摘要： A ratchet wrench with a grip that prevents the ratchet wrench from slipping out of a person's hands includes an elongated body, a ratchet device and a wrench head. The elongated body has two opposite ends and a central segment formed between the two ends of the elongated body. The ratchet device is mounted at one of the ends of the elongated body, and the wrench head is formed at the other end of the elongated body. The grip is mounted on the central segment of the elongated body to prevent the ratchet wrench from slipping out of a person's hands as the person uses the ratchet wrench to perform a task, such as tightening a fastener.

摘要： A gear wrench allowing easy force application, having: a head, formed with a receiving compartment thereon for receiving a gear ring, the head extending along a first plane; a tail, extending along a second plane; and a neck, provided between and integrally formed with the head and the tail; characterized in that: the first plane is parallel to the second plane, and the neck obliquely extends from the head towards the tail to form a height difference between thee head and the tail. As such, the vertical component of force may be eliminated or minimized so as to effectively reduce occupational hazards; the horizontal component of force may also be increased such that the operator only requires a lower force to effectively tighten or loosen up a fastener.

摘要： A hydraulic torque wrench having a separate ratchet unit and hydraulic cylinder drive unit connectable by an overlapping cylindrical connection at selected angles of rotation providing clearance in use. The hydraulic cylinder actuates the ratchet mechanism by a connecting rod traveling through the overlapping cylindrical connection and engaging a pivotable drive plate. The ratchet may have a male drive shaft for driving a socket, or a female driver such a hex or spline wrench. The ratchet unit case may be integral, or split for removable accesses to the ratchet mechanisms. The cylinder unit hydraulic connections may be separate rotatable connections or a single connection and collar, allowing three-way rotation. Attachments for the hydraulic unit include a pipe flange spreader, a nut splitter, scissor action shears, and a lift/spreader for lifting an object from a flat surface or spreading surfaces apart. A reaction bar affixes to the drive unit body.

摘要： A reversible ratchet-type wrench includes a handle and a head extended from the handle and having a hole. A web is defined between the handle and the head, and a cavity is defined in the web and communicated with the hole. The web further includes a compartment having a first end communicated with the cavity and a second end communicated with outside, thereby leaving a bridge in the web. A drive member is rotatably mounted in the hole of the head. A pawl is mounted in the cavity and includes a first side with ratchet teeth for releasably engaging with teeth on an outer periphery of the drive member. A switch member includes a turn-piece for manual operation and an actuating plate extended from the turn-piece and rotatably received in the second end of the compartment of the head. The switch member is switchable between two positions for changing ratcheting direction of the drive member. A biasing arrangement is mounted in the cavity and between the pawl and the actuating plate for biasing the ratchet teeth of the pawl to engage with the teeth of the drive member.

摘要： A wrench includes a drive head, a drive member, a plurality of locking teeth mounted on either one of the inner wall of the drive head and the drive member, and a locking device mounted on either one of the inner wall of the drive head and the drive member. The locking device includes at least two driving blocks each formed with a locking end engageable with the locking teeth to drive the drive member. The locking ends of the at least two driving blocks are respectively engaged with the locking teeth at different time. Thus, the locking device has a smaller driving angle for driving the drive member.

摘要： A ratchet wrench having a rigid locking structure includes a wrench body, a ratchet wheel, a pawl member, and a restoring member. Thus, the support blocks of the pawl member are urged on the wall of the receiving chamber of the wrench body, thereby forming a double-support or multi-support structure between the pawl member and the wall of the receiving chamber of the wrench body, so that the locking teeth of the pawl member are engaged with the ratchet teeth of the ratchet wheel actually, closely, rigidly and stably, thereby increasing the efficient torque of the ratchet wrench, and thereby facilitating the user operating the ratchet wrench.
