[0021] The first lifting seat 2 is connected to the fixed seat 1 via a guide mechanism that can guide in the up and down directions.

[0022] In a preferred embodiment of the present invention, the driver 4 is a cylinder, and the output shaft of the cylinder is connected to the second lifting seat 3. The guide mechanism includes a guide post 71 fixed to the first lifting seat 2, and a guide sleeve 72 fixed to the fixed seat 1 and slidably matched with the guide post 71. The guide post 71 and the first lifting seat 2 can be connected by screw connection, welding, etc., and the guide sleeve 72 and the fixed seat 1 can be connected and fixed by screw connection, welding, etc.

[0023] In some embodiments of the present invention, the guide mechanism may also adopt other structural forms, for example, the guide post 71 is fixed on the fixed seat 1, and the guide sleeve 72 is fixed on the first lifting seat 2. The driver 4 may also adopt other structural forms, such as an electric push rod.

[0024] Furthermore, a guide hole 21 is provided on the first lifting seat 2, and the cutting assembly includes a handle bar 81 and a movable blade 82 fixed to the lower end of the handle bar 81, the blade of the movable blade 82 is located at its lower edge, and the blade of the fixed knife 101 is located at its upper edge. The movable blade 82 and the handle bar 81, and the handle bar 81 and the second lifting seat 3 can be connected and fixed by means of screw connection, welding, etc. The handle bar 81 is slidably matched with the guide hole 21, and the upper end of the handle bar 81 is fixed to the second lifting seat 3. With such a design, the movable blade 82 can be guided so that the movable blade 82 can move up and down stably.

[0025] Reference Figure 2 The pressing member 6 is rod-shaped, and a groove 61 for pressing the workpiece is provided at the lower end of the pressing member 6.

[0026] Reference Figure 1 The first lifting seat 2 is provided with a through hole 22 which passes through the first and second lifting seats 3. The limiting device includes a bolt 9 which passes through the through hole 22. The head of the bolt 9 is located at the lower end thereof. The tail of the bolt 9 is screwed to the second lifting seat 3. The first lifting seat 2 can abut against the upper surface of the head of the bolt 9 to limit the maximum distance between the first lifting seat 2 and the second lifting seat 3. The elastic member 5 is a compression spring sleeved on the bolt 9. The upper end of the compression spring abuts against the second lifting seat 3, and the lower end of the compression spring abuts against the first lifting seat 2.

[0027] The working principle of the present invention is: the initial state of the shearing device is as follows: Figure 1 As shown, at this time, the lower edge of the movable knife assembly is slightly higher than the lower end of the top pressure piece 6. When the LED light strip is conveyed onto the workbench 10, the driver 4 works to push the second lifting seat 3 and the first lifting seat 2 to move downward together. When the top pressure piece 6 presses the LED light strip, the first lifting seat 2 no longer moves downward, and then the second lifting seat 3 and the movable knife assembly continue to move downward, and cooperate with the fixed movable blade to cut the LED light strip. The state at this time is as shown in FIG. Figure 3 As shown, the elastic member 5 is compressed during this process. Finally, the driver 4 drives the second lifting seat 3 to reset upward. During this process, the elastic member 5 will gradually recover elastically. When the head of the bolt 9 used as a limiting device abuts against the first lifting seat 2, the first lifting seat 2 will move upward together with the second lifting seat 3 until the shearing device returns to its initial position.

[0028] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or directly or indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
