DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0024] As Figures 1 to 5 shown, the utility model provides a kind of innovative wrench for accurate positioning, including wrench rod 1, the surface of wrench rod 1 is equipped with cross assembly 2;

[0025] Cross assembly 2 includes cross handle 21, the top end of wrench rod 1 is equipped with cross handle 21, the bottom of wrench rod 1 is provided with connecting column 22, the bottom end of connecting column 22 is equipped with cross torsion block 23, the top end of connecting column 22 is equipped with metal sleeve 24, wrench rod 1 is slidably connected in the inside of metal sleeve 24, the surface of metal sleeve 24 is equipped with position positioning assembly 3, the cross torsion block 23 of connecting column 22 bottom can be adapted with the protective cover flower groove on battery, to further when the protective cover is disassembled, avoid when the protective cover of battery is disassembled, easy to damage the flower groove on protective cover, can be rotated by cross handle 21 and cross torsion block 23 are handled, cross handle 21 can make operator more convenient when screwing, it is convenient for operator to easily screw cross torsion block 23, further improve the efficiency of the overall operation of wrench.

[0026] Specifically, the four end surfaces of cross handle 21 are each provided with a thread groove 25 for anti-skid, so that anti-skid can be performed when cross handle 21 is screwed.

[0027] As Figures 1 to 5 shown, metal sleeve 24 and wrench rod 1 are made of steel material, for strengthening the strength of the whole, and the inner wall thickness of metal sleeve 24 is relatively thick.

[0028] Further, reinforcing ribs are installed inside cross torsion block 23 for improving the overall strength of cross torsion block 23.

[0029] As Figures 1 to 5As shown, the position positioning assembly 3 comprises a connecting block 31, the surface of the metal sleeve 24 is provided with the connecting block 31, the inside of the connecting block 31 is slidably connected with a positioning rod 32, one end of the positioning rod 32 penetrates the connecting block 31 and the metal sleeve 24 in sequence, and is inserted into the insertion hole opened on the surface of the wrench rod 1. The surface of the wrench rod 1 is provided with a plurality of insertion holes for positioning different positions.

[0030] Further, the surface of the positioning rod 32 is sleeved with a reset spring 33, one end of the reset spring 33 is connected with the positioning rod 32, and the other end of the reset spring 33 is mounted in the inside of the connecting block 31. The reset spring 33 can reset the moving position of the positioning rod 32, thereby facilitating the adjustment of the length of the wrench.

[0031] It is worth emphasizing that the surface of the positioning rod 32 is provided with an adjusting handle 34, the surface of the connecting block 31 is provided with a sliding groove matched with the adjusting handle 34, the adjusting handle 34 is slidably connected in the sliding groove, and a damping strip 35 is mounted in the sliding groove for damping the adjusting handle 34, so as to facilitate the operator to adjust the length of the wrench rod 1, and the damping strip 35 can stabilize the position of the adjusting handle 34.

[0032] Working principle and process: when the operator uses the wrench as a whole, the cross-shaped twist block 23 at the bottom of the connecting column 22 can be matched with the flower groove on the protective cover of the battery, so as to avoid damaging the flower groove on the protective cover when disassembling the protective cover of the battery, thereby affecting the disassembly effect of the protective cover, and the operator can drive the cross-shaped twist block 23 to rotate by the cross-shaped handle 21 during use, so that the cross-shaped handle 21 can make the operator more convenient when twisting, so that the operator can easily twist the cross-shaped twist block 23, and further improve the operation efficiency of the wrench as a whole.

[0033] When the length of the wrench is short and needs to be adjusted, first the operator pushes the adjusting handle 34, and the pushing force is greater than the resistance of the damping strip 35. At this time, the adjusting handle 34 slides in the sliding groove on the surface of the connecting block 31. The adjusting handle 34 drives the positioning rod 32 to move inside the connecting block 31 during the sliding process. As the positioning rod 32 continuously moves, the positioning rod 32 drives the reset spring 33 to deform. The reset spring 33 can reset the moving position of the positioning rod 32, thereby facilitating the adjustment of the length of the wrench. At this time, the positioning rod 32 is separated from the insertion hole on the surface of the wrench rod 1, and then the wrench rod 1 is pulled to slide inside the metal sleeve 24, thereby adjusting the length of the wrench rod 1, thereby adapting to different use scenarios and reducing the limitations of the wrench in use. When the length adjustment of the wrench rod 1 is completed, the operator releases the adjusting handle 34. The reset spring 33 drives the positioning rod 32 to insert into the insertion hole on the surface of the wrench rod 1. The multiple insertion holes on the surface of the wrench rod 1 can realize positioning when the wrench rod 1 moves to different positions.
