Small and skillful dual-handle hand riveter

Abstract

The invention discloses to a small and skillful dual-handle hand riveter, which comprises a riveter seat, a rivet adjusting mechanism, a rivet gripping mechanism, two handles and a pull rod, wherein the rivet adjusting mechanism is arranged at the front end of the riveter seat, the rivet gripping mechanism is installed in the rivet adjusting mechanism, one end of one handle and one end of the other handle are respectively hinged with the two sides of the riveter seat, and the pull rod is movably inserted in the center hole of the riveter seat. The invention is characterized in that all or large part of the pull rod is provided with a rear part, and the pull rod, the fixing piece of a pull rod telescopic mechanism arranged at the end of the pull rod and connecting rods arranged on the two sides of the fixing piece and respectively hinged with the heads of the handles are arranged in the cavity of the riveter seat; and handle matching grooves are arranged on the two sides of the riveterseat. The invention has the advantages that since the length of the handles is shortened, all or large part of the pull rod is provided with the rear part, and the pull rod, the fixing piece of the pull rod telescopic mechanism arranged at the end of the pull rod and connecting rods arranged on the two sides of the fixing piece and respectively hinged with the heads of the handles are arranged inthe cavity of the riveter seat, the gripping force and the stability of the hand riveter are greatly improved, the appearance is tidier and cleaner, the use is handy and ingenious, and the carrying, the packaging and the transportation are convenient.

Description

technical field [0001] The invention relates to a riveting gun, in particular to a compact double handle riveting gun. Background technique [0002] Blind rivets are a type of rivets used for single-sided riveting. This type of rivet is especially suitable for riveting occasions where it is inconvenient to use ordinary rivets, so it is widely used in construction, automobiles, ships, aircraft, machines, electrical appliances, furniture and other products. Among them, the open type oblate head blind rivets are the most widely used, the countersunk head blind rivets are suitable for riveting occasions where the surface needs to be smooth, and the closed blind rivets are suitable for riveting occasions requiring higher load and certain sealing performance. However, this type of rivet must be riveted using a special tool - a riveter. The current riveting guns are divided into manual riveting guns, electric riveting guns and pneumatic riveting guns. Among them, manual riveting ...

AI Technical Summary

Problems solved by technology

Longer handles and pull rods not only increase the length of the entire riveting gun, resulting in an increase in its volume, which is not convenient for smart use, carrying, packaging and transportation, but more importantly, the front and rear ends of the pull rod protrude from the riveting gun seat In addition, when the rivet gun is operated, the stability of the pull rod is poor during telescopic activities, and it is prone to offset and skew, which affects the working efficiency of the rivet gun.

In addition, the rear part of the tie rod and the fixed piece and connecting rod of the pull rod telescopic mechanism are all exposed outside the riveting gun seat, which makes the product appear messy and the overall appearance is not neat and clean.

[0004] In addition, the three-lobed grasping piece of the rivet grasping mechanism is obliquely inserted into the inner cavity of the grasping piece seat, and the grasping force of the grasping piece to the rivet is not uniform enough during work, and the grasping force is affected.

The gripper is easy to slide in the gripper seat, resulting in poor stability and orientation, and the gripper will also be dislocated and stuck
