Electric expander convenient to operate

Abstract

The invention relates to the technical field of emergency rescue and disaster relief equipment, and discloses an electric expander convenient to operate. The electric expander comprises an operating handle. A base is fixedly connected with one end of the operating handle, a power line is movably nested in a side surface of the base, a plug is fixedly connected with the other end of the power line,a positioning block is fixedly connected with the other end of the operating handle, a positioning bearing is fixedly connected with a side surface of the positioning block, a threaded rod is movablynested in a side surface of the positioning bearing, and an adjusting block is fixedly connected with the end, which penetrates the base and extends to a side surface of the base, of the threaded rod. The electric expander convenient to operate has the advantages that a stop block is connected with the operating handle, accordingly, the locations can be assuredly restrained when the electric expander convenient to operate is used, and slipping phenomena can be prevented when the electric expander is used by operators; the electric expander can be adjusted according to the sizes of the hands of the operators, and accordingly utilization effects of the electric expander can be improved.

Description

technical field [0001] The invention relates to the technical field of rescue and disaster relief equipment, in particular to an electric dilator that is easy to operate. Background technique [0002] The expander is the most powerful expansion, tearing and pulling function among emergency rescue tools, which can carry out high-load rescue operations, and can be used to move and lift obstacles, pry open gaps and expand into channels, and deform metal structures. Tear the steel plate on the surface of the car body. [0003] The existing electric expander is prone to hand slipping under the use of the staff, resulting in the position shift of the expansion site of the device. During its storage, because of the handle on the top, it needs to occupy a certain amount of space during the storage process. storage space, for which a motorized expander that is easy to operate is proposed.

AI Technical Summary

Problems solved by technology

[0004] The invention provides an easy-to-operate electric dilator, which has the advantages of preventing the machine from being unstable due to hand slipping, facilitating the storage of the machine, and reducing the storage space occupied by it. The wear of the rubber sleeve during operation solves the phenomenon of hand slippage after the machine has been used for a period of time, resulting in unstable operation of the machine and a raised handle, which is not convenient for machine storage. The replacement of the rubber sleeve is convenient and reduces its loss. Too many questions
