Detailed Description
As shown in fig. 1-3, the first embodiment of the adjustable clamping mechanism of the present invention includes a fixing base 1, a handle 2, a clamping block 3, a connecting rod 4, a limiting member 5, an adjusting screw 6, a return spring 7, and a safety cover 8.
The middle part of clamp splice 3 articulate in fixing base 1 middle part, the outer end of clamp splice 3 is arc and fixing base 1 outer end is relative, form the centre gripping position between the outer end of clamp splice 3 and fixing base 1 outer end, the inner of clamp splice 3 and the one end spiro union of adjusting screw 6, the other end spiro union of adjusting screw 6 is at the middle part of connecting rod 4, the outer end of connecting rod 4 articulates on fixing base 1, the inner of connecting rod 4 is articulated with the middle part of handle 2, the outer end of handle 2 stretches out outwards, the inner of handle 2 articulates the one end at locating part 5, the other end of locating part 5 articulates in fixing base 1's slotted hole 11 and the convex shoulder 51 of one side of locating part 5 supports with fixing base 1 and leans on, play the effect of restriction. The reset spring 7 is arranged between the middle part of the clamping block 3 and the fixed seat 1.
The safety cover 8 covers the outer sides of the handle 2, the clamping block 3, the connecting rod 4 and the limiting piece 5.
The utility model discloses a theory of operation:
the handle 2 is pressed downwards, the handle 2 swings around the fixed seat 1 through the limiting piece 5, and meanwhile the connecting rod 4 drives the clamping block 3 to swing towards the direction of the fixed seat 1 to clamp a workpiece; when the handle 2 is released, the clamping block 3 is pushed by the elastic force of the return spring 7 to return.
As shown in fig. 4-7, a second embodiment of the adjustable clamping mechanism of the present invention includes a fixing base 1 ', a handle 2', a clamping block 3 ', a connecting rod 4', a limiting member 5 ', an adjusting screw 6', a return spring 7 ', and a connecting base 8'.
