Description

Technical Field

[0001] This utility model relates to the field of mechanical tool technology, and in particular to an adjustable motor fixing clamp for model aircraft. Background Technology

[0002] When disassembling and assembling motors on model airplanes and other similar devices, some motors are small or obstructed by components connected to them (such as propellers), making it impossible to hold them firmly with fingers. Therefore, special clamping pliers are needed to hold and secure the motors and their components for easy assembly and disassembly. Existing clamping pliers can hold most motors of similar size, but they are still unable to securely hold some specially designed small motors or small motors, which urgently need improvement. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this utility model provides an adjustable motor clamp for model aircraft, comprising a pair of clamping arms with chucks, several elastic protective clamping blocks, and a main connecting bolt. The pair of clamping arms are connected by the main connecting bolt and rotated together. The several elastic protective clamping blocks are respectively mounted on the chucks of the pair of clamping arms. Each chuck of the pair of clamping arms has a small chuck. A connecting block is fixedly mounted on one end of the small chuck, and a countersunk hole is formed at the other end of the small chuck. A threaded hole penetrating the connecting block is formed in the countersunk hole. A groove matching the connecting block is formed on the end face of the chuck, and a threaded hole is also formed in the groove. The small chuck is set in the groove through the connecting block and is detachably connected to the chuck by a connecting screw.

[0004] Using the above technical solution, when it is necessary to clamp small motors or motors of special size, since the diameter of the normal chuck is too large, a pair of small chucks can be removed, thereby reducing the minimum diameter that the chuck can clamp. After removing the small chucks, clamping can be performed smoothly. By setting a connecting block on the small chuck, the internal stress of the small chuck when it is installed on the chuck can be increased, thus protecting the connecting screws.

[0005] Further features of this invention: the clamp has an installation groove that matches the elastic protective clamp block; both sides of the clamp are provided with installation cover plates for limiting the elastic protective clamp block; the installation cover plates are connected to the clamp by screws; the plurality of elastic protective clamp blocks are also provided with elastic protective edges; both ends of the elastic protective edges are fixedly connected to the elastic protective clamp blocks.

[0006] By adopting the above technical solution, since the clamp has an installation groove that matches the elastic protective clamp, and both sides of the clamp are provided with installation cover plates for limiting the elastic protective clamp, the installation cover plates are connected to the clamp by screws, and the elastic protective clamps are also provided with elastic protective edges, both ends of which are fixedly connected to the elastic protective clamps. When clamping a small-diameter motor or motor, the elastic protective edges can prevent the parts from being pinched.

[0007] A further feature of this invention is that one end of the small chuck is provided with a small clamping groove for clamping small-radius bolts and nuts, and the countersunk hole is located within the small clamping groove.

[0008] By adopting the above technical solution, since one end of the small clamp is also provided with a small clamping groove for clamping small radius bolts and nuts, and the countersunk hole is set in the small clamping groove, the applicable range of the fixing clamp is broadened.

[0009] A further feature of this invention is that an arc-shaped clamping groove for holding a metal column is provided on the clamp near the main connecting bolt.

[0010] By adopting the above technical solution, since an arc-shaped clamping groove for clamping metal columns is opened on the clamp head near the main connecting bolt, the applicability of the fixing clamp is further broadened.

[0011] A further feature of this invention is that the pair of clamping arms are provided with several through holes.

[0012] By adopting the above technical solution, since several through holes are also opened on the pair of clamping arms, the weight of the fixing clamp is reduced and the feel of use is improved. Attached Figure Description

Detailed Implementation

[0017] like Figure 1-3 As shown, an adjustable motor clamp for model aircraft includes a pair of clamping arms 2 with chucks 1, several elastic protective clamping blocks 3, and a main connecting bolt 4. The pair of clamping arms are connected by the main connecting bolt and rotated together. The several elastic protective clamping blocks are respectively installed on the chucks of the pair of clamping arms. Each chuck of the pair of clamping arms is provided with a small chuck 5. A connecting block 6 is fixedly provided at one end of the small chuck. A countersunk hole 7 is opened at the other end of the small chuck. A threaded hole 8 is opened in the countersunk hole and passes through the connecting block. A groove 9 matching the connecting block is opened on the end face of the chuck. A threaded hole is also provided in the groove. The small chuck is set in the groove through the connecting block and is detachably connected to the chuck by a connecting screw 16.

[0018] When clamping small motors or motors of special sizes, since the diameter of the normal chuck is too large, a pair of small chucks can be removed to reduce the minimum diameter that the chuck can clamp. After removing the small chucks, clamping can be performed smoothly. By setting connecting blocks on the small chucks, the internal stress of the small chucks when they are installed on the chuck can be increased, thus protecting the connecting screws.

[0019] The clamp has a mounting groove 10 that matches the elastic protective clamp. Both sides of the clamp are provided with mounting cover plates 11 for limiting the elastic protective clamp. The mounting cover plates are connected to the clamp by screws. The elastic protective clamps are also provided with elastic protective edges 12. Both ends of the elastic protective edges are fixedly connected to the elastic protective clamps.

[0020] Because the chuck has a mounting groove that matches the elastic protective clamping block, and mounting cover plates for limiting the elastic protective clamping block are provided on both sides of the chuck, the mounting cover plates are connected to the chuck by screws, and the elastic protective clamping blocks are also provided with elastic protective edges. Both ends of the elastic protective edges are fixedly connected to the elastic protective clamping blocks. When clamping a small-diameter motor or motor, the elastic protective edges can prevent the parts from being pinched and damaged.

[0021] One end of the small chuck is also provided with a small clamping groove 13 for clamping small radius bolts and nuts, and the countersunk hole is provided in the small clamping groove.

[0022] Since one end of the small clamp is also provided with a small clamping groove for clamping small-radius bolts and nuts, and the countersunk hole is set in the small clamping groove, the applicability of the fixing clamp is broadened.

[0023] An arc-shaped clamping groove 14 for clamping the metal column is provided on the clamp near the main connecting bolt.

[0024] The clamp has an arc-shaped groove for holding metal columns near the main connecting bolt, which further expands the applicability of the fixing clamp.

[0025] The pair of clamping arms also have several through holes 15.

[0026] Because the pair of clamping arms also have several through holes, the weight of the clamping clamp is reduced and the feel of use is improved.
