When the fixture 2 and the guide rail 3 move toward the fixture, the pliers body 1 can be clamped onto any irregularly shaped fixture through the cooperation of the adjusting components.
[0044] Example 2:
[0045] like Figures 2-5 As shown, the quick-clamping pliers disclosed in Embodiment 2 of this utility model have a structure that is basically the same as that in Embodiment 1, except that:
[0046] The fixing rod 4 is provided in two sets, and the two sets of fixing rod 4 are symmetrically distributed with the adjusting screw 5 as the center.
[0047] The ends of the two sets of fixing rods 4 that are away from the fixing device 2 slide through the guide rail 3;
[0048] The adjustment component includes a recessed groove 6 formed on one side wall of the fixture 2 and the guide rail 3 that are close to each other. Multiple sets of recessed grooves 6 are formed and the multiple sets of recessed grooves 6 are evenly spaced.
[0049] Each of the sinking tanks 6 is equipped with a matching clamping rod 7 inserted inside. A matching second return spring 17 is provided between one end of each clamping rod 7 and the corresponding inner sidewall of the sinking tank 6. The clamping rod 7 is elastically inserted into the sinking tank 6 through the second return spring 17.
[0050] Each of the clamping rods 7 has a first through hole 9 on its upper end face. The first through hole 9 penetrates the clamping rod 7, and multiple sets of the first through holes 9 are provided, with the multiple sets of the first through holes 9 evenly spaced apart.
[0051] Each of the first through holes 9 is fitted with a matching first abutment rod 8. Each of the first through holes 9 has a guide groove 21 at the position of the first abutment rod 8 on its inner sidewall. A matching guide rod 20 is slidably fitted inside the guide groove 21. The guide rod 20 is connected to the first abutment rod 8.
[0052] A third return spring 22 is provided inside the guide groove 21, and the two ends of the third return spring 22 are respectively connected to the side wall of the guide rod 20 and the bottom of the guide groove 21;
[0053] A fourth through hole 18 is provided between two adjacent sets of settling tanks 6, and the two adjacent sets of settling tanks 6 are interconnected through the fourth through hole 18;
[0054] The size of the fourth through hole 18 matches the size of the first through hole 9, and a matching third abutment rod 19 is slidably disposed inside the fourth through hole 18. The size of the third abutment rod 19 matches the size of the first abutment rod 8.
[0055] The fixture 2 and the guide rail 3 are provided with a clearance groove 12 at the position of the uppermost recess 6. A matching pressure plate 13 is slidably arranged inside the clearance groove 12. A first return spring 14 is provided between the lower end face of the pressure plate 13 and the bottom of the clearance groove 12. Multiple sets of the first return spring 14 are provided and the multiple sets of the first return spring 14 are evenly spaced.
[0056] The bottom of the relief groove 12 is provided with a third through hole 15 at the position of each uppermost sink 6. A matching second abutment rod 16 is slidably disposed inside the third through hole 15. One end of the second abutment rod 16 passes through the third through hole 15 and is connected to the lower end face of the pressure plate 13.
[0057] The top of the recessed groove 12 is provided with a second through hole 11, which passes through the fixture 2 and the guide rail 3, and a matching pull rod 10 is inserted into the inside of the second through hole 11.
[0058] By adjusting the rotation of the screw 5, the guide rail 3 moves toward the fixture 2. Through the cooperation of the fixture 2 and the guide rail 3, the fixture is clamped by the fixture 2 and the guide rail 3, thereby fixing the pliers body 1 in the designated position. When the fixture 2 and the guide rail 3 move toward the fixture, they will squeeze the elastically set clamping rods 7, causing the clamping rods 7 to retract into the interior of the recess 6. When all the elastically set clamping rods 7 are in contact with the fixture, the pull rod 10 is pressed down. The pull rod 10 presses down each of the second abutment rods 16 through the pressure plate 13. The second abutment rods 16 then press down the first abutment rod 8 on the corresponding clamping rod 7. The first abutment rod 8 then presses down the first abutment rod 8 on the adjacent clamping rod 7 through the third abutment rod 19, thereby limiting the position of each elastically set clamping rod 7 and fixing the pliers body 1 to the irregular fixture through each clamping rod 7.
[0059] Example 3:
[0060] like Figures 6-7 As shown, the quick-clamping pliers disclosed in Embodiment 3 of this utility model have a structure that is basically the same as that in Embodiment 2, except that:
[0061] A limiting groove 23 is formed on the inner sidewall of the second through hole 11. The cross-section of the limiting groove 23 is "L" shaped, and a matching limiting block 24 is slidably arranged inside the limiting groove 23. The limiting block 24 is fixedly arranged on the outer surface of the pull rod 10.
[0062] When the pull rod 10 is pressed down, the limiting block 24 will move downward along the vertical groove of the limiting groove 23. When it moves to the bottom of the vertical groove of the limiting groove 23, the pull rod 10 is rotated. At this time, the limiting block 24 will rotate along the horizontal groove of the limiting groove 23. Through the cooperation of the horizontal groove of the limiting groove 23, the pull rod 10 is limited.
[0063] The specific solution is as follows: The vibratory pliers body 1 clamps the workpiece. Then, the retainer 2 and guide rail 3 are placed on both sides of the fixed part. Next, the adjusting screw 5 is rotated. The rotation of the adjusting screw 5 causes the guide rail 3 to move towards the retainer 2. Through the cooperation of the retainer 2 and guide rail 3, the fixed part is clamped by the retainer 2 and guide rail 3, thus fixing the vibratory pliers body 1 in the designated position. Furthermore, as the retainer 2 and guide rail 3 move towards the fixed part, they compress the elastically set clamping rod 7, causing the clamping rod... 7 retracts into the interior of the sink 6. When all the elastically set clamping rods 7 are in contact with the fixing parts, the pull rod 10 is pressed down. The pull rod 10 presses down each of the second abutting rods 16 through the pressure plate 13. The second abutting rods 16 then press down the first abutting rod 8 on the corresponding clamping rod 7. The first abutting rod 8 then presses down the first abutting rod 8 on the adjacent clamping rod 7 through the third abutting rod 19, thereby limiting the clamping rods 7 and fixing the clamping pliers body 1 to the irregular fixing parts through each clamping rod 7.
[0064] At the same time, when the pull rod 10 is pressed down, the limiting block 24 will move downward along the vertical groove of the limiting groove 23. When it moves to the bottom of the vertical groove of the limiting groove 23, the pull rod 10 is rotated. At this time, the limiting block 24 will rotate along the horizontal groove of the limiting groove 23. Through the cooperation of the horizontal groove of the limiting groove 23, the pull rod 10 is limited.
[0065] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.
[0066] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
