Abstract

The invention provides a stone hammer with a telescopic handle. The stone hammer comprises a handle and a hammer head, one end of the handle is fixedly connected with the hammer head, the handle is a telescopic handle and further comprises a hollow socket pipe, an inner handle and a stretching fixing structure, wherein the front end of the inner handle is accommodated in the socket pipe, the rear end of the inner handle is fixedly connected with the hammer head and the inner handle can stretch in the axial direction of the socket pipe; and the stretching fixing structure is arranged at the front end of the inner handle and is used for fixedly maintaining the inner handle in the socket pipe after the inner handle stretches in the axial direction of the socket pipe. Compared with the prior art, the stone hammer provided by the invention has the following advantages: 1, the stone hammer has a small size, occupies a small space, is convenient to transport, use and carry when the handle retracts back; 2, the inner handle is made of rubber and has good shock absorption; and since an elastic steel pipe or steel wire with a thread is arranged at the end of the inner handle in connection with the hammer head, shock and impact on the arm of a user from the handle can be greatly reduced during hammering and the service life of the stone hammer can be prolonged.

Description

technical field [0001] The invention relates to the field of hardware tools, in particular to a masonry hammer with a retractable handle. Background technique [0002] At present, the percussion hammers that people use in rock drilling or hammering stones are generally made up of a hammer head and a wooden handle, and the handle and the hammer head are fixedly connected together, and the length of the handle is fixed. In the process of transportation, use and carrying, it needs to occupy a relatively large space, and it is very inconvenient to use. [0003] In addition, the greater vibration force generated by the hammer head hitting the stone is transmitted to the hands of the people through the handle, so that the people are subject to greater vibration and impact. For this reason, bamboo sheets are bundled up and used as handles to reduce vibration and impact between human hands and handles. And use the hammer operation labor efficiency of this bamboo chip handle to be ...
