Description
Technical field
The present invention relates to a kind of peg, more particularly to a kind of many instrument trip bolts.
Background technology
At present, the domestic screw generally used is standard component, as minus screw or plus screw.This screw tightness is good, convenient disassembly.But it is due to that the flat recess or cross recess tightened with screwdriver cooperation are molded on the end face of screw head only simplely, minus screw or plus screw are after repeatedly dismounting, often it is worn at flat recess or cross recess cell wall, the screwdriver head of insertion flat recess or cross recess is somewhat exerted oneself, skidded off out of groove, tightening and dismantling for screw can not be realized, causes the service life of screw not long.
The content of the invention
The present invention is exactly in view of the deficienciess of the prior art, there is provided a kind of many instrument trip bolts.
To solve the above problems, the technical solution used in the present invention is as follows：
A kind of many instrument trip bolts, including screw cap and rivet nut, the screw cap is provided with square notch and cross notch, the center of square notch and the center superposition of screw cap, cross notch includes four rectangular notches, the center of cross notch and the center superposition of square notch, and one end of rectangular notch is vertically connected on the center on each side of square notch, the other end is located at the outside of square notch.
Further, the depth of the square notch of the depth ratio of the cross notch is high.
Further, the inwall of the cross notch and square notch is provided with wearing layer.
Compared with prior art, implementation result of the invention is as follows by the present invention：
A kind of many instrument trip bolts of the present invention, the screw cap of trip bolt is provided with concentric square notch and cross notch, it cylindricality spanner, slotted point screwdriver or Philips screwdriver can be used to coordinate to tighten or knockout screw, the wear-resistant rate of especially square notch is high, it is prevented effectively from after the abrasion of cross notch, knockout screw can not be tightened with slotted point screwdriver or cross flute profile screwdriver, extend the service life of screw.
Brief description of the drawings
Fig. 1 is a kind of many instrument trip bolt structural representations of the present invention；
Fig. 2 for Fig. 1 A to schematic diagram.
Embodiment
Illustrate present disclosure below in conjunction with specific embodiments.
As shown in Figure 1 and shown in Fig. 2, a kind of described many instrument trip bolts include screw cap 1 and rivet nut 2, the screw cap 1 is provided with square notch 3 and cross notch 4, the center of square notch 3 and the center superposition of screw cap 1, cross notch 4 includes four rectangular notches, the center of cross notch 4 and the center superposition of square notch 3, and one end of rectangular notch is vertically connected on the center on each side of square notch 3, the other end is located at the outside of square notch 3.
The screw cap 1 of trip bolt is provided with concentric square notch 3 and cross notch 4, it cylindricality spanner, slotted point screwdriver or Philips screwdriver can be used to coordinate to tighten or knockout screw, the wear-resistant rate of especially square notch 3 is high, it is prevented effectively from after the abrasion of cross notch 4, knockout screw can not be tightened with slotted point screwdriver or cross flute profile screwdriver, extend the service life of screw.
The depth of the square notch 3 of the depth ratio of the cross notch 4 is high, is easy to slotted point screwdriver or Philips screwdriver to be adequately inserted in cross notch 4, improves the revolving force for tightening or dismantling screw.
The inwall of the cross notch 4 and square notch 3 is provided with wearing layer 5, effectively increases the wear strength of cross notch 4 and square notch 3, further extends the service life of screw.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, any modifications, equivalent substitutions and improvements made within the spirit and principles of the invention etc., should be included in the scope of the protection.
