All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

The application relates to a hinged clamp holder, this clamp holder is including being used for playing the lower base 1 of basic supporting role and with the articulated last base 2 of one end looks of lower base 1 as shown in fig. 1-6, in order to save the cost of manufacture, go up base 2 and lower base 1 and all can adopt square steel pipe preparation, it is provided with the screw rod 4 that can adjust interval and be used for the centre gripping work piece to go up base 2 upper portion one end, it is provided with the blend stop 7 that cooperates with screw rod 4 and play auxiliary gripping work piece to go up base 2 upper portion other end, blend stop 7 also can adopt square steel pipe preparation, still be provided with the lifting unit who is used for adjusting contained angle between the two in order to change the work piece centre gripping back orientation between upper base 2 and the lower base 1.

The lifting assembly is a sleeper block 9, the sleeper block 9 can be made of square steel pipes, in order to increase stability of the upper base 2 after lifting, the position, where the sleeper block 9 is in contact with the upper base 2, is subjected to round corner treatment so as to effectively disperse pressure from the upper base 2, and the sleeper block 9 is placed at a proper position between the upper base 2 and the lower base 1 according to the angle of the upper base 2 and the lower base 1, wherein the placing mode is shown in fig. 4-6.

The two sides of the lower base 1 are provided with side plates 8 fixedly connected with the lower base 1, the upper side of the side plates 8 is used for being connected with an upper base 2 hinged with the side plates, in order to avoid motion interference with the lower base 1 when the upper base 2 rotates around the side plates 8, the end part of the lower surface of the upper base 2, which is contacted with the lower base 1, is subjected to chamfering treatment, and the size of the chamfering is determined according to the motion interference range.

One end of the upper base 2, on which the screw 4 is placed, is provided with a nut 5 which is in threaded connection with the screw and is used for supporting and guiding the screw, a pressing plate 6 which can enlarge the contact area between the screw 4 and the workpiece is additionally arranged at one end of the screw 4, and a hand wheel 3 which is convenient for a user to rotate is additionally arranged at the other end of the screw 4, so that the user can rotate the screw 4 in a labor-saving manner.

Example 2

In this embodiment, as shown in fig. 7-9, since the pillow 9 is placed separately and is easy to be lost, and is easy to shift due to shaking (which means that polishing or drilling operation is usually performed after the workpiece is fixed, and the lower base 1 and the upper base 2 vibrate together at the moment, and the pillow 9 vibrates and slides easily), so that the angle adjustment fails, the lifting assembly is improved, and the fixing pins 10 are symmetrically arranged on two sides of the lower base 1, the movable pins 12 capable of screwing in and out are symmetrically arranged on two sides of the upper base 2, then a connecting piece 11 for connecting is additionally arranged between the fixing pins 10 and the movable pins 12, one end of the connecting piece 11 rotates around the fixing pins 10, and the other end of the connecting piece 11 is provided with a notch 13 capable of sliding along the movable pins 12;

when the included angle between the upper base 2 and the lower base 1 is required to be adjusted, the movable pin 12 is screwed out, then the upper base 2 is turned upwards, the upper base 2 is turned around the position hinged with the side plate 8, the movable pin 12 slides in the notch 13 and drives the connecting piece 11 to rotate, after the rotation is finished, the movable pin 12 is screwed in, the connecting piece 11 is locked by the movable pin 12, at the moment, the angle between the upper base 2 and the lower base 1 is finished, and at the moment, the suspension support at one end of the upper base 2 is provided by means of the pressure (namely friction force) between the movable pin 12 and the connecting piece 11;

of course, if the compressive strength between the upper base 2 and the lower base 1 after being turned over is further enhanced to avoid failure of the connecting member 11, the pillow 9 may be placed between the upper base 2 and the lower base 1 for further protection.
