The specific embodiment
The utility model is shown in Fig. 1,3,4, comprise stapling head 21, clamp seat 17 and clamp seat locking device, described clamp seat locking device comprises that the back side that is positioned at clamp seat 17 back sides and clamp seat 17 constitutes the wedge bar 13 and the locking bed 12 of dovetail groove jointly, it also comprises magnetic valve 1, is provided with horizontal columns consent, vertical column consent and air admission hole 16 in the described locking bed 12; Described magnetic valve 1 connects described air admission hole 16 by gas circuit 2;
Described vertical column consent and described horizontal columns consent are perpendicular, and are communicated with; The bottom of described vertical column consent is provided with the small stair hole, establishes top plug 5 in the described vertical column consent, and described top is filled in 5 bottoms and passed described small stair hole, fixedlys connected with described wedge bar 13 by screw 7;
Corresponding described horizontal plug hole site, the bottom of described plunger 11 is provided with deep-slotted chip breaker 18, is provided with steel ball 4 in the described deep-slotted chip breaker 18; Described top plug 5 is located at the below of described steel ball 4, and its end face contacts described steel ball 4; For ease of attachment screw 7, top plug 5 is established mesopore, and steel ball 4 contacts with the aperture of mesopore in fact, and the effect of location also can be played in the aperture to steel ball 4.
