  However, due to the large number of components of this type, assembly is difficult and the overall cost is high.

  The main purpose of the present invention is to improve the drive handle drive structure, reduce the number of necessary components when combining the drive handle, reduce costs, and make the overall assembly easier and faster. Provide the design. By forming the pushing protrusion mainly on the upper end of the integrally formed driving handle, the driving handle can be manufactured more compactly and easily, and the operating plate can be directly driven using the pushing protrusion. Furthermore, in combination with a release rod, the quick release of the stored energy of the clamp can be controlled. As a result, the overall components can be simplified, and there are advantages such as convenient combination.

  The next object of the present invention is to form an inverted T-shaped hole by connecting the working plate, the connecting hole, and the connecting rib, and each side of the connecting rib extends to form a horizontal shape. A staircase plate is formed, and a narrow plate is formed in the middle of the connecting rib. When combining through the connecting hole and the connecting rib, first pierce the connecting rib straight through the connecting hole, and then return it back to the original position to lock the horizontal stair plate at both ends to the connecting hole. Place and secure the connection ribs so that they do not flip up and down inside the connection holes, and provide a structural design of handheld tightening brackets to avoid abnormalities in the tightening brackets.

  The present invention mainly includes a moving shaft, an attachment handle, a drive handle, and a first tightening block base body. The moving shaft passes through the mounting handle, the driving handle, the first clamping block base body, the operation plate, and the locking plate, and the first clamping block base body and the mounting handle have a first clamping block and a first clamping block, respectively. 2 The clamping block is provided, the drive handle is pivotally mounted on the mounting handle by integral molding, the upper end has a push-in projection, the operating plate, the locking plate, and the spring are accommodated inside the mounting handle and released. It is pivotally connected to the rod, the upper end side of the operating plate presses against the pushing protrusion of the driving handle, the lower end portion of the locking plate is placed on the release rod, and the object of quick clamping can be achieved by pressing the driving handle.

  Since the present invention has the above-described configuration, it is possible to simplify the structure of the hand-held fastening bracket, simplify the assembly, and reduce the overall cost.

It is the combination solid figure of this invention. It is a three-dimensional exploded view of the present invention. It is combination sectional drawing by the normal state of this invention. It is the cross-sectional schematic by the operation state of this invention. It is the cross-sectional schematic by the discharge | release state of the storage energy of this invention.

  1 to 3 mainly includes a moving shaft 1, a mounting handle 2, a driving handle 3, and a first clamping block base body 4. One or more actuating plates 5, locking plates 6, springs 7, and release bars 8 are arranged inside the mounting handle 2.

  Among them, the moving shaft 1 passes through the attachment handle 2, the drive handle 3, the first tightening block base body 4, the operation plate, and the locking plate, respectively. The attachment handle 2 is a base body that penetrates the moving shaft 1, and the upper end portion extends to form a second fastening block 21, and the lower end extends to form a grip 22. The upper side of the inner wall passing through the moving shaft 1 is provided with spring accommodating grooves 23, 24, and the lower side of the inner wall is provided with another spring accommodating groove 25, and a side wall hole 26 is formed in the outer wall of the grip 22. The side forms a pivot hole 27.

  The drive handle 3 is an integrally formed handle base body, and has a pivoting hole 31 that forms a coupling manner with the mounting handle 2 at the upper end thereof, and the inner side of the upper end is an integrally formed push-in projection. A portion 32 (see FIG. 3) is provided, and a hole 33 penetrating the moving shaft is formed at a middle position.

  The first clamping block base body 4 is coupled through the moving shaft 1 and is provided with a first clamping block 41, and the first clamping block 41 is matched with the second clamping block 21 of the mounting handle 2. Yes.

  The one or more actuating plates 5 are made of hard steel pieces, have holes 51 as they are prepared for penetration of the moving shaft 1, and have lower end portions provided with coupling connection holes 52 for provisional coupling of the coupling ribs 53. Penetrates the moving shaft 1 in an oblique direction, the upper end presses against the pushing projection 32 of the drive handle 3, and the pushing plate 32 is used to directly prepare for driving the operation plate 5.

  The structure of the one or more locking plates 6 is similar to that of the actuating plate 5 and has a hole 61 so as to provide an oblique penetration by the moving shaft 1, and the lower end is connected with a connecting rib 53 to prepare for connection. A hole 62 is provided, and the lower end of the locking plate 6 is attached to the release rod 8.

  One or more springs 7 are respectively planted in the spring receiving grooves 23, 24, 25 of the mounting handle 2 and are respectively applied to the actuating plate 5 or the locking plate 6.

  The release rod 8 is pivoted and coupled to the pivot hole 27 of the mounting handle 2, one end of which is exposed in the side wall hole 26, and the other end hooks with the lower end of the locking plate 6.

  The hand-held fastening bracket made of the above-described components forms a displacement movement of the working plate 5 by pressing the driving handle, and the pushing protrusion 32 directly drives the working plate 5 to move the moving shaft 1 and energy. When the storage (or expansion) mode (see FIG. 4) is formed and the stored energy is released, the release plate 8 is gently pulled while being pressed so that the angle between the actuating plate 5 and the locking plate 6 is increased. Then, the engagement between the operating plate 5 and the locking plate 6 is released, and the stored energy (see FIG. 5) of the fastening bracket can be released to return to the standby state.

  According to the design of the present invention, the number of components required for the hand-held fastening bracket is reduced, the cost can be reduced, and the entire assembly is easier and more convenient. If the pushing protrusion 32 integrally formed on the upper end of the drive handle 3 is used, the operating plate 5 and the locking plate 6 can be directly driven, and the stored energy of the fastening bracket can be quickly released by using only the release rod 8. . The entire assembly is more compact, and the components can be simplified and the convenience of assembly can be achieved.
