DETAILED DESCRIPTION

[0031] ​​​With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0032] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application. Figures 1 to 5 The present application provides a technical solution: a fixing clamp, comprising a lower clamping plate 1 and an upper clamping plate 2, a clamp assembly is installed between the outer sides of the lower clamping plate 1 and the upper clamping plate 2, and the abutting surfaces of the lower clamping plate 1 and the upper clamping plate 2 are each provided with a rough layer 4 with irregular patterns;

[0033] In the above embodiment, the cooperation between the lower clamping plate 1, the upper clamping plate 2 and the clamp assembly on the opposite side can facilitate the use and also stably position the clamping, so that the fixing clamp can be easily opened and closed, and can stably position and clamp the target object, and can also meet the clamping needs of thicker objects, thereby effectively improving the practicality of the fixing clamp.

[0034] The clamp assembly in the embodiment is a structure for allowing the fixing clamp to be simply and stably used.

[0035] As shown in Figure 1 , Figure 2 and Figure 3 , the clamp assembly comprises a lower pressing block 301 fixed to the right side of the lower clamping plate 1, an upper pressing block 302 fixed to the right side of the upper clamping plate 2, a plurality of first connecting blocks 303 fixed to the top of the lower clamping plate 1, a plurality of second connecting blocks 304 fixed to the bottom of the upper clamping plate 2, two clamping grooves 305 respectively formed in the top of the lower clamping plate 1 and the bottom of the upper clamping plate 2, two limiting strips 306 fixed to the inner side of the clamping grooves 305, two limiting teeth 307 fixed to the inner side of the clamping grooves 305, two plug-in blocks 308 respectively fixed to the top of the lower clamping plate 1 and the bottom of the upper clamping plate 2, an elastic limiting piece 309 fixed to the outer side of the plug-in block 308, and two plug-in grooves 310 respectively formed in the top of the lower clamping plate 1 and the bottom of the upper clamping plate 2.

[0036] The bottom of the lower clamping plate 1 and the top of the upper clamping plate 2 are each provided with a communication hole 311, and the upper pressing block 302 and the lower pressing block 301 are bent away from each other, so that pressing the upper pressing block 302 and the lower pressing block 301 can drive the lower clamping plate 1 and the upper clamping plate 2 to rotate relative to each other, wherein the rough layer 4 can be formed by irregularly grinding the abutting surfaces of the lower clamping plate 1 and the upper clamping plate 2, thereby generating a rough surface for increasing the friction between the clamped object.

[0037] Need to explain, the inside of the communication hole 311 and the inside of the corresponding clamping groove 305 are connected, the corner of the communication hole 311 is arc-shaped, so that the communication hole 311 can intuitively see the clamping depth of the object after the object is clamped on the inside of the clamping groove 305, and the object needs to be covered on the limiting tooth 307, the first connecting block 303 and the second connecting block 304 are staggered, and the opposite side of the first connecting block 303 and the adjacent second connecting block 304 is fixed with a torsion spring, the front of the first connecting block 303 and the second connecting block 304 is penetrated by the same pin shaft and is hinged through the pin shaft, so that the first connecting block 303 and the second connecting block 304 can be hinged together, so that the upper pressing block 302 and the lower pressing block 301 can be relatively rotated, specifically, the first connecting block 303 and the opposite side of the adjacent second connecting block 304 are fixed with a torsion spring outside the pin shaft, so that when the upper pressing block 302 and the lower pressing block 301 are relatively rotated, the torsion spring can be elastically deformed, and then the lower clamping plate 1 and the upper clamping plate 2 are driven to move to the side close to each other under the elastic recovery of the torsion spring, facilitating control.

[0038] In addition, the left side of the clamping groove 305 is provided with an opening, so that the object outside can enter the inside, the top and bottom limiting strips 306 are located on the opposite sides of the inside of the two clamping grooves 305, and the two limiting teeth 307 inside the same clamping groove 305 are located between the opposite sides of the corresponding two limiting strips 306, so that the limiting strip 306 can cooperate with the limiting tooth 307 to clamp and position the object, the two limiting teeth 307 inside the same clamping groove 305 are symmetrically distributed around the corresponding communication hole 311, and the side of the limiting tooth 307 close to the communication hole 311 is a tooth surface, the teeth of the two limiting teeth 307 inside the same clamping groove 305 are staggered, so that the object clamped inside the clamping groove 305 can be irregularly occluded, thereby improving the stability of clamping.

[0039] At the same time, as Figure 4 and Figure 5As shown, the two plug blocks 308 are symmetrically distributed front and back, the opposite sides of the two elastic limiters 309 are both inclined surfaces, and the angle between the elastic limiter 309 and the corresponding plug block 308 is thirty degrees. The plug slot 310 can be used for the corresponding plug block 308 and the elastic limiter 309 to be plugged in at the same time. The side of the inner side of the plug slot 310 close to the opening is fixed with a matching protrusion for supporting and limiting the elastic limiter 309. The matching surface of the matching protrusion and the elastic limiter 309 is an inclined surface, so that the plug block 308 can be plugged into the inner side of the same plug slot 310 with the corresponding elastic limiter 309 at the same time, so as to limit the elastic limiter 309 on one side of the matching protrusion. Under the action between the matching protrusion and the matching surface of the elastic limiter 309, the elastic limiter 309 can move out of the inner side of the plug slot 310 when additional pressure is applied, achieving the improvement of closing stability without increasing the operation process and difficulty too much.

[0040] The working principle of the above embodiment is as follows:

[0041] In use, the lower press block 301 and the upper press block 302 are pressed, so that the lower clamping plate 1 and the upper clamping plate 2 are opened, and then the opposite side of the two clamping grooves 305 can be exposed to the outside, which is convenient for moving to the outside of the clamped object. When clamping thin objects such as cloth and children's bibs, the cloth is moved to the rough layer 4 for covering, and the lower clamping plate 1 and the upper clamping plate 2 are pressed, so that the plug block 308 is plugged into the inner side of the corresponding plug slot 310, and the elastic limiter 309 is also deformed and enters the inner side of the corresponding plug slot 310 for elastic extrusion limiting, so as to improve the stability of clamping, and then the thin object can be positioned. When clamping objects with a certain thickness and allowing a certain elastic deformation, such as folded cloth strips, stacked cloth or film, the lower press block 301 and the upper press block 302 are pressed, so that the lower clamping plate 1 and the upper clamping plate 2 are opened, and then the opposite side of the two clamping grooves 305 can be exposed to the outside, which is convenient for moving to the inner side of the clamping groove 305. The lower clamping plate 1 and the upper clamping plate 2 are pressed, so that the limiting strip 306 and the limiting tooth 307 extrude the object, and the limiting strip 306 and the limiting tooth 307 can be engaged on the outer side of the object, which is used to improve the stability of positioning. Finally, the plug block 308 is plugged into the inner side of the corresponding plug slot 310, and the elastic limiter 309 is also deformed and enters the inner side of the corresponding plug slot 310 for elastic extrusion limiting, so as to complete the clamping and positioning work.

[0042] Compared with the prior art, the fixed clamp can be conveniently used and stably clamped and positioned through the cooperation between the lower clamp plate 1, the upper clamp plate 2 and the clamp assembly between the opposite sides, so that the fixed clamp can be easily opened and closed, and can stably clamp and position the target object, and can meet the clamping requirement of thick objects, thereby effectively improving the practicality of the fixed clamp and solving the problem that the existing clamp is inconvenient to operate in actual use.
