Referring to fig. 1-3, the embodiment of the utility model provides a bracelet capable of effectively preventing a screw 40 from being lost, the bracelet is provided with a first part 10 and a second part 20, the first part 10 is provided with a first end 11, the second part 20 is provided with a second end 21, and the first part 10 and the second part 20 are hinged, so that the first end 11 and the second end 21 can be separated relatively to form an opening 30 for the bracelet, thereby realizing wearing.

The first end portion 11 is provided with a screw hole 111 and a first receiving hole 112 connected to the screw hole 111, the screw 40 is provided in the screw hole 111, and the second end portion 21 is provided with a second receiving hole 211. The threaded hole 111 is connected with a screw rod 41 of the screw 40, a raised head 42 is arranged at the end part of the screw rod 41, and the diameter of the raised head 42 is larger than that of the threaded hole 111. The cap 43 of the screw 40 may be exposed to the outside of the first end 11 for the user to screw.

When the first portion 10 and the second portion 20 are rotated to make the first end portion 11 and the second end portion 21 approach and close the opening 30, the first receiving hole 112 may face the second receiving hole 211, and the screw 41 is rotated relative to the threaded hole 111 to receive the tab 42 in the first receiving hole 112 or insert the tab into the second receiving hole 211.

In use, the screw 40 is rotated to insert the boss 42 into the second receiving hole 211, so that the first end portion 11 and the second end portion 21 are prevented from being separated in the separation direction, and the first end portion 11 and the second end portion 21 are coupled. When the bracelet is disassembled, the screw 40 is rotated reversely, so that the raised head 42 can slide out of the second receiving hole 211 and then be received in the first receiving hole 112, at the moment, the raised head 42 does not protrude out of the first end portion 11, and therefore separation of the first end portion 11 and the second end portion 21 in the separation direction is not affected, and in addition, due to the existence of the raised head 42, the screw 40 cannot be separated from the first end portion 11, and the loss of the screw 40 is prevented.

It should be noted that if the tab 42 protrudes from the first end portion 11, during the separation process, the first end portion 11 and the second end portion 21 are separated in advance along the axial direction of the screw 40 to make the tab 42 leave the second receiving hole 211, and then the first end portion 11 and the second end portion 21 can be directed toward the separation direction, which may cause the bracelet to be deformed or may cause the hinge to be loosened, and this problem can be avoided by the present invention.

Further, a first notch 101 is formed on a first surface of the first end portion 11, which is perpendicular to the separation direction, and a second notch 201 is formed on a second surface of the second end portion 21, which is perpendicular to the separation direction, wherein the first surface and the second surface are opposite, and in fig. 1 and fig. 2, the first surface and the second surface are a right side surface and a left side surface, respectively. When the first end portion 11 and the second end portion 21 are close to each other, the first end portion 11 is disposed in the second notch 201 and the second end portion 21 is disposed in the first notch 101.

Further, a hook 51 is connected to the front end of the first end portion 11, and a slot 52 is formed at the back end of the bracelet body of the bracelet, which is close to the second end portion 21; or the front end of the second end part 21 is connected with a clamping hook 51, and the rear end of the bracelet body of the bracelet, which is close to the first end part 11, is provided with a clamping groove 52. The hook 51 can be connected with the slot 52. Only one surface of the engaging groove 52 is open for the engaging hook 51 to slide in or disengage, and the disengaging direction of the engaging hook 51 and the engaging groove 52 is perpendicular to the disengaging direction and the recess direction of the first notch 101. When the hook 51 is connected to the engaging groove 52, the surfaces of the first end portion 11 are engaged with the surfaces of the second end portion 21.

In this embodiment, the first end portion 11 and the second end portion 21 are coupled in advance by the hook 51 and the slot 52, and then the screw 40 is rotated to insert the tab 42 into the second receiving hole 211, so that the tab 42 is further coupled with the second receiving hole 211, and the first end portion 11 and the second end portion 21 are difficult to separate.
