[0060] During the construction process, it is usually necessary to install and fix two or more objects into one object, such as welding two iron plates into one iron plate. In this process, multiple people are needed to connect and tighten the two iron plates, and then start welding to prevent dislocation during the welding process.

[0061] For single-person construction work, using clamps or the like to temporarily fasten the clamped object often leads to safety issues, and the clamps are sometimes difficult to remove from the clamped object.

[0062] The present application provides a fastening device that can be installed quickly, aiming to solve the technical problems in the prior art that the fastening installation requires multiple people, consumes manpower, is not reliable, and is difficult to remove after the device is fastened. The present application uses a clamping plate on an elastic clamp and a bolt on the clamping plate to fasten the clamped object safely and stably, and the strip grooves provided on the clamping plate and the round balls in the strip grooves can make it easy to remove the clamping device from the clamped object.

[0063] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0064] Figures 1 to 4 A fastening device that can be quickly installed is provided in an embodiment of the present application.

[0065] The elastic component 1 and the clamping component 2 are fixedly connected by bonding, welding or the like, and the clamping component 2 is connected with a fixing bolt 3, wherein the clamping component 2 and the fixing bolt 3 are detachably connected by means of thread, latch, clamping or the like; the elastic component 2 includes an elastic clip 101, and the elastic clip 101 and the first clamping plate 201 and the second clamping plate 202 in the clamping component 2 are independently fixedly connected, and the elastic clip 101 is used to adjust the opening and closing of the first clamping plate 201 and the second clamping plate 202, so that the first clamping plate 201 and the second clamping plate 202 can clamp and fix objects of different thicknesses;

[0066] The first clamping plate 201 and the second clamping plate 202 are respectively provided with rectangular grooves 203 on their outer sides; the two rectangular grooves 203 are provided with corresponding circular holes 204;

[0067] like Figure 2 As shown, a rectangular groove 203 is provided on the opposite outer sides of the first clamping plate 201 and the second clamping plate 202, and a circular hole 204 is provided in the middle of each rectangular groove 203, wherein the circular hole 204 on the rectangular groove 203 of the first clamping plate 201 corresponds to the circular hole 204 on the rectangular groove 203 of the second clamping plate 202;

[0068] The fixing bolt 3 is movably connected with the first clamping plate 201 and the second clamping plate 202 through the circular hole 204; the first clamping plate 201 and the second clamping plate 202 are oppositely arranged on the inner side, respectively corresponding to the strip groove, and the round ball 207 is arranged in the strip groove.

[0069] The circular hole 204 allows the fixing bolt 3 to pass through and enables the fixing bolt 3 to be movably connected to the first clamping plate 201 and the second clamping plate 202. The fixing bolt 3 can further enable the first clamping plate 201 and the second clamping plate 202 to clamp the clamped object, which is convenient for subsequent operations. In order to facilitate the removal of the fastening device from the clamped object and prevent the fastening device from clamping the clamped object too tightly and the fastening device from being removed from the clamped object, strip grooves are provided on the relative inner sides of the first clamping plate 201 and the second clamping plate 202, and rolling balls 207 are installed in the strip grooves.

[0070] In another embodiment, the strip grooves include a first strip groove 205 and a second strip groove 206; the first strip groove 205 and the second strip groove 206 are respectively arranged on both sides of the rectangular groove 203; the first strip groove 205 and the second strip groove 206 are respectively provided with a plurality of round balls 207, and the plurality of round balls 207 can roll freely.

The round balls 207 can roll freely in the first strip groove 205 and the second strip groove 206.

[0072] In the specific implementation process, the elastic clamp 101 is used to open the first clamping plate 201 and the second clamping plate 202 to clamp and tighten the clamped object. The elastic force of the elastic clamp 101 causes the first clamping plate 201 and the second clamping plate 202 to temporarily tighten the clamped object. The fixing bolt 3 passes through the round hole 204 on the first clamping plate 201 and the second clamping plate 202, so that the first clamping plate 201 and the second clamping plate 202 temporarily tighten the clamped object for a second time. After the clamped object is tightened and installed, the fixing bolt 3 is loosened, and the first clamping plate 201 and the second clamping plate 202 are removed; if the clamped object is tightened too tightly due to the fixing bolt 3 for the second time, the ball 207 in the strip groove can roll freely between the clamped object and the clamping plate, and the fastening device can be removed from the clamped object.
