The rear ends of the extension plate 103 are provided with sleeves, and the internal part of the sleeve is clamped with the connecting shaft of the storage turntable 3, and the extension plate 103 can be used to achieve connection with the storage turntable 3.

[0043] In the embodiment of the present disclosure, as shown in the accompanying drawings Figure 1 、 Figure 2 and Figure 4 As shown, a card hole is opened inside the inductor integrated board 4, and a card plate 401 is fixedly connected to the bottom of the inductor integrated board 4. The card plate 401 is an arc-shaped structure and is carded on the outside of the connecting shaft 102, and the opening height of the card plate 401 is smaller than the diameter of the connecting shaft 102. A displacement sensor and a multi-dimensional force sensor array are arranged inside the inductor integrated board 4. When the hunting rifle impact force test is carried out, the sensor adopts the piezoresistive principle, which can measure the force component and obtain the vector information of the impact force. The array distribution composed of multiple sensors can fully cover the force area during hunting rifle shooting and avoid measurement blind spots. After the inductor integrated board 4 is impacted, the card plate 401 disengages from the connecting shaft 102 and slides backward. The displacement sensor can be used to read the displacement distance of the inductor integrated board 4 and comprehensively evaluate the impact force.

[0044] In the embodiment of the present disclosure, as shown in the accompanying drawings Figure 3 、 Figure 6and Figure 8 As shown, a handle frame is fixedly welded to the outside of the pull plate 7, and rectangular blocks are provided at both ends of the pull plate 7, which are clamped in the inner slide groove 101. The rectangular blocks can be used to orient the movement of the inner retracting plate 61 to prevent the inner retracting plate 61 from rotating. The inside of the pull plate 7 is fastened to the elastic rope end in the sleeve by screws. After pulling the two pull plates 7, the elastic rope can be driven to move outward, thereby pulling the clamping claw group 62 to move toward the middle to clamp and fix the hunting rifle. After the clamping claw is deformed, it can fit the outer contour of the hunting rifle tightly, so it is suitable for portable hunting rifles of different models. Then, the pull plate 7 is passed from bottom to top around the storage plate 2 and then the pull plate 7 is clamped into the inner slide groove 101 and the clamping groove on the rear side of the storage plate 2 to complete the fixation of the pull plate 7.

[0045] In the embodiment of the present disclosure, as shown in the accompanying drawings Figure 5 、 Figure 6 and Figure 10 As shown, a fixed sleeve is provided on the top of the inner retracting plate 61, and clamping rods are provided on both sides of the inner retracting plate 61. The clamping rods are clamped in the inner slide groove 101. The outer sides of the two inner retracting plates 61 are respectively provided with clamping grooves. The first clamping claw 6201 and the second clamping claw 6202 are respectively provided with clamping shafts, which are clamped in the fixed sleeve at the top of the inner retracting plate 61. The inner part of the inner retracting plate 61 is clamped with a sleeve, and an elastic rope is passed through the interior of the sleeve. One end of the two outer elastic ropes is fixedly connected to the first clamping claw 6201, and one end of the two inner elastic ropes is fixedly connected to the second clamping claw 6202. The first clamping claw 6201 and the second clamping claw 6202 The positions of the splints are staggered with each other. After pulling the elastic rope, the first clamping claw 6201 and the second clamping claw 6202 are driven to move toward the middle, and the clamping claws can be used to clamp and fix the shotgun. Since the soft material of the clamping claws will undergo irregular deformation, the clamping claws can be wrapped around the outside of the shotgun to clamp and fix the shotgun, and at the same time, the wrapping is very good. After the elastic rope is fixed, the shotgun is clamped and fixed, and the preparations before the impact force test are completed. After the test is completed, the card shaft on the clamping claw is separated from the fixed sleeve of the inner receiving plate 61 to complete the disassembly and store it in the upper and lower sides of the inner card plate 201 and the main board 1 to complete the storage.

[0046] In the embodiment of the present disclosure, as shown in the accompanying drawings Figure 1 、 Figure 5 and Figure 9As shown, a locking plate 301 is provided on the top surface of the rear side of the storage rotating plate 3, a rectangular through hole is provided inside the locking plate 301, a T-slot is provided on the front side of the locking plate 301, and a slide rail clamping plate 302 is clamped inside the T-slot, and the front end of the slide rail clamping plate 302 passes through the T-slot inside the connecting shaft 102 and is clamped in the T-slot on the rear end surface of the main board 1. When the storage rotating plate 3 is rotated and stored to the bottom of the main board 1, the top of the locking plate 301 is clamped into the slot provided on the bottom surface of the storage plate 2. After the inductor integrated board 4 and the soft material board 5 are hit by the shotgun, they move backward. The slide rail clamping plate 302 provides guidance and stable support for the movement of the inductor integrated board 4 and the soft material board 5 to prevent them from tipping over, and at the same time ensures that the backward sliding distance can be measured.

[0047] In the embodiment of the present disclosure, as shown in the accompanying drawings Figure 3 and Figure 8 As shown, the front side of the soft material board 5 is covered with soft material, and the rear end face of the soft material board 5 is fixedly provided with a connecting card board 501 and a plug rod 502. The connecting card board 501 is clamped in the clamping hole inside the inductor integrated board 4, and the plug rod 502 is inserted into the front end face of the inductor integrated board 4 and the rear end of the plug rod 502 is provided with a protruding clamping ring. When the clamping ring is clamped into the inside of the inductor integrated board 4, the jamming of the clamping ring can remind the operator that the clamping is completed, thereby ensuring that the soft material board 5 can be tightly fitted to the inductor integrated board 4, ensuring the transmission of force during the impact force test and accurate measurement results.

[0048] The working principle of this embodiment is as follows: rotate the folded storage rotating plate 3 out, pull out the storage plate 2, clamp the slide rail clamping plate 302 into the T-slot on the front side of the clamping plate 301 and the T-slot on the rear end of the main board 1, rotate the inductor integrated board 4 perpendicular to the main board 1, clamp the soft material board 5 onto the inductor integrated board 4, take out the clamping assembly 6, clamp the clamping shaft on the clamping claw into the fixed sleeve at the top of the inner retracting plate 61, pass the sleeves at both ends of the elastic rope through the corresponding clamping claws and the inner retracting plate 61, and fix the ends of the elastic rope by fastening the sleeves with screws. Connect the external display screen and the data processing unit through the USB socket, place the hunting rifle between the two inner retracting plates 61, and in the device, pull the elastic rope to clamp the hunting rifle.

[0049] Check the power status of the built-in battery. If the built-in battery is low, charge it through the charging socket. When the hunting rifle impact force test is carried out, the sensor adopts the piezoresistive principle to measure the force component and obtain the vector information of the impact force. The array distribution composed of multiple sensors can fully cover the force area when the hunting rifle is shot, avoiding the measurement blind area. After the inductor integrated board 4 is impacted, the clamping plate 401 will slide backward after disengaging from the connecting shaft 102. The displacement sensor can be used to read the displacement distance of the inductor integrated board 4 and comprehensively evaluate the impact force.

[0050] The data is transmitted to the data processing unit through the USB port. The data processing unit processes the data in real time, uses various analysis algorithms to extract key parameters of the impact force, and displays the test values ​​on an external display screen.
