The moving mechanism comprises a rail and a roller arranged at the bottom of the workbench 1, a worker can place a part on the workbench 1 and adjust the position of the part when processing, and then the worker can push the workbench 1 to move on the rail when pressing the part on the surface of the workbench 1 by hand, so that the part can be processed.

As shown in fig. 2 and 3, a mounting base 2 is vertically slidably connected to a table 1, a beam 3 is fixed to the mounting base 2, one end of the beam 3 extends toward the center of the table 1, a pressing member 4 is connected to an end of the beam, the pressing member 4 extends toward the surface of the table 1, an elastic pressing block 5 is fixed to the bottom of the pressing member 4, and in this embodiment, the elastic pressing block 5 is rubber. When the clamp is operated to clamp the part, the part is placed on the surface of the workbench 1, a worker applies force to press the cross beam 3 downwards, the mounting seat 2 slides downwards on the clamp, and in the sliding process, rubber on the pressing piece 4 is in contact with the surface of the part. When continuing to exert pressure, rubber produces elastic deformation and compresses tightly the part on workstation 1, be equipped with elasticity stop gear on mount pad 2 simultaneously, elasticity stop gear restriction mount pad 2 slides in workstation 1 back reverse roll-off workstation 1, so set up to make the part can be compressed tightly on workstation 1 by rubber, so the staff carries out the in-process that the worker advances to the part, no longer need carry out continuous exerting pressure to the part and make its restriction on workstation 1, reached and replaced artificial effect, make the possessing of part stabilize good tight effect of clamp.

Elasticity stop gear includes stopper 6 and elastic component 7, and wherein, stopper 6 and 2 horizontal sliding connection of mount pad are equipped with in mount pad 2 and accomodate groove 8, and elastic component 7 is the spring, and the one end of spring is fixed other end and mount pad 2 with stopper 6, and setting up of spring orders about stopper 6 under the effect of elastic force, slides to the one side of accomodating groove 8 for stopper 6's one end protrusion mount pad 2. When the limiting block 6 receives an external force which is opposite to the direction of the elastic force of the spring and larger than the elastic force value of the spring, the limiting block 6 slides into the accommodating groove 8 under the condition of overcoming the elastic force.

When a worker clamps a part, the part is placed on the surface of the workbench 1 in advance, and then the mounting seat 2 is installed into the workbench 1. The beam 3 is pressed downwards, and along with the downward sliding of the installation seat 2, the limiting block 6 which is protruded out of the installation seat 2 under the elastic force of the spring is contacted with the top surface of the workbench 1 to limit the continuous downward sliding of the installation seat 2. Press stopper 6, in the groove 8 is accomodate in pushing into stopper 6 under the circumstances of overcoming elasticity, stopper 6 slides in and accomodates the gliding of groove 8 back no longer restriction mount pad 2, continue to press crossbeam 3 downwards this moment, the in-process that mount pad 2 moved down, apply pressure piece 4 on the rubber will contact with the surface of part, when continuing to exert pressure to crossbeam 3, rubber will produce elastic deformation and compress tightly the part on workstation 1, stopper 6 slides to the bottom of workstation 1 this moment, and stopper 6 resets under the effect of spring force and protrudes the mount pad 2 outward.

Preferably, the bottom of the stopper 6 is provided with an inclined surface 14, and the inclined surface 14 is inclined from the highest side to the lowest side toward the elastic member 7. After workstation 1 is installed to mount pad 2, along with the gliding of mount pad 2, inclined plane 14 contacts with the top surface of workstation 1, when continuing to press and move mount pad 2 gliding, the top surface of workstation 1 will form the thrust of a perpendicular to inclined plane 14, and a component of thrust directly indicates to accomodate groove 8, so when mount pad 2 continues to move down, the top surface of workstation 1 will push up and drive stopper 6 to accomodate the inslot 8 to inclined plane 14 and remove, the staff need not manually promote stopper 6 and can push stopper 6 into accomodate the inslot 8, such setting has reduced manual operation's step, make the clamping process of anchor clamps more convenient.

the specific working process is as follows: when a worker clamps a part, the part is placed on the surface of the workbench 1 in advance, and then the mounting seat 2 is installed into the workbench 1. The force application rod is pressed downwards. Along with the gliding of mount pad 2, receive spring force and the stopper 6 of protrusion mount pad 2 will contact with the top surface of workstation 1, when mount pad 2 continues to move down, the top surface of workstation 1 will push up inclined plane 14 and drive stopper 6 and move to accommodating the groove 8, continues to press the application of force pole downwards, and the in-process that mount pad 2 moved down will contact with the surface of part with the rubber on the application of force spare 4. When continuing to exert pressure to the application of force pole, rubber will produce elastic deformation and compress tightly the part on workstation 1, and stopper 6 slides to the bottom of workstation 1 this moment, and stopper 6 resets under the effect of spring force outside protrusion mount pad 2. After the worker loosens his hands, the limiting block 6 limits the mounting seat 2 to move upwards, and the rubber which is elastically deformed continuously applies pressure to the part to be fixed, so that the effect of clamping the part is achieved.

when the part is dismantled to anchor clamps, utilize the spanner, go into hexagonal arch 12 with the spanner on, drive transmission shaft 10 with the help of the spanner afterwards and rotate, finally drive stopper 6 and slide into and accomodate the groove 8 in, the part no longer receives exerting pressure of rubber this moment, can take out mount pad 2.
