[0003] The common structure of current automotive repair tool carts, such as the automotive repair tool cart disclosed in patent CN210191505U, includes a push handle, a placement plate, storage holes, a cart body, a storage slot, a drawer, a handle, a partition, wheels, spring pins, a base plate, and a stop lever. The push handle is located at the rear end of the cart body, and a placement plate is located on the right side of the cart body with multiple storage holes on the top surface of the placement plate. The storage slot is located on the top surface of the cart body, and the drawer is located in the upper and lower cavities on the left side of the cart body with a handle on the surface of the drawer. Two wheels are located at the bottom of the cart body and the bottom of the base plate, respectively, making it convenient to use.

[0004] However, with the increasing intelligence and automation of vehicles, the vehicle's infotainment system needs frequent updates. These updates typically require a dedicated laptop, which is placed on top of a trolley, specifically in the storage compartment mentioned in the patent. Currently, tool carts are generally quite low, requiring maintenance personnel to bend over to operate the laptop, which is inconvenient. Furthermore, some upgrades are complex, and prolonged use can cause back pain and fatigue for maintenance personnel. Utility Model Content

[0010] Preferably, one end of the tray is connected to a shaft, and both ends of the shaft are connected to a support rod via a pivot. The lower end of the shaft is connected to a limiting rod that cooperates with the support rod. After the tray is opened horizontally, both ends of the limiting rod press against the side wall of the support rod.

[0011] Preferably, the side wall of the limiting rod is connected to a support frame for the support plate.

[0012] Preferably, the edge of the tray is provided with a retaining edge.

[0013] Preferably, the upper end of the tray is provided with an anti-slip groove.

[0014] Preferably, one side of the tray is provided with an insertion hole, a storage box is provided in the insertion hole, the bottom of the tray is provided with a limiting opening communicating with the insertion hole, and the bottom of the storage box is provided with a limiting block located in the limiting opening.

[0015] Preferably, the storage box has a positioning hole on its rear side, and the bottom of the tray has a locking bolt that connects to the positioning hole.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model features a retractable tray above the storage box, which can be adjusted to accommodate different heights, increasing comfort when using a laptop and writing notes, reducing fatigue for maintenance personnel, and making operation more convenient.

[0018] 2. The tray of this utility model can be stored on the back of the storage box when not in use, saving space and facilitating the movement of the storage box. The tray is easy to store and quick and convenient to use.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1 , Figure 2 As shown, a hand-operated tool cart for automobile repair includes a storage box 1. The bottom of the storage box 1 is equipped with casters, and a handle is provided on one side of the storage box 1. The rear end of the storage box 1 is provided with two parallel guide sleeves 4. A support rod 3 is connected inside the guide sleeves 4. A rotatable tray 2 is connected to the upper end of the support rod 3. When in use, the tray 2 is horizontally positioned above the storage box 1. When stored, the tray 2 is positioned between the two guide sleeves 4 and stands upright on one side of the storage box 1.

[0030] The guide sleeve 4 has a positioning bolt 401 on its side wall to fix the support rod 3. Maintenance personnel of different heights can adjust the height of the support plate 2 according to their height and fix the support rod 3 by the positioning bolt 401.

[0031] To prevent the support rod 3 from detaching from the guide sleeve 4, a limiting hole 402 is provided on the side wall of the guide sleeve 4, such as... Figure 6 As shown, the side wall of the support rod 3 is provided with a limiting pin 301 that cooperates with the limiting hole 402.

[0032] like Figure 3As shown, one end of the pallet 2 is connected to a shaft 203. Both ends of the shaft 203 are connected to support rods 3 via pivots 204. The lower end of the shaft 203 is connected to a limiting rod 205 that cooperates with the support rods 3. The length of the limiting rod 205 is greater than the distance between the two support rods 3. After the pallet 2 is opened horizontally, both ends of the limiting rod 205 press against the side walls of the support rods 3, thereby supporting the pallet 2 and keeping it horizontal. A support frame 206 for supporting the pallet 2 is connected to the side wall of the limiting rod 205.

[0033] The edge of the tray 2 is provided with a retaining edge 201, and the upper end of the tray 2 is provided with an anti-slip groove 202 to increase friction and improve the stability of the laptop after it is placed on the tray 2.

[0034] like Figure 4 As shown, one side of the tray 2 has an insertion hole 209, and a storage box 210 is provided inside the insertion hole 209. The bottom of the tray 2 has a limiting opening 208 that communicates with the insertion hole 209. Figure 7 As shown, the bottom of the storage box 210 is provided with a limiting block 211 located in the limiting port 208, which can prevent the storage box 210 from being pulled out of the socket 209. At the same time, the friction between the storage box 210 and the socket 209 is large, and the storage box 210 cannot be opened without external force, ensuring the reliability of use. By pushing the bottom of the storage box 210 outward from the limiting port 208, the storage box 210 can be opened. Paper and pen can be stored inside the storage box 210 for maintenance personnel to make records.

[0035] The storage box 1 has a positioning hole 101 on the rear side, and the bottom of the tray 2 has a locking bolt 207 that connects to the positioning hole 101, which can fix the tray 2 to the rear side of the storage box 1 and prevent the tray 2 from swinging.

[0036] like Figure 2 As shown, in use, after opening the locking bolt 207 and sliding the tray 2 upwards to a suitable height, the support rod 3 is fixed by the positioning bolt 401. The tray 2 is then rotated backwards approximately 270°, causing both ends of the limiting rod 205 to press against the side wall of the support rod 3, thus supporting the tray 2. At this point, the tray 2 is in a horizontal, open state, allowing a laptop to be placed on top for convenient writing and note-taking. Figure 5 As shown, after use, rotate the tray 2270° upwards to make the tray 2 vertical, open the positioning bolt 401, slide it downwards to the lowest position, and fix the tray 2 to the storage box 1 by locking bolt 207 to complete the storage.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
