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

Embodiment 1

[0038] Such as Figure 1 to Figure 8 Shown: a kind of small and exquisite type double handle riveting gun, including riveting gun seat 6 ( figure 1 , 5), the rivet adjustment mechanism arranged at the front end of the rivet holder 6, the rivet gripping mechanism installed in the rivet adjustment mechanism, one end of which is respectively connected to the two sides of the rivet holder 6 through the screw shaft 5 The two hinged handles 9 of the rivet holder are movably inserted into the pull rod 8 in the central hole 12 of the rivet holder 6 . The whole of the pull rod 8 and the fixed piece 7 and one end of the pull rod telescopic mechanism on the end of the pull rod are respectively hinged to both sides of the fixed piece 7, and the other end is respectively close to the screw shaft 5 and hinged to the connecting rod 20 of the head of the handle 9. All are arranged in the cavity of described riveting gun seat 6, and the length of described pull rod 8 is shortened; Both sides...

Embodiment 2

[0051] Another situation is: sometimes when a product with a longer adjustment seat of the rivet adjustment mechanism at the front of the riveting gun is required, the pull rod needs to be extended to the rivet during operation. At this time, most of the pull rod 8 and its rear part, The fixed piece 7 and one end of the pull rod telescopic mechanism at the end of the pull rod are respectively hinged on both sides of the fixed piece 7, and the other end is respectively close to the screw shaft 5 and the connecting rod 20 at the head of the handle 9 is hinged. Inside the rivet gun seat 6 cavities. The pull rod still needs to keep the original length, and the front part of the pull rod still exposes the rivet gun seat, and other structures are the same as in embodiment 1.

[0052] But because the outer layer of the part of the front part of the tie rod exposed to the rivet gun seat is covered by the catch seat and the adjustment seat, the front part of the tie rod cannot be direc...

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 riveter seat. 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 in the 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 ...
