spring positioning pin 8. The first insert block 22 is inserted into the first insertion hole, and the pin end of the first spring positioning pin 8 is inserted into the locking hole 61 to complete the installation of the wrench handle 2 and the jaws 6. This structural design allows for quick replacement of the jaws 6. Specifically, the first insert block 22 is provided with one first spring positioning pin 8, and two locking holes 61 are respectively provided on the opposite walls of the first insertion hole.

[0028] As another embodiment of this utility model: the handle 2 is provided with a scale. With this structural design, the handle 2 can be used as a ruler. When it is necessary to measure the size of nuts or bolts, the need to carry additional measuring tools is eliminated.

[0029] As another embodiment of this utility model: the handle 2 is provided with multiple weight-reducing holes 23. This structural design is beneficial to reduce the weight of the titanium steel composite multi-functional wrench.

[0030] In another embodiment of this utility model, the weight-reducing holes 23 are in two sets, arranged side by side, with the weight-reducing holes 23 in each set distributed along the length of the handle 2. This multi-hole design helps maintain the structural strength of the handle 2 as much as possible while reducing weight.

[0031] One embodiment of the hinged connection between the handle 2 and the sleeve 1: This embodiment also includes a hinge shaft 9, which passes through the sleeve 1 and the handle 2 and is threadedly connected to the fastening nut.

[0032] As another embodiment of this utility model: the hinge shaft 9 is provided with a plum blossom handle 100, which facilitates the rotation of the hinge shaft 9.

[0033] One embodiment in which the sleeve 4 and the sleeve 1 are detachably connected: Refer to the attached document. Figure 5 and attached Figure 6 The sleeve 4 includes a connecting cylinder 41, with a second insertion hole 411 inside. The sleeve 1 has a second insertion block 12 that mates with the second insertion hole 411. A second spring positioning pin is provided between the connecting cylinder 41 and the second insertion block 12. The connecting cylinder 41 has a locking hole 61 that engages with the second spring positioning pin. The second insertion block 12 is inserted into the second insertion hole 411, and the pin end of the second spring positioning pin is inserted into the locking hole 61 to complete the installation of the sleeve 4 and the sleeve 1. This structural design allows for quick replacement of the sleeve 4.

[0034] As another embodiment of this utility model: a second spring positioning pin is installed on the second insertion block 12, the second insertion hole 411 is a square hole, and the four hole walls of the second insertion hole 411 are provided with locking holes 61 that cooperate with the second spring positioning pin.

[0035] Specifically, the cross-section of the first insert 22 is rectangular.

[0036] In another embodiment of this utility model: a test pen 3 is provided at the end of the sleeve 1 away from the socket head 4, and one end of the handle 2 is hinged inside the sleeve 1 between the test pen 3 and the socket head 4. Both the sleeve 1 and the handle 2 are made of titanium alloy. The test pen 3 is located at the end of the titanium alloy sleeve 1, making full use of the insulating properties of titanium alloy, so that holding the titanium alloy sleeve 1 for measurement will not pose a life-threatening risk to the workers. Secondly, it takes advantage of the lightweight and high-strength properties of titanium, which can reduce the overall weight while allowing for greater design space, thus achieving durability and multi-functionality. Thirdly, the corrosion-resistant properties of titanium alloy allow this wrench to be used in extreme environments with high corrosiveness, such as underwater, and it can be used normally simply by replacing the steel wrench end. Preferably, a digital display 13 for displaying the test pen measurement results is provided on the sleeve 1 near the test pen 3, so that the specific measurement results can be displayed intuitively.

[0037] Specifically, both jaw 6 and socket 4 are made of steel, which takes advantage of the low cost and wear resistance of steel. This ensures the stability and replaceability of the wrench end that has the highest contact frequency with bolts or nuts. Users only need to replace the worn or damaged wrench end, instead of replacing the entire wrench, thus reducing maintenance costs.

[0038] In this invention, the wrench handle 2 rotates around the socket 1 and is then fixed by the pin 5. The wrench handle 2 and the socket 1 work together to make tightening the screws easier. Furthermore, the detachable design of the jaws 6 and the wrench handle 2, as well as the detachable design of the socket head 4 and the socket 1, allows the titanium steel composite multi-functional wrench to adapt to nuts and bolts of various sizes, improving the wrench's versatility and flexibility; it also facilitates wrench maintenance.
