Abstract
The utility model discloses a sleeve used for assembling a binding screw, which is characterized in that the sleeve includes a stem casing; a cover cylinder is arranged at the front end of the stem casing; and a ring-shaped contraction mouth is formed at the front end of the cover cylinder. When the sleeve is used for assembling the binding screw, the cap part of the screw is clamped in the ring-shaped contraction mouth, so that the screw is prevent from falling off; due to the protective effect of the cover cylinder, injuries to fingers of a builder caused by the screw can be avoided; and the utility model is far more efficient and safer.
Description
Technical field
The utility model belongs to a kind of hardware ﹠ tools, specifically is a kind of assembling trip bolt sleeve.
Background technology
Have now in the building decoration construction, need a large amount of assembling trip bolts.Assembling is during trip bolt, normally hold screw with the magnet of screwdriver end after, to assembling the position tapping.Rigging screw position in some occasion, its density is very high, and when the assembling position screwed screw, screw was difficult to shoot with screwdriver, obscission takes place, overexert, also can stab workmen finger, some is in order to shoot a screw five or six screws that may come off, very waste time and energy, influence man-hour, efficient is very low, has increased construction cost.
The utility model content
The purpose of this utility model provides a kind of assembling trip bolt sleeve, during the assembling trip bolt, uses this instrument, the toner screw phenomenon can not take place, and the situation that screw injures workmen's finger can not take place yet, and efficient improves a lot, and is also very safe.
Technical solutions of the utility model are as follows:
A kind of assembling trip bolt sleeve is characterized in that including the bar cover, and bar cover front end has a cover tube, and described cover tube front end has an annular contraction mouth.
Described trip bolt sleeve is characterized in that described annular contraction mouth inboard is cambered surface.
Described trip bolt sleeve is characterized in that having on the described cover drum outer wall straight trough of disconnection.
Described trip bolt sleeve is characterized in that described bar cover and cover tube material are plastics.
During use, at first the bar cover is set on the screw rod of screwdriver, now screw is filled in the annular contraction mouth of cover tube front end, the internal diameter of annular contraction mouth is slightly less than the screw cap diameter, and annular contraction mouth has certain elasticity simultaneously, after screw enters annular contraction mouth, its cap portion is stuck in the annular contraction mouth, can not come off, will cover tube and cover on department of assembly's site surface, screw is aimed at the assembling point, rotate screwdriver by hand, at this moment the cover tube can not rotate, and screw is constantly shot the assembling point, even first screw is difficult to shoot the assembling point, but screw cap portion is positioned at annular contraction mouth, can not come off, can carry out the assembling second time again, improve the efficient of cartridge screw greatly; Because workmen's finger has been protected in the effect of cover tube, and is safe.
