Abstract: A detachable and torque-adjustable cross wrench includes a primary bar and a torque-setting secondary bar, and an end of the primary bar is a socket insertion end and the other end of the primary bar is installed with an assistant turning handle provided for pivoting. A penetrating hole formed at a thickening middle section is provided for connecting the torque-setting secondary bar to form a cross wrench. The torque-setting secondary bar includes a plugging inner rod with a spacer ring slot, a force applying outer rod containing a torque-setting module, a handheld turning handle, an elastic pushing member, a torque-adjusting screw cap and a retaining ring. The torque-adjusting screw cap is provided for rotating and adjusting the torque-setting module to a predetermined torque value, so as to achieve an expected torque-setting.

Abstract: A quick release structure of a T-shaped ratchet wrench, and the ratchet wrench being comprised of a transverse force applying handle and a longitudinal acting handle, and a ratchet steering and a driving mechanism being installed at a junction of the two handles and provided for controlling a force applying direction, wherein a substantially polygonal plug end of the acting handle has a quick release structure comprising a sliding sleeve, an elastic member, a buckle, a top shaft and a latching bead, so that the sliding sleeve may be displaced to prop out the latching bead or sink the latching bead to achieve the effect of plugging an external connected assembling member securely or releasing the external connected assembling member quickly.

Abstract: A barrel type ratchet wrench with a snap-in structure including a wrench body having a ratchet acting head with a shallow groove adjacent to a hollow barrel. Moreover, a positioning bolt hole and a guide slot are positioned within the shallow groove. The positioning bolt hole is provided for receiving a direction switching lever and a positioning bolt of the ratchet module. A fixing plate and a snap plate are positioned under the direction switching lever. The lock plate has an external shape similar to the profile of the shallow groove and includes a snap portion, a long hole, a pushing portion and a bottom guide projection. The bottom guide projection and an elastic element are firmly positioned in the guide slot of the wrench body in such a way that the bottom guide projection of the engaging piece is constantly biased by the elastic element. The lock plate is fixed by screwing two screwing elements into corresponding screw holes of the wrench body.

Abstract: A barrel type ratchet wrench with a snap-in structure, including a ratchet acting head installed at a wrench body, a shallow groove formed at a position adjacent to a hollow barrel and having a positioning bolt hole formed at the center of the shallow groove for plugging a direction switching button and a positioning bolt of a ratchet module. A snap plate with an appearance similar to the profile of the shallow groove and having a snap portion, a long hole and a pushing portion is installed under the direction switching button, and a collar having a containing hole corresponsive to a locking component is disposed at the wrench body proximate to the ratchet acting head for containing an elastic member, and the pushing portion of the snap plate has a corresponding end plugged into the containing hole and normally abutted by the elastic member.

Abstract: A rotatable handle arrangement for a torque-adjustable wrench including a hollow sleeve fixed at a distal end of the moment arm by a fixing element. An internal toothed portion is formed in a stepped hole of the hollow sleeve and positioned adjacent to one side of the in-place-rotatable handle. In the normal state, the internal toothed portion is engaged with an external toothed portion of the in-place-rotatable handle by means of an elastic element. The torque-adjustable rod of a torque adjusting mechanism is driven by the in-place-rotatable handle for adjusting the torque value when the in-place-rotatable handle is pushed in the direction of the hollow sleeve so as to disengage the internal and external toothed portions from each other. In this way, an expected adjustment is achieved.

Abstract: A torque wrench having a force-acting rod with a handle portion as well as a driving head assembly. The driving head assembly includes an action portion having a polygonal insertion portion in cooperation with a unidirectional ratchet mechanism. In this way, a screw element can be directly tightened or loosened by means of the polygonal insertion portion.

Abstract: An assembly element for a hand tool including accessories of force-applying hand tools such as a socket, a connecting bar, a universal adapter, etc. A rubber ring groove is formed at a certain position of an external portion having a maximal circumference. A rubber ring with a polygonal anti-rolling portion fits into the rubber ring groove for protecting from an unexpected rolling action. Meanwhile, the rubber ring has different colors for an easy identification of the item number, size, type, etc.

Abstract: A detachable cross wrench includes a primary bar and a secondary bar. The primary bar has a thickening middle portion being formed at the center thereof. A turning handle is mounted on the other end of the primary bar. A lateral through hole is formed in the thickening middle portion for insertion of a secondary bar to create a cross type wrench. A longitudinal hole communicates the lateral through hole for receiving compression knob in cooperation with a resilient element and a positioning element. The compression knob has a slim portion in the middle thereof and an engaging portion at the lower portion thereof. Based on the above-mentioned configuration, the primary bar and the secondary bar can be easily and optionally engaged in place into one of the engaging grooves in the secondary bar for fulfilling the practical and safety requirements.
