A tie plier is provided, which includes a head, a locking assembly, a first and second handle. The first handle is connected to an end of the head, the locking assembly is movably connected to the head, a ratchet assembly is provided on the second handle and is connected with the locking assembly, a reset tension spring is connected between the second handle and the head, a jaw is provided on the head and is arranged close to the locking assembly, and a cutting assembly is provided at a side of the jaw. The tie plier can be operated by one hand to tighten the tie. Moreover, the tightening mechanism is compact and simplified in structure, and a holding angle between the first and second handle can be adjusted, thus a one-handed operation can be carried out more conveniently, and tie tightening operations in various special occasions can be made.

Disclosed are a ceramic tile leveling bracket, pushing and clamping pliers and a ceramic tile leveling and laying system. The ceramic tile leveling and laying system comprises: a ceramic tile leveling bracket (1), an insertion block (2) and pushing and clamping pliers (3), wherein the ceramic tile leveling bracket (1) is provided at the junction between two adjacent ceramic tiles (4), one end of the insertion block (2) is inserted into an insertion block through hole (16) of the ceramic tile leveling bracket (1), and the pushing and clamping pliers (3) push and clamp the insertion block (2) into the insertion block through hole (16), so that an insertion block bottom surface (21) is tangent to upper surfaces of the two ceramic tiles (4). The ceramic tile leveling and laying system is easy to operate, and helps to improve the laying efficiency and laying quality.

Bee keepers, or apiarists, need to regularly inspect their hives in an apiary. In addition, the goal of the apiary is to collect products from the hive. To perform these maintenances chores, the bee keeper typically is required to remove a frame from the hive. Embodiments of the Bee Frame Extractor Grip are comprised of a pair of handles, a left-side grip assembly, and a right-side grip assembly. The pair of handles connect the left-side grip assembly and the right-side grip assembly via bolts that pass through the upper arms of both L-brackets and into the ends of the handles.

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.

A replacement structure of a pair of pliers contains: a first grip, a second grip, multiple screw bolts, and a first plier set and a second plier set which are alternatively rotatably connected with the first grip and the second grip. The first grip includes a first connection disc having multiple first orifices, and the second grip includes a second connection disc having multiple second orifices. The first plier set includes a first clamp arm and a second clamp arm, the first clamp arm has multiple third orifices, and the second clamp arm has multiple fourth orifices. Alternatively, when the second plier set is rotatably connected with the first grip and the second griping, the second plier set includes a third clamp arm and a fourth clamp arm, the third clamp arm has multiple fifth orifices, and the fourth clamp arm has multiple sixth orifices.

A lock structure is constituted of a gear and an engagement/disengagement switching section. The gear is disposed concentric with a turning center of an operating lever. The engagement/disengagement switching section is provided with an engagement pawl such that the engagement pawl can move toward and away from the gear. The engagement pawl is connected to a switching lever to form a substantially T-like shape, and the switching lever is pivotally supported by a body section of the engagement/disengagement switching section. A locking operation of the switching lever switches between the locked state and unlocked state of the operating lever. In an engaged state, a gap having an opening angle of in a direction in which the operating lever loosens is formed between a tooth groove of the gear and the engagement pawl.
