Description

A kind of nailing gun depth adjusting mechanism
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.

Embodiment
Embodiment one
The nailing gun depth adjusting mechanism of the present embodiment as shown in Figure 2,3, 4, the basic structure of striking first 3 and its with nailing seat Installation is essentially identical equal to prior art, and its front end has straight length, and the front portion of the straight length is as shown in Figure 5,6, cylindrical to have The external screw thread 3-1 of regulation ring 13 is screwed, the rear portion of straight length is cylindrical tube 3-2, is formed between external screw thread 3-1 and cylindrical tube 3-2 Clamp the jump-ring slot 3-3 for keeping spring 12.Jump-ring slot 3-2 bottom land is the semi arch with keeping the diameter of spring 12 to match, and With relative getting deeply stuck in region 3-4 by what milling flat horizontal surface was formed at two.Jump-ring slot 3-2 bis- is relative to be got deeply stuck between the 3-4 of region with two Relative positioning shrinkage pool 3-5.
Spring 12 is kept as shown in fig. 7, overall is in semicircular arc, both ends are fastened in positioning shrinkage pool 3-5 when being respectively and assembling Bending head 12-2, so as to jump-ring slot it is circumferentially positioned, region 3-4 is correspondingly got deeply stuck at middle part has outer convex arc 12-1.Regulation ring 13 Referring to Fig. 3,4, middle part has the regulation internal thread screwed with first 3 external screw thread of striking, one end tool of its corresponding striking head cylindrical tube There is expanding endoporus 13-2, expanding endoporus 13-2 outer end is formed with locking internal thread 13-1.As shown in figure 8, expanding endoporus is formed with two Place is with keeping the relatively recessed arc 13-2 that the outer convex arc 12-1 of spring 12 matches.Locking internal thread 13-1 is screwed with seam flange Regulation ring cowling 11, the cylindrical tube of the endoporus of the regulation ring cowling 13 and the striking head is slidably matched.
Experiment proves that the nailing gun depth adjusting mechanism structure of the present embodiment is simple and direct, light and handy, manufacture and assembly process process It is good, easy to adjust, reliable operation.
