Description

Cage

technical field

The utility model relates to a fixing frame, which belongs to the technical field of electric tools, in particular to a holding frame which avoids being cut by a saw blade and has the function of collecting dust and chips.

Background technique

In another Chinese patent (authorized notification number CN205799073U) of the applicant, a "dust storage device for miter saws" is disclosed, which includes a storage baffle, and the lower end of the storage baffle is connected to the back of the miter saw baffle. The middle connecting part on the side is fixedly connected, and its upper end is fixed on the outside of the dust outlet of the miter saw. The storage baffle is movable to surround the outside of the lower part of the miter saw blade, and the front of the storage baffle forms a dust storage opening. The utility model can effectively recycle the dust and sawdust passing through the dust outlet of the miter saw and scattered on both sides of the saw blade, can effectively improve the use environment, and protect the health of operators.

Since the lower end of the storage baffle is fixedly connected with the miter saw baffle (the fence), in order to surround the lower part of the saw blade, the storage baffle is usually connected with the fixed guard outside the saw blade at its upper end, while the miter saw baffle (the fence) ) is installed on the base, and parts such as the fixed guard and the saw blade form the saw head and are connected to the base through the workbench. The workbench and the miter saw baffle (rear fence) can be rotated relative to each other. While the fixed guard and the saw blade keep rotating synchronously with the workbench, they can also be opened relative to the workbench by means of the pivot. Therefore, during use, the baffle is stored It is very easy to touch and damage the saw blade; in addition, because the upper end of the storage baffle is fixed outside the dust outlet of the miter saw, the saw blade is directly opposite to the dust outlet, and some larger dust is easy to block the outlet. The dust outlet may accumulate outside the dust outlet, affecting the effect of dust removal and vacuuming.

In the existing manual or electric tools, the cage is mainly used to ensure the cutting direction of the saw blade and the feeding force. For example, the Chinese patent (authorized notification number CN 203636090 U) discloses a "saw blade cage for sawing machines", which includes an outer shell, The wear-resistant alloy block in the shell, the lower part of the outer shell is a groove-shaped opening with the opening downward, and the upper part of the shell is provided with a vertical through hole communicating with the groove-shaped opening. The wear-resistant alloy block is located in the groove-shaped opening, including two A strip-shaped wear-resistant alloy block on the side and a top strip-shaped wear-resistant alloy block; the upper part of the top wear-resistant bar-shaped alloy block is provided with a guide post, which is inserted into the through hole, and the two side wear-resistant strips The outer side of the alloy block is connected to both sides in the slot-shaped opening by screws. The saw blade holder for the sawing machine increases the contact area between the wear-resistant alloy block and the back of the saw blade, reduces the pressure between the back of the saw blade and the alloy block, prolongs the service life of the wear-resistant alloy block, and protects the safety of the shell.

In addition, the cages used in motors, bearings and other components are mainly used to guide or connect moving parts. The above cages do not involve how to prevent the moving parts from being worn, cut, and improve the dust collection effect.
