The utility model discloses a technical scheme lie in: glass protection film drilling special rotary cutter includes: handle of a knife, blade disc and blade, the one end at the handle of a knife is fixed to a side end face of blade disc, the blade is installed on the blade disc, is equipped with central direction point perpendicularly on blade disc and the relative opposite side end face of handle of a knife, the pointed free end of central direction is the toper point portion, and central direction point and the coaxial setting of handle of a knife, sets up at least a set of clamping mechanism who is used for the centre gripping blade on the circumference lateral wall of blade disc, clamping mechanism is including pressing from both sides sword groove and screw mounting hole, screw mounting hole and the intercommunication of pressing from both sides sword groove, the bottom of blade can realize around and/or reciprocate along pressing from both sides sword groove insert direction, and the tight screw in top screw mounting hole back is tight with the blade top, blade and the sharp parallel arrangement of central direction, and the distance of the pointed free end of.
Preferably, the central guide tip is connected with the cutter head through a stepped boss, and the clamping mechanism is located on the periphery of the stepped boss.
Preferably, the maximum outer diameter of the stepped boss is less than 7 mm.
Preferably, the outer diameter of the cutter head is larger than 16 mm.
Preferably, when the number of the clamping mechanisms is two or four, the clamping mechanisms are annularly arrayed around the central guide tip.
The utility model has the advantages that:
1. the utility model utilizes the center guide point to penetrate the protective film for positioning, drives the blade to rotate and cut through the rotating knife handle, thereby realizing hole cutting, and can realize cutting of different apertures through adjusting the position of the blade on the clamping mechanism;
2. compare with traditional blade cutting, the utility model discloses it is convenient to have the aperture to adjust, and the through-hole border rounding off after the cutting is burr-free, and the blade dismouting is changed conveniently, and small handheld convenience is not tired for long-time operation, has saved because of the unqualified extravagant problem of protection film that causes of ordinary blade cutting, has improved the qualification rate of product, and the efficiency of cutting the hole obviously improves moreover.
Description of the drawings:
fig. 1 is a front view of the present invention;
fig. 2 is a side view of the present invention;
fig. 3 is a top view of the present invention;
fig. 4 is an exploded view of the present invention;
wherein: the tool comprises a tool handle 1, a tool pan 2, a blade 3, a center guide tip 4, a stepped boss 5, a clamping mechanism 6, a tool clamping groove 61, a screw mounting hole 62 and a puller screw 63.
The specific implementation mode is as follows:
as shown in fig. 1 to 4, the utility model discloses a special rotary cutter for drilling glass protective film, include: the knife comprises a knife handle 1, a knife disc 2, a blade 3 and a central guide tip 4. The cutter handle 1 is rod-shaped, the section of the cutter head 2 is circular, and the diameter of a through hole needing to be cut is 10mm-15mm, so that the outer diameter of the cutter head 2 needs to be larger than 16cm, preferably 16 cm. One side end face of the cutter head 2 is fixed at one end of the cutter handle 1, and the other end of the cutter handle 1 is a holding end. The end face of the other side, opposite to the cutter handle 1, of the cutter head 2 is vertically provided with a central guide point 4, the central guide point 4 is fixedly connected with the cutter head 2 through a stepped boss 5, and the central guide point 4, the stepped boss 5, the cutter head 2 and the cutter handle 1 are coaxially arranged.
The center guide point 4 is a steel needle and is used for positioning and aligning, one end of the center guide point 4 is a polished rod end, the other end of the center guide point is a free end, the free end is a conical point portion, so that the center guide point 4 can be suitable for different products, a positioning hole used for inserting the center guide point 4 is formed in the center of the stepped boss 5, the positioning hole is in minimum interference fit with the polished rod end of the center guide point 4, and the depth of the center guide point 4 inserted into the positioning hole can be adjusted through external force.
The circumferential side wall of the cutter head 2 is provided with clamping mechanisms 6 for clamping the blades 3, the number of the clamping mechanisms 6 is at least one group or even number more than one group, and the clamping mechanisms 6 are distributed on the periphery of the stepped boss 5.
