[0025] See also Figure 1A portable maintenance wrench includes a wrench handle 1, an adjusting block 2, a locking assembly 4, and a wrench head 5. The wrench handle 1 can be made of ordinary carbon steel. To reduce weight, it can also be made of carbon fiber. The adjusting block 2 is hinged to the end of the wrench handle 1 through a connecting shaft 3, so that the adjusting block 2 can rotate around the connecting shaft 3, thereby changing the angle between the wrench handle 1 and the adjusting block 2, making it convenient for maintenance workers to work in narrow spaces; one end of the adjusting block 2 is hingedly connected to the wrench handle 1, and the other end is fixedly connected to a detachable wrench head 5. The angle of the wrench head 5 can be changed by rotating the adjusting block 2; see Figure 2 Sockets 21 are evenly arranged at the hinged positions on the adjustment block 2. The sockets 21 are evenly distributed along the circumference of the connecting shaft 3, and the number of sockets 21 can be increased or decreased according to actual usage requirements. A locking assembly 4 corresponding to the sockets 21 is installed on the wrench handle 1. The locking assembly 4 can fix the position of the adjustment block 2 to ensure the stability of the wrench during use. Furthermore, wrench heads 5 corresponding to bolts or nuts of different specifications can be processed according to needs. When performing maintenance, maintenance personnel only need to carry one wrench handle 1 and multiple wrench heads 5 of different specifications, which greatly reduces the carrying weight and thus reduces the labor intensity of maintenance personnel. The wrench heads 5 can be quickly replaced to ensure maintenance efficiency.

[0026] See also Figure 2 、 3 The locking assembly 4 includes a slide bar 41, a slider 42, and a locking rod 44. A slide groove 11 is provided on the lever handle 1. The slide bar 41 is slidably connected in the slide groove 11, and a slider 42 is provided on the side of the slide bar 41. The slider 42 is slidably connected to the lever handle 1. When in use, the slide bar 41 can be driven to slide by toggling the slider 42; a first locking hole 12 is provided on the lever handle 1, and a second locking hole 43 is provided on the slider 42. When the first locking hole 12 and the second locking hole 43 are aligned, the locking rod 44 is inserted to fix the position of the slider 42. At this time, the slide bar 41 is inserted into the socket 21 to lock the adjusting block 2, thereby fixing the position of the wrench head 5. If the angle of the wrench head 5 needs to be changed, pull out the locking rod 44, slide the slider 42 in the direction away from the adjusting block 2, and drive the slide rod 41 to disengage from the socket 21. At this time, adjust the angle of the adjusting block 2 according to the use requirements so that the socket 21 corresponding to this angle is aligned with the slide rod 41, and move the slider 42 to drive the slide rod 41 to insert into the socket 21, so that the position of the wrench head 5 can be fixed again.

[0027] See also Figure 4Two force-bearing rods 51 are symmetrically provided at the end of the wrench head 5. A force-bearing groove 23 corresponding to the force-bearing rod 51 is provided on the adjustment block 2. The force-bearing rod 51 is plugged into the force-bearing groove 23. The force-bearing rod 51 ensures the stability of the wrench head 5 during use. Furthermore, in order to facilitate the fixation of the wrench head 5, a connecting rod 52 is provided at the end of the wrench head 5. A connecting groove 24 corresponding to the connecting rod 52 is provided on the adjustment block 2. The connecting rod 52 is plugged into the connecting groove 24. A first fixing hole 22 is provided on the adjustment block 2. A second fixing hole 53 corresponding to the first fixing hole 22 is provided on the connecting rod 52. When the wrench head 5 is fitted with the adjustment block 2, the first fixing hole 22 and the second fixing hole 53 are aligned. At this time, they are connected by plugging through the fixing rod 6 to fix the position of the wrench head 5.

[0028] On the basis of the above embodiment, in order to ensure the stability of the locking rod 44 after being inserted into the first locking hole 12, see Figure 2 , an internal thread is provided at the second locking hole 43, and an external thread is provided at the area where the locking rod 44 contacts the second locking hole 43. When in use, the threaded connection ensures that the locking rod 44 cannot easily slide out of the second locking hole 43. Similarly, see Figure 4 An internal thread is provided at the first fixing hole 22, and an external thread is provided in the area where the fixing rod 6 contacts the first fixing hole 22. When in use, the first fixing hole 22 and the fixing rod 6 are connected by threads to prevent the fixing rod 6 from slipping out of the first fixing hole 22.

[0029] Specific working process:

[0030] Select a matching wrench head 5 according to the bolt or nut, install the wrench head 5 on the adjusting block 2, and fix it with the fixing rod 6; if it is necessary to adjust the angle of the wrench head 5, remove the locking rod 44, slide the slider 42 to disengage the slider 41 from the socket 21, rotate the wrench head 5 to adjust, and after the adjustment is completed, slide the slider 42 to insert the slider 41 into the corresponding socket 21, thereby fixing the adjusting block 2, and re-fix the position of the slider 42 with the locking rod 44 to complete the adjustment.
