摘要： The present invention discloses a force relieving mechanism and a ratchet clamp having a force relieving mechanism. The force relieving mechanism includes a first ratchet member, a second ratchet member, a locking member, an actuating member and a restoring member. A first clamp arm of the ratchet clamp is fixedly arranged with a first ratchet member having a first set of ratchets, and a second ratchet member having a second set of ratchets is coupled to the second clamp arm. The second ratchet member is provided with a first hole, the locking member passing through the first hole and being rotatable and translationally movable in the first hole. The actuating member applied a first actuation and a second actuation in turn to the locking member so as to cause the second set of ratchets to be detached from the first set of ratchets.

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.

摘要： The invention provides a ratchet clamp, comprising a first clamp arm, a second clamp arm and a ratchet mechanism provided between the first clamp arm and the second clamp arm. An elastic member is arranged between the ratchet mechanism and the second clamp arm. The ratchet mechanism includes a toothed bar, a pivoting member. The pivoting member includes a toothed piece, a housing and a lever. During clamping, the pivoting member pivots in whole within a certain range under the effect of the elastic member, and the toothed bar and toothed piece are engaged by undercut, maintaining the clamping force, and the elastic member protects the engagement between the toothed bar and the toothed piece from sliding apart. When opened, the interference fit between the toothed bar and the toothed piece enable the user to use small force pulling the lever to disengage the toothed piece, and also prevent accidental unloading force from opening the ratchet mechanism. The self lock state of the ratchet clamp of the invention is very safe and stable, the maximum clamping force at the jaw opening portion can reach about 50 Kg, and 85% of the maximum clamping force can be maintained after the user releases the clamp arms.

摘要： The present invention discloses a thread-locking assembly characterized by comprising an externally threaded member with external thread and a threaded member with thread fitting with the externally threaded member, wherein the externally threaded member is movable relative to the threaded member through the engagement of the external thread and the thread, and a blocking member which is arranged outside the externally threaded member. The inside of the blocking member is provided with projections. There is space between the projections and the externally threaded member. When the externally threaded member inclines under force, friction is produced between the externally threaded member and the blocking member to perform the locking function.

摘要： A glue bottle with flow regulation comprises a bottle body, a bottle cap, and a liquid outlet cap engaged with the bottle cap through thread. The bottle cap is partially contained in the liquid outlet cap. A cavity is formed between the inner wall of the liquid outlet cap and the outer wall of the bottle cap. and is provided with a first opening and a second opening. A seal body is arranged on the top part of the bottle cap, and is positioned inside of the cavity. The position of the seal body in the cavity is adjusted by rotating the liquid outlet cap relative to the bottle cap. The closer the seal body is to the second opening, the smaller the gap is between the liquid outlet cap and the bottle cap. The glue bottle is capable of precisely controlling the quantity of the glue flowing out.

摘要： The present application discloses a hook assembly, which is used to be connected to a densely gridded rack. The hook assembly of the present application comprises a main body and a top connecting portion, wherein the main body and the top connecting portion are fixedly connected, and the top connecting portion is configured to be detachably connected to the rack. The width of the top connecting portion is greater than the spacing between adjacent longitudinal metal wires. The top connecting portion is provided with a receiving groove, the receiving groove is provided along the length direction of the top connecting portion, and the receiving groove is configured to receive a longitudinal metal wire. The shelving assembly provided in the present application can be reliably connected to the densely gridded rack without reducing the width of a top plate, so as to avoid the interference of the longitudinal metal wires. Most of the sizes of the shelving assembly remain unchanged, so as to solve the technical problems existing in the prior art with minimal modification and cost. It is also possible to increase the width of the top connecting portion to further improve the load-bearing capacity of the shelving assembly.
