[0023] Trigger block 52 moves in trajectory housing 51 through a section of movement trajectory slide rail (not marked in the drawing), and the trajectory slide rail can also stably install trigger block 52 in trajectory housing 51;
[0024] The setting and installation mode of trajectory slide rail are determined by the movement direction of trigger block 52 in trajectory housing 51, and the determination of the movement direction is as follows:
[0025] The lower end of the trigger block 52 is provided with an inclined surface (not marked in the drawing), and the connection between the trajectory housing 51 and the trigger block 52 is provided with an inclined surface (not marked in the drawing);
[0026] Trigger block 52 moves with trajectory housing 51 through the inclined surface, and the movement trajectory of trigger block 52 is a section of inclined groove connected with a section of inclined surface and then connected with a section of straight groove, trigger block 52 moves downward first and then moves along the inclined surface, and then moves along the straight surface;
[0027] The anti-deviation component 6 comprises a receiving shell 61, and a main sliding plate 62 is slidingly installed in the receiving shell 61;
[0028] The main sliding plate 62 slides in the receiving shell 61, and the movement direction of the main sliding plate 62 is opposite to the sliding direction of the trigger block 52, and the connection position of the receiving shell 61 and the main sliding plate 62 is also provided with a track sliding rail, and the track sliding rail is defined as a straight line, so that the main sliding plate 62 only moves linearly on the receiving shell 61;
[0029] The main sliding plate 62 is provided with a hollow groove (not marked in the figure), the receiving shell 61 is provided with a fixing block 611, the fixing block 611 is installed in the hollow groove, and the fixing block 611 is provided with a limiting spring 63, and the limiting spring 63 is fixedly connected with the main sliding plate 62;
[0030] The main sliding plate 62 can slide in the receiving shell 61, and the movement distance of the main sliding plate 62 is limited, and the specific limitation is that the fixing block 611 is fixed, so that the main sliding plate 62 moves in the movement range defined by the hollow groove, and the limiting spring 63 provides structural strength for the structure, and can also make the main sliding plate 62 rebound quickly after work is completed, and restore the state before work;
[0031] The main sliding plate 62 is provided with a blocking block 621, and the trigger block 52 is provided with a clamping groove 521 at the front end;
[0032] The blocking block 621 is installed at the middle end of the main sliding plate 62, and the specific function is that the blocking block 621 abuts against the front end top surface of the trigger block 52, when the main sliding plate 62 moves, the blocking block 621 moves with it, the trigger block 52 enters the gap groove (not marked in the figure) formed between the blocking block 621 and the main sliding plate 62, and the blocking block 621 is clamped into the clamping groove 521, so that the trigger block 52 moves along the blocking block 621;
[0033] The receiving shell 61 is provided with an inclined surface at the front end, and the track shell 51 is provided with an inclined surface at the front end;
[0034] The inclined surface on the receiving shell 61 can abut against the inclined surface on the track shell 51, when the threaded control shaft 4 controls the movable clamping plate 2 to move close to the fixed clamping plate 3, the trigger component 5 also moves close to the anti-deviation component 6, that is, the track shell 51 abuts against the receiving shell 61, and the two groups of anti-deviation components 6 are pressed and close to each other by the action of the inclined surface, and the workpiece is clamped;
[0035] The main sliding plate 62 is provided with an abutting head 622;
[0036] The abutting head 622 is the first part to contact the side surface of the workpiece. When the abutting head 622 contacts the side surface of the workpiece, the main slide plate 62 slides in the receiving shell 61 due to the action of the limiting spring 63 until the abutting head 622 is retracted into the receiving shell 61. The blocking block 621 moves accordingly, so that the trigger block 52 enters the gap slot formed between the blocking block 621 and the main slide plate 62 (not shown in the figure), until the blocking block 621 is clamped into the clamping groove 521, so that the trigger block 52 moves along the blocking block 621;

[0040] The telescopic tight force push plate is installed at the center of the two groups of trigger components 5 and moves with the movable clamping plate 2. When it abuts against the side of the workpiece and pushes the workpiece forward, the telescopic tight force push plate retracts after the other side of the workpiece abuts against the surface of the fixed clamping plate 3. The specific working principle of the telescopic tight force push plate is the prior art, which will not be described here.
[0041] In summary, the operator controls the movable clamping plate 2 to approach the fixed clamping plate 3 by rotating the threaded control shaft 4, so that the trigger component 5 also approaches the anti-deviation component 6, that is, the track shell 51 abuts against the receiving shell 61. Through the inclined surface, the track shell 51 extrudes the two groups of receiving shells 61 to approach the center, the abutting head 622 contacts the side surface of the workpiece, and the main slide plate 62 slides in the receiving shell 61 due to the action of the limiting spring 63 until the abutting head 622 is retracted into the receiving shell 61. The blocking block 621 moves accordingly, so that the trigger block 52 enters the gap slot formed between the blocking block 621 and the main slide plate 62 (not shown in the figure), until the blocking block 621 is clamped into the clamping groove 521, so that the trigger block 52 moves along the blocking block 621. When the blocking block 621 blocks the top end of the trigger block 52, the trigger block 52 moves in the track shell 51 along the abutting surface direction. When the trigger block 52 enters the gap slot, the spring makes the trigger block 52 return to the original state and move in the gap slot in the main slide plate 62 until the two groups of receiving shells 61 abut against the outer side of the workpiece. The outer two side edges are clamped by the fixed clamping plate 3 and the telescopic tight force push plate, so as to realize the effect of providing secondary deviation prevention when the trigger component 5 and the anti-deviation component 6 cooperate to move during the use of the vise in the machining of the workpiece.
