Gland be bolted to by same group on housing, the upper end of described rotating shaft is inserted in the axis hole on gear guard, rotating shaft
Lower end be inserted in the blind hole on gland, the upper end of rotating shaft is machined with spanner clamping section；
Spring pivot bracket is fixedly installed on described gear guard, vertical latch is installed on spring pivot bracket, is inserted
Sell the movement tendency that keeps down under the action of the spring, the face of cylinder and the cylinder on the inside of gear guard on the outside of described rotary body
Face is a pair of dimensional fits faces, and the outward flange of rotary body is provided with gap A, and the inward flange of gear guard is provided with gap B, gap
A and gap B splits form pin-and-hole corresponding with described latch.
The axis of described pin-and-hole is in the dimensional fits face between rotary body and gear guard.Described gap A is extremely
Rare two, each gap A is uniformly distributed around the axle center of rotary body.
The beneficial effects of the utility model are：
1st, the utility model uses latch structure, and the junction for being located at rotary body and gear guard of latch, by latch
Insert pin-and-hole in after, latch can play with the key identical effect in key connection structure, therefore, the utility model have knot
The advantages that structure is simple, rapid operation, strong torque resistant ability.
2nd, gear drive is provided with the utility model, is rotated by spanner driving pinion, gear wheel can be driven
Rotation, so as to realize the driving to rotary body, compared with the mode rotated in the prior art with pipe wrench, pipe wrench is avoided to oil pipe
Or the damage of other parts, while operate more laborsaving.
3rd, gap A at least two, each gap A are uniformly distributed around the axle center of rotary body, and such set causes operation
In rotary body can be locked according to different operating modes by different positions.
