Embodiment 1
[0041] figure 1 It is a structural schematic diagram of the writing instrument 100 indicating the holding pressure.
[0042] exist figure 1 Among them, the writing instrument 100 indicating the holding pressure includes a pen barrel 110 and a pressure medium 120 and an indicating unit 130 disposed on the pen barrel 110 . The pen tube 110 is provided with an upper cavity 111 and a lower cavity 112, and the upper cavity 111 and the lower cavity 112 together form a closed space. Wherein, the pressure medium 120 is disposed in the lower cavity 112 , and the indicating unit 130 is disposed on the upper cavity 111 . The outer wall of the upper cavity 111 is provided with a scale line 131 indicating the holding pressure. The scale line 131 can be arranged on the inner surface of the outer wall of the upper cavity 111 or on the outer surface of the outer wall of the upper cavity 111 . The outer wall of the lower cavity 112 is made of elastic material, and the outer wall of the lowe...
Embodiment 2
[0049] figure 2 Another schematic structural view of the writing instrument 100 for indicating gripping pressure provided by the embodiment of the present invention.
[0050] The difference from Example 1 is that in figure 2 Among them, the pressure medium 120 is configured as a piston 122 and at least one piston rod 123 connected with the piston 122 . The piston 122 is arranged between the upper cavity 111 and the lower cavity 112 in a non-working state, and forms a closed space with the lower cavity 112; one end of at least one piston rod 123 is connected with the piston 122, and the other end is along the upper cavity 111. stick out. The top of the upper cavity 111 is provided with at least one outlet 114 suitable for at least one piston rod 123 to stretch out; the piston 122 drives at least one piston rod 123 to move along the at least one outlet 114 under the holding pressure; the displacement change of the piston 122 indicates the grip holding pressure and / or holdin...
Embodiment 3
[0053] image 3 A schematic structural view of a writing instrument 100 provided with a refill 101 for indicating grip pressure; Figure 4 A schematic diagram of the structure of the writing tool 100 indicating gripping pressure installed on the writing pen 102 provided by the embodiment of the present invention.
[0054] exist image 3 Among them, as an example and not a limitation, the barrel 110 of the writing instrument 100 indicating the holding pressure has a structure that can directly install the refill 101, and the refill 101 can be directly installed in the barrel 110 to write.
[0055] exist Figure 4 The writing instrument 100 indicating the holding pressure is detachably mounted on the writing pen 102 for writing. The writing instrument 100 indicating the holding pressure can be connected with the internal thread provided on the outside of the bottom of the writing pen 102 through the external thread provided on the inner wall of the bottom of the pen tube 110 ...
