Provided with fixed cover, two action bars are symmetrically installed with the lateral wall of the fixed cover, it is symmetrical on the madial wall of the fixed cover
Two fixture block grooves are offered, hairspring, two thin bullets are mounted in the side wall of the opposite side of two fixture block grooves
The relative one end of spring is respectively connected with wedge-shaped fixture block, is respectively connected with drawstring in the side wall of two wedge-shaped fixture block opposite side, and two
The individual drawstring through fixed cover and extends to the outside of fixed cover, and two one end of the drawstring away from wedge-shaped fixture block are common
It is connected with pulling block.
Preferably, symmetrically offer multiple necks on the lateral wall of the slotting axle, and each neck with wedge-shaped fixture block phase
Mutually coordinate.
Preferably, the internal symmetry of the fixed cover offers two transporting rooms, is mounted in two transporting rooms
Abutment extending, two drawstrings are transferred by abutment extending in transporting room.
Preferably, the lozenges of two wedge-shaped fixture blocks is respectively positioned on hairspring towards sandbox, two drawstrings
In cavity.
Preferably, heat-insulating shield is equipped with the side wall of two bearing plate opposite sides, and heat-insulating shield uses calcium silicates
Material is made.
Preferably, anti-slip veins are offered on the lateral wall of two action bars.
In the present invention, hookup is connected by user with arbor, by action bars firmly by fixed cover to hookup direction
Promote, because the lozenges of wedge-shaped fixture block is towards sandbox, therefore fixed cover can move always, be unclamped after pretightning force is adjusted
Action bars, the flat face gear of wedge-shaped fixture block make fixed cover not to be shot back on neck, pull pulling block, two drawstrings are by two wedges
Shape fixture block pulls out out of neck, you can unclamps preloading spring.The present invention is simple in construction, easy to operation, and traditional nut is fixed
Mode is changed to the mode fixed using fixture block, and fixed effect is more excellent, will not loosen preloading spring because of vibrations, while conveniently
Dismounting, it is efficiently convenient.
