Description

TECHNICAL FIELD The disclosure belongs to the technical field of horticultural irrigation tools and, in particular, relates to a water outlet control structure of a water spray gun. See for example WO2020/239728. BACKGROUND The horticultural water spray gun is a tool specifically designed for horticultural irrigation and plant care. Its design allows users to easily control the direction and amount of water flow to meet the irrigation needs of different plants. In ancient times, people watered manually using simple irrigation tools, such as wooden barrels, water tanks, or pouring kettles. This method is inefficient and cannot meet the needs of large-scale horticulture. With the advancement of technology, people have started to use handheld water sprayers for irrigation. These tools, usually made of metal or plastic, allow more precise control of the water flow and increase the efficiency of irrigation. Hand-held sprayers, when irrigating, typically require the operator to continuously press on the spray head handle to ensure that the water is constantly sprayed. Continuously pressing the handle requires continuous force from the hand muscles, which can lead to fatigue and soreness over time, affecting the user's comfort and work efficiency. Continuously pressing the handle may cause excessive pressure on the finger joints, increasing the risk of joint pain and discomfort, especially for personnel who work continuously for a long time. It may also cause soft tissue injury of hand, such as tendonitis and tenosynovitis, and may require long-term rehabilitation in severe cases. In view of the above, the existing water spray guns have the problem of requiring long-term pressing during use, which can easily cause hand fatigue. SUMMARY In view of the above, the disclosure provides a water outlet control structure of a water spray gun capable of solving the problem that a conventional water spray gun needs to be pressed for a long time to easily cause hand fatigue during use. The disclosure is realized in that: The disclosure provides a water outlet control structure of a water spray gun comprising a water spray gun head and a pressing handle, the water spray gun head being configured to spray water flow, the pressing handle being configured to control a switch of the water flow, and the water spray gun head being rotatably connected to the pressing handle; the pressing handle is movably connected to a clamping piece; the water spray gun head is provided with a moving groove at a side wall; the moving groove comprises a first sliding groove, a second sliding groove, a third sliding groove, a fourth sliding groove, a first limiting block, and a second limiting block; and the clamping piece is slidably connected to the moving groove. The technical effects of a water outlet control structure of a water spray gun provided by the disclosure are as follows: by providing the water spray gun head, water can be sprayed to a specific position as required; by providing the pressing handle, the flow of the water flow can be controlled, so that the user can conveniently control the start and stop of the water flow to achieve a flexible operation; at the same time, the water source can be saved and the convenience and safety of the operation can be improved; by providing a clamping piece, the water spray of the water spray gun head can be automatically operated, thereby reducing the need for manual intervention and operation; automatic water spray can reduce the fatigue of operator's hands and avoid the discomfort of long-term holding. On the basis of the above technical scheme, the water outlet control structure of a water spray gun of the disclosure can also be improved as follows: Wherein the clamping piece comprises a clamping piece body, a sliding portion and a clamping portion; the sliding portion is fixedly connected to a head portion of the clamping piece body; the sliding portion is slidably connected to the moving groove; the clamping portion is fixedly connected to a tail portion of the clamping piece body; and the clamping piece body is movably connected to the pressing handle via the clamping portion. The advantageous effects of using the above improvement are: by providing the clamping portion, the pressing handle can be driven to be linked with the clamping piece body and the sliding portion, so as to achieve a flexible smooth outflow effect. Further, the first sliding groove is in communication with the second sliding groove; the first sliding groove is in communication with the third sliding groove; the third sliding groove is in communication with the fourth sliding groove; the fourth sliding groove is in communication with the second sliding groove; the first limiting block is configured to guide the extension direction of the first sliding groove and the second sliding groove; the second limiting block is configured to guide the extension direction of the third sliding groove; the fourth sliding groove and th
