Description

Technical Field

[0001] The utility model relates to a combination stick. Background Art

[0002] A stick is a commonly used tool with a wide range of uses, but its fixed length results in a small range of use. It is usually necessary to prepare sticks of different lengths for emergency use. Although the existing combination sticks can extend the length of the stick, the joints are usually plug-in, which makes it easy to break during installation. Therefore, a combination stick that is not easy to break is needed.

[0003] In view of the above reasons, how to reduce the possibility of the combined sticks breaking at the joints is exactly the problem considered in this application. Utility Model Content

[0004] In view of the shortcomings of the prior art, a combined stick is provided, which can reduce the possibility of the combination breaking at the joint.

[0005] To achieve the above-mentioned purpose, the following technical scheme is provided: a combination stick, comprising a first stick body, a second stick body and a connecting assembly, wherein the first stick body is fixedly connected to a first threaded sleeve at one end close to the second stick body, the second stick body is fixedly connected to a second threaded sleeve at one end close to the first stick body, the first threaded sleeve is rotatably connected to a first threaded tube, the first threaded tube is connected to a positioning ring, the positioning ring is provided with a plurality of tooth grooves, the second threaded sleeve is rotatably connected to a second threaded tube, the second threaded tube is connected to positioning teeth for inserting into the tooth grooves, the connecting assembly is provided with a first latch hole at one end close to the first stick body, the first threaded sleeve is provided with a second latch hole, the first threaded tube is provided with a third latch hole, the connecting assembly is provided with a fourth latch hole at one end close to the second stick body, the second threaded sleeve is provided with a fifth latch hole, and the second threaded tube is provided with a sixth latch hole;

[0006] After the positioning tooth is inserted into the tooth groove, the first latch hole, the second latch hole and the third latch hole are connected, and the fourth latch hole, the fifth latch hole and the sixth latch hole are connected.

[0007] In summary, the above technical solution has the following beneficial effects: the tooth groove and the positioning teeth can form a gear lock. When the first stick body and the second stick body need to be spliced, the connecting assembly is first inserted into the first stick body and the second stick body, and then the first threaded sleeve is lowered close to the second threaded sleeve, and the first threaded tube and the second threaded tube are rotated to insert the positioning teeth into the tooth groove. At this time, the two latches can be respectively inserted into the connecting hole formed by the first latch hole, the second latch hole and the third latch hole and the connecting hole formed by the fourth latch hole, the fifth latch hole and the sixth latch hole;

[0008] Since the gear may break during the striking process, the structure is increased to improve its strength. The utility model uses the positioning teeth and the tooth groove insertion method to leave a gap when the first stick body and the second stick body are combined, providing a buffer for the relative movement of the first stick body and the second stick body to prevent breakage. On the other hand, it can prevent the first stick body and the second stick from rotating relative to each other, and then cooperate with the connecting component to effectively improve the stability of the connection.

[0019] Reference Figure 1-3As shown, a combination stick includes a first stick body 1, a second stick body 2 and a connecting assembly 3, wherein the first stick body 1 is fixedly connected to a first threaded sleeve 4 at one end close to the second stick body 2, the second stick body 2 is fixedly connected to a second threaded sleeve 5 at one end close to the first stick body 1, the first threaded sleeve 4 is rotatably connected to a first threaded tube 41, the first threaded tube 41 is connected to a positioning ring 42, the positioning ring 42 is provided with a plurality of tooth grooves 43, the second threaded sleeve 5 is rotatably connected to a second threaded tube 51, the second threaded tube 51 is connected to a positioning tooth 52 for inserting into the tooth grooves 43, the connecting assembly 3 is provided with a first latch hole 31 at one end close to the first stick body 1, the first threaded sleeve 4 is provided with a second latch hole 44, the first threaded tube 41 is provided with a third latch hole 45, the connecting assembly 3 is provided with a fourth latch hole 32 at one end close to the second stick body 2, the second threaded sleeve 5 is provided with a fifth latch hole 53, and the second threaded tube 51 is provided with a sixth latch hole 54;

[0020] After the positioning tooth 52 is inserted into the tooth groove 43, the first latch hole 31, the second latch hole 44 and the third latch hole 45 are connected, and the fourth latch hole 32, the fifth latch hole 53 and the sixth latch hole 54 are connected;

[0021] The tooth groove 43 and the positioning tooth 52 can form a gear lock. When the first stick body 1 and the second stick body 2 need to be spliced, the connecting assembly 3 is first inserted into the first stick body 1 and the second stick body 2, and then the first threaded sleeve 4 is lowered close to the second threaded sleeve 5, and the first threaded tube 41 and the second threaded tube 51 are rotated to insert the positioning tooth 52 into the tooth groove 43. At this time, the two latches can be respectively inserted into the connecting hole formed by the first latch hole 31, the second latch hole 44 and the third latch hole 45 and the connecting hole formed by the fourth latch hole 32, the fifth latch hole 53 and the sixth latch hole 54;

[0022] Since the gear may break during the striking process, the structure is increased to improve its strength. The utility model can leave a gap when the first stick body 1 and the second stick body 2 are combined by inserting the positioning teeth 52 and the tooth grooves 43, so as to provide a buffer for the relative movement of the first stick body 1 and the second stick body 2 to prevent breaking.
