Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings, but the claimed protection scope is not limited to the description.

[0040] In this example, if figure 1 , figure 2 As shown, the flexible socket wrench includes a handle 1, a sliding rod 2, a wire drawing 3, a spring A4, a flexible sleeve 5, and a connector 6. The structural relationship is as follows:

[0041] The upper end of the flexible sleeve 5 is fixedly connected to the lower end of the handle 1, the sliding rod 2 is slidably installed in the handle 1, the upper and lower ends of the spring A4 are respectively fixedly installed between the sliding rod 2 and the handle 1, and the drawing wire 3 passes through the upper end of the spring A4 and is fixedly tied to the sliding On the pull rod 2, the drawing wire 3 also passes through the tube of the flexible sleeve 5. The lower end of the drawing wire 3 is connected to the upper end of the cylindrical guide rod 61...

Abstract

The invention discloses a flexible socket wrench, which comprises a handle, a sliding rod, a drawing wire, an elastic part, a flexible sleeve and a connecting head. The structure of the connecting head is composed of a ratchet mechanism and a gear mechanism inside. When working, the flexible sleeve is used to ensure that the socket wrench can bend in and out on the path of disassembly, making the disassembly flexible and convenient. After the direction is determined by the reversing mechanism, the ratchet mechanism is driven by wire drawing, thereby driving the gear mechanism , and finally drive the connecting square head at the lower part of the connecting head to drive the sleeve to tighten or disassemble the nut.

Description

technical field [0001] The invention relates to a socket wrench, in particular to a socket wrench structure that can be used in a narrow space. Background technique [0002] The current mechanical or electronic assembly wrenches are basically rigid wrenches, such as dead end wrenches, adjustable wrenches, socket wrenches, etc. When the internal structure of many complex machines needs to be repaired and disassembled, adjustment screws will be involved. The internal space structure is very narrow. Generally speaking, the external parts are removed first, and then the internal parts are disassembled. At this time, a lot of man-hours and labor will be wasted. The current wrench can be extended to the inside for disassembly and assembly by extending the handle, but the extended handle cannot be bent, which cannot be realized for some disassembly and assembly where the path of extension is not a straight line. Therefore, there is a need for a flexible wrench that can disassemble...
