Modified structure of 360-degree expansion guard cover

Abstract

The invention relates to a modified structure of a 360-degree expansion guard cover. The modified structure comprises a plurality of frames and is formed by sequentially stacking the frames from big ones to small ones. Each frame is composed of one or two opposing boards. A perpendicularly extending sleeve is arranged on one side of the center of each board. The sleeves are sleeved according to the diameter sequence, so that one upper board exactly covers the hollow sleeve of the board below, holding space is formed between the sleeves of the two boards, and at least one elastic return component is disposed in each holding space. Therefore, tool heads (as for cutting, positioning and the like) or other moving parts can be disposed in the hollow sleeves, the modified structure can move quickly in multiple directions and is protective.

Description

technical field [0001] The present invention is an improved structure of a 360-degree telescopic protective cover, especially a protective cover formed by sequentially stacking and combining multiple frames from large to small, which can move quickly in multiple directions. Background technique [0002] Nowadays, in order to cope with mass and rapid production, various scraps are produced during processing. Therefore, in order to prevent the scraps from falling into the working tools and affect the operation and safety considerations, there are various protective covers to greatly extend the use of the tools. Life, processing efficiency and operation safety; common protective cover devices can be divided into two types: telescopic and fixed. Among them, the telescopic structure can save space, and it is common to provide protection for the moving and processing of working tools. There are also Combining multiple retractable protective covers to provide multiple directions of...

[0002] Nowadays, in order to cope with mass and rapid production, various scraps are produced during processing. Therefore, in order to prevent the scraps from falling into the working tools and affect the operation and safety considerations, there are various protective covers to greatly extend the use of the tools. Life, processing efficiency and operation safety; common protective cover devices can be divided into two types: telescopic and fixed. Among them, the telescopic structure can save space, and it is common to provide protection for the moving and processing of working tools. There are also Combining multiple retractable protective covers to provide multiple directions of movement, it is provided with retractable protective covers at the front and rear of the working tool (tool head, etc.), and then provided with retractable protective covers at the left and right, so it The design structure and configuration are more complex, and in terms of movement, it needs to move horizontally, then vertically, or vertically, then horizontally to reach a polar coordinate point, so the movement is relatively simple, so the movement efficiency is not good , so there is still room for improvement and innovation
