DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] Example 1: Please refer to Figure 1-4 , an anti-loosening structure of an adjustable wrench, comprising a wrench body 1, a fixing member 2 is fixedly connected to the rear end of the left side of the wrench body 1, a reserved groove 4 is provided at the front end of the left side inside the fixing member 2, a movable plate 7 is installed inside the reserved groove 4, a movable member 8 is fixedly connected to the rear end of the left side of the movable plate 7, a groove 11 is provided inside the fixing member 2, mounting holes 5 are provided at both ends of the groove 11, a fixed shaft 9 is provided inside the mounting hole 5, an adjusting wheel 6 is provided outside the fixed shaft 9, a step 12 is fixedly connected inside the adjusting wheel 6, and a spring 10 is provided at one end of the step 12;

[0026] The outer circle of the step 12 is larger than the outer circle of the spring 10, the length of the spring 10 is larger than the depth of the step 12, the adjusting wheel 6 is arranged inside the groove 11 through the fixed shaft 9, the adjusting wheel 6 is movably connected inside the groove 11, the movable plate 7 is arranged inside the reserved groove 4, the movable plate 7 and the adjusting wheel 6 cooperate with each other, the spring 10 is arranged inside the adjusting wheel 6, and the spring 10 and the adjusting wheel 6 cooperate with each other;

[0027] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, a step 12 is provided inside the adjusting wheel 6, and the length of the spring 10 is greater than the depth of the step 12, that is, the spring 10 can be higher than the step 12 after being placed on the step 12. After the whole is installed inside the adjusting wheel 6 and connected in series with the fixed shaft 9, the higher spring 10 will press against the step 12, thereby preventing the step 12 from loosening and accidentally rotating the movable plate 7 to move the distance between the adjusting movable part 8 and the fixed part 2.

[0028] Embodiment 2: The inner side walls of the fixed member 2 and the movable member 8 are provided with an anti-skid plate 3, one end of the anti-skid plate 3 near the middle position is provided with an anti-skid pad 13, one end of the anti-skid plate 3 near the outside is provided with a first magnetic block 14, the inside of the fixed member 2 and the movable member 8 are respectively provided with mounting grooves 15, the inside of the mounting grooves 15 is fixedly connected with a second magnetic block 16, the anti-skid plate 3 is provided with two groups, and the first magnetic block 14 is provided inside the mounting grooves 15;

[0029] Specifically, Figure 1 and Figure 4 As shown, the anti-skid pad 13 can not only prevent the movable part 8 and the fixed part 2 from sliding when the wrench body 1 is used, but also protect the fixed part 2 and the movable part 8, reducing the wear of the fixed part 2 and the movable part 8 when in use. The provision of the anti-skid plate 3 and the anti-skid pad 13 can facilitate the user to use the wrench body 1.

[0030] Embodiment 3: The first magnetic block 14 and the second magnetic block 16 cooperate with each other, and the anti-slip plate 3 is installed on the fixed part 2 and the movable part 8 through the first magnetic block 14 and the second magnetic block 16;

[0031] Specifically, Figure 1 and Figure 4 As shown, the first magnetic block 14 at one end of the anti-skid plate 3 is placed inside the mounting groove 15. Since the first magnetic block 14 and the second magnetic block 16 inside the mounting groove 15 cooperate with each other, the first magnetic block 14 can be installed inside the mounting groove 15, so that the anti-skid plate 3 can be installed. When the anti-skid pad 13 needs to be replaced, the anti-skid plate 3 is pulled to make the first magnetic block 14 detach from the mounting groove 15 to disassemble the anti-skid pad 13. After disassembly, take a new anti-skid plate 3 and install it on one end of the fixing member 2.

[0032] Working principle: When the utility model is in use, a step 12 is arranged inside the adjusting wheel 6, and the length of the spring 10 is greater than the depth of the step 12, that is, the spring 10 can be higher than the step 12 after being placed on the step 12. After the whole is installed inside the adjusting wheel 6 and the fixed shaft 9 is connected in series, the spring 10 is higher and will press against the step 12, thereby preventing the step 12 from loosening and accidentally rotating the movable plate 7 to move the distance between the adjusting movable part 8 and the fixed part 2. After adjustment, the bolt can be screwed conveniently. When screwing the bolt, the anti-slip pad 13 can not only prevent the use of a wrench to When the main body 1 is in use, the movable part 8 and the fixed part 2 will slide, and the fixed part 2 and the movable part 8 can also be protected to reduce the wear of the fixed part 2 and the movable part 8 during use. When the anti-slip pad 13 needs to be replaced, the anti-slip plate 3 is pulled to make the first magnetic block 14 disengage from the inside of the installation groove 15 to disassemble the anti-slip pad 13. After disassembly, a new anti-slip plate 3 can be installed on one end of the fixed part 2. Since the first magnetic block 14 and the second magnetic block 16 inside the installation groove 15 cooperate with each other, the first magnetic block 14 can be fixed inside the installation groove 15.
