[0002] Clamps are an indispensable part of any toolbox, playing a vital role in both home repairs and professional manufacturing. Designed to firmly grasp, hold, or clamp objects, clamps maintain stability during various tasks, improving efficiency and safety. Made of high-strength materials, they are highly durable, usable in harsh environments, and have a long service life. Relative to their functionality, clamps are generally reasonably priced, making them an economical and practical choice for both individual users and professionals. However, currently available clamps have significant drawbacks: they are inconvenient to clamp, and lack pre-clamping force after clamping, potentially causing objects to slip out. Therefore, designing a clamp with an improved structure is essential. Utility Model Content

A second fixed seat is fixedly connected to the support base, and a first pin is fixedly connected to the second fixed seat. The left handle and the right handle are rotatably connected to the first pin. A fourth pin is fixedly connected to the left handle and the right handle. A lock is rotatably connected to the fourth pin, and a spring is provided on the lock and the fourth pin.

[0005] As a further technical solution of this utility model, a locking handle is fixedly connected to the latch.

[0006] As a further technical solution of this utility model, a right-side handle is fixedly connected to the right-side handle, and a left-side handle is fixedly connected to the left-side handle.

[0007] As a further technical solution of this utility model, the support base is provided with symmetrical positioning through holes, and a first fixing seat is fixedly connected to the support base.

[0008] As a further technical solution of this utility model, a toothed rod is slidably connected to the first fixed seat, a threaded rod is fixedly connected to the toothed rod, and a rubber head is fixedly connected to the threaded rod.

[0009] As a further technical solution of this utility model, one end of the second pin is fixedly connected to the right handle, and the other end of the second pin is fixedly connected to the left handle. The right connecting rod and the left connecting rod are rotatably connected to the second pin.

[0010] As a further technical solution of this utility model, the right connecting rod is close to the right handle, the left connecting rod is close to the left handle, one end of the right connecting rod is rotatably connected to the third pin, the other end of the third pin is rotatably connected to the left connecting rod, and the third pin is fixedly connected to the toothed rod.

[0011] The improved clamp structure provided by this utility model has the following advantages: A first and second fixed base are fixed to the support base; the right and left handles are rotatably connected to the first pin, supported by the second fixed base and the first pin; and the right and left connecting rods are rotatably connected to the second pin, supported by the second pin, the right handle, and the left handle. Pulling the right and left handles causes them to rotate around the first pin, which in turn causes the right and left connecting rods to move. Finally, the threaded rod, the threaded bar, and the rubber head slide in the through hole of the first fixed base, and the locking handle is activated, causing the locking buckle to rotate around the fourth pin. The right and left handles are locked by the spring and the locking buckle, making operation convenient and ensuring a secure lock. Attached Figure Description
