[0020] Example 1: Please refer to Figure 1 - Figure 3 A corner-cutting device for processing adhesive strips includes a working panel 1 and support legs 2 fixedly installed on both sides of the lower end of the working panel 1. A limit component 3 is provided at the upper end of the working panel 1. The limit component 3 includes a fixed block 31 fixedly installed at the upper end of the working panel 1. A connecting groove 32 is provided on both sides of the fixed block 31. An installation groove 34 is provided on both sides of the interior of the fixed block 31. A connecting plate 35 is fixedly installed at the upper and lower ends of the installation groove 34. A movable block 36 is slidably installed on the connecting plate 35. A connecting rod 38 is fixedly installed on the upper and lower side walls of the movable block 36. A spring 37 is fixedly installed between the inner wall of the movable block 36 and the inner wall of the installation groove 34. A rotating wheel 39 is rotatably installed between the two connecting rods 38. A cutting component 4 is provided at the upper end of the fixed block 31.

[0021] In this embodiment: When using the device for cutting the corners of the adhesive strip, the adhesive strip to be cut can be inserted into the interior of the fixing block 31 along the connecting groove 32 opened on the fixing block 31. When the adhesive strip is inserted into the connecting groove 32, it contacts the rotating wheels 39 set on both sides. Under the action of the spring 37, the rotating wheels 39 set on both sides are pushed towards the center, which can fix and clamp the adhesive strip inserted into the connecting groove 32. Since the rotating wheels 39 are set at both the upper and lower ends inside the connecting groove 32, the rotating wheels 39 can change their contact range with the side of the adhesive strip according to the shape of the adhesive strip. The setting of the rotating wheels 39 that can slide left and right makes it suitable for fixing and clamping adhesive strips of various shapes when clamping and fixing the adhesive strip. It can maintain the fixed clamping of the adhesive strip when cutting different adhesive strips, which is convenient for subsequent cutting.

[0022] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 2 - Figure 4 The fixing block 31 has a cutting groove 33. The cutting component 4 includes a fixing frame 41 fixedly installed on the upper end of the fixing block 31. A cutter 42 is slidably connected to the fixing frame 41. The cutter 42 is slidably connected in the cutting groove 33. The cutter 42 can slide along the fixing frame 41 through the obliquely set cutter 42 to cut the rubber strip in the fixing block 31.

[0023] The work panel 1 has scale bars 5 fixedly installed on both sides of one side. The upper side of the work panel 1 has a slide groove 11, and a movable component 6 is installed in the slide groove 11. The scale bars 5 can be used to observe the length of the extended rubber strip.

[0024] The active component 6 includes a slider 61 that is slidably connected in the slide groove 11. Each slider 61 has a stop plate 62 fixedly installed at its upper end. When the rubber strip slides along the connecting groove 32, it can stop against the stop plate 62.

[0025] The slider 61 is fixedly mounted with a slide rod 63 on its side, and the slide groove 11 has a slot 12 on its side, in which the slide rod 63 is slidably connected.

[0027] In this embodiment: When using this device for corner cutting of adhesive strips, the movement distance of the abutment plate 62 can be controlled by pulling the slider 61 and the abutment plate 62. The distance between the abutment plate 62 and the fixing block 31 can be observed through the scale strip 5 on the side of the abutment plate 62. Adjust it to the required length of the adhesive strip. At this time, the slider 61 and the abutment plate 62 can be fixed and limited by the cooperation of the pin and the slot 64 on the slide rod 63. After the fixing is completed, the adhesive strip to be cut can be inserted into the interior of the fixing block 31 along the connecting groove 32. During the process of pushing the adhesive strip... One end of the adhesive strip is pressed against the side wall of the abutment plate 62. At this time, the cutter 42 can be pushed diagonally downward along the fixed frame 41 and slid downward along the cutting groove 33 to cut the adhesive strip. After the cutting is completed, the pin can be pulled out. At this time, under the action of the second spring 66, the slider 61 can be automatically pushed and slid to the position of contacting the side of the fixed block 31. When using this device, the cutting length of the adhesive strip can be adjusted. The extension length of the adhesive strip can be adjusted by pulling the slider 61 and the abutment plate 62. After the cutting is completed, releasing the slider 61 and the abutment plate 62 will return them to their original positions.
