The second fixing plate 21 is located between the second fixing member 162 and the foot pedal part of the next stage fishing rod step 100. The second fixing plate 21 is used to press and fix the foot pedal part of the next stage fishing rod step 100 onto the first sliding arm 161.

[0051] The two ends of the second movable scapula 17 are respectively threaded to two ball screws 12. The two ball screws 12 synchronously drive the second movable scapula 17 to move up and down. The second movable scapula 17 has the same structure as the first movable scapula 15, and the second movable scapula 17 is located directly below the first movable scapula 15.

[0052] Reference Figure 1 and Figure 4 There are two third fixing components 18. The third fixing components 18 are slidably connected to the second movable shoulder 17 in the horizontal direction. The two third fixing components 18 are used to fix and press down the previous fishing rod step 200. In use, by adjusting the position of the two third fixing components 18 on the second movable shoulder 17, the two third fixing components 18 are respectively fixed to both sides of the footrest part of the previous fishing rod step 200.

[0054] The third fixing member 182 is provided with a third fixing plate 23, which is located between the third fixing member 182 and the foot pedal part of the previous fishing rod step 200, and the third fixing plate 23 is used to unlock the locking device on the foot pedal part of the previous fishing rod step 200.

[0055] During the experiment, the ball screw 12 drives the first moving shoulder 15 and the second moving shoulder 17 to press down. The first sliding arm 161 on the first moving shoulder 15 presses down on the foot pedal part of the next stage fishing rod step 100, and the second sliding arm 181 on the second moving shoulder 17 presses down on the foot pedal part of the previous stage fishing rod step 200. Pressure sensors can be installed on the first sliding arm 161 and the second sliding arm 181 to display the pressing pressure of the first sliding arm 161 and the second sliding arm 181 in real time. The pressing pressure can be set according to the actual test requirements.

[0060] This application also discloses a cyclic testing method for a fishing rod ladder locking device based on the above-described cyclic testing device for conducting cyclic tests.

[0061] Specifically, the cyclic testing method for the fishing rod ladder locking device includes the following steps:

[0062] S1. Adjust the positions of the first movable scapula 15 and the second movable scapula 17;

[0063] Start the power unit 13. The power unit 13 drives the first moving scapula 15 and the second moving scapula 17 to move through the ball screw 12, and adjusts the first moving scapula 15 and the second moving scapula 17 to the preset position.

[0064] S2. Installation and fixation of the fishing rod ladder on the cyclic test device of the fishing rod ladder locking device;

[0065] S21. First, adjust the position and distance of the two first fixing parts 14 on the base 11 based on the distance of the previous fishing rod step 200 so that the two first fixing parts 14 can be adapted to the installation of the bottom of the previous fishing rod step 200. Then, insert the bottom of the previous fishing rod step 200 into the first fixing parts 14 and fix it.

[0066] S22. Based on the width of the next level fishing rod step 100, the position and distance of the two first sliding arms 161 on the first moving shoulder 15 are adaptively adjusted to facilitate the installation of the fishing rod ladder.

[0067] Then, based on the width of the previous fishing rod step 200, the position and distance of the two second sliding arms 181 on the second moving shoulder 17 are adaptively adjusted to facilitate the installation of the fishing rod ladder.

[0068] S23. Pull the next stage fishing rod step 100 out from the foot pedal part of the previous stage fishing rod step 200, and make the locking device on the foot pedal part of the previous stage fishing rod step 200 lock and fix the foot pedal part of the next stage fishing rod step 100.

[0070] S3. Start the power unit 13 and cause the ball screw 12 to drive the first moving shoulder 15 and the second moving shoulder 17 to press down, so that the first sliding arm 161 presses down on the foot pedal part of the next stage fishing rod step 100, and the second sliding arm 181 presses down on the foot pedal part of the previous stage fishing rod step 200, until the pressure applied by the first sliding arm 161 to the foot pedal part of the next stage fishing rod step 100 and the pressure applied by the second sliding arm 181 to the foot pedal part of the previous stage fishing rod step 200 reach the preset pressure and are maintained for a time T seconds.

[0071] The preset pressure can be set by the user and can be the same as the national standard, for example, the preset pressure can be set to 750N. The time T seconds can also be set by the user and can also be the same as the national standard, for example, the time T seconds can be 3 to 5 seconds.

[0072] The power unit 13 is reversed and the first moving shoulder 15 and the second moving shoulder 17 are driven upward through the ball screw 12 to release the downward pressure on the foot pedal of the next fishing rod step 100 and the foot pedal of the previous fishing rod step 200. At the same time, the third fixing member 182 releases the locking device on the foot pedal of the previous fishing rod step 200, and then the next fishing rod step 100 falls into the previous fishing rod step 200.

[0073] S4. Repeat steps S23 to S3 until the number of cyclic tests of the fishing rod ladder locking device reaches the preset number of tests.

[0074] The preset number of tests can be set by the user and can be the same as the national standard. For example, the preset number of tests can be set to 1000.
