As follows:

As shown in FIGS. 3 and 4 again, when the assembly of the vise with waterproof structure of the present invention is completed, the elastic force of the elastic members 59 is used, and the retaining ring 545 is used to block the outer side of the outer side 312. As a result, the shaft set 54 can be restrained corresponding to the axis L, and the first and second baffle members 51 and 52 and the toggle members 53 are also positioned relative to the lead screw 40.

As shown in FIG. 5 again, when the operator inserts a tool 100 into the operation hole 629 of the knob set 62, and applies force to press the connecting member 623 toward the shaft set 54 (the springs 624 appear to be Compressed), the second clutch teeth 628 and the first clutch teeth 544 mesh with each other, and connect the connecting member 623 and the shaft set 54 to each other. When the operator rotates the tool 100, the stopper 546 can be inserted into the elongated hole 421, so that when the shaft set 54 rotates, the lead screw 40 can be rotated together to drive the movable clamp The jaw 22 approaches or is away from the fixed jaw 21 (see FIG. 1 for cooperation), and can clamp or release a workpiece (not shown).

As shown in FIGS. 3 and 4 again, when the movable jaw 22 has clamped the workpiece together with the fixed jaw 21, the operator first releases the pressing force on the connecting member 623, and then uses the springs The release elastic force of 624 can make the connecting member 623 away from the shaft set 54 and separate the second clutch teeth 628 and the first clutch teeth 544 from each other. At this time, when the operator rotates the connecting member 623 with the tool 100 again, the rotating member 621 is used to drive the pin rod 626 to move in parallel. The pin rod 626 is threaded on the lever 57 to drive the lever 57 is screwed forward with respect to the shaft set 54, and the lever 57 pushes the pushing member 58, the pushing member 58 pushes the toggle group 53, and through the toggle group 53 and the first The cooperation of the baffle member 51 and the second baffle member 52 can increase the clamping force of the movable jaw 22 relative to the fixed jaw 21, that is, the first baffle member can be adjusted by turning the knob set 62 The distance between 51 and the second baffle 52 is adjustable, and the clamping force of the jaw unit 20 can be adjusted.

Therefore, the present invention not only achieves the purpose of clamping the workpiece 200 with the use of the overall structure, but also uses the first leakage preventing member 33 to be sleeved between the shaft seat 31 and the lining member 32, and utilizes the second leakage preventing member 55 is set between the shaft set 54 and the inner annular surface 322, the second leakage preventing member 55 is disposed between the flange portion 542 and the inner annular surface 322, and the third leakage preventing member 56 is disposed Between the extending portion 543 and the inner surface 431, the fourth leakage preventing member 63 is disposed between the ring seat 61 and the shaft seat 31, and the fifth leakage preventing member 64 is disposed between the ring seat 61 and the The role of the knob set 62 can prevent external dust, fine debris, and water from infiltrating into the shaft seat 31, the body 10, and the torque adjustment unit 60, which can ensure that the mechanical parts inside the vise operate smoothly and extend Service life.

In summary, the vise with a waterproof structure of the present invention can achieve the purpose of stable clamping with the overall structure, and can produce a better waterproof effect, which can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention. Any simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still classified as This invention covers the patent.
