By setting the limiting structure 8, it is convenient to clamp and limit the mop, so as to avoid the situation that the limiting is not stable enough and easy to fall off due to the material problem of the mop, thereby ensuring the stability of the limiting of the mop and improving the working efficiency of the mop detection. A cleaning structure 9 is provided on the surface of the driving block 5, and by setting the cleaning structure 9, it is convenient to clean the surface of the threaded rod 4 when the driving block 5 moves, so as to avoid the situation that the broken hair and impurities generated by the breakage of the mop during the test are attached to the surface of the threaded rod 4 to affect the movement of the driving block 5, and then the threaded rod 4 is protected.
[0031] The specific settings and functions of the limiting structure 8 and the cleaning structure 9 will be described in detail below.
[0032] Reference Figure 2 - Figure 5As shown, in this embodiment: the limiting structure 8 includes a U-shaped plate 801, the U-shaped plate 801 is fixedly connected to one end of the connecting rod 7, a screw 802 is threaded through the surface of the U-shaped plate 801, one end of the screw 802 is rotatably connected to a rectangular plate 803, a side of the rectangular plate 803 away from the screw 802 is fixedly connected to a plurality of spikes 804, and a side of the U-shaped plate 801 close to the spikes 804 is provided with a plurality of grooves 805, and the size of the grooves 805 is adapted to the size of the spikes 804. The two sides of the rectangular plate 803 are fixedly connected with extension plates 806, and the surface of the extension plates 806 is slidably penetrated by round rods 807, and both ends of the round rods 807 are fixedly connected with the surface of the U-shaped plate 801. When the rectangular plate 803 moves, it will drive the extension plates 806 to move, and the extension plates 806 will slide along the surface of the round rods 807. The round rods 807 limit the movement path of the extension plates 806, and then limit the movement path of the spikes 804, so as to ensure that the spikes 804 can be inserted into the grooves 805. The end of the threaded rod 4 away from the rectangular plate 803 is fixedly connected with a circular plate 808, and the arc surface of the circular plate 808 is evenly fixedly connected with a plurality of protrusions 809. When the circular plate 808 is rotated, the rotation of the circular plate 808 will drive the protrusions 809 to rotate, and the rotation of the circular plate 808 will drive the screw 802 to rotate. The circular plate 808 can achieve the effect of facilitating the rotation of the threaded rod 4, and the protrusions 809 can prevent the hand from slipping when the circular plate 808 is rotated. The surface of the rectangular plate 803 slides through two brackets 810, and the surfaces of the two brackets 810 are fixedly connected with a pressure plate 812. The surface of the bracket 810 is fixedly connected with a first spring 811, and the other end of the first spring 811 is fixedly connected to the rectangular plate 803. The rectangular plate 803 will drive the bracket 810 to be squeezed on the inner wall of the U-shaped plate 801. The bracket 810 will slide in the rectangular plate 803 due to the squeezing. At this time, the first spring 811 will be gradually compressed. When the bracket 810 moves, it will drive the pressure plate 812 to move. The movement of the pressure plate 812 will squeeze the rag, and the rag will gradually fall off from the surface of the spikes 804. The pressure plate 812 serves to facilitate the removal of the rag from the surface of the spikes 804.
[0033] Reference Figure 6As shown, specifically, the cleaning structure 9 includes a fixed block 91, which is fixedly connected to the surface of the driving block 5, and a rectangular rod 92 is slidably penetrated on the surface of the fixed block 91, and a cleaning block 94 is fixedly connected to one end of the rectangular rod 92 close to the threaded rod 4, and a plurality of bristles 95 are fixedly connected to the surface of the cleaning block 94, and a second spring 93 is sleeved on the surface of the rectangular rod 92, and the two ends of the second spring 93 are respectively fixedly connected to the fixed block 91 and the rectangular rod 92. A latch 96 is slidably inserted on the surface of the fixed block 91, and a limiting hole 97 is provided on the surface of the rectangular rod 92. The size of the latch 96 matches the size of the limiting hole 97. The latch 96 is pressed to be inserted into the limiting hole 97, thereby limiting the position of the cleaning block 94, and then facilitating the cleaning of the bristles 95 on the surface of the cleaning block 94. One end of the rectangular rod 92 away from the cleaning block 94 is fixedly connected to a driving plate 98 , the cross section of the driving plate 98 is “U”-shaped, and the movement of the driving plate 98 will drive the rectangular rod 92 to move, so that the driving plate 98 facilitates the pulling of the rectangular rod 92 .
[0034] Working principle: when it is necessary to perform tension test on the rag, first put the edge of the rag into the two U-shaped plates 801, and then rotate the circular plate 808. The rotation of the circular plate 808 will drive the protrusion 809 to rotate, and the rotation of the circular plate 808 will drive the screw 802 to rotate. The rotation of the screw 802 will move in the U-shaped plate 801 with the help of the thread. The movement of the screw 802 will drive the rectangular plate 803 to move, and the movement of the rectangular plate 803 will drive the spike 804 to move in the direction close to the groove 805. When the rectangular plate 803 moves, it will drive the extension plate 806 to move. The movement of the extension plate 806 will slide along the surface of the round rod 807. The round rod 807 reaches the limit of the movement path of the extension plate 806, and then limits the movement path of the spike 804, so as to ensure that the spike 804 can be inserted into the groove 805. When the spike 804 moves to a suitable position, it will pierce into the rag. The spike 804 passes through the rag and is inserted into the groove 805. The rectangular plate 803 will squeeze the rag The rag is pressed against the inner wall of the U-shaped plate 801, thereby limiting the position of the rag, and making it easier to detect the tension of the rag. After the rag is detected, the circular plate 808 is rotated in the opposite direction, and the screw 802 moves in the U-shaped plate 801 with the help of the rotation of the circular plate 808. The movement of the screw 802 drives the rectangular plate 803 to move, and the movement of the rectangular plate 803 drives the spike 804 to move away from the groove 805. The movement of the rectangular plate 803 drives the bracket 810 to move. When the rectangular plate 803 moves to a suitable position, the rectangular plate 803 drives the bracket 810 to be pressed against the inner wall of the U-shaped plate 801, and the bracket 810 is squeezed and slides in the rectangular plate 803. At this time, the first spring 811 is gradually compressed, and the bracket 810 drives the pressure plate 812 to move when moving. The movement of the pressure plate 812 squeezes the rag, and the rag gradually falls off from the surface of the spike 804. The pressure plate 812 serves to facilitate the removal of the rag from the surface of the spike 804.
[0035] When the rag is subjected to a tensile test, after the rag is limited, the threaded rod 4 is driven, and the threaded rod 4 will drive the driving block 5 to move by means of the thread. The movement of the driving block 5 will drive the fixed block 91 to move, and the movement of the fixed block 91 will drive the rectangular rod 92 to move. The movement of the rectangular rod 92 will drive the cleaning block 94 to move. The movement of the cleaning block 94 will drive the bristles 95 to slide along the surface of the threaded rod 4, thereby brushing off the impurities on the surface of the threaded rod 4. After the rag is tested, the driving plate 98 is pulled, and the movement of the driving plate 98 will drive the rectangular rod 92 to move. The movement of the rectangular rod 92 will slide in the fixed block 91. The movement of the rectangular rod 92 will stretch the second spring 93. At this time, the second spring 93 is in a stretched state. The movement of the rectangular rod 92 will drive the cleaning block 94 to move away from the threaded rod 4. When the cleaning block 94 moves to a suitable position, the latch 96 is pressed to insert the latch 96 into the limiting hole 97, thereby limiting the position of the cleaning block 94, and making it easier to clean the bristles 95 on the surface of the cleaning block 94.
