[0020] Example 1
[0021] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a sewing device for preventing a thread bobbin from falling off, comprising: a chassis 1, a thread bobbin body 3 is arranged on the top of the chassis 1, a groove 4 is provided on the chassis 1, a clamping mechanism 5 is arranged inside the chassis 1, the clamping mechanism 5 comprises a bidirectional threaded rod 51, the bidirectional threaded rod 51 runs through the inside of the chassis 1, one end of the bidirectional threaded rod 51 is fixedly connected to a limiting block 52, a limiting groove matching the limiting block 52 is provided inside the chassis 1, a threaded sleeve block 53 is passed through the outer surface of the bidirectional threaded rod 51, the number of the threaded sleeve blocks 53 is two, the threaded sleeve blocks 53 are threadedly connected to the bidirectional threaded rod 51, a sliding groove matching the threaded sleeve block 53 is provided on the chassis 1, a clamping block 54 is fixedly connected to the top of the threaded sleeve block 53, and a rubber block 55 is fixedly connected to the outer surface of the clamping block 54.
[0022] In this embodiment, by providing a clamping mechanism 5, the sewing equipment of this type can clamp the thread barrel body 3 more stably when in use, and the thread barrel body 3 will not fall off due to accidental touch. Since the two-way threaded rod 51 can threadably drive the two threaded sleeves 53, the two threaded sleeves 53 can slide in the same direction or opposite directions at the same time, so as to clamp or release the thread barrel body 3. In addition, when the threaded sleeve 53 is threadably driven by the two-way threaded rod 51, it will also be restricted by the sliding groove provided on the chassis 1, so that the threaded sleeve 53 can slide on the two-way threaded rod 51, and the clamping block 54 is fixedly connected to the threaded sleeve 53. The rubber block 55 can be used to increase the friction with the thread barrel body 3, so as to firmly clamp the thread barrel body 3.
[0023] Example 2
[0024] like Figure 1-Figure 3 As shown, a fixing ring 56 passes through the outer surface of the bidirectional threaded rod 51, and the fixing ring 56 is fixedly connected to the bidirectional threaded rod 51. An arc block 57 is fixedly connected to one side of the fixing ring 56, and a rotating block 58 is fixedly connected to the end of the arc block 57 away from the fixing ring 56. There are two rotating blocks 58 and two arc blocks 57. A rotating groove matching the rotating block 58 and the arc block 57 is opened inside the chassis 1. A turntable 59 is fixedly connected to the end of the bidirectional threaded rod 51 away from the limit block 52, and the outer surface of the turntable 59 is fixedly connected to the anti-slip pad 501.
[0025] In this embodiment, a fixing ring 56, an arc block 57 and a rotating block 58 are provided, and the arc block 57 and the rotating block 58 can rotate in a rotating groove provided in the chassis 1, and are used in conjunction with the limit block 52. When the bidirectional threaded rod 51 rotates, the limit block 52 will rotate in the limit groove provided in the chassis 1, thereby ensuring the stability of the rotation of the bidirectional threaded rod 51, and an anti-skid pad 501 is fixedly connected to the turntable 59, and the anti-skid pad 501 is used to play an anti-skid role, so that the turntable 59 is more easily rotated and the friction damage to the hands of the weaver caused by the turntable 59 can be avoided.
[0026] Working principle:
[0027] like Figure 1-Figure 3 As shown, when the utility model is in use, the spool body 3 can be placed in the groove 4 provided on the chassis 1 first, and the anti-skid pad 501 is used to drive the turntable 59 to rotate. When the turntable 59 rotates, the bidirectional threaded rod 51 can be driven to rotate. At this time, the bidirectional threaded rod 51 will drive the limit block 52 to rotate in the limit groove provided in the chassis 1, and the fixing ring 56 will be used to drive the arc block 57 and the rotating block 58 to rotate in the rotating groove provided in the chassis 1, so as to stably rotate the bidirectional threaded rod 51. At the same time, the bidirectional threaded rod 51 will also threadably drive the two threaded sleeves 53 when rotating, and the threaded sleeves 53 can slide on the bidirectional threaded rod 51 under the restriction of the sliding groove provided on the chassis 1, and then the spool body 3 can be gradually clamped and fixed by the clamping block 54, and when the clamping block 54 clamps the spool body 3, the clamping block 54 will slightly compress and deform the rubber block 55, and the rubber block 55 is closely fitted with the spool body 3, so that the spool body 3 can be more stable when in use.
