Cooperate with the clamping block of side corresponding on the second blade and is clamped, the gap and second between the first right cutting and the second right cutting
The clamping block of the corresponding other side cooperates clamping on blade, completes the fixed installation to the second blade jointly, and fixed effect is preferable.
The press block is eccentric toggle, and the flexible restoring organ includes reduction torsion spring and bolt, the folder
Be provided with mounting bracket on head, the bolt is rotatably arranged in the mounting bracket, the eccentric toggle with it is described
Reduction torsion spring it is fixed be set on the bolt, the both ends of the reduction torsion spring are separately connected the bolt and institute
The mounting bracket stated.When reduction torsion spring is in stable state, eccentric toggle is to installation cavity direction pressure positioning part and the first spring
In compressive state, plug-in connection is each passed through corresponding first perforation and the second perforation group with the second snap lock mechanism at this time
After protrude into installation cavity, with the first blade or the second blade mutual cooperation be connected and fixed；When rotating eccentric toggle by external force
Afterwards, eccentric toggle is whole mobile towards the direction far from installation cavity, and the first spring pushes locating piece to move towards the direction far from installation cavity
Dynamic, plug-in connection is deviate from the second snap lock mechanism from installation cavity from inside to outside at this time, and the first blade or the second blade are unclamped
To take out, dismount very convenient；Wherein, other conventional RESET structures can also be used in press block and flexible restoring organ, such as push up
Briquetting is key, and flexible restoring organ is the reset spring being arranged between key and collet, and reset spring is in stable state
When direction pressure positioning pin from key to installation cavity and locating piece, reset spring can be tension spring or pressure spring, by being set on collet
Corresponding mechanism is set to be coupled.
Compared with the prior art, the advantages of the present invention are as follows when flexible restoring organ is located at stable state, press block to
Cavity direction pressure positioning part is installed and the first spring is in compressive state, plug-in connection and the second snap lock mechanism are distinguished at this time
It is protruded into installation cavity after corresponding first perforation and the second perforation group, cooperates and connect with the first blade or the second blade
It is fixed；When making to press direction movement of the block towards separate installation cavity by external force, the first spring pushes locating piece towards far from installation
The direction of chamber is mobile, and plug-in connection is deviate from the second snap lock mechanism from installation cavity from inside to outside at this time, by the first blade or the
Two blades unclamp to take out, and dismounting is very convenient, and two kinds of tools can be installed as needed on a kind of cutting tool by realizing
There is the function of the blade of different tail structures, overall structure is simple, and it is easy to use, it can effectively reduce and carry space, actually answer
In mountable curve saw blade and reciprocal saw blade both be frequently necessary to replace the blade used in same operating environment.
