[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 , a tape cutting device, comprising a cutting seat 1, a cutting blade 2 is rotatably mounted on the top of one end of the cutting seat 1, gears 3 are fixedly mounted on both ends of the cutting blade 2, racks 4 are arranged at the bottom of the two gears 3, the racks 4 are meshed with the gears 3, the two gears 3 and the two racks 4 are arranged inside the cutting seat 1, a connecting rod 5 is fixedly connected between one ends of the two racks 4, and the connecting rod 5 is slidably mounted on the cutting seat 1; when the device is used to cut the tape, the cutting of the tape is completed by the cutting blade 2, but the cutting blade 2 is arranged vertically upward, and when the user accidentally touches the cutting blade 2, it may cause harm to the user, so when the device is not in use, the connecting rod 5 can be pushed, and the connecting rod 5 drives the rack 4 to move, and drives the gear 3 to rotate, so that the cutting blade 2 is changed from a vertical upward state to a vertical downward state, so that the cutting blade 2 is hidden at the blade tip to avoid accidental touch by the user.

[0025] As the preferred technical solution of this embodiment, a block 6 is slidably installed at one end of the cutting seat 1 close to the connecting rod 5, and the block 6 is adapted to the connecting rod 5. A spring 7 is fixedly installed at the bottom of the block 6, and the bottom end of the spring 7 is fixedly connected to the inside of the cutting seat 1; when using the cutting blade 2, the connecting rod 5 is pulled, and the rack 4 is driven to move through the connecting rod 5, so that the gear 3 rotates, and the rotation of the gear 3 drives the cutting blade 2 to rotate, so that the blade of the cutting blade 2 is set vertically upward, which is convenient for cutting the tape. When the connecting rod 5 moves to the position of the block 6, since the side wall where the block 6 contacts the connecting rod 5 is set as an inclined surface, the connecting rod 5 presses down on the block 6 along the inclined surface. When the connecting rod 5 enters the top slot of the block 6, the spring 7 lifts the block 6, so that the connecting rod 5 engages with the block 6, and fixes the connecting rod 5, the rack 4, and the gear 3.

[0026] As the preferred technical solution of this embodiment, a paddle 9 is fixedly installed on the side wall of the block 6, one end of the paddle 9 passes through the side wall of the cutting seat 1 and slides with the cutting seat 1, and the ends of the two racks 4 away from the connecting rod 5 are fixedly connected with a tension spring 8, and the ends of the two tension springs 8 away from the rack 4 are fixedly connected to the inside of the cutting seat 1; when the cutting blade 2 needs to be retracted, the paddle 9 is pushed downward, and the block 6 is pressed down by the paddle 9, so that the connecting rod 5 and the block 6 are disengaged from each other. After the connecting rod 5 is disengaged from the block 6, the rack 4 is pulled back under the action of the tension spring 8, and when the rack 4 moves, it drives the gear 3 meshing with the rack 4 to rotate, so that the cutting blade 2 is retracted.

[0027] As a preferred technical solution of this embodiment, a support column 11 is provided through the top of one end of the cutting seat 1 away from the blocking block 6, and one end of the support column 11 that passes through the side wall of the cutting seat 1 is threadedly connected with a locking nut 12, and an adapter block 13 is sleeved on the support column 11, and the adapter block 13 is arranged inside the cutting seat 1; during the use of this device, the support column 11 and the adapter block 13 cooperate with the tape to complete the installation of the tape, and the size of the adapter block 13 can be changed according to the size of the inner hole of the installed tape, so as to adapt to various types of tapes.
