Description

Control mechanism for adjusting and locking angle of push rod of mower Technical Field The application relates to the technical field of mowers, in particular to a control mechanism for adjusting and locking the angle of a push rod of a mowing machine. Background In the field of garden machinery, a mower is used as a common vegetation pruning device and is widely applied to the scenes such as lawns, slopes, farmlands and the like. In order to accommodate the demands of different terrains and operating postures, modern mowers are generally equipped with angle-adjustable push rod structures to improve operating comfort and work efficiency. The common push rod angle locking structure on the push rod of the mower mostly adopts a multi-stage positioning hole matched with a spring pin or a buckle type structure, however, the push rod angle locking structure cannot be directly adjusted at the position of the push rod and is easy to unlock under the vibration of the mower, although part of the high-end push rod structure can be unlocked through a steel wire pull rope, the unlocking transmission mode is always directly connected with the two sides of a button through the steel wire pull rope and is directly connected with an unlocking pull rod, so that a large force is required to overcome the spring force and lift the steel wire pull rope and a pin body for locking, and therefore, the problem is solved. The foregoing is provided merely for the purpose of facilitating understanding of the application and is not intended to represent the closest prior art to which the application pertains. Disclosure of Invention Based on the above, the application provides a control mechanism for adjusting and locking the angle of a push rod of a mower, which solves one of the technical problems. The technical scheme includes that the control mechanism comprises a mower main body part, push rod shells, buttons, a connecting rod structure and an angle locking structure, wherein the first rotating shaft is arranged on two sides of the mower main body part, the push rod shells are in rotating connection with the mower main body part through the first rotating shaft, the buttons are movably arranged on the push rod shells, the connecting rod structure comprises a first connecting rod and a second connecting rod which are in rotating connection, the first connecting rod and the second connecting rod are rotatably arranged in the push rod shells, two ends are separated from each other by a rotating point of the first connecting rod or the second connecting rod, one end close to the buttons is longer than the other end, the buttons are abutted to one end of the first connecting rod and can drive the first connecting rod to rotate, the angle locking structure is arranged between at least one group of the mower main body part and the push rod shells and used for locking the rotating angle of the push rod shells, and the second connecting rod can drive the angle locking structure to unlock or lock through rotation. In some embodiments, the angle locking structure comprises a locking plate and a locking shaft, wherein a plurality of lock holes are formed in the locking plate, the locking plate is fixedly arranged on one side of the mower main body part, and the second connecting rod can drive the locking shaft to be inserted into the lock holes through rotation to fix the angle of the push rod shell. In some embodiments, a spring is sleeved on the locking shaft to drive the locking shaft to always move towards the lock hole. In some embodiments, the locking plate forms an arc for mating with the rotational trajectory of the locking shaft. In some embodiments, a connecting plate is arranged at the rear end of the locking shaft, a notch is formed in the connecting plate, and the first rotating shaft penetrates through the notch and can rotate and slide in the notch. In some embodiments, a second rotating shaft is disposed on the inner side of the push rod housing, and the first link and the second link are rotatably disposed inside the push rod housing through the second rotating shaft. In some embodiments, a first limiting portion is disposed inside the push rod housing and is used for limiting a rotation range of the first link and the second link, so as to limit a maximum distance of the push button. In some embodiments, a second limit is provided inside the push rod housing for limiting a maximum distance of the push of the button. In some embodiments, two ends of the first connecting rod are respectively an abutting end and a first rotating end, the abutting end abuts against the upper portion of the button, two ends of the second connecting rod are respectively a second rotating end and a connecting end, the second rotating end is in mutual rotating connection with the first rotating end, and the connecting end is used for connecting a steel wire stay rope to be connected with the angle locking structure.
