Embodiment Construction

[0020] use Figure 1-Figure 5 A labor-saving socket wrench according to an embodiment of the present invention will be described as follows.

[0021] Such as Figure 1-Figure 4 As shown, a labor-saving socket wrench according to the present invention includes a socket 1 and a handle 2, and also includes a bending unit 3, which is used to bend the handle 2 in any direction relative to the socket 1 , so that the nut or bolt is loosened by using the bending of the handle 2 and the sleeve 1 to generate a large torque. The bending unit 3 includes a fixed block 31, a connecting block 32, a rotating ball 33, a bevel gear 34, a swivel 35, a limiter Position pin 36, limit plate 37 and spring 38, sleeve 1 is installed at the lower end of described fixed block 31, and the upper surface of fixed block 31 is provided with a circular truncated groove with large upper end opening and small lower end opening, and fixed block 31 is in the circular truncated groove. On the side wall of the st...

Abstract

The invention belongs to the technical field of hardware tools, and particularly relates to a labor-saving socket wrench. The labor-saving socket wrench comprises a sleeve and a handle, and further comprises a bending unit, wherein the bending unit is used for bending the handle in any direction with respect to the socket, so that the bending of the handle and the socket is utilized to produce relatively large torque so as to unscrew a nut or a bolt; the bending unit comprises a fixing block, a connecting block, a rotating ball, a bevel gear, a rotating ring, a stop pin, a limiting plate and aspring; the socket is arranged at the lower end of the fixing block; a circular truncated cone-shaped groove having a large opening at the upper end and a small opening at the lower end is formed inthe upper surface of the fixing block; limiting teeth are arranged on the side wall of the circular truncated cone-shaped groove of the fixing block in an interval manner of one high and one low; eachlimiting tooth is arranged in the direction of a bus bar of the circular truncated cone-shaped groove; the connecting block is vertically arranged at the bottom of the circular truncated cone-shapedgroove of the fixing block; a spherical crown-shaped groove is formed in the upper surface of the connecting block; and a magnet is internally arranged in the upper part of the connecting block. The labor-saving socket wrench can realize the large torque unscrewing and the quick backout of the bolt or the nut after unscrewing.

Description

technical field [0001] The invention belongs to the technical field of hardware tools, in particular to a labor-saving socket wrench. Background technique [0002] A wrench is a commonly used installation and removal tool. Hand tools for turning bolts, screws, nuts, and other open or socketed fasteners whose threads hold bolts or nuts tightly by the principle of leverage. The wrench is equipped with a sleeve for clamping bolts or nuts at one or both ends of the shank. When in use, an external force is applied to the shank along the thread rotation direction to twist the bolts or nuts. Existing wrenches are divided into two types, one is when the handle is perpendicular to the sleeve, and the other is when the handle and the sleeve are on the same straight line. When the handle is perpendicular to the sleeve, it can provide a larger torque, which is convenient for bolts or nuts to be pulled. Loosen, but when the bolt or nut is loosened, due to the longer arm of the handle, ...
