[0023] See also Figure 1-3As shown, a matching wrench that can be used for hardware with an expansion end includes a torsion bar 1, the bottom end of the torsion bar 1 is fixedly connected to the sleeve 2, the slide groove of the groove of the torsion bar 1 is slidably connected to the sliding plate 10, the through hole of the side wall of the sliding plate 10 is plugged into the vertical plate 8, the vertical plate 8 is fixedly connected to the side wall of the push rod 6, and the push rod 6 slides and extends into the sleeve 2 and is fixedly connected to the impact plate 5.

[0024] The inner wall of the sleeve 2 is provided with a hexagonal groove, which is convenient for removing the limit nut when twisting the torsion bar 1 through the action of the hexagonal groove. The outer wall of the torsion bar 1 is fixedly connected to the collar 3, and both sides of the collar 3 are fixedly connected to the grip bar, and the outer wall of the grip bar is provided with a plurality of convex points, which are convenient for improving the friction between the grip bar and the palm through the action of the convex points. The torsion bar 1 is threadedly connected to the connecting pipe 4, and the inner wall of the sleeve 2 is slidably connected to the sliding rod 14. The I-shaped rod fixedly connected to the bottom end of the sliding rod 14 is rotatably connected to the rotating plate 13. The bottom of the rotating plate 13 is fixedly connected to the four columns 12 in a symmetrical form, and the bottom end of the column 12 is fixedly connected to the top of the U-shaped rod 11 The U-shaped rod 11 is fixedly connected with the plug-in block at the bottom center, the through hole on the side wall of the vertical plate 8 is plugged with the cross bar 9, and the cross bar 9 is fitted with the top of the sliding plate 10. The top of the cross bar 9 is provided with a plug-in groove, and the sliding plate 10 is located on both sides of the cross bar 9 with U-shaped rod 11 plug-in grooves, which are convenient for passing through the groove at the top of the cross bar 9, so that the U-shaped rod 11 can fix the position of the cross bar 9 while plugging with the sliding plate 10, the push rod 6 is located in the part of the groove at the top of the torsion bar 1 to adjust the reset spring 7, and the reset spring 7 is fitted with the bottom of the sliding plate 10, so that the reset spring 7 can be taken out after the sliding plate 10 is removed through the action of the sliding plate 10.

[0025] When the utility model is used, first check whether each device can work normally. When each device can work normally, when the whole wrench is used, the hexagonal groove inside the sleeve 2 is used to twist the torsion rod 1, and the nut on the screw rod can be removed. After the nut is removed, the sleeve 2 is used to plug the screw rod again, so that the screw rod is close to the impact plate 5, and the staff directly hits the expansion plate of the side wall of the sliding rod 14 with a leather hammer, so that the sliding rod 14 is forced to drive the sliding plate 10 to slide at the same time, and through the limit of the cross bar 9, the sliding plate 10 drives the push rod 6 to slide at the same time. , and then the impact plate 5 that is forced to slide hits the screw, and through the action of the reset spring 7, the sliding rod 14, the push rod 6 and the impact plate 5 do not need to be manually reset, which makes it convenient for the staff to continuously apply force to the expansion plate until the screw is reset. When the reset spring 7 cannot accumulate elastic potential energy, the staff twists the connecting tube 4 to directly separate the connecting tube 4 from the torsion bar 1, and through the action of the rotating plate 13, the removed U-shaped rod 11 no longer limits the cross bar 9, so that the staff can take out the cross bar 9 and the sliding plate 10 in turn, which is convenient for replacing a new reset spring 7.

[0026] The utility model is beneficial in that:

[0027] 1. The impact plate is set so that when the sliding rod slides under force, the push rod and the impact plate slide at the same time. Through the action of the reset spring, the sliding rod, the push rod and the impact plate do not need to be reset manually, so that the staff can continuously knock the expansion plate to apply force, thereby facilitating the impact plate to drive the screw to reset, and then facilitating the removal of the collision bolt;

[0028] 2. Through the setting of the rotating plate, when the connecting pipe is rotated under force, the rotating plate drives the U-shaped rod without being affected, and then when the connecting pipe and the torsion bar are separated at the same time, the U-shaped rod can be separated from the sliding plate, and then the cross bar and the sliding plate can be removed, so that it is convenient to replace a new reset spring and facilitate the normal use of the entire wrench.

[0029] The modules involved are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by this utility model does not involve improvements to software and methods.

[0030] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
