Abstract
Description
Technical Field
[0001] This utility model relates to the field of rebar tying technology, specifically a long-pole rebar tying tool. Background Technology
[0002] A rebar tying machine is a handheld, battery-powered tool for quickly tying rebars. It is constructed by inserting two intersecting rebars into a curved guide section at the end of the machine's main body. A wire feeder delivers wire from a wire reel mounted on the machine body, coils and feeds the wire at the guide section, and winds it around the two rebars into a loop. After winding the wire around the rebars, a wire cutting mechanism cuts the ends of the wire. A pair of twisting hooks from a wire twisting device picks up and rotates one end of the wire loop, thus twisting the wire and tightly binding it. The biggest advantages of a rebar tying machine are its speed and convenience, saving significant manpower and greatly reducing the labor intensity of workers. Therefore, it can meet most usage requirements and can be widely used in the construction industry to replace manual rebar tying.
[0003] Existing rebar tying machines require prolonged squatting and bending during operation, which puts a strain on the user's body and is inconvenient for tying rebar in areas inaccessible by the arm or at heights. Therefore, they do not meet the current needs. To address this, we have proposed a long-pole rebar tying tool. Utility Model Content

The inner side of the second transmission rod 208 is provided with a polygonal insertion hole, and the first transmission rod 207 is inserted into the inner side of the polygonal insertion hole. The first transmission rod 207 is rotatably connected to the telescopic slide rod 202. The second transmission rod 208 drives the first transmission rod 207 to rotate synchronously, thereby realizing the guidance and conveying of the iron wire by the first feeding pipe 203 and the second feeding pipe 204.
[0023] Please see Figure 2 and Figure 3 The telescopic slide rod 202 has multiple positioning holes 205 on one side, and a positioning module 206 is installed on one side of the storage sleeve rod 201. The positioning module 206 includes a mounting sleeve 211, a support spring 209 on the inner side of the mounting sleeve 211, and a positioning insert rod 210 on the inner side of the support spring 209. The mounting sleeve 211 is connected to the storage sleeve rod 201 by a thread. One end of the positioning insert rod 210 passes through the mounting sleeve 211 and the support spring 209 and is inserted into the inner side of one of the positioning holes 205.

As a result, the telescopic slide rod 202 slides axially inside the receiving sleeve rod 201 and simultaneously drives the second conveying pipe 204 to slide and extend relative to the first conveying pipe 203. This facilitates the adjustment of the length of the telescopic transmission unit 2, and the limiting angle plate 212 can limit the telescopic slide rod 202 to prevent the receiving sleeve rod 201 from separating from the telescopic slide rod 202.
[0028] After adjustment, the positioning rod 210 slides relative to the mounting sleeve 211 under the elastic support of the support spring 209 and automatically inserts into the inside of one of the positioning holes 205, which facilitates locking the storage sleeve rod 201 and the telescopic slide rod 202, keeping the telescopic transmission unit 2 stable during binding. When the power is turned on, a motor is provided inside the housing 101, and the output end of the motor is connected to the second transmission rod 208 through a coupling.
