The top of the push card holder has a slot corresponding to the through hole on the surface of the locking plate for the bolt to pass through and lock.

[0010] This utility model provides a flat-jaw pliers heightening block splicing assembly, which has the following beneficial effects:

[0011] 1. A flat-jaw pliers extension block splicing assembly, comprising a rotating extension block with a snap-fit ​​structure. One end of the rotating extension block with an access slot is inserted into a pre-set limiting slot on the surface of a push base and a positioning plate. The rotating extension block surrounds the outside of the push base and the positioning plate, at which point the mating slot and the mounting slot correspond. A fixing bolt is passed through the mounting slot and the mating slot and rotated to lock the rotating extension block in place. An adjusting shaft is inserted through a connecting screw hole into a threaded cylinder on the surface of the push base. During the rotation of the adjusting shaft, the push base moves towards the positioning plate, securing the workpiece between the push base and the positioning plate. The long plate portion of the rotating extension block is available in various specifications to suit different workpiece sizes. The rotating extension block is also very easy to disassemble and replace, greatly improving the applicability of the device.

[0012] 2. A flat-jaw pliers extension block splicing assembly, featuring a modular push-type mounting base. When the push-type mounting base is inserted into the control cavity, it can move freely up and down. After the alternating extension block is mounted and locked in the limiting slot on the front side of the push-type mounting base, a locking plate is inserted between two locking slots. At this point, the bottom of the push-type mounting base is precisely inserted into a pre-set slot on the surface of the locking plate. Through holes and threaded grooves for docking and restriction are pre-drilled on the top of the locking plate and the bottom of the push-type mounting base, respectively. A bolt is passed through the outside of the locking plate and into the pre-drilled threaded groove on the bottom of the push-type mounting base, and rotated to lock and restrict the position of the entire push-type mounting base. Restricted by the alternating extension block and the locking plate, the push-type mounting base can only move laterally within the control cavity. Rotating the adjusting shaft to move the push-type mounting base is more stable, and the modular push-type mounting base is very convenient to install. Attached Figure Description

[0019] A type of flat-jaw pliers extension block splicing assembly, such as Figures 1 to 3 As shown, the device includes a mounting base 1, an adjustment cavity 2 inside the mounting base 1, positioning plates 3 fixedly mounted on both sides of the outer side of the mounting base 1, and openings for bolts to pass through inside the positioning plates 3. A connecting screw hole 4 is opened at the center of the front surface of the mounting base 1, and an adjustment shaft 5 is inserted into the connecting screw hole 4. A push bracket 7 is inserted into the adjustment cavity 2, and the length of the push bracket 7 is less than the internal depth of the adjustment cavity 2. A threaded cylinder for the front end of the adjustment shaft 5 is opened on the side surface of the push bracket 7 near the connecting screw hole 4. A positioning plate 8 is fixedly mounted on the rear surface of the mounting base 1. Rotating heightening blocks 9 for clamping workpieces are opened on the side surfaces of the push bracket 7 and the positioning plate 8 that are close to each other.

[0020] The bottom of the rotating height-increasing block 9 has a folded corner structure, and the lateral length of the rotating height-increasing block 9 is greater than the lateral length of the push card seat 7 and the positioning card plate 8. The lower surface of the rotating height-increasing block 9 is provided with an access slot 10. The side surfaces of the push card seat 7 and the positioning card plate 8 that are close to each other are provided with a limit slot 12. The lower end of the rotating height-increasing block 9 is inserted into the corresponding limit slot 12 and locked in place. After the rotating height-increasing block 9 is locked in place, the folded corner end surrounds the two sides of the push card seat 7 so that the entire rotating height-increasing block 9 will not wobble from side to side after installation.

[0021] The top surfaces of the push card holder 7 and the positioning card plate 8 are both provided with mounting holes 13 that connect to the inside of the limiting slot 12. The surface of the access slot 10 is provided with mating holes 11 that are far apart from each other. After the rotating heightening block 9 is installed inside the limiting slot 12, the mating holes 11 and the mounting holes 13 are aligned. By inserting a fixing bolt into the mounting hole 13 and rotating it into the mating hole 11 to lock it, the rotating heightening block 9 is completely installed on the outside of the push card holder 7 and the positioning card plate 8.

[0022] The lower end surface of the control cavity 2 is provided with a snap-fit ​​groove 6, and a locking plate 14 is snapped into the inside of the snap-fit ​​groove 6. The surface of the locking plate 14 is pre-set with a slot corresponding to the size of the bottom of the push base 7.

[0023] After the push bracket 7 is inserted into the control cavity 2, its bottom is inserted into the slot on the surface of the locking plate 14. The top of the push bracket 7 has a slot corresponding to the through hole on the surface of the locking plate 14 for the bolt to pass through and lock. The push bracket 7 is restricted to be installed inside the control cavity 2 by the locking plate 14. When the rotating adjustment shaft 5 presses against the threaded cylinder on the surface of the push bracket 7, it can drive the push bracket 7 to move laterally to clamp and fix the workpiece.

[0024] The working principle of this utility model:

[0025] By inserting one end of the rotating height-increasing block 9 with the access slot 10 into the preset limiting slot 12 on the surface of the push base 7 and the positioning plate 8, the rotating height-increasing block 9 surrounds the outside of the push base 7 and the positioning plate 8. At this time, the docking slot 11 and the fixed installation slot 13 are in corresponding positions. After the fixing bolt is passed through the inside of the fixed installation slot 13 and the docking slot 11 and rotated to lock, the installation of the rotating height-increasing block 9 is completed. After the adjusting shaft 5 is inserted into the threaded cylinder on the surface of the push base 7 through the connecting screw hole 4, the push base 7 moves towards the positioning plate 8 during the rotation of the adjusting shaft 5. The workpiece to be fixed is inserted between the push base 7 and the positioning plate 8 for fixation. The long plate part of the rotating height-increasing block 9 is equipped with various specifications that can be selected according to the size of the workpiece. The rotating height-increasing block 9 is also very simple to disassemble and replace, which greatly improves the applicability of the device.

[0026] The push-mounted bracket 7, with its modular structure, can move freely up and down when inserted into the control cavity 2. After the rotating heightening block 9 is inserted into the limiting slot 12 on the front side of the push-mounted bracket 7 and locked, the locking plate 14 is inserted between the two locking slots 6. At this time, the bottom of the push-mounted bracket 7 is inserted into the pre-set slot on the surface of the locking plate 14. The top of the locking plate 14 and the bottom of the push-mounted bracket 7 are respectively reserved with through holes and threaded grooves for docking restriction. After the bolt is inserted through the outside of the locking plate 14 into the pre-reserved threaded groove at the bottom of the push-mounted bracket 7 and rotated to lock, the position of the entire push-mounted bracket 7 is restricted. After being restricted by the rotating heightening block 9 and the locking plate 14, the push-mounted bracket 7 can only move laterally inside the control cavity 2. The rotation adjustment shaft 5 makes the movement of the push-mounted bracket 7 more stable. The modular structure of the push-mounted bracket 7 is also very convenient to install.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
