Description

Telescopic handle wrench

Technical Field

The utility model relates to a spanner field particularly, relates to a flexible handle spanner.

Background

The wrench is a common mounting and dismounting tool, but when the space of the assembly point is narrow, the handle of the wrench is easily blocked when the wrench is screwed, so that the wrench cannot be screwed continuously, for example, when the assembly point is close to the ground, if the handle of the wrench is longer than the distance from the assembly point to the ground, when the handle contacts the ground after the wrench is screwed, the wrench cannot be screwed continuously, the wrench needs to be reset again, and the operation is complicated. And to the tip great and the less part of assembly department, can not use box spanner, because box spanner passes from great tip, the hole of its spanner head just must be greater than the assembly point, can't implement the assembly action, if use open-ended spanner, its spanner head intensity is not enough, is propped open by the assembly part easily and warp, especially when being used for the part that needs very big power to accomplish the assembly like injection molding machine shooting mouth, open-ended spanner can't use. Patent publication No. CN106112901A discloses a telescopic and lockable wrench with adjustable handle length, which has only one handle and can be locked when telescopic, and can not solve the problem of narrow space of assembly points.

Example 1

As shown in fig. 1, a telescopic handle wrench comprises a wrench head 1 and two wrench handles 2; the two wrench handles 2 are symmetrically arranged on two sides of the wrench head 1; two spanner handles 2 are telescopic handles.

In the specific implementation process, the telescopic handle can use a telescopic rod.

In this embodiment, each of the two wrench handles 2 is composed of a fixed cylinder 21 and a sliding rod 22 sleeved in the fixed cylinder 21; one end of the fixed cylinder 21 is connected with the wrench head 1; the inner cavity of the fixed cylinder 21 and the sliding rod 22 are both in a circular truncated cone shape; one end of the inner cavity, which is far away from the wrench head 1, is a smaller bottom surface of the circular truncated cone; one end of the sliding rod 22 close to the wrench head 1 is a larger bottom surface of the circular truncated cone; the area of the bottom surface of the sliding rod 22 at the end close to the wrench head 1 is larger than that of the bottom surface of the inner cavity at the end far away from the wrench head 1.

In the specific implementation process, spanner handle 2 does not set up the locking, makes it can freely stretch out and draw back, when it is obstructed, can directly twist another spanner handle 2, and the spanner handle 2 that is obstructed this moment can contract automatically, reduces the operation of knowing the locking.

In this embodiment, the wrench head 1 is provided with a hexagonal hole 11.

In the present embodiment, the fitting hole 12 is included; the assembly hole 12 is formed by connecting one end of the rectangular part 121 in the length direction with the bottom edge of the isosceles triangle part 122; the other end of the rectangular part 121 in the length direction is communicated with the hexagonal hole 11; the length of the waist of the isosceles triangle is smaller than the side length of the hexagonal hole 11.

In the specific implementation process, when a component which is larger at the end part and smaller at the assembly point is used, the hexagonal hole 11 is used for penetrating through the end part, and the component is installed or disassembled by using the smaller assembly hole 12 after reaching the assembly point.

In this embodiment, the end of the sliding rod 22 away from the wrench head 1 is connected to the protrusion 221.

In the specific implementation process, when the opening of the fixed cylinder 21 is upward, the sliding rod 22 will automatically retract into the fixed cylinder 21, and the protrusion 221 is provided for limiting, so as to prevent it from completely entering the fixed cylinder 21 and not being easily taken out.

In this embodiment, the wall thickness of the fixed cylinder 21 is 5mm to 10mm.

In this embodiment, the length of the sliding rod 22 is greater than the depth of the fixed cylinder 21.

In specific implementation, the length of the sliding rod 22 is greater than the depth of the fixed cylinder 21, so that the sliding rod 22 can be prevented from completely entering the fixed cylinder 21.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
