Currently, most pipe clamps on the market are composed of fixed jaws, movable jaws, pipe clamp handles, adjustment nuts, etc. The fixed jaws and the pipe clamp handles are fixed together. The front end of the pipe clamp handle is a fixed jaw. The inner side of the fixed jaw is a V-shaped tooth surface, and the front end of the movable jaw is a V-shaped tooth surface. The movable jaw is driven to move by the adjusting nut to change the size of the jaw opening to work. It is widely used in clamping and knob round pipe workpieces. When in use, the adjusting nut is rotated, and the nut and the thread are rotated to adjust the movement of the movable jaw, so that the opening size of the movable jaw relative to the fixed jaw changes, and the round pipe workpiece is clamped. However, the size of the opening of the pipe clamp in the prior art needs to be frequently adjusted by the adjusting nut, which makes the adjustment process more troublesome. Utility Model Content

[0017] See also Figure 1-3 The utility model provides a technical solution: an open slider adjustment type pipe clamp, comprising a pipe clamp handle 1, an upper jaw 4 is arranged on one side of the top of the pipe clamp handle 1, a pipe clamp handle inner cavity 8 is opened inside the pipe clamp handle 1, a moving column 3 is arranged at the center of the pipe clamp handle inner cavity 8, the top of the moving column 3 passes through the top of the pipe clamp handle 1, a lower jaw 2 is arranged on the top of the moving column 3, the bottom of the moving column 3 passes through the bottom of the pipe clamp handle 1, a card slot 5 is arranged at the bottom of the pipe clamp handle 1 and on the outer surface of the moving column 3, a fixed block 6 is sleeved on the surface of the moving column 3, the diameter of the fixed block 6 is larger than the diameter of the moving column 3, a plurality of card blocks 7 are arranged at the bottom of the fixed block 6, and the card block 7 is snap-fitted and connected to one of the card slots 5.

[0018] Furthermore, a limit block 9 is provided on the outer surface of the movable column 3 and located at the inner cavity 8 of the pipe clamp handle, and the length and width of the limit block 9 match the bottom length and width of the inner cavity 8 of the pipe clamp handle.

[0019] Specifically, a limit block 9 is provided on the outer surface of the movable column 3 and located in the inner cavity 8 of the pipe clamp handle, which mainly plays a limiting role to prevent a certain deviation from occurring during the movement of the movable column 3, thereby causing a certain angle between the lower jaw 2 and the horizontal plane, thereby affecting subsequent use.

[0020] Furthermore, through holes are provided at both ends of the top and bottom of the limit block 9 , and a limit rod 10 is provided at the through hole. Both ends of the limit rod 10 are connected to the top and bottom of the inner cavity 8 of the pipe clamp handle.

[0022] Working principle: When in use, the user first removes the fixing block 6, and then moves the lower jaw 2 to the top of the pipe clamp handle 1. At this time, the bottom of the limit block 9 is located at the bottom of the inner cavity 8 of the pipe clamp handle. At this time, the scale value is "0", and then the moving column 3 is moved upward. During the movement, the limit block 9 will be moved upward, thereby moving the lower jaw 2, and then changing the opening size of the lower jaw 2 and the upper jaw 4. During the movement of the new type, the position of the lower jaw 2 is changed by moving the moving column 3, which is simpler to adjust than the prior art in which the position of the upper jaw 4 is changed by adjusting the nut.

[0023] After the movement is completed, the fixing block 6 is again sleeved on the surface of the moving column 3, and then the clamping block 7 at the bottom of the fixing block 6 can be connected to the clamping groove 5, so as to fix the moving column.
