Preferably, the screwing head comprises a sleeve connected with the screwing rod through threads and a limiting baffle fixedly arranged on the front end face of the sleeve and opposite to the screwing rod, and the linear flat head is positioned on the front end face of the limiting baffle. The screwing head of the optimized scheme is connected with the screwing rod through threads, so that a proper straight flat head can be conveniently replaced according to the specification of a screw in the using process, and the universality is improved.

Preferably, the screw placing notch is an isosceles trapezoid with a large upper part and a small lower part. This optimization scheme sets up to isosceles trapezoid through placing the opening with the screw, can adapt to the screw use of multiple diameter specification on the one hand, and another convenience is favorable to increasing the frictional force to the screw, further improves the stability that the screw was placed.

Preferably, the twisting rod is provided with a positioning table positioned between the two guide sleeves, and a spring sleeved on the twisting rod is arranged between the positioning table and the rear guide sleeve. This optimization scheme is through setting up the spring, and when twisting and move just beginning, utilize the elasticity top tight screw of spring, improve the convenience of operation, and the spring compression back can adapt to the screw use of multiple length specification.

As optimization, a through hole which is located below the guide sleeve and penetrates through the thickness direction of the bottom plate is formed in the bottom plate, and the upper portion of the side wall of the through hole is welded with the bottom of the guide sleeve. This optimization scheme is through setting up the through-hole, conveniently follows bottom plate bottom surface welding uide bushing to be favorable to increasing welding area, improved the welded fastness.

The utility model has the advantages that: the flat head of a style of calligraphy provides the support to the screw front end, places the opening through the screw and provides support and horizontal restriction for the screw portion of screw, has avoided the screw to drop, simple structure moreover, and the cost of manufacture is low, and the processing degree of difficulty is little, very is fit for using in the building decoration construction.

Detailed Description

In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.

As shown in fig. 1, the self-tapping screw drilling device for building decoration construction comprises a bottom plate 9, two guide sleeves 3 fixedly connected to the bottom plate, and a screwing rod 2 sequentially penetrating through inner holes of the two guide sleeves, wherein the diameter of the inner hole of each guide sleeve 3 is matched with that of the screwing rod, and the screwing rod can slide in the guide sleeves in a reciprocating manner. The rear end of the twisting rod is fixedly connected with a holding handle 1, the holding handle 1 is coated with a rubber layer, and anti-skid particles are arranged on the surface of the rubber layer so as to reduce the damage to the palm of an operator.

The front end of the twisting rod 2 is detachably and fixedly provided with a twisting head, and the front end of the twisting head is provided with a linear flat head 8. Specifically, the twisting head comprises a sleeve 5 connected with the twisting rod through threads and a limiting baffle which is fixedly arranged on the front end face of the sleeve and opposite to the twisting rod, the linear flat head 8 is positioned on the front end face of the limiting baffle, an internal thread is arranged on the inner wall of the sleeve, an external thread matched with the thread on the inner wall of the sleeve is arranged at the front end of the twisting rod, and when the screw 6 is twisted, the threads between the sleeve and the twisting rod are in a screwing state. Carry out the axial spacingly to twisting the pole through limit baffle to guarantee the reliability of twisting the screw.
