Further, constitute by arc bolt, expanding spring and handle clamp plate including spacing bolt spare, the arc standing groove that sets up in the outer plugboard is arranged in to the arc bolt, the arc standing groove is worn out to arc bolt one end, and the other end is fixed in arc standing groove tank bottom through expanding spring, handle clamp plate end fixing is on the arc bolt, and the other end arranges the outer plugboard outside in, offer the shifting chute that is used for the handle clamp plate to reciprocate on the outer plugboard, shifting chute intercommunication arc standing groove.

Furthermore, including supporting to offer the bolt hole that is used for arc bolt interlude on the bolt spare on the nail seat subassembly axle head lateral wall.

The beneficial effects of the utility model are that, the utility model discloses a spacing coupling mechanism for chamber mirror cutting anastomat inserts its yaw pull rod and supports nail seat subassembly axle head in, the laminating of outer plugboard supports nail seat subassembly axle head outer wall on the yaw pull rod, and spacing bolt spare on it inserts and supports the bolt hole of seting up on the nail seat subassembly axle, realizes to its yaw pull rod and supports the axial connection between the nail seat subassembly, and this spacing coupling mechanism connects conveniently, stable in structure.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a cross-sectional view taken at A-A of FIG. 1;

fig. 3 is a partially enlarged view at B in fig. 2.

In the figure, 1, a swing head pull rod, 2, a nail abutting seat assembly, 3, an outer inserting plate, 4, a limiting bolt piece, 5, a bolt hole, 41, an arc-shaped bolt, 42, a telescopic spring, 43, a handle pressing plate, 44, an arc-shaped placing groove and 45, a moving groove are arranged.

Detailed Description

Fig. 1 is the utility model discloses a structural schematic diagram, a spacing coupling mechanism for cavity mirror cutting anastomat, including yaw pull rod 1, yaw pull rod 1 front end is connected with supports nail seat subassembly 2, yaw pull rod 1 is connected for interlude with supporting nail seat subassembly 2 link, and 3 departments of the outer picture peg of yaw pull rod 1 are equipped with spacing bolt spare 4.

Referring to fig. 1 and 2, the end of the swing rod 1 is inserted into the shaft end of the nail abutting seat assembly 2, and the end of the swing rod 1 is provided with an outer insertion plate 3, and the outer insertion plate 3 is attached to the outer wall of the shaft end of the nail abutting seat assembly 2.
