[0024] The embodiment of the present application provides a new type of forward and reverse adjustable wrench, which effectively solves the problem in the prior art that when using a wrench for tightening and disassembling operations, the wrench must be applied in two different directions, clockwise and counterclockwise, respectively. However, during the operation, for people who are accustomed to using their right hand, it is more convenient to use the wrench when applying force clockwise, but it is more inconvenient to use the wrench when applying force counterclockwise. Only by rotating the movable handle under clockwise force, the rotating disk and the fixed disk can be relatively rotated around the rotating axis, and the internal gear and the external gear can respectively engage with the rotating gear to complete the clockwise and counterclockwise rotation of the sleeve mounting hole, respectively, so that the forward and reverse operations of the bolts and nuts can be completed only by rotating the wrench under clockwise force, making the tightening and disassembly operations more convenient and handy. Example

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that when using a wrench for tightening and disassembling operations in the prior art, force must be applied in two different directions, clockwise and counterclockwise, respectively. However, during the operation, for people who are accustomed to using their right hand, it is more convenient to use the wrench when force is applied clockwise, but it is more inconvenient to use the wrench when force is applied counterclockwise. The overall idea is as follows: A new type of forward and reverse adjustable wrench, including a rotating disk 1, a fixed disk 2, a buckle 7, a ratchet mechanism 11, a sleeve mounting hole 12 and a ratchet steering adjuster 13. A movable handle 6 is installed on the center line of one side of the rotating disk 1 through two buckles 7. On the inner side of the flange edge on the other side of the rotating disk 1 is an internal gear 4 with 1 / 3 circle teeth. An external gear 5 with 1 / 3 circle teeth is fixedly installed at the center of the rotating disk 1. The teeth of the internal gear 4 and the external gear 5 are respectively arranged on both sides of the horizontal line where the center line of the movable handle 6 is located. The teeth are arranged symmetrically with respect to the center line of the rotating disk 1 which is perpendicular to the movable handle 6. A rotating shaft 14 is provided at the center of the fixed disk 2. The fixed disk 2 is connected to the center of the rotating disk 1 through the rotating shaft 14. The fixed disk 2 and the rotating disk 1 can rotate relative to each other through the rotating shaft 14. A fixed handle 3 and a rotating gear 8 are provided on one side of the fixed disk 2. The center line of the fixed handle 3 and the center of the rotating gear 8 and the center of the rotating shaft 14 are located on the same horizontal line. Circular slide grooves 10 are equidistantly provided on the inner wall of the rotating gear 8. Stabilizing rods 9 are equidistantly provided on the fixed disk 2. The stabilizing rod 9 is slidably engaged with the circular slide grooves 10. A sleeve mounting hole 12 is provided at the center of the rotating gear 8. The rotating gear 8 is connected to the sleeve mounting hole 12 through a ratchet mechanism 11. A ratchet steering adjuster 13 is provided on the ratchet mechanism 11. The ratchet mechanism 11 can control the rotation of the sleeve mounting hole 12 through the ratchet steering adjuster 13.

[0026] In view of the problems existing in the prior art, the utility model provides a new type of forward and reverse adjustable wrench, which can make the rotating disk and the fixed disk rotate relative to each other with the rotating axis as the center only by rotating the movable handle clockwise under force, and the internal gear and the external gear respectively engage with the rotating gear to complete the clockwise and counterclockwise rotation of the sleeve mounting hole respectively, so that the forward and reverse rotation of the bolt and nut can be completed only by rotating the wrench clockwise under force, making the tightening and disassembly operations more convenient and smooth.

[0027] Working principle:

[0028] The first step is to turn the bolt and nut clockwise by moving the movable handle 6 from Figure 1 The position moves to the maximum travel position at the other end, reaching Figure 2Position, put the sleeve into the sleeve mounting hole 12, put the bolt and nut into the sleeve, adjust the ratchet steering adjuster 13 to the clockwise force rotation position of the sleeve mounting hole 12, hold the fixed handle 3 with the left hand, hold the movable handle 6 with the right hand, turn the movable handle 6 clockwise, so that the rotating disk 1 and the fixed disk 2 rotate relative to each other with the rotating shaft 14 as the center, and the internal gear 4 and the rotating gear 8 engage to complete the clockwise rotation of the sleeve mounting hole 12. When the movable handle 6 is quickly turned to the position of the fixed handle 3, turn the movable handle 6 counterclockwise to return to the fixed position. Figure 2 During this process, under the action of the ratchet mechanism 11, the sleeve mounting hole 12 does not rotate, and the movable handle 6 is basically not subject to resistance. The movable handle 6 is moved back and forth to achieve the clockwise rotation of the bolt and the nut.

[0029] Step 2: When the bolt or nut needs to be turned counterclockwise, move the movable handle 6 from Figure 1 The position is rotated 180° around the rotation axis 14 to reach Figure 6 Position, put the sleeve into the sleeve mounting hole 12, put the bolt and nut into the sleeve, adjust the ratchet steering adjuster 13 to the counterclockwise force rotation position of the sleeve mounting hole 12, hold the fixed handle 3 with the left hand, hold the movable handle 6 with the right hand, turn the movable handle 6 clockwise to make the rotating disk 1 and the fixed disk 2 rotate relative to each other around the rotating shaft 14, and the circumscribed gear 5 and the rotating gear 8 engage to complete the counterclockwise rotation of the sleeve mounting hole 12. When the movable handle 6 is quickly turned to the position of the fixed handle 3, turn the movable handle 6 counterclockwise to return to the fixed handle 3 position. Figure 6 During this process, under the action of the ratchet mechanism 11, the sleeve mounting hole 12 does not rotate, and the movable handle 6 is basically not subject to resistance. The movable handle 6 is moved back and forth to achieve counterclockwise rotation of the bolt and nut.

[0030] 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.
