Description
Technical field
The present invention relates to a kind of gas power impact tool, especially a kind of nailing gun depth adjusting mechanism, belong to combustion gas
Power tool technical field.
Background technology
Nailing gun drives the hit piece action in rifle depth adjusting mechanism to complete the fastening such as nail generally using combustion gas as power
The impact of part, it is a kind of gas power instrument being widely used.In order to meet the requirement of different impact depth, nailing gun
Pipette tips position is provided with depth adjusting mechanism.The typical structure of existing nailing gun depth adjusting mechanism is as shown in figure 1, beating at pipette tips
The front end of nail seat 2 is equipped with the striking with sheath 4 first 3, and the installation push pedal 6 of its side.The rear end of striking first 3 forms with push pedal 6 and moved
It is secondary.Two support arms that the push pedal 6 is extended live what is inserted rotatable adjusting screw rod 5 and be connected by straight pin 7 and adjusting screw rod
Adjusting knob 8.The rear end screwed hole of the external part of adjusting screw rod 5 and striking arm 6 forms screw pair.When screwing adjusting knob, spiral
Adjutant drives striking head to stretch, so as to adjust nailing depth.1 in Fig. 1 is the striking arm connect with striking title, and 9 be that increase is adjusted
Save the elastic steel ball gear mechanism of button rotation feel.
This existing depth adjusting mechanism is not only complicated, and due to configuration biases, is unfavorable for force during nailing.
The content of the invention
It is an object of the invention to：The shortcomings that existing for above-mentioned prior art, propose that one kind is not only simple in structure, adjusted
Convenient, stress ideal, and the nailing gun depth adjusting mechanism of reliable operation.
In order to reach object above, nailing gun depth adjusting mechanism of the invention includes the striking that front end has straight length
Head, the straight length it is anterior it is cylindrical have screw the external screw thread of regulation ring, the rear portion of the straight length be cylindrical tube, it is described outside
The jump-ring slot for clamping and keeping spring is formed between screw thread and cylindrical tube, the jump-ring slot, which at least has at one, gets deeply stuck in region；It is described
Spring is kept to be fastened in the circumferentially positioned circular arc of jump-ring slot in both ends, it is described to keep getting deeply stuck in region described in the middle part correspondence of spring
With outer convex arc；The middle part of the regulation ring has the regulation internal thread screwed with the external screw thread, and the regulation ring is corresponding to be touched
The one end for cylindrical tube of tapping the head has expanding endoporus；The expanding endoporus is formed with least one outer convex arc phase with the holding spring
The recessed arc matched somebody with somebody.
In operation, when application external force screws regulation ring, the outer convex arc of spring can will be kept by being initially positioned at recessed pockets
What the position of the circumferentially opposed rotation of interior constraint was radially depressed into striking head jump-ring slot gets deeply stuck in region, so as to release circumferential constraint, makes tune
Section ring is able to rotate freely relative to striking head, changes the axial length that regulation ring stretches out striking head, reaches regulation setting rifle on demand
The purpose of nailing depth, when terminating nailing depth regulation, the outer convex arc of holding spring is still set to block under elastic reset effect
Enter regulation ring, accordingly even when by the impact shock of nailing, regulation ring will not also circumferentially rotate with respect to striking head, therefore be able to
The nailing depth mixed up is kept, ensures nailing gun reliably working.As can be seen here, the present invention have it is simple in construction, easy to adjust, by
Power is good, the remarkable advantage of reliable operation.
Further improve of the invention is that the outer end of the expanding endoporus is formed with locking internal thread, the locking internal thread
Regulation ring cowling is screwed, the cylindrical tube of the endoporus and the striking head of the regulation ring cowling is slidably matched.It can so be always ensured that
The axiality of regulation ring and striking head cylindrical tube, thus helps to ensure that striking head stress is good.
Of the invention further, the bottom land of the jump-ring slot is the semi arch with keeping spring diameter to match.
Further, there is the jump-ring slot present invention the relative of plane formation at two to get deeply stuck in region.
It is of the invention further, two relative get deeply stuck between region of the jump-ring slot have two relative positioning shrinkage pools.
The present invention is also further, and the both ends for keeping spring are respectively fastened in the bending head of positioning shrinkage pool.
Further, the regulation ring cowling has seam flange to the present invention.
