Moreover, the locking block locks the clamped materials under the action of the elastic force of the spring, and the redundant locking force of the cam can be converted into the elastic force to be stored in the spring, so that the materials are always under the action of the continuous locking force.
The structure improvement aiming at the limiting side can be that a boss which is embedded into the long slotted hole and used for moving linearly along the direction of the long slotted hole is arranged at the inner side of the limiting block; the adjusting shaft sequentially penetrates through the limiting handle, the sliding block and the horizontal long slotted hole and then is axially connected with the limiting block; the boss is embedded into the long slotted hole of the main board, so that the limiting block always runs along a straight line and is limited, and the rotation of the limiting block can be realized without the influence of material bounce.
The inner side of the sliding block is provided with a boss which is embedded into the long slotted hole and used for linearly moving along the direction of the long slotted hole; and a groove and tenon meshing mechanism is correspondingly arranged between the mutual contact surfaces of the limiting handle and the sliding block.
Preferably, an arc-shaped concave-convex surface is correspondingly arranged between the limiting handle and the sliding block; when the fixed shaft of the limiting handle rotates, the arc-shaped convex surface and the arc-shaped concave surface are mutually locked in a staggered mode or are loosely occluded.
In order to realize the operation area of an operator far away from the cutter, the handle is fixed on the main board through screws, and the handle, the limiting block and the fixed seat are respectively positioned on two sides of the main board. Change the handle into two-way support, when being favorable to operator's hand to exert oneself and promote the mainboard, the working area of milling cutter can be kept away from to its both hands.
