Technical Field
[0001] The utility model relates to the technical field of agricultural machinery, in particular to a grass trimmer. Background Art
[0002] A lawn mower is a handheld tool used to cut weeds in lawns, gardens, pastures, etc. In order to facilitate storage, existing lawn mowers are usually configured to be foldable, specifically, a rod body in the lawn mower is configured to be foldable, and when the lawn mower needs to be stored, the rod body is folded to reduce the space occupied by the lawn mower.
[0003] In the existing lawn mowers, a wire passes through the rod body. When the rod body is folded, the wire will also fold along with the rod body. When the wire is folded, it will protrude to the outside at the folded position of the rod body. When the lawn mower is changed from a folded state to a use state, the two sections of the rod body need to be aligned. At this time, the wire may be partially exposed outside the rod body due to the previous folding. It is necessary to manually stuff all the wires into the rod body and then align and fix the two sections of the rod body, which is time-consuming and laborious. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a lawn mower, which is used for an auxiliary wire to smoothly enter a rod body when the lawn mower is transformed from a storage state into a use state.
[0005] The utility model is realized by the following technical solutions:
[0006] A lawn mower, comprising:
[0007] Rod assembly;
[0008] A tail end assembly, with fixings disposed therein;
[0009] A wire, one end of which is connected to the tail end assembly and extends from the tail end assembly into the rod body assembly;
[0010] An elastic member, one end of which is fixedly connected to the fixing member, and the other end of which is connected to the wire, and the elastic member applies an elastic traction force to the wire in a direction toward the fixing member.
[0011] Furthermore, the tail end assembly includes a shell and a circuit assembly disposed in the shell, the wire is connected to the circuit assembly, and the fixing member is fixedly connected to the shell.
[0012] Furthermore, the shell is provided with a connecting column, and the fixing piece is threadedly connected to the connecting column.
[0013] Furthermore, one end of the elastic member connected to the fixing member is provided with a hook portion, and the hook portion is hooked on the fixing member;
[0014] And / or, the fixing member is a screw.
[0015] Furthermore, a plurality of the conductive wires are provided, and the conductive wires are connected with conductive wire binding bands, and the conductive wire binding bands bind the plurality of conductive wires.
[0016] Furthermore, one end of the elastic member connected to the wire is provided with a hook portion, and the hook portion is hooked on the wire or the wire binding band.
[0017] Furthermore, the elastic member is a spring, and when the elastic member is connected to the wire and the fixing member respectively, the elastic member is in a stretched state.
[0018] Further, the rod body assembly includes a first rod body, a second rod body and a stopper, the first rod body is hinged to the second rod body so that the first rod body and the second rod body can form a folded state and an open state, and the stopper is used to connect with the first rod body and the second rod body in the open state so that the first rod body and the second rod body are fixed to each other.
[0019] Furthermore, the wire extends through the first rod body and the second rod body, and when the first rod body and the second rod body are in a folded state, a portion of the wire located at the folded position of the first rod body and the second rod body is folded and exposed to the outside, and an outer periphery of a portion of the wire located at the folded position of the first rod body and the second rod body is coated with an insulating material.

[0021] Compared with the prior art, the advantages of the present invention are at least:
[0022] By arranging an elastic member to apply an elastic traction force to the wire in the direction of the fixing member, the tendency of pulling the wire toward the inside of the lawn mower rod can be maintained. When the lawn mower is in a folded state, the traction of the wire by the elastic member reduces the bulging of the wire at the folding point of the two rods. When the lawn mower is transformed from a folded state to a use state, when the two rods are aligned, the traction of the wire by the elastic member allows the wire to be relatively smoothly received into the two rods, thereby reducing the amount of the wire bulging out of the outside, alleviating or avoiding the bulging of the wire, reducing or avoiding the wire clamping phenomenon, and also reducing the risk of wire damage.
[0023] In addition, by arranging the elastic member to be in a stretched state after being connected to the wire and the fixing member respectively, the elastic member can continuously apply an elastic traction force to the wire in the direction of the fixing member, thereby ensuring the traction effect of the elastic member on the wire.

Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the utility model, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limitations on the utility model.
[0029] like Figures 1 to 3 As shown, a grass trimmer corresponding to a preferred embodiment of the utility model comprises a tail end assembly 1, a rod assembly 2, a guide wire 3, an elastic member 4 and a grass trimmer head (not shown).
[0030] The mowing head is arranged at one end of the rod assembly 2 and connected to the rod assembly 2, and the mowing head rotates when powered on to achieve the mowing operation. The mowing head is one of the common mowing machine parts, so it will not be described here.
[0031] Further references Figure 2 and Figure 3 The tail end assembly 1 includes a housing 12 and a circuit assembly 13 and a fixing member 11 disposed in the housing 12. The circuit assembly 13 is connected to the wire 3. The fixing member 11 can be fixedly installed inside the housing 12, for example, the fixing member 11 is fixedly connected to the housing 12. Specifically, the housing 12 is provided with a connecting column 14 fixedly connected to the fixing member 11, and the connecting column 14 and the main body of the housing 12 are an integrated structure. Among them, the connecting column 14 can be provided with a threaded hole, the fixing member 11 can be a screw, and the fixing member 11 is threadedly connected to the connecting column 14.
[0032] One end of the rod assembly 2 is connected to the mowing head, and the other end is connected to the tail assembly 1. The rod assembly 2 may include a first rod, a second rod, and a connecting assembly (not shown) connecting the first rod and the second rod, and the first rod and the second rod are hinged by the connecting assembly. For example, the connecting assembly includes a first part connected to the first rod and a second part connected to the second rod, one end of the first part is hinged to the second part, so that the first rod and the second rod are hinged; the other end of the first part can be connected to the second part through a stopper, so that when the first rod and the second rod are aligned, the first part and the second part remain relatively fixed, and at this time, the first rod and the second rod are relatively fixed to form a long rod used when the mower is working. Among them, the connecting assembly can be a hoop, the first part and the second part are two half rings in the hoop, one end of the first part and the second part can be hinged by a bolt (the bolt is clearance-matched with the first part and the second part), a pin and other parts, and the other end of the first part and the second part is fixed by a fastener such as a bolt (the bolt is threadedly connected to the first part and / or the second part).
[0033] When the first rod body and the second rod body need to be folded, the stopper is separated from the first part and the second part, so that the rod body assembly 2 can be folded and stored to form a folded state. When the lawn mower needs to be used, the first rod body and the second rod body are adjusted to overlap axially and form an axially aligned state. At this time, the stopper is connected to the first part and the second part to achieve the fixation between the first rod body and the second rod body, so that the first rod body and the second rod body form a complete long rod of the lawn mower.
[0034] One end of the wire 3 is connected to the tail end assembly 1, for example, connected to the circuit assembly 13 in the tail end assembly 1, and then the wire 3 extends in the rod body assembly 2 to pass through the first rod body and the second rod body, and the other end of the wire 3 passes through the rod body assembly 2 to connect with the grass trimming head. The tail end assembly 1 is electrically connected to the grass trimming head through the wire 3, so that the circuit assembly 13 can supply power to the grass trimming head and transmit instructions through the wire 3, such as controlling the working mode of the grass trimming head, starting the grass trimming head, stopping the grass trimming head, etc. Among them, the wire 3 can be one or more, and when the wire 3 is set to be multiple, the multiple wires 3 can be bundled together using a wire tie.
[0035] When the first rod and the second rod are folded, the portion of the wire 3 located at the folded position of the first rod and the second rod will be folded along with the first rod and the second rod. Figure 3 , the wire 3 is connected to one end of the elastic member 4, and the other end of the elastic member 4 is connected to the fixing member 11. The elastic member 4 can generate elastic deformation between the fixing member 11 and the wire 3, so that the elastic member 4 can apply an elastic traction force to the wire 3 toward the fixing member 11. When the first rod body and the second rod body are folded, the elastic member 4 maintains a pulling force on the wire 3 to pull the wire 3 toward the inside of the mower, that is, toward the fixing member 11 in the tail end assembly 1, thereby preventing the wire 3 from bulging outwards due to the friction or resistance between the wire 3 and the inner wall of the first rod body and / or the second rod; when the first rod body and the second rod body are transformed from the folded state to the use state, the first rod body rotates relative to the second rod body, and the wire 3 has a tendency to be pushed outwards by the first rod body and the second rod body due to the friction between the wire 3 and the inner wall of the first rod body and the second rod body, but because the elastic member 4 applies an elastic pulling force toward the fixing member 11 to the wire 3, the wire 3 with a tendency to be pushed outwards is pulled back into the rod body by the elastic member 4, so that the first rod body and the second rod body are smoothly aligned and fixed, reducing or avoiding the wire clamping phenomenon of the wire 3, and also reducing the risk of damage to the wire 3; in addition, when the first rod body and the second rod body are folded, the wire 3 can also be made to fit the first rod body and the second rod body at the folding part of the first rod body and the second rod body to form a smooth transition, avoiding the wire 3 from having a sharp angle structure at the connection between the first rod body and the second rod body, and reducing the risk of damage to the wire 3.
[0036] In some specific embodiments, hooks 41 may be provided at opposite ends of the elastic member 4, the hook 41 at one end of the elastic member 4 is hooked on the fixing member 11, and the hook 41 at the other end of the elastic member 4 is hooked on the wire 3. A wire binding band is tied to the wire 3, and the hook 41 at one end of the elastic member 4 connected to the wire 3 is hooked on the wire binding band.
[0037] When one end of the elastic member 4 is connected to the fixing member 11 and the other end is connected to the wire 3, the elastic member 4 can be in an elastic deformation state, that is, in a stretched state, so that the elastic member 4 maintains an elastic traction force on the wire 3. Specifically, the elastic member 4 can be a spring, and when the elastic member 4 is connected to the wire 3 and the fixing member 11 respectively, the elastic member 4 is stretched, that is, the length of the elastic member 4 at this time is greater than the length of the elastic member 4 in the relaxed state.
[0038] In some specific embodiments, when the first rod body and the second rod body are folded, the portion of the wire 3 located at the folded position of the first rod body and the second rod body is exposed to the outside. In order to prevent the portion of the wire 3 exposed to the outside from being damaged due to scratches, which may cause leakage of the wire 3, the portion of the wire 3 located at the folded position of the first rod body and the second rod body, that is, the outer periphery of the portion of the wire 3 exposed to the outside is coated with an insulating material. The insulating material protects the outer skin of the wire 3, thereby preventing the wire 3 from being damaged due to scratches.
[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
