FIG. 1 is a perspective view of the present invention;
FIG. 2 is a front view of the present invention;
wherein, the device comprises a base 1, a clamping head 2, a pin shaft 3, a mandril screw 4 and a protective rubber sleeve 5.
Detailed Description
The following further describes the embodiments of the present invention with reference to the drawings.
As shown in fig. 1 and 2, the quick clamping device is composed of a base 1, a clamping head 2, a pin shaft 3, a mandril screw 4 and a protective rubber sleeve 5. The lower bottom plate of the base 1 is provided with 4 countersunk head through holes, the base 1 can be arranged at the appointed position of the mounting plate of the electrical property testing turntable through screws, the upper end of the base 1 is provided with a small semi-circular arc with the radius of 6.8mm, and the side surface of the base 1 is provided with a clamping head 2 mounting lug; the clamping head 2 is of an L-shaped structure, wherein a small semicircular arc with the radius of 6.8mm is arranged at the end part of the long arm, a threaded through hole is formed in the end of the small arm, and lugs which are bilaterally symmetrical are arranged at the joint of the long arm and the short arm. The clamping head 2 is arranged on the base 1 through a pin shaft 3, and the clamping head 2 can rotate around the pin shaft 3 within the range of 0-48 degrees; the ejector rod screw 4 is in threaded connection with the clamping head 2, and the top end of the ejector rod screw 4 is attached to the bottom surface of a deep counterbore with the depth of 1mm on the side surface of the base 1 in a clamping state. The mandril screw 4 is provided with a manual screwing head, so that rapid clamping operation without tools is realized; the thickness of the protective rubber sleeve 5 is 0.5mm, and the protective rubber sleeve is 2 in total and is respectively stuck to the clamping head 2 and the base 1.
