Abstract

A quick clamping type vice in which a chuck and a spring are disposed in a main base seat. The chuck is substantially U-shaped and an inner side of the bottom of the chuck is formed with a semicircular thread facing upward. A cover board is disposed on the upper side of the chuck and locked with the chuck to form an integral body. The spring is disposed right under the chuck. The thread rod passes through the main base seat and ride on the bottom of the chuck. The spring pushed the chuck upward to make the thread of the chuck engaged with the thread rod. When the cover board is depressed, the chuck is vertically moved downward and disengaged from the thread rod. At this time, the thread rod is liberated and can be quickly slided. When releasing the cover board, the spring makes the thread of the chuck again engaged with the thread rod. Accordingly, the clamping and loosening operation of the vice can be quickly performed.

Claims

1. A quick clamping type vice comprising:

a main base seat including an upper end and a deep socket formed in said upper end of said main base seat, said main base seat including front and rear end faces and several through holes passing through said front and rear end faces;

a back seat disposed opposite to the main base seat;

a clamping block including a clamping end face and a back face disposed between said main base seat and said back seat, said clamping block cooperating with said back seat for clamping a workpiece, said clamping end face of said clamping block being formed with rough teeth mesh and cross channels and said back face of said clamping block opposite to said clamping end face including several holes;

a chuck disposed in said deep socket of said upper end of said main base seat, said chuck having an upper side, a U-shaped cross section with a bottom portion and a bottom face, said bottom portion of said chuck being formed with a 180 degrees thread and said bottom face formed with an upwardly extending downward facing recess;

a spring disposed in said deep socket of said main base seat and the recess of the chuck for upward pushing and restoring the chuck to a home position;

a cover board disposed on and engaging said upper side of said chuck, and a pin connecting said cover board to said chuck to form an integral body for depression of said chuck against the face of said spring;

a thread rod including a first end and a handle at an opposite end thereof, said thread rod passing through said main base seat and riding on said chuck, said first end of said thread rod being guided and locked in the hole of said block face of said clamping block for driving the clamping block to move; and

,

several guide rods respectively passing through said through holes of said main base seat and fixedly inserted into the holes of said back face of said clamping block for restricting and stabilizing the moving direction of said clamping block, characterized in that at the same time said thread rod rides on the bottom of said chuck in said deep socket of said main base seat with said thread of said chuck engaging said thread rod via the resilient force of said spring under said chuck, the thread of the chuck stably engaged with the thread rod by 180 degrees, and when said cover board on said upper side of said chuck is depressed to thereby move said chuck downward to disengage from said thread rod and temporarily release said thread rod and when said cover board is released, the thread of said chuck again engages said thread rod, and when said thread of said chuck is disengaged from said thread rod, said clamping block being free to move, while when said thread of the chuck is engaged with the thread rod, via said handle, said rod being rotated to drive said clamping block to clamp the workpiece.
