[0019] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0020] like Figures 1 to 4 As shown, this utility model discloses a simple jack suitable for use in confined spaces, comprising a base 1, a fixed sleeve 2 vertically arranged inside the base 1, the top end of the fixed sleeve 2 penetrating the top end of the base 1 to form a channel for a lifting screw 3 to move in and out; the lifting screw 3 is threaded inside the fixed sleeve 2, and a rotating jaw 4 is provided on the upper part of the lifting screw 3, preferably without threads. During operation, a tool is clamped onto the rotating jaw 4 and rotated, causing the lifting screw 3 to move out of the fixed sleeve 2, completing the lifting operation. The operation is simple and quick. The clamping tool can be a wrench or other tools that can clamp and fix the rotating jaw 4.

[0021] Furthermore, a lifting head 5 is rotatably mounted above the rotating bayonet 4. The lifting head 5 is used to contact the object being lifted. The rotational arrangement of the lifting head 5 prevents it from rotating synchronously with the lifting screw 3 during the lifting process, thus avoiding increased wear on the object being lifted and reducing the resistance during adjustment of the lifting screw 3. In addition, in this embodiment, the base 1 consists of a circular support part 1-1 at the bottom and a frustum-shaped support part 1-2 in the middle to ensure the load-bearing capacity of the base 1; wherein the fixing sleeve 2 is disposed inside the frustum-shaped support part 1-2.

[0022] Furthermore, an operating lever 6 is provided on the rotary bayonet 4, which facilitates the adjustment of the lifting screw 3 by rotating the operating lever 6, eliminating the need for additional auxiliary tools and improving operational convenience. Preferably, a drive disk 7 is rotatably mounted on the rotary bayonet 4, and ratchet teeth 8 are elastically provided within the drive disk 7. A ratchet wheel 9 is fixedly mounted at the rotary bayonet 4 within the drive disk 7; the operating lever 6 is mounted on the drive disk 7. The ratchet wheel 9 and ratchet teeth 8 facilitate the adjustment of the position of the operating lever 6, thereby improving the convenience of adjusting the lifting screw 3 in confined spaces.

[0023] Furthermore, in this embodiment, the length of the operating lever 6 is adjustable, allowing for flexible adjustment based on the size of the operating space, facilitating operation and use. It also increases the ease of adjusting the torque-lifting screw 3. Specifically, the operating lever 6 includes a sleeve 6-1 connected to the drive disc 7. A support rod 6-2 is slidably disposed within the sleeve 6-1, and a locking bolt 6-3 is threaded at the end of the sleeve 6-1 to fix the support rod 6-2. When adjusting the length of the operating lever 6, simply loosen the locking bolt 6-3 and move the support rod 6-2; the operation is simple and quick.

[0024] Furthermore, a hinge plate 10 is provided on the drive disk 7, and the operating lever 6 is hinged to the hinge plate 10. The hinged design of the operating lever 6 makes it easy to store it after use, reducing the occupation of surrounding horizontal space. Preferably, a storage groove 11 is provided on the base 1 along the vertical direction, which can be used to store the operating lever 6, further reducing the jack's occupation of external space and improving the convenience of storage and carrying.

[0025] In use, the jack is placed between the support surface and the part or object to be lifted. Then, the operating lever 6 is rotated to drive the lifting screw 3 to rotate, so that the lifting screw 3 is lifted from the fixed sleeve 2, thereby achieving the purpose of lifting the object or part. By swinging the operating lever 6 back and forth, the ratchet 9 and ratchet 8 can be used to improve the convenience of adjusting the lifting screw 3. The structure is simple, the operation is convenient, and the practicality is strong.
