[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0016] like Figure 1 , Figure 2 , Figure 3 As shown, this heat dissipation film cutter includes a cutter holder 1, a blade 2, and a bolt 3 for mounting the blade 2 on the cutter holder 1. The cutter holder 1 has a heat dissipation groove 4, and a fixing seat 5 for limiting the blade 2 is provided on the heat dissipation groove 4. The fixing seat 5 has a screw hole 6 for cooperating with the bolt 3. Several heat-conducting plates 7 extending to the bottom of the heat dissipation groove 4 are provided at the lower end of the fixing seat 5. An installation groove 8 for mutually limiting and cooperating with the fixing part is provided below the blade 2.
[0017] When installing the blade 2, align the mounting slot 8 with the fixing seat 5, and simultaneously pass the screw hole 6 through the mounting hole 10, then tighten the bolt 3 until the blade 2 is fully locked.
[0018] Preferably, the front end of the tool holder 1 is provided with a through hole 9 for air circulation. The through hole 9 is connected to the heat dissipation groove 4. The heat on the heat-conducting plate 7 is dissipated through the air circulation, which increases the heat dissipation efficiency.
[0019] Preferably, the fixed base 5 is connected to the tool holder 1 to increase the stability of the fixed base 5 and prevent its position from shifting due to vibration during movement.
[0020] Preferably, the top of the screw hole 6 and the top of the mounting hole 10 are on the same horizontal line, so that the bolt 3 can press down on the screw hole 6 and the blade 2 simultaneously after tightening.
[0021] Preferably, the blade 2 has a mounting hole 10 for engaging with the screw hole 6, and the screw hole 6 engages with the screw rod through a thread.
[0022] Preferably, both the mounting base 5 and the heat-conducting plate 7 are made of metal materials with good thermal conductivity, such as copper. When the blade 2 is heated, the heat will be gradually absorbed by the mounting base 5 and transferred to the heat-conducting plate 7.
[0023] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0024] Although this document frequently uses terms such as tool holder 1, blade 2, bolt 3, heat dissipation groove 4, fixing base 5, screw hole 6, heat-conducting plate 7, mounting groove 8, through hole 9, and mounting hole 10, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
