Technical scheme

For the purpose of switching between realizing above-mentioned T style of calligraphy screw and the normal screw, the utility model provides a following technical scheme: t style of calligraphy screw, including horizontal head, hexagonal groove has been seted up to horizontal head's bottom, hexagonal groove's inside is pegged graft and is had outer hexagon head, outer hexagon head's bottom fixed mounting has the screw body, the through-hole has all been seted up to horizontal head's both sides, the inside of through-hole is provided with the spring, the one end of spring is provided with the push pedal, one side of push pedal is provided with the card pearl, the draw-in groove corresponding with the card pearl has all been seted up to outer hexagon head's both sides, the outer opening threaded connection of through-hole has the block cap.

Preferably, the bottom of the outer hexagon head extends to the lower part of the transverse head.

Preferably, half of the card bead extends to the inside of the card slot.

Preferably, one side of the push plate is provided with an installation groove corresponding to the clamping bead, so that the moving range of the clamping bead is limited, and the clamping bead cannot move randomly.

Preferably, the outer hexagonal head is mutually clamped with the transverse head through a through hole, a push plate, a clamping bead, a clamping groove, a spring and a sealing cap.

Preferably, the spring is in a compressed state, so that the clamping bead is always in a pushing state.

Preferably, the caliber of the inner opening of the through hole is smaller than the diameter of the clamping bead, so that the clamping bead can be prevented from being separated from the inside of the through hole.

Advantageous effects

Compared with the prior art, the utility model provides a T style of calligraphy screw possesses following beneficial effect:

1. this T style of calligraphy screw, when overhead through the hexagonal cover outside with violently the head, at this moment the screw body then will become T style of calligraphy screw with violently the head, when taking off through the hexagonal head outside with violently the head, at this moment the screw body will form a normal bolt with the hexagonal head outside at self top to realized the purpose of switching between T style of calligraphy screw and the normal screw.

2. This T style of calligraphy screw when switching, extrudees the push pedal through the spring, and the push pedal pushes away the card pearl, and the card pearl agrees with in the draw-in groove, utilizes agreeing with of card pearl and draw-in groove, realizes the change and the installation of horizontal head and outer hexagon head, has also reduced horizontal head and outer hexagon head alternate segregation.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a sectional view of the horizontal head of the present invention;

fig. 3 is an enlarged view of a structure at a in fig. 2 according to the present invention.

In the figure: 1-transverse head, 2-external hexagonal head, 3-screw body, 4-hexagonal groove, 5-through hole, 6-push plate, 7-clamping bead, 8-clamping groove, 9-spring and 10-sealing cap.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a T-shaped screw includes a horizontal head 1, a hexagonal groove 4 is formed at the bottom of the horizontal head 1, an outer hexagonal head 2 is inserted into the hexagonal groove 4, the bottom of the outer hexagonal head 2 extends to the lower side of the horizontal head 1, a screw body 3 is fixedly mounted at the bottom of the outer hexagonal head 2, through holes 5 are formed at both sides of the horizontal head 1, the diameter of an inner opening of each through hole 5 is smaller than the diameter of a corresponding clamping bead 7, so that the clamping bead 7 is prevented from being separated from the inside of the through hole 5, a spring 9 is arranged inside the through hole 5, the spring 9 is in a compressed state, so that the clamping bead 7 is always in a pushing state, a push plate 6 is arranged at one end of the spring 9, a mounting groove corresponding to the clamping bead 7 is formed at one side of the push plate 6, the moving range of the clamping bead 7 is limited, it is ensured that the clamping bead 7 cannot be disturbed, a clamping bead 7 is arranged at one side of the push plate 6, half of card pearl 7 extends to the inside of draw-in groove 8, and the outer opening threaded connection of through-hole 5 has a closed cap 10, and outer hexagon head 2 passes through-hole 5, push pedal 6, card pearl 7, draw-in groove 8, spring 9 and closed cap 10 and the mutual joint of horizontal head 1, has also realized the change and the installation of horizontal head 1 with outer hexagon head 2.
