Description

Technical Field

[0001] This invention relates to manual threading tools, and more particularly to a manual threader. Background Technology

[0002] Currently, the threading of electrical wires, steel wires, and other cables is done manually or with the aid of power tools. Manual threading is inefficient, labor-intensive, difficult, and increases wire loss; power tools are expensive and costly, hindering widespread adoption. Therefore, developing a manual threader has become a pressing issue for those skilled in the art. Summary of the Invention

[0003] The present invention addresses the above-mentioned shortcomings by providing a manual threader.

[0004] The above-mentioned objective of the present invention is achieved by the following technical solution: a manual threader, comprising a fixed housing and a movable housing, wherein the fixed housing is provided with a first threading channel and the movable housing is provided with a second threading channel, and a self-locking elastic clip assembly for feeding wire is installed in both the first threading channel and the second threading channel.

[0005] Furthermore, the fixed sleeve and the movable sleeve are tubular.

[0006] Furthermore, the fixed sleeve and the movable sleeve are interlocked, and the interlocking ends of the two are provided with anti-detachment locking positions that limit each other.

[0007] Furthermore, guide cylinders are installed in both the first and second threading channels.

[0008] Furthermore, the wire feeding self-locking elastic clamp assembly includes a pair of clamping blocks, with arc-shaped clamping teeth on the inner side of the clamping blocks, forming a V-shaped wire inlet between the arc-shaped clamping teeth of the two clamping blocks, and one end of the outer side of the clamping block is fixed in the first wire threading channel by a torsion spring, or fixed in the guide cylinder.

[0009] Furthermore, the clamping block is provided with a dovetail groove, and the arc-shaped clamping teeth are provided with dovetail ends and are engaged with the dovetail groove of the clamping block.

[0010] Furthermore, a take-up self-locking elastic clamp assembly is provided on one side of the wire feeding self-locking elastic clamp assembly. The take-up self-locking elastic clamp assembly has the same structure as the wire feeding self-locking elastic clamp assembly and is installed on the same axis, but in opposite directions. A wire feeding and take-up switching assembly is provided between the wire feeding self-locking elastic clamp assembly and the take-up self-locking elastic clamp assembly.

[0011] Furthermore, the wire feeding and take-up switching assembly includes a switching push shaft, a wire feeding side top block, and a take-up side top block. The clamping block has a protrusion on one side of its V-shaped wire inlet for the wire feeding side top block and the take-up side top block to open the clamping block (so that the V-shaped wire inlet is in an open state). The two ends of the switching push shaft are connected to keycaps. The two sides of the switching push shaft are respectively provided with a wire feeding side inclined push block and a take-up side inclined push block. The wire feeding side top block is provided with a wire feeding side inclined groove that cooperates with the wire feeding side inclined push block. The take-up side top block is provided with a take-up side inclined groove that cooperates with the take-up side inclined push block. The wire feeding side inclined groove and the take-up side inclined groove are staggered.

[0012] Furthermore, an extension tube is connected between the movable sleeve and the fixed sleeve, with the front end of the extension tube sleeved to the movable sleeve and the rear end of the extension tube sleeved to the fixed sleeve.

[0013] Furthermore, the extended tube is provided with a guide tube.

[0014] The advantages of this invention compared to the prior art are: the manual threading tool of this invention not only avoids threading by hand, but also is simple to operate, greatly improves threading efficiency, is low in cost, and is easy to popularize. Attached Figure Description

[0025] The invention will now be described in further detail with reference to the accompanying drawings.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, a manual threader includes a fixed housing 1 and a movable housing 2, both of which are tubular and interlocked. The interlocking ends of the fixed housing 1 and movable housing 2 are provided with mutually limiting anti-disengagement locking positions 3. Figures 4 to 6 As shown, the fixed housing 1 has a first threading channel 4, and the movable housing 2 has a second threading channel 5. The front end of the second threading channel 5 is connected to an outlet pipe 10. Guide cylinders 6 and self-locking elastic clamp assemblies 7 are installed in both the first and second threading channels 4 and 5, respectively. Figure 5 , Figure 6 As shown, the wire feeding self-locking elastic clamp assembly 7 includes a pair of clamping blocks 701. The inner side of the clamping blocks 701 is provided with arc-shaped clamping teeth 702. A V-shaped wire inlet 705 is formed between the arc-shaped clamping teeth 702 of the two clamping blocks 701. One outer end of the clamping block 701 is fixed in the first wire threading channel 4 by a torsion spring 706, or fixed in the guide cylinder 6. The clamping block 701 is provided with a dovetail groove 703. The arc-shaped clamping teeth 702 are provided with dovetail ends 704, which are engaged with the dovetail groove 703 of the clamping block 701.

[0027] In another embodiment, such as Figure 5 , Figure 6 As shown, a take-up self-locking elastic clamp assembly 8 is provided on one side of the wire feeding self-locking elastic clamp assembly 7. The take-up self-locking elastic clamp assembly 8 has the same structure as the wire feeding self-locking elastic clamp assembly 7 and is installed on the same axis, but in opposite directions. A wire feeding / take-up switching assembly 9 is provided between the wire feeding self-locking elastic clamp assembly 7 and the take-up self-locking elastic clamp assembly 8. Figures 4-6 ,as well as Figures 7-9 As shown, the wire feeding and take-up switching assembly 9 includes a switching push shaft 901, a wire feeding side top block 902, and a take-up side top block 903. The clamping block 701 has a protrusion on one side of its V-shaped wire inlet for the wire feeding side top block 902 and the take-up side top block 903 to push open the clamping block 701 (so that the V-shaped wire inlet is in an open state). The two ends of the switching push shaft 901 are connected to the keycaps 904. The two sides of the switching push shaft 901 are respectively provided with a wire feeding side inclined push block 905 and a take-up side inclined push block 906. The wire feeding side top block 902 has a wire feeding side inclined groove 907 that cooperates with the wire feeding side inclined push block 905. The take-up side top block 903 has a take-up side inclined groove 908 that cooperates with the take-up side inclined push block 906. The wire feeding side inclined groove 907 and the take-up side inclined groove 908 are staggered.

[0028] In yet another embodiment, such as Figure 10 As shown, an extension tube 11 is connected between the movable sleeve 2 and the fixed sleeve 1. The front end of the extension tube 11 is sleeved with the movable sleeve 2, and the rear end of the extension tube 11 is sleeved with the fixed sleeve 1. A guide tube 12 is provided in the extension tube 11.

[0029] When the wire is fed in, the wire feeder is first switched to the wire feeding state by the wire feeder / take-up switching component 9 (i.e., the clamping block of the take-up self-locking elastic clamp component 8 is opened, and the clamping block of the wire feeder self-locking elastic clamp component 7 is closed). Before operation, the wire is sequentially threaded from the rear end of the fixed housing 1 into the first wire feeding channel 4 and the second wire feeding channel 5, passing sequentially through the open take-up self-locking elastic clamp component 8 and the closed wire feeder self-locking elastic clamp component 7 in the first wire feeding channel 4, and the open take-up self-locking elastic clamp component 8 and the closed wire feeder self-locking elastic clamp component 7 in the second wire feeding channel 5, and finally led out from the outlet tube 10 at the front end of the second wire feeding channel 5. During operation, hold the fixed housing 1 with one hand and the movable housing 2 with the other, repeatedly pushing and pulling the movable housing 2 back and forth. When pushing the movable housing 2 out, the two clamps of the self-locking elastic clamp assembly 7, which is in a closed state, remain tightly closed, thus clamping the wire and feeding it forward a short distance. When pulling the movable housing 2 back, the two clamps of the self-locking elastic clamp assembly 7 can temporarily loosen under the pushing force of the wire and the action of the torsion spring, causing the movable housing 2 to retract, but the wire remains stationary. By repeating this action (repeatedly pushing and pulling the movable housing 2 back and forth), the wire can be continuously fed forward.

[0030] During take-up, the cable threader is switched to the take-up state via the take-up / take-up switching component 9 (i.e., the clamping block of the take-up self-locking elastic clamp component 8 is closed, and the clamping block of the take-up self-locking elastic clamp component 7 is opened). Before operation, the cable is sequentially threaded from the front end of the movable housing 2 into the second threading channel 5 and the first threading channel 4, passing sequentially through the open take-up self-locking elastic clamp component 7 and the closed take-up self-locking elastic clamp component 8 in the second threading channel 5, and the open take-up self-locking elastic clamp component 7 and the closed take-up self-locking elastic clamp component 8 in the first threading channel 4, and finally exiting from the rear port of the first threading channel 4. During operation, hold the fixed sleeve 1 with one hand and the movable sleeve 2 with the other, repeatedly pushing and pulling the movable sleeve 2 back and forth. When pulling the movable sleeve 2 back, the two clamps of the self-locking elastic clamp assembly 8, which is in a closed state, remain tightly closed, thus clamping the wire and pulling it back a short distance. When pushing the movable sleeve 2 out, the two clamps of the self-locking elastic clamp assembly 8 can temporarily loosen under the pushing force of the wire and the action of the torsion spring, allowing the movable sleeve 2 to be pulled forward, but the wire remains stationary. By repeating this action (repeatedly pushing and pulling the movable sleeve 2 back and forth), the wire can be continuously pulled back.

[0031] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
