The following is only the preferred embodiment of the utility model, and does not limit the protection scope of the utility model. For an example, see.
The planer tool holder shown in figure 1 includes a tool holder 2 for supporting the blade 1, a cutter pressing cover 3 for covering the blade 1 and a screw 4 for fixedly connecting the cutter pressing cover 3 and the blade 1. The first connector for connecting the blade 1 is movably arranged on the tool holder 2, and the tool holder 2 is connected with the return spring 6. The tool rest 2 and the gland 3 are connected with the tool rest 2 through a second connector, and the gland 3 is provided with a long and narrow hole 3 1 for the screw 4 to move. The screw 4 passes through the long and narrow hole 3 1 and is connected with the screw hole 1 2 on the blade1,and the nut of the screw 4 is pressed on the gland 3. In this embodiment, the elongated hole 3 1 is a waist-shaped hole. The first connector includes a protrusion 5 1 clamped in the blade connection groove1. In this embodiment, there are two protrusions 5 1, which are connected by a cross bar 52, and the return spring 6 is connected between the cross bar 52 and the tool holder 2. The crossbar 52 is connected to a handle 53 exposed through the tool holder 2. The second connector includes a positioning block 8 1 provided on the tool holder cover 3 and a groove 82 provided on the tool holder 2. The tool rest 2 is a quadrangular frame, the stopper 7 is a boss arranged on the upper frame of the tool rest 2, and the return spring 6 is pushed between the cross bar 52 and the lower frame of the tool rest 2. It can be understood that the return spring 6 can also be arranged between the cross bar 52 and the upper frame of the tool holder 2. The return spring 6 is sleeved on the screw 9, which is connected between the upper and lower frames of the tool rest 2. The working principle of this embodiment is that the convex block is stuck in the blade connecting groove, so that the blade is mounted upward on the tool holder, and a return spring is arranged between the cross bar and the lower frame of the tool holder, and the return spring automatically pushes the blade onto the blade and abuts against the stopper on the upper frame of the tool holder, thus ensuring that the exposed position of the blade remains unchanged, and then the blade is fixedly connected with the knife cover covered on it by screws, so that the blade is fixed in a well-aligned position relative to the knife cover. After that, remove the tool rest and install the aligned blade and cover on the planer for later use. In this embodiment, when adjusting the cutter, it is not necessary to manually push the cutter against the stopper, and the alignment of the cutter blades can be automatically realized through the action of the return spring, so that the operation is simple and convenient; Moreover, since the first connector is arranged between the blade and the tool holder, and the second connector is arranged between the cutter pressing cover and the tool holder, the blade and the cutter pressing cover are not easy to slide relative to the tool holder.
Claim 1. The tool rest of the planer comprises a tool rest (2) supporting the blade (1), a cutter pressing cover (3) covering the blade (1) and a screw (4) for fixedly connecting the cutter pressing cover (3) and the blade (1), and the cutter pressing cover (3) is connected with the tool rest (2) through a second connector.
2. The planer tool holder according to claim 1, characterized in that the first connecting piece comprises a protrusion (5 1) clamped in the blade connecting groove (1 1), and the protrusion (5 1) passes through a cross bar (52
3. The planer tool holder according to claim 1 or 2, characterized in that the second connector is a groove (82) and a positioning block (8 1) arranged between the tool holder cover (3) and the tool holder (2).
4. The planer tool holder according to claim 3, characterized in that the tool holder (2) is a quadrangular frame, the stopper (7) is a boss arranged on the upper frame of the tool holder (2), and the return spring (6) is pushed between the cross bar (52) and the lower frame of the tool holder (2).
5. The planer tool holder according to claim 4, characterized in that the cross bar (52) is connected with a handle (53) exposed through the tool holder (2).
6. The planer tool holder according to claim 5, characterized in that the return spring (6) is sleeved on the screw (9), and the screw (9) is connected between the upper and lower frames of the tool holder (2).
The utility model discloses a planer tool holder, which comprises a tool holder for supporting a blade, a cutter pressing cover for covering the blade, and a screw for fixedly connecting the cutter pressing cover and the blade. A first connector for connecting the blade is movably arranged on the tool holder, and the first connector is connected with a return spring, and a limiting piece is arranged on the tool holder, and the return spring pushes the blade to the blade edge and abuts against the limiting piece; The tool holder is connected with the tool holder through a second connecting piece, and the tool holder is provided with a long and narrow hole for the screw to move, and the screw passes through the long and narrow hole and is in threaded connection with the blade, and the nut of the screw is pressed on the tool holder. The utility model provides an electric planer tool rest, which has the characteristics of convenient automatic tool alignment and difficult sliding of the blade and the fixing piece. X
