A boosting shaft 6 is threadedly installed in the threaded groove 33, and the boosting shaft 6 passes through the boosting groove 31. A push rod 61 is provided on the boosting shaft 6, and the push rod 61 is provided with an inclined cone surface which gradually becomes smaller toward the direction of the screw rod 2. The push rod 61 is matched with the boosting mechanism, and a driving head 62 is installed at the end of the boosting shaft 6 away from the push rod 61; the boosting shaft 6 and the transmission sleeve 3 are relatively fixed by an elastic mechanism.

[0027] The elastic mechanism includes a fixed spring 64 and a fixed steel ball 65. The boost shaft 6 is provided with a thickened section 63 and a threaded section 66. The outer diameter of the thickened section 63 is larger than the outer diameter of the threaded section 66. The threaded section 66 is threadedly installed with the thread groove 33. Mounting grooves 60 are provided on both sides of the thickened section 63. The two mounting grooves 60 are staggered in the axial direction of the thickened section 63. A fixed spring 64 is provided in the mounting groove 60. A fixed steel ball 65 is provided at the end of the fixed spring 64. A fixed through groove 34 matching the fixed steel ball 65 is provided on the transmission sleeve 3.

[0028] The boost mechanism includes a disc spring 8 and a retainer 9. A boost chute 91 is provided on the retainer 9. The inclination direction of the boost chute 91 is consistent with the oblique conical surface of the push rod 61. The boost chute 91 is opened on the side of the retainer 9 close to the push rod 61. A rolling body 92 is provided in the boost chute 91. A retainer 9 is provided on the side of the limit column 21 away from the screw rod 2. A disc spring 8 is provided on the side of the retainer 9 close to the push rod 61. A front gasket 81 is provided between the disc spring 8 and the retainer 9. The center of the retainer 9, the front gasket 81 and the disc spring 8 There are through holes for the push rod 61 to pass through, and the depth of the boosting chute 91 gradually decreases in the direction away from the push rod 61. Several boosting chute 91 are connected at the center of the retaining frame 9. A rolling body 92 is installed in each boosting chute 91. The rolling body 92 is a sphere. The bottom of the boosting chute 91 is an arc-shaped bottom edge that matches the sphere. One side of the sphere rolls and abuts against the arc-shaped bottom edge, and the other side rolls and abuts against the front gasket 81. When boosting, the inner side of the sphere rolls and abuts against the oblique conical surface of the push rod 61. A rear gasket 82 is provided between the limit gasket 4 and the retaining frame 9.

[0029] The curved inner wall of the boost chute 91 is in closer contact with the surface of the sphere. When the sphere rolls, it is inevitable that its posture will adjust due to the slight shaking of its own center of gravity. The curved surface of the arc bottom edge can buffer this adjustment through slight displacement of the contact point, ensuring the continuity of rolling and making the entire boost process smoother.

[0030] The contact between the sphere and the groove wall in the arc groove is point contact. The pressure at the contact point is naturally transferred as it rolls, and the curved surface of the arc groove can constrain the sphere through the "centripetal force effect". When the sphere tends to deviate laterally, the curved surface will generate a reaction force pointing to the center, pulling it back to a stable trajectory.

[0031] The support point position of the ball in the boost chute 91 changes naturally with rolling, the pressure distribution is uniform, and the rolling friction coefficient is more stable; the contact between the ball and the boost chute 91 is smoother, and rigid collision almost does not occur. The loss of kinetic energy converted into collision heat energy is extremely small, effectively reducing the friction loss between the ball and the boost chute.

[0032] There are three supercharging chute 91 , and the angle formed between the supercharging chute 91 is 120 degrees.

[0033] The pliers body 1 is provided with a receiving groove 17 , and the screw rod 2 is arranged in the receiving groove 17 . Both sides of the bottom of the receiving groove 17 are provided with inclined surfaces 14 , and the inclined surfaces 14 are inclined downward toward the outside.

[0035] The iron chips in the receiving groove will fall toward both ends along the inclined surface, and the chip removal holes on the side have a good chip removal effect.

[0036] A connecting shell 15 is installed at one end of the caliper body 1 away from the fixed jaw 11, and a mounting shell 16 is installed at one end of the connecting shell 15 away from the fixed jaw 11.

The platform 51 is slidably installed in the slide groove 171. Spring leaves 52 are respectively installed on the upper and lower sides of the platform 51. The two spring leaves 52 are staggered up and down, and the spring leaves 52 abut against the upper and lower sides of the slide groove 171.

[0041] The slider 5 is provided with a first oil filling hole 53 connected with the screw rod 2, and a sealing bolt is installed on the first oil filling hole 53. The transmission sleeve 3 is provided with a second oil filling hole 39 connected with the boosting chute 91, and the connecting shell 15 is provided with a first oil filling channel 151 connected with the second oil filling hole 39, and a sealing bolt is installed on the first oil filling channel 151.

[0043] After the lubricating oil enters the boosting chute, the arc-shaped bottom edge structure of the boosting chute 91 can better fit with the sphere, and the lubrication effect is good.

[0044] Chip removal pieces 55 are installed at both ends of the slider 5 . A conical scraper ring 56 is provided on the chip removal piece 55 . The inner ring of the conical scraper ring 56 abuts against the outer side of the screw rod 2 .

[0045] A step groove is provided on the side of the slider 5, and the chip removal piece is installed in the step groove by a limiting retaining spring. The conical scraper ring is trumpet-shaped. When the slider moves, the chip removal piece will scrape and clean the surface of the screw rod through the conical scraper ring to scrape off the iron chips on the screw rod.

[0046] A mounting frame 18 is provided at the top of the accommodating groove 17, and a chip guard plate 181 is provided at the top of the mounting frame 18. An opening 182 is provided on the chip guard plate 181. A movable baffle 183 is installed on the movable jaw 12. The movable baffle 183 is slidably set on the top of the chip guard plate 181. When the movable jaw 12 moves, the movable baffle 183 always covers the opening 182.

[0047] The movable baffle is provided with a mounting opening, which is clamped between the slider and the movable jaw.

[0048] The driving head 62 and the limiting clamping column 21 are both hexagonal heads. A driving sleeve 10 is detachably mounted on the driving head 62 , and the driving sleeve 10 is connected to a rotating handle. The booster shaft 6 and the push rod 61 are an integrated structure.

[0049] The driving head 62 and the limiting clamping column 21 can also be designed as other polygonal structures.

[0050] A positioning sleeve is rotatably mounted on the outer side of the driving sleeve 10 , and an indicator mark is provided on the positioning sleeve.

[0051] During operation, first match and install the drive sleeve 10 with the drive head, then rotate the positioning sleeve, align the indicator mark on the positioning sleeve with the No. 0 gear of the spiral line, and fix the identification plate to the transmission sleeve. When rotating at no load, the identification plate and the drive head rotate synchronously, so the indicator mark is always aligned with the No. 0 gear. After entering the boost state, the indicator mark and the drive head will rotate relative to each other. The operator can intuitively observe that the indicator mark will rotate along the spiral line and then rotate to different gears, thereby quantitatively controlling the clamping force.

[0052] Working process: When no-load, use a tool to twist the drive head 62, and the drive head 62 is connected to the inner hexagon of the boost shaft 6 through the outer hexagon, and the fixed steel ball 65 is installed in the fixed through groove 4 of the transmission sleeve 3. The fixed steel ball 65 is pressed and fixed by the elastic force of the fixed spring. Since it is no-load, the input torque of the drive head 62 is smaller than the fixed spring, and the boost shaft 6 is relatively fixed to the transmission sleeve 3 through the steel ball. The steel ball clamps the transmission sleeve 3 and rotates together, and the transmission sleeve 3 is fixed together with the limit gasket 4 by bolts, and is connected to the outer hexagon of the upper limit column 21 on the screw rod 2 through the inner hexagon of the limit gasket 4, so that the screw rod 2 rotates with the transmission sleeve 3, thereby achieving the purpose of quickly moving the movable jaw 12.

[0053] Boosting: After clamping the workpiece, continue to rotate the drive head 62, and continue to increase the torque after the fixed jaw 11 and the movable jaw 12 clamp the workpiece. When the elastic force of the fixed spring is less than the input torque, the fixed steel ball 65 is released from the relative fixation with the transmission sleeve 3, and the booster shaft 6 and the transmission sleeve 3 will rotate relative to each other. The booster shaft 6 continues to move inward through the thread with the transmission sleeve 3, and the push rod 61 passes through the tapered part to open the rolling element 92 in the retaining frame 9. The rolling element 92 moves outward, and then opens the retaining frame 9 and the front gasket. The front gasket squeezes the disc spring 8, and the disc spring 8 deforms, providing a reaction force to the front gasket, which is then transmitted to the screw rod 2 through the rolling element 92 and the retaining frame 9. The screw rod 2 is finally transmitted to the fixed jaw 11 and the movable jaw 12, thereby obtaining a greater clamping force.

[0054] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
