In the figure: 1 base, 11 partition, 12 gap, 13 guide column, 2 knife holder, 21 groove, 22 push block, 23 blade, 3 end cover, 31 handle, 4 tape, 41 tape cloth, 5 fixed shaft , 51 bearings, 52 fixed barrels, 53 movable shafts, 531 tops, 54 toggle rods.

Detailed ways

As shown in Figures 1 to 4, the present invention includes a base 1, a partition 11, a guide column 13, a tool holder 2, a push block 22, a blade 23, an end cover 3, a fixed shaft 5, a bearing 51, a fixed cylinder 52, The movable shaft 53 and the toggle lever 54 will be described below in conjunction with the accompanying drawings.

As shown in Figures 5 to 8, the base 1 is a cylindrical plastic part, and a circular partition 11 is fixed in the inner cavity of the base. The partition is a plastic part, and the partition can be integrally formed with the base. . The partition divides the inner cavity of the base into two independent tape placement cavities, and the base is provided with two notches 12 corresponding to the two tape placement cavities respectively, and the notches run through the corresponding sides of the base. A guide post 13 is vertically fixed at the edge of the partition, and there are two guide posts, which are respectively fixed on both sides of the partition. The two guide posts can be arranged symmetrically, or on different circumferences on the dividing plate. Two fixed shafts 5 are fixed at the center of the partition. The fixed shafts are cylindrical plastic parts. The two fixed shafts are arranged symmetrically with respect to the partition. The fixed shafts can be integrally formed with the partition. As shown in Figure 10, a bearing 51 is respectively fixed on each fixed shaft, and three fixed cylinders 52 are evenly arranged on the outer wall of the bearing along the circumferential direction. radial setting. A movable shaft 53 is slidably installed in the inner cavity of each fixed cylinder. The movable shaft is a plastic round rod. A spring is arranged between the movable shaft and the fixed cylinder. Under the action of the spring, most of the movable shaft is placed in the fixed cylinder. At this time, the total length of the fixed cylinder and the movable shaft is the largest. Pressing the movable shaft into the inner chamber of the fixed cylinder can make the movable shaft slide in the inner chamber of the fixed cylinder. As shown in FIG. 11 , in order to drive the sliding of the movable shaft, a toggle rod 54 is arranged radially on the outer wall of the movable shaft, and the sliding of the movable shaft in the fixed cylinder is realized by stirring the toggle rod. One end of the movable shaft placed outside the fixed cylinder is the top 531, which is conical. The setting of the tip is convenient for clamping and fixing the tape. Three blind holes can be pierced on the inner wall of the tape, and the tip of the tip is placed in the blind hole. The fixed shaft, bearing, fixed cylinder, movable shaft, spring and toggle rod constitute Clamping and rotating assembly.

As shown in Figures 5 to 7, a knife rest 2 is provided outside the base, the knife rest is an arc-shaped plastic part, the knife rest can be integrally formed with the base, and the knife rest is next to the two gaps. Two rectangular grooves 21 are arranged on the side of the knife holder, and a blade 23 is placed in each groove. As shown in Figure 12, the active end of the blade is zigzag, which can facilitate the cutting of the adhesive tape. As shown in Figure 13, the blade can also be a right-angled trapezoid, and the hypotenuse of the blade is the active end of the blade. Two push blocks 22 are arranged on the top of the tool holder, and the two push blocks are plastic parts, and the bottoms of the two push blocks are fixedly connected with the two blades respectively, and the blade can be released from the groove or the blade can be pushed into the groove by pushing the push block. in the slot.

As shown in Figure 1, an end cap 3 is threadedly installed at the two ends of the base respectively, and the end cap is a circular plastic part. The inner diameters are the same size. The function of the end cap is to seal the inner cavity of the base. For the convenience of handling the end cap, a handle 31 is provided at the center of the end cap.

When in use, the end cover can be removed first, and then the toggle lever is moved inward, so that the movable shaft on the fixed cylinder moves towards the center of the base, and then the adhesive tape 4 is put on the outside of the three movable shafts, and the dial is loosened. After moving the rod, under the action of the spring, the top of the movable shaft is pressed against the inner wall of the adhesive tape and clamped. At this point, the tape can rotate with the bearing. Then the adhesive tape is uncovered, and the adhesive tape cloth 41 that is uncovered is pulled out through the gap, as shown in Figure 9, the adhesive-free side of the adhesive tape is in contact with the guide post and rubs against each other, the requirement for the guide post is that the surface is smooth, so It can reduce the friction between the tape cloth and the guide column. Push the push block so that the blade is exposed, and then pull one end of the tape cloth close to the blade to cut the tape cloth.

When the cutter is in a non-working state, the blades are placed in the knife holder, which will not pose a threat to children. The tape is sealed in the cavity enclosed by the end cap and the base, which facilitates the placement of the tape. After each use of the tape, one end of the tape cloth can be pasted on the outer wall of the base for easy access next time.

In order to increase the aesthetics and prevent the edges of the knife holder from scratching children's fingers, the edges of the knife holder are rounded. The partition divides the inner cavity of the base into two parts, and two tapes can be placed in the inner cavity of the base, and the width of the adhesive tapes can be different to meet different needs.
