Description

Technical field:

[0001] The invention relates to a slingshot auxiliary processing device, in particular to a slingshot rubber band binding device. Background technology:

[0002] The rubber band tying device of a slingshot is a tool that slingshot users often use. When the rubber band of a slingshot needs to be replaced, the rubber band tying device needs to be used to pull the rubber band of the slingshot to a taut state so as to tie and fix it. Most of the existing rubber band tying devices for slingshots have a complex structure, and the operation steps are cumbersome to use. The rubber band tying process takes a long time and is inefficient. In addition, most of the existing rubber band tying devices are large in size and inconvenient to carry. When people go out to use slingshots, if they encounter a situation where the rubber band needs to be replaced, they cannot get timely processing. Summary of the invention:

[0003] The invention provides a slingshot rubber band tying device, which has an ingenious and reasonable structural design, simple operating steps and a small volume, and solves the problems existing in the prior art.

[0004] The technical solution adopted by the present invention to solve the above technical problems is:

[0005] A slingshot rubber band tying device comprises a base, a clamping arm is arranged on the base, a clamping surface is arranged on the clamping arm, the clamping surface is arranged at an angle, and also comprises a paddle installed on the clamping arm or the base, the paddle can be reset and rotated with the installation point as the axis through a spring, and the paddle achieves clamping by cooperating with the inclined surface of the clamping surface.

[0006] The present invention is further configured as follows: a leather bag fixing device is also arranged on the base.

[0007] The present invention is further configured as follows: the clamping arm comprises a vertical support arm arranged on the base and a horizontal clamping arm connected to the vertical support arm, and an inclined clamping surface is arranged at the bottom of the horizontal clamping arm.

[0008] The present invention is further configured as follows: the paddle is repositionably rotatably mounted on the inner side of the vertical support arm, the top of the paddle abuts against the clamping surface, and the height of the paddle is greater than the distance from the lowest point of the clamping surface to the base.

[0009] The present invention is further configured as follows: a suction cup is arranged at the bottom of the base.

[0010] The present invention adopts the above structure and has the following advantages:

[0011] The rubber band tying device has an ingenious structure, and the operation steps for fixing the rubber band are simple, which greatly shortens the rubber band tying time and improves efficiency; the rubber band tying device has a simple structure, and the automatic reset paddle and the inclined surface of the clamping surface cooperate to achieve the clamping of rubber bands of different thicknesses, and finally achieve the purpose of tying the rubber band independently. It is not easy for parts to be damaged in long-term use, and the service life is long; the connection design between the various parts of the device is reasonable, the production cost of the parts is low, the assembly is convenient and quick, and it is easy to promote and use; the whole device is small in size, and people can easily put the device into a bag and carry it with them when they go out, so that the slingshot rubber band can be replaced in time when used outdoors. Description of the drawings:

[0012] Figure 1 It is a structural schematic diagram of the present invention.

[0013] Figure 2 It is a schematic diagram of the clamping arm structure of the present invention.

[0014] In the figure, 1, base, 2, clamping surface, 3, pick, 4, fixing block, 5, fixing protrusion, 6, vertical support arm, 7, horizontal clamping arm, 8, suction cup. Specific implementation method:

[0015] In order to clearly illustrate the technical features of the present solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0016] like Figure 1-2 As shown in the figure, a slingshot rubber band tying device includes a base 1, a clamping arm is arranged on the base 1, a clamping surface 2 is arranged on the clamping arm, the clamping surface 2 is arranged at an angle, and also includes a paddle 3 installed on the clamping arm or the base 1, the paddle 3 can be reset and rotated with the installation point as the axis through a spring, and the paddle 3 achieves clamping by cooperating with the inclined surface of the clamping surface 2.

[0017] A leather bag fixing device is also provided on the base 1 .

[0018] The leather bag fixing device comprises a fixing block 4 having the same height as the clamping surface 2, on which a fixing protrusion 5 matching with the positioning hole of the leather bag is arranged. When fixing the leather bag, the fixing protrusion 5 can be directly inserted into the positioning hole for fixing.

[0019] The clamping arm is a vertical support arm 6 arranged on the base 1 and a horizontal clamping arm 7 connected to the vertical support arm 6 , and an inclined clamping surface 2 is arranged at the bottom of the horizontal clamping arm 7 .

[0020] The paddle 3 is repositionably mounted on the inner side of the vertical support arm 6 , the top of the paddle 3 is in contact with the clamping surface 2 , and the height of the paddle 3 is greater than the distance from the lowest point of the clamping surface 2 to the base 1 .

[0021] A suction cup 8 is provided at the bottom of the base 1 .

[0022] When tying the rubber band: fix the base 1 on the desktop by the suction cup 8. Insert the rubber band between the clamping arm and the plectrum 3, and the part of the rubber band to be tied is located at the lower end of the inclined clamping surface 2. Since the clamping surface 2 is inclined, as the plectrum 3 rotates, the plectrum 3 and the clamping surface 2 of the clamping arm press the rubber band therein, so that one end of the rubber band can be fixed, and the rubber band tying process can be carried out by fixing the leather bag.

[0023] The above specific implementation manner cannot be used as a limitation on the protection scope of the present invention. For those skilled in the art, any substitution, improvement or change made to the implementation manner of the present invention falls within the protection scope of the present invention.
