[0032] Referring to Figs. 2-3 This is the second embodiment of the utility model, and is based on the previous embodiment.

[0033] Specifically, one side of the top of the second pipe 3 is fixedly connected with a limiting plate 10, and one side of the top of the first pipe 1 is fixedly connected with a retaining frame 11 which is slidably connected with the surface of the limiting plate 10.

[0034] The limiting plate 10 is fixed to the top of the second pipe 3, and the surface is slidably connected with the inside of the retaining frame 11, and since the retaining frame 11 is fixed to the first pipe 1, when the second pipe 3 moves in the first pipe 1, the limiting plate 10 is driven to move in the retaining frame 11, so as to ensure that the second pipe 3 will not overturn when moving, and the effect of guiding and providing stable movement of the second pipe 3 is achieved.

[0035] Specifically, the bottom of the first pipeline 1 is fixedly connected with negative magnetic 12 on both sides, and the bottom of the third pipeline 4 is fixedly connected with positive magnetic 13 on both sides.

[0036] The negative magnetic 12 and the positive magnetic 13 are strong magnets. When the user does not need to use the third pipeline 4 and fold it, the third pipeline 4 can be turned over and the positive magnetic 13 is attached to the negative magnetic 12. The strong attraction is generated by the principle of positive and negative attraction. The third pipeline 4 is stably fixed in the folded position, thereby greatly reducing the occupied space and facilitating storage and storage.

[0037] Specifically, one side of the inside of the second pipeline 3 is fixedly connected with a second threaded connector 31 that can be used for secondary assembly of a gun head. A sealing groove 14 is provided between the second threaded connector 31 and the second pipeline 3. One side of the inside of the third pipeline 4 is fixedly connected with a sealing ring 15 that is used for sealing after being combined with the second pipeline 3 and cooperating with the sealing groove 14. One side of the inside of the sealing ring 15 is fixedly connected with a sealing ring 16 that is used for sealing after being attached to the second threaded connector 31.

[0038] The second threaded connector 31 can be connected with different water gun nozzles when the third pipeline 4 is not used, provided that the nozzles match the thread width of the second threaded connector 31. When the third pipeline 4 is combined with the second pipeline 3 for extended use, the sealing groove 14 is provided at the end of the second pipeline 3 and the second threaded connector 31. The third pipeline 4 drives the sealing ring 15 to attach to the inside of the sealing groove 14. However, the third pipeline 4 also drives the sealing ring 15 and the sealing ring 16 to be inserted into the inside of the second threaded connector 31 and tightly attached to the inner wall of the second threaded connector 31, achieving a double sealing effect. The sealing effect of the third pipeline 4 and the second pipeline 3 after being clamped is improved, and the possibility of water leakage between the third pipeline 4 and the second pipeline 3 is prevented.

The tooth block 18 is fixed to the top of the third pipeline 4. When the third pipeline 4 is turned over and clamped at the end of the second pipeline 3, the third pipeline 4 is quickly clamped and fixed in cooperation with the positioning assembly 6.

[0041] Specifically, one side of the tooth block 18 is fixedly connected with a reinforcing block 19, and the bottom of the reinforcing block 19 is fixedly connected with the second pipeline 3.

[0042] The reinforcing block 19 is fixed between the second pipeline 3 and the tooth block 18, and the connecting strength between the tooth block 18 and the second pipeline 3 can be improved by the reinforcing block 19, and the service life of the tooth block 18 is improved.

[0043] Embodiment 3:

[0044] Referring to Figs. 1-4 As a third embodiment of the utility model, the embodiment is based on the previous two embodiments.

[0046] When the user needs to disassemble and fold the clamped third pipeline 4, the pressing plate 604 can be pressed down, at this time the push rod 603 drives the clamping plate 602 to move downward and compresses the spring 601, and the clamping plate 602 after descending will gradually separate from the surface of the tooth block 18, then the user can disassemble and fold the third pipeline 4, thereby improving the use convenience, and the tooth block 18 is provided with a slot opening that is matched with the push rod 603, preventing the tooth block 18 and the push rod 603 from being limited by pressing, so that the tooth block 18 cannot be clamped to the clamping plate 602.

[0047] Specifically, the clamping plate 602 is fixedly connected with sliding blocks 605 on the front and back sides, and the inside of the positioning shell 5 is provided with limiting grooves 606 for sliding use of the sliding blocks 605.

[0048] Through the sliding connection of the sliding blocks 605 and the limiting grooves 606, the sliding blocks 605 are limited to move in the limiting grooves 606 when the clamping plate 602 moves, thereby ensuring the stability of the clamping plate 602 when moving up and down.
