Again, gripper shoe described in the utility model is L-shaped.

The beneficial effects of the utility model

The utility model is by cooperations such as Design Orientation pin, limiting plates, realizes the location and from locking, and is less for weight, surface condition is complicated, workpiece in irregular shape, can design different anchor clamps and be connected with manual turning device; Practicality, flexibility are strong, and manually control is easy to operate simple.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the side view of Fig. 1;

Fig. 3 is a user mode schematic diagram of the present utility model.

The specific embodiment

Referring to Fig. 1～Fig. 3, manual upset self-locking device of the present utility model connects with upset hook mechanism 9 mutually by bearing pin or connecting rod, drives upset hook mechanism 9 and implements upset; Comprise fixed bar 1, spanner 2, alignment pin 3, spring 4, adjustable plate 5, screw 6, limiting plate 7, gripper shoe 8, upset hook mechanism 9;

Fixed bar 1, lower end are fixed a stationary pipes 11, these stationary pipes 11 1 end openings 111, and its upper surface has through hole 112; Described fixed bar 1 has holddown groove 13 along its length, also fixes a fixed block 14 on these holddown groove 13 inwalls;

Spanner 2 is movably connected on the fixed bar 1, and is L-shaped, one end 21 corresponding stationary pipes 1 through holes 12, and this spanner 2 is arranged in fixed bar 1 holddown groove 13, and spanner 2 one ends and fixed block 14 flexibly connect by a bearing pin 15;

Alignment pin 3 is inserted in fixed bar 1 stationary pipes 11, and its body 30 is radially offered positioning through hole 301, and the end formation one of alignment pin 3 is step 31 fixedly, and step 31 1 sides are also established a guide pillar 32; The end that alignment pin 3 is positioned at stationary pipes 11 is a fixed leg 32 also, these fixed leg 32 sheathed springs 4; Spring 4 other ends are against an adjustable plate 5, and this adjustable plate 5 is connected in screw 6 one ends of stationary pipes 11 other ends;
