Sliding, the side that the cutter broach shell is not in contact with the slot that the fixing seat opens up is slightly above the installation of the fixing seat
Contact surface, the cutter broach shell may be mounted to that work fixed frame by the mounting screw of the mounting hole in the fixing seat
On.
The program is to carry out cutter as fixed cutting tool using instead making cutter lose itself and convenient use
Characteristic, and blade is still exposed, the caused risk too fast for cutting speed does not have precautionary measures.
Utility model content
The utility model is intended to provide a kind of safety beauty that rate limitation can be able to carry out when toolsmith makees excessive velocities
Work knife is provided with insert pocket on the blade including shell, blade support, the buckle with spring, blade, described
The blade block matched with insert pocket, the buckle and blade support is provided on blade support to connect by spring slide
It connects, the sliding groove for being provided with and being clasped on the shell, so that buckle can drive blade support fortune along sliding groove
Dynamic, the limiting tooth for being additionally provided with and being clasped in shell, shell one end is provided with the edge of a knife that goes out with blades fit, and described is outer
Be additionally provided with speed-limiting device on shell, the speed-limiting device includes contact roller, call wire and cam, the contact roller with
Shell rotation connection, call wire are connected with contact roller axis, and call wire is connected with camshaft, and cam is arranged on the shell, cam
Flange is located at below buckle lower end, and on the shell, adjustment axle position is provided on camming rim the setting of adjustment axis in the middle part of adjustment line
Centrifugal-block, centrifugal-block and camming rim elastic connection.Blade and contact roller are all in contact with working face when work, contact roller
As the cutter of blade rotates, call wire is driven, call wire band moving cam rotates.When excessive velocities, on cam from
Heart block is greater than the elastic force and separate cam axle center that elastic connection is brought because of required centripetal force, so that centrifugal-block hit card is detained
End, after buckle is detached from limiting tooth, blade is pushed back the safe retrieving that interior of shell completes blade by the pressure on blade.
Preferably, being additionally provided with length adjuster on the shell, length adjuster is installed inside the housing,
Length adjuster and call wire cooperate, and length adjuster includes shifting axle, fixing axle and adjustment spring, and fixing axle setting exists
In shell, adjustment spring one end is connected with fixing axle, and the adjustment spring other end is connected with shifting axle, and shifting axle and shell sliding connect
It connects.Length adjuster can be such that the use length of call wire changes, so that cam is not limited to a position and with bayonet
Lower end is mobile, that is to say, that cam may be mounted on blade support.
Preferably, the shifting axle is slidably connected on adjustment spring direction with shell.
Preferably, being additionally provided with anti-slip protrusion on the shell, anti-slip protrusion setting is held on the shell and lower end.
Preferably, being additionally provided with the link for hanging up storage on the shell other end.
In conclusion the utility model has the advantages that can be able to carry out speed limit when toolsmith makees excessive velocities
System.
