as shown in fig. 1 to fig. 3, an embodiment of the present application provides a wand 100, including: the pen comprises a shell 1, a pen point 2 and a reinforcing piece 3. The shell end 11 of the shell 1 is provided with a scanning port 12 communicated with the interior of the shell 1; the pen end 21 of the pen head 2 is telescopically arranged in the scanning port 12; the reinforcement 3 is housed inside the case 1, and the abutting end 31 of the reinforcement 3 abuts against the inner wall of the case end 11.

The principle of preventing the scanner pen 100 from being stuck due to falling is as follows:

the dropping of the wand 100 at a specific angle refers to an angle formed by the length direction of the wand 100 and the ground when the wand 100 is in contact with the ground, the specific angle refers to a downward pointing direction of the nib 2 of the wand 100, and the length direction of the wand 100 and the ground form an angle of 70 degrees to 75 degrees, which is further explained in the following, the wand 100 of the present embodiment also has an effect of preventing jamming at other dropping angles. The nib 2 and the shell end 11 of the scanning pen 100 collide with the ground, the nib 2 and the shell end 11 deform, and because the inner shell wall of the shell end 11 is abutted by the reinforcing part 3, the reinforcing part 3 supports the shell end 11 and further reduces the deformation of the shell end 11, thereby avoiding the situation that the shell end 11 deforms to have too large amplitude and abuts against the nib 2, and causing the nib 2 to be blocked in extension and retraction.

Specifically, this application is based on theoretical calculation, and when obtaining that the interval after two closed angles of shell end 11 of casing 1 warp is less than or equal to 15.07mm, can take place nib 2 card and die, through falling the emulation calculation and obtaining, the structure of wand 100 that does not adopt this embodiment scheme now is that distance after two closed angles of shell end 11 of casing 1 warp for 14.977mm when 75 falls, and distance after two closed angles of shell end 11 of casing 1 warp for 15.021mm when 70 falls, all is less than 15.07mm, can take place nib 2 card and die. The calculation result of the structure of the scanning pen 100 according to the embodiment of the present application shows that when the scanning pen falls at 75 °, the distance between two sharp corners of the shell end 11 of the housing 1 after deformation is 15.082mm, and the distance between two sharp corners of the shell end 11 of the housing 1 after deformation is 15.145mm when the scanning pen falls at 70 °, both of which are greater than 15.07mm, so that the risk of locking is significantly reduced. Carry out the drop test contrast of two kinds of structures simultaneously, former structure 4/10 falls 2 card of nib and dies, and the structure 0/10 falls 2 card of nib and dies of this application, and the test result of two kinds of structures is unanimous with the emulation result, shows that the dead obvious reduction of structure nib 2 card in this application.

By adopting the technical scheme, the abutting end 31 of the reinforcing part 3 abuts against the inner shell wall of the shell end 11, so that the deformation amplitude of the shell end 11 when falling is reduced, and further the situation that the shell end 11 abuts against the pen point 2 due to overlarge deformation amplitude to cause the resistance of the extension and retraction of the pen point 2 is avoided; in addition, abutting end 31 is connected to case end 11 in an abutting manner, that is, abutting end 31 and case end 11 can still slide relative to each other after being deformed by an external force, so as to avoid that abutting end 31 is fixedly connected to case end 11, and the two can not slide relative to each other to cause stress concentration, thereby causing case end 11 to break under the action of stress.
