[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 3 In an embodiment of the utility model, a portable three-dimensional scanner includes a scanner body 1, a handle 2 is fixed to the outer wall of the scanner body 1, the handle 2 is used to provide support for the scanner body 1, and a transmission mechanism 3 is arranged on the handle 2, and the transmission mechanism 3 is used to increase the connection force during the contact process between the hand and the handle 2;

[0030] The transmission mechanism 3 includes a transmission unit and a limit unit;

[0031] The transmission unit is used to adjust the contact distance between the clamping rod 301 and the hand;

[0032] The limiting unit is used to limit the clamping rod 301 after adjustment;

[0033] The transmission unit includes a clamping rod 301, a transmission rod 302, a pressing rod 303, and a shifting block 304;

[0034] The clamping rod 301 is axially slidably mounted on the inner wall of the handle 2 and extends to the outside of the handle 2. The clamping rod 301 is used to provide a clamping limit for the hand holding the outer wall of the handle 2.

[0035] The transmission rod 302 is fixed to one end of the clamping rod 301 and is located inside the handle 2. The transmission rod 302 is used to drive the clamping rod 301 to move synchronously.

[0036] The pressing rod 303 is rotatably connected to the end of the transmission rod 302 and extends to the outside of the handle 2. The pressing rod 303 is used to push the transmission rod 302 to move;

[0037] The shift block 304 is fixed to the end of the pressing rod 303, and the shift block 304 is used to drive the pressing rod 303 to rotate synchronously;

[0038] The limiting unit includes a limiting block 305, a limiting groove 306, and a spring 307;

[0039] The limiting block 305 is fixed on the outer wall of the pressing rod 303 and is located inside the handle 2. The limiting block 305 is used to cooperate with the limiting groove 306 to limit the movement of the pressing rod 303.

[0040] The limiting groove 306 is provided inside the handle 2, and the limiting groove 306 is used to provide a limiting space for the limiting block 305 after rotation;

[0041] Two ends of the spring 307 are respectively clamped on the outer wall of the pressing rod 303 and the inner wall of the handle 2 , and the spring 307 is used to give the transmission rod 302 an extrusion thrust in one direction.

[0042] In this embodiment, when the device is needed to scan an object, the thumb gives a thrust to the shift block 304, and the shift block 304 simultaneously drives the pressing rod 303 and the transmission rod 302 to move, so that the two clamping rods 301 connected to the transmission rod 302 are both away from the grip 2. At this time, the finger passes between the clamping rod 301 and the grip 2, and the thumb in contact with the shift block 304 is released, and the shift block 304 is no longer given a squeezing force. At this time, the transmission rod 302 is affected by the elastic force of the spring 307, so that the transmission rod 302 and the transmission rod 302 are affected by the elastic force of the spring 307. The clamping rod 301 approaches the handle 2 until the outer wall of the clamping rod 301 contacts the hand. At this time, the thumb can be used to give the shift block 304 a rotational thrust, so that the shift block 304 drives the pressing rod 303 to rotate synchronously, and the limiting block 305 fixed on the outer wall of the rotating pressing rod 303 will also rotate synchronously, so that the limiting block 305 enters the inner cavity of a limiting groove 306, limiting the movement of the clamping rod 301, completing the limiting of the hand, improving the safety of using the scanner body 1, and making it easy to carry the scanner body 1 around, thereby increasing portability.

[0043] Please refer to Figure 1-Figure 3 There are two clamping rods 301, which are symmetrically distributed on the outer wall of the transmission rod 302. The outer wall of the clamping rod 301 is formed with a groove for fingers to be embedded, and a pad for increasing friction is formed inside the groove. The outer wall of the transmission rod 302 is a "U"-shaped structure as a whole. The inner cavity of the handle 2 is formed with a sliding groove for axial movement of the transmission rod 302. The inner cavity of the limit groove 306 matches the outer wall of the limit block 305, and the inner cavity of the limit groove 306 is formed with a sliding groove for axial movement of the limit block 305.

[0044] In this embodiment: through this structure, after the clamping rod 301 contacts the hand, the limit block 305 will also move to the interface position of the limit slot 306 closest to it, so that the limit block 305 is stuck in the limit slot 306, increasing the limiting force of the clamping rod 301.

[0045] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
