[0047] Example 3

[0048] Reference Figures 5-6 , which is the third embodiment of the present invention, and is different from the above two embodiments. This embodiment provides a string handle wrench,

[0049] It comprises a handle 100, a connecting piece 200 is arranged at one end of the handle 100, and a detachably connected first bolt sleeve 300 is arranged at one end of the connecting piece 200;

[0050] The second bolt sleeve 400 is sleeved on the outside of the handle 100 . At least one second bolt sleeve 400 is provided, and the second bolt sleeve 400 and the first bolt sleeve 300 can be interchangeably installed.

[0051] It should be noted that the provision of the connecting member 200 facilitates the installation and replacement of the first bolt sleeve 300 and the second bolt sleeve 400. The second bolt sleeve 400 can replace the first bolt sleeve 300. When multiple second bolt sleeves 400 are provided, different models of second bolt sleeves 400 can be replaced according to actual usage conditions, thereby reducing the tools carried by the user and the time spent searching for and replacing tools at high altitudes, greatly reducing the user's high-altitude working time and detention time, and reducing safety hazards.

[0052] Preferably, bolt sleeves of different models and specifications can be quickly replaced, which can reduce the tools carried during high-altitude operations, reduce the time for finding sleeves of suitable specifications and replacement, reduce the time spent in high-altitude operations, reduce safety hazards, and at the same time, the overall production is simple and convenient for mass production.

[0053] Furthermore, the first bolt sleeve 300 and the second bolt sleeve 300 are both provided with a through hole A, a limiting hole is provided at one end of the through hole A, the connecting member 200 is detachably connected to the first bolt sleeve 300 or the second bolt sleeve 400 through the through hole A, and the first bolt sleeve 300 or the second bolt sleeve 400 is sleeved on the outside of the handle 100 through the through hole A.

[0054] It should be noted that the apertures of the through holes A provided in the first bolt sleeve 300 and the second bolt sleeve 300 are the same. The second bolt sleeve 300 is sleeved on the outside of the handle 100 through the through hole A, so as to facilitate the replacement of the second bolt sleeve 300. Meanwhile, the first bolt sleeve 300 can also be sleeved on the outside of the handle 100 through the through hole A.

[0055] Preferably, by providing a through hole A on the first bolt sleeve 300 and the second bolt sleeve 400 and providing a limiting hole at one end, the connecting piece 200 can be detachably connected to the first bolt sleeve 300 and the second bolt sleeve 300 through the through hole A. This design provides a high degree of flexibility and disassembly. This design allows the bolt sleeve to fit tightly against the outside of the handle 100, reducing the additional space occupied, making the overall structure more compact and convenient for carrying and storage. Since the first bolt sleeve 300 and the second bolt sleeve 400 both adopt the same through hole A design, this universal design allows the connecting piece 200 to be easily connected to any bolt sleeve, thereby improving the interchangeability of accessories and the convenience of use. This design allows the handle 100 to be used with different first bolt sleeves 300 or second bolt sleeves 300, thereby improving the adaptability of the handle and being able to adapt to a variety of different usage scenarios and needs.

[0056] Further, when the second bolt sleeve 400 is provided as one, the sizes of the limiting holes of the second bolt sleeve 400 and the first bolt sleeve 300 are inconsistent;

[0057] When at least two second bolt sleeves 400 are provided, the sizes of the limiting holes of the plurality of second bolt sleeves 400 and the first bolt sleeve 300 are inconsistent.

[0058] It should be noted that magnets are installed at both ends of the first bolt sleeve 300 and the second bolt sleeve 400, with the magnet S at one end exposed to the outside and the N pole of the magnet at the other end exposed to the outside. According to the principle that like poles repel each other and opposite poles attract each other, multiple second bolt sleeves 400 can be connected and fixed, and the first bolt sleeve 300 and the second bolt sleeve 400 can also be connected and fixed.

[0059] Preferably, when multiple second bolt sleeves 400 are provided, a suitable second bolt sleeve 400 can be selected according to the actual situation on site, which can also speed up work efficiency. At the same time, the second bolt sleeve 400 can be replaced with the first bolt sleeve 300. When the first bolt sleeve 300 cannot be used, quickly replacing the qualified second bolt sleeve 400 can quickly solve the working condition, and at the same time can reduce the carrying of tools and the situation of searching for tools. By setting different sizes of limit holes in the second bolt sleeve 400, the second bolt sleeve 400 can adapt to bolts of different specifications and types, so that it can adapt to various complex connection requirements.
