Description

Quickly loosen and tighten the wrench

technical field

The utility model relates to a fast loosening and tightening wrench, in particular to a wrench which can be quickly unscrewed and tightened when disassembling and assembling long bolts.

Background technique

Although the wrenches supplied on the market are many in variety, they cannot satisfy the purpose of convenience, quickness and labor saving for the assembly and disassembly of long bolts. Although the disassembly and assembly of the long bolts can be accelerated with the crank handle, there are deficiencies such as effort and tool replacement.

Contents of the invention

The purpose of this utility model is to provide a kind of fast unscrewing and tightening wrench that can disassemble and assemble long bolts conveniently, quickly and labor-savingly for above-mentioned inadequacies.

The quick loosening and tightening wrench of the utility model is realized by adopting the following technical scheme: the quick unscrewing and tightening wrench includes a tool body, a sliding sleeve and a guide device, the tool body includes a rotating fulcrum, a handle, a sleeve and a connecting rod, and the rotating The fulcrum and the handle are set on the upper part of the connecting rod, the connecting rod is provided with a guide spiral guide rail, and the bottom of the connecting rod is provided with a sleeve; the sliding sleeve is clamped by the sliding sleeve assembly 1 and the sliding sleeve assembly 2 through a snap ring and set on the connecting rod. on the rod; the guide device includes a nut, a guide pin and a spring, and the guide pin is installed in the hole on the sliding sleeve assembly 2 through the nut and the spring.

The sleeve is an inner hexagonal sleeve.

The guide rail is a spiral guide rail.

The sleeve is connected with the connecting rod by a quick-change joint.

The guide device can be applied to wrenches of other shapes as required, and is not limited to the wrenches exemplified in the present invention.

When using the fast loosening and tightening wrench of the utility model, first use the function of the ordinary wrench to loosen the bolt. Press the guide pin by hand and pull it up to the upper part of the guide rail and loosen the guide pin. Repeat this to quickly remove the bolt. When tightening, use the function of the ordinary wrench to screw the bolt into the screw hole first, then completely screw the bolt into the screw hole through the repeated top-down movement of the sliding sleeve, and then tighten the bolt to the required pre-tightening torque through the tool body.

The utility model has the advantages of reasonable design, simple structure and low cost, and is suitable for market promotion. Due to the guide rail and the guide device, it is convenient, fast, labor-saving and practical to disassemble and install the long bolts.

Detailed ways

Referring to accompanying drawings 1-2, the quick loosening and tightening wrench of the present utility model comprises tool body 1, sliding sleeve and guiding device, and tool body 1 comprises rotation fulcrum 2, handle 3, sleeve 4 and connecting rod 5, and rotation fulcrum 2 And the handle 3 is arranged on the upper part of the connecting rod 5, the connecting rod 5 is provided with a guide rail 6, and the bottom of the connecting rod 5 is provided with a sleeve 4; the sliding sleeve is clamped by the sliding sleeve assembly 1 7 and the sliding sleeve assembly 2 8 through the circlip 9 Connected and set on the connecting rod 5; the guide device includes a nut 10, a guide pin 12 and a spring 11, and the guide pin 12 is installed in the hole provided on the sliding sleeve assembly 2 8 through the nut 10 and the spring 11.

The sleeve 4 is an inner hexagonal sleeve.

The guide rail 6 is a spiral guide rail.

The sleeve 4 is connected with the connecting rod 5 by a quick-change joint.

The guide device can be applied to wrenches of other shapes as required, and is not limited to the wrenches exemplified in the present invention.

When using the fast loosening and tightening wrench of the utility model, first use the function of the ordinary wrench to unscrew the bolt, and then hold the rotating fulcrum 2 (ball head part) with one hand, and move the sliding sleeve to the lower part of the guide rail 6 with the other hand , press down the guide pin 12 by hand and pull it up to the upper part of the guide rail 6 and loosen the guide pin 12, so that the bolt can be quickly removed by repeating this. When tightening, use the function of the ordinary wrench to screw the bolt into the screw hole first, then completely screw the bolt into the screw hole through the repeated top-down movement of the sliding sleeve, and then tighten the bolt to the required pre-tightening torque through the tool body.
