Be equipped with square groove mouth and cross -shaped groove mouth with the axle center on fastening screw's the screw cap, can use cylindricality spanner, a style of calligraphy screwdriver or philips screwdriver cooperation to tighten or dismantle the stand wear and tear rate height of screw, especially square groove mouth, effectively avoid cross -shaped groove mouth wearing and tearing back, can't tighten the dismantlement screw with a style of calligraphy screwdriver or cross flute profile screwdriver, lengthened the life of screw.
Description
Technical field
This utility model relates to a kind of peg, particularly relates to a kind of many instruments trip bolt.
Background technology
At present, the domestic screw commonly used is standard component, is word screw or a plus screw.This screw tightness is good, easy accessibility.But due to coordinate with screwdriver the flat recess tightened or cross recess the most simple be molded on the end face of screw head, one word screw or plus screw are after repeatedly dismounting, often it is worn at flat recess or cross recess cell wall, insert flat recess or cross recessed screwdriver head is somewhat exerted oneself, i.e. skid off in groove, cannot realize tightening and dismantling of screw, the service life causing screw is the longest.
Utility model content
The deficiency that this utility model exists for prior art just, it is provided that a kind of many instruments trip bolt.
For solving the problems referred to above, technical solution adopted in the utility model is as follows:
A kind of many instruments trip bolt, including screw cap and rivet nut, described 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 with square notch center superposition, and one end of rectangular notch be vertically connected on square each limit of notch center, the other end be positioned at square notch outside.
Further, the degree of depth of the depth ratio square notch of described cross notch is high.
Further, described cross notch is provided with wearing layer with the inwall of square notch.
Compared with prior art, implementation result of the present utility model is as follows for this utility model:
One many instruments trip bolt described in the utility model, the screw cap of trip bolt is provided with square notch and the cross notch of concentric, cylindricality spanner, slotted point screwdriver or Philips screwdriver can be used to coordinate tighten or knockout screw, the especially wear-resistant rate of square notch is high, after being prevented effectively from the abrasion of cross notch, knockout screw cannot be tightened with slotted point screwdriver or cross flute profile screwdriver, extend the service life of screw.
Accompanying drawing explanation
Fig. 1 is one many instruments trip bolt structural representation described in the utility model；
Fig. 2 is that the A of Fig. 1 is to schematic diagram.
Detailed description of the invention
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Figure 1 with shown in Fig. 2, described one many instruments trip bolt includes screw cap 1 and rivet nut 2, described 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 with square notch 3 center superposition, and one end of rectangular notch be vertically connected on square each limit of notch 3 center, the other end be positioned at square notch 3 outside.
The screw cap 1 of trip bolt is provided with square notch 3 and the cross notch 4 of concentric, cylindricality spanner, slotted point screwdriver or Philips screwdriver can be used to coordinate tighten or knockout screw, the especially wear-resistant rate of square notch 3 is high, after being prevented effectively from cross notch 4 abrasion, knockout screw cannot be tightened with slotted point screwdriver or cross flute profile screwdriver, extend the service life of screw.
The degree of depth of the depth ratio square notch 3 of described cross notch 4 is high, it is simple to slotted point screwdriver or Philips screwdriver are adequately inserted in cross notch 4, improves the revolving force tightening or dismantling screw.
Described cross notch 4 is provided with wearing layer 5 with the inwall of square notch 3, effectively increases the wear strength of cross notch 4 and square notch 3, extends the service life of screw further.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
