AI Technical Summary
It is difficult for existing wrenches to apply effective torque in a narrow space, especially when the nut is at an inclined angle.
A long-axis wrench is designed, which includes an adjustable wrench head, a shaft, a handle rod and a limiter. The adjustable wrench head can move axially along the shaft rod and is fixed in position by the limiter. The handle rod drives the shaft rod to rotate the adjustable wrench head, thereby adjusting the position of the wrench head opening to adapt to nuts of different sizes.
It realizes the application of torque outside the narrow space, can effectively screw nuts of different sizes, and adapt to the operation needs in the narrow space.

Description
TECHNICAL FIELD
[0001] The utility model relates to a wrench tool, especially a wrench for narrow space. BACKGROUND
[0002] The existing wrench is difficult to use force in narrow space, especially when the nut has an inclined angle. To solve the above problems, a wrench capable of using force in narrow space and having adjustable front and back positions of the wrench head is needed. SUMMARY
[0003] The utility model solves the technical problem of providing a long shaft wrench.
[0004] To achieve the above purpose, the utility model provides the following technical scheme:
[0005] A long shaft wrench is composed of a movable wrench head, a shaft rod, a handle rod and a stopper. The movable wrench head has a butt joint hole, which is sleeved in the end region of the shaft rod. The movable wrench head can be axially moved and adjusted in position along a certain region of the end of the shaft rod, and is fixed in position radially relative to the shaft rod. The stopper is fixed on the shaft rod to fix the position of the movable wrench head in the axial direction of the shaft rod. The other end of the shaft rod is connected with the handle rod, and the handle rod drives the shaft rod to rotate, thereby driving the movable wrench head to rotate. The movable wrench head has a wrench head opening, which can be an open wrench head or a closed open wrench head (such as a plum blossom wrench head).
[0006] The movable wrench head has two wrench head openings of different sizes in opposite directions, and two butt joint holes, each of which is used in cooperation with a non-adjacent wrench head opening.
[0007] The movable wrench head has three wrench head openings of different sizes, and the three wrench head openings share one butt joint hole. BRIEF DESCRIPTION OF DRAWINGS

[0010] BRIEF DESCRIPTION OF DRAWINGS
[0011] 1. Movable wrench head; 2. Shaft rod; 3. Handle rod; 4. Butt joint hole; 5 Open wrench head; 6. Stopper; 7. Air conditioner three-way valve; 8. Nut DETAILED DESCRIPTION
[0012] The utility model will be further described in detail in combination with the drawings.
[0013] Figure 1The first embodiment of the utility model is used for installing the nut nut of the air conditioner outdoor unit, and the handle rod is outside the narrow space.
[0014] A long axis spanner is composed of a movable spanner head 1, a shaft rod 2, a handle rod 3 and a position limiter 6. The movable spanner head 1 has a butt joint hole 4, the butt joint hole 4 is sleeved in the end region of the shaft rod 2, the movable spanner head 1 can be axially moved and adjusted in position along the certain region of the end of the shaft rod 2, the movable spanner head 1 is fixed in position radially relative to the shaft rod 1, the position limiter 6 is fixed on the shaft rod 2 to fix the position of the movable spanner head 1 in the axial direction of the shaft rod 2, the other end of the shaft rod 2 is connected with the handle rod 3, the handle rod 3 rotates to drive the shaft rod 2, thereby driving the open spanner head 5 on the movable spanner head 1 to rotate the nut nut 8 of the air conditioner three-way valve 7, thereby achieving the forceful rotation of the movable spanner head 1 in the narrow space outside the narrow space.
[0015] The movable spanner head 1 has two opposite direction open spanner heads 5 with different sizes, and has two butt joint holes 4, each butt joint hole 4 is used in cooperation with the non-adjacent open spanner head 5. The direction of the movable spanner head 1 is converted to twist the two sizes of the nut nut 8 of the air conditioner outdoor unit.
[0016] The movable spanner head 1 has three open spanner heads 5 with different sizes, and the three open spanner heads 5 share one butt joint hole 4. The radial angle is adjusted by disassembling and assembling the movable spanner head 1, and the three sizes of the nut nut 8 can be twisted.
