Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses a screw. Referring to fig. 1 and 2, the screw cap includes a screw cap 1 and a screw rod 2 integrally formed with the screw cap 1. One side of the screw cap 1 facing the screw rod 2 is integrally formed with a circular support cushion plate 8, and the diameter of the support cushion plate 8 is larger than that of the screw cap 1. After the screw is screwed, the supporting base plate 8 can increase the contact area between the screw cap 1 and the object, and reduce the pressure of the screw cap 1 on the surface of the object, so that the screw cap 1 is prevented from damaging the surface of the object. A plurality of supporting blocks 9 are fixedly connected between the supporting base plate 8 and the outer side wall of the screw cap 1 at intervals along the circumferential direction. The support blocks 9 can give a supporting force to the support mat 8, thereby preventing the support mat 8 from being deformed accidentally.

Referring to fig. 2 and 3, two rotating grooves 11 are symmetrically formed in one side, away from the screw rod 2, of the nut 1 along the axis, a rotating plate 3 which slides up and down is arranged in each rotating groove 11, a connecting shaft 4 is connected between two opposite inner side walls of each rotating groove 11 in a sliding mode, and the connecting shaft 4 can only slide in the rotating grooves 11 and cannot be separated from the rotating grooves 11. The connecting shaft 4 is arranged at one end of the rotating plate 3 close to the bottom wall of the rotating groove 11 in a penetrating way, so that the rotating plate 3 can slide up and down in the rotating groove 11. When the screw needs to be turned, the two turning plates 3 are pulled out from the turning grooves 11 by hand and then inclined in directions away from each other, so that the nut 1 can be unscrewed by means of the turning plates 3.

Referring to fig. 2, a rectangular fixing plate 5 for closing the rotation groove 11 is fixedly connected to an upper end of the rotation plate 3, and the fixing plate 5 is perpendicular to the rotation plate 3. The fixed slot 12 that supplies fixed plate 5 card to go into is seted up to one side that nut 1 deviates from screw rod 2, and fixed slot 12 communicates with rotation groove 11, and one side fixedly connected with connecting block 52 that fixed plate 5 deviates from rotor plate 3. The fixed plate 5 can reduce the entry of dust into the rotation groove 11. The fixing plate 5 can be pulled out from the fixing groove 12 after the connecting block 52 is held by hands, so that time and labor are saved.

Referring to fig. 2 and 4, a fastening pad 51 made of a silicone material is fixedly connected to an edge of the fixing plate 5 along a circumferential direction, and a fastening groove 13 into which the fastening pad 51 is inserted is formed in an inner side wall of the fixing groove 12 along the circumferential direction. After the fixed plate 5 is pushed into the fixing groove 12, the fastening pad 51 of the fixed plate 5 is caught in the fastening groove 13, thereby restricting the pivoting plate 3 from being unintentionally separated from the pivoting groove 11.

Referring to fig. 3 and 4, the outer side walls of the two rotating plates 3 which deviate from each other are hinged to support arms 31, the two ends of the bottom wall of the fixing groove 12 are provided with support grooves 14 for clamping the movable ends of the support arms 31, and the edges of the movable ends of the support arms 31 are provided with chamfers 311. Pull out two rotor plates 3 from rotating the inslot 11 earlier, incline 45 degrees with two rotor plates 3 towards the direction of keeping away from each other again for in the expansion end of support arm 31 inserted the brace groove 14, support arm 31 can give rotor plate 3 a holding power, thereby make two rotor plates 3 all keep the tilt state, people support two rotor plates 3 with the thumb and the forefinger of same hand respectively, can rotate the screw, labour saving and time saving.

Referring to fig. 3 and 4, the movable end of the support arm 31 is fixedly connected with a first magnet 6, and the bottom wall of the support groove 14 is fixedly connected with a second magnet 7 which is attracted to the first magnet 6. After the supporting arm 31 is inserted into the supporting slot 14, the first magnet 6 on the supporting arm 31 and the second magnet 7 on the bottom wall of the supporting slot 14 attract each other, thereby improving the connection stability of the supporting arm 31 in the supporting slot 14.

The implementation principle of a screw of this application embodiment does: when the screw needs to be rotated, firstly, two connecting blocks 52 are respectively pinched by two hands to pull out two rotating plates 3 from the rotating groove 11, and then the two rotating plates 3 are inclined by 45 degrees towards the directions away from each other, so that the movable end of the supporting arm 31 is inserted into the supporting groove 14, and therefore the two rotating plates 3 are all kept in an inclined state, the thumb and the forefinger of the same hand are respectively abutted against the two rotating plates 3, the screw can be rotated, and the screw is time-saving and labor-saving.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
