Description

CROSS-REFERENCE TO RELATED APPLICATION(S) This application claims priority to Chinese Patent Application No. 202422670925.9 filed with the China National Intellectual Property Administration (CNIPA) on Nov. 1, 2024, the disclosure of which is incorporated herein by reference in its entirety. TECHNICAL FIELD The present application relates to the technical field of stem-removing tools, and more particularly, to a stem remover. BACKGROUND Stem-removing tools are used to remove the stems from vegetables or fruits, to prevent direct contact between nails and the interior of vegetables or fruits, which not only enhances hygiene to a certain extent and protects the nails, but also makes the appearance of the vegetables and fruits after stem removal relatively beautiful, and even improves the efficiency of stem removal. Existing stem removers usually do not have the locking function and remain in a normally open state, which not only poses a safety hazard but also is unfavorable for storage. SUMMARY The objective of the present application is to overcome the problems of safety hazards and inconvenient storage caused by the lack of a locking function in existing stem removers, and to provide a stem remover that may be locked in a closed state when not in use. This not only improves the safety factor but also saves storage space and enhances the convenience of storage. In order to achieve the above objective, the technical solutions adopted by the present application are as follows. A stem remover is provided. The stem remover includes a first clamp body, a second clamp body and a pin shaft. The first clamp body is rotatably connected to the second clamp body through the pin shaft. The stem remover further includes a locking structure movably mounted on the first clamp body and/or the second clamp body. The stem remover in the present application achieves the stem-removing function in a manner of clamping the root and stem parts of fruits and vegetables by using the end of the first clamp body and the end of the second clamp body, and then pulling them out. The first clamp body is rotatably connected to the second clamp body through the pin shaft, thereby facilitating the adjustment of the distance between the two clamp bodies, and thus facilitating stem removal after an acting force is exerted on the root and stem. Compared with the stem remover in the related art, the stem remover of the present application adds a function of locking when the stem remover is in a closed state, which is achieved specifically through the locking structure. When locked, the first clamp body and the second clamp body cannot be opened, so the first clamp body and the second clamp body may be maintained in a locked state when closed. When unlocked, the first clamp body and the second clamp body may be freely opened or closed. The locking structure can also achieve the locking and unlocking functions of the first clamp body and the second clamp body in other manners. Further, the locking structure includes a locking plate and a torsion spring, the torsion spring is sleeved on the pin shaft, two ends of the torsion spring abut against opposite inner sides of the first clamp body and the second clamp body, respectively, the locking plate is located between the first clamp body and the second clamp body and is provided with a movable hole penetrating through the locking plate, the pin shaft is located in the movable hole, two ends of the pin shaft are disposed to protrude beyond the locking plate, and the locking plate is movable back and forth relative to the pin shaft. In a locked state, the torsion spring is compressed, the locking plate is located at a first position and forms a rotation limit for the first clamp body and the second clamp body, and the first clamp body and the second clamp body are kept closed. In an unlocked state, the locking plate is located at a second position, and the torsion spring may push the first clamp body and the second clamp body to open outwards. The cooperation between the locking plate and the torsion spring enables the locking or unlocking of the first clamp body and the second clamp body. In one or more embodiments, the torsion spring is mounted on the pin shaft. When the stem remover is in the closed state, that is, the first clamp body and the second clamp body are closed, the torsion spring is in a stressed and compressed state. In this case, if the locking plate is located at the first position, since the first clamp body and the second clamp body are limited by the locking plate and no rotation space exists, then the stem remover is locked, and the first clamp body and the second clamp body are kept closed. Instead, if the locking plate is located at the second position, an avoidance is formed for rotating ends of the first clamp body and the second clamp body, and a rotatable space exists between the first clamp body and the second clamp body, then under the drive of the elastic restoring force
