Description

Pneumatic peg rifle

Technical field

The utility model relates to a kind of pneumatic tool, particularly a kind of pneumatic peg rifle.

Background technology

At present, the working procedure that installs and fixes peg is: use electric impact drill to punch on the wall, then bolt is inserted, screw is thrown into or screwin again; Shi Gong shortcoming is like this: the workman need be after warming plate and body of wall tentatively stick with glue, use heavy electric impact drill to get a hole inwards from the warming plate outside, throw body of wall into, again plastics bolt cover is inserted along this hole, then screw is injected the bolt cover in this hole, use screwdriver (perhaps electric screw driver) or hammer that nail is hit or screwin again, so just finished the operation of installing.This shortcoming is very obvious, use 2 instruments, and for example electric impact drill and screwdriver just can be finished the fixing of a peg, and the time is also very long, and labour intensity is also bigger.

The utility model content

The purpose of this utility model is that a kind of pneumatic peg rifle will be provided, solve on body of wall, can not to one-time fix warming plate at present, during construction labor strength big problem.

The purpose of this utility model is achieved in that this peg rifle comprises: trigger, contact plate, switch valve, cylinder head, the body of a gun, main piston, nail hitting bar, buffer, ring flange, stage clip, block, guide rod, bolt, nail, arm controller, safety arm, bolt and resilient key; End in the rifle external body has cylinder head to be connected on the rifle body, and Control Component and safety arm assembly are connected a side of rifle body, and described Control Component has switch valve, trigger and contact plate, and contact plate is connected on the trigger, switch valve and contact plate overlap joint; Described safety arm assembly has arm controller and safety arm, and arm controller is connected on the rifle body, and safety arm is connected on the arm controller, safety arm and contact plate overlap joint; Be connected with ring flange, stage clip, block and the guide rod of rifle head assembly in the bottom of rifle body, wherein, stretch out in the hole that guide rod passes in the middle of the ring flange, and stage clip is connected on the guide rod by block and resilient key; And the ring flange of whole rifle head assembly is connected on the rifle body by bolt; In rifle body inside, connecting the nail hitting bar on the main piston, the main piston below is connected with buffer.

Beneficial effect: owing to adopted such scheme, after peg is made up and has been enclosed within the guide rod outside, aligning is connected the warming plate on the body of wall, after depressing, guide rod has a strength that makes progress to promote connection safety arm in the above, by being connected the arm controller guiding above the rifle body, aim at the contact plate of trigger assembly, open switch valve, power impacts fast by main piston and nail hitting bar and moves down, and the nail in the peg is impacted enter warming plate and body of wall; Bolt is enclosed within on the rifle head, directly just can be inserted into to squeeze into till being scheduled to and gets final product.Need not hole and plug plug pin and directly one-time fixing with body of wall easy construction and light.Installation rate is higher than tradition more than 5 times; Save nearly 5 times of labour, integrated cost reduces about 4 times.Reached the purpose of this utility model.

Advantage: can will be enclosed within the peg combination above the guide rod and squeeze in warming plate and the body of wall once, reduced specially at body of wall and used electric impact drill to punch separately, inserted bolt and nail again, and then twisted or the complexity of tack hole and heavy program, easily quick, the while remarkable in economical benefits.
