Referring to fig. 1 to 4, a device for easily detaching a dart needle comprises a clamp body 2, a screw rod 1, a connecting tool 3 and a clamping device; the screw rod 1 is screwed into the clamp main body 2 and is fixedly connected with the connecting tool 3, so that a first screw hole matched with the screw rod 1 is formed in the clamp main body 2; the clamping device is connected with the clamp main body 2 and is arranged opposite to the screw rod 1. In the embodiment, the dart 5 comprises a dart body 503, and a needle 501 and a dart tail 502 connected to two ends of the dart, the dart 5 is disposed in the fixture body 2, the dart tail 502 is fixed on the connecting tool 3, and the needle 501 is clamped and fixed on the fixture body 2 by a clamping device. In the embodiment, a handle 4 is arranged at one end of the screw rod 1, which is far away from the clamp main body 2, and an opening groove 9 is arranged on the handle 4; the opening groove 9 is an inner hexagonal groove matched with a hexagonal wrench for use.

In other embodiments, the opening groove 9 is a triangular or dodecagonal groove.

When the dart board is used, the screw rod 1 is screwed out of the clamp body 2, the screw rod 1 exerts pulling force on the connecting tool 3 when being screwed out, and the dart board 502 is fixed by the connecting tool 3, and the needle head 501 is also clamped and fixed on the clamp body 2 by the clamping device, so that the connecting tool 3 can generate pulling force on the dart board 502, and the needle head 501 is separated from the dart board 503 under the combined action of the clamping device and the dart board 502. Handle 4 on the screw rod 1 can the person of facilitating the use exert the effect to screw rod 1, be equipped with on the handle 4 and open recess 9, using under the condition that handle 4 still can't back out screw rod 1, the user can use the spanner to act on and open recess 9, and is more laborsaving like this.

Referring to fig. 1, in an embodiment, the connection tool 3 includes a connection screw 301, a connection body 302 and a connection pin 303; the connecting screw 301 is fixed on the connecting body 302, and the dart tail 502 is provided with a second screw hole matched with the connecting screw 301; a connecting pin 303 is arranged on one side of the connecting body 302 far away from the connecting screw 301, and the connecting pin 303 is wedged into the connecting body 302 and the connecting column 101 at the tail end of the screw rod 1 simultaneously. In an embodiment, the connection pin 303 is a detachable pin such as a cotter pin or a threaded cylindrical pin. In the embodiment, the connection screw 301 has a reverse direction of the external thread of the screw rod 1.

In other embodiments, the connection screw 301 may be replaced by a pin connection that facilitates disassembly.

In some embodiments, the connection column 101 is fixedly connected to the end of the screwing end of the screw rod 1, the diameter of the connection column 101 is smaller than the diameter of the thread section of the screw rod 1, the connection column 101 is provided with a pin hole matched with the connection pin 303, and the connection column 101 is wedged into the connection body 302.

In other embodiments, the connecting column 101 is the end of the threaded section of the screw 1, and the pin hole matched with the connecting pin 303 is directly established in the threaded section, and the screw 1 is wedged into the connecting body 302 together with the pin hole.

When the screw bolt is used, the connecting screw 301 on the connecting tool 3 can be firstly screwed into the dart 502, then the screw bolt 1 is screwed into the clamp main body 2, and the connecting column 101 at the tail end of the screw bolt 1 is connected to the connecting body 302 by the connecting pin 303, when the screw bolt 1 is screwed out of the clamp main body 2, the connecting tool 3 can rotate together, but the screwing directions of the connecting screw 301 and the external thread of the screw bolt 1 are opposite. Therefore, the screw will not be screwed out from the second screw hole on the dart board 502, but rather tends to be screwed in, so as to ensure that the connection tool 3 can be stably connected to the dart board 502 when the screw rod 1 is screwed out.

Referring to fig. 1 and 2, in an embodiment, the clamp body 2 is provided with a through hole connected to a channel 201 for placing a clamping device; one end of the through hole, which is far away from the channel 201, is provided with a guide groove 202. In an embodiment, the through hole is larger in diameter than the needle 501, and the needle 501 is wedged into the through hole and enters the channel 201 connected to the through hole, and finally is clamped by a clamping device. When the needle is used, the guide groove 202 can facilitate the needle 501 to penetrate into the through hole, and the actual radial size of the needle 501 is increased by considering that the needle 501 may be seriously bent after being scrapped, so that the needle 501 and the through hole can be in clearance fit; the channel 201 is directly connected to the through hole so that a needle 501 entering the body 2 of the jig from the through hole can be gripped by the gripping means in the channel 201.

Referring to fig. 3, in an embodiment, the clamping device includes a plug 7 and a clamping screw 8, the clamping screw 8 is screwed into the clamp body 2, and a screwed end of the clamping screw enters the channel 201 along a direction parallel to the outer diameter of the through hole; the plug 7 enters the channel 201 along the direction parallel to the through hole; therefore, the screwing end of the clamping screw 8 is positioned in the channel 201 and is abutted against the needle 501 along the outer diameter direction of the needle 501; the plug 7 enters the channel 201 along the direction parallel to the needle 501 and abuts against the needle 501. In an embodiment, the plug 7 is detachably connected to the clamp body 2. In an embodiment, the plug is further provided with a central groove 6, the central groove 6 is located at a position where the plug 7 abuts against the needle 501, and the central groove 6 is a groove left when the plug is processed, and can also play a role in supporting the needle 501 at this time. In some embodiments, the plug 7 may be made of a material such as wood, which has a certain toughness but soft surface, and this has the advantage that the needle 501 can be wedged into the plug 7 and engaged with each other, so that the needle 501 can be fixed more firmly. When the dart pressing clamp is used, the plug 7, the inner wall of the through hole and the clamping screw 8 jointly act on the needle 501, so that the needle 501 is clamped inside the clamp body 2 by the clamping device, the screw rod 1 provides pulling force when being screwed out, the needle 501 is separated from the dart body 503, and the needle 501 falls off in the channel 201 after being separated from the dart body 503 or is wedged into the plug 7 and taken out of the channel 201 together with the plug 7.

In some embodiments, the clamp body 2 is provided with a clamping screw 8, and the needle 501 is clamped by the clamping screw 8.

Referring to fig. 4, in other embodiments, two clamping screws 8 are arranged on the clamp body 2, the two clamping screws 8 are oppositely and parallelly arranged around the needle 501, and the screwing-in and screwing-out of the two clamping screws 8 can be adjusted to clamp and loosen the needle 501.

The above-mentioned embodiments are only one of the preferred embodiments of the present invention, and the ordinary changes and substitutions performed by those skilled in the art within the technical scope of the present invention should be included in the protection scope of the present invention.
