Second locking knob coordinates with threaded one end of second screw rod away from transition bracket, and the second locking knob is used to make Transition bracket is strained and fixed with base body.

As illustrated in figs. 3 and 10, in this present embodiment, base body 7 has the 4th scale 50 that arc is set, the 4th scale 50 is corresponding with the second adjustment hole 47.There is the 4th instruction structure 51, the 4th instruction structure 51 and the 4th scale on transition bracket 8 50 cooperations, for determining the position of transition bracket 8.

As shown in figure 9, the elasticity for being also equipped with resetting grinding mechanism 3 between transition bracket 8 and grinding mechanism 3 is answered Position part 84.Dynamic clamping head and quiet clamping head 84 can be torsional spring.

As shown in Figures 9 and 10, in this present embodiment, one end of base body 7 has vertical portion 9, and transition bracket 8 rotates peace On vertical portion 9.By setting vertical portion 9 that can facilitate the installation of transition bracket 8.

As shown in figs. 1 and 6, clamp system 2 further includes positioning component 6, and positioning component 6 includes：

Locating rack 75 is rotatably installed in fixed seat 86；

Screw rod is installed, is threaded through on locating rack 75, the bar portion 71 for installing screw rod is pierced by locating rack 75, installs the nut of screw rod Portion 76 and locating rack 75 against；

Locating rod 73 is set in bar portion 71, positioned at the top of two tablettings, for being positioned to workpiece to be ground；

Elastic element 74 is arranged between locating rod 73 and locating rack 75, for locating rod 73 to be made to have remotely located frame 75 movement tendency；

Stop nut 72 is screwed onto bar portion 71,72 end of stop nut and locating rod 73 against stop nut 72 and elasticity Element 74 is located at 73 both sides of locating rod, for limiting axial position of the locating rod 73 on installation screw rod.

The axial position of locating rod 73 can be limited by stop nut 72 and elastic element 74.It is fixed when needing to adjust During 73 position of bar of position, it is only necessary to which rotary stopper nut 72, locating rod 73 can be adjusted automatically under the action of elastic element 74 On section to new position.The positioning component 6 of the application can quickly adjust the axial position of locating rod 73.

Workpiece to be ground described in the application refers to the workpiece that chain etc. is positioned.

In this present embodiment, elastic element 74 is the spring for being set in bar portion 71.

As shown in fig. 6, in this present embodiment, positioning component 6 further includes：

Adjusting bolt 70 is threaded in fixed seat 86；

Reduction torsion spring 69 is arranged on the place that is rotatably assorted of locating rack 75 and fixed seat 86, for making the side wall of locating rack 75 With the end of adjusting bolt 70 against.

The above is only the preferred embodiment of the present invention, not thereby limits the patent protection of the utility model Scope, every equivalent structure transformation made with the utility model specification and accompanying drawing content, is directly or indirectly used in it His relevant technical field similarly includes within the protection scope of the present utility model.
