A regulating component for regulating the mounting box is arranged between the mounting box and the base. Two clamping plates are arranged on the inner wall of the mounting box in a reverse sliding manner collinearly. By adjusting the distance between the two clamping plates, the two clamping plates can clamp articles of different sizes. However, there are still the following defects. This manipulator has no protective device and is easily collided by external objects, resulting in damage to the manipulator. Content of the Utility Model

A protective cover is inserted into the installation groove. A fixing mechanism for fixing the protective cover is arranged in the base. The fixing mechanism includes two second chutes. The two second chutes are respectively opened on both sides of the installation groove. Plug blocks are slidably connected in the two second chutes. Springs are fixedly connected to one sides of the two plug blocks, and the springs are fixed to the base. Fixing grooves are opened on the outer walls of both sides of the protective cover, and the plug blocks are inserted into the fixing grooves. Two limiting frames are fixedly connected to the upper surface of the base. The same U-shaped rod is slidably connected in the two limiting frames. Push blocks are fixedly connected to both ends of the U-shaped rod. Two first chutes are opened on the upper surface of the base, and the first chutes are communicated with the second chutes. Driving blocks are slidably connected in the two first chutes, and the driving blocks are fixed to the plug blocks.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] Although the present disclosure will be fully described with reference to the accompanying drawings that include preferred embodiments of the present disclosure, it should be understood prior to this description that one of ordinary skill in the art may modify the invention described herein while achieving the technical effects of the present disclosure. Therefore, it should be understood that the above description is a broad disclosure to one of ordinary skill in the art, and its content is not intended to limit the exemplary embodiments described in the present disclosure.
[0021] Referring to Figure 1-Figure 3 , a protective cover for a manipulator, comprising a base 1. The upper surface of the base 1 is fixed with a manipulator 11 by bolts. An installation groove 13 is formed in the upper surface of the base 1. A protective cover 3 is inserted into the installation groove 13. A fixing mechanism for fixing the protective cover 3 is arranged in the base 1. The protective cover 3 is inserted into the installation groove 13, and the protective cover 3 is fixed on the base 1 through the fixing mechanism. The fixing mechanism includes two second chutes 16 which are respectively formed on both sides of the installation groove 13. Plug blocks 17 are slidably connected in the two second chutes 16. Springs 20 are welded to one sides of the two plug blocks 17, and the springs 20 are fixed to the base 1. Fixing grooves 14 are formed on the outer walls of both sides of the protective cover 3, and the plug blocks 17 are inserted into the fixing grooves 14. When the protective cover 3 is inserted into the installation groove 13, the protective cover 3 will push the plug blocks 17 to move outwards during the movement, and at the same time, the plug blocks 17 will squeeze the springs 20. After the protective cover 3 is completely inserted into the installation groove 13, the springs 20 push the plug blocks 17 to move inwards by the elastic force generated by being squeezed, so that the plug blocks 17 are inserted into the fixing grooves 14, thereby fixing the protective cover 3 on the base 1. Two limiting frames 5 are fixed to the upper surface of the base 1 by bolts. The same U-shaped rod 6 is slidably connected in the two limiting frames 5. Push blocks 7 are fixed to both ends of the U-shaped rod 6 by bolts. Two first chutes 15 are formed in the upper surface of the base 1, and the first chutes 15 communicate with the second chutes 16. Driving blocks 18 are slidably connected in the two first chutes 15, and the driving blocks 18 are fixed to the plug blocks 17 and are in contact with the push blocks 7. The U-shaped rod 6 drives the push blocks 7 to move outwards. Under the action of the push blocks 7, the driving blocks 18 move along the first chutes 15, and the driving blocks 18 drive the plug blocks 17 to move outwards, so that the plug blocks 17 are disengaged from the fixing grooves 14.
[0022] In the present utility model, a plurality of guide blocks 10 are fixed to the upper surface of the base 1 by bolts, and the guide blocks 10 are evenly distributed. The guide blocks 10 can facilitate the alignment and installation of the protective cover 3 into the installation groove 13. A plurality of rubber pads 2 are bonded to the bottom of the base 1, and the rubber pads 2 are evenly distributed. The rubber pads 2 can increase the friction between the device and the ground. On one side of each of the two insertion blocks 17, two guide rods 19 are fixed by bolts, and the guide rods 19 pass through the second sliding groove 16. The guide rods 19 can prevent the insertion blocks 17 from shifting when moving. On one side of the U-shaped rod 6, a handle 8 is fixed by bolts. A plurality of anti-slip lines 9 are provided on the outer side of the handle 8. When the staff member pulls the U-shaped rod 6 outward through the handle 8, the anti-slip lines 9 can increase the friction between the palm and the handle 8. A plurality of support frames 4 are fixed to the outer side of the protective cover 3 by bolts. A plurality of reinforcing ribs 12 are provided inside the protective cover 3. The support frames 4 and the reinforcing ribs 12 can increase the strength of the protective cover 3.
[0023] Working principle: When the device needs to be carried or placed for a long time, the protective cover 3 is inserted into the installation groove 13. During the movement of the protective cover 3, it will push the insertion block 17 outward. At the same time, the insertion block 17 will compress the spring 20. When the protective cover 3 is completely inserted into the installation groove 13, the spring 20 will push the insertion block 17 inward by the elastic force generated by being compressed, so that the insertion block 17 is inserted into the fixing groove 14, thereby fixing the protective cover 3 on the base 1 to prevent the device from being damaged by collision. When the device needs to be used, the staff member pulls the U-shaped rod 6 outward through the handle 8. The U-shaped rod 6 drives the push block 7 to move outward. Under the action of the push block 7, the driving block 18 moves along the first sliding groove 15. The driving block 18 drives the insertion block 17 to move outward, so that the insertion block 17 is disengaged from the fixing groove 14, and then the protective cover 3 is removed.
[0024] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
