Detailed Description

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

Referring to fig. 1-3, automatic locking clamp, it includes threaded sleeve 3, the equipartition is provided with a plurality of fixed lug seats 4 on the outer wall of threaded sleeve 3, the inside of threaded sleeve 3 installs through screw thread transmission cooperation and pushes up tight screw rod 2, every fixed lug seat 4 is last and is located its both sides and articulates through first articulated bolt 13 has first link plate 9 and second link plate 14, the end of first link plate 9 and second link plate 14 is articulated through the middle part of second articulated bolt 16 with clamping jaw connecting rod 12. Through adopting the automatic locking clamp of above-mentioned structure, can be used for pressing from both sides tight use of work piece, and then guaranteed the convenience and the reliability of clamping operation, because, at the tight in-process of clamp, through driving top tight screw 2, the bottom of top tight screw 2 will contact the cooperation with the top terminal surface of work piece, meanwhile the bottom of clamping jaw connecting rod 12 will contact the cooperation with another terminal surface of work piece, and then with the effectual clamp of work piece under the clamp force, because clamping jaw connecting rod 12 articulates and installs between first link 9 and second link 14, therefore, it constitutes many link structures, constitute lever mechanism when pressing from both sides tightly like this, and then increased its clamp force, the tight reliability of clamp has been guaranteed.

Furthermore, the top end of the jacking screw rod 2 is provided with a hexagonal head 1 used for rotating the jacking screw rod, a conical end 15 is processed at the bottom end of the hexagonal head, and the jacking screw rod 2 is of a full-thread structure. The tight screw rod in top 2 through above-mentioned structure can provide the clamp force through screw thread transmission, and the tight screw rod in drive top 2 that can be convenient through hexagonal head 1 moreover rotates, adopts the toper end 15 can strengthen the clamp force between its and the work piece moreover. The structural design of the full thread can conveniently control the stroke of the full thread.
