To reach above-mentioned purpose, what the utility model was realized in:A kind of setscrew, including expansion oplate, activity branch
Frame lead screw and fixed head part, the travel(l)ing rest lead screw include U cradle portions and threaded shank, in the U cradle portions formed with
First U-lag;The fixed head part includes push rod portion and fixed support portion, and the fixed support portion forms the second U-lag;
The U-lag of fixed head part second is enclosed on first U-lag through the first U-lag of travel(l)ing rest lead screw
So that the screw parts, in the second U-lag, the push rod portion is located in first U-lag;
The expansion oplate is arranged on the upper end of first U-lag;Flat pad, planar pad are cased with below the threaded shank
Nut is installed below piece;
During tightening nut, the threaded shank drives U cradle portions and expansion oplate to be integrally pulled outwardly, the relative push rod portion
Pushed up to the expansion oplate direction, when expansion oplate is encountered in the push rod portion, the expansion oplate is slowly supportted by the push rod portion
Open.
Preferably, the U cradle portions of the upper end of the travel(l)ing rest lead screw and the threaded shank of lower end are formed in one.
Preferably, the push rod portion of the fixed head part and fixed support portion are formed in one.
Preferably, the expansion oplate is connected by lock pin with U cradle portions.
Preferably, the expansion oplate is the tapering rhombic plate in a pair of two, and two rhombic plates are parallel overlapping when closing up, during opening
The expansion oplate is slowly transitioned into " one " word shape by X-shaped shape.
Preferably, the expansion oplate is provided at both ends with barb.
Preferably, flexible meson is set between the flat pad and nut.
The beneficial effects of the utility model:During the utility model tightening nut, the threaded shank drives U cradle portions and swollen
Swollen plate is integrally pulled outwardly, and the relative push rod portion is pushed up to the expansion oplate direction, when expansion oplate is encountered in the push rod portion
When, the expansion oplate is slowly strutted by the push rod portion, so when load is heavier, can haul lead screw and pull outward, relatively,
The push rod portion is then pushed up inwards, and expansion oplate can only be supportted increasing, difficult for drop-off so as to more and more firm, while this reality
It is extensive with new application, it is not only used in hardware materials for wall and is also highly suitable for use in hollow brick, porous brick, the pine such as honeycomb brick
In scattered matrix or wall.

Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
As shown in figs. 1-7, a kind of setscrew, including expansion oplate 1, travel(l)ing rest lead screw 2 and fixed head part 3, it is described
Travel(l)ing rest lead screw 2 includes U cradle portions 21 and threaded shank 22, and the threaded shank 22 of U cradle portions 21 and lower end is formed in one, this
In be integrally formed using punching press or injection one-shot forming, reduce production cost.Formed with the first U in the U cradle portions 21
Shape groove 23;The fixed head part 3 includes push rod portion 31 and fixed support portion 32, and push rod portion 31 and fixed support portion 32 are integrated into
Type, push rod portion 31 and fixed support portion 32 are integrally formed also using punching press or injection one-shot forming, again reduce production
Cost.The fixed support portion 32 forms the second U-lag 33;Second U-lag of fixed head part 33 passes through travel(l)ing rest screw
First U-lag 23 of bar, which is enclosed on first U-lag 23, causes the screw parts in the second U-lag 33, the push rod
Portion is located in first U-lag 23;
The expansion oplate 1 is arranged on the upper end of first U-lag 23, and the expansion oplate 1 passes through lock pin 6 and U cradle portions
11 connections, when the expansion oplate 1 closes up, the part dew of expansion oplate 1 is exposed at first U-lag beyond first U-lag 23
Outside 23, specifically, 1/3rd of the length of expansion oplate 1 is located at outside the first U-lag 23.
The lower section of threaded shank 22 is cased with flat pad 4, and the lower section of flat pad 4 is provided with nut 5.During tightening nut 5,
The threaded shank 22 drives U cradle portions 11 and expansion oplate 1 is overall is pulled outwardly, and relatively, the push rod portion 31 is to the expansion
The direction of plate 1 is pushed up, and when the push rod 31 encounters expansion oplate 1, the expansion oplate 1 is slowly strutted by the push rod portion 31.
The expansion oplate 1 is the tapering rhombic plate in a pair of two, and two rhombic plates are parallel overlapping when closing up, described swollen during opening
Swollen plate 1 is slowly transitioned into " one " word shape by X-shaped shape, and the utility model is applied loose in hollow brick, porous brick, honeycomb brick etc.
Matrix or materials for wall when, " one " word shape can be supportted.
The more king bolt that the expansion oplate 1 supports just is fixed more firm, and the expansion oplate 1 is provided at both ends with barb 7, institute
