In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; the connection can be mechanical connection or communication connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1-2, in an embodiment of the present invention, a height-adjustable clamping device includes a loading table 2, and further includes a movable pressing plate 3, where the movable pressing plate 3 is in an i-shaped plate shape, and includes a web 31 and wing plates 32 symmetrically connected to two sides of the web 31; wherein, a plurality of notches 321 are horizontally arranged on the edge of the wing plate 32 along the length direction; the web plate 31 is provided with a waist hole 311 parallel to the wing plate 32; the adjusting mechanism 4 is further provided with a supporting rod 41 penetrating through the waist hole 311 and detachably connected with the placing table 2, a pressing rod 42 vertically sleeved on the periphery of the supporting rod 41, and a fastening piece 43 sleeved on the supporting rod 41. In this embodiment, the high support rod 41 is provided as a screw and the fastening member 43 is provided as a nut that matches the screw. An object 1 to be clamped is placed on the loading table 2 and is pressed by one end of the wing plate 32, two end parts of the pressing rod 42 fall into the corresponding notches 321, and the pressing rod 42 can be pressed by screwing the nut, so that the wing plate 32 presses the object 1.

Furthermore, a threaded counter bore 21 is formed in the mounting table 2, and the bottom end of the screw is in threaded connection with the threaded counter bore 21, so that the screw can be approximately vertically fixed on the mounting table 2, and the screw can provide a guide for the longitudinal displacement of the nut and the compression bar 42.

With reference to fig. 3, the pressing rod 42 includes a connecting block 421, and rod ends 422 coaxially connected to two sides of the connecting block 421; a through hole 4211 is formed in the connecting block 421, and the screw rod passes through the through hole 4211, and the two are connected in a clearance fit manner. The connecting block 421 is located between the two wings 32, suspended above the web 31.

Referring to fig. 4, in the present embodiment, the number of the notches 321 is five, and for better illustration, the five notches 321 are sequentially marked as a, b, c, d, and e from left to right, and they are in a semicircular shape matching with the outer peripheral profile of the rod end 422, so as to better support the rod end 422 and prevent slipping during clamping. Furthermore, the end of the wing plate 32 contacting the object 1 and the end contacting the loading platform 2 both have smooth-transition shape protrusions, so that the object 1 or the loading platform 2 is prevented from being damaged by excessive pressing of sharp edges and corners in the clamping process, and the pressure on the object 1 can be increased by the protrusions, so that the clamping is more reliable.

Referring to fig. 5-7, in use, the screw is first screwed into the screw counter bore on the platform 2, the movable pressing plate 3 and the pressing rod 42 are then sequentially sleeved on the screw, and finally the nut is screwed on the screw to complete the initial assembly.

As shown in fig. 5, the object 1 to be chucked is placed on the table 2, and one end of the flap 32 is pressed above the object 1. The object 1 can be firmly pressed against the mounting table 2 by moving the rod end 422 into the appropriate notch c according to the height of the object 1, screwing and pre-tightening the nut, pressing the pressing rod 42 downward with the nut, and applying the pressure applied to the pressing rod 42 to the wing plate 32.

When the height of the object 1 to be pressed is increased, the nut is screwed upwards in advance, a new object is placed under the end of the wing plate 32, the included angle between the wing plate 32 and the carrying table 2 is increased, the press rod 42 falls into the notch c (as shown in fig. 6), and the nut is screwed downwards to be pressed.

When the object 1 to be compressed is very high and the length of the screw is limited, the pressing rod 42 can be moved into the notch d or the notch e, so that the effective length X of the wing plate 32 is increased, and the adjustable included angle between the wing plate 32 and the loading table 2 is further increased, but the pressure applied to the object 1 by the wing plate 32 is correspondingly reduced, that is, the smaller the effective length X of the wing plate 32 is, the larger the pressing force is, and if the length of the screw is sufficient, the notch close to the object 1 is selected as much as possible. When the pressing rod 42 falls in the notch a, the object 1 having a very low height can be pressed while the pressing force is maximized.

It should be noted that, in this embodiment, the object 1 with a higher height can be clamped by replacing the longer screw, but replacing the screw is not recommended because it is more complicated and less convenient and quicker than directly moving the position of the pressing rod 42 in the notch.

Although the present description is described in terms of embodiments, not every embodiment includes only a single embodiment, and such description is for clarity only, and those skilled in the art should be able to integrate the description as a whole, and the embodiments can be appropriately combined to form other embodiments as will be understood by those skilled in the art.

Therefore, the above description is only a preferred embodiment of the present application, and is not intended to limit the scope of the present application; all changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
