Rivet tool

Abstract

The utility model provides a rivet tool comprising a body, a pulling block and a pressing handle. The pulling block can move in the body up and down selectively under the pressing action of the pressing handle so as to drive a rivet core of a rivet on a work piece through the pulling block, and a rivet cap of the rivet can generate riveting action relative to the work piece. The rivet tool is characterized in that a push roller is pivoted to the front end of the pressing handle via an axle, and when the pressing handle is located at the position about to press down to drive the pulling block to move up, the contact point of the push roller with a butting piece of the pulling block is just located on the vertical axis on which a rivet clamping jaw of the pulling block grips the rivet core of the rivet. Therefore, deflection cannot be generated on the pressing-down action of the pressing handle, force is applied extremely evenly during action, riveting effect and validity of the rivet cap of the rivet can be improved effectively, and convenience in operation is improved; meanwhile, vibration is not easy to generate, abrasion of parts is reduced, and service life is prolonged.

Description

technical field [0001] The present invention belongs to a hand tool used for rivets, and specifically refers to a rivet pulling tool that can maintain uniform force, so as to avoid deflection during the application, improve the stability of the joint, and prolong the service life of the machine parts . Background technique [0002] Press, a rivet is an appliance that can fix two or more work pieces together. It mainly includes a nail core and a nail cap. The other end of the rivet core can be clamped by a rivet pulling tool, and then pulled. Nail core, to force the head of the nail core to stretch the nail cap, so that the work piece is tightly fixed between the retaining edge of the nail cap and the nail cap body that is only stretched apart by the head of the nail core. Because the nail pulling tool is extremely convenient to use and has good effects, its development is becoming more and more complete, such as China Taiwan Patent Gazette Announcement No. 284006, Announcem...

Problems solved by technology

However, when the handle is pushing the pull block, the push block of the handle and the contact piece of the pull block are in offset contact, so that the line of force and the axis of the pull nail are misaligned, so that the action of the pull block produces a biased force. It affects the smoothness and stability of the action, and it is easy to cause wear and damage to the parts and shorten its service life

[0005] Through the above description, it can be understood that due to the imperfect design of the existing rivet tools, there are problems and shortcomings such as easy deflection, uneven force application and easy damage, which affect the effect of riveting and stability, so how to solve this problem is what the industry is eager to break through

[0006] In view of this, the inventor of the present invention has conducted in-depth discussions on the problems faced by the above-mentioned nail pulling tools based on years of experience in research and development and manufacturing of related industries, and actively sought solutions. After long-term hard research and trial production, he finally succeeded. Developed a structure of the pull nail tool that does not sway, so as to overcome the inconvenience and trouble caused by the uneven application of force
