Description of the Invention: [Technical Field] The present invention relates to a lock screw device, and more particularly to an automatic lock screw arrangement for automatically locking a screw and ensuring the positioning of a screw. [Prior Art] [0002] The connection between products is usually glued, riveted, pinned, and screwed. The most commonly used is a threaded connection. When manually locking the screw, it is required. A hand-held screw is attached to the pre-locking position of the workpiece. The other hand holds the 0 and presses the force while pressing the screwdriver until the lock is tight. As the screw gradually penetrates into the workpiece, the screwdriver is given. The torque needs to be constantly increased. Therefore, manual execution of the locking screw is quite time-consuming and labor-intensive and it is not easy to control the tightness of each screw evenly, especially for manual operation on the production line. [0003] In order to improve the working efficiency of the locking screw, the operator developed an automatic locking screw device. For example, an automatic locking screw device is controlled by the pressing of the micro switch to make the air pressure. / The air inlet enters the body and pushes the activity to turn forward. At the same time, the screwdriver is turned to achieve the purpose of automatically locking the screw, and when the micro switch is released. The solenoid valve immediately switches the intake hole to the exhaust hole to make the gas in the cylinder be discharged from the intake pipe. At this time, the movable shaft is returned to the original position by the elastic force. However, one of the modes is to be locked to a workpiece. The screw (especially the small screw) is easy to offset the position of the workpiece when aligning the workpiece', so that the positioning of the screw is not allowed. SUMMARY OF THE INVENTION [0004] In view of the above, it is necessary to provide an automatic locking screw device that can automatically lock a screw and ensure that the screw is accurately positioned. 098125446 Form No. Α0Ι0Ι Page 3 of 18 0982043528-0 201103710 [0005] An automatic locking screw device for locking a screw, comprising a first sleeve, a first fixed to the first sleeve a sleeve, a positioning member of the second sleeve, and a set of elastic members disposed on the positioning member, wherein a first inclined surface of the first angle is formed on the inner side of the second sleeve a second inclined surface of the second angle, the positioning member is configured to receive the screw, and is provided with a buckle portion slidable on the first inclined surface and the second inclined surface, wherein the positioning member is detachable from the buckle When the portion slides from the first inclined surface to the second inclined surface, the elastic member is elastically deformed and opened at an angle to slide the screw out of the positioning member.

When the sliding portion is slid to the positioning portion, the nut 41 of the screw 40 is blocked by the positioning inclined surface 571 of the positioning portion 57, and the stud 43 extends into the positioning groove 573 of the three positioning members 5 The positioning hole 59 is formed. The external force forces the driver 1G to move in a first direction close to the screw 40, and the locking portion of the driver 1" is fastened to the nut 41 of the screw 40. When the groove is in the groove, the external force further drives the driver 10 to move in the first direction, so that the positioning bevel 571 of the nut (4) slides and presses the positioning slope 571 while pushing the positioning member 5G is moved in the first direction, and the elastic member 6 is thus elastically deformed by being pressed by the fastening portion 51. The three positioning members 50 are gradually opened due to being squeezed by the screw. When the locking portion 53 of the positioning member 5D is slid by the first inclined surface 731 having an angle of 76 degrees and is buckled to the second inclined surface 733 of the 74 degree angle, the 〇 positioning member 5 可使 can be The positioning portion 57 can be opened at an angle of 2 degrees, and the angle of 2 degrees of opening can cause the (four) 41 of the screw 40 to just slide off the positioning inclined surface 571 of the positioning portion 57 onto the workpiece (not shown) to be locked. [0031] The automatic locking screw device of the present invention can design different positioning members 50 according to the actual size of the screw 40, and can also change the first inclined surface 731 according to the actual size of the screw Ο diameter of the screw 4〇. The difference in the angle of the second inclined surface 733 such that the angle at which the positioning member 5 is opened is engaged with the nut 41 such that the screw is positively positioned on the workpiece to be side in another embodiment, The first set of cans 3 and the second 098125446 Form No. A0101 Page 9 of 18 pages 0982043528-0 201103710 The sleeve 70 can be formed in one. [0032] In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art of the present invention should be included in the following claims.
