Handheld type slotting machine

Abstract

The invention discloses a handheld type slotting machine. The handheld type slotting machine comprises a machine body (1), a middle cover (3), a transmission box body (5) and a cutting blade (11), wherein a fixed protective cover and a movable protective cover (10) are arranged on the transmission box body (5); the fixed protective cover is formed by mutually fixing a fixed cover base (6) and a fixed cover lid (7); the movable protective cover (10) comprises a movable cover (9), a guide base (20), a return spring (18); the movable cover (9) is arranged on the fixed cover base (6); the return spring (18) is connected between the movable cover (9) and the fixed cover base (6); the movable cover (9) can automatically open and close relative to the fixed cover base (6); the guide base (20) isfixedly arranged on the movable cover (9), and is at least equipped with a group of guide wheels (19); an arc-shaped slot (15) is formed in the fixed cover (7); and the movable cover (9) is provided with a locking knob (12) which is used for locking or loosening between the movable cover (9) and the fixed cover lid (7). The structure is adopted, so that the handheld type slotting machine has the advantages of being simple and reasonable in structure, convenient in operation and use, free of a dead corner for slotting, high in working efficiency, obviously improved in working environment, and the like.

Description

technical field [0001] The invention relates to a slotting tool, in particular to a hand-held slotting machine used for laying ground and wall pipelines. Background technique [0002] With the development of society and the advancement of science and technology, people have higher and higher requirements for office conditions and home furnishing. In the process of office space and home interior decoration, it is necessary to carry out strong and weak current wiring, as well as water and gas pipeline laying; At present, the most effective method for strong and weak current wiring and pipeline laying is to use a hand-held slotting machine to slot on the ground or walls. Due to the high slotting efficiency of the slotting machine, its working efficiency is several times or even ten times that of manual slotting. Several times, so it is deeply loved by the industry. However, the existing hand-held slotting machines have the following problems in use: one is that they can only s...

AI Technical Summary

Problems solved by technology

However, the existing hand-held slotting machines have the following problems during use: one is that they can only slot on the same wall or ground due to the limitation of the cutting saw blade fixed guard, and there is a slotting dead angle when slotting at the corner, Corner slotting still needs to be done manually, which directly affects the work efficiency of wiring or piping

The second is that it can only be grooved on a relatively flat ground or cover, and continuous grooves cannot be made on occasions that are uneven or have obstacles such as cement blocks.

The third is that due to the dust flying, sand splashing and harsh working conditions during the slotting and cutting process, although certain protective measures have been taken, they have not been completely solved and need to be further improved; for this reason, many manufacturers and people of insight have carried out has been developed and developed, but so far no better products have come out
