Furthermore, rib plates are arranged between the fixing plate and the base and between the clamping plate and the base.
Furthermore, one side of the fixing plate, which is close to the clamping plate, is provided with two check blocks, one check block is positioned on one side of the bottom of the cross hole, and the other check block is positioned on the other side of the top of the cross hole.
Furthermore, a base plate is arranged on one side, close to the fixing plate, of the clamping plate.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a set up the screw rod and the nut spiro union of end connection clamp splice, can adjust the position of clamp splice, make its and fixed splint cooperation press from both sides tight work piece, can realize pressing from both sides the dress to the work piece, and carry out the clamping to same batch work piece and add man-hour, can adjust the clamp splice position through removing the nut, need not rotate screw rod adjustment clamp splice, labour saving and time saving more has reached quick clamping's effect.

in the figure: 1. the clamp comprises a base, 2, a fixing plate, 21, a cross hole, 3, a clamping plate, 4, a rib plate, 5, a nut, 51, a circular boss, 52, a handle, 53, a cross boss, 6, a screw, 7, a clamping block, 8, a connecting hole, 9, a stop block, 10 and a cushion block.
Detailed Description
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
As shown in fig. 1 to 3, the embodiment of the present invention comprises a base 1 and a nut 5, wherein a fixing plate 2 is arranged at one end of the top of the base 1, and a clamping plate 3 is arranged at the other end; connecting holes 8 are formed in four included angles of the base 1, a cross hole 21 is formed in the middle of the fixing plate 2, a round boss 51 is arranged at one end of the nut 5, a cross boss 53 is arranged at the other end of the nut, and the round boss 51 and the cross boss 53 are respectively located on two sides of the fixing plate 2; the shape of the cross boss 53 is the same as the inner shape of the cross hole 21, and the diameter of the round boss 51 is larger than the aperture of the cross hole 21; a plurality of handles 52 are uniformly connected to the round boss 51 along the circumferential direction; the nut 5 is connected with a screw rod 6 in a penetrating and screwed mode, and the end portion, close to the clamping plate 3, of the screw rod 6 is connected with a clamping block 7.
When a tower crane workpiece needs to be clamped, firstly, the workpiece is placed between the clamping block 7 and the clamping plate 3 according to the width of a workpiece clamping position, the fixing nut 5 is held by the handle 52, and then the screw 6 is rotated to adjust the position of the clamping block 7, so that the clamping block 7 and the clamping plate 3 clamp the workpiece; then clockwise rotation nut 5 makes cross boss 53 rotate 90, and one side that fixed plate 2 is close to splint 3 is equipped with dog 9, the quantity of dog 9 is two, and a dog 9 is located cross hole 21 bottom one side, and another dog 9 is located cross hole 21 top opposite side, and cross boss 53 both ends support two dog 9 respectively, and cross boss 53 can no longer pass through cross hole 21, and then deadly locks nut 5, so can quick clamping work piece.
And if add man-hour to same batch's work piece, can anticlockwise rotate 90 with nut 5 for cross boss 53 corresponds with cross hole 21, remove nut 5 toward the direction of keeping away from splint 3 after that, can loosen the work piece, when next work piece clamping, remove nut 5 toward the direction of being close to splint 3 again, make clamp splice 7 and splint 3 clip the work piece once more can, saved the time of rotating 6 adjustment clamp splices 7 of screw rod, labour saving and time saving more.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
