Description
Technical Field
[0001] The utility model relates to the technical field of clamps, and more specifically to a portable fixed clamp. Background Art
[0002] A fixing clamp is a tool used to fix pipe connection components. Its main purpose is to ensure the stability and safety of the pipe connection.

[0004] First, when the existing fixed clamp is in use, the size of the clamp ring is fixed, so the object cannot be clamped well during use.
[0005] Second, when the existing fixing clamp is used, bolts and nuts are usually used to fix the upper clamp block and the lower clamp block, but the clamp may become loose and fall off after a long time.
[0006] Cut three: The existing fixing clamp has no bottom support when in use, and the fixing clamp without bottom support may be easily displaced or loosened after installation due to lack of stability. Utility Model Content

[0014] Technical effects and advantages of the utility model:
[0015] 1. When the object fixed in the fixing clamp is small, the first bolt is rotated so that the bottom of the first bolt abuts against the fixing plate and moves downward to clamp the object. The purpose of setting the hollow round block is to keep the position of the first bolt in the middle of the fixing plate when it rotates, and the setting of the connecting rod and the first spring can make the connecting rod lift the fixing plate to keep it installed on the upper clamping block, which is beneficial to ensure that even small objects can be firmly fixed in the clamp and are not easy to loosen or shift.
[0016] 2.

[0017] 3. The utility model has a support at the bottom of the fixed clamp. The knob is rotated to make the transmission rod start to rotate. When the transmission rod starts to rotate, the rear worm starts to rotate. When the worm rotates, the worm wheel starts to rotate. At this time, the threaded rod rotates to make the top cylinder move upward. At this time, the second spring starts to rebound and the auxiliary rod starts to move upward, bearing the pressure of the upper clamp block and the lower clamp block. The bottom plate is placed on the ground to provide support for the clamp, which is conducive to ensuring the stability of the fixed clamp when in use, so that it is not easy to shake or move due to external force.
