Abstract

The utility model relates to a manual pulling hitter comprising an up arm lower-arm, arm-shaft and pulling rivet structure. The defect of the existing pulling hitter is that the joining-part between the up and lower arms and the joining-part between the pulling-tube casing of the pulling rivet structure and the up-arm are easy to be damaged. The other defect is that the rear ends of the up and lower arms get fastened by the U-type ouch, which is inconvenient as the ouch must be pulled down by the hands when in use. The utility model adopts the up-arm reinforce casing and lower-arm reinforce casing on the arm-shaft and also adopts the up-arm reinforce casing on the pulling-tube casing shaft. Then the touching face of the two parts become bigger and the up and lower arms and the shaft are not easy to be damaged. In addition, a locking structure is set on the back of the up-arm. The locking structure includes a U-type push-button set in the concave-hole of the back of the up-arm, a L-type frame set on the lower-arm which can hang to the U-part of the push-button and a pulling spring on the push-button. When the U-part of the push-button hangs together with the L-type frame, the up arm and the lower part are locked. And when the up-arm is pressed down, the spring pulls the U-part from the L-type frame and the up arm and lower arm stretch. The utility model can be operated by one hand.

Description

A kind of manual pulling rivet rifle

Technical field

The utility model relates to a kind of hand-operated tools, the manual pulling rivet rifle that uses in specifically a kind of building decoration.

Background technology

The manual pulling rivet rifle of existing singlehanded formula, limited because of upper arm and underarm connecting portion wall thickness, during the operation of pulling rivet rifle, last underarm opening and closing are frequent especially again, and two arms are the easiest the breaking in arm axle place.The also the easiest damage of breaking in connecting axle place of the trombone slide cover connecting portion of upper arm and blind rivet mechanism.The damage of upper arm or underarm makes wholely can not be used the pulling rivet rifle and scrap.This fatal defective directly influences the service life of pulling rivet rifle.In addition, upper arm and underarm are open when normally using, and for the convenience of packed and transported and keeping, the underarm termination is provided with the U-loop cover when not using, and two arms is opened after being inserted in the upper arm termination.Therefore, during use ring set is pulled out, suspend to use or ring set is written into to operate with two hands during keeping and finish very sense inconvenience.

Summary of the invention

The purpose of the utility model is to remedy above-mentioned deficiency, provides a kind of upper and lower arm not fragile and durable in use to society, and upper and lower arm opening and closing are easy to operate, the manual pulling rivet rifle that one-hand operation is finished.

The technical solution of the utility model is finished like this: it comprises upper arm, underarm, arm axle, blind rivet mechanism.It is characterized in that the arm axle place establishes upper arm and reinforces long cover and underarm reinforcing cover.The trombone slide sleeve place of the trombone slide cover connecting portion of upper arm and blind rivet mechanism is provided with upper arm and reinforces cover.A upper and lower arm locking mechanism is set at the back of upper arm.

Described upper and lower arm locking mechanism comprises: be placed in the shrinkage pool in upper arm back, the push button of bottom U font, be fixed on the underarm, can partly hang the L shaped frame that colludes that closes, the extension spring on the push button with push button U font.The shaped design of the handle portion of described underarm becomes the pliers handle of common practicality similar, and is with the garment bag that increases frictional force.

Because the axle place of the trombone slide cover connecting portion of upper and lower arm connecting portion and upper arm and blind rivet mechanism all is provided with and reinforces cover, this makes the damage not easy to crack of upper and lower arm forced section, thereby has reached whole the long-lived purpose of pulling rivet rifle.Again because, installed a upper and lower arm locking mechanism, this mechanism has replaced the U font ring set between the upper and lower arm of prior art, makes the locking of upper and lower arm and unblanks to implement one-handed performance.Therefore, no matter be operation, pausing operation and keeping are all very convenient.

The specific embodiment

Further describe the utility model below in conjunction with accompanying drawing.The connecting portion of upper arm 9 and underarm 10 is established arm axle 13 (seeing Fig. 1, Fig. 3) in the present embodiment.Blind rivet mechanism comprises: fixture block 1, top pine nail 2, compression spring 3, trombone slide cover 4, trombone slide sleeve 12, (Fig. 2) upper arm 9, underarm 10.Arm axle 13 places establish upper arm and reinforce trombone slide sleeve 12 places that long cover 14 and underarm add cover 15 (Fig. 3) upper arm and the trombone slide cover connecting portion of blind rivet mechanism and upper arm is set reinforces and overlap 11 (Fig. 2).A upper and lower arm locking mechanism is set at the back of upper arm.Locking mechanism comprises the push button 7 of the bottom U font that is placed in the shrinkage pool of upper arm back, is fixed on the underarm, can partly hangs the L shaped frame 8 that colludes that closes, the extension spring 6 on the push button with push button U font.The shape of the handle portion of underarm is similar to common pliers handle, and is with the garment bag 16 that increases frictional force.

When present embodiment uses, hold underarm 10 for available one, press down upper arm 9 simultaneously, extension spring 6 is just drawn back the U-shaped portion of push button 7 from the L shaped frame 8 that colludes, and torsion spring 5 opens upper and lower arm 9,10.During end of operation, with pointing to last push button 7, the U-shaped of push button 7 hook part just lumps together with L shaped frame 8 extensions that collude, and upper and lower arm is tangled.Like this, just can singlehanded switch pulling rivet rifle.When the pulling rivet rifle used, upper and lower arm 9,10 opened.Pulling rivet is filled in from muzzle 17, and direct sending is to fixture block 1 place.When upper and lower arm was pinched, the front end of upper arm 9 was a fulcrum with arm axle 13, by trombone slide sleeve 12 trombone slide cover 4 was upwards drawn.At this moment, compression spring 3 compressions, fixture block 1 closure clenches the pulling rivet upper end with trombone slide cover 4 upwards, and the pulling rivet core is pulled out.When openhanded opening, torsion spring 5 opens upper and lower arm, and simultaneously, compression spring 3 resets, and trombone slide cover 4 moves down, and fixture block 1 send under nail 2 effects on the top and opens, and the pulling rivet core comes off thereupon.So whenever, draw a pulling rivet, upper and lower arm connecting portion and upper arm and trombone slide cover connecting portion will stand a subgravity.The utility model is provided with at these connecting portion places reinforces cover 11,14,15, and therefore, the contact area of connecting portion increases, and then makes upper and lower arm not fragile with axle, thereby makes the utility model durable in use.
