Telescopic mounting/dismounting tool

Abstract

The invention belongs to the technical field of mounting / dismounting tool, in particular to a telescopic mounting / dismounting tool. The telescopic mounting-dismounting tool solves the problems that in the prior art the design is not reasonable, the control is inconvenient and a batch rod easily axially move. The telescopic mounting / dismounting tool comprises a cylindrical handle; one end of the handle is provided with a ratchet wheel assembly used for controlling the circumferential rotation direction of the batch rod and / or a circumferential locking batch rod; the batch rod axially moving relative to the ratchet wheel assembly is arranged in the ratchet wheel assembly in a penetrating manner; one end of the batch rod extends into the handle; a control mechanism used for axially locking the batch rod or releasing batch rod axial locking is arranged on the handle; and the batch rod is sleeved with the control mechanism. Compared with the prior art, the telescopic mounting / dismounting tool has the advantages that the design is more reasonable, the control of axially locking the batch rod or locking releasing state is convenient, and the axial locking effect is good.

Description

technical field [0001] The invention belongs to the technical field of assembly and disassembly tools, in particular to a telescopic assembly and disassembly tool. Background technique [0002] Assembly and disassembly tools are widely used in daily life and engineering technology fields. In order to adapt to various occasions and use them quickly and conveniently, various assembly and disassembly tools have been available in the existing market. For example: a disassembly tool with one-way or two-way circumferential rotation of the rod, a disassembly tool with an axially movable disassembly tool, and an axially fixed disassembly tool; these existing disassembly tools generally include : the handle is provided with a ratchet rod in the handle, and some also have a ratchet assembly, but these existing dismounting tools have such shortcomings: the length of the ratchet rod is set to be fixed, and in specific operations, when it is necessary to use In the case of long and shor...

AI Technical Summary

Problems solved by technology

For example: a disassembly tool with one-way or two-way circumferential rotation of the rod, a disassembly tool with an axially movable disassembly tool, and an axially fixed disassembly tool; these existing disassembly tools generally include : the handle is provided with a ratchet rod in the handle, and some also have a ratchet assembly, but these existing dismounting tools have such shortcomings: the length of the ratchet rod is set to be fixed, and in specific operations, when it is necessary to use In the case of long and short rods to facilitate the operation, it is more troublesome to use the fixed dismounting tool of the rod, and it is necessary to carry different types of dismounting tools, but in the current axial direction Among these mobile disassembly tools, when the axial locking and canceling of the axial locking are carried out on the batch rod, the axial locking of the batch rod is unstable, and the batch rod with poor axial lock control effect is easy to be axially locked. movement, in addition, it is inconvenient to operate when axially locking and canceling the axial locking of the batch rod

[0004] The above scheme is to control the axial locking and axial movement of the batch rod through the rotary structure, which can meet the requirements of use to a certain extent. However, the control effect of this scheme on the batch rod is still not ideal. It is inconvenient to control when the axial locking and canceling the axial locking. In addition, when the rod is axially stressed and the rod is in the axially locked state, the rod is still easy to move axially. The design of this scheme is still There are defects and it is not easy to be popularized and applied
