The control circuit board and the battery as well as the signal transmitter and the signal receiver are common signals on the market, and their coordination and use with each other are all existing technologies.

[0028] The side wall of the housing 100 is provided with a slide groove 110, and the side wall of the slide groove 110 is matched with a plurality of positioning grooves 111. The side wall of the housing 100 is clamped with a protective sheet 120, and a pit matched with the button 101 is provided on the rear side of the protective sheet 120. The side wall of the protective sheet 120 is fixed with a fixing sheet 121 and a clamping sheet 123, and the fixing sheet 121 and the clamping sheet 123 are hard plastic sheets. The side wall of the fixing sheet 121 is fixed with a fixing block 122, and the side wall of the clamping sheet 123 is provided with a clamping strip 124, and the clamping sheet 123 is clamped with the clamping hole 125 through the clamping strip 124;

[0029] The clamping piece 200 is matched with the rear side of the shell 100, and a cavity 230 is provided on the side wall of the clamping piece 200. A fixing strip 201 is provided inside the cavity 230. Elastic bands 202 are provided on both sides of the fixing strip 201. Nylon bands 220 are fixed to the side walls of the elastic band 202. The nylon bands 220 are woven from wear-resistant nylon threads commonly found on the market. Side pieces 221 are fixed to both ends of the clamping piece 200. A spacer 210 is provided on the side wall of the clamping piece 200. A sponge sheet 211 is provided on the side wall of the spacer 210. The sponge sheet 211 is a soft sponge commonly found on the market. An anti-slip sheet 212 is provided on the side wall of the sponge sheet 211. The anti-slip sheet 212 is a thinner rubber sheet, and its side wall is provided with anti-slip patterns.

[0030] Specifically, a groove 130 matched with the protection sheet 120 is provided on the side wall of the housing 100 .

[0031] Furthermore, a clamping hole 125 is provided on the side wall of the slide slot 110 .

[0032] Furthermore, the nylon belt 220 penetrates through the side wall of the side piece 221 .

[0033] Furthermore, the elastic band 202 is fitted into the interior of the cavity 230 , and the elastic band 202 is a common elastic fabric band on the market.

[0034] It is worth noting that the anti-slip sheet 212 has a wave-shaped structure.

[0035] It is worth noting that fixing bolts are disposed on the side wall of the nylon belt 220 , and the nylon belt 220 is fixed to the rear side of the housing 100 .

[0036] In addition, the circuits, electronic components and modules involved in the utility model are all prior art, and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to the internal structure and method.

[0037] Working principle: when the control pen is not in use and the button 101 needs to be protected, first pull the protective sheet 120 outward and at the same time depress the snap-in sheet 123 so that the snap-in strip 124 of the snap-in sheet 123 is disengaged from the snap-in hole 125. At this time, the fixing block 122 slides from the inside of the positioning groove 111 to the inside of the slide groove 110. Then slide the protective sheet 120 upward until the fixing sheet 121 at the upper end of the protective sheet 120 is aligned with the uppermost positioning groove 111. Then press the protective sheet 120. At this time, the fixing block 122 enters the inside of the positioning groove 111. At the same time, the snap-in sheet 123 is snap-fitted with the upper snap-in hole 125. At this time, the protective sheet 120 cooperates with the outside of the button 101, thereby protecting the button 101 of the computer teaching control pen and preventing the button 101 from being exposed to the outside and being damaged by collision with objects, thereby protecting the computer teaching control pen. When holding the control pen, insert the finger between the sponge sheet 211 and the shell 100. At this time, the elastic band 202 uses its own elasticity to pull the nylon belt 220 into the cavity 230, so that the clamping piece 200 is close to the outside of the finger. At this time, the anti-slip sheet 212 fits the outside of the finger to improve the stability when holding. Therefore, when holding the control pen for computer teaching, the clamping piece 200 can be used to press on the finger to increase the stability when holding, and avoid the situation that the hand slips and falls when holding the control pen.
