Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is based on Japanese Patent Application No. 2023-004113 filed on Jan. 13, 2023 and Japanese Patent Application No. 2023-190932 filed on Nov. 8, 2023, the contents of which are incorporated herein by way of reference. TECHNICAL FIELD The present disclosure relates to a binding machine and a binding method. BACKGROUND ART It is known that a plant and the like are bound with a wire or the like by using a binding tool such as a staple. Patent Literature 1 describes an electric binding machine that includes a rechargeable power source detachably connected to a mounting shell. A binding machine described in Patent Literature 2 can perform binding by using the staple described in Patent Literature 1. Patent Literature 2 describes an example of such a staple. The staple includes a pair of left and right arms and a convex protrusion provided between the arms. Patent Literature 1: Chinese Patent Application Publication No. 111903423Patent Literature 2: European Patent No. 1839482 Patent Literature 1 discloses a binding machine that binds a plant and the like using the staple disclosed in Patent Literature 1. The staple and the like described in Patent Literature 2 restrain the relative movement of two objects, that is, a guide element (a first object) and a plant and the like (a second object), and thus the staple and the like correspond to a binding tool (a staple) for binding the two objects. Patent Literature 2 discloses that the plant and the like are inserted into a cavity provided in the binding tool when the binding is performed. However, Patent Literature 2 does not disclose a method for engaging a binding tool with a string or the like, which is a guide element, and thus does not consider the improvement of a work efficiency by engaging the guide element and the binding tool with each other easily or in a manner of being less likely to be disengaged from each other. Therefore, an example of the object of the present disclosure is to provide a binding machine and a binding method for improving a work efficiency by engaging a guide element and a binding tool with each other easily or in a manner of being less likely to be disengaged from each other. SUMMARY OF INVENTION There is provided a binding machine for binding a first object and a second object by using a staple that includes a first leg portion, a second leg portion, and a main body portion that connects the first leg portion and the second leg portion and that opens toward a forward direction. The binding machine includes: a first displacement portion configured to displace the first leg portion so as to surround the first object; a second displacement portion configured to displace the second leg portion such that the second object is surrounded by the first leg portion, the second leg portion, and the main body portion; and a guide portion configured to guide the first object in a direction approaching the first leg portion. The guide portion may include a wall portion that is configured to approach the first leg portion toward a rearward direction. The wall portion may be provided at a position separated from the first leg portion in an up-down direction intersecting an opening direction of the staple. The wall portion may be configured to intersect the first leg portion and is configured to extend from outside to inside of the first leg portion in a top view. The wall portion may be provided in an upper direction and a lower direction with respect to the first leg portion. The wall portion may be displaceable in a direction separated from the first leg portion. The binding machine may further include: a biasing portion configured to bias, toward the first leg portion, the first object that approaches the first leg portion along the wall portion. The first leg portion may include a first portion extending in the forward direction, a bent portion that is bent and connected to the first portion, and a tip end portion connected to the bent portion and extending in an outward direction separated from the first portion. The biasing portion may be configured to bias the first object toward the bent portion (in the forward direction). The biasing portion may include a pressing surface for pressing the first object in the forward direction and an elastic body for pressing the pressing surface in the forward direction. The biasing portion may be configured to retract the pressing surface by compressing the elastic body, and may be configured to insert the first object into a region surrounded by the first portion, the bent portion, the tip end portion, the wall portion, and the pressing surface in a top view by retracting. The first displacement portion may include a first inner wall portion configured to support the first portion. The wall portion may approach the first inner wall portion as advancing in a rearward direction so as to form an acute angle with the first inner wall portion in the top vi
