The squeezer holder device also provides convenient storage for a hand squeezer and associated dies. The central feature of the invention is the simple slot and die holders designed into a single block. The squeezer holder device allows the user to position a squeezer on any benchtop at a user selected orientation. The squeezer holder device enables accurate control of parts with one hand throughout squeezer operation by using the table surface to operate the lower squeezer lever. The squeezer holder device can be easily slid around a benchtop with the squeezer and dies between operations. When squeezer use is completed the squeezer holder device holds the squeezer in an upright space saving position with associated dies.

The present invention discloses a one-hand handled riveter, which includes a housing with a left handle on the bottom, and a right handle. The mentioned left handle and right handle are all covered by a handle cover. The mentioned housing is installed with a rivet head and the rivet head is equipped with a pull rod on the rear end. The right handle is connected to the pull rob by the top end. Both sides of the top end of the right handle, are equipped with a support arm. The support arms are connected with the pull rod through a positioning shaft by the top end, and the two support arms are connected to a connecting rod through a pin shaft by the bottom end. And a connecting shaft is arranged to the end of the two connecting rod far away from the support arm. Two L-shaped connecting pieces are respectively connected to two ends of the connecting shaft. A connecting hole is arranged to the front and rear ends of the L-shaped connecting piece, and the connecting shaft passes one of the holes. And the rear end of the L-shaped connecting piece is connected to the fixing seat on the rear end of the pull rod by screw connection. The invention can achieve the working mode for screw riveter and nut riveter by selecting the installation position of the connecting hole on the L-shaped connecting piece.

The invention relates to a riveting tool for setting blind rivet nuts and/or blind rivet screws, comprising a drive piston which is able to be hydraulically adjusted from an initial position toward an end position, a pull rod which is releasably and operatively connected to the drive piston and which is able to be adjusted by the drive piston from a rivet receiving position into a setting position and a coupling element fixing the pull rod and a drawing mandrel to one another in the longitudinal axial direction. In order to provide a riveting tool of the type mentioned above by which uniform setting processes of rivets may be carried out with a high degree of repeated accuracy, it is provided that the riveting tool for fixing the setting position has an adjusting unit with a stroke-limiting element which is axially adjustable relative to the coupling element in the longitudinal axial direction of the pull rod, said stroke-limiting element being in engagement with the coupling element via a stop surface in the setting position.

The present invention discloses a hand riveter and relates to the field of hand-operated tools, and the hand riveter comprises a first handle, a second handle and a clamping and pulling mechanism, wherein the second handle is capable of rotating around a pivoting shaft with respect to the first handle; the second handle is separated into a force applying end and a warping end by the pivoting shaft, and the warping end and the clamping and pulling mechanism are connected via a connecting shaft; when the force applying end of the second handle is rotated and opened with respect to the first handle, the warping end of the second handle drives the clamping and pulling mechanism to move in a rivet-driving direction; and when the force applying end of the second handle is rotated and closed with respect to the first handle, the warping end of the second handle drives the clamping and pulling mechanism to move in a rivet-pulling direction. According to rational arrangements of the present invention, the hand riveter is labor-saving and is comfortable to hold during pull riveting.

The invention relates to a riveting tool for setting blind rivet nuts and/or blind rivet screws, comprising a drive piston which is able to be hydraulically adjusted from an initial position toward an end position, a pull rod which is releasably and operatively connected to the drive piston and which is able to be adjusted by the drive piston from a rivet receiving position into a setting position and a coupling element fixing the pull rod and a drawing mandrel to one another in the longitudinal axial direction. In order to provide a riveting tool of the type mentioned above by which uniform setting processes of rivets may be carried out with a high degree of repeated accuracy, it is provided that the riveting tool for fixing the setting position has an adjusting unit with a stroke-limiting element which is axially adjustable relative to the coupling element in the longitudinal axial direction of the pull rod, said stroke-limiting element being in engagement with the coupling element via a stop surface in the setting position.

The present invention discloses a one-hand-handled rivet gun, which has a handle seat with a through hole, a folding mechanism hinged to the handle seat and a pulling rod connected to the folding mechanism. The mentioned pulling rod is coated by a housing, and is equipped with a riveting gun tip assembly on the front end. A fixed sleeve is mounted on the front end of the housing of the pulling rod, and a guiding nipple is mounted on the front end of the fixed sleeve. The mentioned folding mechanism comprises two folding rod assemblies symmetrically mounted behind both sides of the rear end of the pulling rod, and the two folding rod assemblies include a front curved link and rear curved link hinged to each other. A handle cover is connected to the rear end of the rear curved link, and the front curved link is fixed to the pulling rod by the front end and hinged to the front end of the handle seat. Therefore, the invented one-hand-handled rivet gun can be used with only one hand, which is easy for people to use.

The present invention discloses a nut riveter comprising a front riveter seat with a cavity, a rear riveter seat arranged in the cavity of the front riveter seat and located at a rear end of the front riveter seat, a nut adjusting mechanism arranged at a front end of the front riveter seat, a nut riveting rod installed in the nut adjusting mechanism, wherein two sides of the rear riveter seat are each connected to a handle through a connecting rod; a pull rod seat located in the cavity of the front riveter seat, wherein a pull rod is inserted into the pull rod seat, wherein a rear end of the pull rod is connected with a pull rod retractable mechanism.
