Cooling water channels are arranged on the clamping jaw bodies. The overall flexible clamping jaw can achieve switch between flexibility and rigidity, avoids direct influence of a vibration environment on a robot and an end executor, improves the stability of the end executor and the robot and prolongs the service lives of the end executor and the robot; the position of the clamping jaw can be accurately located; the cooling water circularly flows to cool the clamping jaw, the forging clamping jaw is kept ata low temperature, and continuous work of the clamping jaw is guaranteed.

The invention relates to a pin for an illuminating bus duct plug box. The pin comprises an elastic part, a supporting column and a base. An elastic base of the elastic part is fixed in an elastic part clamping groove of the supporting column in a clamping mode, and the supporting column is fixed in a supporting column clamping groove of the base in a clamping mode. The elastic part, the supporting columns and the base are fixed into a whole through bolts. The pin for the illuminating bus duct plug box is simple in structure, good in stability, firm in plugging, safer and more reliable. Meanwhile, cost is further lowered.

The invention discloses a surgical forceps, which comprises a first forceps arm and a second forceps arm. The front ends of the first forceps arm and the second forceps arm are respectively provided with mutually clamping forceps heads. The bottom of the end is respectively connected with the two handles by bolts, and the two handles are connected through the cross rotation of the rotating shaft. There is a ring on the two handles which is easy to grasp. A projection freely sliding in the groove is provided, a stop lock is provided between the two handles, and a buckle for fixing the stop lock is provided on one handle. The invention is suitable for operations at various positions, has strong holding force, adjustable clamping width, wide application range, and is worthy of popularization.
