[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0025] This embodiment is a cross self-tapping screw with a guide.
[0026] like Figure 1-4 As shown, it includes a nail body 1 and a nail cap 2. A cross reinforcing protrusion 3 is provided in the middle of the outer surface of the upper end of the nail body 1, a cross limiting groove 7 is provided in the middle of the outer surface of the lower end of the nail cap 2, a cross hole groove 5 is provided in the middle of the outer surface of the upper end of the nail cap 2, and an expansion cross groove 6 is provided on the upper part of the cross hole groove 5.
[0027] The upper outer surface of the nail body 1 is connected to the middle of the lower outer surface of the nail cap 2; a reinforcing block 4 is fixedly installed on the outer wall of the upper part of the nail body 1, and the upper outer surface of the reinforcing block 4 and the lower outer surface of the nail cap 2 are welded; the outer wall of the cross reinforcing protrusion 3 is plugged into the cross limiting groove 7; after the reinforcing block 4 and the nail cap 2 are welded, the cross reinforcing protrusion 3 is inserted into the cross limiting groove 7.
[0028] It should be noted that the utility model is a cross self-tapping screw with a guide, which is provided with a nail body 1 and a nail cap 2. When connecting the nail body 1 and the nail cap 2, the cross reinforcement protrusion 3 is inserted into the cross limiting groove 7, and then the reinforcement block 4 is connected to the bottom of the nail cap 2 to increase the strength of the connection between the nail body 1 and the nail cap 2; an expanded cross groove 6 is provided at the upper end of the cross hole groove 5, which is convenient for inserting one end of the cross screwdriver into the cross hole groove 5. The expanded cross groove 6 plays a guiding role, reducing the difficulty of inserting the cross screwdriver into the cross hole groove 5, and facilitating operation.
