By rotating the adjustment rod 34, the linking rod 35 can be moved along the second direction D2, and the height H of the end surface of the pusher 31 protruding from the cutter holder 20 can be adjusted. In other embodiments, the pusher or the linking rod can be connected to the main body by other methods, such as a combination of a spring and a locking mechanism, an eccentric shaft mechanism, or a multi-stage snap-fit ​​structure, which can achieve the effect of adjusting or positioning the pusher.

[0011] In detail, the main body 10 further includes an accommodating portion 13, which includes an accommodating groove 131 extending along the second direction D2, a first opening 132, and a second opening 133. The adjusting rod 34 and the linking rod 35 are accommodated in the accommodating groove 131. The first opening 132 and the second opening 133 are respectively connected to the accommodating groove 131 and are located on opposite sides of the main body 10. The adjusting rod 34 is partially exposed to the first opening 132 and can be operated externally. The pusher 31 protrudes from the second opening 133. Preferably, the portion of the adjusting rod 34 exposed to the first opening 132 is further provided with a plurality of ratchet teeth 341 distributed along the threads of the screw structure, and the ratchet teeth 341 partially protrude from the first opening 132 to provide an anti-skid effect for facilitating rotation of the adjusting rod 34, as shown in FIG. 3 .

[0012] The accommodating portion 13 further includes a groove peripheral wall 134 that defines the accommodating groove 131, and a cover 135 that covers the groove peripheral wall 134. One of the groove peripheral wall 134 and the cover 135 has at least one engaging recess 134a, and the other has at least one engaging protrusion 135a that can be engaged with the at least one engaging recess 134a. As shown in FIG. 5 , the adjustment rod 34 and the linking rod 35 can be easily assembled. Specifically, the accommodating groove 131 includes a first groove 131a that accommodates the adjustment rod 34 and a second groove 131b that accommodates the linking rod 35. The first groove 131a has a cross-sectional profile that at least partially corresponds to the adjustment rod 34, and the second groove 131b communicates with the first groove 131a and has a cross-sectional profile that at least partially corresponds to the linking rod 35. The second opening 133 is formed in the cover 135 and has a cross-sectional profile corresponding to the linking rod 35, allowing the linking rod 35 to move smoothly without distortion. The linking rod 35 is further provided with a contact protrusion 351 on the outer circumferential surface thereof, which abuts against the cover 135 in the second direction D2 to prevent it from coming loose. Two channels 14 are defined between the opposing side walls of the groove peripheral wall 134 and the main body 10, and the tape piece 201 extends through each channel 14. Each opposing side wall of the groove peripheral wall 134 is provided with an arc-shaped chamfer 134b adjacent to the positioning unit 11 for abutting against the tape piece 201, thereby guiding the tape piece 201 to avoid wrinkles and the like. In use, the operator can pass the tape piece 201 through one of the channels 14 as needed, which can be applied whether the fixing surface 4 is located on the left or right side of the work surface 3.

[0013] The tape dispenser 1 further includes a spacer 40, and the cutter holder 20 includes a cutting portion 21 for cutting the tape piece 201. The spacer 40 protrudes from the cutting portion 21 in the first direction D1 and is used to abut against the work surface 3. The spacer 40 can be positioned toward the first side S1 or the second side S2 of the cutter holder 20. This allows the cutting portion 21 and the work surface 3 to maintain a gap therebetween, and the positioning direction of the spacer 40 can be adjusted as needed. Specifically, the cutter holder 20 is provided with two first position restriction portions 22 and two pressing surfaces 23 provided on the first side S1 and the second side S2, respectively. The spacer 40 is provided on the cutter holder 20 so as to be releasable by a positioning member 50, and includes two second position restriction portions 41. When the spacer 40 is positioned toward the first side S1, as shown in Fig. 7, the first position restriction portion 22 adjacent to the first side S1 is locked with the second position restriction portion 41, and the spacer 40 does not protrude from one of the pressing surfaces 23 at the second side S2, and when the spacer 40 is positioned toward the second side S2, as shown in Fig. 8, the first position restriction portion 22 adjacent to the second side S2 is locked with the second position restriction portion 41, and the spacer 40 does not protrude from the other of the pressing surfaces 23 at the first side S1. This provides a two-way positioning function, is suitable for operation in various directions, and improves flexibility in use.

[0014] In this embodiment, the positioning member 50 is a screw, and each of the first position restricting portions 22 includes an arc-shaped convex surface 221 and a concave notch 222. Each of the second position restricting portions 41 includes an arc-shaped concave surface 411 whose shape corresponds to the arc-shaped convex surface 221 and a convex angle 412 whose shape corresponds to the concave notch 222, thereby providing excellent locking stability. The spacer 40 further includes an arc-shaped end surface 42 away from the opening 12, which allows it to move smoothly along the fixing surface 4 and prevents it from scratching.

[0015] The receiving portion 13 includes a first abutment surface 136, the cutter holder 20 is detachably mounted on the main body 10, and includes a second abutment surface 24, the first abutment surface 136 and the second abutment surface 24 having corresponding shapes that abut against each other in the first direction D1, thereby preventing the cutter holder 20 from being distorted when subjected to force during use and improving structural stability. Specifically, the main body 10 further includes a boss 15 extending along the second direction D2, the boss 15 having a non-circular cross-sectional profile, the cutter holder 20 fitted onto the boss 15 so as not to rotate relative to the boss 15, and sandwiched and abutted between the main body 10 and the spacer 40, so that the cutter holder 20 can be replaced according to the width of the tape piece 201 and can still be used in conjunction with the spacer 40.

[0016] The arrangement unit 11 includes a plurality of locking arms 111 spaced apart around the rotation axis direction R and a plurality of rotating wheels 112, 112a that can be fitted around one another, one of which is rotatably fitted around the outer periphery of the locking arms 111, and one side of which in the rotation axis direction R interferes with and engages with the other rotating wheel 112a. This allows for the application and removal of the rotating wheel 112a with a larger diameter as needed when the outer fitting holes of the tape roll 2 have different inner diameters, making it possible to use tapes of various specifications without the need for an additional adapter, thereby improving the integration and versatility of the tool.
