Detailed Description

The present invention will be described in further detail with reference to embodiments shown in the drawings.

Referring to fig. 1 to 3, the pen holder of the embodiment includes a tubular pen cap 1, a forefinger concave surface 11, a middle finger concave surface and a thumb concave surface 12 are provided on an outer peripheral wall of the tubular pen cap 1, a fixing member 2 is provided in the tubular pen cap 1, the fixing member 2 includes a plurality of clamping blocks 21 and a rubber ring 22, a containing cavity 100 is provided in the tubular pen cap 1, the containing cavity 100 is annularly arranged along a circumferential direction of the tubular pen cap 1, a plurality of through grooves 101 communicated with the containing cavity 100 are provided on an inner wall of the tubular pen cap 1, the through grooves 101 are annularly arranged along the circumferential direction of the tubular pen cap 1, the plurality of clamping blocks 21 are one-to-one corresponding to the plurality of through grooves 101, the clamping blocks 21 are slidably connected to the through grooves 101, the rubber ring 22 is embedded into the containing cavity 100, the rubber ring 22 is used for keeping one end of the clamping blocks 21 away from the containing cavity 100 to extend out of the, the end of the clamping block 21 extending out of the through groove 101 is provided with an inclined surface 212, and the inclined surface 212 is used for abutting against the clamping block 21 when a pen extends into the tubular pen cap 1.

In this embodiment, the tubular pen cap 1 is made of silica gel, the concave surface 11 of the index finger, the concave surface of the middle finger and the concave surface 12 of the thumb play a role in limiting the position, when a user uses the pen cap, the correct holding posture is ensured, the tubular pen cap 1 is fixed on a pen holder through the fixing part 2, and the specific installation mode is as follows: when the pen needs to be used, the pen holder can penetrate through the inner wall of the tubular pen holder, the pen holder is firstly abutted against the inclined surface 212 on the clamping block 21, the plurality of clamping blocks 21 move towards the accommodating groove along the through groove 101, the rubber ring 22 is expanded under pressure until the pen holder penetrates through the tubular pen sleeve 1, the clamping block 21 is abutted against the pen holder under the elastic force generated by the deformation of the rubber ring 22, namely, the tubular pen sleeve 1 can be fixed on the pen holder, and the rubber ring 22 has elastic deformation capacity, so that the pen holder with the outer diameter within a certain range can be sleeved in the tubular pen sleeve 1, and the application range is wider.
