According to the arrangement, the load is applied, the rear connecting part rotates around the stud in the installation through groove, the deflection rod is driven to deflect around the stud, and meanwhile, the deflection rod can rotate relative to the upright column, so that the grinding plate is brought to a proper position.

As preferred correspond in the periphery of dwang the position that the logical groove below was led to in the installation is provided with a gag lever post respectively, this gag lever post with contained angle between the dwang is less than the degree, and is close to lapping plate one side the gag lever post with contained angle is greater than and is close to between the dwang load one side the gag lever post with contained angle between the dwang.

So set up, go the back on load and grinding plate connect, because the action of gravity, the one side that the deflection pole is close to the grinding plate supports on one of them spacing post, then after rotatory to suitable position, operating personnel has carried the grinding plate and has begun work, and the one side that the deflection pole is close to the load at this moment supports on another spacing post.

Preferably, the upper end of the limiting rod is provided with an arc-shaped groove, and the arc-shaped groove is matched with the deflection rod.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses can produce the deflection in rotatory, make staff's during operation more labour saving and time saving on the one hand, improve work efficiency, on the other hand makes the motion space of lapping plate more extensive, and operating personnel is also more convenient at the during operation. Meanwhile, the structure is simple, the cost is low, and the use is convenient.
