In another technical solution, the rack 72 has an angle of 0-15 ° with the horizontal plane. With this arrangement, the blocking effect is enhanced.

In another embodiment, the rack 72 is disposed obliquely upward in a direction away from the channel. With this arrangement, the blocking effect is enhanced.

In another technical scheme, a first pulley 80 and a second pulley 81 are sequentially arranged at the bottom end of the rack 72 along a direction close to the channel, each of the first pulley 80 and the second pulley 81 comprises a central shaft, a support rod 82 fixedly connected between the middle of the central shaft and the bottom end of the rack 72, and rolling bearings arranged on two sides of the central shaft in a rolling manner, the first pulley 80 is located at one end of the rack 72 far away from the channel, the support rod 82 is used for connecting the central shaft and the rack 72 so as to fix the first pulley 80/the second pulley 81 at the bottom end of the rack 72, the rolling bearings are rotatably connected with the central shaft, and the specifications of the first pulley 80 and the second pulley 81 are determined according to actual conditions;

a sliding rod 9 is arranged at the bottom end of the rack 72 of the frame 1, a first sliding groove 90 matched with the first pulley 80 is concavely arranged at the top end of the sliding rod 9, a first rolling groove for accommodating a rolling bearing of the first pulley 80 is concavely arranged at the bottom end of the first sliding groove 90, a second rolling groove 91 for accommodating a rolling bearing of the second pulley 81 is arranged at the top end of the sliding rod 9, and the top surface of the sliding rod 9 is a plane;

when the rack 72 passes through the chassis, the first pulley 80 rolls to the lower end of the first chute 90, and the second pulley 81 rolls to the lower end of the second chute; when the rack 72 retracts into the housing, the first pulley 80 rolls to the high end of the first sliding groove 90, and the second pulley 81 rolls to the high end of the second sliding groove. The arrangement of the second rolling groove 91 is determined according to actual conditions, if the second rolling groove 91 is overlapped with the first rolling groove in the length direction of the sliding rod 9, the second rolling groove 91 can be arranged on two sides of the opening at the top end of the first pipe groove, the second roller wheel is adjusted correspondingly, if the second rolling groove 91 is not overlapped with the first rolling groove in the length direction of the sliding rod 9, the second rolling groove 91 is arranged on the top surface of the sliding rod 9, and the second roller wheel is adjusted correspondingly.

In another embodiment, the outer periphery of the second sliding chute protrudes upward to form a supporting seat 92, and the bottom end of the rack 72 is slidably supported on the supporting seat 92. By adopting the scheme, the relative friction between the bottom end of the rack 72 and the sliding rod 9 is reduced, and the support stability is improved.
