[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, and several embodiments of the utility model will be provided. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0018] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] For an example, please refer to... Figure 1-2This utility model provides a technical solution:

[0021] The display screen back cover fastening device includes a worktable 1, a positioning block 2 set on the end face of the worktable 1, a safety light curtain 3 connected to the side wall of the worktable 1, a two-hand start button 4 connected to the side wall of the worktable 1, a drive cylinder 5 connected to the bottom of the inner cavity of the worktable 1, a back cover guide 6 connected to the drive end of the drive cylinder 5, and a control box 7 connected to the end face of the worktable 1.

[0022] In this embodiment, reference Figure 1 and Figure 2 The product is placed manually into the positioning block 2 on the end face of the workbench 1. The two hands control the start button 4, which activates the drive cylinder 5. The drive end of the drive cylinder 5 moves the back cover contour 6 downward, thereby locking the back cover of the display screen in place.

[0023] Furthermore, the positioning block 2 is bolted to the end face of the worktable 1, and the distance between the positioning blocks 2 can be adjusted by rotating the bolts, so that the product can be adjusted in time during positioning, thereby improving the accuracy of product positioning.

[0024] Furthermore, the safety light curtain 3 is connected to the control box 7 via a wire in an electrical connection manner.
