Preferably, the round table end of the pull rod is clamped with the protective gland. The protection gland of this scheme plays the effect of sheltering from pull rod and main part extrusion position, prevents in staff's gloves, clothing etc. squeeze into the main part, has improved the security of production.
Preferably, the base is provided with a screw hole, one side of the periphery of the main body, which is close to the base, is provided with an edge, the edge is provided with a through hole, a bolt is arranged in the through hole, the bolt penetrates through the through hole and is inserted into the screw hole for threaded fit, namely, the base is fixedly connected with the main body through the bolt. The connecting strength of the base and the main body is guaranteed due to the fact that the bolts are fixedly connected, when the main body with different sizes needs to be replaced, the main body can be detached by unscrewing the bolts, the mounting and dismounting are convenient and fast, and the mounting and dismounting efficiency of the main body is improved.
Preferably, four bolts are arranged and distributed on the periphery of the main body respectively. Through the bolt-up base and the main part that distribute all around, can be around the base with the power dispersion that the main part received, the main part atress is more even, makes the utility model discloses an anchor clamps structure is more stable.
The utility model has the advantages that: the utility model discloses to rise the cover integration in the main part, the cover that rises and main part design structure as an organic whole can prevent that the cover that rises from following the blank and reciprocating, avoids blank offset, makes the blank clamping more firm, has improved the machining precision of outer gear shaping, has optimized the quality of outer gear, has satisfied the operation requirement of outer gear finished product in actual production.
