[0040] The second spring 602 provides a restoring force for the second locking block 601.
[0041] Furthermore, a first half-ring groove is formed on the secondary handle 3 for cooperating with the convex ring 101. One end of the first half-ring groove is provided with a first sliding groove for the first locking block 401 to slide. The first sliding groove limits the movement track of the first locking block 401, and a first slot hole is formed at one end of the first sliding groove.
[0042] A communication groove is formed on the secondary handle 3, and the communication groove is communicated with the first slot hole.
[0043] Furthermore, a locking groove is formed on the connecting block 301 for cooperating with the second locking block 601.
[0044] Furthermore, a second half-ring groove is formed on the mounting half-ring 5 for cooperating with the convex ring 101.
[0045] The two ends of the mounting half-ring 5 extend with spreading blocks 501. A receiving groove is formed on the spreading block 501 for cooperating with the connecting block 301.
[0046] A second sliding groove is formed in the receiving groove for the second locking block 601 to slide. The second sliding groove limits the movement track of the second locking block 601, and a second slot hole is formed at one end of the second sliding groove.
[0047] A connecting groove is further formed on the spreading block 501, and the connecting groove is communicated with the second slot hole.
[0048] During combination, the first half-ring groove and the second half-ring groove are combined to form a complete ring and can make a circumferential movement under the limitation of the convex ring 101.
[0049] Further, as Figure 8 shown, a first connecting rod 403 is installed on the first locking block 401. The first connecting rod 403 is slidably arranged in the first slot hole. One end of the first connecting rod 403 is installed with a first operating block 404, and the first operating block 404 is slidably arranged in the communication groove.
[0050] Further, one end of the first spring 402 is installed in the first chute, and the other end is connected to the first locking block 401.
[0051] Further, as Figure 9 shown, a second connecting rod 603 is installed on the second locking block 601. The second connecting rod 603 is slidably arranged in the second slot hole. One end of the second connecting rod 603 is installed with a second operating block 604.
[0052] Further, the second operating block 604 is slidably arranged in the connecting groove.

[0054] A compact lithium - electric wrench has the following working principle:
[0055] To match different states, there are the following operations:
[0056] Adjust the angle of the sub - grip to match different holding angles:
[0057] First, pull the first operating block 404, drive the first operating rod to move, and then drive the first locking block 401 to move, so that the first locking block 401 disengages from the locking groove and compresses the first spring 402, releasing the lock between the sub - handle 3 and the convex ring 101. Then, the sub - handle 3 can be operated to rotate under the limit of the convex ring 101. After rotating to an appropriate angle, release the first operating block 404. Under the action of the first spring 402, the first locking block 401 is pushed, and the first locking block 401 is pushed into the interior of the locking groove to complete the adjustment;
[0058] When disassembling the sub - handle 3:
[0059] Pull the second operating block 604, drive the second connecting rod 603 to move, and the second connecting rod 603 drives the second locking block 601 to move, so that the second locking block 601 disengages from the locking groove, releasing the lock between the connecting block 301 and the spreading block 501. At this time, the sub - handle 3 can be separated from the mounting half - ring 5, and the sub - handle 3 and the mounting half - ring 5 can be removed from the wrench body 1;
[0060] When installing the sub - handle 3:
[0061] Operate the auxiliary handle 3 to move the connecting block 301 on the auxiliary handle 3 into the receiving groove. When the connecting block 301 contacts the second locking block 601, the second locking block 601 is forced to move into the second sliding groove and squeeze the second spring 602 until the connecting block 301 is completely inserted into the receiving groove. The locking groove on the connecting block 301 corresponds to the position of the second sliding groove. Under the action of the second spring 602, the second locking block 601 is pushed to move, so that the second locking block 601 is inserted into the locking groove to complete the installation.
