[0031] The embodiment of the present application provides an easily adjustable nut tightening device, which effectively solves the technical problem that the length of the handle cannot be adjusted due to a certain length of the handle, resulting in the nut being unable to accommodate the hand holding the handle to rotate when the environment in which the nut is located is relatively narrow. At this time, it is difficult for the staff to unscrew the nut without other tools, which affects the work progress of the staff.

[0032] Example

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the length of the handle 2 cannot be adjusted due to the fixed length of the handle 2, resulting in that when the nut is in a narrow environment and cannot accommodate the hand holding the handle 2 to rotate, it is difficult for the staff to unscrew the nut without other tools, which affects the work progress of the staff. The overall idea is as follows:

[0034] In view of the problems existing in the prior art, the utility model provides a nut tightening device that is easy to adjust, the nut tightening device that is easy to adjust comprises a wrench head 1, a handle 2 is arranged outside the wrench head 1, a connecting block 3 is fixedly installed on one side of the wrench head 1 close to the handle 2, a plurality of fixing blocks 4 are fixedly installed outside the connecting block 3, and a connecting mechanism is arranged on one side of the handle 2 close to the wrench head 1;

[0035] The connecting mechanism includes a slide groove 5, a slot 6, a support plate 7, a spring 8 and a baffle 9;

[0036] The slide groove 5 is provided on a side of the handle 2 close to the wrench head 1, the slot 6 is provided on the outside of the handle 2, the slot 6 is communicated with the slide groove 5, there are two support plates 7, the two support plates 7 are fixedly mounted inside the slot 6, there are two springs 8, the two springs 8 are respectively fixedly mounted on the outside of the two support plates 7, the two ends of the baffle plate 9 are respectively fixedly connected to the outside of the two springs 8, the baffle plate 9 is fitted with the fixed block 4, and the baffle plate 9 is located between the two fixed blocks 4;

[0037] The connecting block 3 is slidably connected inside the sliding groove 5 .

[0038] When the user needs to adjust the length of the wrench, the baffle plate 9 is pulled so that the baffle plate 9 and the fixing block 4 are no longer in contact with each other. At this time, the spring 8 is stretched under the movement of the baffle plate 9, and the wrench is pulled so that the wrench head 1 drives the connecting block 3 to be pulled toward the outside of the slide slot 5, so that the length of the connecting block 3 and the handle 2 is increased. When the length of the connecting block 3 and the handle 2 increases to the user's use requirement, the baffle plate 9 is loosened. Under the action of the spring 8, the baffle plate 9 and the fixing block 4 are in contact with each other under the action of the spring 8. At this time, the baffle plate 9 is located between the two fixing blocks 4 to fix the connecting block 3. At this time, the user can fit the wrench head 1 with the nut, hold the end of the handle 2 away from the wrench head 1 by hand, and rotate it to unscrew the nut. By adjusting the length of the handle 2 and the connecting block 3, the user can rotate by holding the handle 2 away from the environment where the nut is located, so as to avoid that when the environment where the nut is located is relatively narrow and cannot accommodate the hand holding the handle 2 for rotation, it is difficult for the staff to unscrew the nut without other tools, thereby affecting the staff's work process.

[0039] A connecting shaft 10 is fixedly mounted on the outside of each support plate 7;

[0040] The spring 8 is movably sleeved on the outside of the connecting shaft 10 to limit the moving path of the spring 8 .

[0041] Both ends of the baffle plate 9 are provided with circular grooves 11;

[0042] The baffle plate 9 is slidably connected to the outside of the connecting shaft 10 through the circular groove 11 to prevent the connecting shaft 10 from affecting the sliding of the baffle plate 9 .

[0043] A limiting groove 12 is formed on the outside of the connecting block 3, and a limiting block 13 is fixedly installed inside the sliding groove 5;

[0044] The limiting block 13 is slidably connected to the inside of the limiting groove 12 to prevent the connection block 3 from being separated from the sliding groove 5 and causing the wrench head 1 to fall when the device is not in use.

[0045] A handle 14 is provided on the outside of the handle 2;

[0046] Among them, the handle 2 is rotatably connected to a rotating shaft 15 on one side close to the handle 14, and the handle 14 is fixedly connected to the outside of the rotating shaft 15 to facilitate the user to unscrew the nut when the nut is on a larger plane.

[0047] A placement groove 16 is provided on one side of the handle 2 close to the rotating shaft 15;

[0048] The rotating shaft 15 is rotatably connected to the inside of the placement groove 16, and the handle 14 is placed inside the placement groove 16, which is convenient for placing the handle 14 when not in use.

[0049] By setting the handle 14 outside the handle 2 in cooperation with the fixed shaft, when the nut is on a larger plane, the wrench head 1 can be fitted with the nut. At this time, the handle 14 is turned upward to make the handle 14 upright. By holding the handle 14 to drive the handle 2, the handle 2 drives the wrench head 1 so that the handle 2 unscrews the nut, which is convenient for the user to unscrew the nut with less effort when the nut is on a larger plane.

[0050] Working principle:

[0051] The first step is to cooperate with the baffle plate 9 by setting the fixing block 4 outside the connecting block 3. When the overall length of the wrench needs to be adjusted, the baffle plate 9 is pulled so that the baffle plate 9 and the fixing block 4 are no longer fitted. At this time, the spring 8 is stretched under the movement of the baffle plate 9. At this time, the wrench head 1 is pulled so that the wrench head 1 drives the connecting block 3 to be pulled to the outside of the slide slot 5. The wrench head 1 slides to increase the length of the connecting block 3 and the handle 2. When the length of the connecting block 3 and the handle 2 increases to the user's use requirement, the baffle plate 9 is released. Under the action of the spring 8, the baffle plate 9 and the fixing block 4 are fitted. At this time, the baffle plate 9 is located between the two fixing blocks 4 to fix the connecting block 3. At this time, the wrench head 1 is fixed. At this time, the user can fit the wrench head 1 with the nut, hold the handle 2 away from the end of the wrench head 1, and rotate it to unscrew the nut.

[0052] In the second step, if the nut is on a larger plane, the wrench head 1 can be fitted with the nut, and the handle 14 is turned upward to make the handle 14 upright. By holding the handle 14, the handle 2 is driven, and the handle 2 drives the wrench head 1 so that the handle 2 can unscrew the nut.

[0053] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
