Description

Technical Field

[0001] The present invention relates to the technical field of manual tools, specifically a nut screwing tool with a locking function. Background Art

[0002] When using an ordinary tool to screw a nut, there is a certain gap between the tool and the nut, resulting in non-face-to-face contact between the tool and the nut during nut screwing. When the functional surface of the tool wears, the gap between the tool and the nut will become larger and larger, and in severe cases, the tool may fail. Summary of the Invention

[0003] The purpose of the present invention is to solve the above-mentioned technical deficiencies, eliminate the gap between the nut and the tool, and provide a nut screwing tool with a locking function that is reasonably designed, simple in structure, low in cost, easy to manufacture, and labor-saving, time-saving, and effort-saving during use.

[0004] The technical solution adopted by the present invention is a nut screwing tool with a locking function, which is characterized by including a wrench body, a movable block, a slider, a locking switch, an elastic member, rivet A, and rivet B. One end of the wrench body is provided with a U-shaped fork for screwing the nut. One side of the fork is provided with a T-shaped chute, and a long chute is provided up and down in the middle of the chute. The upper part of the movable block is provided with symmetric grooves on both sides, which can slide in the T-shaped chute at the head of the wrench body. The middle part is provided with a through hole and is fixed in the long chute at the head of the wrench body through rivet A and can slide left and right in the long chute. The elastic member is installed inside the T-shaped chute at the head of the wrench body. The other end of the wrench body is provided with a plum blossom-shaped through hole, and the nut can be placed in the through hole. The inner side is provided with a groove. One end of the slider is a plane, and the other end is provided with a V-shaped groove and can be stuck in the tip of the nut. The slider can slide left and right in the groove. The outside of the groove is provided with a through long chute, and through holes are provided on both sides of the long chute. The head of the locking switch is provided with a boss, and the middle part is provided with a through hole and is fixed in the long chute on the plum blossom side of the wrench body through rivet B.

[0005] The present invention is reasonably designed, simple in structure, low in cost, easy to manufacture, and labor-saving, time-saving, and effort-saving during use, and is a nut screwing tool with a locking function. Brief Description of the Drawings

[0013] As shown in the figure, a nut screwing tool with a locking function includes a wrench body 4, a movable block 1, a slide block 7, a locking switch 6, an elastic member 3, a rivet A 2, and a rivet B 5. One end of the wrench body 4 is provided with a U-shaped fork for screwing the nut. One side of the fork is provided with a T-shaped chute, and a long chute is provided up and down in the middle of the chute. The upper part of the movable block 1 is provided with symmetric grooves on both sides, and the grooves can slide in the T-shaped chute at the head of the wrench body 4. A through hole is provided in the middle and is fixed in the long chute at the head of the wrench body 4 through the rivet A 2 and can slide left and right in the long chute. The elastic member 3 is installed inside the T-shaped chute at the head of the wrench body 4. The other end of the wrench body 4 is provided with a plum blossom-shaped through hole, and the nut can be placed in the through hole. A groove is provided inside. One end of the slide block 7 is a plane, and the other end is provided with a V-shaped groove and can be stuck in the tip of the nut. The slide block 7 can slide left and right in the groove. A through long chute is provided outside the groove, and through holes are provided on both sides of the long chute. The head of the locking switch 6 is provided with a boss, and a through hole is provided in the middle and is fixed in the long chute on the plum blossom side of the wrench body 4 through the rivet B 5.

[0014] When using the end with the U-shaped fork, first push the movable block 1 inward, the U-shaped opening increases, then place the nut between the U-shaped openings, and release the movable block 1. The movable block 1 slides outward under the action of the elastic member 3, and the opening gradually decreases to achieve the purpose of clamping the nut.

[0015] When using the plum blossom end, first open the locking switch 6 upward. The slide block 7 is located inside the groove. Place the nut into the plum blossom-shaped through hole, press the locking switch 6 downward. The boss at the head of the locking switch 6 pushes the slide block 7 outward. When the slide block 7 slides to one side of the nut, the locking switch 6 and the slide block 7 stop moving to achieve the purpose of locking the nut.
