To achieve these goals, the utility model employs following technical scheme：
Design it is a kind of can automatic open-close tongs, including two corpus unguis, and two corpus unguis pass through hinge, the corpus unguis
Both sides be equipped with long strip block, two long strip blocks are connected by multiple connecting plates, and the long strip block opens up close to the side of corpus unguis
There is chute, two sliding blocks are provided between two chutes, and the both ends of sliding block are slided respectively along the surface of two chutes, two cunnings
Second spring is installed, the side of the corpus unguis offers the strip hole with sliding block Matching installation, and the surface of sliding block between block
Slided along the inner surface of strip hole, there is connecting rod on the top of the corpus unguis by hinge, set above the connecting rod
There are mounting blocks, the one end of the connecting rod away from corpus unguis is hinged by bearing pin and mounting blocks, between the mounting blocks and long strip block
Connected by expansion link, and the first spring be socketed with expansion link, and the both ends of the first spring respectively with mounting blocks and long strip block
Connection.
Preferably, the connecting plate is provided with two, and is separately mounted on the symmetrical end face of long strip block two.
Preferably, the expansion link includes sleeve pipe, and one end of described sleeve pipe is connected with mounting blocks, the other end of described sleeve pipe
Opening is inserted with slide bar, and the one end of the slide bar away from sleeve pipe is connected with long strip block.
Preferably, the top of the mounting blocks is provided with draw ring, and draw ring is located at the center of mounting blocks.
The utility model proposes it is a kind of can automatic open-close tongs, beneficial effect is：By add the first spring and
Second spring so that chela can open automatically under the force of a spring in the state of object is not clamped, so be easy to pair
Blank is lifted by crane, but also avoids the artificial operation of work, and the effect of protection is served to staff；Slided by adding
Block, chute, strip hole and expansion link, be easy to carry out corpus unguis it is spacing, so as to improve corpus unguis stability when mobile.This practicality is new
Type is simple in construction, easy to use, not only facilitates chela being opened automatically in the state of object not clamp, so as to improve to blank
The efficiency of part lifting, moreover it is possible to improve stability of the tongs in regulation.
