[0041] When the present invention is in use, through the combined design of the wrench rod 2 and the auxiliary rod 4, a striking hammer 5 is provided at one end of the original wrench, so that when the bolt is rusted, the person can hold the wrench rod 2 and use the bolt clamping groove on the wrench body 1 to clamp the nut, and use the part of the striking hammer 5 to strike the safe smooth surface of the wrench rod 2, so as to loosen the nut. At this time, it is more convenient to remove the bolt, the structure is simple, and the practicability is strong; in addition, the striking hammer 5 mentioned above is not limited to disassembling nuts, and can also be used to strike sharp objects such as nails.

[0042] Furthermore, the wrench body 1 and the wrench rod 2 are in an L-shaped structure as a whole, the auxiliary rod 4 is arranged in the L-shaped angle formed by the wrench body 1 and the wrench rod 2, and the side of the auxiliary rod 4 away from the wrench rod 2 is matched with the side of the wrench body 1. When the wrench rod 2 and the auxiliary rod 4 are assembled, the side of the wrench body 1 away from the wrench rod 2 can be matched with the side of the auxiliary rod 4, thereby forming an overall smooth side, which is convenient for manual holding.

[0043] Furthermore, the auxiliary rod 4 is in an L-shaped structure, the wrench rod 2 is arranged in a snug fit within the L-shaped angle of the auxiliary rod 4, and the upper side of the wrench rod 2 is consistent with the other side of the auxiliary rod 4. Similarly to the above, an overall smooth side surface is formed between the end of the auxiliary rod 4 away from the wrench body 1 and the wrench rod 2, so that when the wrench rod 2 and the auxiliary rod 4 are assembled, the two can form a complete wrench, which is no different from the common wrenches in the prior art.

[0044] Furthermore, a first positioning block 13 is provided on the end surface of the wrench rod 2 facing the auxiliary rod 4, and a first positioning groove 14 is provided at a position of the auxiliary rod 4 corresponding to the wrench rod 2, and the first positioning block 13 can be inserted into the first positioning groove 14. Although the present invention imposes certain restrictions on the T-shaped slider 8 through the slide groove 11 to prevent the wrench rod 2 from being separated from the auxiliary rod 4, the first positioning block 13 and the second positioning groove can improve the connection strength between the wrench rod 2 and the auxiliary rod 4.

[0045] Furthermore, a second positioning block 26 is provided on the end surface of the auxiliary rod 4 facing the wrench body 1, and a second positioning groove is provided at the position of the wrench body 1 corresponding to the auxiliary rod 4, and the second positioning block 26 can be inserted into the second positioning groove. In implementation, similarly to the above, when the first positioning block 13 is inserted into the first positioning groove 14, the second positioning block 26 is inserted into the second positioning groove, and the clamping block 16 can be inserted into the first clamping groove 17, so that the wrench rod 2 and the auxiliary rod 4 are completely matched, so that a complete wrench can be formed between the wrench rod 2 and the auxiliary rod 4, ensuring that there is no difference with the common wrenches in the prior art.

[0046] Furthermore, a first mark 9 is provided on the front or back of the wrench bar 2, and a second mark 10 is provided on the auxiliary bar 4 on the same side as the first mark 9; and when the first mark 9 and the second mark 10 correspond to each other, the T-shaped slider 8 corresponds to the bayonet 12. When the first mark 9 on the wrench bar 2 and the second mark 10 on the auxiliary bar 4 are aligned, part of the T-shaped slider 8 can be removed from the bayonet 12, and the disassembly operation of the wrench bar 2 and the auxiliary bar 4 can be completed. Similarly, when installing, when the first mark 9 on the wrench bar 2 and the second mark 10 on the auxiliary bar 4 are aligned, part of the T-shaped slider 8 can be inserted into the bayonet 12. The first mark 9 and the second mark 10 in the present invention can be respectively set on the front or back of the wrench bar 2 and the auxiliary bar 4, as long as the two are located on the same side.

[0047] Furthermore, a limiting groove 24 is further provided on the side of the T-shaped slider 8 facing the auxiliary rod 4, and the elastic groove 23 is located inside the limiting groove 24 and connected to the limiting groove 24, and the diameter of the limiting groove 24 is equal to the diameter of the clamping block 16 and is larger than the diameter of the elastic groove 23. The limiting groove 24 limits the clamping block 16 to prevent the connecting hole from pulling the connecting rod 15 and the clamping block 16 too deep, and when the clamping block 16 is pulled into the limiting groove 24 by the connecting hole, the clamping block 16 can be completely separated from the first clamping groove 17, even if part of the clamping block 16 is located outside the T-shaped slider 8, so as to prevent the clamping block 16 from hindering the movement of the T-shaped slider 8 in the sliding cavity 3; in addition, the elastic groove 23, the limiting groove 24, the clamping block 16 and other structures in the present invention are not limited to cylindrical shapes, and can also be rectangular column structures, and their lengths and widths can remain corresponding to each other.

[0048] Furthermore, a plurality of second slots 18 are provided on the side of the auxiliary rod 4 away from the wrench rod 2, and the second slots 18 and the first slots 17 are out of position with the bayonet 12, and the block 16 can be inserted into different second slots 18 to adjust the connection length between the auxiliary rod 4 and the wrench rod 2. The present invention can also make the grip torque of the wrench of the present invention adjustable by the relative sliding design between the wrench rod 2 and the auxiliary rod 4, and the clamping effect of the block 16 in different second slots 18. The staff can adjust the wrench rod 2 and the auxiliary rod 4 to a suitable length according to the actual situation, so as to facilitate the hand-held operation of the staff, and further improve the performance of the wrench. However, it should be noted that the position of the second slot 18 cannot correspond to the bayonet 12, that is, the second slot 18 is out of position with the bayonet 12, so as to avoid the wrench rod 2 from being separated from the auxiliary rod 4 through the bayonet 12.

[0049] Furthermore, it also includes a lubrication assembly, which includes a liquid storage box 6, an air bag bulge 19 and a sealing cover 22. The liquid storage box 6 is arranged on the other side of the auxiliary rod 4 away from the percussion hammer 5, and the air bag bulge 19 is arranged on the side wall of the liquid storage box 6. The wall surface of the liquid storage box 6 is provided with an air port 20 that communicates with the air bag bulge 19; an oil outlet nozzle 21 is arranged at one end of the liquid storage box 6, and the sealing cover 22 is sleeved on the oil outlet nozzle 21. The present invention can use the lubricating liquid in the liquid storage box 6 to apply lubricating liquid to rusty bolts during maintenance operations, so that when the percussion hammer 5 strikes the wrench rod 2, it is convenient to loosen the bolts or nuts more quickly; in addition, the lubrication assembly can also be used to lubricate parts other than bolts, and then the percussion hammer 5 can be used to perform percussion and tightening operations on the corresponding structure, thereby increasing the use function of the original wrench.

[0050] Furthermore, the sealing cover 22 is connected to the liquid storage box 6 via a connecting line 27 to prevent the sealing cover 22 from being lost.

[0051] During the use of the present invention, when it is necessary to tighten the bolt, the personnel hold the wrench rod 2 and the auxiliary rod 4, and cooperate with the design of the screw opening on the wrench body 1 to complete the above operation;

[0052] When encountering rusted bolts, remove the sealing cover 22 at the oil nozzle 21 on the liquid storage box 6 on one side of the auxiliary rod 4, and press the part of the airbag bulge 19, so that the lubricant originally stored in the liquid storage box 6 can be sprayed on the rusted bolts, thereby providing safe and favorable conditions for the subsequent use of the wrench body 1 to tighten the nut. At the same time, the connecting block 7 can be pulled to move part of the connecting block 7 outward. At this time, the clamping block 16 is pulled from the first clamping groove 17 to the limiting groove 24, and the part of the spring 25 is in a compressed state. Then, the part of the T-shaped sliding block 8 on the bottom side of the wrench rod 2 is moved in the sliding groove 11 and the sliding cavity. 3, the first positioning blocks 13 and the second positioning blocks 26 at the ends of the wrench rod 2 and the auxiliary rod 4 are disengaged from the corresponding first positioning grooves 14 and the second positioning grooves. When the first mark 9 on the wrench rod 2 and the second mark 10 on the auxiliary rod 4 are aligned, the part of the T-shaped slide block 8 is removed from the bayonet 12, and the disassembly operation of the wrench body 1, the wrench rod 2 and the auxiliary rod 4 can be completed. At this time, the personnel holds the wrench rod 2 and uses the wrench body 1 to clamp the nut, and uses the part of the hammer 5 to knock on the safety smooth surface on the wrench rod 2 to loosen the nut, so that it is more convenient to screw and remove the bolt.

[0053] When it is necessary to knock other objects, the knocking hammer 5 can be used directly for knocking. At the same time, the lubricating liquid in the liquid storage box 6 described above can be used to lubricate the parts other than the bolts that need lubrication during the maintenance work, which is highly practical.

[0054] During actual operation, the personnel can fold and move part of the block 16 according to the above method, so that part of the block 16 is engaged with the corresponding second slot 18, so that the grip torque of the wrench of the present invention can be adjusted. The staff can adjust the wrench rod 2 and the auxiliary rod 4 to a suitable length according to the actual situation, so as to facilitate the personnel to hold the operation, thereby ensuring the safe and efficient use of the wrench for auxiliary disassembly and maintenance of electrical appliances.
