Double handle hand riveter

Abstract

The invention discloses a double handle hand riveter comprising a riveter base, a regulating mechanism, a riveter holding mechanism, one end of which is hinged with two handles on both sides of the riveter base and a tie bar in a central hole of the riveter base, characterized in that rear end of the tie bar is provided with a fixed groove embedded with a fixed piece, both sides of which are respectively connected with the handles via a connecting rod; one end of the collecting rod is connected with the fixed piece via a second screw shaft and the other end is hinged with the handle. Handle matching grooves are arranged on both sides of the base. The handles are respectively hinged with the riveter base via a first screw shaft in the handle matching groove. The connecting rod is hinged with the handle via a pin rod. The hand riveter can be handle screw by replacing riveter holding mechanism with a screw holding mechanism. Manufacturing process of the fixed groove, the tie bar and the fixed piece on the tie bar is simple and reduces cost. Due to rational connection among the collecting rod, the handle and the riveter base, volume of the invention is reduced.

Description

technical field [0001] The invention relates to a riveting gun, in particular to a double handle riveting gun. Background technique [0002] Rivet guns can be divided into rivet guns and rivet nut guns. Generally speaking, the rivet gun uses the core pulling rivet for riveting; the rivet nut gun uses the rivet nut for riveting. [0003] Core-pulling rivets are a kind of rivets for single-sided riveting. This kind of rivets are especially suitable for riveting occasions where it is inconvenient to use ordinary rivets. Therefore, they are widely used in construction, automobiles, ships, aircraft, machines, electrical appliances, furniture and other products. . Among them, the open type oblate head core pulling rivets are the most widely used, the countersunk head core pulling rivets are suitable for riveting occasions where the surface needs to be smooth, and the closed type core pulling rivets are suitable for riveting occasions requiring higher load and certain sealing per...

Problems solved by technology

[0006] However, the prior art has the following defects: since the fixed block suit is fixed on the lower part of the pull rod, a perforation suitable for the pull rod must be provided on the fixed block, the thickness of the fixed block must be matched with the connecting rod, and one end of the pull rod must be To prepare the thread, the inner layer of the thread must also be equipped with a back hole for the rivet to pass through. Therefore, the manufacturing process of the tie rod and the fixing block is relatively complicated, resulting in high cost

According to the principle of leverage, the farther the distance between the two screws is, the length of the handle as the force arm must be lengthened, otherwise it will be very laborious to use

The lengthening of the handle will inevitably increase the volume of the riveting gun, resulting in an increase in production costs, and it is not easy to pack, transport and carry
