The present invention relates to a straight edge clamp that has a clamping head assembly and a stop assembly mounted upon the body of the straight edge. The head and stop are not connected together and the stop assembly is free to move with respect to the head assembly. The straight edge clamp body includes at least two sections that are hinged together to allow the sections to be folded upon one another when not in use and unfolded when in use.

A clamp apparatus includes a pair of first and second clamp arms supported rotatably on a body. The clamp apparatus also includes a manual release mechanism capable of manually releasing a clamped state in the case that an output from a drive unit to the first and second clamp arms is stopped and the clamped state of a workpiece is locked. The manual release mechanism includes a release lever disposed rotatably on a first plate body. By an operator operating the release lever to thereby rotate the release lever, a block body of a driving force transmission mechanism is pressed and moved upwardly, and pressing forces applied to the first and second clamp arms in widthwise outside directions thereof by a pair of rollers, are released. Consequently, gripping members of the first and second clamp arms are rotated in directions away from each other to thereby cause an unclamped state.

The subject invention provides a means to tie a fly pattern for a fishing method by means of the fly tying vise mechanism. In general, the invention employs technology that allows the individual to position the various parts of the vise in multiple ways to achieve virtually unlimited angular positioning of the jaws. The invention employs an offset cam that allows for an adjustable friction applied to the hook jaw mechanism that is attached to a long vertical post, mounted on a heavy pedestal, providing stability for the vise. The pedestal employs several applications for storing or attracting tools and hooks and magnetizing jaws. The offset cam can be adjusted up and down and rotate 360 degrees horizontally around the vertical post; can be rotated 360 degrees vertically to turn the cam from a horizontal to a vertical position; allows the jaws to be moved up and down, relative to the cam to accommodate different sizes hooks; and, allows the jaws to rotate 360 degrees. The invention also employs a swiveling, vertically adjustable back snatch, which is a flexible arm that is used to hold the bobbin thread holder or material pliers that hold feathers and other material during the tying process.

The present invention concerns a device for performing operations on timepiece movements including a plate mounted on a stand, said plate including at least one storage area capable of receiving timepiece movement components, characterized in that said plate further includes at least one work support provided with means for holding timepiece movements, the work support being arranged to form an extension so as to facilitate access to said movement.

A workpiece clamp device capable for changing clamp angle is arranged on a base plane and comprises a first and a second movable blocks, a driving block, at least one first and at least one second elastic members, at least one first and at least one second cylinders, and at least one third and at least one fourth elastic members. Since the first and the second cylinders are slightly rotatably and detachably respectively embedded in the first and the second embedding grooves to make the first and the second rough surfaces be exposed and the elasticity of the third and the fourth elastic members is cooperated therewith, the first and the second rough surfaces are slightly fine-tuned based on the shapes and sizes of the workpieces so as to be suitable for clamping and fastening the workpieces with different shapes.

A high-precision two-part flat chuck device includes: a base, a cylinder, a sliding plate, a first clamping plate and a second clamping pate. A piston rod of the cylinder is connected with the sliding plate. Precision sliding rails are arranged at two sides of the base, and two sides of the sliding plate are respectively matched with the precision sliding rails in a sliding manner. An accommodating groove is arranged in a middle part of the sliding plate. The first and second clamping plates are symmetrically distributed in the accommodating groove along a center of the sliding plate, and a spring is arranged between the first and second clamping plates. Side surfaces of the first and second clamping plates are inclined planes, and chucks matched with each other are arranged at end parts of the first and seconding clamp plates.

In a clamping fixture 1, in particular a vice, with a housing (2) in which a guide track (10) is provided and with at least one base jaw (3, 4) to each of which a clamping jaw (6, 7) can be attached, the cavities or air gaps (21) between the inner wall of the guide grooves (10) and the base jaws (3, 4) should be completely covered.

This is achieved in that a seal (11) is inserted into each of the air gaps (21) existing in the housing 2 between the base jaw (3, 4) and the inner wall of the guide track (10) as well as in the parting plane between the base jaws (6, 4) and at the face ends (16) in the area of the guide track (10) running there, and that the particular seal (11) is held in a specified position by means of a support strip (12).

A clamp includes a fixed jaw assembly which has a fixed jaw and a movable jaw assembly which has a movable jaw. The movable jaw assembly is movable with respect to said fixed jaw assembly so that the movable jaw moves with respect to the fixed jaw. A handle is rotatably connected to the fixed jaw assembly, the handle includes a cam which moves the movable jaw assembly. When the handle is placed in a first rotational position the jaws are open and the movable jaw is disposed a first distance from the fixed jaw. When the handle is placed in a second rotational position the jaws are closed and the movable jaw is disposed a second distance from the fixed jaw, the second distance being less than the first distance. An adjustment is provided for changing both the first and second distances.
