Drawings

Fig. 1 is a perspective view of a clamping device of the present invention;

FIG. 2 is an exploded view of the present invention;

FIG. 3 is a view showing a state of the clamping device of the present invention;

in the figure, 1 is a clamping seat, 2 is a clamping head, 3 is a nut, 4 is a screw, 5 is a movable groove, 6 is a sliding seat, 7 is a through hole, 8 is a table board, and 9 is a space.

Detailed Description

The following describes embodiments of the present invention in detail with reference to the accompanying drawings.

The first embodiment is as follows: referring to fig. 1-3, a clamping device comprises a fixed clamping base 1 and a movable clamping head 2, wherein an area for clamping an object is formed between the clamping base 1 and the clamping head 2. In order to control the movement of the clamping head 2, the device also comprises a nut 3 and a screw 4; the clamping seat 1 is connected with a sliding seat 6 which is of an integrated structure with the clamping seat 1, the sliding seat 6 comprises a movable groove 5 used for the axial movement and rotation of a screw 4, the radial end of the screw 4 is fixedly connected with the clamping head 2 into an integrated structure, and the axial end of the screw penetrates through the clamping seat 1 along the movable groove 5 and then is in threaded connection with the nut 3.

As shown in fig. 3, during installation, the nut 3 rotates to drive the screw 3 to move downwards to enable the clamping head 1 to move to the outer side of the movable groove 5, and the clamping head 1 cannot be limited by the movable groove 5, so that the clamping head can rotate axially relative to the screw 4, for example, the clamping head 1 rotates 90 degrees, the clamping head 1 just can be inserted into a gap of a table, then the clamping head 1 rotates reversely to rotate back, the screw 3, the clamping head 1 and the nut 3 are lifted upwards, the clamping head 1 falls into the movable groove, at the moment, after the nut 3 is screwed by hands to enable the nut 3 to be screwed by hands to contact with the clamping head 1 to be stressed, axial movement can only be achieved due to the fact that the clamping head 1 falls into the movable groove and cannot rotate, and the table 8 can be clamped. Therefore, the device can be inserted into a narrow space 9 for use, thereby improving the practicability.

The outer surface of the nut 3 is provided with knurls, so that the friction force is increased, and the appearance is more attractive.

The clamping base 1 is provided with a through hole 7, and the screw 4 is positioned in the through hole 7.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and embellishments can be made without departing from the technical principle of the present invention, and these improvements and embellishments should also be regarded as the protection scope of the present invention.
