摘要： The present invention discloses a ratchet clamp comprising a first clamping arm and a second clamping arm which are pivotally connected with each other via a connecting shaft so as to be opened and closed relative to each other, a ratchet assembly, a swing assembly and a control assembly provided between the first clamping arm and the second clamping arm; the ratchet toothed assembly has a plurality of first ratchet teeth and a plurality of second ratchet teeth which are juxtaposed and are misaligned with each other; the swing assembly and the ratchet toothed assembly are moved away from or towards each other with the connecting shaft as the axial center of rotation; a latch member of the control assembly has at least a first pawl and at least a second pawl, a wrench member of the control assembly is used for toggling the latch member to be moved, the first pawls and the second pawls are respectively engaged with the corresponding first ratchet teeth and second ratchet teeth when the latch member is moved to an engaged position, and the first pawls and the second pawls are respectively moved away from the corresponding first ratchet teeth and the second ratchet teeth when the latch member is moved to a released position. With the misaligned ratchet tooth design, the tooth profile may not be reduced, thereby increasing the structural strength, so that the overall clamping force is greatly enhanced.

摘要： Disclosed is a wrench, which is used for wrenching a workpiece and comprises a unidirectional transmission mechanism. The unidirectional transmission mechanism comprises rollers (112), a first member (110) and a second member (111) at least partially sheathed in the first member. The first member (110) is fixedly provided at a wrenching portion of the wrench, and the second member (111) is used for mating with the workpiece. The directions of the rotating torque from the wrenching portion are a first direction and a second direction along the axis of rotation of the first member (110). With regard to one of the rotating torque of the first direction and the rotating torque of the second direction, the second member (111) is stationary relative to the first member (110) so as to output the rotating torque to the workpiece; and with regard to the other one thereof, the second member (111) rotates relative to the first member (110) without outputting the rotating torque to the workpiece. The torque of the unidirectional transmission mechanism can meet the demand of using a wrench, and at the same time, the unidirectional transmission mechanism remains silent in use and has the characteristic of wear resistance of bearings.

摘要： The present invention provides a hand tool with reliable connections comprising: a working unit having a working end and a handle end opposite to the working end; a handle being mounted on the handle end of the working unit and having a working unit end and a knocking unit end; a knocking unit being mounted on the knocking unit end of the handle. The connecting part between the knocking unit and the handle end of the working unit is a contacting surface, the handle end or the contacting surface is configured as a deformable and non-rigid contact, realizing the reliable connection between the working unit and the knocking unit. The deformable and non-rigid contact is realized by the configuration of at least one of the contacting surface and the handle end being configured to be tooth-shaped, the tooth-shape can deform and form a gapless engagement with the contacting surface. This configuration lowers the precision requirements for the production of each part; saves the costs; achieves reliable connections among the working unit, knocking unit and the handle of the hand tool; and disperses the impact force that damages the handle.
