Rapid-operated wrench

Abstract

The invention discloses a rapid-operated wrench comprising a grab handle, a tool head and a pivoting and locating group; the grab handle comprises a pivoting end and a holding part; the tool head comprises a sleeving end and a driving end, the driving end is capable of driving a part to be driven, the sleeving end is provided with a first pivot lug, a second pivot lug and an accommodating groove arranged between the first pivot lug and the second pivot lug, and the pivoting end is arranged in the accommodating groove; and the pivoting and locating group is arranged on the grab handle and the tool head and composed of a control part, a locating part and an anti-drop device, wherein the control part is arranged at the first pivot lug, a ratchet hole and a second pivot lug, the locating part and the anti-drop device are arranged at the second pivot lug, the anti-drop device can prevent the locating part from being separated from the second pivot lug, the locating part can be switched between a first position and a second position after being pressed and is located at the first position, the tool head can be driven by the grab handle to rotate, the control part is located at the second position, and the grab handle and the tool head can rotate relatively.

Description

technical field [0001] The invention mainly relates to a wrench, in particular to a fast-operating wrench in which a handle and a tool can rotate relatively. Background technique [0002] refer to Figure 8 and Figure 9 , is a three-dimensional exploded view and a sectional view of an existing hand tool handle. It provides a hand tool handle capable of adjustment and positioning, which includes a handle 70, at least one tool head 80, and at least one pivotal positioning group 90 of the handle 70 and the tool head 80, wherein the handle 70 is at least A lug 71 protrudes from the upper and lower edges of one end respectively, and the corresponding end of the tool head 80 has a pivot ear 81 that can be clamped and pivoted between the two lugs 71, and the lug 71 and the pivot ear 81 are respectively formed with locking teeth. The embedded pivot hole 72 and the locking tooth hole 82, and the pivot positioning group 90 includes a positioning pivot 91, a limiting member 92, a re...

Problems solved by technology

[0004] The pivotal positioning group 90 designed in this way has the defect that there are many components, which increases the cost of parts and assembly costs, and cannot meet the demand for cost reduction.

[0005] In addition, since the return spring 93 normally pushes the positioning pivot 91 out of engagement with the handle 70, when the tool head 80 needs to be driven, the user needs to continuously press the positioning pivot 91 to engage the positioning pivot 91 Handle 70, such an operation mode limits that the user must hold the pivotal positioning group 90 and press the positioning pivot 91, thereby limiting the length of the force-exerting arm for holding the handle 70, and cannot provide a better grip. The holding position, and the continuous pressing of the positioning pivot 91 will affect the user's force on the handle 70, further preventing the user from effectively applying force.
