The spring and the threaded sleeve are sleeved between the handles, wherein the spring is close to the second flange, and the sleeve is sleeved on the straight ejector rod through the threaded sleeve, wherein the The spring and the flange two are located inside the sleeve, and the handle is located on the side away from the L-shaped push rod.

Preferably, both the first flange and the second flange are in-line shape.

Preferably, the first casing and the second casing are of the same specification.

Preferably, the fastener is a limit bolt, and the round rod can be fixed in the casing by screwing the limit bolt, and one end of the L-shaped ejector rod is fixed in the casing. Pipe two.

The beneficial effect of the adjustable clamping device provided by the present invention is that it can be adjusted according to the size of the clamped structure, and has a wide application range; the types of clamping devices are reduced, thereby reducing costs; the plug-in ejector rod is adopted Clamping is more convenient to use and improves efficiency.

detailed description

In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be described in more detail below in conjunction with the drawings in the embodiments of the present invention. In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of the invention. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

The adjustable clamping device of the present invention will be described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the adjustable clamping device includes: L-shaped ejector rod 1, casing one 2, threaded rod 3, ejector rod sleeve 4, straight ejector rod 5, threaded sleeve 6, spring 7, casing two 8, fastener.

Casing one 2 and casing two 8 are threadedly connected to the threaded rod 3, and one end of the L-shaped ejector rod 1 is sleeved inside the casing two 8 and fixed by fasteners. The selection of fasteners in this embodiment is limited. The position bolt 9 is fixed by screwing the limit bolt 9, the ejector rod sleeve 4 is L-shaped, a part is a circular sleeve 41 with an inner diameter, and the other part is a round rod-42, wherein the inner wall of the sleeve 41 is along the radial direction There is a flange-411, the flange-411 of this embodiment is preferably arcuate, see Figure 3 and Figure 4, the round rod-42 is sleeved inside the sleeve-2 and fixed by fasteners, the present embodiment Fastener also selects limit bolt 9 for use, fixes by screwing limit bolt 9, can adjust the distance between two sleeve pipes (sleeve pipe one 2 and sleeve pipe two 8) by thread, can be adjusted by screwing limit bolt 9 Adjust the length of the L-shaped ejector rod 1 in the casing of casing 2 8, and the length of the round rod 1 42 in the casing of casing 1 2 can be adjusted by screwing the limit bolt 9. In actual operation, casing 1 2 and casing 2 Pipe two 8 can adopt the sleeve pipe of the same specification (that is, identical).

As shown in Figures 2 and 3, a part of the straight ejector rod 5 is a round rod 2 51, and the other part is a detachable handle 52. On the round rod 51, there is a flange 2 511 in the radial direction. Flange 2 511 is preferably in-line, see Figure 2 and Figure 4, unscrew the handle 52, from one end of the handle 52 of the straight ejector rod 5, the spring 7 and the threaded sleeve 6 are sequentially sleeved to form a whole, wherein the spring 7 is close to the convex On one side of flange two 511, the assembled whole is inserted from one side of the sleeve 41 and passed out from the other side, wherein the area of flange one 411 in the sleeve 41 will not hinder the passage of flange two 511, because There is only one round hole on the side of the sleeve 41 to pass through the straight ejector rod 5, and then the flange 2 511 blocks the spring 7 so that it is located inside the sleeve 41, and then the handle 52 is tightened and the device is installed. 1 side of the L-shaped ejector rod.
