Description

Reinforcing bar guard cutter

The utility model relates to a kind of reinforcing bar guard cutter, is applied to the specific purpose tool of fire-fighting, patrol police or other aspects cutting reinforcing bar guard.

Now a lot of units and family are for antitheft, the reinforcing bar guard generally has been installed on door window, and, this reinforcing bar guard is not only installed on one-storey house and first floor, also on the high building of multilayer, install, though this is beneficial to safety, strengthened safety, antitheft, but handle accident for the fire-fighting fire extinguishing and the police and caused difficulty, at present, fire-fighting or other police treat this situation and have to use iron shears to cut off reinforcing bar, yet use iron shears in the high-altitude sometimes, and are very inconvenient, also dangerous, use iron shears to be difficult to cut off when running into, had a strong impact on fire attack and, still do not had other forms of reinforcing bar guard cutting tool at present the processing of burst case than bar reinforcement.

The purpose of this utility model provides a kind of specific purpose tool that utilizes gunpowder explosion to try hard to recommend moving piston cutting reinforcing bar guard.

The utility model is achieved in that

Reinforcing bar guard cutter, cutter 1, front rest 2, outer sleeve body 3, bonnet 4, back cutter 5, piston rod 6, cartridge chamber body 7, striker post 8, firing pin 9, striker spring 10, plate machine 11, handle body 12 before comprising; Preceding cutter 1 and front rest 2 are one, and front rest 2 is connected with outer sleeve body 3 by screw-button 13, and fixing by alignment pin 14; Back cutter 5 and piston rod 6 are one, and piston rod 6 front bottom end cut one section plane groove, and the front end side is drilled with a screwed hole, and piston rod return handle 15 is installed; Cartridge chamber body 7 is cylinders of boring in the middle of one; The front end face of striker post 8 has the bullet draw-in groove, and the handle of push-and-pull striker post 8 is arranged at top, and the bottom has segment length's strip groove; Firing pin 9 rear ends are hollow tubulars, and striker spring 10 is contained in the hollow pipe; Outer sleeve body 3 front ends have screw-button 13, alignment pin 14, alignment pin 14 is made up of spring and slide block, leave plane boss slide rail on the front inner wall of outer sleeve body 3, be complementary with the plane groove of piston rod 6, guarantee that back cutter blade is parallel with preceding cutter, the front portion also has the strip hole 16 that piston rod return handle 15 moves forward and backward, there is the jump ring 17 of return handle 15 rear end in hole, jump ring 17 is made up of spring and ball, outer sleeve body 3 begins internal diameter and becomes big after the position that cartridge chamber body 7 is installed, and the upside before the position that cartridge chamber body 7 is installed has the strip relief hole, the rear section of outer sleeve body 3 has the sickleshaped hole 18 that striker post 8 handles move forward and backward and rotate, and reaches the rearmost end of outer sleeve body 3 always; Bonnet 4 is inside spins; Handle body 12 is connected with outer sleeve body 3 usefulness screws.

Benefit of the present utility model is:

Small volume and less weight is carried easy to operately, and cutting rapidly.

Describe the utility model in detail below in conjunction with accompanying drawing.
