DETAILED DESCRIPTION

[0027] The wrist-hooking-preventing correcting piece will be described in detail below in combination with specific embodiments.

[0028] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , a wrist-hooking-preventing correcting piece comprises a pen sleeve part 1 for placing a pen barrel, a holding part 2 corresponding to the position of a palm and a correcting piece 16 supporting a wrist, the holding part 2 comprises a telescopic structure, one end of the telescopic structure is connected with the correcting piece 16, the other end is connected with the pen sleeve part 1, and the telescopic structure further comprises a limiting structure matched with the telescopic structure.

[0029] In use, as shown in Figure 7 , a user installs the pen barrel in the pen sleeve part 1, holds the palm on the holding part 2 and makes the correcting piece 16 adhere to the wrist part. The holding part 2, the correcting piece 16 and the pen sleeve part 1 are all of hard structure, which supports the palm and the wrist of the user and keeps them in the correct angle, avoiding the generation of wrist hooking, thus helping to correct the pen holding posture, protect the wrist and improve the writing quality.

[0030] As shown in Figure 3 , Figure 4 , Figure 5 , Figure 6 , the telescopic structure comprises a shell one 3 and a shell two 4 which can be sleeved; one end of the shell one 3 is connected with the correcting piece 16, the other end is sleeved in the shell two 4, one end of the shell two 4 is connected with the pen sleeve part 1; the side of the shell two 4 facing outward from the palm is provided with a mounting hole 5, the limiting structure comprises a button 6 passing through the mounting hole 5, catches 7 on both sides of the bottom of the button 6 and an elastic piece 8 at the bottom of the button 6; the shell one 3 is provided with a sliding slot 9 for the button 6 to pass through on the side facing outward from the palm, and the length direction of the inner side of the sliding slot 9 is uniformly provided with catch grooves 10 matched with the catches 7.

[0031] Under the elastic force of the elastic piece 8, the button 6 is popped outward, the catches 7 are clamped in a certain catch groove 10, when different users need to adjust the length of the correcting piece according to the length of their palms, the button 6 is pressed to make the catches 7 disengage from the corresponding catch groove 10, at this time the button 6 can slide in the sliding slot 9, thus the shell one 3 can move relatively along the shell two 4, and the length of the correcting piece is adjusted.

[0032] The bottom of the button 6 is provided with a guide plate 11, and the side of the shell 2 4 facing the palm is provided with a guide buckle 12 corresponding to the button 6. Specifically, the side of the shell 2 4 facing the palm is provided with a side hole 20, and the guide buckle 12 includes a base, a mounting column in the middle of the base for mounting the elastic element 8, and a connecting plate on both sides of the upper part of the base. The end of the connecting plate is provided with a buckle, and the guide buckle 12 is buckled in the side hole 20 through the buckle. The elastic element 8 is a spring, which is mounted on the mounting column. The guide plate 11 on the bottom of the button 6 can slide in the inside of the connecting plate on both sides of the upper part of the base.

[0033] In other embodiments (not shown): the telescopic structure can be a shell 1 3 and a shell 2 4 that are connected to each other. The shell 1 3 is sleeved inside the shell 2 4. The outer side of the shell 2 4 can be provided with a threaded hole. The limiting structure can be a bolt structure of the threaded hole. The shell 1 3 is fixed inside the shell 2 4 by screwing.

[0034] In other embodiments (not shown): the telescopic structure includes a shell 1 3 and a shell 2 4 that can slide relative to each other. One end of the shell 1 3 is connected to the correcting element 16, and the other end is slidably arranged on the shell 2 4. For example, a dovetail groove is provided on the shell 2 4, and the shell 1 3 can be slidably arranged in the dovetail groove. One end of the shell 2 4 is connected to the pen sleeve 1. The side of the shell 2 4 facing the palm is provided with a mounting hole 5. The limiting structure includes a button 6 passing through the mounting hole 5, a catch 7 on both sides of the bottom of the button 6, and an elastic element 8 at the bottom of the button 6. The shell 1 3 is provided with a sliding groove 9 on the side facing the palm, which can be passed through by the button 6. The length direction of the inside of the sliding groove 9 is uniformly provided with a catch groove 10 matched with the catch 7. Under the action of the elastic force of the elastic element 8, the button 6 is popped outwards, and the catch 7 is caught in a certain catch groove 10 position. When different users need to adjust the length of the corrector according to the length of their palms, the catch 7 is pressed to disengage from the corresponding catch groove 10. At this time, the button 6 can slide inside the sliding groove 9, so that the shell 1 3 can move relative to the shell 2 4, thereby adjusting the length of the corrector and realizing the length of multiple gears.

[0035] As shown in Figure 3 , Figure 4 , a soft sleeve 13 is sleeved on the outside of the holding part. The soft sleeve 13 is used to improve the user's hand feeling and facilitate long-time holding. At the same time, the two sides of the soft sleeve 13 are provided with soft supporting elements 14 that can open the palm. The soft supporting elements 14 are semicircular or semi-elliptical or rectangular with rounded corners, etc. The soft supporting elements 14 can open the palm part of the user during holding the corrector, thereby helping the user form good habits of holding the pen.

[0036] As shown in Figure 3 , Figure 4 , Figure 5 , Figure 7As shown, the pen sleeve part 1 is connected with the rear side of the end of the holding part 2, and forms an avoiding table 15 between the front side of the pen sleeve part 1 and the end of the holding part 2. When the present corrector is used with the pencil holder 19, the pencil holder 19 is sleeved on the pen barrel, and during the writing process when the user's fingers pinch the pencil holder, the avoiding table 15 at this position is used to place the pencil holder 19 a distance backward when used with the pencil holder 19, so as to facilitate the child user to completely hold the pencil holder 19.

[0037] The corrector 16 extends from the lower end of the holding part 2 to the wrist part, and is adapted to the shape of the wrist part, so as to better fit the wrist. The rear end of the corrector 16 is a T-shaped structure, the narrow head of the T-shaped structure is fixedly connected with the shell 3, and the wide head is arc-shaped, so as to better fit the wrist.

[0038] A through hole 17 is arranged in the middle of the pen sleeve part 1, and a soft pen sleeve 18 is arranged in the through hole 17. The soft pen sleeve 18 is provided with a sleeve hole, and an elastic clamping tooth is arranged in the inner ring of the sleeve hole, so that the pen barrel can be inserted into the soft pen sleeve 18 and clamped tightly.
