[0021] As shown in the accompanying Figure 1 to the accompanying Figure 3 drawings:

[0022] The utility model provides a kind of tool car anti-trap chassis, including tool car chassis 1, mounting seat 2 and escape mechanism 3, the tool car chassis 1 is fixedly installed with the mounting seat 2 of two two as a group, the bearing shaft 31 of the escape mechanism 3 is rotatably installed on each mounting seat 2, two fixed sleeve kits 32 are symmetrically installed on each bearing shaft 31, and escape plate 33 is fixedly installed on each fixed sleeve kit 32, and escape bottom plate 34 is fixedly installed on the escape plate 33;The bearing shaft 31 is fixedly installed with worm gear 35, and the driving worm 36 is rotatably installed in the tool car chassis 1 and engaged with worm gear 35.

[0023] Further, a handle 4 that can rotate is designed outside the tool car chassis 1. The handle 4 is firmly connected with one end of the driving worm 36 rotatably installed inside the tool car chassis 1. By rotating the handle 4, the driving worm 36 is directly driven to rotate. This design not only simplifies the operation process, but also enables the user to more conveniently control the deployment and stowage of the escape mechanism.

[0024] Further, four universal wheels 5 are installed at the bottom corners of the tool cart chassis 1. These universal wheels 5 are located on one side of the mounting seat 2, providing the tool cart with good mobility and flexibility. Through the universal wheels 5, the tool cart can easily move on various terrains while maintaining a stable driving state.

[0025] Further, the universal wheels 5, the fixed sleeve 32, the escape plate 33, and the escape bottom plate 34 are all located in the same vertical plane. This design ensures that the universal wheels 5 do not interfere with any part of the escape mechanism 3 during driving, thereby ensuring that the escape mechanism can freely deploy and retract without affecting the normal driving of the tool cart.

[0026] Further, the cross-section of the escape bottom plate 34 is designed as an arc surface, which allows the escape bottom plate 34 to better adapt to various complex terrains, increasing the contact area and friction with the ground. In addition, a escape wheel 37 is rotatably installed at one end of the escape bottom plate 34. This escape wheel 37 can come into contact with the ground when needed, reducing friction and helping the tool cart to easily escape, making it easier to push the tool cart out of the area where it is trapped.

[0027] Further, when the escape wheel 37 comes into contact with the ground, the universal wheels 5 near the bottom escape wheel 37 will automatically disengage from the ground. This design avoids interference and damage to the universal wheels 5 during the escape process, while also improving the safety and stability of the system.

[0028] Further, finally, a protective cover 6 is installed at the middle of the bottom of the tool cart chassis 1. The bearing shaft 31 passes through the protective cover 6 for rotation, while the worm gear 35 is fixed to the bearing shaft 31 and located inside the protective cover 6. This protective cover 6 not only protects the worm gear transmission mechanism from external interference and damage, but also improves the reliability and stability of the entire system.

[0029] The working principle is as follows: first, when the tool cart is trapped, the user will notice that the vehicle cannot escape on its own. At this time, the user can start operating the tool cart anti-trap chassis provided by the present utility model. On the outside of the tool cart chassis 1, there is a rotatable handle 4. The user can directly drive the driving worm 36 connected to the handle 4 by rotating the handle 4.

[0030] Then, as the drive worm 36 rotates, the worm gear 35 engaged with it will also begin to turn. The worm gear 35 is fixed in the middle of the carrier shaft 31, so the carrier shaft 31 will also rotate. The carrier shaft 31 is symmetrically installed with two fixed sleeves 32, and each fixed sleeve 32 is fixedly installed with a escape plate 33, and the escape plate 33 is fixedly installed with an escape bottom plate 34. Therefore, when the carrier shaft 31 rotates, the escape bottom plate 34 will also rotate, thereby unfolding the escape mechanism 3.

[0031] During the unfolding of the escape mechanism 3, the arc-shaped design of the escape bottom plate 34 allows it to better adapt to various complex terrains, increasing the contact area and friction with the ground. At the same time, the escape wheel 37 at one end of the escape bottom plate 34 will also come into contact with the ground. This escape wheel 37 can reduce friction and help the tool car escape easily. At this time, the universal wheel 5 near the escape wheel 37 will automatically come into contact with the ground, avoiding interference and damage to the universal wheel 5 during the escape process.

[0032] As the escape mechanism 3 is further unfolded, the user can feel that the tool car is gradually escaping from the predicament. During the escape process, the user can adjust the degree of unfolding of the escape mechanism 3 by continuing to rotate the handle 4 to adapt to different terrains and escape requirements.

[0033] Finally, when the tool car successfully escapes, the user can reverse the rotation of the handle 4, causing the drive worm 36 to rotate in the opposite direction. In this way, the worm gear 35 and the carrier shaft 31 will also rotate in the opposite direction, causing the escape mechanism 3 to gradually retract. After the escape mechanism 3 is completely retracted, the tool car can continue to be pushed normally.

[0034] During the entire escape process, the protective cover 6 below the tool car chassis 1 protects the worm and gear transmission mechanism from external environmental interference and damage. This not only improves the reliability and stability of the entire system, but also prolongs the service life of the tool car.

[0035] Using the technical solution described in the utility model, or inspired by the technical solution of the utility model, similar technical solutions can be designed to achieve the above technical effects, which are within the protection scope of the utility model.
