[0027] See also Figures 1 to 7 The winding tool of the present invention includes: a spool 1, having a first end and a second end opposite to each other, and the first end is provided with a synchronously rotating winding post 2; a limiting sleeve 3, provided on the spool 1, forming a vertical accommodating space 31 in the limiting sleeve 3, and forming at least one window 32 connected to the accommodating space 31 on the side; a clamping block 4, arranged in the accommodating space 31 of the limiting sleeve 3 through an elastic member 5, with the help of the elastic force of the elastic member 5, the clamping block 4 rises to a static position in the accommodating space 31, so that the top of the clamping block 4 is at least flush with the top of the window 32.

[0028] See also Figure 1 The winding post 2 is installed on the first end of the bobbin 1, and the winding post 2 is coaxial with the bobbin 1. The second end of the winding post 2 is installed on the winding device. The bobbin 1 is controlled by the winding device to rotate circumferentially, so that enameled wire, copper wire and other wires can be wound on the winding post 2.

[0029] See also Figure 1 、 Figure 3 、 Figure 6 、 Figure 7 The limiting sleeve 3 has two windows 32 that are in a straight line and penetrate the limiting sleeve 3 and the accommodating space 31. In the initial state, under the action of the elastic member 5, the clamping block 4 is pushed up to the static position by the elastic member 5. At this time, the upper end surface of the clamping block 4 is at least flush with the top surface of the window 32.

[0030] When the wire needs to be wound on the winding post 2, the block 4 is first pushed downward so that the upper end surface of the block 4 is located in the space limited by the window 32, or the upper end surface of the block 4 is lower than the position of the window 32. Thereafter, one end of the wire is passed through the window 32 of the limiting sleeve 3 to enter the upper end surface of the block 4, and the restriction on the block 4 is released. Under the action of the elastic member 5, the block 4 moves up so that the wire located in the window 32 is clamped by the block 4 and the limiting sleeve 3. Thereafter, the spool 1 is controlled to rotate clockwise or counterclockwise so that the wire is wound on the winding post 2. In this way, the stability of the clamping of the end of the wire can be guaranteed, the effect of the wire winding and forming can be guaranteed, and it is practical. After the wire is wound, the block 4 is pressed downward so that the block 4 and the limiting sleeve 3 no longer clamp one end of the wire, and the wire can be taken out. It has the characteristics of simple structure and convenient operation.

[0031] In one or more embodiments, a through opening 33 communicating with the accommodating space 31 is formed on the top of the limiting sleeve 3 , and a pressing portion 41 extending out of the top of the limiting sleeve 3 through the through opening 33 is formed on the top of the clamping block 4 .

[0032] See also Figure 6 In the initial state, under the action of the elastic member 5, the pressing portion 41 formed on the top of the card block 4 extends out of the through hole 33 opened at the top of the limit sleeve 3, so that the staff can press down on the card block 4, further improving the efficiency of the wire winding of this application and having practicality.

[0033] In one or more embodiments, a through slot 411 communicating with the window 32 is formed through the side of the pressing portion 41 .

[0034] See also Figure 7 When the pressing part 41 is pressed to the predetermined position, the through groove 411 formed on the pressing part 41 is connected to the window 32 formed on the limiting sleeve 3, that is, the channel between the through groove 411 and the window 32 is set in an "I" shape; through this setting, it is possible to further facilitate the placement of one end of the wire body into the window 32 and the through groove 411, thereby improving the clamping efficiency of the wire body.

[0035] In one or more embodiments, the inner wall of the accommodating space 31 of the limiting sleeve 3 extends toward the accommodating space 31 above the window 32 to form a blocking portion 34. With the help of the elastic force of the elastic member 5, the top surface of the block 4 rises to a stationary position to contact the blocking portion 34.

[0036] See also Figure 3 In the initial state, with the help of the elastic force of the elastic member 5, the card block 4 is pushed up to the static position, and the top surface of the card block 4 contacts the blocking portion 34. Through this arrangement, the upward movement position of the card block 4 can be further restricted, avoiding the problem of the card block 4 moving in the accommodating space 31 of the limit sleeve 3 due to the large centrifugal force when the spool 1 drives the card block 4 to rotate, causing the problem of loose connection of the wire body, thereby ensuring the quality and stability of the wire body wound on the winding rod 2.

[0037] In one or more embodiments, a stepped layer 11 is formed on the bobbin 1, and the limiting sleeve 3 is disposed on the stepped layer 11. Figure 1 The limiting sleeve 3 is installed on the stepped layer 11 of the bobbin 1 by means of bolts. This arrangement can reduce the difficulty of installing the limiting sleeve 3 and other components.

[0038] In one or more embodiments, a fixed shaft 6 is installed at the first end of the spool 1, and the winding post 2 is sleeved on the fixed shaft 6, and a locking structure is configured on the end of the fixed shaft 6 away from the spool 1 to lock the winding post 2 on the fixed shaft 6; the locking structure includes at least at least one L-shaped slot 71 opened on the circumferential surface of the fixed shaft 6 away from the spool 1, a limiting ring 72 that can be sleeved on the fixed shaft 6, and a limiting block 73 configured in the limiting ring 72 and adapted to be engaged with the L-shaped slot 71; the limiting ring 72 is formed with an avoidance space 721 on the side facing the spool 1, and an elastomer 74 is configured in the avoidance space 721. With the help of the elastic force of the elastomer 74, the limiting ring 72 is pushed to a stationary position in the direction away from the spool 1, so that the limiting block 73 is clamped in the L-shaped slot 71.

[0039] See also Figures 3 to 5 , the fixed shaft 6 is coaxial with the spool 1; the winding post 2 is detachably mounted on the fixed shaft 6. When the winding post 2 is mounted on the fixed shaft 6, the winding post 2 is restricted on the fixed shaft 6 by the locking assembly and rotates synchronously with the spool 1 and the fixed shaft 6.

[0040] See also Figure 4 The locking structure includes an L-shaped slot 71, a limiting ring 72, a limiting block 73 and an elastic body 74, which are opened on the circumferential side surface of the end of the fixed shaft 6; wherein, the L-shaped slot 71 includes a horizontal portion 711 and a vertical portion 712, one end of the horizontal portion 711 is opened on the end of the fixed shaft 6 away from the spool 1, and the vertical portion 712 is opened on the circumferential surface of the fixed shaft 6 around the central axis of the fixed shaft 6, and the horizontal portion 711 is connected to the vertical portion 712 to form an L-shaped slot body.

[0041] When the winding post 2 needs to be assembled on the fixed shaft 6, the winding post 2 is first sleeved on the fixed shaft 6, and then the elastic body 74 is arranged in the avoidance space 721 of the limiting ring 72, and then the "I"-shaped limiting block 73 in the limiting ring 72 is aligned with the horizontal part 711 of the L-shaped slot 71, and the limiting ring 72 is pushed onto the fixed shaft 6 so that the limiting block 73 enters the horizontal part 711 of the L-shaped slot 71. At this time, the elastic body 74 is in a compressed state, and then it moves toward the vertical part 711 of the L-shaped slot 71. The limiting ring 72 is rotated in the direction of 712 so that the limiting block 73 fixed in the limiting ring 72 enters the vertical part 712 of the L-shaped slot 71, and the control of the limiting ring 72 is released. The elastic body 74 gradually returns to its initial state. Under the action of the elastic body 74, the limiting ring 72 and the limiting block 73 are pushed in the direction away from the spool 1 so that the limiting block 73 is tightly pressed against the vertical part 712 of the L-shaped slot 71, forming an assembly for the winding column 2. It has the characteristics of simple structure, convenient operation, and practicality.

[0042] When the wire is wound on the winding post 2, the limiting ring 72 can be screwed in the reverse direction to allow the limiting block 73 to exit the vertical portion 712 of the L-shaped slot 71, and then the limiting ring 72 can be pulled out to remove the winding post 2.

[0043] In one or more embodiments, the elastic body 74 may be an elastic rubber pad or a spring.

[0044] In one or more embodiments, the elastic member 5 is a spring or elastic steel.
