Manual clamp

A manual clamp, comprising:

• a sliding rod;
• a fixed clamp body which is fixedly connected to one end of the sliding rod;
• a movable clamp body which is removably connected to the sliding rod;
• a movable clamp head which is removably connected to the movable clamp body;
• a handle which is rotationally connected to the movable clamp body, wherein the handle comprises a first side plate and a second side plate which are oppositely provided, and a reinforcing member fixed between the first side plate and the second side plate, wherein the reinforcing member is arranged on one end of the handle away from the movable clamp head, and the first side plate and the second side plate are respectively located on both sides of the movable clamp body and are connected to the movable clamp body through a first pin shaft, one end of the first side plate that is close to the movable clamp body and one end of the second side plate that is close to the movable clamp body are both processed into shapes of cams to form a cam portion which is configured to come into contact with or disengage from the movable clamp head by operating the handle, and the cam portion being further configured to exert a driving force to the movable clamp head through the contact with the movable clamp head, thus being able to drive the movable clamp head to move toward the fixed clamp body to realize clamping;
• a ratchet which is provided on the movable clamp body;
• a pawl which is matched with the ratchet and is rotationally provided between the first side plate and the second side plate;
• an elastic element which is configured to exert an elastic force to the pawl, such that the pawl meshes with the ratchet;
• and
• a pawl sheath which is connected to the pawl and is configured to be operated to overcome the elastic force of the elastic element, such that the pawl is out of mesh with the ratchet.
