Embodiment Construction

[0012] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0013] like figure 1 As shown, a wrench includes a socket head 1, a telescopic rod 2 and a rotation booster rod 5. The socket head 1 is a concave hexagonal cylinder, and it is characterized in that: one end of the telescopic rod 2 is connected to a sleeve The barrel head 1 and the other end are vertically connected to the rotation booster rod 5, and the sleeve head 1, the telescopic rod 2 and the rotation booster rod 5 are all made of aluminum alloy.

[0014] It is worth noting that the rotation booster rod 5 is provided with a small hole 4, which makes it more convenient to carry a labor-saving wrench.

[0015] In addition, a rubber sleeve 3 is provided on the rotation booster rod 5, which increases the friction between the human hand and the r...

Abstract

The invention discloses a wrench, and relates to the field of industrial machinery. The labor-saving wrench comprises a sleeve head, a telescopic rod and a rotary assistance rod, wherein the sleeve head is a cylinder which is of a hexagon shape, one end of the telescopic rod is connected with the sleeve head, and the other end of the telescopic rod is perpendicularly connected with the rotary assistance rod. People can conveniently disassemble or screw down a screw in a groove through the wrench, and a large amount of labor is saved through the rotary assistance rod when people disassemble the screw. Due to the fact that the sleeve head, the telescopic rod and the rotary assistant rod are all made of aluminum alloy materials, the service life of the labor-saving wrench can be prolonged.

Description

technical field [0001] The invention relates to the field of industrial machinery, in particular to a wrench. Background technique [0002] As we all know, the improvement of a country's comprehensive national strength depends on the progress and development of its own industry, and machinery and equipment are particularly important as the foundation of industry. A wrench is a commonly used mechanical tool. When we repair mechanical equipment, a wrench is used in many cases. The invention with the application number of 201110390866.4 discloses a wrench. The handle of the wrench is equipped with a wrench Grips. When in use, the extension and contraction of the handle and the handle can be adjusted according to needs, thereby adjusting the overall length of the handle, so that the screwing and dismounting of the bolts when the wrench is in use is more labor-saving and quicker. But this wrench also has some problems. Although this wrench can disassemble or tighten the screws ...
